Summary
How does the brain process conflicting information? Learning is the means by which we adapt to our environments. Occasionally, what we learn contradicts our present knowledge about the world. When this occurs, the old and new (contradictory) information compete for control over behaviour. Yet, how the brain processes contradictory information and resolves this competition is poorly understood. This project uses modern genetic tools in rodents to examine how the brain encodes and retrieves contra ....How does the brain process conflicting information? Learning is the means by which we adapt to our environments. Occasionally, what we learn contradicts our present knowledge about the world. When this occurs, the old and new (contradictory) information compete for control over behaviour. Yet, how the brain processes contradictory information and resolves this competition is poorly understood. This project uses modern genetic tools in rodents to examine how the brain encodes and retrieves contradictory information to influence behaviour. The outcomes include new insights regarding the neural basis of adaptive behaviour; and the benefits include an understanding of why we sometimes fail to adapt to change, and disorders characterized by such failures (e.g., anxiety disorders, addiction).Read moreRead less
Risky choices: From cells and circuits to computations and behaviour. This project aims to ask and answer fundamental questions about how we safely make risky decisions to guide our behaviour. It combines theoretically driven approaches from experimental psychology with state-of-the-art technology for mapping and manipulating brain function.

This project aims to ask and answer fundamental questions about how we safely make risky decisions to guide our behaviour. It combines theoretically driven approaches from experimental psychology with state-of-the-art technology for mapping and manipulating brain function. The project expects to show, with unprecedented behavioural, brain cell type, and circuit precision, how we safely make choices, how these choices are shaped by experience, and how controlling these cells and circuits controls choice. This outcome should provide significant benefits including a new knowledge base bridging behavioural, cognitive, and neural sciences to advance theories of behaviour and laying a new basic science platform to understand impulsive behaviours.Read moreRead less
Animal social behaviour and emerging infectious fungal diseases in nature. This project aims to improve knowledge about the central role that animal social behaviour plays in the spread of emerging infectious fungal diseases in nature.

This project aims to improve knowledge about the central role that animal social behaviour plays in the spread of emerging infectious fungal diseases in nature. Applying approaches from behavioural ecology, network modelling and quantitative genetics, and utilising rare empirical pre- and post-infection data, the project expects to generate new understandings about how fungal diseases spread through animal populations, how animal social behaviour influences disease transmission, and how disease-status affects animal social behaviour. This project should have international impact, and advance current knowledge about disease dynamics. Applied outcomes should inform much-needed control strategies to benefit wildlife and preserve biodiversity. Read moreRead less
Endocrine disruption in wildlife: a sexual selection perspective . The Project aims to uncover how environmental pollution by hormone-mimicking chemicals affects wildlife behaviour, reproductive performance, and offspring viability. Through an integrative approach that combines multigenerational laboratory studies with an experimental evolution perspective, the Project expects to yield important insights into the pervasive influence of chemical contaminants on biological systems, and the capacit ....Endocrine disruption in wildlife: a sexual selection perspective . The Project aims to uncover how environmental pollution by hormone-mimicking chemicals affects wildlife behaviour, reproductive performance, and offspring viability. Through an integrative approach that combines multigenerational laboratory studies with an experimental evolution perspective, the Project expects to yield important insights into the pervasive influence of chemical contaminants on biological systems, and the capacity for animals to adapt to environments degraded by human activity. Findings will enable predictions of the ecological and evolutionary consequences of anthropogenic change, and contribute new knowledge relevant to the management of Australia’s biodiversity and the security of its sensitive freshwater resources.Read moreRead less
Ejaculate-mediated paternal effects on offspring fitness. This project aims to unravel the evolutionary importance of ejaculate-mediated paternal effects, through which paternal lifestyle factors, such as diet and exposure to toxicants, influence offspring growth and health independently of genes. By identifying the molecular mechanisms underlying these non-genetic sources of inheritance, their adaptive value, and their potential to fuel evolutionary change, the project expects to generate new k ....Ejaculate-mediated paternal effects on offspring fitness. This project aims to unravel the evolutionary importance of ejaculate-mediated paternal effects, through which paternal lifestyle factors, such as diet and exposure to toxicants, influence offspring growth and health independently of genes. By identifying the molecular mechanisms underlying these non-genetic sources of inheritance, their adaptive value, and their potential to fuel evolutionary change, the project expects to generate new knowledge that will be relevant across the biological, medical and agricultural sectors. Expected outcomes and benefits include building institutional and interdisciplinary collaborations and the development of tools to understand the evolutionary impacts of paternal lifestyle choices for offspring traits.Read moreRead less
How drugs in the wild affect animal behaviour, ecosystems, and evolution. This Project aims to track – with fish species and across different modes, scales, and levels of complexity from controlled laboratory experimentation to studies in the wild – how drugs in the environment affect wildlife behaviour and survival, and therefore also the ecological communities they inhabit. Contamination of aquatic habitats by pharmaceuticals poses a serious threat to wildlife and to human health. Expected out ....How drugs in the wild affect animal behaviour, ecosystems, and evolution. This Project aims to track – with fish species and across different modes, scales, and levels of complexity from controlled laboratory experimentation to studies in the wild – how drugs in the environment affect wildlife behaviour and survival, and therefore also the ecological communities they inhabit. Contamination of aquatic habitats by pharmaceuticals poses a serious threat to wildlife and to human health. Expected outcomes include new mechanistic understandings and predictive capability for real world application. Findings should add significantly to our knowledge of how wildlife respond to environmental change, and enhance the evidence base for management and security of Australia’s biodiversity and freshwater resources.Read moreRead less

The plight of the bogong moth: a model for conservation in Australia. This project aims to direct conservation actions for the bogong moth, an endangered species of profound cultural, ecological, and economic importance to Australians. Although iconic and famous for their epic migration to the Australian Alps, the bogong moth's distribution and flyways are unknown making conservation actions impossible. This project expects to forge the key partnerships and harness public enthusiasm to generate ....The plight of the bogong moth: a model for conservation in Australia. This project aims to direct conservation actions for the bogong moth, an endangered species of profound cultural, ecological, and economic importance to Australians. Although iconic and famous for their epic migration to the Australian Alps, the bogong moth's distribution and flyways are unknown making conservation actions impossible. This project expects to forge the key partnerships and harness public enthusiasm to generate the data needed for conservation actions via a National Bogong Moth Observatory. The expected outcomes of this project are enhanced capacity to identify and mitigate threats to bogong moths. This should provide significant benefits such as a highly transferable model for continent-wide conservation in Australia.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
Sexual conflict and the evolution of nuptial gifts. This project aims to understand how sexual conflict drives the evolution of “manipulative” nuptial gifts in male arthropods and how females respond to ingesting these gifts. Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce ....Sexual conflict and the evolution of nuptial gifts. This project aims to understand how sexual conflict drives the evolution of “manipulative” nuptial gifts in male arthropods and how females respond to ingesting these gifts. Nuptial food gifts comprise materials (other than sperm) that are offered by males to females to consume at mating, and are an integral feature of the mating systems of a wide variety of arthropods. The project will study the decorated cricket, a species where males produce a nuptial food gift that contains a cocktail of chemicals known to influence female reproduction when eaten. The project is expected to strengthen Australia’s international standing in evolutionary research and help train the next generation of evolutionary biologists.Read moreRead less
The fitness consequences of age-dependent changes in cognitive abilities. This project aims to investigate health-related topics in invasive fish. The evolution of large brains suggests that smarter individuals have more offspring due to natural and sexual selection. This project aims to test if the ability to perform cognitively challenging tasks predicts reproductive success. In addition, many life history traits show a trade-off between early and late life performance. This project will test ....The fitness consequences of age-dependent changes in cognitive abilities. This project aims to investigate health-related topics in invasive fish. The evolution of large brains suggests that smarter individuals have more offspring due to natural and sexual selection. This project aims to test if the ability to perform cognitively challenging tasks predicts reproductive success. In addition, many life history traits show a trade-off between early and late life performance. This project will test this prediction to see if individuals with above average cognitive performance when young are below average when old, that is faster 'cognitive senescence', or whether some individuals stay relatively smarter than others throughout their lives.Read moreRead less
