The danger within: assessing the threats to an endangered finch from genetic incompatibility, limited dispersal and effective population size. The Gouldian finch has declined dramatically over the past half century and remains one of Australia's most threatened birds. This project will use some cutting edge genetic techniques to understand some of the processes that undermine the species' recovery and our ability to monitor current populations.
Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify h ....Escalating the arms race: Understanding when and how trees get really tall. Australia's giant Eucalypt trees are an amazing phenomenon and resource; underpinning unique ecosystems, rich in timber, stored carbon, and animal habitat. While tree height generally arises via an evolutionary arms race for light, the race has escalated dramatically in some locations and species. Using a computational framework that simulates adaptation driven by size-structured competition, this project will quantify how distinct factors-including climate, recruitment, and disturbance-enhance the race for light and can thereby explain the origins of Australia's giant Eucalypt. With calibrated models of species evolution, coupled with targeted fieldwork and big data, this project clarifies key forces shaping present and future vegetation.Read moreRead less
Reproductive plasticity and climate change: insights from an opportunistic breeder. Across the globe, birds are struggling to optimise their reproductive timing and investment in a changing and unpredictable climate. This project will use the highly adaptable and opportunistic Australian zebra finch to develop an understanding of how birds tailor their behaviour and physiology to breed across a range of conditions.
Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional en ....Biotic connectivity within the temperate Australian marine protected area network at three levels of biodiversity, communities, populations and genes. Project outcomes will improve management of coastal biodiversity through a multi-state collaboration of managers, marine ecologists, population geneticists and taxonomists. Sites most needed within marine protected area (MPA) networks for maintaining resilience of populations across seascapes will be identified, including sites with exceptional endemism or key roles in dispersal of larvae. The ecological efficacy of the temperate Australian MPA network will be assessed through analysis of long-term ecological datasets and further development of a novel 'remote sensing' methodology, whereby surveys are undertaken by volunteer divers across much greater spatial and temporal scales than could be studied by dedicated scientific dive teams.Read moreRead less
