Intersexual arms races - are individuals within marine meta-populations less able to interbreed than assumed? A meta-population structure is thought to describe the inter-connected nature of many populations of marine animals with dispersive larvae. However, new theory predicts some of these populations might be not very inter-connected at all, despite larval migration. In some circumstances, independent, co-evolutionary arms races between sexes might develop within local populations, resulting ....Intersexual arms races - are individuals within marine meta-populations less able to interbreed than assumed? A meta-population structure is thought to describe the inter-connected nature of many populations of marine animals with dispersive larvae. However, new theory predicts some of these populations might be not very inter-connected at all, despite larval migration. In some circumstances, independent, co-evolutionary arms races between sexes might develop within local populations, resulting in individuals becoming increasingly less able to interbreed freely. I will directly test for this, measuring how successfully broadcast spawners can cross-fertilise across populations. This will reveal the genetic structure of these populations and if these animals really do live in a meta-population.Read moreRead less

Summary
Interdisciplinary Network for Aquatic Animal Health. The value of Australian fisheries and aquaculture is increasing significantly and, whilst this has resulted in an increase in R&D spending in the area, stifled collaboration amongst isolated scientists sometimes results in slow research progress. This network will enhance research on aquatic animal health. Our main aim is to provide a stimulating environment, encourage collaboration and ensure fast flow of interdisciplinary information between ....Interdisciplinary Network for Aquatic Animal Health. The value of Australian fisheries and aquaculture is increasing significantly and, whilst this has resulted in an increase in R&D spending in the area, stifled collaboration amongst isolated scientists sometimes results in slow research progress. This network will enhance research on aquatic animal health. Our main aim is to provide a stimulating environment, encourage collaboration and ensure fast flow of interdisciplinary information between researchers. We will adapt methods and technologies from medical research and other disciplines to increase our understanding of aquatic animal health and at the same time ensure that our results are applied in other disciplines.Read moreRead less
Variation in larval gene expression in a marine invertebrate: implications for population divergence via differential settlement response. Evolutionary and ecological functional genomics is an emerging field that integrates gene profiling technologies with experimental and field approaches of ecology and evolution. I take this approach to address a key problem in marine invertebrate biology: how do larvae respond to their environment and how does variation in this response influence the distribu ....Variation in larval gene expression in a marine invertebrate: implications for population divergence via differential settlement response. Evolutionary and ecological functional genomics is an emerging field that integrates gene profiling technologies with experimental and field approaches of ecology and evolution. I take this approach to address a key problem in marine invertebrate biology: how do larvae respond to their environment and how does variation in this response influence the distribution and evolution of a species? I will use a marine gastropod (abalone) model, for which there exists substantial development and population genetic data, and established aquaculture methodologies. Outcomes of this study will enhance knowledge of the stock structure of this and other commercial fisheries, as well as aquaculture efficiency.Read moreRead less
