Full textAbstract:
Harpobittacus Gerstaecker is the largest of the six genera of Australian Bittacidae. Adults occur in eastern, south-eastern and south-western Australian eucalypt woodland and coastal heathland during spring and summer and sometimes autumn. The genus contains 11 species, which are diagnosed in the present revision: H. australis (Klug) [= australis rubripes Riek, syn. nov., = corethrarius (Rambur), = intermedius (Selys-Longchamps)] (south-east Australia, including Tasmania); H. albatus Riek, stat. nov. (= limnaeus Smithers, syn. nov.) (coastal eastern Australia); H. christine, sp. nov. (inland south-east Queensland); H. tillyardi Esben-Petersen ( = nigratus Navás) (coastal eastern Australia); H. rubricatus Riek (inland south-east Australia); H. scheibeli Esben-Petersen (= brewerae Smithers, syn. nov.) (inland and coastal eastern Australia); H. septentrionis, sp. nov. (coastal north Queensland); H. nigriceps (Selys-Longchamps) (mainland south-east Australia); H. similis Esben-Petersen, H. quasisimilis, sp. nov., and H. phaeoscius Riek (all south-west Western Australia). Cladistic analysis has produced the following hypothesis of relationships: (((australis (albatus christine)) (tillyardi rubricatus)) ((similis quasisimilis) ((scheibeli septentrionis) (nigriceps phaeoscius))). Immediate sister-species show little or no overlap in their geographic distributions.

Panetta, FD. "Isozyme Variation in Australian and South-African Populations of Emex australis Steinh." Australian Journal of Botany 38, no. 2 (1990): 161. http://dx.doi.org/10.1071/bt9900161.
Full textAbstract:
Isozyme variation was surveyed at 25 loci in 65 Australian (colonial) and 21 South African (native) populations of Emex australis. Only one polymorphism, restricted in distribution to the eastern States, was observed in Australia. Three additional polymorphisms were detected in South African populations, but most (16) South African populations were indistinguishable from the Australian ones. Thus, the relative uniformity of colonial populations of E. australis reflects the low level of isozyme variation in many populations within its native range.

Full textAbstract:
The Australian and Papua New Guinean species of the water beetle genus Gymnochthebius Orchymont, 1943, are revised, based on the study of 4,904 specimens. The genus is redescribed, and redescriptions are provided for G. australis (Blackburn), G. brisbanensis (Blackburn), G. clarki (Deane), G. levis (Deane), G. lividus (Deane), G. notalis (Deane), and G. tenebricosus (Deane). Lectotypes are designated for Ochthebius australis Blackburn, 1888, and Ochthebius tenebricosus Deane, 1931. Ochthebius fischeri Deane, 1931, and Ochthebius leai Deane, 1931, are synonymized with Ochthebius australis Blackburn, 1888; Ochthebius flavocinctus Deane 1933, is synonymized with Ochthebius lividus Deane, 1933; and Ochthebius angustipennis Deane, 1931, is synonymized with Ochthebius clarki Deane, 1931. Twenty-nine new species are described, and a key to the 36 species known from Australia and Papua New Guinea is given. High resolution digital images of all primary types are presented (online version in color), the male genitalia are illustrated, and Australian geographic distributions are mapped. Only one species, G. clarki, inhabits both Australia and Papua New Guinea; two species, G. bacchusi n. sp. and G. papua n. sp. are endemic to Papua New Guinea; 33 species are endemic to Australia. Members of Gymnochthebius are found at the gravelly/sandy/silty margins of flowing and standing water. A preliminary grouping of species according to microhabitat substrate is presented. Correspondences between ventral morphology and microhabitat preferences suggest that a few species are evolving toward humicolous habits. New species of Gymnochthebius are: G. angulonotus (Queensland, Tinaroo Creek Road via Mareeba), G. bacchusi (Papua New Guinea, Morobe District, c. 7 miles Lae Bulolo Road), G. benesculptus (South Australia, Warburton River, 1 km N White Bull Yard Kalamurina Stn.), G. coruscus (South Australia, Warburton River, 1 km N White Bull Yard Kalamurina Stn.), G. fontinalis (South Australia, Elizabeth (Mound) Springs, 7 km NW Coward Springs R.S.), G. fumosus (New South Wales, Sydney), G. hesperius (Western Australia, Lyndon River Bridge), G. inlineatus (Western Australia, Millstream, creek near Deep Reach), G. lustrosulcus (Queensland, Cloncurry), G. minipunctus (Northern Territory, Palm Valley), G. nanosetus (Northern Territory, Roderick Creek, Gregory National Park), G. nicki (Victoria, Possum Hollow falls, West branch Tarwin River, 5.6 km SSW Allambee), G. nigriceps (South Australia, Mound Spring near Coward Springs), G. papua (Papua New Guinea, Morobe District, ca. 10 km S Garaina Saureri), G. perpunctus (South Australia, Somme Creek, between Angaston and Sedan), G. pluvipennis (South Australia, Warburton

Full textAbstract:
Abstract During austral winter and spring, the El Niño–Southern Oscillation (ENSO) and the Indian Ocean dipole (IOD), individually or in combination, induce equivalent-barotropic Rossby wave trains, affecting midlatitude Australian rainfall. In autumn, ENSO is at its annual minimum, and the IOD has usually not developed. However, there is still a strong equivalent-barotropic Rossby wave train associated with tropical Indian Ocean sea surface temperature (SST) variability, with a pressure anomaly to the south of Australia. This wave train is similar in position, but opposite in sign, to the IOD-induced wave train in winter and spring and has little effect on Australian rainfall. This study shows that the SST in the southeastern tropical Indian Ocean (SETIO) displays a high variance during austral autumn, with a strong influence on southeast and eastern Australian rainfall. However, this influence is slightly weaker than that associated with SST to the north of Australia, which shares fluctuations with SST in the SETIO region. The SST north of Australia is coherent with a convective dipole in the tropical Pacific Ocean, which is the source of a wave train to the east of Australia influencing rainfall in eastern Australia. ENSO Modoki is a contributor to the convective dipole and as a result it exerts a weak influence on eastern Australian rainfall through the connecting north Australian SST relationship. Thus, SST to the north of Australia acts as the main agent for delivering the impact of tropical Indo-Pacific variability to eastern Australia.

Full textAbstract:
This is a summary of the southern hemisphere atmospheric circulation patterns and meteorological indices for austral winter 2017; an account of seasonal rainfall and temperature for the Australian region is also provided. The El Niño–Southern Oscillation was neutral during winter 2017, as was the Indian Ocean Dipole. A positive Southern Annular Mode influenced the climates of southern hemisphere countries at times during winter. Despite the lack of large-scale ocean influences, mean temperatures for the season were very much above average across large areas of Australia, New Zealand, southern Africa and South America. Precipitation during the season was below average across much of Australia, South Africa and western areas of Chile and Argentina, but above average in some southern and eastern areas of South America.

Full textAbstract:
Abstract. This study uses two climate models and six scenarios of prescribed methane emissions to compare modelled and observed atmospheric methane between 1994 and 2007, for Cape Grim, Australia (40.7° S, 144.7° E). The model simulations follow the TransCom-CH4 protocol and use the Australian Community Climate and Earth System Simulator (ACCESS) and the CSIRO Conformal-Cubic Atmospheric Model (CCAM). Radon is also simulated and used to reduce the impact of transport differences between the models and observations. Comparisons are made for air samples that have traversed the Australian continent. All six emission scenarios give modelled concentrations that are broadly consistent with those observed. There are three notable mismatches, however. Firstly, scenarios that incorporate interannually varying biomass burning emissions produce anomalously high methane concentrations at Cape Grim at times of large fire events in southeastern Australia, most likely due to the fire methane emissions being unrealistically input into the lowest model level. Secondly, scenarios with wetland methane emissions in the austral winter overestimate methane concentrations at Cape Grim during wintertime while scenarios without winter wetland emissions perform better. Finally, all scenarios fail to represent a methane source in austral spring implied by the observations. It is possible that the timing of wetland emissions in the scenarios is incorrect with recent satellite measurements suggesting an austral spring (September-October-November), rather than winter, maximum for wetland emissions.

Full textAbstract:
All Australian records of the Eurasian Hobby Falco subbuteo are summarised. Before 2016, the only Australian records of the Eurasian Hobby were on external territories to the north-west of the mainland. Each year between 2016 and 2021 a single Eurasian Hobby was observed as an austral summer visitor to the Swan Coastal Plain in south-western Western Australia. These sightings involved an adult in 2016, 2019 and 2020, and single immature birds in 2017–2018. The age of the Hobby seen in 2020–2021 was undetermined. As it appears that multiple individuals have been recorded across years, it is likely that the species is now more than just an accidental vagrant to Australia.

Abstract. Australian dust emissions are highly episodic, and this may increase the importance of Australian dust as a climate feedback agent. We compare two 160-year coupled atmosphere-ocean simulations of modern-day climate using the CSIRO Mark 3.6 global climate model (GCM). The first run (DUST) includes an interactive treatment of mineral dust and its direct radiative effects. The second run (NODUST) is otherwise identical, but has the Australian dust source set to zero. We focus on the austral spring season, when the correlation between rainfall and the El Niño Southern Oscillation (ENSO) is strongest over Australia. The ENSO-rainfall relationship over eastern Australia is stronger in the DUST run: dry (El Niño) years tend to be drier, and wet (La Niña) years wetter. The amplification of ENSO-related rainfall variability over eastern Australia represents an improvement relative to observations. The effect is driven by ENSO-related anomalies in radiative forcing by Australian dust over the south-west Pacific Ocean; these anomalies increase (decrease) surface evaporation in La Niña (El Niño) years. Some of this moisture is advected towards eastern Australia, where increased (decreased) moisture convergence in La Niña (El Niño) years increases the amplitude of ENSO-related rainfall variability. The modulation of surface evaporation by dust over the south-west Pacific occurs via surface radiative forcing and dust-induced stabilisation of the boundary layer. The results suggest that (1) a realistic treatment of Australian dust may be necessary for accurate simulation of the ENSO-rainfall relationship over Australia, and (2) radiative feedbacks involving dust may be important for understanding natural rainfall variability over Australia.

Journal of Climate 25, no. 16 (August 15, 2012): 5587–99. http://dx.doi.org/10.1175/jcli-d-11-00324.1.
Full textAbstract:
Abstract Off the Western Australia coast, interannual variations of wind regime during the austral winter and spring are significantly correlated with the Indian Ocean dipole (IOD) and the southern annular mode (SAM) variability. Atmospheric general circulation model experiments forced by an idealized IOD sea surface temperature anomaly field suggest that the IOD-generated deep atmospheric convection anomalies trigger a Rossby wave train in the upper troposphere that propagates into the southern extratropics and induces positive geopotential height anomalies over southern Australia, independent of the SAM. The positive geopotential height anomalies extended from the upper troposphere to the surface, south of the Australian continent, resulting in easterly wind anomalies off the Western Australia coast and a reduction of the high-frequency synoptic storm events that deliver the majority of southwest Australia rainfall during austral winter and spring. In the marine environment, the wind anomalies and reduction of storm events may hamper the western rock lobster recruitment process.

Full textAbstract:
The carabid beetle tribe Moriomorphini attains a disjunct austral geographical distribution, with member taxa occupying Australia, New Zealand, New Caledonia, the Sundas, southern South America and Polynesia. The group arose in Australia, the area exhibiting the greatest generic diversity for the tribe. In this contribution, two new genera are added to the Australian fauna. Pharetis thayerae, gen. nov., sp. nov., is described from Grenvillia, New South Wales, and Spherita newtoni, gen. nov., sp. nov., is described from Avon Valley National Park, Western Australia. Their phylogenetic placement within the tribe is accomplished by parsimony analysis based on 208 morphological characters across 124 taxa, 114 in-group species and 10 outgroup taxa representing Trechini, Psydrini and Patrobini. Nearly all polytypic moriomorphine genera are represented in the analysis by at least two exemplars, allowing initial tests of generic monophyly. A revised classification is proposed for Moriomorphini, with subtribal clades related as (Amblytelina + (Moriomorphina + Tropopterina)). The Western Australian genus Spherita is placed as adelphotaxon to Sitaphe Moore, a genus restricted to tropical montane Queensland. From the phylogenetic analysis, other non-contemporaneous east–west Australian disjunctions can be inferred, as well as multiple trans-Tasman area relationships between eastern Australia and New Zealand, all proposed to be of Miocene age. Pharetis exhibits a disjunct, trans-Antarctic relationship with Tropopterus Solier, its sister-group, distributed in southern South America. Alternative vicariance-based and dispersal-based hypotheses are discussed for the origin of Tropopterus. A review of the taxonomic development of the tribe illustrates the signal importance of monotypic genera in elucidating biological diversity.

Full textAbstract:
A new species of Mandarin dogfish, Cirrhigaleus australis n. sp., is described based on specimens from southeastern Australia. Australian populations were previously considered to be conspecific with Cirrhigaleus barbifer from the western North Pacific and Indonesia, but recent investigations revealed that the two forms differ in morphology and in the structure of the CO1 gene. Cirrhigaleus australis has a smaller eye, shorter dorsal-caudal space, and smaller pectoral fins and dorsal fins and spines. These species are clearly separable from the only other congener, C. asper, and all other members of the family Squalidae, by the possession of a greatly produced barbel on their anterior nasal flap. The new species occurs in temperate waters of eastern Australia, and possibly New Zealand.

Full textAbstract:
The biscuit star Tosia australis Gray, 1840 is a well known component of the shallow rocky reef fauna of south-eastern Australia. The putative T. australis species complex was subjected to reproductive, morphometric and molecular analyses. Molecular analyses of the data from three markers (mitochondrial COI and 16S rRNA and the nuclear non-coding region ITS2) confirmed the presence of a cryptic species, the morphology of which does not agree with any of the existing nominal species. Two separate reproductive modes were observed within the complex and documented via scanning electron microscopy. T. neossia, sp. nov., described herein from south-eastern Australia, is shown to release gametes from gonopores on the actinal surface. Embryos develop first into non-feeding, non-swimming brachiolaria, and then into tripod brachiolaria before metamorphosis. No surface cilia are present at any point throughout development of T. neossia. T. australis sensu stricto is shown to release gametes from the abactinal surface. Embryos develop into non-feeding, swimming brachiolaria before metamorphosis. Whereas T. australis var. astrologorum is confirmed as synonymous with T. australis, the status of the putative Western Australian taxon T. nobilis remains unresolved.

Full textAbstract:
The Australian members of the vetigastropod family Anatomidae are revised and two new species are described. The family has thus far been treated as a subfamily of Scissurellidae, but recent molecular evidence (Geiger & Thacker, unpubl. data) indicates that Scissurellinae plus Anatominaeis not monophyletic, and full family rank is warranted for a group containing the genera Anatoma and Thieleella. Seven species from Australia belonging in Anatomidae are discussed and illustrated by SEM: Anatoma aupouria (Powell, 1937) mainly from New Zealand, though with some Australian records; A. australis (Hedley, 1903), A. funiculata n. sp., An turbinata (A. Adams, 1862), which has been misidentified in the past as the South African A. agulhasensis (Thiele, 1925), A. tobeyoides n. sp., Thieleella equatoria (Hedley, 1899) with a second known specimen, and T. gunteri (Cotton & Godfrey, 1933). Other species that have been (erroneously) indicated from Australia are discussed. A neotype is designated for A. agulhasensis from South Africa for taxon stabilization.

In July 1998 the Soutb Australian goverment released a Discussion Paper concern ing the future of occupational bealth and safety regulation in South Australia. In examining the paradigm shift proposed in the Discussion Paper, this paper highlights the importance of workplace health and safety as public polig issues in Australia and seeks to locate the Discussion Paper within the broader context of deregulatory changes in the administration of occupational health and safety legislation that have occurred in South Australia in recent years. It identifies several fundamental flaws in the proposals put forward for change and suggests that the major problem with tbe regulation of occupational health and safety in South Australia is the failure to effectively administer the legislation. The paper also advances a number of proposals designed to achieve greater compliance with the legislation. It concludes that the major proposals contained in the Discussion Paper are unlikely to find widespread practical expression.

Phylogenetic and morphological analyses, male morphology, and hybrid crossing indicate that a population from Wardang Island, South Australia, is distinct from the monophyletic series of populations of Aedes (Halaedes) australis (Erichson) 1842 from Victoria, Tasmania, New South Wales, and New Zealand. The name Aedes (Halaedes) wardangensis has been assigned to the new species. Phylogenetic analysis of DNA sequences from the cytochrome oxidase II and internal transcribed spacer loci support the resurrection of Aedes (Halaedes) ashworthi Edwards, 1921 (Brust and Mahon, 1997). Aedes ashworthi is known only from Western Australia and was found to be infertile when crossed with Ae. wardangensis from South Australia and Ae. australis from New Zealand. The hybrid of Ae. australis from New South Wales × Ae. australis from New Zealand was fertile for three generations, documenting these as conspecific.

The genus Lithophyllum (Lithophylloideae, Corallinaceae, Rhodophyta) is represented by six species in south-eastern Australia L. chamberlainianum Woelkerling & Campbell, L. corallinae (Crouan & Crouan) Heydrich, L. cuneatum Keats, L. pustulatum (Lamouroux) Foslie, L. riosmenae, sp. nov., and L. stictaeforme (Areschoug in Agardh) Hauck. Four of these taxa are commonly found in Australia, whereas L. cuneatum was previously known only from Fiji and L. riosmenae is newly described. Morphological and anatomical accounts are provided, including keys, information on distribution, nomenclature and habitat in south-eastern Australia. South-eastern Australian species are primarily delimited on characters relating to tetrasporangial conceptacles and the presence/absence of a semi-endophytic habit. Ten species of Lithophyllum are now confirmed to occur in Australia and their diagnostic characters are detailed. Confirmed Australian species of Lithophyllum are primarily delimited on characters relating to tetrasporangial conceptacles, the presence/absence of a semi-endophytic habit and the growth-form. Biogeographic comparisons between south-eastern Australia and other Australian biogeographic regions are also made. Eight species of Lithophyllum are known to occur in southern Australia, three in tropical eastern Australia and three in subtropical western Australia. Southern and south-eastern Australia show major overlap, with five species occurring in both regions. L. pustulatum and L. stictaeformae are widely distributed, having been confirmed to occur in eastern tropical, western subtropical, warm temperate and cold temperate waters within Australia.

Full textAbstract:
In Australian waters, southern right whales Eubalaena australis form 2 genetically distinct populations that have shown contrasting patterns of recovery since whaling ceased: a western population in South Australia and Western Australia and an eastern population in southeastern Australia (Tasmania, Victoria and New South Wales). Here, we provide an abundance estimate derived from a breeding female superpopulation mark-recapture model for the southeastern southern right whale population. The population comprises 268 individuals (68 breeding females) and has increased at a rate of 4.7% per annum between 1996 and 2017. There has been no significant change in the annual abundance of mother-calf pairs sighted at the only calving ground (Logans Beach in Victoria) over the last 3 decades. The total number of southern right whales (i.e. all adults and calves) using the southeastern Australian coastline has increased by 7% since 1985. Unlike the population estimate (which was restricted to breeding females sighted prior to the post-breeding southward migration), this estimate is likely to include transiting whales from the southwestern population. The theoretical population model predicts 19 breeding females at Logans Beach in 2018 and 28 in 2028; the actual number of breeding females, as of 2018, is 14. This study provides the first complete estimate of population size and rate of increase of southern right whales along the southeastern Australian coastline. This knowledge is critical for assessing population status and recovery of southern right whales in Australia. It provides a basis for monitoring persistence and responses of the population to environmental stressors.

Full textAbstract:
Abstract Rainfall over northern Australia (NA) in austral summer is the largest water source of Australia. Previous studies have suggested a strong zonal-dipole trend pattern in austral summer rainfall since 1950, with rainfall increasing in northwest Australia (NWA) but decreasing in northeast Australia (NEA). The dynamics of rainfall increase in NWA was linked to sea surface temperature (SST) in the south Indian Ocean and the rainfall decrease in NEA was associated with SST in the northeast Indian Ocean. This study reports that, in contrast to a zonal-dipole trend pattern, a dominant wetting pattern over NA has recently been observed in the post-1979 satellite era. The recent NA rainfall increase also manifests as the first leading mode of summer rainfall variability over the Australian continent. Further investigation reveals that SST in the tropical western Pacific (TWP) has replaced the SST in the south and northeast Indian Ocean as the controlling factor responsible for the recent NA rainfall increase. Direct thermal forcing by increasing TWP SST gives rise to an anomalous Gill-type cyclone centered around NA, leading to anomalously high rainfall. As such, the increasing SST in the TWP induces over 50% of the observed rainfall wetting trend over NA. The increased rainfall in turn induces land surface cooling in NA. This mechanism can be confirmed with results obtained from sensitivity experiments of a numerical spectral atmospheric general circulation model. Thus, increasing SST in the TWP has contributed much of the recent summer rainfall increase and consequently the surface cooling over NA.

Water striders or pond skaters belonging to the subfamily Gerrinae are common inhabitants of various types of fresh water throughout eastern and northern Australia. The present paper deals with the 13 species (in 5 genera) known from Australia. Redescriptions or descriptive notes, illustrations, and keys to adults and nymphs of all species are provided and their distributions recorded and mapped.Tenagogerris pallidusand T. femoratus (both from Northern Territory and Western Australia), Tenagogonus australiensis (Queensland), Limnometra ciliodes (Queensland, Papua New Guinea and Irian Jaya), and Limnogonus fossarum gilguy (Northern Territory, Queensland, South Australia, Western Australia, Indo-Malayan Archipelago, and West Pacific to Samoa and Tonga) are described as new. Limnometra poliakanthinaNieser & Chen is synonymised with L. cursitans (Fabricius) and Hydrometra australis Skuse (= Limnometra skusei Torre-Bueno) with Limnogonus luctuosus (Montrouzier). The evolution and zoogeography of Australian water striders are discussed. Finally, we discuss the ecology of the gerrine water striders of Australia in relation to our present knowledge about habitats, phenology, wing polymorphism, and association between species.

Full textAbstract:
Three new species of ghost moth, Oxycanus ephemerous sp. nov., O. flavoplumosus sp. nov., and O. petalous sp. nov. are described from South Australia, New South Wales, and south-west Western Australia, respectively. We illustrate these species and compare morphological and molecular (mtDNA COI gene) characters with similar Oxycanus Walker, 1856 species from Australia. Comparative images of Oxycanus subvaria (Walker, 1856), O. byrsa (Pfitzner, 1933), and O. determinata (Walker, 1856) are figured. The type material of the three new species are held in the Australian National Insect Collection, Canberra, the Western Australian Museum, Perth, and in the South Australian Museum, Adelaide. The type specimens of Oxycanus hildae Tindale, 1964 syn. n. were also examined and the taxon is here considered synonymous with O. subvaria. Concerns are raised about the conservation status of all three new species due to few or localised distribution records.

Abstract. South Australia is the driest state in the driest inhabited country in the world, Australia. Consequently, water is one of South Australia's highest priorities. Focus on water research and sources of water in the state became more critical during the Millenium drought that occurred between 1997 and 2011. In response to increased concern about water sources the South Australian government established The Goyder Institute for Water Research – a partnership between the South Australian State Government, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Flinders University, University of Adelaide and University of South Australia. The Goyder Institute undertakes cutting-edge science to inform the development of innovative integrated water management strategies to ensure South Australia's ongoing water security and enhance the South Australian Government's capacity to develop and deliver science-based policy solutions in water management. This paper focuses on the integrated water resource assessment of the northern Adelaide region, including the key research investments in water and climate, and how this information is being utilised by decision makers in the region.

The banded hare-wallaby (Lagostrophus fasciatus) is an endangered macropodid currently restricted to Bernier and Dorre Islands in Shark Bay, Western Australia. Historically, L. fasciatus was also recorded on the Australian mainland from far western Australia, where it became locally extinct early in the twentieth century. Here we discuss an overlooked museum specimen of L. fasciatus collected in the mid-nineteenth century near Adelaide, South Australia. This specimen considerably extends the known historical distribution of L. fasciatus, validates anecdotal reports of the species from South Australia made by early Australian naturalists, and forms the basis for our description of a new subspecies.

Full textAbstract:
The redlegged earth mite, Halotydeus destructor (Tucker) (Acari: Penthaleidae), is an important pest of pastures, broad-acre crops, and vegetables across southern Australia. Populations of H. destructor in Western Australia have been known to be resistant to pyrethroid and organophosphorus pesticides since 2006 and 2014, respectively. Resistant populations are currently widespread across Western Australia’s southern growing region but have, until now, remained undetected in the large south-eastern Australian range of H. destructor, despite ongoing resistance screening since 2006. Following reports of a field control failure in the Upper South East district in South Australia in 2016, resistance testing determined this South Australian population was resistant to pyrethroid and organophosphorus pesticides. The levels of resistance discovered were similar to resistant H. destructor populations in Western Australia, which are associated with chemical control failures. This work confirms for the first-time that pesticide resistant populations of H. destructor are no longer isolated to Western Australia.

The Australian endemic brine shrimp Parartemia is more speciose than the literature suggests, with eight described species, four new ones added here from South Australia and many undescribed species elsewhere in Australia. P. acidiphila n. sp. occurs in acidic salinas on Eyre Peninsula, in the Gawler Ranges in South Australia and also in the Esperance hinterland, Western Australia, while P. auriciforma n. sp., P. triquetra n. sp. and P. yarleensis n. sp. occur in remote episodic salinas in western South Australia. Introduced Artemia franciscana and A. parthenogenetica are limited to present and defunct salt works; reports of Artemia beyond salt works in South Australia are enigmatic.

Full textAbstract:
Three biogeographic components with very different histories are represented among the tenebrionids of the Australian arid zone: the Indo-Malayan element, which is related mainly to the Indonesian fauna; the Austral Gondwanan element, mainly related to that of southern South America; and one here called Tethyan, related to the fauna of northern hemisphere arid regions. Indo-Malayan groups appear to have arrived comparatively recently, probably by invasion from the north, and are differentiated within the arid zone mainly to the species level. Austral groups are the most diverse and have radiated extensively to generic level from ancestors inhabiting sclerophyll forest, probably by vicariance, within the present arid zone. Tethyan groups are endemic in the arid zone at tribal level and have no forest-inhabiting relatives anywhere. They have often become myrmecophilous in Australia, and because of their distribution patterns in the northern hemisphere, partial occurrence in coastal dunes, and apparently basal phylogenetic positions are surmised to have descended by vicariance from inhabitants of the coastal sand dunes of the Tethys Sea, probably in the Jurassic before there was an arid zone in Australia.

Full textAbstract:
Within New Zealand and eastern Australia, over 58,000 southern right whales were harvested by commercial whalers between 1790 and 1980, with approximately 19,000 harvested from south-eastern Australia. Local extirpation is believed to have led to a loss of cultural memory of calving areas, contributing to the limited recovery of the south-eastern Australian population. While the number of whales observed using the south-eastern Australian coastline is increasing, there has been no change over three decades in the annual abundance of cow-calf pairs at Logans Beach in Warrnambool, Victoria, the only established calving ground in the region. Knowledge of life history parameters of the south-eastern Australian population is lacking. Here, we examine sightings and photo-identification data from southern Australia to investigate calving intervals, long range movements and fidelity to the Logans Beach nursery ground. Sightings data revealed at least 93 calves were born at Logans Beach between 1980 and 2018 (an average of 2.6 per year) with a mean calving interval of 3.5 ± 1.0 years (± SE, n = 34). Comparison between photo-identification catalogues compiled for south-eastern and south-western Australian populations shows that southern right whales are wide ranging within southern Australian waters. Females can be sighted at locations as far apart as 3,800 km across seasons and there is overlap in the wintering range of the south-eastern and south-western populations, with at least 7% of whales using both regions. We also provide the first report of an Australian southern right whale female with strong site fidelity to a calving area in one region relocating long-term to a calving area in another region. This work highlights several knowledge gaps, such as; the location of feeding and conception grounds for this population as well as the degree of mixing between the two Australian populations outside their wintering areas. In addition, the proportion of female calves born at Logans Beach returning to their natal site to calve remains unclear. Our work provides the first assessment of calving rates, movement and site fidelity within the south-eastern Australian population, critical for understanding constraints to recovery and informing conservation management of southern right whales in Australia. Targeted, long-term monitoring programs across the south-eastern Australian region are needed to provide demographic information on which to base predictions of the impacts of anthropogenic threats such as noise disturbance, entanglement and vessel strike.

Australian Journal of Botany 56, no. 7 (2008): 600. http://dx.doi.org/10.1071/bt08043.
Full textAbstract:
Salsola tragus sensu lato (Chenopodiaceae) is found throughout Western Australia and is considered to be a weed in both natural and agricultural ecosystems, although the current taxonomic status of this species is not clear. The taxonomic literature reports morphological variation within Australian populations of the weed, indicating that there may be genetically distinct ecotypes or unidentified subspecies present within the species. A genetic and cytological approach was used to detect variation between 22 populations of S. tragus sensu lato in the south-west of Western Australia. Out-groups used in this study included a population of S. tragus L. from the USA and Maireana brevifolia (R.Br.) Paul G.Wilson (Chenopodiaceae) from Lake Grace. Four genetically distinct groups were identified, which were not closely related to the S. tragus out-group (~60% similarity). Further, these groups and a S. australis R.Br. sample from the USA were all diploid (2n = 18), unlike the tetraploid (2n = 36) S. tragus. The predominant wheatbelt weed, group A, which was previously classified as S. tragus ssp. tragus L., was identified as S. australis. This species is probably native to Australia, given its arrival predated European invasion. Further research is required to clarify the taxonomic status of the other three possible taxa and determine their status in relation to S. australis.

Monthly Weather Review 141, no. 12 (November 25, 2013): 4534–53. http://dx.doi.org/10.1175/mwr-d-13-00040.1.
Full textAbstract:
Abstract The seasonal cycle of blocking in the Australian region is shown to be associated with major seasonal temperature changes over continental Antarctica (approximately 15°–35°C) and Australia (about 8°–17°C) and with minor changes over the surrounding oceans (below 5°C). These changes are superimposed on a favorable background state for blocking in the region resulting from a conjunction of physical influences. These include the geographical configuration and topography of the Australian and Antarctic continents and the positive west to east gradient of sea surface temperature in the Indo-Australian sector of the Southern Ocean. Blocking is represented by a blocking index (BI) developed by the Australian Bureau of Meteorology. The BI has a marked seasonal cycle that reflects seasonal changes in the strength of the westerly winds in the midtroposphere at selected latitudes. Significant correlations between the BI at Australian longitudes and rainfall have been demonstrated in southern and central Australia for the austral autumn, winter, and spring. Patchy positive correlations are evident in the south during summer but significant negative correlations are apparent in the central tropical north. By decomposing the rainfall into its contributions from identifiable synoptic types during the April–October growing season, it is shown that the high correlation between blocking and rainfall in southern Australia is explained by the component of rainfall associated with cutoff lows. These systems form the cyclonic components of blocking dipoles. In contrast, there is no significant correlation between the BI and rainfall from Southern Ocean fronts.

Full textAbstract:
The Australian sea lion is an Australian endemic, restricted to South Australia and Western Australia, with 86% of the population in South Australia. It was listed under the Commonwealth Environment Protection and Biodiversity Conservation Act as Vulnerable in February 2005, and the International Union for the Conservation of Nature has listed it as Endangered. Sea lions are taken as bycatch in the gill-net fishery for school shark and gummy shark, and the risk of extinction of breeding colonies is high even from low levels of bycatch. We assessed trends in pup population size at The Pages Islands, a large breeding colony in South Australia. Pup abundance was estimated by direct counting of live and dead pups; the maximum count in each breeding season was used for trend analysis. The average of direct counts of pups in 14 breeding seasons between 1989–90 and 2009–10 was 473 (s.d. = 58.4). There was no trend in pup numbers, contrasting with two other large colonies: Seal Bay, Kangaroo Island (decreasing), and Dangerous Reef (increasing since 2000). The Australian Sea Lion Management Strategy of the Australian Fisheries Management Authority aims to reduce sea lion bycatch in the shark fishery; a key item is a fishery closure around each breeding colony in South Australia. Implementation of the closure around The Pages should lower the risk of bycatch of its sea lions with foraging areas that previously overlapped with the fishery and should allow the colony’s population size to increase.

Full textAbstract:
The Diatom Index for Australian Rivers (DIAR), originally developed at the genus level, was reformulated at the species level with data from diatom sampling of rivers in the Australian Capital Territory, New South Wales, Queensland, South Australia and Victoria. The resulting Diatom Species Index for Australian Rivers (DSIAR) was significantly correlated with the ARCE (Assessment of River Condition, Environment) index developed in the Australian National Land and Water Resources Audit (NLWRA), and with nine of the ARCE’s constituent indices and sub-indices, across 395 river reaches in south-eastern Australia. These correlations were generally stronger than those shown by the biological index that was used to assess river condition in the NLWRA, the ARCB (Assessment of River Condition, Biota) index based on macroinvertebrates and the Australian River Assessment System (AUSRIVAS). At a finer spatial scale, DSIAR was strongly and significantly correlated with measures of catchment urbanisation for streams in the eastern suburbs of Melbourne, Victoria. DSIAR scores across south-eastern Australia bore little relationship to the latitude, longitude or altitude of sampling sites, suggesting that DSIAR is not greatly affected by macro-geographical position. In addition, DSIAR scores did not vary greatly among small-scale hydraulic environments within a site. DSIAR appears to have potential as a broad-scale indicator of human influences on Australian rivers, especially the effects of agricultural and urban land use, and also for impact studies at a local scale. Further evaluation is warranted to test the sensitivity of the index to natural variables such as catchment geology, and to assess its performance in northern, western and inland Australia.

Australian Journal of Zoology 62, no. 2 (2014): 137. http://dx.doi.org/10.1071/zo13099.
Full textAbstract:
Recent molecular and morphological analyses have shown that chiltoniid amphipods, once thought to be a relictual group, are a diverse and speciose family of Australian freshwater amphipods. As part of a larger examination of the family, chiltoniids from Kangaroo Island in South Australia were collected and analysed using molecular (COI and 28S) and morphological methods in order to understand species distributional patterns and relationships. Kartachiltonia moodyi gen. nov., sp. nov., a spring-associated species endemic to the island, was discovered and populations of three additional mainland species (Austrochiltonia australis, A. dalhousiensis and A. subtenuis) were examined. The island populations of A. australis, A. dalhousiensis and A. subtenuis were found to form natural groups with differing haplotype coalescence times dating from the Early to Mid-Pleistocene. Numerous cycles of regional climate change throughout the Pleistocene are likely to have driven speciation in chiltoniid amphipods in southern Australia and the presence of multiple chiltoniid species at Kangaroo Island indicates that it exists at a likely convergence of species distribution patterns. Three possible hypotheses to explain the evolution and diversity of chiltoniids in southern Australia are discussed as are evidence for potential introduction and long-distance dispersal events.

Known as a monotypic genus for over a century, Marmasoma White, 1916 is an endemic Australian bee fly genus belonging to the tribe Eclimini of the subfamily Bombyliinae. A new species: Marmasoma hortorum sp. nov. is described based on a series of specimens from Western Australia and South Australia. This new species can be easily distinguished from the congener by the inconspicuous pale wing markings and mostly white to pale yellow scales on the body, as well as characters of both male and female genitalia. M. sumptuosum is found in south-eastern Australia, including Tasmania, and some specimens have been collected on Kangaroo Island, South Australia. M. hortorum sp. nov. occurs in south Western Australia, and a pair of specimens has been taken just north of Port Augusta in South Australia. A key to species of Marmasoma is provided.

Identification of Australian species of Nitella is problematic. Several species of monoecious Nitella have been described from south-eastern mainland Australia, but identification of these based on current treatments has been difficult. In response to the discovery of a new monoecious Nitella from the swamps of the Fleurieu Peninsula in South Australia, the monoecious species of Nitella from south-eastern mainland Australia were examined and compared. N. paludigena M.T.Casanova & K.G.Karol is distinguished from other monoecious species on the basis of its overall vegetative morphology and oospore morphology. N. paludigena is found in peaty tea-tree (Leptospermum sp) swamps on the Fleurieu Peninsula in South Australia, and in the south-west of Victoria. A description of the morphology and ecology of the five monoecious Nitella species from south-eastern mainland Australia is given, along with a key.

Amphipods within the family Chiltoniidae are an abundant yet taxonomically poorly known member of Australian freshwater habitats. With only four species known from Australia, the group is inadequately defined and marked by taxonomists as difficult to identify. Recent molecular analyses of chiltoniids from mound springs in South Australia detected several distinct species, prompting a morphological revision of material from the central and southern Lake Eyre region. Clear groups defined by unique combinations of morphological characters (focusing on uropodal, coxal, male gnathopod 2, and antennal morphology) were found that closely correlated with clades found in the molecular analyses. Arabunnachiltonia n. gen. is established for A. murphyi n. sp. from Strangways Springs in South Australia. Wangiannachiltonia n. gen. is established for W. guzikae n. sp. from Davenport Springs in South Australia. The chiltoniid genera are discussed and a key is presented to the known Australian species.

Full textAbstract:
This study focuses on situating children in divorce mediation in South Africa and Australia. This study investigates how South Africa and Australia have domesticated and are implementing relevant international laws and policies that allows hearing the voices of children in divorce mediation. This study found that South Africa and Australia do not have specific legislation that provides hearing in the child's voice in divorce mediation. However, the Australian government funds on-going research to improve the hearing of a child's voice in divorce mediation. Aided by government funding, Australia has developed unique techniques to listen to the child's voice during divorce mediation. The special priority afforded to children’s rights in South Africa and Australia is justified under the Capabilities approach cost-effectiveness principle because it prevents a spiralling need for state intervention later in the lives of its citizens. Some of the techniques used by the Australian government go beyond the requirements of the UNCRC and ACRWC. For example, some FRCs employ technology to screen for child abuse before hearing a child's voice in divorce mediation. Like the Office of the Family Advocate in South Africa, FRCs use a teamwork approach where child consultants and mediators work together to listen to the child's voice during divorce mediation.

Full textAbstract:
Recent data on monocotyledonous geophytes from south-western Australia are compiled and compared with those from other areas of mainly mediterranean climate, especially California, Chile and Victoria, Australia. South-western Australia has a high monocot geophyte diversity of 496 species (7% of an estimated native flora of 7100 vascular species), like Victoria (12%) and the Cape region (14%). As in Victoria, orchids are by far the most important group, with c. 400 species, including those likely to be described once ongoing taxonomic research is completed. South-western Australia has higher geophyte numbers than Victoria in all families considered, but a lower geophyte percentage because of a much higher vascular species total. Among south-western Australian non-orchid geophytes, as in Victoria, the most common storage organ is tuberous roots, followed by corms then bulbs and rhizomes, whereas in California bulbs are by far the most common. The presence of microgeophytes with seed-like storage organs is a special feature seen in several phylogenetically unrelated lineages in the south-western Australian and Victorian geophytic flora, especially on granite outcrops. Divergent phylogenetic history is undoubtedly a major factor underlying striking differences between the monocot geophytes of mediterranean Australia, California, Chile, South Africa and Mediterranean countries. Further studies, particularly on the last two regions, will enable better elucidation of these patterns.

Full textAbstract:
Defining species in the brown algal genus Colpomenia is a challenging endeavour because of their morphological similarity, overlapping phenotypic variation, the absence of conspicuous diagnostic characters, and often lack of reproductive structures crucial for their identification. Thus, the use of molecular tools has become widely used to study Colpomenia taxonomy and evolution. The following four Colpomenia species are described along the Australian coast: C. claytoniae M.Boo, K.M.Lee, G.Y.Cho & W.Nelson, C. ecuticulata M.J.Parsons, C. peregrina Sauvageau, and C. sinuosa (Mertens ex Roth) Derbès & Solier. The objective of this study was to assess the diversity of Colpomenia species in southern and south-eastern Australia by using DNA barcoding techniques and single-marker species delimitation methods. We generated 44 new COI-5P DNA sequences from nine different populations across three Australian states (South Australia, Victoria and Tasmania), and applied 13 variations of four species delimitation methods (ABDG, SPN, PTP, GMYC). Our results recognised three Colpomenia species in the region, namely, C. sinuosa, C. claytoniae, and C. peregrina. Colpomenia sinuosa is the most widely distributed species in Australia. Colpomenia peregrina and C. claytoniae presented high levels of intraspecific genetic divergence. We did not find C. ecuticulata, although it has been previously reported from nearby our sampling area.

These were located at Armidale, Binya, Sutton and Trangie in NSW; Springhurst in Victoria; Jericho in Tasmania; Flaxley in South Australie and Kendenup in Western Australia. A total of 62 lines were evaluated, of which, 29 were Australian native grasses and 33 were introduced. With differences in seed size among species and a lack of information on dormancy and germination characteristics of the native plants, seedlings were transplanted into the field on weed-mat as spaced plants. Lines were compared over a 3-year period from 1998 to 2001. Methods used for determination of forage production, persistence and palatability are described. Information detailing the original collection sites of the germplasm, a list of NLIGN sites where each genotype was evaluated, as well as a detailed description of sites and seasonal conditions is also presented.

"Refugia within refugia: in situ speciation and conservation of threatened Bertmainius (Araneae : Migidae), a new genus of relictual trapdoor spiders endemic to the mesic zone of south-western Australia."

Full textAbstract:
The trapdoor spider family Migidae has a classical Gondwanan distribution and is found on all southern continents except the Indian region. The Australian fauna consists of three genera including Moggridgea O. P. Cambridge from south-western Australia and Kangaroo Island, South Australia; Moggridgea is otherwise widespread throughout Africa. The sole named species of Moggridgea from Western Australia, M. tingle Main, and its unnamed relatives are the subject of the present paper, which was stimulated by concern for the long-term persistence of populations, and the discovery of deep genetic divergences between populations. A phylogeny of the Western Australian species relative to African and South Australian Moggridgea was generated using molecular COI and ITS rDNA data, and based on both molecular and morphological criteria we conclude that the Western Australian taxa should be removed from Moggridgea and transferred to a new genus, Bertmainius. The seven species are delimited using both morphological and molecular criteria: B. tingle (Main) (the type species), and six new species, B. colonus, B. monachus, B. mysticus, B. opimus, B. pandus and B. tumidus. All seven species are considered to be threatened using IUCN criteria, with the major threatening processes being inappropriate fire regimes and climate change.

Full textAbstract:
Olives (Olea europaea ssp. europaea), dispersed from 19th century orchards in the Adelaide area, have become established in remnant bushland as a major environmental weed. Recent expansion of the Australian olive industry has resulted in the widespread planting of olive orchards in South Australia, Victoria, New South Wales, Western Australia, Queensland and parts of Tasmania. This paper reviews the literature on the activity of vertebrate (principally avian) olive predators and their potential as vectors for spreading this plant into Australian remnant bushland. The effects of feralisation on the olive plant, which enhances its capacity for dispersal as a weed, place wider areas of south-eastern Australia at risk. A number of approaches for the control of olives as woody weeds are addressed. Proponents of new agricultural crops have moral and environmental obligations to assess the weed potential of these crops.

Full textAbstract:
Apparently once widespread throughout dense thickets in south-western Australia, the tammar is now much restricted in its distribution. On mainland Australia, isolated populations still persist in Western Australia, but in South Australia, where there is little remaining evidence to confirm that it extended beyond Eyre Peninsula, the wallaby is probably close to extinction. All originally recorded populations on five islands in Western Australia remain, but in South Australia all natural island populations, other than those on Kangaroo I., appear to be extinct. Morphometric analyses of crania representative of most known populations provide a means of assessing their relationships. Canonical variate analysis, the derivation of Mahalanobis distances and subsequent calculation of minimum spanning trees supported the existence of affinities within three major regional groups-a group predominantly from Western Australia, a group from Kangaroo and Greenly Is, South Australia, and a group from New Zealand-all apparently related via a population from Eyre Peninsula, presumably representative of a former widespread mainland population. By cranial criteria, feral tammars established in New Zealand are South Australian in origin although probably not introduced from Kangaroo I.
