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
A novel approach for assessing environmental flows using satellite data. This project will determine how ecosystems respond to environmental flow by linking flooding history with vegetation responses, using remote sensing, climate data layers, spatial statistics, models of environmental flows and ecological theory. Beneficiaries will include water and land managers in Australia.
Restoring ecosystem function in altered landscapes to achieve ecologicallly sustainable development goals. Mining and agriculture contribute approximately 10 per cent of Australia's gross domestic product. Hence the sustainable development of these sectors is critical to our long term economic growth and well being. However, this growth is leading to degradation of landscape ecosystem function and loss of ecosystem services. Community reaction will curtail production in these sectors where funct ....Restoring ecosystem function in altered landscapes to achieve ecologicallly sustainable development goals. Mining and agriculture contribute approximately 10 per cent of Australia's gross domestic product. Hence the sustainable development of these sectors is critical to our long term economic growth and well being. However, this growth is leading to degradation of landscape ecosystem function and loss of ecosystem services. Community reaction will curtail production in these sectors where function and services continue to be lost. This project addresses the demand for accurate scientific information, needed by industry and government, to understand ecosystem responses to change, and to develop optimal conservation interventions that take account of the costs and benefits in landscapes where the intensive mining industry intersects with extensive land uses for food and fibre production.Read moreRead less

This project aims to identify general properties of body size distributions for thousands of aquatic species by bringing together datasets enabled by global observation and citizen science programs, novel statistical methods and latest theoretical advances. By addressing temperature effects on body sizes, the project expects to generate new knowledge about species status globally, under the combined impacts of climate change and ....Universal properties and application of species size distributions. This project aims to identify general properties of body size distributions for thousands of aquatic species by bringing together datasets enabled by global observation and citizen science programs, novel statistical methods and latest theoretical advances. By addressing temperature effects on body sizes, the project expects to generate new knowledge about species status globally, under the combined impacts of climate change and harvesting. Expected outcomes include new tools to integrate limited body size data into a consistent framework for significance advancement of models used in research and management. This should increase the capacity to assess human impacts on natural ecosystems and predict global warming driven changes.Read moreRead less
Impacts of groundwater extraction on ecophysiology of Australian trees. The aim of this project is to determine the response of trees to the extraction of shallow groundwater. Groundwater-dependent ecosystems rely on a supply of groundwater to maintain ecosystem health, structure and function, and excessive depletion of groundwater resources has a negative impact on these ecosystems. The project intends to combine a field-scale experimental depletion of groundwater resources simultaneously with ....Impacts of groundwater extraction on ecophysiology of Australian trees. The aim of this project is to determine the response of trees to the extraction of shallow groundwater. Groundwater-dependent ecosystems rely on a supply of groundwater to maintain ecosystem health, structure and function, and excessive depletion of groundwater resources has a negative impact on these ecosystems. The project intends to combine a field-scale experimental depletion of groundwater resources simultaneously with alterations in rainfall input and measurements of tree responses. The results of the project are intended to inform industry regulators and the water supply industry on how to improve management of both groundwater and vegetation resources.Read moreRead less
Bad tastes, odours and toxins in our drinking water reservoirs: are benthic cyanobacteria the culprits? Cyanobacteria (blue-green algae) produce toxins and bad tastes that contaminate drinking water sources, cause public concern about water quality. This project will address a critical knowledge gap by investigating species that grow on the sediments of reservoirs, thus providing more comprehensive management solutions to the water industry.
The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interacti ....The ecological impact of large carnivore restoration. This project aims to assess the ecological changes that have arisen due to the repatriation of estuarine crocodiles to Australian ecosystems. It is significant because the restoration provides a rare opportunity to empirically test changes in ecosystem processes under varying degrees of large carnivore predation pressure. Expected outcomes include improved understanding of the processes that govern the strength of predator-ecosystem interactions and an ability to quantify the biomass, social structure, and behaviours of predators required to influence these processes. Benefits should include improvements in how the ecological role of large carnivores is measured, and when and where carnivore populations should be culled or conserved.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.
Planning for the impacts of land-uses on coral reef fisheries. 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 n ....Planning for the impacts of land-uses on coral reef fisheries. 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
