LARVAL RETENTION AND CONNECTIVITY IN CORAL REEF FISH POPULATIONS: A MULTI-TECHNIQUE APPROACH. A key unanswered question in marine ecology and fisheries management is - are planktonic juveniles retained within or transported among populations? The only three techniques that can potentially quantify larval dispersal distances are genetic markers, natural chemical signatures and applied chemical marks. This project combines, for the first time, all three techniques to measure the scale of disper ....LARVAL RETENTION AND CONNECTIVITY IN CORAL REEF FISH POPULATIONS: A MULTI-TECHNIQUE APPROACH. A key unanswered question in marine ecology and fisheries management is - are planktonic juveniles retained within or transported among populations? The only three techniques that can potentially quantify larval dispersal distances are genetic markers, natural chemical signatures and applied chemical marks. This project combines, for the first time, all three techniques to measure the scale of dispersal in two coral reef fish species. The relative importance of retention and connectivity will be measured, from a large scale encompassing different regions (Great Barrier Reef and Papua New Guinea) to a small scale focussing on individual reefs.Read moreRead less
Solar radiation, coral bleaching and climate change. Corals reefs like the Great Barrier Reef (GBR) underpin approximately $2 billion annually in sustainable tourism and fisheries. Warming of Australia's tropical seas, however, has increased mass coral bleaching/mortality and is placing reefs like the GBR at increasing risk. Solar radiation (PAR, UVR) plays an important influence on the biological outcome of thermal stress. Understanding the role of solar radiation is critical if we are to unde ....Solar radiation, coral bleaching and climate change. Corals reefs like the Great Barrier Reef (GBR) underpin approximately $2 billion annually in sustainable tourism and fisheries. Warming of Australia's tropical seas, however, has increased mass coral bleaching/mortality and is placing reefs like the GBR at increasing risk. Solar radiation (PAR, UVR) plays an important influence on the biological outcome of thermal stress. Understanding the role of solar radiation is critical if we are to understand the changes that will occur on coral reefs as temperatures increase. This multidisciplinary international team will define and model the role of solar radiation on thermal stress at local, regional and global scales. Read moreRead less
Ecological consequences of global warming: predicting effects on biodiversity on intertidal assemblages on the east coast of Australia. Understanding what conserves biodiversity is a crucial challenge for Australian science. This research will provide critical information on the consequences of global climatic change: southerly shifts in distributions of animals due to rising temperatures; vertical shifts due to rising sea level and changes in amounts of food for grazing species. This informatio ....Ecological consequences of global warming: predicting effects on biodiversity on intertidal assemblages on the east coast of Australia. Understanding what conserves biodiversity is a crucial challenge for Australian science. This research will provide critical information on the consequences of global climatic change: southerly shifts in distributions of animals due to rising temperatures; vertical shifts due to rising sea level and changes in amounts of food for grazing species. This information will underpin the future management of conservation and will improve understanding on issues such as how and why species are able to invade new areas, the effects on the resident species and how species change distribution in relation to the availability of specific needs for habitat.Read moreRead less
MICROENDOLITHS, CORAL BLEACHING AND ENVIRONMENTAL CHANGE. Planning for sustainable use of ecosystems like the Great Barrier Reef (GBR) can only be done with an accurate understanding of how ecosystems are likely to change, and at what rate, under persistent climate change. This project, aligned with National Research Priority 'An Environmentally Sustainable Australia', will be performed over 3 oceans and focusing on the GBR, will contribute to the national benefit by rapidly improving our unders ....MICROENDOLITHS, CORAL BLEACHING AND ENVIRONMENTAL CHANGE. Planning for sustainable use of ecosystems like the Great Barrier Reef (GBR) can only be done with an accurate understanding of how ecosystems are likely to change, and at what rate, under persistent climate change. This project, aligned with National Research Priority 'An Environmentally Sustainable Australia', will be performed over 3 oceans and focusing on the GBR, will contribute to the national benefit by rapidly improving our understanding on one such major factor-the endolithic community in coral skeletons. It will allow better predictions of short and long-term consequences to reefs, and will also continue to show Australia's leadership in understanding the rate and direction of changes within coral reef ecosystems.Read moreRead less
