Research outcomes from this new facility will empower government bodies, resource industries, and indigenous stakeholders with key baseline information to ensure the sustainable and sensitive development of west Australia's unique coastal and offshore regions, across heavily populated and pristine environments. This includes projecting future impacts on local industries (eg. energy, fisheries, tourism), rising shorelines with critical implications for existing and developing communities, and enhancing the resilience of habitats at risk. These are crucial to mitigate the impacts from environmental change that could severely affect our regional and national economies, as well as the style and quality of life of current and future generations.Read moreRead less
Symbiosomes and symbiosome membranes of corals and other cnidaria. Reef building corals and many other marine animals depend on symbiotic algae. Very little is known about the ways in which these organisms achieve effective communication with their endosymbionts, yet this is vital for understanding coral bleaching, a major present-day problem. In corals and their relatives, algae are housed in membrane-bounded vesicles, symbiosomes, which mediate the signal regulation that maintains an ongoin ....Symbiosomes and symbiosome membranes of corals and other cnidaria. Reef building corals and many other marine animals depend on symbiotic algae. Very little is known about the ways in which these organisms achieve effective communication with their endosymbionts, yet this is vital for understanding coral bleaching, a major present-day problem. In corals and their relatives, algae are housed in membrane-bounded vesicles, symbiosomes, which mediate the signal regulation that maintains an ongoing and healthy association at the cellular level. Unlike some terrestrial symbioses, little is known about the structure and function of the coral symbiosome. This study sets out to investigate this membrane at the cellular and molecular level.Read moreRead less
Population structure in the giant Australian cuttlefish - implications for management of a unique eco-tourism and fishery resource in regional Australia. A management strategy for the giant Australian cuttlefish in regional South Australia is required urgently because of potential conflict between ecotourism and fishery sectors. At present, development of a management strategy is stymied by lack of information on stock structure and movements. Analyses of variation in gene frequencies, morphom ....Population structure in the giant Australian cuttlefish - implications for management of a unique eco-tourism and fishery resource in regional Australia. A management strategy for the giant Australian cuttlefish in regional South Australia is required urgently because of potential conflict between ecotourism and fishery sectors. At present, development of a management strategy is stymied by lack of information on stock structure and movements. Analyses of variation in gene frequencies, morphometric and chemical trace element profiles in calcified structures among locations and years will enable the geographic extent of populations or stocks to be determined, including whether natal homing occurs. Such information is critical to sustainable management of the species and design of a marine protected area in the upper Spencer Gulf.Read moreRead less
How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I prop ....How connected are marine populations? Comparing life histories of endemic and non-endemic reef fishes to investigate the mechanisms behind self-recruitment. Recruitment of pelagic larvae plays a fundamental role in benthic marine populations, yet the sources and destinations of recruits are unknown for nearly all marine species. Because endemic species rely on retention of locally spawned larvae, they provide a novel opportunity for investigating the mechanisms allowing self-recruitment. I propose to compare the life histories and microchemical signatures in larval otoliths of endemic and closely related non-endemic reef fishes to determine the mechanisms and prevalence of self-recruitment. The results will broaden our understanding of how marine populations are replenished, information critically needed for marine conservation and resource management.Read moreRead less
Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the deve ....Network structure, connectivity and wildlife disease. Emerging infectious diseases of wildlife pose threats to human health (75% of human emerging diseases are zoonotic). They also threaten biodiversity and livestock. Changes in connectivity between wildlife individuals and populations are occurring because of human activities, including globalisation, climate change and habitat destruction. Understanding how these changes in connectivity affect wildlife disease dynamics is crucial for the development of better strategies to manage their impacts. The project will also build Australia's wider capacity to manage outbreaks of infectious diseases.Read moreRead less

This project responds to a national research priority by developing new methodology that will assist with the management and protection marine and terrestrial biodiversity in Australia and worldwide. It aligns with the requirements of the Australian community and our industry partners by contributing to plans for the long-term use of ecosystem goods and services, ranging from fisheries to ecotourism. The outcomes will provide data on dugong movements between protected areas on the eastern Australian coast. This information is currently unattainable but is indispensable for the lasting security of this culturally and ecologically significant mammal.Read moreRead less
Ontogeny of Behaviour and Sensory Abilities in Larvae of Marine Fishes. This project examines development of swimming performance, other behaviours and sensory abilities relevant to dispersal in larvae of a variety of marine fish species. Both laboratory and field methods will provide an overview of larval behaviour and sensory abilities throughout ontogeny. The extent to which morphological development explains these developmental differences in behaviour and sensory ability will be examined ....Ontogeny of Behaviour and Sensory Abilities in Larvae of Marine Fishes. This project examines development of swimming performance, other behaviours and sensory abilities relevant to dispersal in larvae of a variety of marine fish species. Both laboratory and field methods will provide an overview of larval behaviour and sensory abilities throughout ontogeny. The extent to which morphological development explains these developmental differences in behaviour and sensory ability will be examined in reared and wild individuals. This will provide direct evidence of when during the larval phase that fishes are able to actively modify dispersal patterns. This is important information for management of marine living resources and design of marine reserves.Read moreRead less
Setting the limits: Ecological and genetic tests of the status of marine populations at species borders. The wide dispersion of Australia's population along our coastal fringe combined with global climate change poses severe threats to marine biodiversity and necessitates urgent conservation measures. Our study will use ecological and genetic approaches to contribute to our understanding of the roles of reproduction and dispersal in maintaining biodiversity. We will determine whether some loca ....Setting the limits: Ecological and genetic tests of the status of marine populations at species borders. The wide dispersion of Australia's population along our coastal fringe combined with global climate change poses severe threats to marine biodiversity and necessitates urgent conservation measures. Our study will use ecological and genetic approaches to contribute to our understanding of the roles of reproduction and dispersal in maintaining biodiversity. We will determine whether some locations are highly productive sources of larval colonists, whereas others are unproductive and dependent on other sources of recruits, and we will inform management practices such as the creation of marine protected areas.Read moreRead less
Ecology, Physiology and Phylogeography: an integrated approach to the study of the invasive marine green macroalga Caulerpa taxifolia in Australia. The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000.

The green marine macroalga Caulerpa taxifolia is one of the world's worst invasive species. In Australia 'exotic strains' of this alga are a listed pest species. Invasions in NSW and SA have caused environmental harm and managing them has cost $10 million since 2000. We propose to integrate ecology, physiology and genetic analyses to provide data to better respond to this pest, potentially savings millions of dollars per year. We will produce the first empirical evidence of the effects of climate change and ocean acidification on this marine pest, in the context of increasing coastal human populations.Read moreRead less
