This project will provide new understanding of the role of Australia's only native large mammal predator in sustaining biodiversity and ecological function. This will result in improved management of dingoes as a key part of Australian ecosystems. The project will also test the possibility that relaxation of current controls on dingoes could provide net benefits to beef cattle producers, and thereby improve the viability and sustainability of Australia's cattle-grazing industry.Read moreRead less
Orientation in the pelagic environment: how do larval marine fish find their way home? This study will determine what senses tiny fish larvae use to orientate in the ocean and to influence where currents disperse them. Because larval dispersal determines the spatial extent of fish populations, this knowledge is important for management of marine fisheries and the design and operation of marine parks.
Early warning of cyanobacteria blooms in drinking water reservoirs by means of evolutionary algorithms. Estimated economic cost of cyanobacteria blooms to Australia are at $150 million p.a. Early warning for cyanobacteria blooms will inform water managers to conduct preventive and operational control in reservoirs and water works, and significantly lower risks for public health and costs for monitoring and treatment.

Estimated economic cost of cyanobacteria blooms to Australia are at $150 million p.a. Early warning for cyanobacteria blooms will inform water managers to conduct preventive and operational control in reservoirs and water works, and significantly lower risks for public health and costs for monitoring and treatment. Resulting early warning systems will be novel prototypes for cyanobacteria blooms in drinking water reservoirs based on forecasting models adaptable to environmental and climate change. Model-based scenario analysis will also assist in informed decisions on effects of drought, injection of recycled water and global warming to cyanobacteria growth.Read moreRead less
Using larval connectivity to inform marine reserve network designs in the Coral Triangle. Networks of no-take marine reserves are considered critical tools to ensure conservation and food security targets in the Coral Triangle Region, just north of Australia. More than 1400 community-managed marine reserves have been established in the Philippines, the most populace part of the Coral Triangle. The local conservation and fisheries benefits of these reserves have been well documented. A need now e ....Using larval connectivity to inform marine reserve network designs in the Coral Triangle. Networks of no-take marine reserves are considered critical tools to ensure conservation and food security targets in the Coral Triangle Region, just north of Australia. More than 1400 community-managed marine reserves have been established in the Philippines, the most populace part of the Coral Triangle. The local conservation and fisheries benefits of these reserves have been well documented. A need now exists to convert these individual reserves into operational reserve networks. This project proposes to use new information on larval connectivity, biodiversity and human usage patterns, and local governance networks, to systematically improve the design of an existing Philippine reserve network.

An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host ....An elemental hypothesis for sub-tropical refugia in reef corals. This project aims to discover the underlying traits that permit Australian reef corals to live near the edges of their ranges in relatively cool water. As ocean temperatures warm, novel communities are expected to develop in high latitude ecosystems, which might become important as thermal refugia for low latitude coral reefs. The project aims to test the role of elemental composition (carbon, nitrogen and phosphorus) in coral host and symbiont response to changing water temperature along a latitudinal gradient. The intended outcome of the project is to provide knowledge to support predictions of likely species migrations from tropical to subtropical waters, enabling managers to anticipate the future response of coral communities to seawater warming.Read moreRead less
Pathways to semelparity versus early maturity in animals and plants. The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life hi ....Pathways to semelparity versus early maturity in animals and plants. The project aims to resolve an important but unresolved question in life history evolution and ecology- which mechanisms and constraints lead to semelparity (breeding once, which is rare), and which lead to fast life history (breeding early, which is common) in animals and plants. Theory predicts that both may be adaptations to schedules of adult death. Understanding why males and females have either semelparous or fast life history strategies is crucial to predicting survival of harvested and threatened species under pressure from climate change, drought, predators, and diseases that kill adults. Expected project outcomes include improved ability to address agents of decline of threatened animals and plants including semelparous species.Read moreRead less
Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stre ....Forestry effects on headwater ecosystem health: a multi-catchment experiment. Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stream ecosystems to supplement 4 years of hydrological data collected by Forests NSW from 5 experimental catchments. Results will provide a firmer scientific basis for ecologically sustainable harvesting in this forest type, with flow-on benefits to our national economy, biodiversity, and environment.Read moreRead less

Preserving biodiversity in the face of environmental degradation and climate change is the greatest challenge of our time. Although habitat fragmentation is considered a key cause of the current extinction crisis, the effects of changing habitat configuration on species persistence and recovery is almost completely unknown. Coral reefs are among the most diverse and threatened ecosystems on the planet and this project will provide the first insights into how coral reef fish diversity responds to increased subdivision and isolation of reef habitat. It will identify critical aspects of habitat change that either enhance local diversity or threaten populations with extinction and provide new ecological data to refine conservation strategies.Read moreRead less
