This project intends to develop a conservation management tool for use in fire-prone fragmented landscapes to reverse biodiversity loss. It will address two critical knowledge gaps: the combined effects of fire and fragmentation on animal movement, and the implications of current and future fire regimes for native animal populations. Land-use change has severely fragmented 40% of Australia’s natural landscapes, resulting in loss of habitat for native biodiversity. Remaining habitat fragments are at risk from increases in the frequency and intensity of fire, which also threatens biodiversity. The anticipated outcome is a conservation management tool that is readily transferable to any fire-prone system.Read moreRead less
Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and sourc ....Native fish stocking of rivers: discriminating between hatchery-reared and wild fish. Stocking of fish is widely used in attempts to restore native fish populations. Little is known of the fate of stocked fish or the effects of stocking on resident populations. We will develop and evaluate protocols for chemical marking of otoliths of hatchery-reared fish so that their source can be determined. Experimental stocking of hatchery-reared fish will be undertaken and population structure and source of stocked versus wild fish determined in stocked and unstocked rivers. Natural chemical signatures will also help determine important recruitment areas. The outcomes will allow fisheries managers to make informed decisions regarding stocking strategies.Read moreRead less

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. Resulting early warning systems will be novel prototypes for cyanobacteria bloo ....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. 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
Conservation management of the endangered Pygmy Bluetongue Lizard. There is a second chance to rescue a lizard species that was recently considered extinct. This project builds on biological knowledge about the lizard to develop programs for monitoring and maintaining viable populations, to advise landholders of management options, and to inform and involve local communities in conservation action.
Effects of urbanisation and introduced species on rivers and estuaries: a whole of catchment approach. Humans have converted land into urban and agricultural areas, as well as intentionally or accidentally introduced species into aquatic systems. Estuaries and rivers are some of the most degraded systems on earth and fishes are among the most endangered vertebrates worldwide. We will utilise novel modelling techniques to provide predictive models that investigate fish-environment relationships. ....Effects of urbanisation and introduced species on rivers and estuaries: a whole of catchment approach. Humans have converted land into urban and agricultural areas, as well as intentionally or accidentally introduced species into aquatic systems. Estuaries and rivers are some of the most degraded systems on earth and fishes are among the most endangered vertebrates worldwide. We will utilise novel modelling techniques to provide predictive models that investigate fish-environment relationships. We will also investigate impacts of trout introductions on native fish including dietary, competitive and assemblage level changes to the system. Essential data for the sustainable management of freshwater and estuarine systems will be obtained, which will lead to an environmentally sustainable Australia. Read moreRead less
Conservation management of the endangered skink Liopholis slateri. Slater's skink was common in Central Australia 30 years ago, but is now endangered. The project will investigate the lizard response to changing environmental conditions and will develop biological insights that will be important for its conservation.
Temperate trophic cascades: impacts of seal foraging on benthic community dynamics. Effective Marine Protected Area management across Australia requires guidance from rigorous strategic research. The project will investigate opposing activities that provoke ecosystem collapse (overharvesting, grazing) or recovery (marine park protection) and provide advice to improve effectiveness of marine conservation strategies in New South Wales and South Australia.
Sediment-derived scenarios of wetland status and change, the Lower River Murray, SA. River Murray wetlands changed early in European settlement so the pre-impact conditions are invisible to managers relying on anecdote or monitoring. Baseline conditions of wetlands can be derived from ecological archives preserved in sediments. Fossil diatom assemblages, reflective of past water quality, and other fossils, will be exhumed from sediment sequences to reconstruct wetland conditions. The integration ....Sediment-derived scenarios of wetland status and change, the Lower River Murray, SA. River Murray wetlands changed early in European settlement so the pre-impact conditions are invisible to managers relying on anecdote or monitoring. Baseline conditions of wetlands can be derived from ecological archives preserved in sediments. Fossil diatom assemblages, reflective of past water quality, and other fossils, will be exhumed from sediment sequences to reconstruct wetland conditions. The integration of multiple indicators of the past will generate graphic re-enactments of natural wetland dynamics. These will provide a vision for community and government on-ground managers enabling them to perceive appropriate targets for wetland state and so generate measures to work towards sustainable conditions.Read moreRead less
