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
Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they ....Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they do so limits attempts at accurate predictive climate modelling. This project will test conceptual models of SWW dynamics and provide essential boundary conditions for predictive climate models. The project intends to simultaneously build and support a research capacity and global network, and advance Australia’s knowledge and contribution in the area of global climate dynamics.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
