Reconstructing the evolution of climatic tolerances in conifers. This project aims to trace the evolution of climate tolerance in conifers by combining evidence from fossils, phylogenies, physiology and mathematics. The project plans to use innovative methods to overcome the biases in methods currently used to trace evolutionary change.

This project aims to trace the evolution of climate tolerance in conifers by combining evidence from fossils, phylogenies, physiology and mathematics. The project plans to use innovative methods to overcome the biases in methods currently used to trace evolutionary change. The project plans to integrate data from three sources: the global fossil record, new models of current climatic tolerances of conifers, and mathematical simulations of how and when methods of reconstructing ancestral ecology fail. The combined results should show how this important group of organisms has responded to past climate change and how they will respond in the future. It should also provide improved estimates of past terrestrial climates.Read moreRead less

Summary
Integrating ecology and evolution: how does sexual selection affect population fitness and extinction? Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationsh ....Integrating ecology and evolution: how does sexual selection affect population fitness and extinction? Improving our understanding of population fitness could produce important new advances in evolutionary and conservation biology. Sexual selection has been proposed to both help and harm population fitness, but unfortunately these opposing effects have been studied in isolation. This project will develop new theory to resolve confusion over the definition of population fitness and its relationship with sexual selection. It also proposes ambitious experimental evolution and quantitative genetic studies that will empirically measure the net effect of sexual selection on population fitness and extinction. This project aims to catalyse a change in the study of population fitness and address a conspicuous gap in contemporary evolutionary biology.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.
Predicting genetic exchange between species under climate change. This project aims to resolve the factors that lead to the mixing of species’ gene pools, with a focus on whether climate change will increase such mixing, possibly leading to extinction by genetic swamping.
The significance is that the project would improve our understanding of speciation and species’ vulnerability to rapid climate change through genetic mixing; a largely overlooked process.
Key outcomes would be to generate new k ....Predicting genetic exchange between species under climate change. This project aims to resolve the factors that lead to the mixing of species’ gene pools, with a focus on whether climate change will increase such mixing, possibly leading to extinction by genetic swamping.
The significance is that the project would improve our understanding of speciation and species’ vulnerability to rapid climate change through genetic mixing; a largely overlooked process.
Key outcomes would be to generate new knowledge of a fundamental evolutionary process and extend the toolbox of biodiversity managers facing rapid environmental change.
The project would benefit Australia by highlighting our unique biodiversity and scientific capability, and by training early career researchers in advanced evolutionary biology.Read moreRead less

Summary
Eggshells: genetic and biochemical information encapsulated. Tough, waterproof and impervious to decay, extraordinary eggshell can do more than just project baby birds: DNA from eggshells helps wildlife officers to bust wildlife criminals, scientists to investigate the role of humans and climate change in bird extinctions, and conservationists to save our endangered birds.
Faunal responses to environmental change and isolation on an Australian land-bridge island. Establishing how faunas responded to past isolation and environmental changes offers great potential for predicting long-term impacts of habitat fragmentation. By combining novel methods we will track extinction rates, diet and body-size shifts on Kangaroo Island, the only known land-bridge island with a fossil record spanning the past 100,000 years.
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less

How do time, climate change and adaptation shape the assembly and evolution of a diverse continental biota? This project will use new statistical techniques for analysing patterns of biological diversification to test how time, environmental change and evolutionary adaptation shape the accumulation of biodiversity in a continental setting. A supermatrix of genetic and ecological data for Australia's most diverse terrestrial vertebrate group (lizards and snakes) will be compiled.

This project will use new statistical techniques for analysing patterns of biological diversification to test how time, environmental change and evolutionary adaptation shape the accumulation of biodiversity in a continental setting. A supermatrix of genetic and ecological data for Australia's most diverse terrestrial vertebrate group (lizards and snakes) will be compiled. This will allow the testing of the macroevolutionary responses to key environmental changes through the Cainozoic (rapid climatic transgressions and aridification), the relationship between lineage age and species diversity and the effects of major ecological shifts on rates of speciation, extinction and morphological diversification.Read moreRead less
Cuckoo - host coevolution: a model system for investigating the impact of climate change on interspecific interactions and biodiversity. Climate change is causing alterations to the timing of breeding and migration in Australian birds, resulting in mismatches in timing between closely interacting species. This project will assess the impact of climate change on interactions between parasitic cuckoos, hosts and prey and formulate predictions about the long-term viability of these species.

Summary
New approaches to discovering biodiversity and understanding its response to past climate change. New technologies will be used to predict and discover biodiversity hotspots in Australia, especially in the monsoonal tropics. New capacity will be built in biodiversity science, and the results used to improve conservation policy and the effectiveness of conservation planning.
