Resolving the warming East Australian Current's impact on a marine food web. This project aims to understand the effects of climate change on marine food webs, from plankton production to predation by iconic marine fauna, by integrating data on oceanographic conditions and fish distribution with the foraging patterns and breeding success of seabirds. Warming waters due to strengthening western boundary currents have unknown consequences for coastal marine food webs. Innovative prey capture signatures from accelerometers, and advanced movement models from satellite locations will show how predators locate and prey upon fish schools. Anticipated outcomes are insight into how changing resource availability in the oceans affects ecosystem resilience; improved viability for coastal industries; and ecosystem-based conservation management strategies.Read moreRead less
Testing the waters: impacts of contaminants on ecosystem structure and function in urban waterways. To ensure that people can swim, catch fish and enjoy the beauty of urban waterways we need to be able to predict the effects of more than one stressor at a time. This project will determine how nutrients and metals affect our waterways. Findings will help prioritise management actions that protect biodiversity and human uses of these systems.
Immediate and delayed changes to survival, physiology, reproduction and movement of chondrichthyans following capture stress. Many sharks and rays are negatively affected by the impact of fisheries capture, with unknown consequences. The project will measure changes to survival, physiology, reproduction and behaviour following capture to better understand and manage the impact of fisheries on these animals. This information is vital for their effective conservation.
Testing co-evolutionary processes driving venom diversity in tiger snakes. Testing co-evolutionary processes driving venom diversity in tiger snakes. This project aims to examine the geographic variation amongst tiger snakes in anatomy, ecology, and life history traits, and the relationship of these factors to venom toxins and production; and to evaluate the true pharmacological potential of tiger snake venom. This project will investigate the role of venom adaptation in long-term animal evoluti ....Testing co-evolutionary processes driving venom diversity in tiger snakes. Testing co-evolutionary processes driving venom diversity in tiger snakes. This project aims to examine the geographic variation amongst tiger snakes in anatomy, ecology, and life history traits, and the relationship of these factors to venom toxins and production; and to evaluate the true pharmacological potential of tiger snake venom. This project will investigate the role of venom adaptation in long-term animal evolution, by identifying rare venom transcripts involved in providing evolutionary potential for adaptation to environmental change. This is essential as continuing climatic and human-induced alteration of our environment affects southern Australia where many people live, work and interact with native wildlife. Anticipated outcomes are maximizing venom harvests and enhanced snakebite treatment capacity.Read moreRead less
Understanding animals through their movement. This project aims to develop a suite of analytical methods to understand animals' behaviour through their movement patterns. Animal movement patterns encode detailed information about their behavioural state. Collecting and analysing animal movement trajectories can provide us with completely new insights to behaviour. Recent developments in bio-logging technologies have provided an incredible amount of rich data on free-ranging animals. This project ....Understanding animals through their movement. This project aims to develop a suite of analytical methods to understand animals' behaviour through their movement patterns. Animal movement patterns encode detailed information about their behavioural state. Collecting and analysing animal movement trajectories can provide us with completely new insights to behaviour. Recent developments in bio-logging technologies have provided an incredible amount of rich data on free-ranging animals. This project will develop a suite of analytical techniques to interrogate this data through a combination of approaches, from fine scale experiments in the laboratory to tracking animal trajectories from the International Space Station. The findings will deliver major benefits to the broader community by transforming our ability to manage and conserve animal stocks.Read moreRead less
Testing the importance of large-scale climate factors to plant community assembly following land-use change. This project will examine the native plant species and functional diversity of Australia's rain forest communities to create a predictive framework of how plant communities recover following deforestation. Such a framework is key to focusing conservation efforts in degraded and multi-use landscapes.
Photosynthetic traits as “key performance indicators” of coral health. The objective of this project is to advance knowledge on the healthy functioning of the coral–algal symbiosis, which defines the response of coral reef ecosystems to worldwide environmental change. Current approaches to address this problem have linked coral health to algal symbiont diversity but have been unable to resolve the fundamental symbiont functional traits that govern this link – the “key performance indicators (KPI ....Photosynthetic traits as “key performance indicators” of coral health. The objective of this project is to advance knowledge on the healthy functioning of the coral–algal symbiosis, which defines the response of coral reef ecosystems to worldwide environmental change. Current approaches to address this problem have linked coral health to algal symbiont diversity but have been unable to resolve the fundamental symbiont functional traits that govern this link – the “key performance indicators (KPIs)”. This project plans to couple advanced physiological and functional genomics techniques to transform our understanding of how algal symbiont metabolic KPIs regulate coral growth and stress susceptibility. This may provide new diagnostic capability for the assessment of coral health and may enable us to improve coral reef ecosystem management.Read moreRead less
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
