Can kangaroos survive in the wheaibelt? mm mmmm By Graham Arnold, Senior Principal Research Scientist, CSIRO Division of Wildlife and Ecology, Helena Valley One of the costs of agricultural development in Western Australia over the past 100 years has been the loss of most of the native vegetation and, consequently, massive reductions in the numbers of most of our native fauna. Thirteen mammal species are extinct and many bird and mammal species are extinct in some areas. These losses will increase as remnant native vegetation degrades under the impact of nutrients washed and blown from farmland, from the invasion by Western grey kangaroo grazing weeds and from grazing sheep. on pasture in the early morning. Even kangaroos are affected. -

CHARACTERISATION OF EXPERIMENTALLY INDUCED AND SPONTANEOUSLY OCCURRING DISEASE WITHIN CAPTIVE BRED DASYURIDS Scott Andrew Lindsay A thesis submitted in fulfillment of requirements for the postgraduate degree of Masters of Veterinary Science Faculty of Veterinary Science University of Sydney March 2014 STATEMENT OF ORIGINALITY Apart from assistance acknowledged, this thesis represents the unaided work of the author. The text of this thesis contains no material previously published or written unless due reference to this material is made. This work has neither been presented nor is currently being presented for any other degree. Scott Lindsay 30 March 2014. i SUMMARY Neosporosis is a disease of worldwide distribution resulting from infection by the obligate intracellular apicomplexan protozoan parasite Neospora caninum, which is a major cause of infectious bovine abortion and a significant economic burden to the cattle industry. Definitive hosts are canid and an extensive range of identified susceptible intermediate hosts now includes native Australian species. Pilot experiments demonstrated the high disease susceptibility and the unexpected observation of rapid and prolific cyst formation in the fat-tailed dunnart (Sminthopsis crassicaudata) following inoculation with N. caninum. These findings contrast those in the immunocompetent rodent models and have enormous implications for the role of the dunnart as an animal model to study the molecular host-parasite interactions contributing to cyst formation. An immunohistochemical investigation of the dunnart host cellular response to inoculation with N. caninum was undertaken to determine if a detectable alteration contributes to cyst formation, compared with the eutherian models. Selective cell labelling was observed using novel antibodies developed against Tasmanian devil proteins (CD4, CD8, IgG and IgM) as well as appropriate labelling with additional antibodies targeting T cells (CD3), B cells (CD79b, PAX5), granulocytes, and the monocyte-macrophage family (MAC387). -
Local Population Structure of a Naturally Occurring Metapopulation of the Quokka (Setonix Brachyurus Macropodidae: Marsupialia)

Seven previously known local populations and one unconfirmed site supporting the preferred, patchy and discrete, swampy habitat of the quokka were trapped. The quokka is now considered as locally extinct at three sites. The five remaining sites had extremely low numbers, ranging from 1 to 36 individuals. Population density at these sites ranged from 0.07 to 4.3 individuals per hectare. There has been no response to the on-going, 6 year fox control programme occurring in the region despite the quokkas’ high fecundity and this is due to low recruitment levels. The remaining quokka populations in the northern jarrah forest appear to be the terminal remnants of a collapsing metapopulation. # 2002 Elsevier Science Ltd. All rights reserved.

Macropod Herpesviruses Dec 2013
Herpesviruses and macropods Fact sheet Introductory statement Despite the widespread distribution of herpesviruses across a large range of macropod species there is a lack of detailed knowledge about these viruses and the effects they have on their hosts. While they have been associated with significant mortality events infections are usually benign, producing no or minimal clinical effects in their adapted hosts. With increasing emphasis being placed on captive breeding, reintroduction and translocation programs there is a greater likelihood that these viruses will be introduced into naïve macropod populations. The effects and implications of this type of viral movement are unclear. Aetiology Herpesviruses are enveloped DNA viruses that range in size from 120 to 250nm. The family Herpesviridae is divided into three subfamilies. Alphaherpesviruses have a moderately wide host range, rapid growth, lyse infected cells and have the capacity to establish latent infections primarily, but not exclusively, in nerve ganglia. Betaherpesviruses have a more restricted host range, a long replicative cycle, the capacity to cause infected cells to enlarge and the ability to form latent infections in secretory glands, lymphoreticular tissue, kidneys and other tissues. Gammaherpesviruses have a narrow host range, replicate in lymphoid cells, may induce neoplasia in infected cells and form latent infections in lymphoid tissue (Lachlan and Dubovi 2011, Roizman and Pellet 2001). There have been five herpesvirus species isolated from macropods, three alphaherpesviruses termed Macropodid Herpesvirus 1 (MaHV1), Macropodid Herpesvirus 2 (MaHV2), and Macropodid Herpesvirus 4 (MaHV4) and two gammaherpesviruses including Macropodid Herpesvirus 3 (MaHV3), and a currently unclassified novel gammaherpesvirus detected in swamp wallabies (Wallabia bicolor) (Callinan and Kefford 1981, Finnie et al. -

A Species-Level Phylogenetic Supertree of Marsupials
J. Zool., Lond.

P. Bininda-Emonds3, Elizabeth Boakes1,2 and Andy Purvis1 1 Department of Biological Sciences, Imperial College London, Silwood Park, Ascot SL5 7PY, U.K. 2 Institute of Zoology, Zoological Society of London, Regent’s Park, London NW1 4RY, U.K. 3 Lehrstuhl fur¨ Tierzucht, Technical University of Munich, Alte Akademie 12, 85354 Freising-Weihenstephan, Germany (Accepted 26 January 2004) Abstract Comparative studies require information on phylogenetic relationships, but complete species-level phylogenetic trees of large clades are difficult to produce. One solution is to combine algorithmically many small trees into a single, larger supertree. Here we present a virtually complete, species-level phylogeny of the marsupials (Mammalia: Metatheria), built by combining 158 phylogenetic estimates published since 1980, using matrix representation with parsimony. The supertree is well resolved overall (73.7%), although resolution varies across the tree, indicating variation both in the amount of phylogenetic information available for different taxa, and the degree of conflict among phylogenetic estimates. In particular, the supertree shows poor resolution within the American marsupial taxa, reflecting a relative lack of systematic effort compared to the Australasian taxa. There are also important differences in supertrees based on source phylogenies published before 1995 and those published more recently. The supertree can be viewed as a meta-analysis of marsupial phylogenetic studies, and should be useful as a framework for phylogenetically explicit comparative studies of marsupial evolution and ecology. -

Letendre et al. BMC Zoology (2018) 3:10 https://doi.org/10.1186/s40850-018-0036-3 BMC Zoology RESEARCHARTICLE Open Access Immunosenescence in a captive semelparous marsupial, the red-tailed phascogale (Phascogale calura) Corinne Letendre, Ethan Sawyer, Lauren J. Young and Julie M. Old* Abstract Background: The red-tailed phascogale is a ‘Near Threatened’ dasyurid marsupial. Males are semelparous and die off shortly after the breeding season in the wild due to a stress-related syndrome, which has many physiological and immunological repercussions. In captivity, males survive for more than 2 years but become infertile after their first breeding season. Meanwhile, females can breed for many years. This suggests that captive males develop similar endocrine changes as their wild counterparts and undergo accelerated aging. However, this remains to be confirmed. The health status and immune function of this species in captivity have also yet to be characterized. Results: Through an integrative approach combining post-mortem examinations, blood biochemical and hematological analyses, we investigated the physiological and health status of captive phascogales before, during, and after the breeding season. Adult males showed only mild lesions compatible with an endocrine disorder. Both sexes globally maintained a good body condition throughout their lives, most likely due to a high quality diet. However, biochemistry changes potentially compatible with an early onset of renal or hepatic insufficiency were detected in older individuals. Masses and possible hypocalcemia were observed anecdotally in old females. With this increased knowledge of the physiological status of captive phascogales, interpretation of their immune profile at different age stages was then attempted. -
Impact of Fox Baiting on Tiger Quoll Populations Project ID: 00016505
Impact of fox baiting on tiger quoll populations Project ID: 00016505 Final Report to Environment Australia and The New South Wales National Parks and Wildlife Service Gerhard Körtner and Shaan Gresser Copyright G. Körtner Executive Summary: The NSW Threat Abatement Plan for Predation by the Red Fox (TAP) identifies foxes as a major threat to the survival of many native mammals. The plan recommends baiting with compound 1080 (sodium monofluoroacetate) because it appears to be the most effective fox control measure. However, the plan also recognises the risk for tiger quolls as a non-target species. Although the actual impact of 1080 fox baiting on tiger quoll populations has not been assessed, this assumed risk has resulted in restrictions on the use of 1080 which render fox baiting programs labour intensive and expensive and which may compromise the effectiveness of the fox control. The aim of this project is to determine whether these precautions are necessary by measuring tiger quoll mortality during fox baiting programs using 1080. The project has been identified as a priority action (Obj. 2, action 5) of the TAP. Three experiments were conducted in north-east NSW between June 2000 and December 2001. Overall 78 quolls were trapped and 56 of those were fitted with mortality radio-transmitters. Baiting procedure followed Best Practice Guidelines (TAP) except that there was no free-feeding and baits were only surface buried. These modifications aimed to increase the exposure of quolls to bait. 1080 baits (3 mg / bait; Foxoff®) incorporating the bait marker Rhodamine B were deployed for 10 days along existing trails. -
Wildlife Parasitology in Australia: Past, Present and Future
CSIRO PUBLISHING Australian Journal of Zoology, 2018, 66, 286–305 Review https://doi.org/10.1071/ZO19017 Wildlife parasitology in Australia: past, present and future David M. Spratt A,C and Ian Beveridge B AAustralian National Wildlife Collection, National Research Collections Australia, CSIRO, GPO Box 1700, Canberra, ACT 2601, Australia. BVeterinary Clinical Centre, Faculty of Veterinary and Agricultural Sciences, University of Melbourne, Werribee, Vic. 3030, Australia. CCorresponding author. Email: [email protected] Abstract. Wildlife parasitology is a highly diverse area of research encompassing many fields including taxonomy, ecology, pathology and epidemiology, and with participants from extremely disparate scientific fields. In addition, the organisms studied are highly dissimilar, ranging from platyhelminths, nematodes and acanthocephalans to insects, arachnids, crustaceans and protists. This review of the parasites of wildlife in Australia highlights the advances made to date, focussing on the work, interests and major findings of researchers over the years and identifies current significant gaps that exist in our understanding. The review is divided into three sections covering protist, helminth and arthropod parasites. The challenge to document the diversity of parasites in Australia continues at a traditional level but the advent of molecular methods has heightened the significance of this issue. Modern methods are providing an avenue for major advances in documenting and restructuring the phylogeny of protistan parasites in particular, while facilitating the recognition of species complexes in helminth taxa previously defined by traditional morphological methods. The life cycles, ecology and general biology of most parasites of wildlife in Australia are extremely poorly understood. While the phylogenetic origins of the Australian vertebrate fauna are complex, so too are the likely origins of their parasites, which do not necessarily mirror those of their hosts. -

Intot Obliv i The disappearing native mammals of northern Australia Compiled by James Fitzsimons Sarah Legge Barry Traill John Woinarski Into Oblivion? The disappearing native mammals of northern Australia 1 SUMMARY Since European settlement, the deepest loss of Australian biodiversity has been the spate of extinctions of endemic mammals. Historically, these losses occurred mostly in inland and in temperate parts of the country, and largely between 1890 and 1950. A new wave of extinctions is now threatening Australian mammals, this time in northern Australia. Many mammal species are in sharp decline across the north, even in extensive natural areas managed primarily for conservation. The main evidence of this decline comes consistently from two contrasting sources: robust scientifi c monitoring programs and more broad-scale Indigenous knowledge. The main drivers of the mammal decline in northern Australia include inappropriate fi re regimes (too much fi re) and predation by feral cats. Cane Toads are also implicated, particularly to the recent catastrophic decline of the Northern Quoll. Furthermore, some impacts are due to vegetation changes associated with the pastoral industry. Disease could also be a factor, but to date there is little evidence for or against it. Based on current trends, many native mammals will become extinct in northern Australia in the next 10-20 years, and even the largest and most iconic national parks in northern Australia will lose native mammal species. This problem needs to be solved. The fi rst step towards a solution is to recognise the problem, and this publication seeks to alert the Australian community and decision makers to this urgent issue.
