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.
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. The unique data stemming from this multidisciplinary characterisation of the fluxes of organisms recorded at the Chicxulub impact crater could be used to model the fate of life, and the potential to re ....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. The unique data stemming from this multidisciplinary characterisation of the fluxes of organisms recorded at the Chicxulub impact crater could be used to model the fate of life, and the potential to recover from future ecologically turbulent events.Read moreRead less
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.
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

Summary
Past and future dynamics in coastal ecosystems. This project aims to understand how humans and nature affect coastal ecosystems. Globally, billions of dollars are spent on understanding ecosystem services and responses to human and natural pressures, but contemporary datasets’ short time-span makes them inadequate, since ecosystems change at multiple spatial and temporal scales. This project will use seagrass archives to reconstruct the history of coastal ecosystems over millennia, identifying b ....Past and future dynamics in coastal ecosystems. This project aims to understand how humans and nature affect coastal ecosystems. Globally, billions of dollars are spent on understanding ecosystem services and responses to human and natural pressures, but contemporary datasets’ short time-span makes them inadequate, since ecosystems change at multiple spatial and temporal scales. This project will use seagrass archives to reconstruct the history of coastal ecosystems over millennia, identifying baseline conditions, the time-course of ecological change, cycles and thresholds of ecosystem dynamics driven by human and natural forces, and determining their role as biogeochemical sinks. Intended outcomes are to manage ecological change and remove constraints on sustainable coastal development.Read moreRead less
