Mammals in the Museum Discovery Activity Sheet Y7-10 What is a mammal? Mammals are warm-blooded animals that have hair of some form on their bodies and mammary glands which produce milk. Different species of mammals have adapted to live in many different environments- on the land, underground, in the air, in the tree tops and underwater. Mammals are divided into three groups – monotremes, marsupials and placentals. Monotremes lay eggs. Marsupials give birth to very small, poorly developed offspring. Most female marsupials have pouches and the young develop inside the pouch. Placental mammals, like humans, give birth to well-developed young. Monotremes, marsupials and placentals Do a little research to further investigate the differences between the three types of mammals. For example, how does a monotreme provide milk to its young? Do all marsupials have pouches? Sort the mammals! Sort this list of mammals into monotremes, marsupials and placentals.

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).

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.

Tracking collars were fitted to 67 of the kangaroos to monitor survival rates and movement patterns over 12 months. Spotlighting and camera traps were used as a secondary monitoring technique particularly for those kangaroos without collars. The survival rate of kangaroos was poor, with an estimated 80% dying within the first month following relocation and only six collared kangaroos surviving for up to 12 months. This result implicates stress associated with the capture, handling, and transport of animals as the likely cause. The unexpected rapid rate of mortality emphasises the importance of minimising stress when undertaking animal relocations. Abstract: The expansion of urban areas and associated clearing of habitat can have severe consequences for native wildlife. One option for managing wildlife in these situations is to relocate them.

The Hunter and Biodiversity in Tasmania
The Hunter and Biodiversity in Tasmania The Hunter takes place on Tasmania’s Central Plateau, where “One hundred and sixty-five million years ago potent forces had exploded, clashed, pushed the plateau hundreds of metres into the sky.” [a, 14] The story is about the hunt for the last Tasmanian tiger, described in the novel as: “that monster whose fabulous jaw gapes 120 degrees, the carnivorous marsupial which had so confused the early explorers — a ‘striped wolf’, ‘marsupial wolf.’” [a, 16] Fig 1. Paperbark woodlands and button grass plains near Derwent Bridge, Central Tasmania. Source: J. Stadler, 2010. Biodiversity “Biodiversity”, or biological diversity, refers to variety in all forms of life—all plants and animals, their genes, and the ecosystems they live in. [b] It is important because all living things are connected with each other. For example, humans depend on living things in the environment for clean air to breathe, food to eat, and clean water to drink. Biodiversity is one of the underlying themes in The Hunter, a Tasmanian film directed by David Nettheim in 2011 and based on Julia Leigh’s 1999 novel about the hunt for the last Tasmanian Tiger. The film and the novel showcase problems that arise from loss of species, loss of habitat, and contested ideas about land use. The story is set in the Central Plateau Conservation Area and much of the film is shot just south of that area near Derwent Bridge and in the Florentine Valley. In Tasmania, land clearing is widely considered to be the biggest threat to biodiversity [c, d].

Biparental Care and Obligate Monogamy in the Rock-Haunting Possum, Petropseudes Dahli, from Tropical Australia
ANIMAL BEHAVIOUR, 2000, 59, 1001–1008 doi:10.1006/anbe.1999.1392, available online at http://www.idealibrary.com on Biparental care and obligate monogamy in the rock-haunting possum, Petropseudes dahli, from tropical Australia MYFANWY J. RUNCIE CRC for Sustainable Development of Tropical Savannas, Northern Territory University (Received 10 May 1999; initial acceptance 9 June 1999; final acceptance 30 December 1999; MS. number: 6222R) Monogamy is rare among mammals, including marsupials. I studied the social organization of the little-known rock-haunting possum in Kakadu National Park in Northern Australia. Preliminary field observations revealed that the majority of possums live in cohesive groups consisting of a female–male pair and young, suggesting a monogamous mating system. I used radiotracking to determine home range patterns, and observations to measure the degree of symmetry between the sexes in maintaining the pair bond and initiating changes in group activity. I also measured the extent of maternal and paternal indirect and direct care. Nocturnal observations and radiotelemetric data from 3 years showed that six possum groups maintained nonoverlapping home ranges with long-term consorts and young sharing dens. Males contributed more than females to maintaining the pair bond but they contributed equally to parental care. For the first time, the parental behaviours of bridge formation, embracing, marshalling of young, sentinel behaviour and tail beating are reported in a marsupial. Males participated to a high degree in maintaining relationships with one mate and their offspring. Collectively, these results suggest that the mating system of this wild population of rock-haunting possums is obligate social monogamy.

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.

Cases that both support and contradict these predictions have been observed in empirical and modelling investigations that continue to under-represent small mammal species (Introduction). Given small mammals are primary or higher order consumers and often dispersal limited, incorporating resource gradients that define the fundamental niche may be vital for generating accurate estimates of range shift. This idea was investigated through the influence of coarse to fine resolution, landscape- and quadrat-scale data on the range dynamics of four temperate- and five arid-zone small mammals.
