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.

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
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
Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding ....Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding, prey manipulation and the role of critical senses in the only captive population of sawfishes in Australia. Such knowledge will underpin the development and use of visual, chemical and/or magnetic repellents by fisherman that are still responsible for the loss of large numbers of sawfish as by-catch.Read moreRead less
How different is different: highly contrasting colours in animal patterns. Red apples in green trees and blue berries on the ground create very different visual signals to animals. Furthermore, elaborate animal colour patterns have evolved to render them conspicuous or camouflaged against their background. Despite the ecological and evolutionary importance of animal colour patterns, little is known about how larger colour contrasts and complex patterns are perceived by animals. This project aim ....How different is different: highly contrasting colours in animal patterns. Red apples in green trees and blue berries on the ground create very different visual signals to animals. Furthermore, elaborate animal colour patterns have evolved to render them conspicuous or camouflaged against their background. Despite the ecological and evolutionary importance of animal colour patterns, little is known about how larger colour contrasts and complex patterns are perceived by animals. This project aims to fill this knowledge gap specifically it endeavours: to provide useful tools for behavioural ecologists and visual neuroscientists, and to understand for the first time the full gamut of colour signalling in both terrestrial and aquatic environments.Read moreRead less
The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use ....The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use a multidisciplinary approach to explore what influences the quality of offspring spawned by adults, and whether offspring traits prior to or at hatching determine the identity of individuals that survive to join the reproductive population.Read moreRead less
Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the fir ....Resolving the threat of ocean deoxygenation to coral resilience. This project aims to uncover the role low oxygen plays in shaping healthy corals over space and time. Climate change and land use development are rapidly deoxygenating shallow water coral reefs, yet we have no knowledge of how less oxygen availability affects critical life history factors that govern coral resilience: growth, reproduction, and stress tolerance. This project unites a multidisciplinary team of experts to, for the first time, couple advanced oxygen sensing, metabolic physiology, coral reproductive and stress biology to transform our understanding of oxygen thresholds that are diagnostic of reduced coral competitive fitness across life stages (adults, juveniles, larvae), needed to improve coral reef ecosystem management.Read moreRead less
A paradigm shift for predictions of freshwater harmful cyanobacteria blooms. This project aims to advance model predictions to generate novel insights into the triggers of freshwater harmful cyanobacteria blooms. Current models are poorly adapted for this purpose because they fail to account for antecedent environmental forcing. The project is expected to create new knowledge of cyanobacteria dynamics from simulating the adaptive responses of individual cyanobacteria cells, colonies or filaments ....A paradigm shift for predictions of freshwater harmful cyanobacteria blooms. This project aims to advance model predictions to generate novel insights into the triggers of freshwater harmful cyanobacteria blooms. Current models are poorly adapted for this purpose because they fail to account for antecedent environmental forcing. The project is expected to create new knowledge of cyanobacteria dynamics from simulating the adaptive responses of individual cyanobacteria cells, colonies or filaments to temperature, light and nutrient history. Three field studies will be used to validate a new individual based model. The outcomes of this project will be valuable for managing freshwater ecosystems that are increasingly subject to blooms in a warming climate, and for testing suitable mitigation and control strategies.Read moreRead less
Climate change, larval dispersal and patterns of connectivity in coral metapopulations. Patterns of connectivity among coral populations are virtually unknown and these patterns are likely to change with changing climate. This project will test how temperature and pH will change patterns of coral dispersal in order to assist the design of an effective marine reserve network throughout the Great Barrier Reef.
