This thesis began as an investigation into evolution of the platypus family (Ornithorhynchidae, Monotremata), now known from both Australia and South America. The thesis broadened its scope with inclusion of non-ornithorhynchid Mesozoic monotremes from Lightning Ridge, NSW. This change in direction brought an unexpected result: a fossil mammal from Lightning Ridge investigated for this thesis (presumed to be monotreme: Flannery et al., 1995) appears to be a new and unique type of mammal.

Australian mammals have fared badly over the past 200 years with 17 species extinct, 10 species surviving only on islands, and another 17 reduced to remnant populations of less than 10% of their range at the time of European settlement. Most extinct or threatened species fall within a critical weight range of 35 g to 5,500 g (CWR), as defined by Burbidge and McKenzie (1989). A disproportionate number come from arid and semi-arid Australia. This thesis poses the questions: Why have these species proved so vulnerable and what can be done to redress the situation?

Dryland Australia has a distinctive mammal fauna that has been severely impacted by novel threats since European colonisation. I aimed to understand the defining characteristics of mammal refuges in this region. In chapter 2 I used atlas data to compare the historic and contemporary distributions of dryland marsupials. The greater bilby and common brushtail possum have substantially contracted in distribution. The bilby was more likely to occur on land without cattle grazing and with low rabbit densities, while the possum has contracted to cooler areas. In chapter 3 I focused on the MacDonnell

Morphological data are crucial in evolutionary analyses for merging fossils into the tree of life, calibrating dating analyses and for enhancing inference of biological patterns and processes. Morphological phylogenetics is dominated by homoplastic characters, functional and developmental correlations, and also by highly subjective definitions of characters and their states, which in turn can mislead phylogeny reconstruction. A first study assessed the implications of biases among characters in Mesozoic mammals. Then, geometric morphometrics and molecular data were combined to study the system

Predation by exotic predators (cats Felis catus and foxes Vulpes vulpes) is believed to be one of the factors that has contributed to the decline of medium-sized mammals in arid Australia. Other factors include habitat degradation by introduced herbivores (rabbits Oryctolagus cuniculus and grazing stock) and altered fire regimes after Aboriginal people moved into permanent settlements. In general, the impact of exotic predators on arid zone mammals is believed to be significant only when predator numbers have been elevated by increased food availability from exotic prey species (rabbits, house

I analysed the diet of adult male, adult female and juvenile NZ fur seals and adult male Australian fur seals and studied the diving behaviour of adult male and lactating female NZ fur

Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each a

Streszczenie:

Snow is an important factor in the lives of flora and fauna in those regions where it occurs. Despite this, there is a relative lack of information about the ecological role of snow. In addition, on a global scale the majority of the research on snow ecology has been based in the boreal regions of North America and Eurasia. Insights from these areas may not extrapolate well to Australia. The distribution and physical characteristics of snow are highly variable both temporally and spatially. Its occurrence is affected by a range of factors acting at multiple scales. Working in snow covered ar

Reports of interactions between marine mammals and fisheries are on the increase globally. This is mainly because fishery effort has increased to feed the burgeoning human population and because advances in technology have allowed fisheries to exploit habitats that were until recently inaccessible. Additionally, many marine mammal populations decimated by harvesting over the past few hundred years are recovering and the growing conservation community is paying unprecedented attention to their welfare and conservation generally, with growing interest in their interactions with fisheries.

The earth is currently believed to be in the midst of a mass-extinction episode. Globally, approximately a quarter of mammal species are at risk of extinction. To prevent further degradation of mammals, it is important to understand what causes species to decline, and why some species seem to be more vulnerable than others. Comparative studies in vertebrate taxa often find that a small geographic range size is a strong predictor of high extinction risk. I found that current range size in Australian mainland mammals is a response to previous threatening processes. Using current range size as a

The Australian arid zone has the highest recent mammal extinction rate in the world with most species in the critical weight range of 35 g to 5.5 kg now regionally or globally extinct. Reversing arid zone mammal decline has become a major focus for conservation organizations and reintroduction programs are a common tool in species recovery. Unfortunately, reintroduction success in Australia is low and predation from introduced cats and foxes is commonly cited as the cause of reintroduction failure. In this thesis, I aimed to improve reintroduction success in the arid zone by exploring predatio

Marsupials have complex and interesting socioecology and life history strategies that differ quite markedly to much - studied eutherian mammals. However, the socioecology and life history strategies of a number of Australian marsupials are most often observed only within the context of a much larger study on their ecology. My aim was to study, using a combination of behavioural observations and molecular DNA techniques, aspects of the socioecology of a population of yellow - bellied gliders ( Petaurus australis ) in Rennick State Forest, south - western Victoria.

This thesis documents the history of Quaternary mammalian faunas from the northern Monaro region of the southern highlands of Eastern Australia. The area currently has a cold semi-arid climate and, together with a series of fossil localities of different ages, provides an opportunity to examine the relationships between faunal changes and palaeoenvironments in this part of Australia during the Quaternary. Fossil material from seven localities within the northern Monaro region is described together with the geology of the sites in which they occur. The localities are Pilot Creek, Bunyan

In Port Phillip Bay, Victoria, Australia, the endemic and vulnerable Burrunan dolphin (Tursiops australis) is the target species of a non-consumptive, economically important, dolphin-swim industry. This industry commenced in 1986, and southern Port Phillip Bay is now a key eco-tourism destination in Victoria, with 8 permitted trips daily targeting swimming with Burrunan dolphins. Although this industry has been in operation for 29 years, understanding of the occurrence, demographics, habitat use, behaviour and effects of tourism on Burrunan dolphins is limited.

Otariid seals pose several challenges in collecting behavioural data due because of the geographical decoupling of breeding habitat (terrestrial) and foraging grounds (aquatic). Additionally, life history traits such as breeding chronology and moult state constrain the temporal window over which data can be collected. Expensive telemetry devices coupled with logistical difficulties and the biology of animals often limits the ability to answer questions concerning the role of seasonal or life-history differences in foraging ecology.

Australia has one of the world's worst rates of mammal extinctions, accounting for about one third of the mammal species that have become extinct in the world since 1600 (Burbidge and Manly 2002). Most of these documented declines and extinctions have been concentrated towards mammals in the arid-zone of central Australia. In South Australia (SA), one of the arid-zone species that has undergone substantial declines in range and abundance is the black-footed rock-wallaby, Petrogale lateralis (MacDonnell Ranges race). Animals are now restricted to the Anangu Pitjantjatjara Yankunytjatjara (APY)
