Evolutionary genetics of kin recognition and task specialization in termite societies. Social insects must be able to recognize kin and task specialize in order to maintain colony cohesion and maximize colony labour, respectively. While it is known that kin recognition and task specialization are two key mechanisms underpinning insect societies, the extent to which their expression is mediated by genetic versus environmental variables is not known. This project integrates classic approaches to t ....Evolutionary genetics of kin recognition and task specialization in termite societies. Social insects must be able to recognize kin and task specialize in order to maintain colony cohesion and maximize colony labour, respectively. While it is known that kin recognition and task specialization are two key mechanisms underpinning insect societies, the extent to which their expression is mediated by genetic versus environmental variables is not known. This project integrates classic approaches to the study of animal behaviour with recent advances in molecular genetics to test, for the first time, the role that genetic variables have in mediating kin recognition and task specialization in a major group of social insects, the termites.Read moreRead less
Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mech ....Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mechanisms to ensure that managers of Australia's reefs have critical information on how past disturbance frequency and intensity has affected coral reef communities. This information will help ensure the continuation of ecosystem goods and services from Australia's high diversity coral reefs.Read moreRead less
Catch me if you can: predator recognition and anti-predator behaviour in marine fishes. Increased understanding of the interactions between prey and their predators that have shaped the fish communities that inhabit today's coral reefs will aid in predicting how they will respond to future perturbations such as increased fishing pressure, range shifts caused by climate change, or species introductions. This will provide national economic benefits by increasing our ability to manage coral reefs, ....Catch me if you can: predator recognition and anti-predator behaviour in marine fishes. Increased understanding of the interactions between prey and their predators that have shaped the fish communities that inhabit today's coral reefs will aid in predicting how they will respond to future perturbations such as increased fishing pressure, range shifts caused by climate change, or species introductions. This will provide national economic benefits by increasing our ability to manage coral reefs, such as the Great Barrier Reef, a World Heritage Site of great economic importance for fisheries and ecotourism.

How does allocation to each sex evolve in hermaphrodites? New insight from the sea. Understanding the ability of hermaphroditic animals to adapt their sex allocation to suit environmental conditions will pave the way for integration between pure and applied research. Such understanding can provide stakeholders across a range of disciplines (natural resource management, aquaculture, conservation) with key information about genetic and environmental influences on the reproduction of many species o ....How does allocation to each sex evolve in hermaphrodites? New insight from the sea. Understanding the ability of hermaphroditic animals to adapt their sex allocation to suit environmental conditions will pave the way for integration between pure and applied research. Such understanding can provide stakeholders across a range of disciplines (natural resource management, aquaculture, conservation) with key information about genetic and environmental influences on the reproduction of many species of significant ecological, economic and social value with this mating system. This research will yield knowledge at the very forefront of evolutionary ecology, enhancing Australia's reputation for research excellence in this field, and further benefit Australian science through the training of young scientists.Read moreRead less
