Abstract:
Understanding migratory requirements is critical for the conservation of diadromous fishes. Tupong (Pseudaphritis urvillii) are diadromous fishes found in freshwater and estuarine regions of south-eastern Australia. Previous studies have hypothesised that mature female tupong undertake downstream spawning migrations from freshwater to the estuary or sea, with a compensatory return of juveniles, and possibly spent fish, back upstream. We applied acoustic telemetry to test this hypothesis. We tagged 55 female tupong in two river systems in Victoria, Australia, and tracked movements for 4- to 6-month periods over 2 years. Thirty-one fish undertook rapid downstream migrations and then appeared to move through the estuary and out to sea between May and August in each year. Migration was associated with relatively high river discharges, and movement from the estuary to the sea tended to occur most frequently during intermediate moon phases. Low rates of movement between September and April suggested that tupong inhabited restricted home ranges outside of the spawning season. The apparently disparate migratory patterns of female (catadromous) and male (non-diadromous) tupong are rare amongst fishes globally. Differential exertion of a range of selective pressures may have resulted in the evolution of sexual differences in migratory modes in this species.

Full text
Abstract:
Stomach contents from 285 pelagically feeding Australian salmon (Arripis truttaceus) caught in Western Port, Victoria, between May 1992 and June 1993 were examined. Stomach contents consisted of three species of clupeoid fishes. These were, in order of importance, anchovy (Engraulis australis), pilchard (Sardinops neoplchardus) and sandy sprat (Hyperlophus vittatus). The diet of A. truttaceus varied on a seasonal basis, both in terms of prey species composition and prey age (juvenile or adult). Adult anchovy were the dominant food item between October and January. In May 1992 and in February and March 1993, juvenile clupeoids dominated gut samples, with most of these being anchovy and pilchard. Sandy sprat comprised a significant component of gut samples in May 1992 and June 1993. Two size groups of salmon were temporarily resident in Western Port. The largest salmon were caught in October and November, and these were replaced by a smaller size group that dominated catches between December and June. The arrival of A. truttaceus subadults in Western Port in spring and their gradual departure from the bay in the late autumn and winter appears to be closely tied to the seasonal inshore/offshore migrations of prey species.

Full text
Abstract:
The importance of soft-bodied zooplankton as predators of fish eggs and larvae was examined during March–June, 1983 in Kulleet Bay, Vancouver Island, British Columbia. The diet of the jellyfish Aequorea victoria was evaluated by gut content analysis of individually collected specimens. Crustacean zooplankters were eaten in lesser proportion, and larvaceans, fish larvae, hydromedusae, and siphonophores were eaten in greater proportion than their presence in the environment. Numerous herring larvae (Clupea harengus pallasi) were consumed, as well as the larvae of fishes in several other families (primarily Pleuronectidae, Cottidae, Scorpaenidae, Stichaeidae, Pholidae, and Gadidae), and the pelagic eggs of flatfish (Family Pleuronectidae). When herring larvae hatched in mid-March, A. victoria medusae in the bay contained an average of 22 herring larvae each, comprising 48% of all ingested prey. The predation rates on herring and other fish larvae were calculated from the numbers of larvae in A. victoria, the digestion times, and the field densities of medusae and larvae. Accordingly, 4 newly-hatched herring larvae∙m−3∙d−1 (0.7%∙d−1) were consumed by A. victoria but few were eaten after April 5–6. Predation on other fish larvae was [Formula: see text] larvae∙m−3∙d−1 during April 5 to May 3, but was not detectable in samples collected during May 9 to June 7. Other soft-bodied predators (ctenophores, chaetognaths, siphonophores, and other hydromedusae) contained few fish larvae.

Full text
Abstract:
A study was made of the concentration of the naturally occurring radionuclide polonium-210 in the livers of cartilaginous fishes (chondrichthyans) caught in the waters of Port Phillip Bay, Victoria, Australia in 1991. Five elasmobranch species had 210Po concentrations in the range 1-31 Bq kg-1 (wet weight) and one holocephalian species, the elephant fish (Callorhynchus milii), was exceptional with a 210Po range of 60-270 Bq kg-1 (n=3, mean 180 Bq kg-1). Lead-210 was present at 0.1- 1.1 Bq kg-1 and activity concentration ratios of 210Po:210Pb were all greater than 1, indicating that the 210Po could not all have grown in from in situ decay of 210Pb within the chondrichthyan liver. The concentration of 210Po in the livers appeared to be species related. Concentrations of the trace metals Cu, Fe and Zn showed no correlation with the 210Po and were not species-related. The mean concentration of 210Po measured in Port Phillip Bay water was 0.32 mBq kg-1. This yields concentration factors of 3.2 × 103 to 8.4 × 105 for unsupported 210Po in the livers of the chondrichthyans. The total 210Po (using Q=20) exposes the livers to a weighted absorbed dose of up to 140 mGy year-1 (16�Gy h-1), which is >99% of the total internal dose and three orders of magnitude greater than the external dose based on estimated levels of 40K.

Full text
Abstract:
A small collection of arthrodire remains is described from the Devonian Aztec Siltstone of southern Victoria Land, Antarctica. Barwickosteus antarcticus, gen. et sp. nov., is a small phlyctaeniid arthrodire probably closely related to Barrydalaspis from the Bokkeveld Group of South Africa. Grifftaylor antarcticus, gen. et sp. nov., is a generalised phlyctaeniid resembling Phlyctaenius and Neophlyctaenius. New specimens of Boomeraspis show that it had a high-spired trunk-armour with a median dorsal plate of similar proportions to Tiaraspis, Mithakaspis, Turrisaspis or Africanaspis. Other fragmentary median dorsal plates are provisionally referred to Turrisaspis and Mulgaspis. With these new taxa the vertebrate assemblage from the Aztec Siltstone comprises at least 37 genera and 50 species, making it one of the most diverse of Middle–Late Devonian age.

Full text
Abstract:
Understanding the migratory behaviour of fishes is critical to the conservation and management of fish assemblages in coastal rivers. We analysed the otolith chemical signatures of smelt, Retropinna sp., from inland and coastal populations in mainland south-eastern Australia to determine whether individuals within coastal populations of the species were diadromous. Assessments of otolith chemical composition combined with water chemistry data were used to make inferences about the migration histories of individual fish. A proportion of the smelt collected from the freshwater reaches of a coastal river exhibited diadromous movements, with the majority of fish analysed showing evidence of estuarine or marine occupation as larvae/juveniles and a minority inhabiting freshwater throughout their life histories. A broad range in the daily ages of upstream migration into freshwater (15–106 days) and the timing of these migrations suggest that spawning and migration occur over several months during the summer/autumn period. The results of this study suggest that southern smelts are an ecologically variable taxonomic group and that conservation and management actions should take into account the range of migratory behaviours exhibited both within populations and across regions.

Abstract:
Abstract Color patterns in African cichlid fishes vary spectacularly. Although phylogenetic analysis showed already 30 years ago that many color patterns evolved repeatedly in these adaptive radiations, only recently have we begun to understand the genomic basis of color variation. Horizontal stripe patterns evolved and were lost several times independently across the adaptive radiations of Lake Victoria, Malawi, and Tanganyika and regulatory evolution of agouti-related peptide 2 (agrp2/asip2b) has been linked to this phenotypically labile trait. Here, we asked whether the agrp2 locus exhibits particular characteristics that facilitate divergence in color patterns. Based on comparative genomic analyses, we discovered several recent duplications, insertions, and deletions. Interestingly, one of these events resulted in a tandem duplication of the last exon of agrp2. The duplication likely precedes the East African radiations that started 8–12 Ma, is not fixed within any of the radiations, and is found to vary even within some species. Moreover, we also observed variation in copy number (two to five copies) and secondary loss of the duplication, illustrating a surprising dynamic at this locus that possibly promoted functional divergence of agrp2. Our work suggests that such instances of exon duplications are a neglected mechanism potentially involved in the repeated evolution and diversification that deserves more attention.

Abstract:
Abstract The adaptive radiation of cichlid fishes in East African Lake Malawi encompasses over 500 species that are believed to have evolved within the last 800,000 years from a common founder population. It has been proposed that hybridization between ancestral lineages can provide the genetic raw material to fuel such exceptionally high diversification rates, and evidence for this has recently been presented for the Lake Victoria region cichlid superflock. Here, we report that Lake Malawi cichlid genomes also show evidence of hybridization between two lineages that split 3–4 Ma, today represented by Lake Victoria cichlids and the riverine Astatotilapia sp. “ruaha blue.” The two ancestries in Malawi cichlid genomes are present in large blocks of several kilobases, but there is little variation in this pattern between Malawi cichlid species, suggesting that the large-scale mosaic structure of the genomes was largely established prior to the radiation. Nevertheless, tens of thousands of polymorphic variants apparently derived from the hybridization are interspersed in the genomes. These loci show a striking excess of differentiation across ecological subgroups in the Lake Malawi cichlid assemblage, and parental alleles sort differentially into benthic and pelagic Malawi cichlid lineages, consistent with strong differential selection on these loci during species divergence. Furthermore, these loci are enriched for genes involved in immune response and vision, including opsin genes previously identified as important for speciation. Our results reinforce the role of ancestral hybridization in explosive diversification by demonstrating its significance in one of the largest recent vertebrate adaptive radiations.

Full text
Abstract:
The ichthyoplankton assemblage of the Hopkins River estuary, Victoria, was dominated by estuarine taxa that included demersal (goby, gudgeon) and pelagic (black bream, estuary perch, anchovy) species. The two seasonal peaks in fish larvae abundance were related to (1) the spring/summer zooplankton increase that occurred after flooding of the estuary and was comprised predominantly of copepod nauplii, thereby providing a good prey field for very young fish larvae, and (2) the autumn zooplankton maxima, which would provide a wide selection of copepod stages and meroplankton and promote dietary partitioning and flexibility among older larval stages. The two peaks in fish larvae abundance occurred well before and well after the attainment of maximum water temperature in the estuary. Goby, gudgeon, estuary perch and anchovy larvae were in the plankton over an extended period coinciding with the more stable conditions of salt-wedge presence and maximum zooplankton densities. The spawning of black bream and anchovies in the estuary was clearly related to physical conditions, such as salinity and water temperature, and habitat-although spawning of both species also occurred at times of high concentrations of potential prey organisms for their larvae. Adults of all the above fish species appear to have evolved spawning strategies that are adapted to the average hydrological and biological conditions in the estuary that would lead to the enhanced survival of their larvae. With the exception of the black bream, it appears that a ubiquitous and prolonged rather than a synchronous and confined spawning strategy is more widely used by estuarine-spawning fishes in the Hopkins River estuary. This type of spawning strategy, combined with the generally high density of food available to fish larvae in estuaries, suggests that the match-mismatch hypothesis of Cushing may be less relevant in the estuarine than in the marine environment.

Abstract:
Understanding the reasons and cues for migration is crucial for developing effective conservation and management strategies of diadromous fishes. Spawning and movement patterns of the threatened diadromous Australian grayling (Prototroctes maraena) were investigated in the Bunyip River, Victoria, using drift sampling (2008–2011) and acoustic telemetry (2009–2010) during the autumn–winter spawning period of each year. Fifty-five adult fish (2009: n = 21; 2010: n = 34) were tagged and released in February ~15–30 km upstream of the Bunyip River estuary. Thirteen fish (2009: n = 7; 2010: n = 6) undertook rapid downstream migrations from March to April to reaches immediately upstream of the estuary. Drifting eggs were detected at multiple sites between April and July; however, the majority (78.8%) were collected in the lower reaches within ~0.5 km of the estuary in early–mid-May. Tagged adult fish arrived in this area 1–4 weeks before eggs were detected and usually moved back upstream within 2 weeks following the peak egg abundance. Downstream migration and peak egg abundance were associated with increased river flows. Although the proportion of fish that undertook migrations was low, low rates of tag retention in this species likely account for the failure to detect migration by many of the tagged individuals.

Abstract:
The Scripps Institution of Oceanography (SIO) at the University of California, San Diego maintains one of the largest combined oceanographic collections in the world comprising four collections: Geological (sediment cores and dredged rocks), Pelagic Invertebrates, Benthic Invertebrates and Marine Vertebrates. After surviving threats of dissolution, the SIO Collections are now securely funded and have been able to make other collections available to the scientific community. Over the last few years, both the Marine Vertebrate (SIO-MVC) and Benthic Invertebrate (SIO-BIC) Collections have received National Science Foundation (NSF) and institutional funding to integrate important at-risk collections from University of California, Los Angeles (UCLA), the Monterey Bay Aquarium Research Institute (MBARI) and the University of Victoria. The UCLA Ichthyological Collection, around 9000 lots, was at risk of disposal due to hazardous material concerns and lack of institutional support. The collection, accumulated primarily under Boyd Walker (1949-1980) and later Don Buth (1980-), contains material from extensive surveys of the near-shore fishes of Southern California, Baja California and the Tropical Eastern Pacific including remote oceanic islands such as the Revillagigedos, Clipperton and the Galapagos. The UCLA collection also contains over 150 secondary types and over 100 species new to the SIO-MVC. Due to lack of support, the collection records were never digitized and the collection was minimally curated and its holdings were poorly known. For over two years, the collection manager and student employees have physically re-curated and integrated this material into the SIO-MVC. These data are now available online via iDigBio and VertNet and have already been used in numerous studies. The SIO-BIC, holding 45,000 lots, is accepting ownership of two deep-sea animal collections from Verena Tunnicliffe at the University of Victoria and Robert Vrijenhoek at MBARI. These collections include 10,900+ lots, largely from hydrothermal vents across the Pacific. Collected over 35 years from remote deep-sea sites that are difficult and expensive to access, these collections represent a major resource for systematics, genetics, and ecology. With Dr. Vrijenhoek now retired and Dr. Tunnicliffe nearing retirement, their collections were at risk of being lost. This material will be made discoverable online through the SIO-BIC database and iDigBio, and will be available for loan and examination. In the last year, the collection manager and five undergraduate employees have integrated some 3,000 lots. With support from the institution and the NSF, the SIO collections are solidifying their roles as central repositories for deep-sea and Eastern Pacific fauna.

Abstract:
Riverine fishes are among the most imperilled fauna in the world; however, for many species, there is little or no understanding of their ecological requirements. The Australian grayling (Prototroctes maraena) is a small diadromous fish endemic to rivers in south-eastern Australia that has declined considerably in range and abundance and is listed as threatened nationally. To improve understanding of the species’ movement ecology and to inform the development of conservation management actions, we examined the day-to-day movements and habitat use of Australian grayling (n=7) over 8 weeks by using radio-telemetry. Tagged individuals of Australian grayling typically occupied restricted (i.e. tens to hundreds of metres) reaches of stream, and were mostly located in moderate- to fast-flowing habitats (i.e. glide or run), although, at night, use of slower-flowing habitats (i.e. pools) increased. They also undertook longer-distance downstream movements during a period of increased streamflow. Incorporation of such information into management strategies has the potential to improve our capacity to maintain or re-instate the conditions required to conserve and restore Australian grayling populations.

Abstract:
Dissolved oxygen (DO) can be a strong predictor of intraspecific variation in morphology and physiology in fishes. In the African cichlid Pseudocrenilabrus multicolor victoriae Seegers, 1990, fish reared under low DO develop larger gills, deeper bodies, and larger, wider heads than full siblings reared under high DO, which could influence swim performance. In this study, we compared critical swim speed (Ucrit) and fast-start swimming in F1-generation fish from two field populations (one high and one low DO) of P. m. victoriae reared under high or low DO. There was no difference in Ucrit between populations or rearing treatments. However, females exhibited a lower Ucrit than males. In fast-start trials, low-DO-reared fish reacted faster (lower response latency) and used double bends more often than high-DO-reared fish, but there was no difference in maximum velocity or acceleration. Low-DO-reared fish might compensate for morphological differences by using double bends to achieve similar performance as high-DO siblings. These results suggest that divergent morphotypes of P. m. victoriae are capable of achieving the same level of performance under their home DO condition and highlights the importance of developmental plasticity in facilitating adaptive response to alternative environments.

Abstract:
AbstractCichlid fishes are a very diverse and species-rich family of teleost fishes that inhabit lakes and rivers of India, Africa, and South and Central America. Research has largely focused on East African cichlids of the Rift Lakes Tanganyika, Malawi, and Victoria that constitute the biodiversity hotspots of cichlid fishes. Here, we give an overview of the study system, research questions, and methodologies. Research on cichlid fishes spans many disciplines including ecology, evolution, physiology, genetics, development, and behavioral biology. In this review, we focus on a range of organismal traits, including coloration phenotypes, trophic adaptations, appendages like fins and scales, sensory systems, sex, brains, and behaviors. Moreover, we discuss studies on cichlid phylogenies, plasticity, and general evolutionary patterns, ranging from convergence to speciation rates and the proximate and ultimate mechanisms underlying these processes. From a methodological viewpoint, the last decade has brought great advances in cichlid fish research, particularly through the advent of affordable deep sequencing and advances in genetic manipulations. The ability to integrate across traits and research disciplines, ranging from developmental biology to ecology and evolution, makes cichlid fishes a fascinating research system.

Abstract:
Abstract The adaptive radiations of East African cichlid fish in the Great Lakes Victoria, Malawi, and Tanganyika are well known for their diversity and repeatedly evolved phenotypes. Convergent evolution of melanic horizontal stripes has been linked to a single locus harboring the gene agouti-related peptide 2 (agrp2). However, where and when the causal variants underlying this trait evolved and how they drove phenotypic divergence remained unknown. To test the alternative hypotheses of standing genetic variation versus de novo mutations (independently originating in each radiation), we searched for shared signals of genomic divergence at the agrp2 locus. Although we discovered similar signatures of differentiation at the locus level, the haplotypes associated with stripe patterns are surprisingly different. In Lake Malawi, the highest associated alleles are located within and close to the 5′ untranslated region of agrp2 and likely evolved through recent de novo mutations. In the younger Lake Victoria radiation, stripes are associated with two intronic regions overlapping with a previously reported cis-regulatory interval. The origin of these segregating haplotypes predates the Lake Victoria radiation because they are also found in more basal riverine and Lake Kivu species. This suggests that both segregating haplotypes were present as standing genetic variation at the onset of the Lake Victoria adaptive radiation with its more than 500 species and drove phenotypic divergence within the species flock. Therefore, both new (Lake Malawi) and ancient (Lake Victoria) allelic variation at the same locus fueled rapid and convergent phenotypic evolution.

Abstract:
But fish cognitive ecology did not begin in rivers and streams. Rather, one of the starting points for work on fish cognitive ecology was work done on the use of visual cues by homing pigeons. Prior to working with fish, Victoria Braithwaite helped to establish that homing pigeons rely not just on magnetic and olfactory cues but also on visual cues for successful return to their home loft. Simple, elegant experiments on homing established Victoria's ability to develop experimental manipulations to examine the role of visual cues in navigation by fish in familiar areas. This work formed the basis of a rich seam of work whereby a fish's ecology was used to propose hypotheses and predictions as to preferred cue use, and then cognitive abilities in a variety of fish species, from model systems (Atlantic salmon and sticklebacks) to the Panamanian Brachyraphis episcopi. Cognitive ecology in fish led to substantial work on fish pain and welfare, but was never left behind, with some of Victoria's last work addressed to determining the neural instantiation of cognitive variation.

Full text
Abstract:
To understand animal ecology, observation of wildlife in the natural habitat is essential, but particularly challenging in the underwater realm. Weakly electric fishes provide an excellent opportunity to overcome some of these challenges because they generate electric organ discharges (EODs) to sense their environment and to communicate, which can be detected non-invasively. We tracked the EOD and swimming activity of two species of mormyrid weakly electric fishes (Marcusenius victoriae and Petrocephalus degeni) over diel cycles in the laboratory, and we recorded EODs and environmental dissolved oxygen (DO) concentration and temperature over several months in a naturally hypoxic habitat in Uganda. Under laboratory conditions, both species showed increases of activity and exploration behavior that were closely synchronized to the onset of the dark phase. In the wild, fish preferred structurally complex habitats during the day, but dispersed toward open areas at night, presumably to forage and interact. Nocturnal increase of movement range coincided with diel declines in DO concentration to extremely low levels. The fact that fish showed pronounced nocturnal activity patterns in the laboratory and in the open areas of their habitat, but not under floating vegetation, indicates that light intensity exerts a direct effect on their activity. We hypothesize that being dark-active and tolerant to hypoxia increases the resistance of these fish against predators. This study establishes a new technology to record EODs in the field and provides a window into the largely unknown behavior of mormyrids in their natural habitat.

Abstract:
In this article I discuss a story told by the South Australian Ngarrindjeri Aboriginal elder, Aunty Hilda Wilson (nee Varcoe), about the time when, at not quite sixteen, she was sent from the Point Pearce Aboriginal Station to work in the Adelaide Hills, some 500 kilometres away, as a housekeeper for “one of Adelaide’s leading doctors”. Her secondment was part of a widespread practice in early and mid-twentieth century Australia of placing young Aboriginal women “of marriageable age” from missions and government reserves into domestic service. Consciously deploying Indigenous storytelling practices as pedagogy, Hilda Wilson recounted this episode in a number of distinct ways during the late 1990s and early 2000s. Across these iterations, each building on the other, she exhibited a personal resilience in her subjectivity, embedded in Indigenous knowledge systems of relationality, kin and work, which informed her agency and determination in a challenging situation in which she was both caring for a white socially-privileged family of five, while simultaneously grappling with the injustices of a state system of segregated indentured labour. Kirmayer and colleagues propose that “notions of resilience emerging from developmental psychology and psychiatry in recent years address the distinctive cultures, geographic and social settings, and histories of adversity of indigenous peoples”. Resilience is understood here as an ability to actively engage with traumatic change, involving the capacity to absorb stress and to transform in order to cope with it (Luthar et al.). Further to this, in an Indigenous context, Marion Kickett has found the capacity for resilience to be supported by three key factors: family connections, culture and belonging as well as notions of identity and history. In exploring the layers of this autobiographical story, I employ this extended psychological notion of resilience in both a domestic ambit as well as the broader social context for Indigenous people surviving a system of external domination. Additionally I consider the resilience Aunty Hilda demonstrates at a pivotal interlude between girlhood and womanhood within the trajectory of her overall long and productive life, and within an intergenerational history of resistance and accommodation. What is especially important about her storytelling is its refusal to be contained by the imaginary of the settler nation and its generic Aboriginal-female subject. She refuses victimhood while at the same time illuminating the mechanisms of injustice, hinting also at possibilities for alternative and more equitable relationships of family and work across cultural divides. Considered through this prism, resilience is, I suggest, also a quality firmly connected to ideas of Aboriginal cultural-sovereignty and standpoint and to, what Victoria Grieves has identified as, the Aboriginal knowledge value of sharing (25, 28, 45). Storytelling as Pedagogy The story I discuss was verbally recounted in a manner that Westphalen describes as “a continuation of Dreaming Stories”, functioning to educate and connect people and country (13-14). As MacGill et al. note, “the critical and transformative aspects of decolonising pedagogies emerge from storytelling and involve the gift of narrative and the enactment of reciprocity that occurs between the listener and the storyteller.” Hilda told me that as a child she was taught not to ask questions when listening to the stories of an Elder, and her own children were raised in this manner. Hilda's oldest daughter described this as a process involving patience, intrigue and surprise (Elva Wanganeen). Narratives unfold through nuance and repetition in a complexity of layers that can generate multiple levels of meaning over time. Circularity and recursivity underlie this pedagogy through which mnemonic devices are built so that stories become re-membered and inscribed on the body of the listener. When a perceived level of knowledge-transference has occurred, a narrator may elect to elaborate further, adding another detail that will often transform the story’s social, cultural, moral or political context. Such carefully chosen additional detail, however, might re-contextualise all that has gone before. As well as being embodied, stories are also emplaced, and thus most appropriately told in the Country where events occurred. (Here I use the Aboriginal English term “Country” which encompasses home, clan estate, and the powerful complex of spiritual, animate and inanimate forces that bind people and place.) Hilda Wilson’s following account of her first job as a housekeeper for “one of Adelaide’s leading doctors”, Dr Frank Swann, provides an illustration of how she expertly uses traditional narrative forms of incrementally structured knowledge transmission within a cross-cultural setting to tell a story that expresses practices of resilience as resistance and transformation at its core. A “White Doctor” Story: The First Layer Aunty Hilda first told me this story when we were winding along the South Eastern Freeway through the Adelaide hills between Murray Bridge and Mount Barker, in 1997, on our way home to Adelaide from a trip to Camp Coorong, the Ngarrindjeri cultural education centre co-founded by her granddaughter. She was then 86 years old. Ahead of us, the profile of Mt Lofty rose out of the plains and into view. The highest peak in the Mount Lofty ranges, Yurrebilla, as it is known to Kaurna Aboriginal people, or Mt Lofty, has been an affluent enclave of white settlement for Adelaide’s moneyed elite since early colonial times. Being in place, or in view of place, provided the appropriate opportunity for her to tell me the story. It belongs to a group of stories that during our initial period of working together changed little over time until one day two years later she an added contextual detail which turned it inside out. Hilda described the doctor’s spacious hill-top residence, and her responsibilities of caring for Dr Swann’s invalid wife (“an hysteric who couldn't do anything for herself”), their twin teenage boys (who attended private college in the city) along with another son and younger daughter living at home (pers. com. Hilda Wilson). Recalling the exhilaration of looking down over the sparkling lights of Adelaide at night from this position of apparent “privilege” on the summit, she related this undeniably as a success story, justifiably taking great pride in her achievements as a teenager, capable of stepping into the place of the non-Indigenous doctor's wife in running the large and demanding household. Successfully undertaking a wide range of duties employed in the care of a family, including the disabled mother, she is an active participant crucial to the lives of all in the household, including to the work of the doctor and the twin boys in private education. Hilda recalled that Mrs Swann was unable to eat without her assistance. As the oldest daughter of a large family Hilda had previously assisted in caring for her younger siblings. Told in this way, her account collapses social distinctions, delineating a shared social and physical space, drawing its analytic frame from an Indigenous ethos of subjectivity, relationality, reciprocity and care. Moreover Hilda’s narrative of domestic service demonstrates an assertion of agency that resists colonial and patriarchal hegemony and inverts the master/mistress-servant relationship, one she firmly eschews in favour of the self-affirming role of the lady of the house. (It stands in contrast to the abuse found in other accounts for example Read, Tucker, Kartinyeri. Often the key difference was a continuity of family connections and ongoing family support.) Indeed the home transformed into a largely feminised and cross-culturalised space in which she had considerable agency and responsibility when the doctor was absent. Hilda told me this story several times in much the same way during our frequent encounters over the next two years. Each telling revealed further details that fleshed a perspective gained from what Patricia Hill Collins terms an “epistemic privilege” via her “outsider-within status” of working within a white household, lending an understanding of its social mechanisms (12-15). She also stressed the extent of her duty of care in upholding the family’s well-being, despite the work at times being too burdensome. The Second Version: Coming to Terms with Intersecting Oppressions Later, as our relationship developed and deepened, when I began to record her life-narrative as part of my doctoral work, she added an unexpected detail that altered its context completely: It was all right except I slept outside in a tin shed and it was very cold at night. Mount Lofty, by far the coldest part of Adelaide, frequently experiences winter maximum temperatures of two or three degrees and often light snowfalls. This skilful reframing draws on Indigenous storytelling pedagogy and is expressly used to invite reflexivity, opening questions that move the listener from the personal to the public realm in which domestic service and the hegemony of the home are pivotal in coming to terms with the overlapping historical oppressions of class, gender, race and nation. Suddenly we witness her subjectivity starkly shift from one self-defined and allied with an equal power relationship – or even of dependency reversal cast as “de-facto doctor's wife” – to one diminished by inequity and power imbalance in the outsider-defined role of “mistreated servant”. The latter was signalled by the dramatic addition of a single signifying detail as a decoding device to a deeper layer of meaning. In this parallel stratum of the story, Hilda purposefully brings into relief the politics in which “the private domain of women's housework intersected with the public domain of governmental social engineering policies” (Haskins 4). As Aileen Moreton-Robinson points out, what for White Australia was cheap labour and a civilising mission, for Indigenous women constituted stolen children and slavery. Protection and then assimilation were government policies under which Indigenous women grew up. (96) Hilda was sent away from her family to work in 1927 by the universally-feared Sister Pearl McKenzie, a nurse who too-zealously (Katinyeri, Ngarrindjeri Calling, 23) oversaw the Chief Protector’s policies of “training” Aboriginal children from the South Australian missions in white homes once they reached fourteen (Haebich, 316—20). Indeed many prominent Adelaide hills’ families benefited from Aboriginal labour under this arrangement. Hilda explained her struggle with the immense cultural dislocation that removal into domestic service entailed, a removal her grandfather William Rankine had travelled from Raukkan to Government House to protest against less than a decade earlier (The Register December 21, 1923). This additional layer of story also illuminates Hilda’s capacity for resilience and persistence in finding a way forward through the challenge of her circumstances (Luthar et al.), drawing on her family networks and sense of personhood (Kickett). Hilda related that her father visited her at Mount Lofty twice, though briefly, on his way to shearing jobs in the south-east of the state. “He said it was no good me living like this,” she stated. Through his active intervention, reinforcement was requested and another teenager from Point Pearce, Hilda’s future husband’s cousin, Annie Sansbury, soon arrived to share the workload. But, Hilda explained, the onerous expectations coupled with the cultural segregation of retiring to the tin shed quickly became too much for Annie, who stayed only three months, leaving Hilda coping again alone, until her father applied additional pressure for a more suitable placement to be found for his daughter. In her next position, working for the family of a racehorse trainer, Hilda contentedly shared the bedroom with the small boy for whom she cared, and not long after returned to Point Pearce where she married Robert Wilson and began a family of her own. Gendered Resilience across Cultural Divides Hilda explicitly speaks into these spaces to educate me, because all but a few white women involved have remained silent about their complicity with state sanctioned practices which exploited Indigenous labour and removed children from their families through the policies of protection and assimilation. For Indigenous women, speaking out was often fraught with the danger of a deeper removal from family and Country, even of disappearance. Victoria Haskins writes extensively of two cases in New South Wales where young Aboriginal women whose protests concerning their brutal treatment at the hands of white employers, resulted in their wrongful and prolonged committal to mental health and other institutions (147-52, 228-39). In the indentured service of Indigenous women it is possible to see oppression operating through Eurocentric ideologies of race, class and gender, in which Indigenous women were assumed to take on, through displacement, the more oppressed role of white women in pre-second world war non-Aboriginal Australian society. The troubling silent shadow-figure of the “doctor’s wife” indeed provides a haunting symbol of - and also a forceful rebellion against – the docile upper middle-class white femininity of the inter-war era. Susan Bordo has argued that that “the hysteric” is archetypal of a discourse of ‘pathology as embodied protest’ in which the body may […] be viewed as a surface on which conventional constructions of femininity are exposed starkly to view in extreme or hyperliteral form. (20) Mrs Swann’s vulnerability contrasts markedly with the strength Hilda expresses in coping with a large family, emanating from a history of equitable gender relations characteristic of Ngarrindjeri society (Bell). The intersection of race and gender, as Marcia Langton contends “continues to require deconstruction to allow us to decolonise our consciousness” (54). From Hilda’s brief description one grasps a relationship resonant with that between the protagonists in Tracy Moffat's Night Cries, (a response to the overt maternalism in the film Jedda) in which the white mother finds herself utterly reliant on her “adopted” Aboriginal daughter at the end of her life (46-7). Resilience and Survival The different versions of story Hilda deploys, provide a pedagogical basis to understanding the broader socio-political framework of her overall life narrative in which an ability to draw on the cultural continuity of the past to transform the future forms an underlying dynamic. This demonstrated capacity to meet the challenging conditions thrown up by the settler-colonial state has its foundations in the connectivity and cultural strength sustained generationally in her family. Resilience moves from being individually to socially determined, as in Kickett’s model. During the onslaught of dispossession, following South Australia’s 1836 colonial invasion, Ngarrindjeri were left near-starving and decimated from introduced diseases. Pullume (c1808-1888), the rupuli (elected leader of the Ngarrindjeri Tendi, or parliament), Hilda’s third generation great-grandfather, decisively steered his people through the traumatic changes, eventually negotiating a middle-path after the Point McLeay Mission was established on Ngarrindjeri country in 1859 (Jenkin, 59). Pullume’s granddaughter, the accomplished, independent-thinking Ellen Sumner (1842—1925), played an influential educative role during Hilda’s youth. Like other Ngarrindjeri women in her lineage, Ellen Sumner was skilled in putari practice (female doctor) and midwifery culture that extended to a duty of care concerning women and children (teaching her “what to do and what not to do”), which I suggest is something Hilda herself drew from when working with the Swann family. Hilda’s mother and aunties continued aspects of the putari tradition, attending births and giving instruction to women in the community (Bell, 171, Hughes Grandmother, 52-4). As mentioned earlier, when the South Australian government moved to introduce The Training of Children Act (SA) Hilda’s maternal grandfather William Rankine campaigned vigorously against this, taking a petition to the SA Governor in December 1923 (Haebich, 315-19). As with Aunty Hilda, William Rankine used storytelling as a method to draw public attention to the inequities of his times in an interview with The Register which drew on his life-narrative (Hughes, My Grandmother, 61). Hilda’s father Wilfred Varcoe, a Barngarrla-Wirrungu man, almost a thousand kilometres away from his Poonindie birthplace, resisted assimilation by actively pursuing traditional knowledge networks using his mobility as a highly sought after shearer to link up with related Elders in the shearing camps, (and as we saw to inspect the conditions his daughter was working under at Mt Lofty). The period Hilda spent as a servant to white families to be trained in white ways was in fact only a brief interlude in a long life in which family connections, culture and belonging (Kickett) served as the backbone of her resilience and resistance. On returning to the Point Pearce Mission, Hilda successfully raised a large family and activated a range of community initiatives that fostered well-being. In the 1960s she moved to Adelaide, initially as the sole provider of her family (her husband later followed), to give her younger children better educational opportunities. Working with Aunty Gladys Elphick OBE through the Council of Aboriginal Women, she played a foundational role in assisting other Aboriginal women establish their families in the city (Mattingly et al., 154, Fisher). In Adelaide, Aunty Hilda became an influential, much loved Elder, living in good health to the age of ninety-six years. The ability to survive changing circumstances, to extend care over and over to her children and Elders along with qualities of leadership, determination, agency and resilience have passed down through her family, several of whom have become successful in public life. These include her great-grandson and former AFL football player, Michael O’Loughlin, her great-nephew Adam Goodes and her-grand-daughter, the cultural weaver Aunty Ellen Trevorrow. Arguably, resilience contributes to physical as well as cultural longevity, through caring for the self and others. Conclusion This story demonstrates how sociocultural dimensions of resilience are contextualised in practices of everyday lives. We see this in the way that Aunty Hilda Wilson’s self-narrated story resolutely defies attempts to know, subjugate and categorise, operating instead in accord with distinctively Aboriginal expressions of gender and kinship relations that constitute an Aboriginal sovereignty. Her storytelling activates a revision of collective history in ways that valorise Indigenous identity (Kirmayer et al.). Her narrative of agency and personal achievement, one that has sustained her through life, interacts with the larger narrative of state-endorsed exploitation, diffusing its power and exposing it to wider moral scrutiny. Resilience in this context is inextricably entwined with practices of cultural survival and resistance developed in response to the introduction of government policies and the encroachment of settlers and their world. We see resilience too operating across Hilda Wilson’s family history, and throughout her long life. The agency and strategies displayed suggest alternative realities and imagine other, usually more equitable, possible worlds. References Bell, Diane.

Abstract:
IntroductionCirque du Soleil, the largest live entertainment company in the world, has eight standing shows in Las Vegas alone, KÀ, Love, Mystère, Zumanity, Believe, Michael Jackson ONE, Zarkana and O. Close to 150 million spectators have seen Cirque du Soleil shows since the company’s beginnings in 1984 and it is estimated that over 15 million spectators will see a Cirque du Soleil show in 2014 (Cirque du Soleil). The Cirque du Soleil concept of circus as a form of theatre, with simple, often archetypal, narrative arcs conveyed without words, virtuoso physicality with the circus artists presented as characters in a fictional world, cutting-edge lighting and visuals, extraordinary innovative staging, and the uptake of new technology for special effects can all be linked back to an early form of circus which is sometimes termed illegitimate circus. In the late 18th century and early 19th century, in the age of Romanticism, only two theatres in London, Covent Garden and Drury Lane, plus the summer theatre in the Haymarket, had royal patents allowing them to produce plays or text-based productions, and these were considered legitimate theatres. (These theatres retained this monopoly until the Theatre Regulation Act of 1843; Saxon 301.) Other circuses and theatres such as Astley’s Amphitheatre, which were precluded from performing text-based works by the terms of their licenses, have been termed illegitimate (Moody 1). Perversely, the effect of licensing venues in this way, instead of having the desired effect of enshrining some particular forms of expression and “casting all others beyond the cultural pale,” served instead to help to cultivate a different kind of theatrical landscape, “a theatrical terrain with a new, rich and varied dramatic ecology” (Reed 255). A fundamental change to the theatrical culture of London took place, and pivotal to “that transformation was the emergence of an illegitimate theatrical culture” (Moody 1) with circus at its heart. An innovative and different form of performance, a theatre of the body, featuring spectacle and athleticism emerged, with “a sensuous, spectacular aesthetic largely wordless except for the lyrics of songs” (Bratton 117).This writing sets out to explore some of the strong parallels between the aesthetic that emerged in this early illegitimate circus and the aesthetic of the Montreal-based, multi-billion dollar entertainment empire of Cirque du Soleil. Although it is not fighting against legal restrictions and can in no way be considered illegitimate, the circus of Cirque du Soleil can be seen to be the descendant of the early circus entrepreneurs and their illegitimate aesthetic which arose out of the desire to find ways to continue to attract audiences to their shows in spite of the restrictions of the licenses granted to them. BackgroundCircus has served as an inspiration for many innovatory theatre productions including Peter Brook’s Midsummer Night’s Dream (1970) and Tom Stoppard’s Jumpers (1972) as well as the earlier experiments of Meyerhold, Eisenstein, Mayakovsky and other Soviet directors of the 1920’s (Saxon 299). A. H. Saxon points out, however, that the relationship between circus and theatre is a long-standing one that begins in the late 18th century and the early 19th century, when circus itself was theatre (Saxon 299).Modern circus was founded in London in 1768 by an ex-cavalryman and his wife, Philip and Patty Astley, and consisted of spectacular stunt horse riding taking place in a ring, with acts from traditional fairs such as juggling, acrobatics, clowning and wire-walking inserted to cover the changeovers between riding acts. From the very first shows entry was by paid ticket only and the early history of circus was driven by innovative, risk-taking entrepreneurs such as Philip Astley, who indeed built so many new amphitheatres for his productions that he became known as Amphi-Philip (Jando). After years of legal tussles with the authorities concerning the legal status of this new entertainment, a limited license was finally granted in 1783 for Astley’s Amphitheatre. This license precluded the performing of plays, anything text-based, or anything which had a script that resembled a play. Instead the annual license granted allowed only for “public dancing and music” and “other public entertainments of like kind” (St. Leon 9).Corporeal Dramaturgy and TextIn the face of the ban on scripted text, illegitimate circus turned to the human body and privileged it as a means of dramatic expression. A resultant dramaturgy focusing on the expressive capabilities of the performers’ bodies emerged. “The primacy of rhetoric and the spoken word in legitimate drama gave way […] to a corporeal dramaturgy which privileged the galvanic, affective capacity of the human body as a vehicle of dramatic expression” (Moody 83). Moody proposes that the “iconography of illegitimacy participated in a broader cultural and scientific transformation in which the human body began to be understood as an eloquent compendium of visible signs” (83). Even though the company has the use of text and dramatic dialogue freely available to it, Cirque du Soleil, shares this investment in the bodies of the performers and their “galvanic, affective capacity” (83) to communicate with the audience directly without the use of a scripted text, and this remains a constant between the two forms of circus. Robert Lepage, the director of two Cirque du Soleil shows, KÀ (2004) and more recently Totem (2010), speaking about KÀ in 2004, said, “We wanted it to be an epic story told not with the use of words, but with the universal language of body movement” (Lepage cited in Fink).In accordance with David Graver’s system of classifying performers’ bodies, Cirque du Soleil’s productions most usually present performers’ ‘character bodies’ in which the performers are understood by spectators to be playing fictional roles or characters (Hurley n/p) and this was also the case with illegitimate circus which right from its very beginnings presented its performers within narratives in which the performers are understood to be playing characters. In Cirque du Soleil’s shows, as with illegitimate circus, this presentation of the performers’ character bodies is interspersed with acts “that emphasize the extraordinary training and physical skill of the performers, that is which draw attention to the ‘performer body’ but always within the context of an overall narrative” (Fricker n.p.).Insertion of Vital TextAfter audience feedback, text was eventually added into KÀ (2004) in the form of a pre-recorded prologue inserted to enable people to follow the narrative arc, and in the show Wintuk (2007) there are tales that are sung by Jim Comcoran (Leroux 126). Interestingly early illegitimate circus creators, in their efforts to circumvent the ban on using dramatic dialogue, often inserted text into their performances in similar ways to the methods Cirque du Soleil chose for KÀ and Wintuk. Illegitimate circus included dramatic recitatives accompanied by music to facilitate the following of the storyline (Moody 28) in the same way that Cirque du Soleil inserted a pre-recorded prologue to KÀ to enable audience members to understand the narrative. Performers in illegitimate circus often conveyed essential information to the audience as lyrics of songs (Bratton 117) in the same way that Jim Comcoran does in Wintuk. Dramaturgical StructuresAstley from his very first circus show in 1768 began to set his equestrian stunts within a narrative. Billy Button’s Ride to Brentford (1768), showed a tailor, a novice rider, mounting backwards, losing his belongings and being thrown off the horse when it bucks. The act ends with the tailor being chased around the ring by his horse (Schlicke 161). Early circus innovators, searching for dramaturgy for their shows drew on contemporary warfare, creating vivid physical enactments of contemporary battles. They also created a new dramatic form known as Hippodramas (literally ‘horse dramas’ from hippos the Attic Greek for Horse), a hybridization of melodrama and circus featuring the trick riding skills of the early circus pioneers. The narrative arcs chosen were often archetypal or sourced from well-known contemporary books or poems. As Moody writes, at the heart of many of these shows “lay an archetypal narrative of the villainous usurper finally defeated” (Moody 30).One of the first hippodramas, The Blood Red Knight, opened at Astley’s Amphitheatre in 1810.Presented in dumbshow, and interspersed with grand chivalric processions, the show featured Alphonso’s rescue of his wife Isabella from her imprisonment and forced marriage to the evil knight Sir Rowland and concluded with the spectacular, fiery destruction of the castle and Sir Rowland’s death. (Moody 69)Another later hippodrama, The Spectre Monarch and his Phantom Steed, or the Genii Horseman of the Air (1830) was set in China where the rightful prince was ousted by a Tartar usurper who entered into a pact with the Spectre Monarch and received,a magic ring, by aid of which his unlawful desires were instantly gratified. Virtue, predictably won out in the end, and the discomforted villain, in a final settling of accounts with his dread master was borne off through the air in a car of fire pursued by Daemon Horsemen above THE GREAT WALL OF CHINA. (Saxon 303)Karen Fricker writes of early Cirque du Soleil shows that “while plot is doubtless too strong a word, each of Cirque’s recent shows has a distinct concept or theme, that is urbanity for Saltimbanco; nomadism in Varekai (2002) and humanity’s clownish spirit for Corteo (2005), and tend to follow the same very basic storyline, which is not narrated in words but suggested by the staging that connects the individual acts” (Fricker n/p). Leroux describes the early Cirque du Soleil shows as following a “proverbial and well-worn ‘collective transformation trope’” (Leroux 122) whilst Peta Tait points out that the narrative arc of Cirque du Soleil “ might be summarized as an innocent protagonist, often female, helped by an older identity, seemingly male, to face a challenging journey or search for identity; more generally, old versus young” (Tait 128). However Leroux discerns an increasing interest in narrative devices such as action and plot in Cirque du Soleil’s Las Vegas productions (Leroux 122). Fricker points out that “with KÀ, what Cirque sought – and indeed found in Lepage’s staging – was to push this storytelling tendency further into full-fledged plot and character” (Fricker n/p). Telling a story without words, apart from the inserted prologue, means that the narrative arc of Kà is, however, very simple. A young prince and princess, twins in a mythical Far Eastern kingdom, are separated when a ceremonial occasion is interrupted by an attack by a tribe of enemy warriors. A variety of adventures follow, most involving perilous escapes from bad guys with flaming arrows and fierce-looking body tattoos. After many trials, a happy reunion arrives. (Isherwood)This increasing emphasis on developing a plot and a narrative arc positions Cirque as moving closer in dramaturgical aesthetic to illegitimate circus.Visual TechnologiesTo increase the visual excitement of its shows and compensate for the absence of spoken dialogue, illegitimate circus in the late 18th and early 19th century drew on contemporaneous and emerging visual technologies. Some of the new visual technologies that Astley’s used have been termed pre-cinematic, including the panorama (or diorama as it is sometimes called) and “the phantasmagoria and other visual machines… [which] expanded the means through which an audience could be addressed” (O’Quinn, Governance 312). The panorama or diorama ran in the same way that a film runs in an analogue camera, rolling between vertical rollers on either side of the stage. In Astley’s production The Siege and Storming of Seringapatam (1800) he used another effect almost equivalent to a modern day camera zoom-in by showing scenic back drops which, as they moved through time, progressively moved geographically closer to the battle. This meant that “the increasing enlargement of scale-each successive scene has a smaller geographic space-has a telescopic event. Although the size of the performance space remains constant, the spatial parameters of the spectacle become increasingly magnified” (O’Quinn, Governance 345). In KÀ, Robert Lepage experiments with “cinematographic stage storytelling on a very grand scale” (Fricker n.p.). A KÀ press release (2005) from Cirque du Soleil describes the show “as a cinematic journey of aerial adventure” (Cirque du Soleil). Cirque du Soleil worked with ground-breaking visual technologies in KÀ, developing an interactive projected set. This involves the performers controlling what happens to the projected environment in real time, with the projected scenery responding to their movements. The performers’ movements are tracked by an infra-red sensitive camera above the stage, and by computer software written by Interactive Production Designer Olger Förterer. “In essence, what we have is an intelligent set,” says Förterer. “And everything the audience sees is created by the computer” (Cirque du Soleil).Contemporary Technology Cutting edge technologies, many of which came directly from contemporaneous warfare, were introduced into the illegitimate circus performance space by Astley and his competitors. These included explosions using redfire, a new military explosive that combined “strontia, shellac and chlorate of potash, [which] produced […] spectacular flame effects” (Moody 28). Redfire was used for ‘blow-ups,’ the spectacular explosions often occurring at the end of the performance when the villain’s castle or hideout was destroyed. Cirque du Soleil is also drawing on contemporary military technology for performance projects. Sparked: A Live interaction between Humans and Quadcopters (2014) is a recent short film released by Cirque du Soleil, which features the theatrical use of drones. The new collaboration between Cirque du Soleil, ETH Zurich and Verity Studios uses 10 quadcopters disguised as animated lampshades which take to the air, “carrying out the kinds of complex synchronized dance manoeuvres we usually see from the circus' famed acrobats” (Huffington Post). This shows, as with early illegitimate circus, the quick theatrical uptake of contemporary technology originally developed for use in warfare.Innovative StagingArrighi writes that the performance space that Astley developed was a “completely new theatrical configuration that had not been seen in Western culture before… [and] included a circular ring (primarily for equestrian performance) and a raised theatre stage (for pantomime and burletta)” (177) joined together by ramps that were large enough and strong enough to allow horses to be ridden over them during performances. The stage at Astley’s Amphitheatre was said to be the largest in Europe measuring over 130 feet across. A proscenium arch was installed in 1818 which could be adjusted in full view of the audience with the stage opening changing anywhere in size from forty to sixty feet (Saxon 300). The staging evolved so that it had the capacity to be multi-level, involving “immense [moveable] platforms or floors, rising above each other, and extending the whole width of the stage” (Meisel 214). The ability to transform the stage by the use of draped and masked platforms which could be moved mechanically, proved central to the creation of the “new hybrid genre of swashbuckling melodramas on horseback, or ‘hippodramas’” (Kwint, Leisure 46). Foot soldiers and mounted cavalry would fight their way across the elaborate sets and the production would culminate with a big finale that usually featured a burning castle (Kwint, Legitimization 95). Cirque du Soleil’s investment in high-tech staging can be clearly seen in KÀ. Mark Swed writes that KÀ is, “the most lavish production in the history of Western theatre. It is surely the most technologically advanced” (Swed). With a production budget of $165 million (Swed), theatre designer Michael Fisher has replaced the conventional stage floor with two huge moveable performance platforms and five smaller platforms that appear to float above a gigantic pit descending 51 feet below floor level. One of the larger platforms is a tatami floor that moves backwards and forwards, the other platform is described by the New York Times as being the most thrilling performer in the show.The most consistently thrilling performer, perhaps appropriately, isn't even human: It's the giant slab of machinery that serves as one of the two stages designed by Mark Fisher. Here Mr. Lepage's ability to use a single emblem or image for a variety of dramatic purposes is magnified to epic proportions. Rising and falling with amazing speed and ease, spinning and tilting to a full vertical position, this huge, hydraulically powered game board is a sandy beach in one segment, a sheer cliff wall in another and a battleground, viewed from above, for the evening's exuberantly cinematic climax. (Isherwood)In the climax a vertical battle is fought by aerialists fighting up and down the surface of the sand stone cliff with defeated fighters portrayed as tumbling down the surface of the cliff into the depths of the pit below. Cirque du Soleil’s production entitled O, which phonetically is the French word eau meaning water, is a collaboration with director Franco Dragone that has been running at Las Vegas’ Bellagio Hotel since 1998. O has grossed over a billion dollars since it opened in 1998 (Sylt and Reid). It is an aquatic circus or an aquadrama. In 1804, Charles Dibdin, one of Astley’s rivals, taking advantage of the nearby New River, “added to the accoutrements of the Sadler’s Wells Theatre a tank three feet deep, ninety feet long and as wide as twenty-four feet which could be filled with water from the New River” (Hays and Nickolopoulou 171) Sadler’s Wells presented aquadramas depicting many reconstructions of famous naval battles. One of the first of these was The Siege of Gibraltar (1804) that used “117 ships designed by the Woolwich Dockyard shipwrights and capable of firing their guns” (Hays and Nickolopoulou 5). To represent the drowning Spanish sailors saved by the British, “Dibdin used children, ‘who were seen swimming and affecting to struggle with the waves’”(5).O (1998) is the first Cirque production to be performed in a proscenium arch theatre, with the pool installed behind the proscenium arch. “To light the water in the pool, a majority of the front lighting comes from a subterranean light tunnel (at the same level as the pool) which has eleven 4" thick Plexiglas windows that open along the downstage perimeter of the pool” (Lampert-Greaux). Accompanied by a live orchestra, performers dive into the 53 x 90 foot pool from on high, they swim underwater lit by lights installed in the subterranean light tunnel and they also perform on perforated platforms that rise up out of the water and turn the pool into a solid stage floor. In many respects, Cirque du Soleil can be seen to be the inheritors of the spectacular illegitimate circus of the 18th and 19th Century. The inheritance can be seen in Cirque du Soleil’s entrepreneurial daring, the corporeal dramaturgy privileging the affective power of the body over the use of words, in the performers presented primarily as character bodies, and in the delivering of essential text either as a prologue or as lyrics to songs. It can also be seen in Cirque du Soleil’s innovative staging design, the uptake of military based technology and the experimentation with cutting edge visual effects. Although re-invigorating the tradition and creating spectacular shows that in many respects are entirely of the moment, Cirque du Soleil’s aesthetic roots can be clearly seen to draw deeply on the inheritance of illegitimate circus.ReferencesBratton, Jacky. “Romantic Melodrama.” The Cambridge Companion to British Theatre 1730-1830.

Abstract:
Special Care Notice This article contains images of deceased people that might cause sadness or distress to Aboriginal and Torres Strait Islander readers. Introduction Like many cities, Perth was founded on wetlands that have been integral to its history and culture (Seddon 226–32). However, in order to promote a settlement agenda, early mapmakers sought to erase the city’s wetlands from cartographic depictions (Giblett, Cities). Since the colonial era, inner-Perth’s swamps and lakes have been drained, filled, significantly reduced in size, or otherwise reclaimed for urban expansion (Bekle). Not only have the swamps and lakes physically disappeared, the memories of their presence and influence on the city’s development over time are also largely forgotten. What was the site of Perth, specifically its wetlands, like before British settlement? In 2014, an interdisciplinary team at Edith Cowan University developed a digital visualisation process to re-imagine Perth prior to colonisation. This was based on early maps of the Swan River Colony and a range of archival information. The images depicted the city’s topography, hydrology, and vegetation and became the centerpiece of a physical exhibition entitled Re-imagining Perth’s Lost Wetlands and a virtual exhibition hosted by the Western Australian Museum. Alongside historic maps, paintings, photographs, and writings, the visual reconstruction of Perth aimed to foster appreciation of the pre-settlement environment—the homeland of the Whadjuck Nyoongar, or Bibbulmun, people (Carter and Nutter). The exhibition included the narrative of Fanny Balbuk, a Nyoongar woman who voiced her indignation over the “usurping of her beloved home ground” (Bates, The Passing 69) by flouting property lines and walking through private residences to reach places of cultural significance. Beginning with Balbuk’s story and the digital tracing of her walking route through colonial Perth, this article discusses the project in the context of contemporary pressures on the city’s extant wetlands. The re-imagining of Perth through historically, culturally, and geographically-grounded digital visualisation approaches can inspire the conservation of its wetlands heritage. Balbuk’s Walk through the City For many who grew up in Perth, Fanny Balbuk’s perambulations have achieved legendary status in the collective cultural imagination. In his memoir, David Whish-Wilson mentions Balbuk’s defiant walks and the lighting up of the city for astronaut John Glenn in 1962 as the two stories that had the most impact on his Perth childhood. From Gordon Stephenson House, Whish-Wilson visualises her journey in his mind’s eye, past Government House on St Georges Terrace (the main thoroughfare through the city centre), then north on Barrack Street towards the railway station, the site of Lake Kingsford where Balbuk once gathered bush tucker (4). He considers the footpaths “beneath the geometric frame of the modern city […] worn smooth over millennia that snake up through the sheoak and marri woodland and into the city’s heart” (Whish-Wilson 4). Balbuk’s story embodies the intertwined culture and nature of Perth—a city of wetlands. Born in 1840 on Heirisson Island, Balbuk (also known as Yooreel) (Figure 1) had ancestral bonds to the urban landscape. According to Daisy Bates, writing in the early 1900s, the Nyoongar term Matagarup, or “leg deep,” denotes the passage of shallow water near Heirisson Island where Balbuk would have forded the Swan River (“Oldest” 16). Yoonderup was recorded as the Nyoongar name for Heirisson Island (Bates, “Oldest” 16) and the birthplace of Balbuk’s mother (Bates, “Aboriginal”). In the suburb of Shenton Park near present-day Lake Jualbup, her father bequeathed to her a red ochre (or wilgi) pit that she guarded fervently throughout her life (Bates, “Aboriginal”).Figure 1. Group of Aboriginal Women at Perth, including Fanny Balbuk (far right) (c. 1900). Image Credit: State Library of Western Australia (Image Number: 44c). Balbuk’s grandparents were culturally linked to the site. At his favourite camp beside the freshwater spring near Kings Park on Mounts Bay Road, her grandfather witnessed the arrival of Lieutenant-Colonel Frederick Irwin, cousin of James Stirling (Bates, “Fanny”). In 1879, colonial entrepreneurs established the Swan Brewery at this significant locale (Welborn). Her grandmother’s gravesite later became Government House (Bates, “Fanny”) and she protested vociferously outside “the stone gates guarded by a sentry [that] enclosed her grandmother’s burial ground” (Bates, The Passing 70). Balbuk’s other grandmother was buried beneath Bishop’s Grove, the residence of the city’s first archibishop, now Terrace Hotel (Bates, “Aboriginal”). Historian Bob Reece observes that Balbuk was “the last full-descent woman of Kar’gatta (Karrakatta), the Bibbulmun name for the Mount Eliza [Kings Park] area of Perth” (134). According to accounts drawn from Bates, her home ground traversed the area between Heirisson Island and Perth’s north-western limits. In Kings Park, one of her relatives was buried near a large, hollow tree used by Nyoongar people like a cistern to capture water and which later became the site of the Queen Victoria Statue (Bates, “Aboriginal”). On the slopes of Mount Eliza, the highest point of Kings Park, at the western end of St Georges Terrace, she harvested plant foods, including zamia fruits (Macrozamia riedlei) (Bates, “Fanny”). Fanny Balbuk’s knowledge contributed to the native title claim lodged by Nyoongar people in 2006 as Bennell v. State of Western Australia—the first of its kind to acknowledge Aboriginal land rights in a capital city and part of the larger Single Nyoongar Claim (South West Aboriginal Land and Sea Council et al.). Perth’s colonial administration perceived the city’s wetlands as impediments to progress and as insalubrious environments to be eradicated through reclamation practices. For Balbuk and other Nyoongar people, however, wetlands were “nourishing terrains” (Rose) that afforded sustenance seasonally and meaning perpetually (O’Connor, Quartermaine, and Bodney). Mary Graham, a Kombu-merri elder from Queensland, articulates the connection between land and culture, “because land is sacred and must be looked after, the relation between people and land becomes the template for society and social relations. Therefore all meaning comes from land.” Traditional, embodied reliance on Perth’s wetlands is evident in Bates’ documentation. For instance, Boojoormeup was a “big swamp full of all kinds of food, now turned into Palmerston and Lake streets” (Bates, “Aboriginal”). Considering her cultural values, Balbuk’s determination to maintain pathways through the increasingly colonial Perth environment is unsurprising (Figure 2). From Heirisson Island: a straight track had led to the place where once she had gathered jilgies [crayfish] and vegetable food with the women, in the swamp where Perth railway station now stands. Through fences and over them, Balbuk took the straight track to the end. When a house was built in the way, she broke its fence-palings with her digging stick and charged up the steps and through the rooms. (Bates, The Passing 70) One obstacle was Hooper’s Fence, which Balbuk broke repeatedly on her trips to areas between Kings Park and the railway station (Bates, “Hooper’s”). Her tenacious commitment to walking ancestral routes signifies the friction between settlement infrastructure and traditional Nyoongar livelihood during an era of rapid change. Figure 2.

Project Background and Approach Inspired by Fanny Balbuk’s story, Re-imagining Perth’s Lost Wetlands began as an Australian response to the Mannahatta Project. Founded in 1999, that project used spatial analysis techniques and mapping software to visualise New York’s urbanised Manhattan Island—or Mannahatta as it was called by indigenous people—in the early 1600s (Sanderson). Based on research into the island’s original biogeography and the ecological practices of Native Americans, Mannahatta enabled the public to “peel back” the city’s strata, revealing the original composition of the New York site. The layers of visuals included rich details about the island’s landforms, water systems, and vegetation. Mannahatta compelled Rod Giblett, a cultural researcher at Edith Cowan University, to develop an analogous model for visualising Perth circa 1829. The idea attracted support from the City of Perth, Landgate, and the University. Using stories, artefacts, and maps, the team—comprising a cartographer, designer, three-dimensional modelling expert, and historical researchers—set out to generate visualisations of the landscape at the time of British colonisation. Nyoongar elder Noel Nannup approved culturally sensitive material and contributed his perspective on Aboriginal content to include in the exhibition. The initiative’s context remains pressing. In many ways, Perth has become a template for development in the metropolitan area (Weller). While not unusual for a capital, the rate of transformation is perhaps unexpected in a city less than 200 years old (Forster). There also remains a persistent view of existing wetlands as obstructions to progress that, once removed, are soon forgotten (Urban Bushland Council). Digital visualisation can contribute to appreciating environments prior to colonisation but also to re-imagining possibilities for future human interactions with land, water, and space. Despite the rapid pace of change, many Perth area residents have memories of wetlands lost during their lifetimes (for example, Giblett, Forrestdale). However, as the clearing and drainage of the inner city occurred early in settlement, recollections of urban wetlands exist exclusively in historical records. In 1935, a local correspondent using the name “Sandgroper” reminisced about swamps, connecting them to Perth’s colonial heritage: But the Swamps were very real in fact, and in name in the [eighteen-] Nineties, and the Perth of my youth cannot be visualised without them. They were, of course, drying up apace, but they were swamps for all that, and they linked us directly with the earliest days of the Colony when our great-grandparents had founded this City of Perth on a sort of hog's-back, of which Hay-street was the ridge, and from which a succession of streamlets ran down its southern slope to the river, while land locked to the north of it lay a series of lakes which have long since been filled to and built over so that the only evidence that they have ever existed lies in the original street plans of Perth prepared by Roe and Hillman in the early eighteen-thirties. A salient consequence of the loss of ecological memory is the tendency to repeat the miscues of the past, especially the blatant disregard for natural and cultural heritage, as suburbanisation engulfs the area. While the swamps of inner Perth remain only in the names of streets, existing wetlands in the metropolitan area are still being threatened, as the Roe Highway (Roe 8) Campaign demonstrates. To re-imagine Perth’s lost landscape, we used several colonial survey maps to plot the location of the original lakes and swamps. At this time, a series of interconnecting waterbodies, known as the Perth Great Lakes, spread across the north of the city (Bekle and Gentilli). This phase required the earliest cartographic sources (Figure 3) because, by 1855, city maps no longer depicted wetlands. We synthesised contextual information, such as well depths, geological and botanical maps, settlers’ accounts, Nyoongar oral histories, and colonial-era artists’ impressions, to produce renderings of Perth. This diverse collection of primary and secondary materials served as the basis for creating new images of the city. Team member Jeff Murray interpolated Balbuk’s route using historical mappings and accounts, topographical data, court records, and cartographic common sense. He determined that Balbuk would have camped on the high ground of the southern part of Lake Kingsford rather than the more inundated northern part (Figure 2). Furthermore, she would have followed a reasonably direct course north of St Georges Terrace (contrary to David Whish-Wilson’s imaginings) because she was barred from Government House for protesting. This easier route would have also avoided the springs and gullies that appear on early maps of Perth. Figure 3. Townsite of Perth in Western Australia by Colonial Draftsman A. Hillman and John Septimus Roe (1838). This map of Perth depicts the wetlands that existed overlaid by the geomentric grid of the new city. Image Credit: State Library of Western Australia (Image Number: BA1961/14). Additionally, we produced an animated display based on aerial photographs to show the historical extent of change. Prompted by the build up to World War II, the earliest aerial photography of Perth dates from the late 1930s (Dixon 148–54). As “Sandgroper” noted, by this time, most of the urban wetlands had been drained or substantially modified. The animation revealed considerable alterations to the formerly swampy Swan River shoreline. Most prominent was the transformation of the Matagarup shallows across the Swan River, originally consisting of small islands. Now traversed by a causeway, this area was transformed into a single island, Heirisson—the general site of Balbuk’s birth. The animation and accompanying materials (maps, images, and writings) enabled viewers to apprehend the changes in real time and to imagine what the city was once like. Re-imagining Perth’s Urban Heart The physical environment of inner Perth includes virtually no trace of its wetland origins. Consequently, we considered whether a representation of Perth, as it existed previously, could enhance public understanding of natural heritage and thereby increase its value. For this reason, interpretive materials were exhibited centrally at Perth Town Hall. Built partly by convicts between 1867 and 1870, the venue is close to the site of the 1829 Foundation of Perth, depicted in George Pitt Morrison’s painting. Balbuk’s grandfather “camped somewhere in the city of Perth, not far from the Town Hall” (Bates, “Fanny”). The building lies one block from the site of the railway station on the site of Lake Kingsford, the subsistence grounds of Balbuk and her forebears: The old swamp which is now the Perth railway yards had been a favourite jilgi ground; a spring near the Town Hall had been a camping place of Maiago […] and others of her fathers' folk; and all around and about city and suburbs she had gathered roots and fished for crayfish in the days gone by. (Bates, “Derelicts” 55) Beginning in 1848, the draining of Lake Kingsford reached completion during the construction of the Town Hall. While the swamps of the city were not appreciated by many residents, some organisations, such as the Perth Town Trust, vigorously opposed the reclamation of the lake, alluding to its hydrological role: That, the soil being sand, it is not to be supposed that Lake Kingsford has in itself any material effect on the wells of Perth; but that, from this same reason of the sandy soil, it would be impossible to keep the lake dry without, by so doing, withdrawing the water from at least the adjacent parts of the townsite to the same depth. (Independent Journal of Politics and News 3) At the time of our exhibition, the Lake Kingsford site was again being reworked to sink the railway line and build Yagan Square, a public space named after a colonial-era Nyoongar leader. The project required specialised construction techniques due to the high water table—the remnants of the lake. People travelling to the exhibition by train in October 2014 could have seen the lake reasserting itself in partly-filled depressions, flush with winter rain (Figure 4).Figure 4. Rise of the Repressed (2014). Water Rising in the former site of Lake Kingsford/Irwin during construction, corner of Roe and Fitzgerald Streets, Northbridge, WA. Image Credit: Nandi Chinna (2014). The exhibition was situated in the Town Hall’s enclosed undercroft designed for markets and more recently for shops. While some visited after peering curiously through the glass walls of the undercroft, others hailed from local and state government organisations. Guest comments applauded the alternative view of Perth we presented. The content invited the public to re-imagine Perth as a city of wetlands that were both environmentally and culturally important. A display panel described how the city’s infrastructure presented a hindrance for Balbuk as she attempted to negotiate the once-familiar route between Yoonderup and Lake Kingsford (Figure 2). Perth’s growth “restricted Balbuk’s wanderings; towns, trains, and farms came through her ‘line of march’; old landmarks were thus swept away, and year after year saw her less confident of the locality of one-time familiar spots” (Bates, “Fanny”). Conserving Wetlands: From Re-Claiming to Re-Valuing? Imagination, for philosopher Roger Scruton, involves “thinking of, and attending to, a present object (by thinking of it, or perceiving it, in terms of something absent)” (155). According to Scruton, the feelings aroused through imagination can prompt creative, transformative experiences. While environmental conservation tends to rely on data-driven empirical approaches, it appeals to imagination less commonly. We have found, however, that attending to the present object (the city) in terms of something absent (its wetlands) through evocative visual material can complement traditional conservation agendas focused on habitats and species. The actual extent of wetlands loss in the Swan Coastal Plain—the flat and sandy region extending from Jurien Bay south to Cape Naturaliste, including Perth—is contested. However, estimates suggest that 80 per cent of wetlands have been lost, with remaining habitats threatened by climate change, suburban development, agriculture, and industry (Department of Environment and Conservation). As with the swamps and lakes of the inner city, many regional wetlands were cleared, drained, or filled before they could be properly documented. Additionally, the seasonal fluctuations of swampy places have never been easily translatable to two-dimensional records. As Giblett notes, the creation of cartographic representations and the assignment of English names were attempts to fix the dynamic boundaries of wetlands, at least in the minds of settlers and administrators (Postmodern 72–73). Moreover, European colonists found the Western Australian landscape, including its wetlands, generally discomfiting. In a letter from 1833, metaphors failed George Fletcher Moore, the effusive colonial commentator, “I cannot compare these swamps to any marshes with which you are familiar” (220). The intermediate nature of wetlands—as neither land nor lake—is perhaps one reason for their cultural marginalisation (Giblett, Postmodern 39). The conviction that unsanitary, miasmic wetlands should be converted to more useful purposes largely prevailed (Giblett, Black 105–22). Felicity Morel-EdnieBrown’s research into land ownership records in colonial Perth demonstrated that town lots on swampland were often preferred. By layering records using geographic information systems (GIS), she revealed modifications to town plans to accommodate swampland frontages. The decline of wetlands in the region appears to have been driven initially by their exploitation for water and later for fertile soil. Northern market gardens supplied the needs of the early city. It is likely that the depletion of Nyoongar bush foods predated the flourishing of these gardens (Carter and Nutter). Engaging with the history of Perth’s swamps raises questions about the appreciation of wetlands today. In an era where numerous conservation strategies and alternatives have been developed (for example, Bobbink et al. 93–220), the exploitation of wetlands in service to population growth persists. On Perth’s north side, wetlands have long been subdued by controlling their water levels and landscaping their boundaries, as the suburban examples of Lake Monger and Hyde Park (formerly Third Swamp Reserve) reveal. Largely unmodified wetlands, such as Forrestdale Lake, exist south of Perth, but they too are in danger (Giblett, Black Swan). The Beeliar Wetlands near the suburb of Bibra Lake comprise an interconnected series of lakes and swamps that are vulnerable to a highway extension project first proposed in the 1950s. Just as the Perth Town Trust debated Lake Kingsford’s draining, local councils and the public are fiercely contesting the construction of the Roe Highway, which will bisect Beeliar Wetlands, destroying Roe Swamp (Chinna). The conservation value of wetlands still struggles to compete with traffic planning underpinned by a modernist ideology that associates cars and freeways with progress (Gregory). Outside of archives, the debate about Lake Kingsford is almost entirely forgotten and its physical presence has been erased. Despite the magnitude of loss, re-imagining the city’s swamplands, in the way that we have, calls attention to past indiscretions while invigorating future possibilities. We hope that the re-imagining of Perth’s wetlands stimulates public respect for ancestral tracks and songlines like Balbuk’s. Despite the accretions of settler history and colonial discourse, songlines endure as a fundamental cultural heritage. Nyoongar elder Noel Nannup states, “as people, if we can get out there on our songlines, even though there may be farms or roads overlaying them, fences, whatever it is that might impede us from travelling directly upon them, if we can get close proximity, we can still keep our culture alive. That is why it is so important for us to have our songlines.” Just as Fanny Balbuk plied her songlines between Yoonderup and Lake Kingsford, the traditional custodians of Beeliar and other wetlands around Perth walk the landscape as an act of resistance and solidarity, keeping the stories of place alive.

Therefore, the problem of rational use of natural resources, in particular protection of early spring plant species is very important. However, literary sources analysis only reveals data on the biology of species of this genus. The present research,conducted in the spring of 2017-2019, focuses on anatomical and morphological features of two Altai species: Gagealutea and Gagea minima; these features were studied, clarified and confirmed by drawings and photographs. The anatomical structure of the stem and leaf blade was studied in detail. The obtained research results will prove useful for studies of medicinal raw materials and honey plants. The aforementioned species are similar in morphological features, yet G. minima issmaller in size, and its shoots appear earlier than those of other species Keywords: Flora,gageas,Altai species,vegetative organs., Refference: I.

Voropaeva,Viktoriay A. Kolomytseva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00042 Abstract: This study was aimed at examining the influence of succession cropping on the economic efficiency of no-till field crop rotations on the black earth in the zone of unstable moistening of the Stavropol krai. A long-term stationary experiment was conducted to examine for the purpose nine field crop rotation patterns different in the number of fields (four to six), set of crops, and their succession in crop rotation. The respective shares of legumes, oilseeds, and cereals in the cropping pattern were 17 to 33, 17 to 40, and 50 to 67 %. It has been established that in case of no-till field crop cultivation the economic efficiency of plant production depends on the set of crops and their succession in rotation. The most economically efficient type of crop rotation is the soya-winter wheat-peas-winter wheat-sunflower-corn six-field rotation with two fields of legumes: in this rotation 1 ha of crop rotation area yields 3 850 grain units per ha at a grain unit prime cost of 5.46 roubles; the plant production output return and profitability were 20,888 roubles per ha and 113 %, respectively. The high production profitabilities provided by the soya-winter wheat-sunflower four-field and the soya-winter-wheat-sunflower-corn-winter wheat five-field crop rotation are 108.7 and 106.2 %, respectively. The inclusion of winter wheat in crop rotation for two years in a row reduces the second winter wheat crop yield by 80 to 100 %, which means a certain reduction in the grain unit harvesting rate to 3.48-3.57 thousands per ha of rotation area and cuts the production profitability down to 84.4-92.3 %. This is why, no-till cropping should not include winter wheat for a second time Keywords: No-till technology,crop rotation,predecessor,yield,return,profitability, Refference: I Badakhova G.

View | Download DEVELOPMENT AND TESTING OF AUTONOMOUS PORTABLE SEISMOMETER DESIGNED FOR USE AT ULTRALOW TEMPERATURES IN ARCTIC ENVIRONMENT Authors: Mikhail A. Abaturov,Yuriy V. Sirotinskiy, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00043 Abstract: This paper is concerned with solving one of the issues of the general problem of designing geophysical equipment for the natural climatic environment of the Arctic. The relevance of the topic has to do with an increased global interest in this region. The paper is aimed at considering the basic principles of developing and the procedure of testing seismic instruments for use at ultralow climatic temperatures. In this paper the indicated issue is considered through the example of a seismic module designed for petroleum and gas exploration by passive seismoacoustic methods. The seismic module is a direct-burial portable unit of around 5 kg in weight, designed to continuously measure and record microseismic triaxial orthogonal (ZNE) noise in a range from 0.1 to 45 Hz during several days in autonomous mode. The functional chart of designing the seismic module was considered, and concrete conclusions were made for choosing the necessary components to meet the ultralow-temperature operational requirements. The conclusions made served for developing appropriate seismic module. In this case, the components and tools used included a SAFT MP 176065 xc low-temperature lithium cell, industrial-spec electronic component parts, a Zhaofeng Geophysical ZF-4.5 Chinese primary electrodynamic seismic sensor, housing seal parts made of frost-resistant silicone materials, and finely dispersed silica gel used as water-retaining sorbent to avoid condensation in the housing. The paper also describes a procedure of low-temperature collation tests at the lab using a New Brunswick Scientific freezing plant. The test results proved the operability of the developed equipment at ultralow temperatures down to -55°C. In addition, tests were conducted at low microseismic noises in the actual Arctic environment. The possibility to detect signals in a range from 1 to 10 Hz at the level close to the NLNM limit (the Peterson model) has been confirmed, which allows monitoring and exploring petroleum and gas deposits by passive methods. As revealed by this study, the suggested approaches are efficient in developing high-precision mobile seismic instruments for use at ultralow climatic temperatures. The solution of the considered instrumentation and methodical issues is of great practical significance as a constituent of the generic problem of Arctic exploration.

View | Download COMPARATIVE ANALYSIS OF RESULTS OF TREATMENT OF PATIENTS WITH FOOT PATHOLOGY WHO UNDERWENT WEIL OPEN OSTEOTOMY BY CLASSICAL METHOD AND WITHOUT STEOSYNTHESIS Authors: Yuriy V. Lartsev,Dmitrii A. Rasputin,Sergey D. Zuev-Ratnikov,Pavel V.Ryzhov,Dmitry S. Kudashev,Anton A. Bogdanov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00044 Abstract: The article considers the problem of surgical correction of the second metatarsal bone length. The article analyzes the results of treatment of patients with excess length of the second metatarsal bones that underwent osteotomy with and without osteosynthesis. The results of treatment of patients who underwent metatarsal shortening due to classical Weil-osteotomy with and without osteosynthesis were analyzed. The first group consisted of 34 patients. They underwent classical Weil osteotomy. The second group included 44 patients in whomosteotomy of the second metatarsal bone were not by the screw. When studying the results of the treatment in the immediate postoperative period, weeks 6, 12, slightly better results were observed in patients of the first group, while one year after surgical treatment the results in both groups were comparable. One year after surgical treatment, there were 2.9% (1 patient) of unsatisfactory results in the first group and 4.5% (2 patients) in the second group. Considering the comparability of the results of treatment in remote postoperative period, the choice of concrete method remains with the operating surgeon.

Shulunova,Alexander I.Sidelnikov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00045 Abstract: Purpose.To determine the quantitative echogenicity indicators (and their ratio) of the layers of stomach and small intestine wall in healthy dogs. Methods. A prospective 3-year study of 86 healthy dogs (aged 1-7 yrs) of different breeds and of both sexes. Echo homogeneity and echogenicity of the stomach and intestines wall were determined by the method of Silina, T.L., et al. (2010) in absolute values ​​of average brightness levels of ultrasound image pixels using the 8-bit scale with 256 shades of gray. Results. Quantitative echogenicity indicators of the stomach and the small intestine wall in dogs were determined. Based on the numerical values ​​characterizing echogenicity distribution in each layer of a separate structure of the digestive system, the coefficient of gastric echogenicity is determined as 1:2.4:1.1 (mucosa/submucosa/muscle layers, respectively), the coefficient of duodenum and jejunum echogenicity is determined as 1:3.5:2 and that of ileum is 1:1.8:1. Clinical significance. The echogenicity coefficient of the wall of the digestive system allows an objective assessment of the stomach and intestines wall and can serve as the basis for a quantitative assessment of echogenicity changes for various pathologies of the digestive system Keywords: Ultrasound (US),echogenicity,echogenicity coefficient,digestive system,dogs,stomach,intestines, Refference: I.

Belyayeva,Fatima S. Datieva,Larisa R. Datieva, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00046 Abstract: The aim of this work was to assess the functional reserves of the body to quantify individual health; adaptation, psychophysiological characteristics of the health quality of medical students in different seasons of the year. When studying the temporal organization of physiological functions, the rhythm parameters of physiological functions were determined, followed by processing the results using the Cosinor Analysis program, which reveals rhythms with an unknown period for unequal observations, evaluates 5 parameters of sinusoidal rhythms (mesor, amplitude, acrophase, period, reliability). The essence of desynchronization is the mismatch of circadian rhythms among themselves or destruction of the rhythms architectonics (instability of acrophases or their disappearance). Desynchronization with respect to the rhythmic structure of the body is of a disregulatory nature, most pronounced in pathological desynchronization. High neurotism, increased anxiety reinforces the tendency to internal desynchronization, which increases with stress. During examination stress, students experience a decrease in the stability of the temporary organization of the biosystem and the tension of adaptive mechanisms develops, which affects attention, mental performance and the quality of adaptation to the educational process. Time is shortened and the amplitude of the “initial minute” decreases, personal and situational anxiety develops, and the level of psychophysiological adaptation decreases. The results of the work are priority because they can be used in assessing quality and level of health.

Tsvetkov, DOI: https://doi.org/10.26782/jmcms.spl.10/2020.06.00047 Abstract: The present study of comparison methods based on the triadic model introduces the following concepts: the relation of comparability and the relation of comparison, and object comparison and attributive comparison. The difference between active and passive qualitative comparison is shown, two triadic models of passive and active comparison and models for comparing two and three objects are described. Triadic comparison models are proposed as an alternative to dyadic comparison models. Comparison allows finding the common and the different; this approach is proposed for the analysis of the nomothetic and ideographic method of obtaining knowledge. The nomothetic method identifies and evaluates the general, while the ideographic method searches for unique in parameters and in combinations of parameters. Triadic comparison is used in systems and methods of argumentation, as well as in the analysis of consistency/inconsistency.
