Global Climate Change, Carbon Dioxide (CO2), and the Evolution of Life in the Palaeozoic and Early Mesozoic. A critically important problem directly affecting our society is the effects of climate change on our life support systems and environment. But the impacts of climate change and increasing carbon dioxide (CO2) on the Earth's biosphere are not well understood, so much can be learnt from examining past events that have shaped its evolution.

A critically important problem directly affecting our society is the effects of climate change on our life support systems and environment. But the impacts of climate change and increasing carbon dioxide (CO2) on the Earth's biosphere are not well understood, so much can be learnt from examining past events that have shaped its evolution. Our research will provide important new insights into how life evolved and survived periods of major environmental upheaval in Earth history, especially its responses to large shifts in global temperatures and atmospheric CO2. These outcomes will provide valuable input to help project how future global warming and rapidly increasing carbon dioxide levels will likely impact our modern biosphere.Read moreRead less
Molecular fossils, the evolution of Earth's early oceans and the origin of the oldest oil. Australia retains undiscovered oil reserves. We believe that a change in primitive marine life forms may have fundamentally changed the chemistry of the Earth's oceans and is responsible for the world's oldest oil reserves. While these reserves have been found, and successfully commercialised, overseas, similar reservoirs in Australia remain elusive. The project will develop and apply technologies based on ....Molecular fossils, the evolution of Earth's early oceans and the origin of the oldest oil. Australia retains undiscovered oil reserves. We believe that a change in primitive marine life forms may have fundamentally changed the chemistry of the Earth's oceans and is responsible for the world's oldest oil reserves. While these reserves have been found, and successfully commercialised, overseas, similar reservoirs in Australia remain elusive. The project will develop and apply technologies based on hydrocarbon biomarkers to help determine the oil-producing rock types of Precambrian sedimentary rocks. This allows us to estimate the oil's age and predict where petroleum reservoirs may be hidden. PhD students involved in the project will gain valuable knowledge about the link between changes in ecology and the carbon cycle.Read moreRead less
Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not h ....Transformation of vegetation by big herbivores, from the Pleistocene to now. The project aims to provide a coherent understanding of the effects of extinct and extant large herbivores on ecosystems over space and time. The structure and distribution of vegetation types is determined not only by climate and soils, but also by the impacts of herbivores and fire as consumers of plant biomass. Recent research has shown how fire shapes the large-scale distribution of vegetation types, but we do not have an equivalent understanding of the effects of large ground-dwelling herbivores. The project plans to test the effects of such animals on vegetation structure in the Pleistocene, when mega-herbivores were common, and today, and thus to compare the impacts of fire and herbivores on the distribution of vegetation types.Read moreRead less

Plant species vary widely in quantitative functional traits. Global datasets about functional variation are emerging, with Australian and NZ leadership. A network would be supported in both Australia and NZ and with strong links elsewhere. It would target seven ambitious but achievable research developments. Each of them demands intensive conversation between separate disciplines. Networking across all seven strands will create a broader linkage, spanning across palaeobiology, ecosystem function, vegetation structure, global change, ecophysiology, phylogeny, genomics, ecoinformatics and evolutionary theory.Read moreRead less

The rise of algae and the emergence of animals. This project aims to uncover the environmental changes that transformed the oceans 650 million years ago when complex algal cells started to replace bacteria as the dominant forms of life. Using a groundbreaking combination of molecular fossils and isotopes from ancient sedimentary rocks, the project aims to reveal how the flow of energy changed through Earth’s ecosystems. The expected outcomes include new knowledge about our own origins and the ev ....The rise of algae and the emergence of animals. This project aims to uncover the environmental changes that transformed the oceans 650 million years ago when complex algal cells started to replace bacteria as the dominant forms of life. Using a groundbreaking combination of molecular fossils and isotopes from ancient sedimentary rocks, the project aims to reveal how the flow of energy changed through Earth’s ecosystems. The expected outcomes include new knowledge about our own origins and the events that led to the emergence of the first animals. Additionally, new insights about the mechanisms that generated the oldest hydrocarbon reserves may lead to a new biomarker tool to aid discovery of major new oil or gas reserves in Australia’s Red Centre.Read moreRead less
Uncovering the evolutionary history of Australasian marsupials: combining molecular phylogenetics and ecological inference. Marsupials are symbolic of the uniqueness of Australia's biological systems and there is widespread public interest in their natural history.

Marsupials are symbolic of the uniqueness of Australia's biological systems and there is widespread public interest in their natural history. Yet we know little of the evolutionary mechanisms that have shaped their biodiversity. This is a critical problem when considered in the context of Australian marsupials having suffered the highest extinction rate of any continental mammal fauna over the past 200 years. This project will make a major contribution to understanding the origins, timescale and ecological nature of Australasian marsupial evolution. In doing so, it will inform conservation strategy, promote Australasian marsupials as a model system for studying faunal coevolution and develop widely applicable bioinformatic tools.Read moreRead less

This project aims to discover microbiological processes involved in ore formation in order to understand how zinc and lead minerals formed in the sediments of Australia’s ancient seas. The apparent ‘Boring Billion’ – the geological period 1800 to 800 million years ago – may have harboured seas of fluctuating colours. Fossil biomolecules, unearthed from 1.6 billion years old sediments, draw a picture of ancient seas oscillating between blooms of purple and green bacteria, with waters rapidly alternating between toxic and sulphidic and rich in dissolved iron. Based on these observations, the project aims to discover the dynamic nature of primordial ecosystems, investigate how ancient seas were controlled by the Earth’s orbit around the sun, and explore how microorganisms may have formed the world’s largest zinc deposits.Read moreRead less
