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

Summary
The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit in ....The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit includes the reduction of total grazing pressure on pastures and native vegetation of Kangaroo Island, which is one of Australia’s top 15 biodiversity ‘hot spots’, and thus help with conservation efforts on Kangaroo Island. Economic benefit will follow if farmers receive income from a currently wasted resource.Read moreRead less
Ecology and conservation of a unique, threatened guanophilic invertebrate community. This project aims to study the biology and ecology of a unique assemblage of insects and other invertebrates that live specifically in bat guano at Naracoorte Caves World Heritage Area. The caves are a major ecotourism and research location because of their world famous Pliestocene fossils, and because one cave is a critical breeding site for the large bentwing bat, Miniopterus s. bassianii. The guano cave, whic ....Ecology and conservation of a unique, threatened guanophilic invertebrate community. This project aims to study the biology and ecology of a unique assemblage of insects and other invertebrates that live specifically in bat guano at Naracoorte Caves World Heritage Area. The caves are a major ecotourism and research location because of their world famous Pliestocene fossils, and because one cave is a critical breeding site for the large bentwing bat, Miniopterus s. bassianii. The guano cave, which contains numerous endemic invertebrates, is potentially threatened by both direct and indirect human impacts. The results of this research will form the basis of a long-term management strategy to conserve this diverse community.Read moreRead less
Climate change and phenotypic divergence at a landscape scale. Birds provide key ecosystem functions like pollination, insect control, and seed dispersal in Australia. Climate change is well documented and has a pronounced effect on birds, commonly leading to range shifts. This study will quantify patterns of gene flow at a landscape scale in declining and common birds in Australia and abroad. The project builds on strong international links to the Galapagos Islands as well as a regional focus f ....Climate change and phenotypic divergence at a landscape scale. Birds provide key ecosystem functions like pollination, insect control, and seed dispersal in Australia. Climate change is well documented and has a pronounced effect on birds, commonly leading to range shifts. This study will quantify patterns of gene flow at a landscape scale in declining and common birds in Australia and abroad. The project builds on strong international links to the Galapagos Islands as well as a regional focus for South Australia. The linkage organisations are committed to implementing management outcomes for native flora and fauna, which need to be underpinned with quality baseline data. The outcomes will also inform climate modelling for the State and Australia. Read moreRead less
The role of pulsed water events in structuring marine benthic communities along the southern Australian coastline. Marked differences in benthic community structure have been observed that are associated with pulsed cold-water events, possibly driven by internal wave phenomena. Such events have the potential to act as very important controls on both regional and local patterns of benthic biodiversity. To date, however, their effects and mechanisms of action have never been examined in Australi ....The role of pulsed water events in structuring marine benthic communities along the southern Australian coastline. Marked differences in benthic community structure have been observed that are associated with pulsed cold-water events, possibly driven by internal wave phenomena. Such events have the potential to act as very important controls on both regional and local patterns of benthic biodiversity. To date, however, their effects and mechanisms of action have never been examined in Australia. The fundamental outcome from this project will be the first assessment of the occurrence, geographical extent and ecological consequences of pulsed water phenomena along the southern Australian coastline.Read moreRead less
Population genetics and dynamics of orchids and their pollinators in fragmented landscapes of South Australia. Many species of orchids in fragmented landscapes need active management to secure their persistence. The effects of fragmentation can be direct (e.g. reduction in population sizes, environmental quality, increased inbreeding, reduced dispersal ability), or indirect through negative effects on pollinators. Little information exists on the complex interactions between effects of fragmenta ....Population genetics and dynamics of orchids and their pollinators in fragmented landscapes of South Australia. Many species of orchids in fragmented landscapes need active management to secure their persistence. The effects of fragmentation can be direct (e.g. reduction in population sizes, environmental quality, increased inbreeding, reduced dispersal ability), or indirect through negative effects on pollinators. Little information exists on the complex interactions between effects of fragmentation on plants and their pollinators. This project aims to understand how fragmentation affects the genetic diversity and demography of selected populations of orchids and their pollinators in the Mt.Lofty/Flerieu Peninsula area. This information will help to develop and implement more effective conservation plans.Read moreRead less

Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that clim ....Responses of southern Australian mammal faunas to climate change before and after human arrival. In the past 170 years, southern Australia mammals have suffered one of the worst extinction rates in the world. More losses are predicted in the face of global warming. This recent extinction wave follows a major extinction event that saw 90% of Australia's large animals disappear 60,000-40,000 years ago. The causes are hotly debated. Some researchers argue for a human cause, others suggest that climate change was to blame. This study will refine our knowledge of the timing and causes of these extinctions in southern Australia by assessing how communities responded to climate change in the lead-up to human arrival. It will provide vital information for managing the conservation of many modern species and guide us in limiting future losses.Read moreRead less
Landscape-scale monitoring and adaptive management of woodland birds in the Mt Lofty Ranges. Despite the fundamental role of scientific monitoring in nature conservation, its research importance and potential is widely neglected. There is an urgent need to improve quantitative rigour, particularly to ensure adequate statistical power is achieved when monitoring at a landscape scale. We will apply new analytical tools to the problem of devising a powerful and flexible monitoring regime for a high ....Landscape-scale monitoring and adaptive management of woodland birds in the Mt Lofty Ranges. Despite the fundamental role of scientific monitoring in nature conservation, its research importance and potential is widely neglected. There is an urgent need to improve quantitative rigour, particularly to ensure adequate statistical power is achieved when monitoring at a landscape scale. We will apply new analytical tools to the problem of devising a powerful and flexible monitoring regime for a highly threatened woodland bird community in South Australia. Monitoring will be embedded within a decision-making framework with explicit links to local management agencies. Results will be broadly applicable across agricultural areas of Australia, where bird assemblages are in general decline.Read moreRead less
Applying macroecology to assist in the management of Kakadu National Park. The ecological integrity of Kakadu National Park is threatened by fires, weeds, and feral animals. To help tackle these problems, we will develop a cost-effective, culturally appropriate, park-wide monitoring system based on changes in the boundaries of closed forests, woodland and grassland. We will gauge the effect of broad-scale land management interventions, and predict the consequences of future change. The findings ....Applying macroecology to assist in the management of Kakadu National Park. The ecological integrity of Kakadu National Park is threatened by fires, weeds, and feral animals. To help tackle these problems, we will develop a cost-effective, culturally appropriate, park-wide monitoring system based on changes in the boundaries of closed forests, woodland and grassland. We will gauge the effect of broad-scale land management interventions, and predict the consequences of future change. The findings of this study will be transferable to other landscape settings in Australia and overseas. It will contribute to debates about the ecological consequences of current land management practices and how these compare with past Aboriginal land management.Read moreRead less
