Summary
High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of ....High throughput nitrogen analysis for ecological studies. Australian environments are unproductive partly because they contain little Nitrogen (N) and changes in atmospheric CO2 will exacerbate this. Furthermore, animals cannot extract all the N from the plants they eat. An assay has been developed that measures how much they can extract (available N) and it is intended to use it to measure habitat quality and the effects of climate change over large tracts of land. This requires thousands of N analyses. The equipment we are requesting - a LECO combustion analyser, allows us to analyse samples quickly and safely and uses fewer chemicals and much less water than do traditional machines.Read moreRead less

The results from this project will be a key reference when assessing future impacts of human-induced impacts on natural communities. Our research will provide insights into the impacts of climate change on herbivorous insects associated with Acacia: the dominant plant genus in the major climatic zones of Australia. Results and conclusions from this research will aid land-holders, government agencies and other parties in determining how important Acacia-dominated ecosystems are in conserving insect biodiversity in a range of different habitats within regional and rural Australia. Our research will also aid in a better understanding of biocontrol agents of Australian Acacia pest species here and overseas.Read moreRead less
Comparative phylogeography and patterns of diversification in Amazonian fishes. I anticipate that this project will increase the research profile of Australia in the international scientific community by answering fundamental questions about the origin of biodiversity in the world's most diverse ecosystem, the lowland forests of central Amazonia. This will be achieved by analysing what will be the most comprehensive phylogeographic data set ever generated for Amazonian organisms. The project wil ....Comparative phylogeography and patterns of diversification in Amazonian fishes. I anticipate that this project will increase the research profile of Australia in the international scientific community by answering fundamental questions about the origin of biodiversity in the world's most diverse ecosystem, the lowland forests of central Amazonia. This will be achieved by analysing what will be the most comprehensive phylogeographic data set ever generated for Amazonian organisms. The project will provide information for comparing with patterns seen in the Australian wet tropics and will be inspirational for studies on population diversification of Australian fishes.

Does adaptive plasticity play a significant role in the initial colonisation of novel habitats? An increased understanding of the evolutionary and ecological processes responsible for generating Australian biodiversity can facilitate effective management and conservation of this unique resource. Islands are especially significant in this context because they host many kinds of distinctive fauna and flora that have vanished from mainland habitats. It is therefore crucial to understand the biolo ....Does adaptive plasticity play a significant role in the initial colonisation of novel habitats? An increased understanding of the evolutionary and ecological processes responsible for generating Australian biodiversity can facilitate effective management and conservation of this unique resource. Islands are especially significant in this context because they host many kinds of distinctive fauna and flora that have vanished from mainland habitats. It is therefore crucial to understand the biology of these small isolated systems, as a way to preserve those unique systems as well as the distinctive evolutionary processes that occur within them.Read moreRead less
Phylogeography, Conservation Genetics and Stocking Management of Perches and Basses. This project will use DNA data to address fundamental questions about the origin and maintenance of biodiversity in a popular and widely distributed fish group. From a conservation perspective, the project will produce a benchmark about management of fish resources. We will investigate questions related to important conservation issues (including the recovery plan of a nationally threatened species) and the mana ....Phylogeography, Conservation Genetics and Stocking Management of Perches and Basses. This project will use DNA data to address fundamental questions about the origin and maintenance of biodiversity in a popular and widely distributed fish group. From a conservation perspective, the project will produce a benchmark about management of fish resources. We will investigate questions related to important conservation issues (including the recovery plan of a nationally threatened species) and the management of stocking activities in recreational fisheries of coastal and inland waters. The latter is particularly relevant to rural communities since they provide both social and economic benefits to rural people.Read moreRead less
Toad vs Toad: Innovative approaches to understand and control an invasive species. Understanding the ecology of an invasive pest species can be a powerful tool for developing control methods. Cane toads pose a major threat to Australian native species, and are spreading increasingly rapidly through the Australian tropics. Unfortunately, we still know very little about the biology of invasion-front populations of toads. This project will provide that understanding, and will explore new ideas a ....Toad vs Toad: Innovative approaches to understand and control an invasive species. Understanding the ecology of an invasive pest species can be a powerful tool for developing control methods. Cane toads pose a major threat to Australian native species, and are spreading increasingly rapidly through the Australian tropics. Unfortunately, we still know very little about the biology of invasion-front populations of toads. This project will provide that understanding, and will explore new ideas about ways to control toad populations. For example, if we can reduce the survival of feral animals by increasing the intensity of competition within their own popualtions rather than relying on effects of other species, we may be able to use the toads to control their own populations.Read moreRead less
Predicting the ecological impact of cane toads on native fauna of northwestern Australia. At current rates of spread, cane toads will invade the Kimberley region of northwestern Australia within a few years. We urgently need to be able to predict which native species will be at risk from toads, and which will be relatively unaffected either because they are not killed by toads, or because they can rapidly learn, or evolve, in ways that reduce this impact and thus allow population recovery. We ....Predicting the ecological impact of cane toads on native fauna of northwestern Australia. At current rates of spread, cane toads will invade the Kimberley region of northwestern Australia within a few years. We urgently need to be able to predict which native species will be at risk from toads, and which will be relatively unaffected either because they are not killed by toads, or because they can rapidly learn, or evolve, in ways that reduce this impact and thus allow population recovery. We will obtain these data by exposing native animals to toads and recording the results; and thus, can identify the most important priorities for conservation efforts.Read moreRead less
The roles of relatedness and reproductive success in complex social systems of dolphins. Theories of the role of genetic relatedness and reproductive success in mammalian social behaviour have mostly been restricted to primates and carnivores. Coexisting alternative strategies within one population of bottlenose dolphins (Shark Bay WA) offer unprecedented opportunities for such investigations. The male alliances? complexity is unparalleled outside humans, and may require new theory. Some femal ....The roles of relatedness and reproductive success in complex social systems of dolphins. Theories of the role of genetic relatedness and reproductive success in mammalian social behaviour have mostly been restricted to primates and carnivores. Coexisting alternative strategies within one population of bottlenose dolphins (Shark Bay WA) offer unprecedented opportunities for such investigations. The male alliances? complexity is unparalleled outside humans, and may require new theory. Some female lineages show tool-use - rare outside humans, and virtually unknown in marine species. Our behavioural and genetic database has exceptional size, detail and duration for marine mammals, and is most valuable if continued while known individuals' offspring reach a stage where they can be sampled.Read moreRead less
Mate choice near and far: Genetic compatibility, sexual selection, and speciation in Australian grass finches. The pressure on individuals to choose a genetically compatible partner has the capacity to drive the evolution of mating systems and the process of speciation, and is therefore a major engine of biodiversity. Reproductive failure resulting from incompatibility between individuals is more likely when individuals from fragmented and genetically structured populations mate with one another ....Mate choice near and far: Genetic compatibility, sexual selection, and speciation in Australian grass finches. The pressure on individuals to choose a genetically compatible partner has the capacity to drive the evolution of mating systems and the process of speciation, and is therefore a major engine of biodiversity. Reproductive failure resulting from incompatibility between individuals is more likely when individuals from fragmented and genetically structured populations mate with one another. This work will give new insight into biological processes that drive biodiversity and effect the management of threatened populations and endangered species. The proposed research will raise the international profile of Australian science and biodiversity and improve our ability to manage our natural biological resources. Read moreRead less
