Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
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.
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
Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosys ....Ancient DNA as a tool to study Australia's paleome: exploring climatic change, past biodiversity, extinctions and long-term survival of DNA. Restoration of Australian ecosystems can only occur if we know what plants, animals and insects used to live in the area before 'pest' species were introduced. This project will use ancient DNA obtained from 'poo' and cave sediments, that is thousands of years old, to discover what species used to live where and when. The ancient DNA profiles of past ecosystems will allow us to make better decisions when trying to establish sustainable and 'natural' mainland and island sanctuaries. Ancient DNA is well preserved in some dry environments; this project will assess DNA preservation from sites all across Australia and use the DNA sequences to discover information about extinct animals and how past climate changes effected the native biota.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
Aboriginal landscape transformations in south-west Australia. This project will inform present day land management strategies by assessing the extent to which the landscape at the time of European colonisation was an artefact of management practices of Indigenous people, .

This project will inform present day land management strategies by assessing the extent to which the landscape at the time of European colonisation was an artefact of management practices of Indigenous people, . The strong Indigenous input, including the detailed recording and analysis of local knowledge together with evidence from archaeological, palaeoenvironmental and historical sources, will reinvigorate Aboriginal connections to land and provide appropriate training for young Indigenous people. The results will also assist in achieving sustainable use of Australia's biodiversity. The importance of human impacts relative to environmental change caused by other factors will improve our national capacity to respond to climate change. Read moreRead less
Human Impact and Environmental Change in the Lower Yangtze Delta, China. Based upon a combination of sediment-based proxies of palaeoenvironmental conditions this project attempts to link existing models of geomorphological and climatic variability for the Yangtze Delta to cultural changes evident in archaeological and historical records. The Yangtze valley was the home of agriculture in Asia and hence for the beginnings of village life and Chinese culture. The delta region has prograded over 10 ....Human Impact and Environmental Change in the Lower Yangtze Delta, China. Based upon a combination of sediment-based proxies of palaeoenvironmental conditions this project attempts to link existing models of geomorphological and climatic variability for the Yangtze Delta to cultural changes evident in archaeological and historical records. The Yangtze valley was the home of agriculture in Asia and hence for the beginnings of village life and Chinese culture. The delta region has prograded over 100 km since the early Holocene and there is a well- preserved succession of Neolithic and modern cultures across its surface. The project investigates the relative impact of Holocene river migration, sealevel and climate change on societies, and also the relative impact of societies on vegetation, eutrophication and erosion while the region was converted to an anthropogenic landscape. The results will enable models of human-environmental interactions to be compared with those developed for
Europe, Africa, Australia and the Middle East.Read moreRead less
The recovery of life recorded at the end-cretaceous impact crater. This project aims to provide new insights into how the Earth and its ecosystems respond to catastrophic events and dramatic shifts in climate. Sharp changes in climate and ocean circulation can place ecosystems under severe stress.

Island resilience to tropical cyclones and rising sea levels. This project aims to produce a dynamic model to address the global problem of low-lying island inundation following high-energy events, such as tropical cyclones and storm surges. These events threaten coastal habitats and biodiversity, and in worst cases, displace human populations.

The pace and rhythm of climate: 600,000 years in a biological hotspot. This project aims to generate knowledge of long-term changes in vegetation and rainfall for the Indo-Pacific Warm Pool (IPWP). The IPWP exerts enormous influence on the Earth’s climate through its interactions with the El Niño-Southern Oscillation, the Austral–Asian monsoons and the Inter-tropical Convergence Zone. Yet despite its importance, the response of the IPWP to global climate change remains uncertain. Through palynol ....The pace and rhythm of climate: 600,000 years in a biological hotspot. This project aims to generate knowledge of long-term changes in vegetation and rainfall for the Indo-Pacific Warm Pool (IPWP). The IPWP exerts enormous influence on the Earth’s climate through its interactions with the El Niño-Southern Oscillation, the Austral–Asian monsoons and the Inter-tropical Convergence Zone. Yet despite its importance, the response of the IPWP to global climate change remains uncertain. Through palynology, ancient sedimentary DNA and compound specific stable isotope analyses, this project aims to produce a terrestrial vegetation, fire and biodiversity record for the last 600 000 years in Sulawesi. The unrivalled length and resolution of this record for the region would make it a benchmark reconstruction of palaeoclimate that may transform our understanding of the IPWP.Read moreRead less
