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.
How are visual gene pathways lost and restored during reptile evolution? This project aims to investigate how complex traits are lost during evolution, and once lost if they can be regained. The project will use the diverse visual systems of snakes and lizards to shed light on the process of gene loss in degenerative lineages, and discover the mechanisms that compensate for gene losses in taxa with secondarily evolved visual capabilities- providing a case of evolutionary re-innovation in complex ....How are visual gene pathways lost and restored during reptile evolution?

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
Evolution in tooth and claw: exploring the relationship between the radiation of marsupial herbivores and late Cenozoic climate change. Establishing how animals responded to past environmental changes is essential for understanding the ecology of modern species and managing them in light of contemporary climatic trends. By applying several novel analytical methods this project will unravel the links between the radiation of Australian marsupials and key stages in climatic evolution.
Faunal responses to environmental change and isolation on an Australian land-bridge island. Establishing how faunas responded to past isolation and environmental changes offers great potential for predicting long-term impacts of habitat fragmentation. By combining novel methods we will track extinction rates, diet and body-size shifts on Kangaroo Island, the only known land-bridge island with a fossil record spanning the past 100,000 years.
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.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.
Phylogenomic assessment of conservation priorities in two biodiversity hotspots: the Pilbara and the Kimberley. This project applies new sequencing and analytical methods to measure how much unique genetic diversity is represented in current and planned reserves across two biodiversity hotspots – the Pilbara and Kimberley of north-west Australia. It combines university, museum and conservation agency researchers to improve ongoing conservation planning.
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
