Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for p ....Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for predicting climate change resilience that can be applied to many species. The intended benefits include increasing our understanding of the potential for native bees to act as future pollinators in Australia’s natural and agro-ecosystems, and guide policy and management decisions to better protect and conserve our bee fauna.Read moreRead less
Frayed at the edges? Integrating evolutionary genetics into the study of species distributional limits. Restricted species, like those in rainforests, represent the vast majority of biodiversity, but they face high risks of extinction due to climate change unless they can adapt. Using butterflies as a model, this project will examine whether rainforest restricted species are able to adapt to future climate change and provide insight into their extinction risk.
Evolving landscapes of our early South African ancestors. This project aims to reconstruct the early evolution of our genus, from 2.6 to 1.8 million years ago. This was a time of faunal and environmental change, the extinction of apelike human ancestors (Australopithecus), the speciation of a specialised human genus, Paranthropus, and the origin of our own genus, Homo. This project will study South African cave sites, the surrounding karst, and the oldest known Homo ergaster fossil to model chan ....Evolving landscapes of our early South African ancestors. This project aims to reconstruct the early evolution of our genus, from 2.6 to 1.8 million years ago. This was a time of faunal and environmental change, the extinction of apelike human ancestors (Australopithecus), the speciation of a specialised human genus, Paranthropus, and the origin of our own genus, Homo. This project will study South African cave sites, the surrounding karst, and the oldest known Homo ergaster fossil to model changing dietary patterns and landscape use by hominins. This project expects to reconstruct the early evolution of our genus and to address how species reacted to changing environmental conditions and increasing aridity.Read moreRead less
Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this ....Size matters: evolution of body size of species in deep time. Global warming is predicted to form 'sick seas' and cause widespread stunted growth of taxa and ecosystem-wide dwarfism. Exactly how this works requires substantiation of both short-term empirical and experimental research as well as evidence from the deep-time fossil record. Using the high-resolution marine fossil record from the Permian-Triassic mass extinction ~252 million years ago, the most severe in the history of animals, this project will investigate how body size of marine species and communities evolved in response to the mass extinction and rapid global warming. It is expected that the project findings will help better understand the links between global warming, anoxia, hypercapnia, euxinia, ocean acidification, and species adaptation and evolution.Read moreRead less
Modelling policy interventions to protect Australia's food security in the face of environmental sustainability challenges .

In collaboration with an advisory committee it will specify and prioritise policy solutions in terms of their social and economic credentials.
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

Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify h ....Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify how distinct factors-including climate, recruitment, and disturbance-enhance the race for light and can thereby explain the origins of Australia's giant Eucalypt. With calibrated models of species evolution, coupled with targeted fieldwork and big data, this project clarifies key forces shaping present and future vegetation.Read moreRead less
Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aim ....Ocean heat content change and its impact on sea level. This project aims to improve projections of possible sea level changes. Sea level rise is among the most significant potential impacts of transient climate change around the world. Poor understanding of the way in which heat is absorbed at the sea surface and distributed by ocean circulation is a leading source of uncertainty in projections of global surface temperature and regional sea level rise by the end of this century. This project aims to apply novel observational methods, complimented by numerical modelling, to quantify the drivers of recent change. This project expects to transform our ability to predict how ocean temperature and sea level will change in the future.Read moreRead less
