Range dynamics and demographics of spatially structured populations under global change. Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, ra ....Range dynamics and demographics of spatially structured populations under global change. Why are particular species present in some locations, but not others? This is a simple, fundamental ecological question, yet surprisingly, our answers on this point remain far from complete. Using an integrated, systems-based approach, we will determine the interplay between: (i) birth, death and movement rates, (ii) species interactions, and (iii) the constraints of the physical environment (temperature, rainfall, soil type), which determine the limits of species' ranges. Our models will provide Australian conservation managers with a novel, validated toolbox to explore the trade-offs, and synergies, inherent in trying to adapt to climate change and other stressors on biodiversity.Read moreRead less
Planning for a transformed future: Modelling synergistic climate change and land use impacts on biodiversity. Climate change poses a dire threat to Australia's biodiversity and natural resources due to its all-encompassing reach and the speed at which human-driven changes are taking place in already heavily modified systems.

Climate change poses a dire threat to Australia's biodiversity and natural resources due to its all-encompassing reach and the speed at which human-driven changes are taking place in already heavily modified systems. The proposed research, on modelling the synergistic impacts of anthropogenic threats, will provide new knowledge and innovative solutions for protecting unique ecosystems facing severe environmental challenges this century. The validation of these new methods, which aim to capture ecological responses to global change, will represent a major and timely addition to the national research capability on climate change adaptation, and add to Australia's reputation as a global leader in the field of ecology.Read moreRead less
Towards a predictive model for coastal marine microbial assemblages. Coastal regions are overwhelmingly the most intense point of interaction between human activity and oceanic provinces. At this interface, the marine biological ecosystem provides critical services that are required to maintain industrial, economic and social well-being. Our work will identify how these marine systems respond to anthropogenic and climatic variability, National Research Priority 1, and in turn, how this response ....Towards a predictive model for coastal marine microbial assemblages. Coastal regions are overwhelmingly the most intense point of interaction between human activity and oceanic provinces. At this interface, the marine biological ecosystem provides critical services that are required to maintain industrial, economic and social well-being. Our work will identify how these marine systems respond to anthropogenic and climatic variability, National Research Priority 1, and in turn, how this response affects ocean services. This knowledge will inform management efforts in resource and biodiversity conservation, and identify novel areas for future resource exploration.Read moreRead less
Understanding the ecological resilience of nearshore marine communities. Our thinking about climate change and its effects on marine ecosystems is shifting from considering how we can prevent it occurring to understanding how natural systems might adapt to climate change, or how we might improve the ability of these ecosystems to recover, that is, their resilience to change. In many shallow water ecosystems, one or a few key species provide habitat structure that in turn determines the abundanc ....Understanding the ecological resilience of nearshore marine communities. Our thinking about climate change and its effects on marine ecosystems is shifting from considering how we can prevent it occurring to understanding how natural systems might adapt to climate change, or how we might improve the ability of these ecosystems to recover, that is, their resilience to change. In many shallow water ecosystems, one or a few key species provide habitat structure that in turn determines the abundance of a wide range of other species. This proposal will take two important temperate marine 'engineers' and identify the factors that make them most resilient.Read moreRead less
You are what you eat: can tissues of top predators which show sequential dietary change identify long-term trends in ecosystems? This project uses stable isotope signatures in the whiskers of top predators to determine foraging ecology. We aim to validate current stable isotopic models so this cost-effective tool can be used to examine large scale changes in food web dynamics in one of the world's climate hotspots in the Antarctic. Changes in the Antarctic directly impact the Australian communit ....You are what you eat: can tissues of top predators which show sequential dietary change identify long-term trends in ecosystems? This project uses stable isotope signatures in the whiskers of top predators to determine foraging ecology. We aim to validate current stable isotopic models so this cost-effective tool can be used to examine large scale changes in food web dynamics in one of the world's climate hotspots in the Antarctic. Changes in the Antarctic directly impact the Australian community as our climate is affected by changes in Antarctica. As this project is part of an International Polar Year Program, Impact of CLImate induced glacial melting on marine and terrestric COastal communities on a gradient along the Western Antarctic PENinsula (ClicOPEN), it strengthens Australia's international scientific links and exposes Australia's future scientists to internationally collaborative research which is of global significance.Read moreRead less
Multi-Scale Analysis of the Vulnerability of Coral Reefs to Ocean Acidification. The Great Barrier Reef (GBR) is one of Australia's biggest icons, and represents more than 10% of the world's coral reefs. It is a World Heritage Area and is home to more than 1 million species. The GBR provides Australia with more than $6 billion in annual national revenue. To help manage for sustained resilience of the GBR in an era of climate change, Australia needs to understand the major threats, in particular ....Multi-Scale Analysis of the Vulnerability of Coral Reefs to Ocean Acidification. The Great Barrier Reef (GBR) is one of Australia's biggest icons, and represents more than 10% of the world's coral reefs. It is a World Heritage Area and is home to more than 1 million species. The GBR provides Australia with more than $6 billion in annual national revenue. To help manage for sustained resilience of the GBR in an era of climate change, Australia needs to understand the major threats, in particular ocean acidification. By producing an innovative framework for assessing acidification risks, the project will help Australia demonstrate continued stewardship of one of the world's richest and most sensitive ecosystems.Read moreRead less
Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exp ....Reconstructing past population dynamics to understand human and climatic impacts in prehistory. More than 100 species have become extinct since humans first colonised Australia, and over 1000 are considered threatened. This research will determine the factors most strongly governing the interaction between humans and native fauna in Australia over the last 46 millennia. Our approach is powerful and novel because it will effectively draw together multidisciplinary evidence on natural resource exploitation and habitat alteration by ancient people, and the influence of dramatic climatic shifts on the Australian biota. Information on past biological responses to environmental change is critical to properly contextualising the current impact, and long-term consequences of, threats such as global warming, habitat loss and invasive species.Read moreRead less
