Summary
Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. ....Dual frequency identification SONAR (DIDSON) facility for sampling benthic and pelagic fish populations. Many Australians enjoy marine and freshwater resources, and we are exploiting fisheries and waterways in particular at an increasing rate. Effective management of fisheries requires understanding the abundance and behavior of fish. This facility will provide novel acoustic video technology for researchers to count fishes and sharks near weirs, under wharves or logs, and within seagrass beds. The dual frequency identification sonar (DIDSON) will also allow accurate and standardised study of fish movements in response to floods, algal blooms or re-stocking events without disturbing the fish or their habitats. This will enhance our understanding of the top-down control by fish of aquatic ecosystems that are directly adjacent to human activity.Read moreRead less
Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal ....Establishing an ecological basis for stocking density of Australian bass in freshwaters: Experimental field tests of a general numerical model. Large numbers of the Australian public go fishing, particularly in rivers and impoundments. Angling in these waterways provides a strong source of income for rural and regional communities. The stocking of native fish to support inland angling also sustains much of the aquaculture industry in western NSW and Queensland. This study will develop an optimal approach to stocking Australian bass which is relevant for other stocked freshwater species, and will allow stocking to be undertaken in an environmentally responsible manner. This will both enhance the outcome of investment of public funds in stocking, and enhance the recreational fishing experience that is so important to rural regional communities.Read moreRead less
Fine-scale responses of freshwater fish to environmental flows in arid-zone rivers and wetlands. The community is demanding that river health be improved to sustainable levels through increased river flows. This will come through the efficient use of available environmental water that supports the ecology of Australia's river systems. This project will substantially inform the operational management of water for native fish populations and other organisms to specific wetlands and will guide the ....Fine-scale responses of freshwater fish to environmental flows in arid-zone rivers and wetlands. The community is demanding that river health be improved to sustainable levels through increased river flows. This will come through the efficient use of available environmental water that supports the ecology of Australia's river systems. This project will substantially inform the operational management of water for native fish populations and other organisms to specific wetlands and will guide the delivery of environmental flows to maintain native fish stocks. The project will help management of declining fish populations and more generally wetlands by improving our understanding of the role of environmental flows.Read moreRead less
Investigation of endocrine disruption in Australian aquatic environments. Water is a vital resource. The disposal of wastes is often associated with the release of contaminants like endocrine disruptors into the environment. These contaminants can impact the health of our waterways and lead to potential risks to fish populations and ultimately public health. The hazards resulting from endocrine disruptors have been well defined globally and to a lesser extent in Australia in the last decade, how ....Investigation of endocrine disruption in Australian aquatic environments. Water is a vital resource. The disposal of wastes is often associated with the release of contaminants like endocrine disruptors into the environment. These contaminants can impact the health of our waterways and lead to potential risks to fish populations and ultimately public health. The hazards resulting from endocrine disruptors have been well defined globally and to a lesser extent in Australia in the last decade, however we have very limited information about possible effects in Australian waterways or reservoirs. This research project will investigate the state of endocrine disruption in our waters. The knowledge gained will address this gap and provide a benefit to the national community, risk managers and importantly our waterways.Read moreRead less

Identifying and managing the ecological impacts of free-ranging wild horses. Wild horses cause significant ecological damage in conservation areas in Australia, but experimental research examining horse impacts is lacking. Our approach is to assess ecological impacts of wild horses in Guy Fawkes River National Park, a significant wilderness in northern NSW. We will describe the relationship between horse abundance and environmental impacts, experimentally determine how horse exclusion affects ....Identifying and managing the ecological impacts of free-ranging wild horses. Wild horses cause significant ecological damage in conservation areas in Australia, but experimental research examining horse impacts is lacking. Our approach is to assess ecological impacts of wild horses in Guy Fawkes River National Park, a significant wilderness in northern NSW. We will describe the relationship between horse abundance and environmental impacts, experimentally determine how horse exclusion affects key environmental variables, and test the sensitivity of threatened plants to wild horse browsing and trampling. A key outcome will be development of scientifically-validated protocols for assessing horse impacts, and for managing wild horses in other areas of eastern Australia.Read moreRead less
Do dingoes regulate the structure of arid ecosystems? Predation by the red fox and land degradation due to overgrazing have been identified as major factors contributing to the loss of biodiversity in arid Australia. I hypothesise that dingoes by regulating populations of foxes and herbivores may have positive effects on biodiversity. If this hypothesis is supported, this project will have great significance for biodiversity conservation and is likely to irrevocably change land and wildlife man ....Do dingoes regulate the structure of arid ecosystems? Predation by the red fox and land degradation due to overgrazing have been identified as major factors contributing to the loss of biodiversity in arid Australia. I hypothesise that dingoes by regulating populations of foxes and herbivores may have positive effects on biodiversity. If this hypothesis is supported, this project will have great significance for biodiversity conservation and is likely to irrevocably change land and wildlife management practices in Australia. The recommendations arising from this research will influence policy on land management and contribute to achieving an environmentally sustainable Australia.

An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current res ....An innovative approach to maximising catchment water yield in a changing climate. Australia is facing a crisis in water availability and management within many of the continent's major cities and the Murray-Darling and Sydney Basins. Risk to water resources will also be exacerbated by climate change. Past solutions of increasing water supply by building dams are no longer easily implemented because of the significant environmental consequences. To maximise yield, better management of current resources is required, dependent on understanding what factors affect water yield and how they may be better manipulated. This project innovatively integrates ecological and hydrological processes by modelling the expression of water use by vegetation and its management and water availability at fine resolutions.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. 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.

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
