A molecular ecophysiological assessment of the importance of using local provenance seed in plant biodiversity restoration. 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 ....A molecular ecophysiological assessment of the importance of using local provenance seed in plant biodiversity restoration. 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
Conservation Management of the Endangered Pygmy Bluetongue Lizard. The Pygmy Bluetongue Lizard probably occurred over 150km of the Adelaide Plains before European settlement, but is now known from only a few privately owned properties in the mid-north of South Australia. Before adopting specific conservation strategies, such as release to new sites, more needs to be known about the genetic and social structure of viable populations, and the natural parasite fauna that may detrimentally affect an ....Conservation Management of the Endangered Pygmy Bluetongue Lizard. The Pygmy Bluetongue Lizard probably occurred over 150km of the Adelaide Plains before European settlement, but is now known from only a few privately owned properties in the mid-north of South Australia. Before adopting specific conservation strategies, such as release to new sites, more needs to be known about the genetic and social structure of viable populations, and the natural parasite fauna that may detrimentally affect any transplants. This project explores those aspects of the lizard biology, enhancing both our general understanding of lizard population structure and our specific understanding of conservation issues for this species.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

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

This information is currently unattainable but is indispensable for the lasting security of this culturally and ecologically significant mammal.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
Inbreeding and Amphibian Decline: from an Individual to a Global Perspective. Amphibian decline is not a phenomenon unique to overseas continents and countries. In the long line of research papers addressing this issue in the best science journals (e.g., Nature and Science), Australian frog decline has even been singled out for specific coverage. This project targets the interplay between habitat fragmentation, loss of genetic variation (inbreeding), and its effects on UV and pathogen resistance ....Inbreeding and Amphibian Decline: from an Individual to a Global Perspective. Amphibian decline is not a phenomenon unique to overseas continents and countries. In the long line of research papers addressing this issue in the best science journals (e.g., Nature and Science), Australian frog decline has even been singled out for specific coverage. This project targets the interplay between habitat fragmentation, loss of genetic variation (inbreeding), and its effects on UV and pathogen resistance in a laboratory model system. It integrates three disciplines (immunobiology, evolutionary genetics, and conservation biology) to resolve fundamental aspects of the drastic, ongoing disappearance of the most significant ecological indicator taxa known today (amphibians).
