This projects aims to develop models that can determine the ecological and economic impacts of land-use changes (e.g. agriculture) on fisheries and assess alternative land-use plans that seek to maximise economic opportunity while protecting fisheries. Fisheries support the livelihoods of 12 per cent of the world’s population. Land-based activities are among the most significant threats to coral reef fisheries because sediments and nutrients degrade reefs, yet they are often ignored in fisheries management. By improving the sustainability of coastal development, biodiversity conservation, and health of fisheries, the models developed by the project could deliver socio-economic and environmental benefits for millions of people reliant upon fisheries for their livelihoods.Read moreRead less

This method will dramatically improve the speed, and power of environmental impact assessments, permitting responsible resource development with major benefits to industry and the economy. It will also create new tools to improve water management and quality, biosecurity, forensics/policing and human health, as reflected by the diverse range of industry partners supporting this project.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

Summary
Coral reefs, climate change and land-based pollution: past, present and future impacts on coral reef development. Major threats to the Great Barrier Reef (GBR) include climate change and deteriorating water quality. Environmental histories in the skeletons of reef building organisms will be used to determine how past, present and future environmental threats influence the growth and development of the GBR. Findings will help set national water quality targets.
Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in ....Seagrass tolerance of oil spills - scaling of pollution impacts. Seagrasses provide vital ecosystem services (such as sediment stabilisation and habitat provision) in Australian coastal waters. The contribution of pollutants to current seagrass decline is poorly understood. The Australian shipping industry is the 5th largest in the world but there is very little data on the impacts of petroleum hydrocarbons on intertidal seagrasses and hence no information for coastal resource managers to use in decision-making in the event of an oil spill. This project will assess the relative toxicities of a number of petroleum hydrocarbons on Australian seagrass species to provide necessary data for the development of effective management practice.Read moreRead less

Antarctic krill are an important species in the Southern Ocean supporting most of the Antarctic birds and mammals. A sustainable krill fishery is developing with krill products used in aquaculture and increasingly for human consumption. A new omega 3 krill oil industry has emerged and is rapidly expanding. The aim of the project is to predict the factors governing oil levels and the biochemical composition in krill which will help us understand growth, reproduction and recruitment. The research aims to also assess the possible effects of climate change on krill. Outcomes of this research aim to be used to manage the expanding krill fishery.Read moreRead less

The project demonstrates how evaluation can lead to improved management of protected areas. Effectively managed protected areas are essential for biodiversity conservation. Improved management, and hence improved conservation outcomes will flow from enhanced use of monitoring and evaluation data in decision-making. Identifying strengths and weaknesses in management will allow managers to better allocate resource for more effective conservation outcomes. The project establishes connections with all protected area management agencies in Australia, and will contribute to the development of national policy and practice in protected area evaluation and reporting, thus helping to meet national and international reporting obligations.

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.
