In Australia $20 million was spent on weed control in natural areas in 2001-02 and is indicative of the level of funding for weed control programs each year. An understanding of how current weed control programs affect the regeneration of weeds in the system will give us novel insights into the persistence of weed populations despite sustained investment in control. Environmental weeds threaten biodiversity and ecosystem function in unique Australian communities, better management of weeds will have conservation, ecosystem service provision and amenity values nationally. This project highlights the importance of understanding the weed regeneration niche for successful long-term and sustainable control.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.

Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by provid ....Density regulation as a major determinant of population persistence: advancing empirical and theoretical approaches to conserve biodiversity. Without efficient application of limited conservation resources, more species will go extinct and invasive species will continue to proliferate. With a better understanding of extinction processes, a higher benefit:cost ratio will ensure better outcomes for biodiversity. We will directly address (1) the sustainable use of Australia's biodiversity by providing evidence-based support for minimum viable population size targets to avoid extinction; (2) responding to climate change by determining the species- and environmentally specific contexts leading to elevated risks of extinction; and (3) protecting Australia from invasive diseases and pests by determining density targets that maximise eradication success.Read moreRead less
Restoring hydrological connectivity of surface and ground waters: Biogeochemical processes and environmental benefits for river landscapes. This project examines the restoration of lateral hydrological connectivity to improve floodplain structure and function. The connections between stream flows and both shallow groundwaters and floodplains are critical in sustaining river landscapes. Degrading land and water management practices compounded by natural climatic extremes have severed this link. ....Restoring hydrological connectivity of surface and ground waters: Biogeochemical processes and environmental benefits for river landscapes. This project examines the restoration of lateral hydrological connectivity to improve floodplain structure and function. The connections between stream flows and both shallow groundwaters and floodplains are critical in sustaining river landscapes. Degrading land and water management practices compounded by natural climatic extremes have severed this link. Restoring hydrological connectivity is vital for replenishing groundwater storage and increasing base flows that affect fundamental riverine processes. Using an innovative approach to sustainable agriculture, our project unites multidisciplinary scientific and industry expertise to investigate the biogeochemical and biophysical effects of secondary floodplain channels and in-stream structures on riverine groundwater processes.Read moreRead less

Blooms of the toxic cyanobacterium Lyngbya majuscula in Australia coastal waters are resulting in severe ecological and economic impacts, including significant human health problems. What is urgently needed is the capacity to predict the onset of a Lyngbya bloom and the development of management strategies to reduce or control blooms. We have assembled a dynamic team of active and experienced researchers using various state-of-the-art technologies to elucidate the key factors contributing to Lyngbya blooms and have industry partners willing to implement large scale testing of various controls. We have a unique opportunity to potentially solve a pressing environmental problem.Read moreRead less
Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently availabl ....Monitoring organic matter in drinking water systems using fluorescence spectroscopy: improved early warning, process optimisation and water quality. Climate change is contributing to elevated organic matter (OM) concentrations in drinking water supplies. If insufficiently treated, OM can lead to unacceptable concentrations of disinfection by-products, considered to be potential carcinogens, as well as taste and odour problems and bacterial re-growth in the distribution system. Currently available on-line monitoring techniques give limited information regarding the nature of OM; however, fluorescence spectroscopy has shown promise in this regard. Hence, this project aims to provide an on-line monitoring protocol utilising fluorescence to aid utilities in their provision of safe drinking water, thus addressing the National Research Priority goal water – a critical resource.Read moreRead less
Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as ....Extrinsic threats and biological predisposition in animal extinction and rediscovery. A global extinction crisis looms, and Australia has a shocking record, especially of mammal extinctions. The results of this project to find how different threats affect each species will lead to management that focusses on species- and region-specific causes. This will help to prevent further extinctions of Australian mammals and other fauna. Many people hope that species of particular importance to us such as the thylacine have defied extinction, and will be rediscovered. This project will test which predictive factors can increase the chance of species rediscovery, and help management agencies plan for the expected number of future rediscoveries.Read moreRead less
