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
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
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
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.

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
Novel governance for marine ecosystems in rapid transition. This project will develop the governance knowledge required to manage rapidly changing marine ecosystems.

This project will develop the governance knowledge required to manage rapidly changing marine ecosystems. Australia has the third largest marine estate globally, and its ecosystems support critical economic and sociocultural values. However, human pressures are tipping marine ecosystems into alternate states, inspiring new interventions to sustain industries and communities. New interventions necessitate transitions in governance. Expected outcomes include a comparative understanding of novel marine interventions now underway globally, and practical guidance on how to diagnose and implement responsible marine governance. Significant benefits include enhanced governance and sustainability of Australian and international marine ecosystems.Read moreRead less

This project intends to maximise the scope for rebuilding reef fisheries while ensuring short-term levels do not become too low. Like many developing countries, Indonesia wishes to rebuild its heavily over-exploited coral reef fisheries. Marine reserves allow fish populations to recover and replenish fished areas. However, because reserves remove fishing grounds, fish catches tend to decrease in the short-term while fish recover in reserves; a process that can take a decade. Loss of yield can be so burdensome that managers abandon fisheries. This research is intended to improve the economic security of fishers and food security, and inform World Bank and Australian aid programs.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.

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

This project intends to quantify the role that aquatic habitats play in fisheries, and to help identify where to restore degraded aquatic habitats. Fisheries are a globally important resource but their status is declining in many regions, often because of the loss of aquatic habitats. However, the role of habitat in fishery declines is poorly quantified, and new models are needed that integrate existing datasets to attribute change in a fishery to change in its habitats. The project aims to develop a new statistical analysis to examine the role of habitat loss in the global status of fisheries and how multiple human impacts to habitats affect fisheries, to decide how we can best protect aquatic habitats.Read moreRead less
