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. -
On Christmas Island. the Presence of Trypanosoma in Cats and Rats (From All Three Locations) and Leishmania
Invasive animals and the Island Syndrome: parasites of feral cats and black rats from Western Australia and its offshore islands Narelle Dybing BSc Conservation Biology, BSc Biomedical Science (Hons) A thesis submitted to Murdoch University to fulfil the requirements for the degree of Doctor of Philosophy in the discipline of Biomedical Science 2017 Author’s Declaration I declare that this thesis is my own account of my research and contains as its main content work that has not previously been submitted for a degree at any tertiary education institution. Narelle Dybing i Statement of Contribution The five experimental chapters in this thesis have been submitted and/or published as peer reviewed publications with multiple co-authors. Narelle Dybing was the first and corresponding author of these publications, and substantially involved in conceiving ideas and project design, sample collection and laboratory work, data analysis, and preparation and submission of manuscripts. All publication co-authors have consented to their work being included in this thesis and have accepted this statement of contribution. ii Abstract Introduced animals impact ecosystems due to predation, competition and disease transmission. The effect of introduced infectious disease on wildlife populations is particularly pronounced on islands where parasite populations are characterised by increased intensity, infra-community richness and prevalence (the “Island Syndrome”). This thesis studied parasite and bacterial pathogens of conservation and zoonotic importance in feral cats from two islands (Christmas Island, Dirk Hartog Island) and one mainland location (southwest Western Australia), and in black rats from Christmas Island. The general hypothesis tested was that Island Syndrome increases the risk of transmission of parasitic and bacterial diseases introduced/harboured by cats and rats to wildlife and human communities. -

By Abigail Misfeldt A THESIS Presented to the Faculty of The University of Nebraska-Lincoln In Partial Fulfillment of Requirements For the Degree of Bachelor of Science Major: Environmental Studies Under the Supervision of Dr. David Gosselin Lincoln, Nebraska November 2020 Abstract Red foxes are one of the few creatures able to adapt to living alongside humans as we have evolved. All humans and wildlife have some id of relationship, be it a friendly one or one of mutual hatred, or simply a neutral one. Through a systematic research review of legends, books, and journal articles, I mapped how humans and foxes have evolved together. -
Ba3444 MAMMAL BOOKLET FINAL.Indd
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. -

The IUCN Red List of Threatened Speciestm
Species 2014 Annual ReportSpecies the Species of 2014 Survival Commission and the Global Species Programme Species ISSUE 56 2014 Annual Report of the Species Survival Commission and the Global Species Programme • 2014 Spotlight on High-level Interventions IUCN SSC • IUCN Red List at 50 • Specialist Group Reports Ethiopian Wolf (Canis simensis), Endangered. © Martin Harvey Muhammad Yazid Muhammad © Amazing Species: Bleeding Toad The Bleeding Toad, Leptophryne cruentata, is listed as Critically Endangered on The IUCN Red List of Threatened SpeciesTM. It is endemic to West Java, Indonesia, specifically around Mount Gede, Mount Pangaro and south of Sukabumi. The Bleeding Toad’s scientific name, cruentata, is from the Latin word meaning “bleeding” because of the frog’s overall reddish-purple appearance and blood-red and yellow marbling on its back. Geographical range The population declined drastically after the eruption of Mount Galunggung in 1987. It is Knowledge believed that other declining factors may be habitat alteration, loss, and fragmentation. Experts Although the lethal chytrid fungus, responsible for devastating declines (and possible Get Involved extinctions) in amphibian populations globally, has not been recorded in this area, the sudden decline in a creekside population is reminiscent of declines in similar amphibian species due to the presence of this pathogen. Only one individual Bleeding Toad was sighted from 1990 to 2003. Part of the range of Bleeding Toad is located in Gunung Gede Pangrango National Park. Future conservation actions should include population surveys and possible captive breeding plans. The production of the IUCN Red List of Threatened Species™ is made possible through the IUCN Red List Partnership.
