Reconstructing the impact of climate change on Australian native species. This project will explore the impact of past climate change on Australian native animals to identify species and ecosystems at greatest potential risk, and to help predict and minimise the effects of future change.
Mesozoic Austral Biodiversity: Research and Regional Museum Applications. The impact of environmental alteration on Australia’s biodiversity has poorly understood long-term effects. This project examines the controversial biogeography and evolution of Australia’s biodiversity during the Age of Dinosaurs (mid-Cretaceous ~100 MYA) and their adaptational responses to climatic change. Fossils readily capture the public imagination and thus help promote complex scientific concepts in the global media ....Mesozoic Austral Biodiversity: Research and Regional Museum Applications. The impact of environmental alteration on Australia’s biodiversity has poorly understood long-term effects. This project examines the controversial biogeography and evolution of Australia’s biodiversity during the Age of Dinosaurs (mid-Cretaceous ~100 MYA) and their adaptational responses to climatic change. Fossils readily capture the public imagination and thus help promote complex scientific concepts in the global media. This project raises awareness about sustainable use of non-renewable fossil resources through public education and ecotourism fieldwork programs; these will help generate local interest and thus protection of sensitive fossil localities by highlighting them as lucrative tourism assets for regional communities.Read moreRead less
Were abrupt changes in the Precambrian global carbon cycle the trigger for animal appearance and radiation on Earth? The origin of complex life and the properties that allow that life to be sustained on this planet are recorded within the geologic record. This project will reveal the role that severe perturbations of the global carbon cycle and climate had in triggering the step-wise change to animal life after billions of years of only single cell organisms.
Going beyond genetics: the shape of marsupial evolution and conservation. This project aims to explain the past and protect the present biodiversity of endangered marsupial mammals such as bilbies and koalas. It will generate new knowledge using an interdisciplinary combination of 3D analysis of skull shape, reflecting a mammal’s ability to feed and sense its surrounds, with the fast-moving fields of marsupial conservation and evolutionary genetics. This will help to anticipate if, and how, chan ....Going beyond genetics: the shape of marsupial evolution and conservation. This project aims to explain the past and protect the present biodiversity of endangered marsupial mammals such as bilbies and koalas. It will generate new knowledge using an interdisciplinary combination of 3D analysis of skull shape, reflecting a mammal’s ability to feed and sense its surrounds, with the fast-moving fields of marsupial conservation and evolutionary genetics. This will help to anticipate if, and how, changing environments and declining numbers reduce these species’ ability to adapt. Benefits include better information to support improved conservation decisions and identification of genes underlying the evolution of marsupial skull diversity.Read moreRead less
Comparative Paleogenomics of the Arctic Tundra Ecosystem: the genetic response of plants and animals to climate change. This project will use DNA from deep-frozen seeds and bones 100,000 years old to record how species respond to climate change - by adapting and surviving or by shifting ranges and moving. Very large numbers of genes will be examined to identify changes across the genomes of four plant and two animal species, and contrast the responses to major climatic shifts.

Summary
Confocal microscope for high-resolution microtopographic analysis of surfaces in historical, forensic and polymer sciences. High-resolution analyses of microscopic patterns on surfaces using confocal microscopy can provide vital clues into the nature of ancient diets and environments, adaptive evolution, weapons used in crimes, and properties of polymers. This instrument will heighten Australia’s capacity for world-leading research in areas of major national importance.
Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selec ....Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selection and drift. It will create a novel temporal dataset of genomic adaptation and evolution, and will generate critical data for studies of evolutionary processes such as extinctions, speciation and conservation biology and management.Read moreRead less
The Eocene high latitude Australasian 'tropics' in a changing climate: resolving conflicting evidence. Between 45 to 30 million years ago, high latitude subtropical floras in Australia and New Zealand experienced significant climate change, leading to the evolution of present day vegetation. Understanding the effects of this climate change on extinction and speciation will produce more accurate predictions about modern floras when faced with climate change.
The genomics of adaptation to environmental change in an ecologically important non-model aquatic organism. Understanding whether natural populations will be able to adapt to rapid environmental change is a major research priority in the twenty-first-century. This project will answer fundamental questions about adaptation and will contribute towards the sustainable management of both aquatic biodiversity and water resources in Australia.
The physiology of biome shifts and macroevolutionary change: how did Australian skinks colonise the arid zone so successfully? This project will examine two of Australia's most diverse lizard lineages, Lerista and Ctenotus, and will identify the physiological and morphological traits that enabled them to adaptively radiate within the arid zone. It will highlight those traits likely to be adaptive for environments predicted to become widespread under climate change.
