Understanding and reversing the habitat shifts that have endangered the broad-headed snake. Extinction rates for vertebrate species are higher in southern Australia than almost anywhere else in the world, and saving endangered taxa is critical to biodiversity conservation. To do this effectively, researchers need to understand the processes that threaten wild populations, and to develop novel solutions to those problems in close collaboration with wildlife management authorities and other stake ....Understanding and reversing the habitat shifts that have endangered the broad-headed snake. Extinction rates for vertebrate species are higher in southern Australia than almost anywhere else in the world, and saving endangered taxa is critical to biodiversity conservation. To do this effectively, researchers need to understand the processes that threaten wild populations, and to develop novel solutions to those problems in close collaboration with wildlife management authorities and other stakeholders. This project will build such an understanding and collaboration, focusing on an endangered snake species. We propose ambitious landscape-scale field experiments that will simultaneously test hypotheses on threatening processes, and restore habitat quality to reverse population declines.Read moreRead less

There will be diverse benefits from our testing and improvement of genetic indicators for exchange between populations and adaptive differentiation of populations. Managers and population biologists will have confidence in choice and use of these vital tools in sustainable use of our terrestrial and aquatic bioresources, as recommended by the federal State of Environment system. Also, the use of these tools to identify differential genetic adaptations is the first step in bioprospecting, as well as revealing the raw material for natural and artificial populations to adapt to changes: soil loss, salinity, acidity, climate change. Forensic genetics will benefit from the improved tools for defining subpopulations.Read moreRead less
Is recruitment of marine invertebrates affected by variation in larval quality? Managing marine populations and habitats requires detailed understanding of how populations are replenished, and why some places receive more new recruits than others. Attempts to reach this understanding have been hindered by the difficulty in studying tiny larvae that live in the plankton, and for most species, recruitment is a highly variable, unexplained phenomenon. We have identified a new explanation for this ....Is recruitment of marine invertebrates affected by variation in larval quality? Managing marine populations and habitats requires detailed understanding of how populations are replenished, and why some places receive more new recruits than others. Attempts to reach this understanding have been hindered by the difficulty in studying tiny larvae that live in the plankton, and for most species, recruitment is a highly variable, unexplained phenomenon. We have identified a new explanation for this variation, and will test this explanation using a marine invertebrate that is one of Australia's marine pests. A positive result offers promise of explaining recruitment variation in other species, and will provide insight into what makes this particular pest species successful.Read moreRead less
When corals bleach, what is the weakest photosynthetic link? Despite dire warning of the imminent impact (< 50 y) of climate change of coral reefs, we still do not understand the fundamental processes of coral bleaching. This project will enhance future management of Australia's extensive coral reef ecosystems by providing details on critical gaps in our knowledge. This will feed directly into several layers of management agencies for policy development and risk assessment. Managing our reefs in ....When corals bleach, what is the weakest photosynthetic link?

Dispersal and gene flow in habitat-forming algae. The temperate coast of Australia has a unique and diverse algal flora. Many of these algae play a central role in subtidal ecology by providing habitat to an astonishing diversity of taxa. Despite this, we have no understanding of levels of gene flow within and among populations of habitat forming algae or how such populations persist in nature. By addressing this lack of knowledge, my research will contribute information that is critical for the ....Dispersal and gene flow in habitat-forming algae. The temperate coast of Australia has a unique and diverse algal flora. Many of these algae play a central role in subtidal ecology by providing habitat to an astonishing diversity of taxa. Despite this, we have no understanding of levels of gene flow within and among populations of habitat forming algae or how such populations persist in nature. By addressing this lack of knowledge, my research will contribute information that is critical for the conservation and management of algal habitats. This is particularly pertinent because anthropogentic stressors are beginning to precipitate significant changes in algal forests along Australia's coastline. Read moreRead less
Does mate choice play a role in the fertilization ecology of free-spawners? Botanists have long recognised the consequences of differential compatibility between mates for breeding programs and agriculture. In important aquaculture species such as abalone and sea-urchins, similar variation in mate compatibility has been observed but current theory struggles to explain this variation and its consequences. I have identified a new explanation for this variation and will test this explanation using ....Does mate choice play a role in the fertilization ecology of free-spawners? Botanists have long recognised the consequences of differential compatibility between mates for breeding programs and agriculture. In important aquaculture species such as abalone and sea-urchins, similar variation in mate compatibility has been observed but current theory struggles to explain this variation and its consequences. I have identified a new explanation for this variation and will test this explanation using a marine invertebrate that is a model system for study around the world. A positive result offers promise of explaining how females 'select' mates in free-spawning species and explaining the consequence of this mate selection.Read moreRead less
