  • The Western Ringtail Possum (Pseudocheirus Occidentalis)

    The Western Ringtail Possum (Pseudocheirus Occidentalis)

    A major road and an artificial waterway are barriers to the rapidly declining western ringtail possum, Pseudocheirus occidentalis Kaori Yokochi BSc. (Hons.) This thesis is presented for the degree of Doctor of Philosophy of The University of Western Australia School of Animal Biology Faculty of Science October 2015 Abstract Roads are known to pose negative impacts on wildlife by causing direct mortality, habitat destruction and habitat fragmentation. Other kinds of artificial linear structures, such as railways, powerline corridors and artificial waterways, have the potential to cause similar negative impacts. However, their impacts have been rarely studied, especially on arboreal species even though these animals are thought to be highly vulnerable to the effects of habitat fragmentation due to their fidelity to canopies. In this thesis, I studied the effects of a major road and an artificial waterway on movements and genetics of an endangered arboreal species, the western ringtail possum (Pseudocheirus occidentalis). Despite their endangered status and recent dramatic decline, not a lot is known about this species mainly because of the difficulties in capturing them. Using a specially designed dart gun, I captured and radio tracked possums over three consecutive years to study their movement and survival along Caves Road and an artificial waterway near Busselton, Western Australia. I studied the home ranges, dispersal pattern, genetic diversity and survival, and performed population viability analyses on a population with one of the highest known densities of P. occidentalis. I also carried out simulations to investigate the consequences of removing the main causes of mortality in radio collared adults, fox predation and road mortality, in order to identify effective management options.

    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.

  • Queensland, 2018

    Trip report – Queensland, Australia, July 1-21, 2018. I visited Queensland, Australia on a family trip in July. The trip was more family vacation than hard-core mammal watching, and I realize that Queensland is well covered on mammalwatching.com., but I thought I would post a trip report anyway to update some of the information already available. I travelled with my partner, Tracey, and my two children. Josie turned 18 in Australia and Ben is 14. We arrived in Brisbane around noon on July 1. We met up with my niece, Emma, and her partner, Brad, for dinner. The only mammals seen were Homo sapiens, but particularly pleasant and affable specimens. The next day we enjoyed some of Brisbane’s urban delights. That evening we drove to the Greater Glider Conservation Area near Alexandra Hills in Redlands in suburban Brisbane. It’s a fairly small park in suburbia but surprisingly dense with mammals. We saw Greater Glider, Squirrel Glider, about five Common Brushtail Possums and at least six Common Ringtail Possums. Several wallabies were seen which appeared to be Red-necked Wallabies. We then drove out to William Gibbs park. This is an even smaller park next to a school. However we quickly found two Koalas, two Common Ringtail possums and two Grey-headed Flying Foxes. Perhaps they were preparing to enter Noah’s Ark. Anyway, after about four hours we were so tired and jetlagged that we called it a night. Greater Glider The next day we drove to Binna Burra in Lammington National Park, less than two hours from Brisbane.

Box 1, Kensington, New South Wales 2033, AustraUa QJ INTRODUCTION Several species of Australian possums and gliders are often kept in zoos, wildlife parks and research establishments. All are nocturnal and arboreal with a wide range of dietary preferences. For the purposes of this chapter, these marsupials can be divided into the following groups; the most commonly kept species is given as an example: (1) Phalangers, e.g., the Common Brushtail Possum Trichosurus vulpecula; (2) Ringtail possums, e.g., the Common Ringtail Possum Pseudocheirus peregrinus; (3) Striped Possums and gliders including Leadbeater's Possum, e.g., the Sugar Glider Petaurus breviceps, (4) Pygmy-possums and the Feathertail Glider, e.g., the Eastern Pygmy-possum Cercartetus nanus; (5) The Honey Possum Tarsipes rostratus. For a review of the biology of Australian possum families, see the various chapters in Walton and Richardson (1989). Phalangers There are six species in this group ranging in adult size from 1-5 kg. The Common Brushtail Possum Trichosunis vulpecula is the only species of this group often kept in captivity. The Bobuck or Mountain Brushtail T. caninus and the Northem Brushtail Possum T. arnhemensis are locally common in the wild but only a few seem to find their way into captivity. The other three species, the Scaly-tailed Possum Wyulda squamicaudata, Spotted Cuscus Phalanger maculatus and the Grey Cuscus Phalanger orientalis are rare in Australia.

MORPHOLOGY AND PHYSIOLOGY OF THE METATHERIA 2 17. MORPHOLOGY AND PHYSIOLOGY OF THE METATHERIA EXTERNAL CHARACTERISTICS The Metatheria, comprising a single order, Marsupialia, is a large and diverse group of animals and exhibits a considerable range of variation in external features. The variation found is intimately related to the animals' habits and, in most instances, parallels that are found in the Eutheria. Useful general references to external characteristics include Pocock (1921), Jones (1923a, 1924), Grassé (1955), Frith & Calaby (1969), Ride (1970) and Strahan (1983). Body form In size, the marsupials range upwards from the Long-tailed Planigale, Planigale ingrami, a small, mouse-like animal weighing only around 4.2 g, with a head- body length of 59 mm and a tail 55 mm long. At the other extreme, there are large kangaroos, such as the Red Kangaroo, Macropus rufus, in which the males may weigh as much as 85 kg and attain a head-body length of 1400 mm and a tail of 1000 mm. Body shape also varies greatly. The primarily carnivorous marsupials, the dasyurids (for example, antechinuses, dunnarts, quolls, planigales and others), are small to medium sized quadrupeds with subequal limbs. The tail is relatively slender and generally about half the length of the body. The omnivorous peramelids show increased development of the hind limbs in keeping with their rapid bounding locomotion. Saltatory or hopping forms (for example kangaroos and wallabies), carry the hind limb specialisation to an extreme, with a concomitant reduction of the forelimbs (Fig.

Conservation Medicine Program, College of Veterinary Medicine, Murdoch University 2. Northern Territory Department of Land Resource Management 2 This page has been left intentionally blank National Environmental Research Program - Small Mammal Disease Investigation: Final Report June 2015 3 EXECUTIVE SUMMARY There is compelling evidence of broad-scale declines in populations of small terrestrial native mammals in northern Australia, including the Top End of the Northern Territory (NT) over the past 20 years. Causes under consideration include changed fire regimes, introduced fauna (including predators) and disease. To date information on health and disease in northern Australian mammals has been limited. Disease is increasingly recognised as a primary driver of some wildlife population declines and extinctions e.g., Tasmanian devil facial tumour disease, white nose syndrome in bats and chytrid fungus in amphibians. Disease has been identified as a risk factor for extinction in declining and fragmented wildlife populations globally, particularly in situations of increased environmental stressors, changing ecosystems, arrival of new vertebrate threats or climate change. Unless wild populations are studied in detail over long periods of time, the effects of disease are easily overlooked and may be difficult to determine. This study is the largest and most comprehensive study of health and disease in small mammals in northern Australia and is one of a small number of studies worldwide to have approached investigation of wildlife populations in this comprehensive manner.

    Original Distribution of Trichosurus Vulpecula (Marsupialia: Phalangeridae) in Western Australia, with Particular Reference to Occurrence Outside the Southwest

    Journal of the Royal Society of Western Australia, 95: 83–93, 2012 Original distribution of Trichosurus vulpecula (Marsupialia: Phalangeridae) in Western Australia, with particular reference to occurrence outside the southwest I ABBOTT Department of Environment and Conservation, Locked Bag 104, Bentley Delivery Centre, WA 6983, Australia. ! [email protected] Trichosurus vulpecula, ‘common brushtail possum’, is currently considered to have never occurred in ~20% of Western Australia. This paper reports the results of a survey of historical sources, showing that the species was widely known to Aborigines and was once more broadly distributed, and may have occurred across almost all of Western Australia in 1829, the year of first settlement by Europeans. A remarkable contraction in geographical range commenced ca 1880, caused by an epizootic, and continued from ca 1920–1960 as a result of depredation by foxes (Vulpes vulpes). Some 220 Aboriginal names from outside the southwest were discovered. These are tabulated, and most can be reduced to seven regional names. Several or all of these names appear suitable for adoption into regional use in Western Australia. The current vernacular name is now inaccurate (the species is no longer common anywhere in Western Australia and is not closely related to the Virginia opossum, Didelphys virginiana, which belongs to a different family of marsupials), and should be replaced by one or more Aboriginal names.

    Ensuring the Long-Term Survival of the Endangered Western Ringtail Possum (Pseudocheirus Occidentalis) in the Shire of Augusta

    1 Ensuring the long-term survival of the Endangered Western ringtail possum (Pseudocheirus occidentalis) in the Shire of Augusta-Margaret River: The impact of recent fires and the threat of future fires Background The Shire of Augusta-Margaret River established a Biodiversity Working Party within its Sustainability Advisory Committee (SAC) in 2008 and accepted its first recommendations that: 1. The Shire initiate an upgrade survey of peppermint woodlands likely to provide suitable habitat for Western Ringtail possums 2. The Shire seek external funding to engage a biological consultant to survey remnant Western Ringtail populations. The survey should also enlist the help of ratepayers through the distribution of a questionnaire to collect evidence of sightings, road-kills, dreys (nests) and scats (droppings). 3. The Shire initiate a signage policy designed to increase the public’s awareness of an endangered marsupial species in its midst1. Although two applications have been made to the State Government for funding via its Community Grants Scheme, neither was successful. In 2015 $10k remaining in the Environment Management Fund were reallocated for a public 1 Shire of Augusta–Margaret River Biodiversity Conservation Strategy, Discussion paper Prepared by the Shire of Augusta-Margaret River, 23 May 2005 2 awareness programme involving signage, brochures and other means of alerting ratepayers to the plight of ringtail possums. Biology of Western Ringtail Possums The Western ringtail possum, (Pseudocheirus occidentalus) is now listed as “Endangered” under the Federal EPBC Act, a change from its former listing as “Vulnerable” in the 2000 IUCN Red List of Threatened Species and “Threatened” under the Western Australian Wildlife Conservation Act2.
