Better water management through more focus on ecological and social sciences. Current water resources management, focusing on gains of economic efficiency in the short term under the assumption of steady-state conditions, has generally failed to respond to both catchment environmental degradation and to the increasing complexity of human–environment interactions. This project will develop a new approach to water resources management by relating management practices based on ecological understand ....Better water management through more focus on ecological and social sciences. Current water resources management, focusing on gains of economic efficiency in the short term under the assumption of steady-state conditions, has generally failed to respond to both catchment environmental degradation and to the increasing complexity of human–environment interactions. This project will develop a new approach to water resources management by relating management practices based on ecological understanding to the social mechanisms behind these practices at water catchments. It will improve the predictability and precision of water resources management and increase our ability to maintain our options for a sustainable future. This will have a profound effect on catchment sustainability, a globally significant problem.Read moreRead less
Beyond discrete landscape metrics: spatial analysis tools and surface textural measures for quantifying gradients in landscape structure. The project will make an important contribution to an Environmental Sustainable Australia, especially the sustainable use and management of Australia's biodiversity. The focus is Australia's biodiversity hotspots in northern Australia, where fauna species are threatened as a result of habitat modification and biological invasions.

The project will make an important contribution to an Environmental Sustainable Australia, especially the sustainable use and management of Australia's biodiversity. The focus is Australia's biodiversity hotspots in northern Australia, where fauna species are threatened as a result of habitat modification and biological invasions. The landscape analysis tools and supporting knowledge will allow for more effective landscape-level conservation strategies to be developed in northern regions by assisting researchers and managers to answer key questions about how to manage the structure of native vegetation for the long-term conservation of fauna populations. The project will also deliver benefits for conserving marine biodiversity. Read moreRead less
Predicting metapopulation dynamics with multiple patch states. Classical theory allows metapopulations to have subpopulations in one of two states, occupied or unoccupied. However, patches may have their own dynamic created by ecological succession or disturbance processes such as grazing. We will develop new theory incorporating patch dynamics, and test the theory on a spatially explicit metapopulation in the real world, the mound spring invertebrates of the Great Artesian Basin. We will use th ....Predicting metapopulation dynamics with multiple patch states. Classical theory allows metapopulations to have subpopulations in one of two states, occupied or unoccupied. However, patches may have their own dynamic created by ecological succession or disturbance processes such as grazing. We will develop new theory incorporating patch dynamics, and test the theory on a spatially explicit metapopulation in the real world, the mound spring invertebrates of the Great Artesian Basin. We will use the theory to forecast the risk of extinction for these endemic species, and develop methods to quantify the statistical power of monitoring for environmental trends.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
Landscape level effects on dispersal behaviour and gene flow in the logrunner, a rainforest restricted bird. Dispersal is thought to be critical for the persistence of small avian populations in fragmented landscapes. However, our knowledge of dispersal is limited. I will combine behavioural observations on radiotagged birds and powerful genetic markers to examine the effects of habitat fragmentation on the dispersal behaviour of a rainforest restricted bird, the logrunner. This study will deter ....Landscape level effects on dispersal behaviour and gene flow in the logrunner, a rainforest restricted bird. Dispersal is thought to be critical for the persistence of small avian populations in fragmented landscapes. However, our knowledge of dispersal is limited. I will combine behavioural observations on radiotagged birds and powerful genetic markers to examine the effects of habitat fragmentation on the dispersal behaviour of a rainforest restricted bird, the logrunner. This study will determine how landscape structure influences the movement of juvenile logrunners, investigate the causes and consequences of variation in juvenile dispersal behaviour, and use molecular data to determine how connectivity between habitats effects the genetic structure of logrunner populations.Read moreRead less
The conservation of widely distributed species: implications of differences between western and eastern koala populations. Koalas are an iconic species in Australia, generating $2.5 billion in tourist income alone. This project will be a first to test cross-regional variations in koala-habitat relationships, with implications for conservation of other species occupying broad geographical ranges. It will also predict the effect of future climate change on western koala populations living at the ....The conservation of widely distributed species: implications of differences between western and eastern koala populations. Koalas are an iconic species in Australia, generating $2.5 billion in tourist income alone. This project will be a first to test cross-regional variations in koala-habitat relationships, with implications for conservation of other species occupying broad geographical ranges. It will also predict the effect of future climate change on western koala populations living at the margin of their ecological tolerances. It will provide regional natural resource management bodies and state conservation agencies with a sound ecological framework to conserve western koalas in the long term. Regional communities will benefit from involvement by incorporating new conservation knowledge into sub-catchment and property management planning.Read moreRead less
A Bayesian framework for metapopulation dynamics of species in endangered communities: integrating demographic, environmental and genetic data. Biodiversity conservation is a spatial and temporal problem. Populations change in time, constrained by the structure and spatial division of their habitat. This study will develop a tool that can be used to assess the influence of environmental fluctuations and landscape heterogeneity on the persistence of endemic species in the mound springs of the Gr ....A Bayesian framework for metapopulation dynamics of species in endangered communities: integrating demographic, environmental and genetic data. Biodiversity conservation is a spatial and temporal problem. Populations change in time, constrained by the structure and spatial division of their habitat. This study will develop a tool that can be used to assess the influence of environmental fluctuations and landscape heterogeneity on the persistence of endemic species in the mound springs of the Great Artesian Basin. Using a Bayesian framework to integrate data from diverse sources, we will develop models for the biodiversity impacts of groundwater withdrawal and climate change in central Australia. These tools are essential for management of this ecosystem, which has been listed as an 'endangered community' under the Environmental Protection and Biodiversity Conservation Act of 1999.Read moreRead less
