The evolutionary transition from anaerobic to aerobic metabolism. This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in ....The evolutionary transition from anaerobic to aerobic metabolism. This project aims to find out how life on Earth survived the revolutionary changes when cyanobacteria first released oxygen into the atmosphere. These events led to a transition from anoxic (oxygen-free) to oxic (oxygen-rich) conditions. A comparative genomic view across a series of photosynthetic organisms will be performed at the molecular level with ecological interpretation. Understanding of what metabolic changes occurred in response to the shifts in the environment will have wide implications for predicting the evolutionary events that are still occurring today, such as rapidly changing climatic conditions. This fundamental research will enhance Australia's profile in this field.Read moreRead less
Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their p ....Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their protection; in aquaculture, selecting for productive fish will also increase aggression-related injuries. If not strongly linked, we may be able to select for high productivity and low aggression in fish, or high productivity and low metabolism, thus reducing feed costs in aquaculture associated with aggressive behaviour leading to injury and infection, and reduced growth at warmer temperatures.Read moreRead less
Novel Chlorophylls and New Directions in Photosynthesis. Understanding how solar energy is used in photosynthesis is of global importance and will contribute to cutting-edge photosynthetic research by Australian scientists. We aim to discover how and why the key photosynthetic pigments, chlorophylls, are synthesised and used; this will provide new opportunities for breakthroughs in frontier technologies, such as photoelectric cells based on carbon rather than silicon. We aim to understand how no ....Novel Chlorophylls and New Directions in Photosynthesis. Understanding how solar energy is used in photosynthesis is of global importance and will contribute to cutting-edge photosynthetic research by Australian scientists. We aim to discover how and why the key photosynthetic pigments, chlorophylls, are synthesised and used; this will provide new opportunities for breakthroughs in frontier technologies, such as photoelectric cells based on carbon rather than silicon. We aim to understand how novel chlorophylls are used in a variety of important organisms in a range of ecological niches. The results will aid understanding of the effects of global climate change on coral reefs, in open-ocean systems and in other important biological communities.Read moreRead less
Invasive plant species and climate change in Australia: predicting the threat and projecting the future. The interaction between climate change and invasive pest species poses a significant threat to Australia's biodiversity. The need for research on both the independent impacts of climate change and invasive species, as well as their interaction, has been clearly identified by both national and state governments, and is identified as a priority under the National Biodiversity and Climate Change ....Invasive plant species and climate change in Australia: predicting the threat and projecting the future. The interaction between climate change and invasive pest species poses a significant threat to Australia's biodiversity. The need for research on both the independent impacts of climate change and invasive species, as well as their interaction, has been clearly identified by both national and state governments, and is identified as a priority under the National Biodiversity and Climate Change Action Plan (2004-2007). The proposed research will assess exotic plant species' responses to climate change, identify potential hotspots of invasion, and provide a risk assessment framework to enable prioritization of exotic plant management under future climate.Read moreRead less
