The recent anthropogenic global warming is causing polar icecap melting, sea level rise, reef coral bleaching and degradation, and increased frequency and intensity of severe droughts, floods, tropical cyclones/hurricanes/typhoons in the past decades, focusing daily media headlines worldwide. Our study will enhance understanding of global climate change, El Niño and Asian-Australian monsoon variability and coral reef degradation, and provide improved knowledge for future predictions. The outcome will impact on our National Research Priority 1: An Environmentally Sustainable Australia, enhance Australia's leadership in coral reef research, and contribute to an improved relationship with our neighbours in science, education and training.Read moreRead less
Assimilating development objectives in conservation planning. This project will extend the theory and practice of decision science to explore the question of how the apparently divergent objectives of biodiversity conservation and economic development can be balanced.

This project will extend the theory and practice of decision science to explore the question of how the apparently divergent objectives of biodiversity conservation and economic development can be balanced. The human modification of natural landscapes is causing species loss to accelerate. Yet land use and infrastructure developments are often necessary to support economic growth. The project plans to develop new methods to map past and project future development scenarios for the lower Mekong region in south-east Asia, a globally significant region undergoing rapid economic development. Novel problem formulations would be used to balance biodiversity conservation with development objectives.Read moreRead less

Tipping points and early warning signals in complex ecosystems. This project aims to create a theory of early warning that uses spatial data available on system state, connectivity and environmental stress, and to create tools to infer the risk of ecosystem collapse. Many ecosystems have irreversible tipping points. Since their locations are often unknown, metrics may provide an early warning of collapse but are difficult to apply because they need long time series which are usually lacking. Thi ....Tipping points and early warning signals in complex ecosystems. This project aims to create a theory of early warning that uses spatial data available on system state, connectivity and environmental stress, and to create tools to infer the risk of ecosystem collapse. Many ecosystems have irreversible tipping points. Since their locations are often unknown, metrics may provide an early warning of collapse but are difficult to apply because they need long time series which are usually lacking. This project will use the Great Barrier Reef as a testbed because it has both long time series (standard approach) and rich spatial data (new approach), and exhibits early warning signs. We will use these tools to gauge whether symptoms on the Great Barrier Reef predict local collapse and to develop intervention plans.Read moreRead less
Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offsho ....Impact of increased sediment and nutrient discharges on the long-term sustainability of the Great Barrier Reef. The Great Barrier Reef, one of Australia's greatest natural assets, is under increasing threat from extreme climatic events caused by global warming and from land-based pollution. This research will identify the main sources of sediment and nutrient pollution caused by river runoff and by how much this has increased above 'natural levels'. We will discover how the very sensitive offshore coral reefs have responded to increased pollution and whether this is the cause of the very devastating crown-of-thorn-starfish infestations. Understanding the long-term effects of land-based pollution on the ecology of coral reefs in the GBR will thus provide a scientific basis to help ensure that it has a sustainable future.Read moreRead less
Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size dis ....Linking phytoplankton to fisheries using zooplankton size spectra. This project aims to develop innovative numerical methods to understand the dynamics, carbon export, and trophic structure of zooplankton. The trophic links between phytoplankton, zooplankton and fisheries are unknown. The size- frequency distribution of zooplankton (size spectrum) is an innovative method for estimating their growth, predation and production as food for fish. Analysis of a global synthesis of zooplankton size distributions from tropical to polar environments are expected to reveal these vital rates of pelagic ecosystems. The zooplankton rates will reveal, for the first time, the link between phytoplankton and fisheries, and will significantly improve ecosystem models and global assessments of environmental change.Read moreRead less
THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES. The objective of this proposal is to quantify the environmental impacts of enhanced terrestrial fluxes and climate change on the coral reefs in the Great Barrier Reef. This will be achieved by using an integrated approach based on coral proxy records of river plumes and sea surface temperatures that are preserved in carbonate skeletons of the long-lived (200-400 year old) Porites coral. ....THE CORAL RECORD OF ENVIRONMENTAL IMPACTS IN THE GREAT BARRIER REEF:QUANTIFICATION OF ANTHROPOGENIC FLUXES.

This project is designed to examine the distribution and redistribution of risk associated with environmental change and large scale development interventions in the Mekong Region. The research aims to make a theoretical contribution to the rapidly emerging field of political ecology, by moving beyond an analysis of winners and losers based on certainty and post-facto impacts. The study will work toward an analysis driven by the inherent uncertainties that underlie both the social construction and social distribution of environmental risk. The research also has important practical implications for environmental and social assessment methodologies in and beyond the case study region.Read moreRead less
Designing landscapes to deliver ecosystem services to agriculture. This project addresses the Priority Goal of Sustainable Use of Biodiversity by employing a pioneering management framework that identifies situations where agriculture can gain maximum benefit from nature's services.

This project addresses the Priority Goal of Sustainable Use of Biodiversity by employing a pioneering management framework that identifies situations where agriculture can gain maximum benefit from nature's services. Services like pollination are crucial; approximately 35% of global food production comes from crops pollinated by bees or birds. These services contribute billions of dollars to production. Our model will greatly enhance the flow of services from nature to agriculture by linking land-use options with service availability. This will improve economic returns to local communities and agricultural industries, and promote protection of native species by recognising their contribution to agriculture. Read moreRead less
