The mechanisms of settlement success in coral reef fishes. Most marine fishes, including commercial species, produce larvae that disperse in the open ocean. The short period during which these larval fishes leave the open water and take up residence on adult benthic habitat (settlement) is critical in determining the success of the population, but is poorly understood. Settling larvae differ in their physical attributes, including body size and physiological condition, both of which affect the ....The mechanisms of settlement success in coral reef fishes. Most marine fishes, including commercial species, produce larvae that disperse in the open ocean. The short period during which these larval fishes leave the open water and take up residence on adult benthic habitat (settlement) is critical in determining the success of the population, but is poorly understood. Settling larvae differ in their physical attributes, including body size and physiological condition, both of which affect their vulnerability to predators and their ability to compete for food and grow. By looking closely at this short life history stage, we hope to better understand how the supply of offshore larvae controls the production of marine fishes, including commercial fisheries.Read moreRead less
Conservation ecology of the black cod (Epinephelus daemelii). Black cod is a large, reef fish species that was once common and commercially important in NSW. Today, Black Cod is listed as vulnerable, and we know little more of their biology than when they were first protected in 1983. This project will significantly increase the effectiveness of Black cod management by determining their distribution, abundance, stock structure, fecundity, spawning behaviour and recruitment. This will allow imple ....Conservation ecology of the black cod (Epinephelus daemelii). Black cod is a large, reef fish species that was once common and commercially important in NSW. Today, Black Cod is listed as vulnerable, and we know little more of their biology than when they were first protected in 1983. This project will significantly increase the effectiveness of Black cod management by determining their distribution, abundance, stock structure, fecundity, spawning behaviour and recruitment. This will allow implementation of an effective recovery plan and a review of the status of Black Cod internationally and by the Federal Government. Collaboration with NSW Fisheries' Grey Nurse Shark program will allow assessment of the importance of Grey Nurse critical habitat areas in maintaining Black Cod populations.Read moreRead less
Living on the edge: settlement dynamics of reef fishes across their ranges. Settlement and early establishment (recruitment) are major determinants of population viability of marine organisms, and can vary greatly among oceans and latitudes. We will compare the recruitment dynamics of populations of reef fishes across their range, including at range boundaries where populations may be more vulnerable to environmental impact. We will test the hypothesis that a combination of highly erratic sett ....Living on the edge: settlement dynamics of reef fishes across their ranges. Settlement and early establishment (recruitment) are major determinants of population viability of marine organisms, and can vary greatly among oceans and latitudes. We will compare the recruitment dynamics of populations of reef fishes across their range, including at range boundaries where populations may be more vulnerable to environmental impact. We will test the hypothesis that a combination of highly erratic settlement, poor physiological condition of incoming larvae, and poor recruit growth and survivorship will occur at range boundaries. Outcomes of the study will help in prediction of the viability of fish populations which will improve their management and protection.Read moreRead less
Establishing a global framework to trace the provenance of seafood. The global importance and demand for seafood is higher than ever; yet, sustainable seafood production is threatened by seafood fraud. This research will develop a new technology that will trace the geographic origins of seafood from catch to table and empower authorities to combat fraud. In doing so, this research will use natural chemical variation in biominerals to build maps of ocean chemistry and create universal markers of ....Establishing a global framework to trace the provenance of seafood. The global importance and demand for seafood is higher than ever; yet, sustainable seafood production is threatened by seafood fraud. This research will develop a new technology that will trace the geographic origins of seafood from catch to table and empower authorities to combat fraud. In doing so, this research will use natural chemical variation in biominerals to build maps of ocean chemistry and create universal markers of seafood provenance. These markers will be intrinsically tamper-proof: enabling the chemical geolocation of seafood across international trade routes. The outcome of this research will address a global environmental challenge and, in doing so, deliver benefits to the Australian economy, consumer and environment. Read moreRead less
Can consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.
What happens to coral reefs without cleaner fish? Marine 'mosquitoes' regularly attack coral reef fish, but are controlled by parasite-eating cleaner fish. Cleaners positively affect reef communities in many ways and this is disproportionate to their tiny size and low density. Their removal for aquarium trades may have staggering effects on reefs. The project will determine how cleaners cause such effects.
Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which wat ....Understanding the survival of forests under drought . Droughts are predicted to become more extreme in the near future, with potentially devastating impacts on Australian forest ecosystems. This project aims to address key knowledge gaps in our understanding of how plants tolerate extreme drought stress and utilise this new knowledge to improve vegetation models suitable for assessing ecosystem vulnerability. We will use innovative experimental methodology to determine the processes by which water transport breaks down in roots, stems and leaves and the mechanisms governing recovery from severe drought stress. The project will provide a deeper understanding of drought tolerance in trees, improved forecasting of risks to native vegetation, and enhanced management of native forest resources.

Integrating biomechanics and ecology: moving from an individual- to population-level understanding of the effects of environmental change. Coral reefs, a key Australian resource, face an uncertain future due to environmental change. Up to now, environmental change research has focused on the individual level, severely limiting our predictive capacity. This project will develop a novel 'first principle' approach to solve this shortcoming and make population-level predictions possible.
The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lac ....The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lacking. This project intends to reveal the drivers of successful native invasions, evaluate their effect on fish diversity and productivity, and develop holistic models that forecast their effects on inshore fisheries species’ near-future distribution and stocks.Read moreRead less
