Managing genetic diversity and evolutionary processes in foundation species for landscape restoration in the midwest of Western Australia. This project analyses genetic structure in four key plant species used for post mining restoration across the midwest. It will provide guidelines for seed collections that ensure planted populations will persist at altered sites after mining and that planted and natural populations can adapt to changing future environmental conditions.
The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to unde ....The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to understand the genetic potential of organisms to adapt to anthropomorphic change in the environment connected with the resources industry. Our work, will bring new insight into the future management of environmental contamination, and the mitigation of adverse effects arising from resource extraction.Read moreRead less
Islands of rocks: geckos as a model system to understand patterns of biodiversity, endemism and speciation in the Kimberley. Australia is renowned for its diversity of lizards, yet a plethora of new "cryptic" gecko species continue to be discovered. The project will densely sample the complex Kimberley to understand the evolution of its geckos, which will shed light on true levels of species diversity and the geological and environmental history of this biodiversity hotspot.
Evolution and biogeography of Australian idiopid trapdoor spiders: implications for conservation biology and environmental assessment. Trapdoor spiders (family Idiopidae) are poorly studied and there are many new species with restricted distributions in the western and arid parts of the continent. This project will use DNA techniques to study their evolution and provide genetic criteria for their identification, environmental assessment and determining conservation priorities.
Biodiversity and population genetics of groundwater calcrete ecosystems of central Western Australia. This project will lead to documentation of a unique subterranean ecosystem of world acclaim, representing a significant component of the biodiversity of the Australian arid zone. It will further contribute to sustainable management of groundwater ecosystems and provide information that can be used to predict and monitor how future water use and climate change may impact on these ecosystems. Resu ....Biodiversity and population genetics of groundwater calcrete ecosystems of central Western Australia. This project will lead to documentation of a unique subterranean ecosystem of world acclaim, representing a significant component of the biodiversity of the Australian arid zone. It will further contribute to sustainable management of groundwater ecosystems and provide information that can be used to predict and monitor how future water use and climate change may impact on these ecosystems. Results generated will provide the knowledge base required to improve the efficiency and scientific rigour of the environmental review process for major resource projects, leading to economic benefits to the mining and environmental consultancy industries, and to Australia in general.Read moreRead less
Assessment of the diversity, distribution and uniqueness of subterranean animals from calcrete aquifers in central western Australia. Recently a rich and diverse subterranean invertebrate fauna (stygofauna) was unexpectedly discovered from numerous isolated calcrete aquifers associated with palaeodrainage channels in central Western Australia. Our recent taxonomic and molecular studies have suggested that stygofaunas within each aquifer may be highly endemic. We aim to test this hypothesis by in ....Assessment of the diversity, distribution and uniqueness of subterranean animals from calcrete aquifers in central western Australia. Recently a rich and diverse subterranean invertebrate fauna (stygofauna) was unexpectedly discovered from numerous isolated calcrete aquifers associated with palaeodrainage channels in central Western Australia. Our recent taxonomic and molecular studies have suggested that stygofaunas within each aquifer may be highly endemic. We aim to test this hypothesis by investigating the diversity, distribution and uniqueness of stygofauna from three major calcrete regions. We further aim to document the environmental conditions and variability within the aquifers and to develop rigorous sampling protocols. Such data are essential for the development of appropriate strategies for sustainable management of subterranean water and their ecosystems.Read moreRead less
Environmental stress profiling (ESP): Molecular profiling of sediment microbial communities for improved biological monitoring in aquatic ecosystems. Water resource management is a key issue for environmental sustainability in Australia and strategies that include ecological principles are important to improve present conditions and reduce further degradation. Current biomonitoring methods suffer from a low degree of sensitivity that can seriously impact their effectiveness as early warning sign ....Environmental stress profiling (ESP): Molecular profiling of sediment microbial communities for improved biological monitoring in aquatic ecosystems. Water resource management is a key issue for environmental sustainability in Australia and strategies that include ecological principles are important to improve present conditions and reduce further degradation. Current biomonitoring methods suffer from a low degree of sensitivity that can seriously impact their effectiveness as early warning signals of ecological disturbance. We propose to combine molecular and ecotoxicological assessment of the effect of zinc toxicity on microbial communities to provide rapid pollution sensitive bioassessment. Our research will lead to a better understanding of the cause and effect of heavy metal pollution within aquatic ecosystems and greater insight on how to reduce and repair the negative effects.Read moreRead less
The ecology of parasite transmission in fauna translocations. Parasitic diseases pose a threat to the conservation management of Australia's biodiversity. This project will improve our understanding of the impact and transmission of parasites in fauna translocations, contributing to the conservation management of Australian ecosystems by government and private agencies.
Evolution of Australia's globally unique hotspot of floral diversity. Australia has a globally recognised biodiversity hotspot, the southwest of Western Australia, but this unique eucalypt-dominated flora is threatened. This project will gain new insights into the evolutionary processes that generate and maintain such diversity, their vulnerability; and how the iconic eucalypts came to dominate the Australian landscape.
