Larval Dispersal And The Design Of Marine Reserve Networks: Benefits Within And Beyond Boundaries. Most marine organisms produce tiny offspring that are dispersed unknown distances by oceanic currents. Our present strategies to manage marine resources lack this vital piece of information. This study will apply two revolutionary techniques that finally enable us to determine how far marine larvae travel. Using the team that developed these techniques, field studies will for the first time measure ....Larval Dispersal And The Design Of Marine Reserve Networks: Benefits Within And Beyond Boundaries. Most marine organisms produce tiny offspring that are dispersed unknown distances by oceanic currents. Our present strategies to manage marine resources lack this vital piece of information. This study will apply two revolutionary techniques that finally enable us to determine how far marine larvae travel. Using the team that developed these techniques, field studies will for the first time measure both retention of fish larvae within marine protected areas and dispersal of larvae to adjacent fished areas on coral reefs. This information can be directly applied to optimize the size of reserves and their spacing in marine protected area networks.Read moreRead less
Managing the evolutionary potential of fragmented native plant populations. Many previously widespread plant species now exist in small fragmented populations threatened with extinction due to genetic decline. We will apply a novel and powerful new genetic approach for the assessment of the evolutionary potential of these populations. Through the most detailed characterisation of realized mating yet possible, we will determine if recently fragmented populations are in genetic decline, and how ....Managing the evolutionary potential of fragmented native plant populations. Many previously widespread plant species now exist in small fragmented populations threatened with extinction due to genetic decline. We will apply a novel and powerful new genetic approach for the assessment of the evolutionary potential of these populations. Through the most detailed characterisation of realized mating yet possible, we will determine if recently fragmented populations are in genetic decline, and how anciently fragmented species avoid extinction. Our aim is to generate general principles for the early measurement and/or prediction of genetic decline in species most at risk, that will enable us to determine how and when remediation measures are required.Read moreRead less
Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the ....Minimum sizes and habitat areas for viable populations. This project will address two critical issues in conservation biology: How large do wildlife populations need to be to ensure long-term persistence? How large an area needs to be preserved? At present, no such estimates exist for most species. I will develop realistic population viability analysis (PVA) models (encompassing all threats to persistence) on many bird, mammal, reptile, amphibian, invertebrate and plant species, and estimate the minimum population sizes and habitat areas required for long-term survival. My prior research has validated the predictive accuracy of PVA. This research will deliver practical guidelines for managing threatened species.Read moreRead less

A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertis ....A multidisciplinary research program to assess limiting factors and predict impacts of climate change for endangered Australian orchids. Climate change poses a significant threat to biodiversity. Australian sexually deceptive orchids are dependent on obligate and specialised interactions with pollinators and fungi. Consequently, they may face a high risk of extinction if climate change uncouples these interactions. Thus orchids provide an important bio-indicator of change. The tools and expertise developed will contribute directly to the conservation of endangered Australian orchids, and will take into account the risks of climate change. The project will contribute to the priority research goals of sustainable use of Australia's biodiversity as well as responding to climate change and variability. The project will also provide high quality, cross-disciplinary training.Read moreRead less
Rapid genetic delineation of local provenance for effective restoration of urban bushland remnants. Urban bushland remnants are a significant national resource. The rehabilitation of these remnants is a major enterprise drawing on national, state and local resources and substantial community involvement. Best practise recognises that material sourced from the local provenance is critical. Despite this, accurate guidelines on provenance are lacking. We will utilise powerful molecular markers to r ....Rapid genetic delineation of local provenance for effective restoration of urban bushland remnants. Urban bushland remnants are a significant national resource. The rehabilitation of these remnants is a major enterprise drawing on national, state and local resources and substantial community involvement. Best practise recognises that material sourced from the local provenance is critical. Despite this, accurate guidelines on provenance are lacking. We will utilise powerful molecular markers to rapidly generate provenance guidelines for priority species of the Swan coastal plain. We will work closely with restoration practitioners to ensure practical outcomes through adaptive management. Our objective is to generate a provenance atlas for the native plant restoration industry, with benefits flowing nationally.Read moreRead less

The rehabilitation of Australia's unique plant diversity, following disturbance, is an increasingly important activity nationally, involving industry, government and community. The use of local seeds is recognised as best practise, but how local is local? We will use molecular tools to identify the extent of local seed transfer zones, conduct trials to assess the relative performance of local and non-local seeds (is there a home-site advantage?), and assess the consequences of mixing provenances for future generations. We will work closely with industry and community restoration practitioners to improve the effectiveness of restoration, with benefits flowing nationally through general provenance guidelines.Read moreRead less
