Australia's monsoon tropical flora: invader or relict? The monsoonal tropics is a large region with unique yet poorly understood biodiversity. It is undergoing rapid agricultural, urban and tourist development, all of which threaten the sustainability of that biodiversity. The region includes three World Heritage areas, all with flora in their listed values: Kakadu National Park, Purnulu NP (Bungle Bungles) and Riversleigh. Additionally, the Kimberley is considered one of the last great wilderne ....Australia's monsoon tropical flora: invader or relict? The monsoonal tropics is a large region with unique yet poorly understood biodiversity. It is undergoing rapid agricultural, urban and tourist development, all of which threaten the sustainability of that biodiversity. The region includes three World Heritage areas, all with flora in their listed values: Kakadu National Park, Purnulu NP (Bungle Bungles) and Riversleigh. Additionally, the Kimberley is considered one of the last great wilderness areas in the world. This project will help us understand the evolutionary and geographic origins of the biodiversity of the monsoonal tropics, including the World Heritage areas, and it will identify those components that are uniquely Australian and therefore have the greatest heritage values.Read moreRead less
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.
The role of ecological specialisation in insect-plant macroevolutionary processes: a molecular phylogenetic approach across three kingdoms. Flowering plants and phytophagous insects are major components of the world's biodiversity and their evolution has been closely linked. This project will increase our knowledge of insect-endosymbiont-plant interactions and enhance our understanding of the origin, generation and maintenance of much of the world's biodiversity. A broader understanding of how i ....The role of ecological specialisation in insect-plant macroevolutionary processes: a molecular phylogenetic approach across three kingdoms. Flowering plants and phytophagous insects are major components of the world's biodiversity and their evolution has been closely linked. This project will increase our knowledge of insect-endosymbiont-plant interactions and enhance our understanding of the origin, generation and maintenance of much of the world's biodiversity. A broader understanding of how insects, their symbionts and plants have co-evolved should improve our understanding of why and how some insects are able to become pests whereas others do not. Scale insects (the model system in this study) are important pests, both ecologically (Christmas Island interaction between coccids, rainforest plants and crazy ants) and economically (e.g. citrus mealybug).Read moreRead less
Molecular Phylogenetics of Australian Myobatrachid Frogs and the Evolution of Reproductive Strategies. The Family Myobatrachidae (22 genera, 120+ species) is wholly endemic to the Australo-Papuan region, represents 57% of the Australian frog fauna and displays more diversity in reproductive strategies than any other group of frogs. We will recover a robust molecular phylogeny for all species in this family and use it to exploit existing ecological and behavioural data sets to provide powerful te ....Molecular Phylogenetics of Australian Myobatrachid Frogs and the Evolution of Reproductive Strategies. The Family Myobatrachidae (22 genera, 120+ species) is wholly endemic to the Australo-Papuan region, represents 57% of the Australian frog fauna and displays more diversity in reproductive strategies than any other group of frogs. We will recover a robust molecular phylogeny for all species in this family and use it to exploit existing ecological and behavioural data sets to provide powerful tests of alternative hypotheses concerning the evolution of diverse reproductive strategies. This multi-disciplinary research project will provide detailed phylogenetic information for one of the most diverse vertebrate radiations in Australia and address important questions in historical ecology.Read moreRead less
Analysing the roles of cospeciation and host-shifting in the evolution of behaviour and ecology of thrips associated with Australian Acacia. The relationships and interactions between phytophagous thrips and their host Acacia species provide a system well suited to investigating mechanisms of macroevolution in the Australian arid-zone biota. In this project we will determine the relative importance of mechanisms such as cospeciation and host-shifting within this model system, and examine the in ....Analysing the roles of cospeciation and host-shifting in the evolution of behaviour and ecology of thrips associated with Australian Acacia. The relationships and interactions between phytophagous thrips and their host Acacia species provide a system well suited to investigating mechanisms of macroevolution in the Australian arid-zone biota. In this project we will determine the relative importance of mechanisms such as cospeciation and host-shifting within this model system, and examine the influence of these mechanisms on the evolution of both the insects and the host-plants. It is expected that the results of this study will provide insights into the evolution of arid-zone biodiversity in Australia and the nature of insect/host-plant interactions.Read moreRead less
Reconstructing the impact of climate change on Australian native species. This project will explore the impact of past climate change on Australian native animals to identify species and ecosystems at greatest potential risk, and to help predict and minimise the effects of future change.
Landscape restoration genomics for climate adaptation in eucalyptus foundation species. Understanding the genetic basis of adaptation in foundation species will allow selection of pre-adapted seeds to establish resilient ecosystems which support the broad range of life supporting services. This project will apply genomics to solve real environmental challenges in restoration management and be a model for other foundation species.
Origins of a biodiversity hotspot flora: diversification of the Australian Proteaceae. Why does Australia's only biodiversity hotspot, with nearly 3000 endemic plant species, occur in an area with poor soils and low rainfall? This project will analyse DNA sequences from over 1000 plant species of the Australian Proteaceae, many found only in this hotspot, to help us understand the evolutionary and ecological origins of this iconic flora.
