This project will provide new information for climate change policy development and the goal of an Environmentally Sustainable Australia. It has a strong policy-management imperative, investigating the need for the maintenance and restoration of healthy native vegetation cover as part of Australia’s climate change mitigation and adaptation strategies. Our previous research has shown that land clearing has contributed to climate change, including more severe and persisting droughts, in eastern Australia. Successful implementation of the research findings will lead to an increased ability of regional landscapes to buffer against a more extreme future climate driven by increased concentrations of greenhouse gases.Read moreRead less

A shared mass spectrometer with compound-specific capabilities to support innovative research in biology, the environment and geology: Stable isotope studies have huge and increasing relevance to environmental studies, many of which form the backbone of understanding Australia's terrestrial and marine systems. Compound-specific isotope analysis yields much more information than is available through bulk methods. The problem has been that the separations were labour-intensive and employed complex wet chemistry. New methods reduce the work-load enough to make compound-specific studies possible. In the case of carbon isotopes, new liquid chromatographic technology removes the need for derivatisations which dilute the natural signal and can render it unusable.Read moreRead less
Ancient Ecology: Changes in penguin diet over ~30,000 years in Antarctica. This project proposes the first direct study of ancient ecology using a combination of second-generation DNA sequencing and targeted gene recovery. The food web of the Antarctic Ocean is a classic textbook example of energy and nutrient cycling in the marine environment. Although a great deal is known about the current status of this food web, understanding how this complex set of predator / prey relationships have change ....Ancient Ecology: Changes in penguin diet over ~30,000 years in Antarctica. This project proposes the first direct study of ancient ecology using a combination of second-generation DNA sequencing and targeted gene recovery. The food web of the Antarctic Ocean is a classic textbook example of energy and nutrient cycling in the marine environment. Although a great deal is known about the current status of this food web, understanding how this complex set of predator / prey relationships have changed over long periods of time is vital to understanding the nature of the system itself. The project intends to track changes in the diet of Adélie penguins from serially preserved ancient fecal (guano) remains dating back approximately 30,000 years. These remains are known to contain microscopic remnants of penguin prey.Read moreRead less
Advancing knowledge of microbial symbioses underpinning coral health and reef resilience and predicting their responses to climate change. Coral reefs are complex, diverse ecosystems in which microbial communities form associations with host corals. However, the roles these associations play in coral stress responses are unknown. This project unlocks the black-box of coral microbial complexity and determines how the reef’s smallest members have the greatest influence on reef health.
Global climate change and the impacts of temperature extremes on terrestrial biodiversity. Increasing severity of climate extremes is a disturbing implication of global climate change; yet little is known about the effects of such extremes on the natural world. This project aims to understand the vulnerability of biodiversity to current and future extremes, and to inform conservation efforts and minimise future impacts.

This project will directly benefit the people and businesses associated with 1,174 tropical islands found in Great Barrier Reef and Torres Strait waters. By bringing together a multi-disciplinary team and training young Australian researchers, this project will establish an integrated research program that will outline the challenges, and develop the solutions, that will be needed for Australians to cope with rising sea levels. While the initial focus is the highly exposed tropical islands, the results of this integrated research program will have a wide applicability across Australia in terms of the geomorphological, natural and human challenges associated with rapid pathogenic sea level rise.Read moreRead less
Ecosystem resilience of Shark Bay under changing ocean climate. This project aims to investigate the resilience of the Shark Bay World Heritage Site to projected climate change.

This project aims to investigate the resilience of the Shark Bay World Heritage Site to projected climate change. This project will generate new knowledge for marine conservation through analyses of habitat loss on nutrient budgets and productivity in seagrass and microbialite ecosystems. Expected outcomes are an improved understanding of climate-driven shifts on ecosystem processes in Shark Bay, incorporating science-based evidence for better conservation and management. This will provide significant benefits by contributing to the future-proofing of Shark Bay’s World Heritage values to climate change, and more broadly by demonstrating the consequences of the continued tropicalisation of Australia’s coastline.Read moreRead less

Future fisheries under climate change: the missing role of zooplankton. This project aims to develop the first global ecosystem model with a more realistic representation of zooplankton. Fish are the main source of protein for 3 billion people, yet fish catches are declining. Current models of future fish biomass under climate change do not consider the complex role that zooplankton play in transferring energy from phytoplankton to fish. By resolving the link between phytoplankton and fish, this ....Future fisheries under climate change: the missing role of zooplankton. This project aims to develop the first global ecosystem model with a more realistic representation of zooplankton. Fish are the main source of protein for 3 billion people, yet fish catches are declining. Current models of future fish biomass under climate change do not consider the complex role that zooplankton play in transferring energy from phytoplankton to fish. By resolving the link between phytoplankton and fish, this project will vastly improve estimates of future global fisheries production and regional variation. Such knowledge is vital for future food security in Australia and globally, and also to understand the role of zooplankton in carbon export in the ocean.Read moreRead less
