Resolving the classification and evolutionary history of the eucalypts. This collaborative project addresses the need to achieve a stable classification of the eucalypts, Australia's most ecologically and commercially important trees. The industry partners are lead agencies with responsibility for classification and identification of biodiversity, delivering taxonomic knowledge for end-users. Despite molecular studies in the last decade, the phylogenetic relationships of a number of the major ....Resolving the classification and evolutionary history of the eucalypts. This collaborative project addresses the need to achieve a stable classification of the eucalypts, Australia's most ecologically and commercially important trees. The industry partners are lead agencies with responsibility for classification and identification of biodiversity, delivering taxonomic knowledge for end-users. Despite molecular studies in the last decade, the phylogenetic relationships of a number of the major subgroups of the eucalypts are unknown. We will sequence new regions of DNA and combine this with morphological data to resolve the relationships of the eucalypt lineages, and hence their classification. Phylogenetic analysis also aids identification of high-value areas for conservation of relictual species.Read moreRead less

This collaboration with the Royal Botanic Gardens Melbourne will resolve the phylogeny of Australia's largest group of flowering plants, the acacias, to form the basis of a new classification. With more than 960 species, Australian acacias are a major biodiversity resource yet their genetic diversity and evolutionary relationships are poorly known. We will determine the main taxonomic gro ....Resolving the molecular phylogeny and classification of Australian acacias, a major biodiversity resource. This collaboration with the Royal Botanic Gardens Melbourne will resolve the phylogeny of Australia's largest group of flowering plants, the acacias, to form the basis of a new classification. With more than 960 species, Australian acacias are a major biodiversity resource yet their genetic diversity and evolutionary relationships are poorly known. We will determine the main taxonomic groups and their relationships by sequencing the DNA of more than 300 species. Acacias are of ecological importance and of use in land reclamation, horticulture, and rural craftwood industries.

Testing Theories of Historical Divergence using South Eastern Australian Reptiles. The processes that serve to create species diversity must also be preserved in order to allow evolution to continue. My study will clarify the number and distribution of water skink species in south eastern Australia, a biologically diverse, yet under studied area of Australia. I will also be looking at processes, such as dispersal, that determine patterns of species distribution over time. These lizards are also ....Testing Theories of Historical Divergence using South Eastern Australian Reptiles. The processes that serve to create species diversity must also be preserved in order to allow evolution to continue. My study will clarify the number and distribution of water skink species in south eastern Australia, a biologically diverse, yet under studied area of Australia. I will also be looking at processes, such as dispersal, that determine patterns of species distribution over time. These lizards are also found on mountain tops and may be affected by global warming. Understanding how climate change has affected these lizards in the past may help us to predict how climate changes will affect them in the future and better enable us to conserve these and other species in the future.Read moreRead less
Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from es ....Evolution of the unique fauna of the Great Artesian Basin mound springs: the impact of aridification and climate change. The mound springs of the Great Artesian Basin represent one of Australia's most unique environments and are of national biodiversity, cultural and economic significance. Their conservation is a major issue following listing of the springs as a threatened ecological community. As economic productivity in the GAB intensifies, the mound springs are under increasing threat from escalating groundwater use. The results of this study on the evolution of two crustacean groups will provide significant biological information for management plans, facilitating conservation of mound springs communities, and helping to understand the impacts of water extraction and climate change on this unique habitat.Read moreRead less

This project will use a comparative approach that combines ecological, morphological and molecular data to investigate evolutionary patterns of ecological specialisation in Australian agamid lizards. Understanding the evolutionary pattern of ecological specialisation, or the directional course of evolution, is an unresolved question in evolutionary biology. Quantitative investigations of ecological specialisation are rare because research has been limited by molecular and analytical techniques. Recent advances in population genetics and bio-statistics will allow me to test hypotheses concerning the directionality of evolution. This study will provide a foundation for future research in evolutionary biology and greatly expand our knowledge of agamid biodiversity.Read moreRead less
