The mite burrows into the skin of its host individual wombats. If left untreated, mange can result in the causing thick, crusty skin, and hair loss. Mange can affect lots of death of affected individuals. mammal species but the common wombat is one of the most Severe outbreaks of mange can result in a significant affected species.

  • A Phylogeny and Timescale for Marsupial Evolution Based on Sequences for Five Nuclear Genes
    J Mammal Evol DOI 10.1007/s10914-007-9062-6 ORIGINAL PAPER A Phylogeny and Timescale for Marsupial Evolution Based on Sequences for Five Nuclear Genes Robert W. Meredith & Michael Westerman & Judd A. Case & Mark S. Springer # Springer Science + Business Media, LLC 2007 Abstract Even though marsupials are taxonomically less diverse than placentals, they exhibit comparable morphological and ecological diversity. However, much of their fossil record is thought to be missing, particularly for the Australasian groups. The more than 330 living species of marsupials are grouped into three American (Didelphimorphia, Microbiotheria, and Paucituberculata) and four Australasian (Dasyuromorphia, Diprotodontia, Notoryctemorphia, and Peramelemorphia) orders. Interordinal relationships have been investigated using a wide range of methods that have often yielded contradictory results. Much of the controversy has focused on the placement of Dromiciops gliroides (Microbiotheria). Studies either support a sister-taxon relationship to a monophyletic Australasian clade or a nested position within the Australasian radiation. Familial relationships within the Diprotodontia have also proved difficult to resolve. Here, we examine higher-level marsupial relationships using a nuclear multigene molecular data set representing all living orders. Protein-coding portions of ApoB, BRCA1, IRBP, Rag1, and vWF were analyzed using maximum parsimony, maximum likelihood, and Bayesian methods. Two different Bayesian relaxed molecular clock methods were employed to construct a timescale for marsupial evolution and estimate the unrepresented basal branch length (UBBL). Maximum likelihood and Bayesian results suggest that the root of the marsupial tree is between Didelphimorphia and all other marsupials. All methods provide strong support for the monophyly of Australidelphia. Within Australidelphia, Dromiciops is the sister-taxon to a monophyletic Australasian clade.

  • Thylacinidae
    FAUNA of AUSTRALIA 20. THYLACINIDAE JOAN M. DIXON 1 Thylacine–Thylacinus cynocephalus [F. Knight/ANPWS] 20. THYLACINIDAE DEFINITION AND GENERAL DESCRIPTION The single member of the family Thylacinidae, Thylacinus cynocephalus, known as the Thylacine, Tasmanian Tiger or Wolf, is a large carnivorous marsupial (Fig. 20.1). Generally sandy yellow in colour, it has 15 to 20 distinct transverse dark stripes across the back from shoulders to tail. While the large head is reminiscent of the dog and wolf, the tail is long and characteristically stiff and the legs are relatively short. Body hair is dense, short and soft, up to 15 mm in length. Body proportions are similar to those of the Tasmanian Devil, Sarcophilus harrisii, the Eastern Quoll, Dasyurus viverrinus and the Tiger Quoll, Dasyurus maculatus. The Thylacine is digitigrade. There are five digital pads on the forefoot and four on the hind foot. Figure 20.1 Thylacine, side view of the whole animal. (© ABRS)[D. Kirshner] The face is fox-like in young animals, wolf- or dog-like in adults. Hairs on the cheeks, above the eyes and base of the ears are whitish-brown. Facial vibrissae are relatively shorter, finer and fewer than in Tasmanian Devils and Quolls. The short ears are about 80 mm long, erect, rounded and covered with short fur. Sexual dimorphism occurs, adult males being larger on average. Jaws are long and powerful and the teeth number 46. In the vertebral column there are only two sacrals instead of the usual three and from 23 to 25 caudal vertebrae rather than 20 to 21.

    REPRODUCTIONREVIEW Wombat reproduction (Marsupialia; Vombatidae): an update and future directions for the development of artificial breeding technology Lindsay A Hogan1, Tina Janssen2 and Stephen D Johnston1,2 1Wildlife Biology Unit, Faculty of Science, School of Agricultural and Food Sciences, The University of Queensland, Gatton 4343, Queensland, Australia and 2Australian Animals Care and Education, Mt Larcom 4695, Queensland, Australia Correspondence should be addressed to L A Hogan; Email: [email protected] Abstract This review provides an update on what is currently known about wombat reproductive biology and reports on attempts made to manipulate and/or enhance wombat reproduction as part of the development of artificial reproductive technology (ART) in this taxon. Over the last decade, the logistical difficulties associated with monitoring a nocturnal and semi-fossorial species have largely been overcome, enabling new features of wombat physiology and behaviour to be elucidated. Despite this progress, captive propagation rates are still poor and there are areas of wombat reproductive biology that still require attention, e.g. further characterisation of the oestrous cycle and oestrus. Numerous advances in the use of ART have also been recently developed in the Vombatidae but despite this research, practical methods of manipulating wombat reproduction for the purposes of obtaining research material or for artificial breeding are not yet available. Improvement of the propagation, genetic diversity and management of wombat populations requires a thorough understanding of Vombatidae reproduction. While semen collection and cryopreservation in wombats is fairly straightforward there is currently an inability to detect, induce or synchronise oestrus/ovulation and this is an impeding progress in the development of artificial insemination in this taxon.

    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.

  • Exotic to Australia
    Fact sheet Introductory statement Foot and mouth disease (FMD) is a highly contagious viral vesicular disease of cloven hoofed animals. It is a major issue in international trade in livestock and livestock products. Australia is free of the disease and it is vital that it remains so. The 2001 outbreak in the United Kingdom resulted in over 10 million cattle and sheep being slaughtered at a cost of over GBP 8 billion in order to eradicate the disease. This fact sheet summarises what is known about FMD and Australian native wildlife. WHA also manages an fact sheet that briefly summarises information on FMD and feral animals “Foot and Mouth Disease (General Information)”. Aetiology and natural hosts FMD is caused by an aphthovirus belonging to the family Picornaviridae. It is a single stranded non enveloped 25 nm RNA virus. There are seven serotypes: A, O, C, SAT 1, SAT 2, SAT 3, and Asia 1. All cloven hoofed animals are considered susceptible. Cases have also been reported in elephants, hedgehogs and some rodents. World distribution and occurrences in Australia FMD is endemic in Africa, the Middle East, Asia and parts of South America. The disease has almost been eradicated from Europe with the most recent cases occurring in the United Kingdom and Cyprus in 2007. FMD has not occurred in Australia for over 130 years, and then only in livestock. Minor outbreaks occurred in 1801, 1804, 1871 and 1872 (Geering et al 1995). However, a case was reported in an eastern grey kangaroo (Macropus giganteus) held in a zoo in India (Bhattacharya et al 2003).

  • Cercartetus Lepidus (Diprotodontia: Burramyidae)
    MAMMALIAN SPECIES 842:1–8 Cercartetus lepidus (Diprotodontia: Burramyidae) JAMIE M. HARRIS School of Environmental Science and Management, Southern Cross University, Lismore, New South Wales, 2480, Australia; [email protected] Abstract: Cercartetus lepidus (Thomas, 1888) is a burramyid commonly called the little pygmy-possum. It is 1 of 4 species in the genus Cercartetus, which together with Burramys parvus form the marsupial family Burramyidae. This Lilliputian possum has a disjunct distribution, occurring on mainland Australia, Kangaroo Island, and in Tasmania. Mallee and heath communities are occupied in Victoria and South Australia, but in Tasmania it is found mainly in dry and wet sclerophyll forests. It is known from at least 18 fossil sites and the distribution of these reveal a significant contraction in geographic range since the late Pleistocene. Currently, this species is not listed as threatened in any state jurisdictions in Australia, but monitoring is required in order to more accurately define its conservation status. DOI: 10.1644/842.1.

  • A New Family of Diprotodontian Marsupials from the Latest Oligocene of Australia and the Evolution of Wombats, Koalas, and Their Relatives (Vombatiformes) Robin M
    www.nature.com/scientificreports OPEN A new family of diprotodontian marsupials from the latest Oligocene of Australia and the evolution of wombats, koalas, and their relatives (Vombatiformes) Robin M. D. Beck1,2 ✉ , Julien Louys3, Philippa Brewer4, Michael Archer2, Karen H. Black2 & Richard H. Tedford5,6 We describe the partial cranium and skeleton of a new diprotodontian marsupial from the late Oligocene (~26–25 Ma) Namba Formation of South Australia. This is one of the oldest Australian marsupial fossils known from an associated skeleton and it reveals previously unsuspected morphological diversity within Vombatiformes, the clade that includes wombats (Vombatidae), koalas (Phascolarctidae) and several extinct families. Several aspects of the skull and teeth of the new taxon, which we refer to a new family, are intermediate between members of the fossil family Wynyardiidae and wombats. Its postcranial skeleton exhibits features associated with scratch-digging, but it is unlikely to have been a true burrower. Body mass estimates based on postcranial dimensions range between 143 and 171 kg, suggesting that it was ~5 times larger than living wombats. Phylogenetic analysis based on 79 craniodental and 20 postcranial characters places the new taxon as sister to vombatids, with which it forms the superfamily Vombatoidea as defned here. It suggests that the highly derived vombatids evolved from wynyardiid-like ancestors, and that scratch-digging adaptations evolved in vombatoids prior to the appearance of the ever-growing (hypselodont) molars that are a characteristic feature of all post-Miocene vombatids. Ancestral state reconstructions on our preferred phylogeny suggest that bunolophodont molars are plesiomorphic for vombatiforms, with full lophodonty (characteristic of diprotodontoids) evolving from a selenodont morphology that was retained by phascolarctids and ilariids, and wynyardiids and vombatoids retaining an intermediate selenolophodont condition.
