Connectivity and movements of large pelagic species of ecotourism value. The project aims to answer key questions about the biology, ecology and sustainability of the world’s manta ray species to provide the information and tools for management and conservation of these charismatic and valuable species. In particular, the project aims to determine the likely impact of climate variability and fisheries that operate to Australia’s north on manta-based ecotourism in the Indo-Pacific region, as clim ....Connectivity and movements of large pelagic species of ecotourism value. The project aims to answer key questions about the biology, ecology and sustainability of the world’s manta ray species to provide the information and tools for management and conservation of these charismatic and valuable species. In particular, the project aims to determine the likely impact of climate variability and fisheries that operate to Australia’s north on manta-based ecotourism in the Indo-Pacific region, as climate change and active low-value fisheries may both jeopardise a high-value ecotourism industry. The project seeks to explore geographic distributions, local and large-scale movements, population sizes, structure, and inter-connectivity in the region to assess the effect of climate and fisheries on manta ray populations.Read moreRead less
Testing metabolic theories in ecology. There are striking similarities in the way plants and animals take up and use energy (metabolism), despite enormous variation in size and life-style. This project will make the first experimental comparison of the predictions of the two major theories for these broad patterns. The results will significantly progress this controversial and exciting field.
Understanding the ecological effects of genetic diversity: causes, consequences and relative importance. This project will examine the effect of genetic diversity on key demographic parameters (for example, population growth rates) for organisms from three groups, including a commercially important oyster. This project provides valuable information that can be used by managers of wild and cultivated populations to minimise impacts of human activities and maximise yields.
Horizontal ecological networks for understanding biodiversity maintenance. The project aims to develop new ecological theory on local diversity maintenance based on an innovative interaction network model, tested on Western Australian wildflower communities. It is novel in its focus on the complexity of species interactions and their importance to diversity maintenance in nature. This project aims to explore links between plant interaction networks and coexistence theory to provide theoretical e ....Horizontal ecological networks for understanding biodiversity maintenance. The project aims to develop new ecological theory on local diversity maintenance based on an innovative interaction network model, tested on Western Australian wildflower communities. It is novel in its focus on the complexity of species interactions and their importance to diversity maintenance in nature. This project aims to explore links between plant interaction networks and coexistence theory to provide theoretical expectations for how changes to the environment are expected to alter natural plant communities. It aims to fill theory-gap about mechanisms of multi-species coexistence, advance community ecology, and provide the theoretical foundations necessary for translating ecological theory to restoration and conservation in practice.Read moreRead less
How positive interactions improve predictions of plant community diversity. Though common in nature, the importance of plant-plant facilitation to coexistence and the maintenance of plant diversity at community scales is poorly understood. This project aims to advance understanding of how positive interactions (facilitation) impact on coexistence among plant species as well as local patterns of diversity. To achieve these aims the project will use a combination of field experiments and a compara ....How positive interactions improve predictions of plant community diversity. Though common in nature, the importance of plant-plant facilitation to coexistence and the maintenance of plant diversity at community scales is poorly understood. This project aims to advance understanding of how positive interactions (facilitation) impact on coexistence among plant species as well as local patterns of diversity. To achieve these aims the project will use a combination of field experiments and a comparative analysis of competition and facilitation in Australian, Californian and Spanish annual plant communities with a novel modelling approach for predicting coexistence across variable environments. Outcomes are expected to include an innovative predictive framework of use for plant conservation in Australia and beyond.Read moreRead less
Macroecology of reptiles and frogs over latitudinal and temporal gradients. This project aims to address major macroecological concepts in reptile and frog communities through time, focusing on environmental and climatic gradients in species diversity and body-size variation. This project expects to generate a unique macroecological dataset by integrating data from Quaternary fossil sites spanning a 3000km latitudinal gradient with current ecological data. Expected outcomes include the first com ....Macroecology of reptiles and frogs over latitudinal and temporal gradients. This project aims to address major macroecological concepts in reptile and frog communities through time, focusing on environmental and climatic gradients in species diversity and body-size variation. This project expects to generate a unique macroecological dataset by integrating data from Quaternary fossil sites spanning a 3000km latitudinal gradient with current ecological data. Expected outcomes include the first comprehensive ecological assessment of Australian reptile and frog communities through Pleistocene climate oscillations, with predictions into the future. This research will benefit Australian society by providing evidence-based knowledge of faunal community composition through time in association with changing climates.Read moreRead less
How does allocation to each sex evolve in hermaphrodites? New insight from the sea. Understanding the ability of hermaphroditic animals to adapt their sex allocation to suit environmental conditions will pave the way for integration between pure and applied research. Such understanding can provide stakeholders across a range of disciplines (natural resource management, aquaculture, conservation) with key information about genetic and environmental influences on the reproduction of many species o ....How does allocation to each sex evolve in hermaphrodites? New insight from the sea. Understanding the ability of hermaphroditic animals to adapt their sex allocation to suit environmental conditions will pave the way for integration between pure and applied research. Such understanding can provide stakeholders across a range of disciplines (natural resource management, aquaculture, conservation) with key information about genetic and environmental influences on the reproduction of many species of significant ecological, economic and social value with this mating system. This research will yield knowledge at the very forefront of evolutionary ecology, enhancing Australia's reputation for research excellence in this field, and further benefit Australian science through the training of young scientists.Read moreRead less
