Full textAbstract:
Toxoplasma gondii is a cosmopolitan protozoan parasite of felids that also has significant implications for the health of wildlife, livestock and humans worldwide. In Australia, feral, stray and domestic cats (Felis catus) are the most important definitive host of T. gondii as they are the only species that can excrete the environmentally resistant oocysts that provide a major source of infection for mammals and birds. In Tasmania, the rapid decline of the Tasmanian devil (Sarcophilus harrisii) may allow an increase in feral cat abundance, thereby increasing the risk of T. gondii infection to a range of susceptible wildlife species. At present, there is scant information on the prevalence of T. gondii infection in feral cat populations across Tasmania. We tested feral cats from 13 regions across Tasmania for the presence of T. gondii–specific IgG antibodies using a modified agglutination test. Results were combined with serosurveys from three previous studies to enable a comparison of seroprevalence among 14 regions across Tasmania. We found that 84.2% (224 of 266) of cats tested positive for T. gondii IgG antibodies. This is among the highest rates of prevalence recorded from Australia, and significantly higher than for most other countries. Adult cats had higher seroprevalence than kittens but there was no difference between sexes. In Tasmania, seroprevalence was high in 12 of 14 regions (range: 79.3–100.0%), with only two regions (Tasman Island and Southern Tasmania) recording significantly lower seroprevalence (≤50%). This suggests a high risk of infection across Tasmania, and has significant implications for wildlife conservation should feral cat abundance increase with the ongoing declines in Tasmanian devils.

AHYONG, SHANE T. "Preliminary diagnoses of three new species of Tasmanian mountain shrimps, Anaspides Thomson, 1894 (Syncarida, Anaspidacea, Anaspididae)." Zootaxa 3957, no. 5 (May 19, 2015): 596. http://dx.doi.org/10.11646/zootaxa.3957.5.8.
Full textAbstract:
The endemic Tasmanian mountain shrimps of the genus Anaspides Thomson, 1894 (Anaspidacea) have attracted considerable scientific interest as potential basal eumalacostracans and as 'living fossils', closely resembling their Triassic forbears (Coineau & Camacho 2013). Two species are currently recognised, with A. tasmaniae (Thomson, 1893) (type locality: Mount Wellington) accorded a wide range throughout most of central, western and southern Tasmania, and A. spinulae Williams, 1965, believed restricted to central Tasmania from Lake St. Clair (type locality) and immediate environs (O’Brien 1990). Despite the current taxonomy, heterogeneity in A. tasmaniae has been increasingly suggested, which may have important conservation management implications (e.g., Jarman & Elliot 2000). Jarman & Elliott (2000) recognised three potential clades (based on mitochondrial 16S sequences) that may correspond to separate species. A taxonomic and phylogenetic revision of the genus, now in progress, found A. tasmaniae to be restricted to the vicinity of Mount Wellington, and all Anaspides from other localities to represent other species. Owing to delays in the completion of the revision, however, some of the new species of Anaspides are briefly diagnosed below in order to make the formal species names available for other studies now underway. Full accounts of the species of Anaspides will be given when the revision of the genus is completed.

Full textAbstract:
In Tasmania, a considerable proportion of the forested landscape is available for land clearance and production forestry, which has and will continue to result in a decline in hollow availability unless managed appropriately. All hollow-using species are listed as having priority status under the Tasmanian Regional Forest Agreement. To ensure the habitat for hollow-using fauna is managed effectively, we first have to understand the requirements of the species involved. This paper is a review of the distribution, hollow requirements and conservation status of the five species of arboreal marsupials, eight species of bats and 29 bird species that use hollows in Tasmania. The number of species that use hollows is lower than in many other areas of Australia, but these species represent a large proportion of the vertebrate fauna of Tasmania. Three of these species and nine subspecies are endemic to Tasmania and seven are exotic. Four bird species are listed as Threatened at the state and/or national level. Twenty-five of Tasmania’s hollow-using species are capable of using small hollows, 14 can use medium-sized hollows and three bird species are limited to using large hollows. Current records indicate that the highest diversity of hollow-using species is associated with dry forest areas.

Full textAbstract:
Species of the genus Anaspides, known as mountain shrimps, are endemic to Tasmania and inhabit a variety of freshwater habitats such as mountain tarns, pools, creeks and runnels, as well as caves. Until 2015 only two species of Tasmanian mountain shrimps were recognized, A. tasmaniae (Thomson, 1893), which was believed to be widespread all over the island and A. spinulae from Lake St. Clair. Revision of the genus by Ahyong in 2016 recognized 7 species, most having narrow geographic distributions. Only two widespread species remained: A. richardsoni, occurring mainly on the Central Plateau and its margins, and A. swaini, occurring largely in south-western Tasmania. Notably, within A. swaini, three geographically correlated morphological forms were observed. We re-evaluated all three forms of A. swaini and herein describe one of the forms as a new species, A. driesseni, on the basis of morphological and molecular data. Anaspides driesseni corresponds to A. swaini form 3 and occurs mainly in south-eastern Tasmania from the Hartz Mountains over the Snowy Mountains to the Wellington Range. Telson structure, spination and male secondary sexual characters proved taxonomically instrumental.

Full textAbstract:
The paper examines the fall of marital fertility in Tasmania, the second settled Australian colony, in the late 19th and early 20th centuries. The paper investigates when marital fertility fell, whether the fall was mainly due to stopping or spacing behaviours, and why it fell at this time. The database used for the research was created by reconstituting the birth histories of couples marrying in Tasmania in 1860, 1870, 1880 and 1890, using digitised 19th century Tasmanian vital registration data plus many other sources. Despite Tasmania’s location on the other side of the world, the fertility decline had remarkable similarities with the historical fertility decline in continental Western Europe, England and other English-speaking countries. Fertility started to decline in the late 1880s and the fertility decline became well established during the 1890s. The fall in fertility in late 19th century Tasmania was primarily due to the practice of stopping behaviour in the 1880 and 1890 cohorts, although birth spacing was also used as a strategy by the 1890 cohort. The findings provide support for some of the prominent theories of fertility transition.

Hammer, Michael P., Mark Adams, Peter J. Unmack, and Keith F. Walker. "A rethink on Retropinna: conservation implications of new taxa and significant genetic sub-structure in Australian smelts (Pisces:Retropinnidae)." Marine and Freshwater Research 58, no. 4 (2007): 327. http://dx.doi.org/10.1071/mf05258.
Full textAbstract:
The smelt genus Retropinna nominally includes three small (<150 mm) freshwater fish species endemic to south-eastern Australia and New Zealand. For the two Australian species, the broad range of R. semoni (Weber) on the mainland suggests some vulnerability to isolation and genetic divergence, whereas the apparent confinement of R. tasmanica McCulloch to Tasmania is curious if, as suspected, it is anadromous. Analyses of Australian material using allozyme electrophoresis show five genetically distinct species with contiguous ranges and no evidence of genetic exchange. Three occur along the eastern seaboard (including three instances of sympatry), another in coastal and inland south-eastern Australia and Tasmania, and a fifth species in the Lake Eyre Basin. There is no indication of a simple ‘tasmanica’ v. ‘semoni’ dichotomy, but instead a complex pattern involving discrete clusters for the Upper Murray plus Darling rivers, Lower Murray, Glenelg River and Tasmanian regions, with coastal western Victorian samples having varying affinity to these groups. The overall pattern is one of deep divergences among species and strong genetic sub-structuring within and provides a strong argument for extended studies to prepare for appropriate conservation measures.

Full textAbstract:
The Tasmanian Wilderness World Heritage Area encompasses an area of 1.38 million hectares, or approximately 20% of the island state of Tasmania. The World Heritage Area plays a significant role in the conservation of Tasmania's fauna and natural biological processes. The area supports 30 species of terrestrial mammal including three endemic species (91% of total Tasmanian species), 120 species of terrestrial bird including 10 endemic species (76% of state total), 14 species of terrestrial reptile including seven endemic species (67% of state total), seven species of frog including three endemic species (64% of state total), 16 species of freshwater fish including four endemic species (64% of state total), and 68 species of marine fish including one endemic species (14% of state total). A number of vertebrate species are entirely restricted to the World Heritage Area (Moss Froglet, Pedra Branca Skink, Mountain Skink, Pedder Galaxias, Swamp Galaxias and Western Paragalaxias, while the migratory Orange-bellied Parrot breeds only within the World Heritage Area. A number of other species have the majority of their Tasmanian range within the World Heritage Area (Broad-toothed Rat, Ground Parrot, Southern Emu-wren, Tasmanian Tree Frog, Northern Snow Skink, Southern Snow Skink, Bathurst Harbour Skate and the Clarence Galaxias). The World Heritage Area also supports a range of threatened mammal, bird, reptile and fish species. Of the 44 species of introduced vertebrates which have established feral populations in Tasmania, only seven species (16% of state total) have a significant presence within the World Heritage Area and pose a potential threat to the area's integrity. The diversity and endemism of the vertebrate fauna of the World Heritage Area reflects the Gondwanan origins of much of the fauna of western Tasmania, the repeated glaciation of the area during the Pleistocene, and subsequent pulses of speciation among certain taxa.

Full textAbstract:
The restricted distribution of viviparous onychophorans in Tasmania has long been a subject of discussion, but their evolutionary history remains unclear. We applied morphological, molecular and karyological methods to assess the taxonomy and phylogenetic relationships of the four viviparous species reported from Tasmania, including Tasmanipatus barretti, T. anophthalmus and two undescribed species previously referred to as ‘Tasmania’ sp. 1 and sp. 2. We demonstrate that all four species can be unambiguously distinguished based on independent character sets. The two ‘Tasmania’ species, which were previously thought to be cryptic, proved to exhibit a set of distinct morphological characters. Molecular phylogenetic analyses revealed that the four species belong to a major clade that includes Peripatoides from New Zealand, and that species from the two landmasses show reciprocal monophyly within this clade. Within the Tasmanian clade, T. anophthalmus is more closely related to the two ‘Tasmania’ species than to T. barretti. Based on this relationship and the lack of morphological and/or karyological characters supporting the Tasmanian viviparous clade, we erect two new genera to accommodate the two ‘Tasmania’ species (Diemenipatus, gen. nov.) and T. anophthalmus (Leucopatus, gen. nov.). An emended diagnosis followed by a redescription of T. barretti is provided and ‘Tasmania’ sp. 1 and sp. 2 are formally described as D. taiti, gen. et sp. nov. and D. mesibovi, gen. et sp. nov., respectively.

Full textAbstract:
The term ‘snow patch’ indicates an area in an alpine zone with distinct vegetation because snow persists there longer than in the surrounding areas. Snow patches are a well known rare and threatened ecosystem on mainland Australia, but little is known of their distribution and vegetation in Tasmania. We describe, and determine the environmental relationships of, snow patches and their vegetation in Tasmania. There are 119 snow patches in Tasmania, covering 86 ha in toto, 43 of which have some fjaeldmark vegetation and the rest of which have a complete vegetation cover. Snow patches are confined to the taller, more continental mountains where they occur on north-east- to east-facing slopes, with the surrounding alpine vegetation usually being free of persistent snow. Their considerable floristic and structural variability relates to substrate and climate. Within Tasmania, several species are largely restricted to snow patches. The high degree of Tasmanian endemism in the snow-patch vegetation makes it distinct from the snow-patch vegetation of mainland Australia. The Tasmanian snow patches are also distinct in their environmental conditions. In Tasmania, snow does not usually persist over the winter outside the 119 snow patches. There are five floristic communities in these patches, all being distinct from those in mainland Australian snow patches. The Tasmanian snow patches merit listing as a threatened ecosystem on the basis of their distinctiveness and restricted extent.

White, Lauren C., and Jeremy J. Austin. "Relict or reintroduction? Genetic population assignment of three Tasmanian devils ( Sarcophilus harrisii ) recovered on mainland Australia." Royal Society Open Science 4, no. 4 (April 2017): 170053. http://dx.doi.org/10.1098/rsos.170053.
Full textAbstract:
Today, the Tasmanian devil ( Sarcophilus harrisii ) is found only on the island of Tasmania, despite once being widespread across mainland Australia. While the devil is thought to have become extinct on the mainland approximately 3000 years ago, three specimens were collected in Victoria (south-eastern Australia) between 1912 and 1991, raising the possibility that a relict mainland population survived in the area. Alternatively, these devils may have escaped captivity or were deliberately released after being transported from Tasmania, a practice that has been strictly controlled since the onset of devil facial tumour disease in the early 1990s. Such quarantine regimes are important to protect disease-free, ‘insurance populations’ in zoos on the mainland. To test whether the three Victorian devils were members of a relict mainland population or had been recently transported from Tasmania we identified seven single nucleotide polymorphisms (SNPs) in the mitochondrial genome that can distinguish between Tasmanian and ancient mainland populations. The three Victorian devil specimens have the same seven SNPs diagnostic of modern Tasmanian devils, confirming that they were most likely transported from Tasmania and do not represent a remnant population of mainland devils.

Some thelotremoid lichens of Tasmania are reviewed. The following new combinations are proposed: Gintarasia asteliae (Kantvilas & Vĕzda) Kantvilas, G. minor (Kantvilas & Vĕzda) Kantvilas and G. tasmanica (Kantvilas & Vĕzda) Kantvilas. A revised description of Schizotrema schizolomum (Müll.Arg.) Mangold & Lumbsch, based on Tasmanian collections, is provided, and the new species, S. vezdanum Kantvilas, recorded from Tasmanian and Victoria, is described and illustrated; it is characterised by a thallus containing stictic acid, 8-spored asci, and non-amyloid, muriform ascospores, 22−44 × 9−18 µm. Schizotrema guadeloupense (Hale) Mangold & Lumbsch is deleted from the Tasmanian census. Also described as new and illustrated is the Tasmanian endemic, Topeliopsis fatiscens Kantvilas, characterised by a thallus containing salazinic acid, (1−)2(−3)-spored asci and strongly amyloid, muriform ascospores, 37−100 × 19−40 µm. Thelotrema lepadodes var. endochrysoides Jatta is identified as a synonym of the cosmopolitan species T. lepadinum (Ach.) Ach.

AbstractThe genus Coenogonium Ehrenb. in Tasmania comprises seven species. New to science are: C. atherospermatis Kantvilas, Rivas Plata & Lücking, endemic to Tasmania and characterized by pale yellowish beige apothecia and relatively small ascospores, 6–8·5×2·5–3 µm; C. urceolatum Kantvilas, Rivas Plata & Lücking, likewise endemic to Tasmania and characterized by orange, urceolate apothecia, 0·3–0·4 mm wide, and uniseriate ascospores, 8·5–11×2·5–3 µm; and C. australiense Kantvilas & Lücking, recorded from Tasmania, South Australia and New South Wales, and characterized by orange apothecia, 0·5–2 mm wide, and relatively broad ascospores, 10–14×3–4·5 µm. Also treated are C. lutescens (Vĕzda & Malcolm) Malcolm (Tasmania and New Zealand) and three widespread taxa, namely C. implexum Nyl. (Southern Hemisphere), C. luteum (Dicks.) Kalb & Lücking and C. pineti (Schrad. ex Ach.) Lücking & Lumbsch (both subcosmopolitan). All species are described in full from Tasmanian collections and illustrated, and their ecology, variation and affinities to related species are discussed. The Tasmanian taxa are also discussed in the context of the Australasian lichen biota.

Full textAbstract:
Compared with mainland Australia the diversity of rodents in Tasmania is low. In all, there are five species of native rodent in Tasmania. Three species – the water rat, Hydromys chrysogaster, the long-tailed mouse,Pseudomys higginsi and the swamp rat, Rattus lutreolus – are widely distributed. The broad-toothed rat, Mastacomys fuscus, is restricted to moorlands in western Tasmania, while the New Holland mouse, Pseudomys novaehollandiae, is restricted to coastal heath in north-eastern Tasmania and is listed as Rare under Tasmania’s Threatened Species Protection Act 1995. Only one species, Pseudomys higginsi, is endemic to Tasmania. Rattus lutreolus velutinus and Mastacomys fuscus fuscus are endemic subspecies. In addition to the native rodents, three species of exotic rodents are well established in Tasmania.

Full textAbstract:
Dermosols (24%) and Organosols (14.8%) are the dominant soil orders in Tasmania, with the mapped occurrence of >985 000 ha of Organosols in Tasmania being the greatest in any Australian State. Tenosols and Rudosols are well represented in all 3 natural resource management (NRM) regions and Kurosols are more prevalent in the NRM North and South Regions. Tasmania has a greater proportion of Ferrosols (8.4%) than the whole of Australia (0.8%) and these soils are some of the most productive in Tasmania with >25 000 ha used for cropping. Hydrosols (3.7%) are probably underestimated. Chromosols (5.3%) and Sodosols (1.6%) are relatively minor soils in Tasmania, occurring predominantly in lower rainfall areas with <800 mm average annual rainfall. Parent material is a strong determinant of soil distribution in Tasmania but many Soil Orders occur on a wide range of parent materials. Brown suborders are predominant in several Soil Orders. A large part of Tasmania (2 658 000 ha) is mapped as being used for conservation, with one-third of this area being mapped as Organosols. The mean surface horizon soil carbon content (4.3%) is relatively high, likely due to Tasmania’s relatively high annual rainfall and cool temperatures. Most Soil Orders have moderately acid surface horizons but soils on calcareous parent materials are neutral to strongly alkaline (Tenosols and Calcarosols). The dataset covers the mainland extent of Tasmania, as well as all large islands around Tasmania’s coastline including King, Flinders, Hunter, Three Hummock, Robbins, Cape Barren, Clarke, and Maria Islands.

Full textAbstract:
We review literature pertaining to the distribution, habitat and conservation status of the eastern pygmy-possum Cercartetus nanus in Tasmania. Records from fauna surveys, museum specimens, and the Tasmanian Natural Values Atlas database, suggest that although C. nanus is widespread, it occurs in low numbers in Tasmania. From 51 fauna surveys examined, only 19 C. nanus were detected in a total of 47,087 Elliott trap-nights, 5,665 pitfall trap-nights, 196 scats or owl pellets, 899 spotlight hours, and 86 predator stomachs. A total of 102 Tasmanian C. nanus specimens was located in Australian and overseas museums. These records combined with 23 from the Natural Values Atlas database and 61 from an earlier published collation represent 99 of 679 grid squares (10 km x 10 km) overlaid across Tasmania (including King Island and Flinders Island). The patchy distribution of these records may be a reflection of low survey effort, low population numbers, low detectability or a combination of these and other factors. The highest number of records for a single locality was only four. Available data suggest that Tasmanian populations may be small and therefore potentially at risk from habitat loss, inappropriate fire regimes, and firewood collection. We believe there is a pressing need for further surveys to more clearly define the conservation status of C. nanus in Tasmania.

Full textAbstract:
Tasmania is the only state in Australia which is not supplied with natural gas, and yet a significant gas, condensate and oil resource lies off the Tasmanian coast awaiting development.The Yolla field, discovered by Amoco, SAGASCO Resources, the Bass- Cue Group, Romsey Resources and Southeastern Petroleum in 1985, has sufficient resource potential to support the development of a natural gas supply infrastructure in Tasmania. The field is rich in LPG and condensate and also contains a small oil pool. Tests on the Yolla 1 well were the first in the Bass Basin to flow hydrocarbons and they demonstrated that the field has excellent reservoir properties for commercial development.The keys to the initiation of a gas, condensate and oil development in Tasmania are the need for a significant market for the natural gas and an oil price somewhat better than US$20 per barrel. While there are many major manufacturing and mineral processing plants on the Tasmanian North Coast which would benefit from the stimulus provided by a reliable natural gas pipeline supply, these industries alone provide insufficient load to make an offshore gas development economic. The Bell Bay power station, a thermal power station of 240 MW capacity fired on fuel oil, could, if converted to gas and operated to provide base load supply, generate sufficient base gas demand to enable a project development to proceed.A gas condensate development would provide a substantial stimulus to the Tasmanian economy through:direct investment in the project itself;fostering further development of processing industries on the North Coast;providing cheaper electricity than available from new hydroelectric and coal fired stations;contributing significantly to Tasmanian self- sufficiency in liquid fuels; andreleasing scarce government capital for debt reduction or other uses.

Full textAbstract:
The eastern barred bandicoot, Perameles gunnii, formerly occurred widely in Victoria and Tasmania. Because it is endangered in Victoria, clarification of its conservation and taxonomic status in Tasmania is important. We observed the distribution and relative abundance of Perameles gunnii in nine localities in Tasmania. Comparisons of trappability in three localities sampled in March 1985 and October- November 1989 showed no decline in relative abundance. P. gunnii were more abundant in November 1989 than on two previous occasions at one location. However, six other localities where P. gunnii were abundant in 1985 showed little evidence of P. gunnii activity in 1989. Spotlighting and trapping efforts, together with anecdotal information, suggest a decline in the status of P. gunnii in the Tasmanian Midland region. The reduction of these populations could be a feature of normal demographic fluctuation or could be indicative of a real decline in the status of P. gunnii. Long-term studies to monitor seasonal and annual abundance changes in Tasmania would be useful for the management of the dwindling Victorian population, and are needed to fully determine the status of Tasmanian populations for conservation and management purposes.

Full textAbstract:
The variation in selected leaf morphological traits was examined across the geographic ranges of two Tasmanian rainforest species, Tasmannia lanceolata (Poiret) A.C.Smith and Eucryphia milliganii Hook.f. Comparisons of field- and glasshouse-grown plants for both species showed that there is strong genetic control of all the morphological characters measured. Two distinct morphotypes, occupying similar areas of Tasmania, were identified in each species. The geographic boundary between the morphotypes is similar in both species and runs more or less east–west, separating each species into northern and southern forms. Southern E. milliganii differs from the northern form in having ovate leaves with dense marginal trichomes and a pubescent abaxial leaf lamina. A new subspecies, E. milliganii ssp. pubescens, is described to encompass this intra-specific variation in southern Tasmania. Southern T. lanceolata has encrypted stomata, contrasting with the superficial stomata of the northern form, but is not considered sufficiently different to warrant separate taxonomic status. The boundary is difficult to explain in terms of modern environmental factors. A past period of significantly different climate from the present, perhaps combined with anthropogenic fire regimes, may have enabled allopatric differentiation within each species.

Full textAbstract:
Patterns of genetic and morphological divergence were examined among Western Australian (Abrolhos Islands and Albany) and Tasmanian members of the highly variable 'Austrocochlea constricta' species complex. Analyses of allele frequencies at 13 enzyme loci confirmed the presence of three species within this complex in Tasmania, revealing additional diagnostic differences not previously detected. Where combinations of species sympatry were examined in Tasmania, seven diagnostic loci separated A. constricta and A. brevis, four separated A. porcata and A. brevis, and one separated A. porcata and A. constricta. Western Australian animals were genetically most similar to Tasmanian A. constricta populations, separated from them by genetic distances of just 0.018 (Albany) to 0.107 (Abrolhos), despite spatial isolation over ~3000 km. These genetic distances, in addition to that separating Abrolhos and Albany populations (0.138), are considered within the range possible for allopatric conspecifics. In comparison, genetic distances separating A. constricta from sympatric A. porcata (0.191) and A. brevis (0.803) in Tasmania were much larger. However, on the basis of a range of morphological traits, which were species-diagnostic in Tasmania, Abrolhos animals most closely resembled A. porcata, and Albany animals appeared intermediate to A. porcata and A. constricta. This suggests Australia-wide discordance among genetic and morphological characters of the 'A. constricta' complex.

AbstractWith 30 species, Tasmania is a major area of species diversity in the genus Menegazzia. Seven of these are new to science: M. abscondita Kantvilas, known from Tasmania and New Zealand, and M. athrotaxidis Kantvilas, M. hypogymnioides Kantvilas, M. petraea Kantvilas, M. ramulicola Kantvilas, M. subtestacea Kantvilas and M. tarkinea Kantvilas, all endemic to Tasmania. An identification key, descriptions based exclusively on Tasmanian collections, and detailed discussion of distribution, ecology, chemical composition and inter-species relationships are provided. All literature records of Menegazzia species pertaining to Tasmania are accounted for. New synonyms include: Menegazzia prototypica P. James and Parmelia pertusa var. coskinodes F. Wilson [synonyms of M. myriotrema (Müll. Arg.) R. Sant.], M. fertilis P. James [a synonym of M. platytrema (Müll. Arg.) R. Sant.] and Parmelia pertusa var. montana F. Wilson (a synonym of M. subtestacea). Incorrectly recorded species that should be deleted from the Tasmanian census include M. castanea P. James & D. J. Galloway (present on Macquarie Island) and M. testacea P. James & D. J. Galloway (endemic to New Zealand). The South American species, M. sanguinascens (Räs.) R. Sant., is recorded in Australasia (Tasmania) for the first time, whereas the widespread south-eastern Australian M. norstictica P. James is recorded for Western Australia. Salient features of the genus are discussed, including morphology, anatomy and chemistry. The biogeography of the genus is explored briefly. Twelve species (40%) are endemic to Tasmania, a level of endemism unmatched by any other species-rich genus on the island. Twelve species are shared with mainland Australia, eleven are shared with New Zealand, and only four species are shared with southern South America, all of which are sorediate, suggesting they are products of long-distance dispersal.

"Genetic structure and new occurrence records of the iconic Tasmanian mountain shrimp Anaspides tasmaniae (Thomson, 1893) (Anaspidesidae : Anaspidacea) reveal relictual distribution in southern Tasmania." Australian Journal of Zoology 68, no. 1 (2020): 45. http://dx.doi.org/10.1071/zo20100.
Full textAbstract:
The iconic ‘mountain shrimps’ of the genus Anaspides Thomson, 1894, are endemic to Tasmania, inhabiting various freshwater habitats such as mountain tarns and creeks, as well as streams inside caves. They are often labelled as ‘living fossils’ because of their close resemblance to their Triassic relatives. Prior to 2015, only two species were recognised but recent studies have uncovered a total of at least seven species. The type species of Anaspides, A. tasmaniae (Thomson, 1893), was previously believed to occur throughout Tasmania, but following a review in 2016, this species was confirmed only from a small range on the east and south-east side of Mt Wellington, with Anaspides from other parts of Tasmania referable to other species. We herein provide a detailed assessment of the distribution and genetic structure of A. tasmaniae based on extensive field surveys throughout the ranges of all species of Anaspides. The distribution of A. tasmaniae is extended to include four separate localities in and around the Mt Field National Park, 50 km north-west of Mt Wellington. The recovered genetic structure of A. tasmaniae based on 48 specimens indicates that the disjunct distribution is unlikely to be the result of artificial translocation but, instead, probably reflects postglacial relictualisation of a formerly continuous range present during Pleistocene glacial maxima. Of particular interest is the record of syntopy in Anaspides, observed at the entrance of Khazad Dum cave, where both A. tasmaniae and A. swaini inhabit the inflow stream.

Full textAbstract:
Abstract. Thirty-six borehole temperature–depth profiles were analysed to reconstruct the ground surface temperature history (GSTH) of eastern Tasmania for the past 5 centuries. We used the singular value decomposition method to invert borehole temperatures to produce temperature histories. The quality of borehole data was classified as high or low based on model misfit. The quality of the borehole data was not dependent on topography or land use. Analysis reveals that three to five high-quality borehole temperature–depth profiles were adequate to reconstruct robust paleotemperature records from any area. Average GSTH reconstructed from Tasmanian boreholes shows temperature increases about 1.2 ± 0.2 °C during the past 5 centuries. Reconstructed temperatures were consistent with meteorological records and other proxy records from Tasmania during their period of overlap. Temperature changes were greatest around the north-east coast and decreased towards the centre of Tasmania. The extension of the East Australian Current (EAC) further south and its strengthening around the north-east coast of Tasmania over the past century was considered a prime driver of warmer temperatures observed in north-east Tasmania.

Australian Journal of Botany 55, no. 5 (2007): 513. http://dx.doi.org/10.1071/bt06203.
Full textAbstract:
Eucalyptus perriniana F.Muell. ex Rodway is distributed over a wide geographic range in south-eastern Australia as a series of small and isolated populations. In Tasmania, there are only three known populations that are separated by 511 km from the closest population on mainland Australia, which is one of the largest disjunctions observed for any eucalypt species. This project utilised eight nuclear microsatellites and one chloroplast DNA marker to study the genetic diversity in E. perriniana and determine the affinities between the populations. In all, 302 individuals in nine populations across the whole range of the species were sampled. The overall nuclear microsatellite diversity in E. perriniana (Ht = 0.85), as well as the diversity in each population (He = 0.73), was comparable to that found in widespread eucalypt species that have much larger population sizes. The microsatellites revealed that the isolated Tasmanian populations were significantly differentiated from mainland populations (FST between regions = 0.08), although the mainland Baw Baw population was the most differentiated. Most populations harboured different chloroplast DNA haplotypes, but in general, there were more mutational differences among haplotypes found in Tasmania than between Tasmanian and mainland populations. The Tasmanian populations often shared chloroplast DNA haplotypes with other eucalypts from south-eastern Tasmania. In conclusion, the populations of E. perriniana are genetically variable and significantly differentiated, with geographic separation being a poor predictor of the amount of genetic divergence. The most divergent populations are those in Tasmania and on Mt Baw Baw and their conservation is important to capture the genetic diversity in the species.

Full textAbstract:
Warriors in the history wars’ do battle over the accuracy and portrayal of Aboriginal history in Tasmania, but for the descendants of the traditional people this contested field is also the site of our families’ stories. This paper juxtaposes, via the woven narrative of Woretemoeteryenner, a personal perspective against the history wars sterile dissection of official records. Woretemoeteryenner’s story serves as a personalising frame for Tasmanian colonial history. Born before the beginning of European colonisation, by the end of her life fewer than 50 traditional Tasmanians remained. Her story also shines a light on the lived experiences of that small group of Aboriginal women who form the link between the traditional people and present Tasmanian Aboriginal communities. Most critically, Woretemoeteryenner’s life is a personal story of a life lived through these now disputed and debated times.

Full textAbstract:
: The narrator of Christopher Koch's 1958 novel The Boys in the Island claims for Tasmania “a different soul”, distinct from that of the Australian mainland to the north, in the same breath in which he claims for the island “a different weather”. Observations of the distinctiveness of island geography and weather – and of the quality of the light – are recurrent in narratives set not only in Tasmania, but also on those islands to which Tasmania itself acts as a ‘mainland’. This paper surveys a range of texts, including Koch’s The Boys in the Island, Joanna Murray-Smith’s Truce, and my own The Alphabet of Light and Dark, in which a Tasmanian island functions both as a setting for the protagonist's idealized childhood and as a metaphor for the protagonist’s “true self”. It explores the representation of islands in these texts, examining how a specific tradition of writing about Tasmania intersects with a broader tradition of writing about islands.

Full textAbstract:
Seventy nine sightings of Leopard Seals, Hydrurga leptonyx, made over a period of 7 years in Tasmania are reported. They show that the species occurs annually in Tasmanian waters between July and November, probably as a result of northward movement from the Antarctic pack ice zone. Its seasonal occurrence in Tasmanian waters implies that it is a regular member of the marine fauna of the region. This is in contrast to previous reports that the species was a rare vagrant, occasionally stranding along the coastline. Comparisons of the age structure of H. leptonyx in Tasmania with those on subantarctic islands suggests that there is a clinal variation with latitude in the dispersal pattern, as young animals disperse further north than adults.

Full textAbstract:
The short-beaked echidna is the most widely distributed endemic Australian mammal, and echidnas from different geographic areas differ so much in appearance that they have been assigned to several subspecies. In this paper, we present data obtained from free-ranging echidnas in southern Tasmania, and compare this with studies from other parts of Australia. In Tasmania mating occurs between early June and mid-September, and throughout Australia the normal breeding season lies within these limits. In echidnas from the more easterly parts of Australia reproduction closely follows hibernation, with Tasmanian echidnas showing a significant overlap between hibernation and reproduction. There is intense competition between males, and female echidnas from Tasmania show multiple matings. There are significant differences between echidnas from different areas of Australia in the use of nursery burrows and maternal care. One of the most dramatic differences is in duration of lactation: echidnas from Kangaroo Island wean the young at 204–210 days, but in Tasmania weaning occurs at 139–152 days, even though the masses of the young at weaning are comparable.

Center for Accelerator Mass Spectrometry (CAMS) Tasmanian Huon pine (Lagarostrobos franklinii) decadal measurements for the interval AD 745–855 suggest a mean interhemispheric radiocarbon offset (20 ± 5 yr), which is considerably lower than the previously reported mean interhemispheric offset for the last 2 millennia (44 ± 17 yr). However, comparable University of Waikato (Wk) New Zealand kauri (Agathis australis) measurements show significantly higher values (56 ± 6 yr), suggesting the possibility of a temporary geographic (intrahemispheric) offset between Tasmania, Australia, and Northland, New Zealand, during at least 1 common time interval. Here, we report 9 new Wk Tasmanian Huon pine measurements from the decades showing the largest Huon/kauri difference. We show statistically indistinguishable Wk Huon and Wk kauri 14C ages, thus dispelling the suggestion of a 14C geographic offset between Tasmania and Northland.

Full textAbstract:
AbstractIn the language of the Tebrikunna (Cape Portland) clan, Carne Neemerranner is “telling ground”. It is also what we call the research methodology designed for Meeting at Bark Hut, a recent community-engaged Aboriginal history project conducted in northeast Tasmania. The project examined, retraced and explored one brief, but poignant, episode in Tasmania's colonial contact history – a meeting between the parties of George Augustus Robinson, colonial agent charged with the “conciliation” and removal of Trouwunnan (Tasmanian) clanspeople from the Tasmanian mainland, and that most likely included Mannalargenna, one of the last Trouwunnan leaders still living in his own clancountry at the time (1830). While this episode and encounter has profound connotations for presentday Tasmanian Aborigines, its significance has largely been overlooked by academic historians. Meeting at Bark Hut was conceived as an opportunity to redress this deficit, to allow the story of this event to be told and to come alive in a dynamic and culturally relevant way. This article offers some insight into the meaning and method of the project from both theoretical and practical perspectives.

Full textAbstract:
Sedimentary successions belonging to three petroleum su persy stems can be recognised in and below the Late Carboniferous to Late Triassic onshore Tasmania Basin. These are the Centralian, Larapintine and Gondwanan. The oldest (Centralian) is poorly known and contains possible mature source rocks in Upper Proterozoic dolomites. The Larapintine 2 system is represented by rocks of the Devonian fold and thrust belt beneath the Tasmania Basin. Potential source rocks are micrites and shales within the 1.8 km-thick tropical Ordovician Gordon Group carbonates. Conodont CAI plots show that the Gordon Group lies in the oil and gas windows over most of central Tasmania and probably under much of the Tasmania Basin. Potential reservoirs are the upper reefal parts of the Gordon Group, paleokarsted surfaces within the Gordon Group and the overlying sandstones of the Siluro-Devonian Tiger Range and Eldon Groups. Seal rocks include shales within the Siluro-Devonian and Upper Carboniferous-Permian tillites and shales.The Gondwanan supersystem is the most promising supersystem for petroleum exploration within the onshore Tasmania Basin. It is divided into two petroleum systems— the Early Permian Gondwanan 1 system, and the Late Permian to Triassic Gondwanan 2 system. Excellent source rocks occur in the marine Tasmanite Oil Shale and other sections within the Lower Permian Woody Island and Quamby Formations of the Gondwanan 1 system and within coals and freshwater oil shales of the Gondwanan 2 system. These sources are within the oil and gas windows across most of the basin and probably reached peak oil generation at about 100 Ma. An oil seep, sourced from a Tasmanites-rich, anoxic shale, is found within Jurassic dolerite 40 km WSW of Hobart. Potential Gondwanan 1 reservoirs are the glaciofluvial Faulkner Group sandstones and sandstones and limestones within the overlying parts of the glaciomarine Permian sequence. The Upper Permian Ferntree Mudstone Formation provides an effective regional seal. Potential Gondwanan 2 reservoirs are the sandstones of the Upper Permian to Norian Upper Parmeener Supergroup. Traps consisting of domes, anticlines and faults were formed probably during the Early Cretaceous. Preliminary interpretation of a short AGSO seismic profile in the Tasmania Basin shows that, contrary to earlier belief, structures can be mapped beneath extensive and thick (300 m) sills of Jurassic dolerite. In addition, the total section of Gondwana to Upper Proterozoic to Triassic sediments appears to be in excess of 8,500 m. These recent studies, analysis of the oil seep and drilling results show that the Tasmanian source rocks have generated both oil and gas. The Tasmania Basin is considered prospective for both petroleum and helium and is comparable in size and stratigraphy to other glaciomarine-terrestrial Gondwanan basins such as the South Oman and Cooper Basins.

Full textAbstract:
Knowledge of the habitat requirements of nocturnal birds is vital for the development of effective conservation strategies. This study is the first intensive systematic survey of the occurrence of the threatened Tasmanian masked owl (Tyto novaehollandiae castanops), the Tasmanian boobook (Ninox leucopsis) and the Australian owlet-nightjar (Aegotheles cristatus) in Tasmania using call playback, spotlighting and listening techniques. Occupancy models were created that explain the spatial distribution of the three species. Temperature and wind influenced the detectability of all species. Detectability of the Tasmanian boobook was also associated with nightlight. The Tasmanian masked owl was most often found in low-elevation mature dry eucalypt forest. This may be related to a combination of availability of nesting sites, food availability and accessibility, and physiological factors. The Australian owlet-nightjar also showed a broad preference for dry eucalypt forest and avoided open country. In contrast, the Tasmanian boobook was most often found in wet eucalypt forest with higher temperatures and fewer roads. We conclude that mature dry and wet forest types at low elevations need to be carefully managed to maintain populations of Tasmania’s nocturnal birds, particularly the threatened Tasmanian masked owl. Consideration should be given to retention of a network of contiguous areas of undisturbed mature forest across forested landscapes.

The Tasmanian devil ( Sarcophilus harrisii ) was widespread in Australia during the Late Pleistocene but is now endemic to the island of Tasmania. Low genetic diversity combined with the spread of devil facial tumour disease have raised concerns for the species’ long-term survival. Here, we investigate the origin of low genetic diversity by inferring the species' demographic history using temporal sampling with summary statistics, full-likelihood and approximate Bayesian computation methods. Our results show extensive population declines across Tasmania correlating with environmental changes around the last glacial maximum and following unstable climate related to increased ‘El Niño–Southern Oscillation’ activity.

Full textAbstract:
Through European colonization, First Nations peoples were subjected to systematic and violent actions to dispossess them of their land and sovereignty. In Tasmania, this involved government-sponsored bounties as well as militaristic and diplomatic efforts to remove Indigenous peoples from the landscape. At the same time, and using similar rhetoric, thylacines ( Thylacinus cynocephalus (Harris, 1808)) suffered similarly from settler colonists. Thylacines (also known as Tasmanian tigers or Tasmanian wolves) were the largest marsupial carnivores of modern times, but became extinct in the twentieth century. There are several parallels between the treatment and representation of thylacines and Indigenous Tasmanian people, and how their remains were traded. This allows for analysis of how the environmental and human costs of the colonial project were enmeshed with practices of natural history. A central figure in the export of both thylacines and Indigenous remains from Tasmania was Morton Allport (1830–1878). This paper shows that Allport actively built his scientific reputation by exchanging specimens for honours. It asks whether this was a widespread model for other colonial figures who may have used specimen-based philanthropy to develop a form of soft power through associations with respected institutions such as learned societies, universities and museums. Figures like Allport played the role of a type of colonial settler-intermediary, valued for providing privileged access to specimens to the metropole. Allport also worked to augment scientific work in Tasmania and the economic reputation of the colony, demonstrating that the development of social networks and scientific reputations of colonial figures were entwined with the status and success of the colonies themselves.

Apteropanorpa Carpenter, 1941 is a genus of scorpionflies endemic to Tasmania. The genus comprised two described species before the current study. However, many anecdotal reports suggested that Apteropanorpa was more widespread in Tasmania than had previously been thought, and that more species awaited discovery and description. Intensive field surveys for the Apteropanorpidae were conducted from 2001 to 2003 in a range of altitudes and habitats all over Tasmania. These surveys yielded a large number of adult specimens, collected at many new localities and at a range of elevations. Cladistic analyses of COI molecular and morphological data were congruent in their inferred species composition of the family. Phylogenetic analyses with evaluation of species concepts provided evidence for two new species: Apteropanorpa warra, sp. nov. and A. hartzi, sp. nov. The distribution of the Apteropanorpidae is much more extensive than was previously thought; many populations discovered as part of this research represent extensions of the known ranges of A. evansi Byers & Yeates and A. tasmanica Carpenter. A key to species is presented. The altitudinal range of each species is closely associated with the local climatic treeline. Hypotheses concerning the biogeography of the family are consistent with the glacial history of Tasmania.

Abstract Interannual rainfall variability over Tasmania is examined using observations and reanalysis data. Tasmanian rainfall is dominated by an east–west gradient of mean rainfall and variability. The Pacific–South American mode (PSA), El Niño–Southern Oscillation (ENSO), and the southern annular mode (SAM) each show clear influences on the interannual variability of Tasmanian rainfall. Composites of rainfall during each phase of ENSO and the PSA suggest a notable islandwide influence of these climate modes on Tasmanian rainfall. In contrast, the positive phase of the SAM is associated with drier conditions over the west of the island. The PSA and the SAM project most prominently over the southwest of the island, whereas the ENSO signature is strongest in the north. Empirical orthogonal functions (EOFs) of rainfall over Tasmania show a leading mode (explaining 72% of total variance) of coherent islandwide in-phase anomalies with dominant periods of 2 and 5 yr. The second EOF accounts for ∼14% of total variation, characterized by out-of-phase east–west anomalies, which is likely a combination of all three modes. The EOF1 mode can be attributed to ENSO, the PSA, and to a lesser extent the SAM.

The objective of this research is to identify the key selection criteria that form the basis of a shipper’s selection of freight transport mode. The study is undertaken in the context of sea freight. The study is localised to Tasmanian shippers who are, or are potentially, recipients of freight subsidisation through the Tasmanian Freight Equalisation Scheme. Data collected through an internet-based survey is described, and influential mode choice selection criteria are reported with the use of descriptive statistics. The findings indicate that Tasmanian shippers are conscious of cost, service, and cargo characteristics.Median responses indicate that cost, service, and cargo are equally significant in the selection process. The findings indicate that cost and cost flexibility are influential cost-based criteria. The findings also indicate that transit time, service capacity, and service flexibility are influential service-based criteria. Shipment size, cargo weight, and cargo volume are also identified as influential cargo-based criteria.This study provides insight into mode choice selection for Tasmanian shippers. In this function, it may assist existing air and sea carriers operating in the Tasmanian market to evaluate their performance and strategy by providing an analysis of shippers’ transport mode choice process. Tasmanian shippers themselves may benefit from the potential expansion of their existing freight transport mode choice process. New shippers of freight into and out of Tasmania may benefit from the perspectives of existing shippers of freight into and out of Tasmania.

Abstract. Changes to streamflows caused by climate change may have major impacts on the management of water for hydro-electricity generation and agriculture in Tasmania, Australia. We describe changes to Tasmanian surface water availability from 1961–1990 to 2070–2099 using high-resolution simulations. Six fine-scale (∼10 km2) simulations of daily rainfall and potential evapotranspiration are generated with the CSIRO Conformal Cubic Atmospheric Model (CCAM), a variable-resolution regional climate model (RCM). These variables are bias-corrected with quantile mapping and used as direct inputs to the hydrological models AWBM, IHACRES, Sacramento, SIMHYD and SMAR-G to project streamflows. The performance of the hydrological models is assessed against 86 streamflow gauges across Tasmania. The SIMHYD model is the least biased (median bias = −3%) while IHACRES has the largest bias (median bias = −22%). We find the hydrological models that best simulate observed streamflows produce similar streamflow projections. There is much greater variation in projections between RCM simulations than between hydrological models. Marked decreases of up to 30% are projected for annual runoff in central Tasmania, while runoff is generally projected to increase in the east. Daily streamflow variability is projected to increase for most of Tasmania, consistent with increases in rainfall intensity. Inter-annual variability of streamflows is projected to increase across most of Tasmania. This is the first major Australian study to use high-resolution bias-corrected rainfall and potential evapotranspiration projections as direct inputs to hydrological models. Our study shows that these simulations are capable of producing realistic streamflows, allowing for increased confidence in assessing future changes to surface water variability.

<p>The notion of food security encompasses the ability of individuals, households and communities to acquire food that is healthy, sustainable, affordable, appropriate and accessible. Despite Australia’s current ability to produce more food than required for its population, there has been substantial evidence demonstrating that many Australians struggle to feed themselves, particularly those from a cultural and linguistically diverse (CALD) background. This qualitative phenomenological study investigated the experiences of food security among migrants in a regional area of Australia (Tasmania).</p> <p>33 semi-structured interviews were conducted with Tasmanian migrants. The interviews were analysed thematically using Nvivo 10.0 and three main themes emerged: (1) migrant’s experiences of food security in Tasmania; (2) the factors that influence migrant food security in Tasmania; and (3) acculturation strategies. Participants were satisfied with their current food security in Tasmania but they still encountered some challenges in the availability, accessibility and affordability of healthy and cultural food. Factors that influenced their food security were educational background, the language barrier, socioeconomic status, geographical isolation, and their cultural background. Migrants managed to adapt to the new food culture by using different acculturation strategies.</p> <p>Migrants residing in Tasmania encounter a diverse number of challenges pertaining to food security and use different food security strategies while acculturating to the new environment. These findings may inform other migrant communities in Australia, relevant non-government organisations and government departments and suggest strategies to address food security challenges among migrants.</p>
