Understanding the impact of heat stress on cognition in a changing world. Our research will determine how anthropogenic climate change effects the ability of animals to process information in their environment. This research is significant because it directly addresses the growing issue of wildlife adaptation to climate change.

Our research will determine how anthropogenic climate change effects the ability of animals to process information in their environment. This research is significant because it directly addresses the growing issue of wildlife adaptation to climate change. If heat stress, reported widely in wildlife both in Australia and globally, impairs an animal's ability to respond to stimuli in its surrounding environment, then this may cause lower reproductive success (eg lower predator detection rates) and population declines. We aim to identify critical temperature points beyond which the cognitive responses of animals decline rapidly - a significant finding for effective wildlife management priorities in the face of rapid climate change.

Behavioural resilience to climatic variability. Despite Australian biota being adapted to high natural climate variability, modern climate change is leading to population collapses and shifts into novel ecosystems. This Project, which studies a unique native mammal in the Pilbara, aims to uncover whether changes in behaviour are effective for dealing with environmental extremes and unpredictable climatic conditions. It will integrate laboratory- and field-based investigations to examine behaviou ....Behavioural resilience to climatic variability. Despite Australian biota being adapted to high natural climate variability, modern climate change is leading to population collapses and shifts into novel ecosystems. This Project, which studies a unique native mammal in the Pilbara, aims to uncover whether changes in behaviour are effective for dealing with environmental extremes and unpredictable climatic conditions. It will integrate laboratory- and field-based investigations to examine behavioural responses to climatic variability and establish how these responses influence individual fitness and future population resilience. This research will advance knowledge on climate-driven behavioural adaptation and improve understanding of how species will cope with Australia’s changing climate.Read moreRead less
Male-male competition vs female choice: same-same or something different? This project aims to increase our understanding of the phenotypic, genetic and genomic outcomes of evolution, by both enhancing, and reversing, sexual selection in laboratory fruit flies. In doing so, this project expects to separate the entangled effects of female choice and male competition, generating new knowledge in evolutionary ecology and genetics. Expected outcomes of this project include identifying the separate m ....Male-male competition vs female choice: same-same or something different? This project aims to increase our understanding of the phenotypic, genetic and genomic outcomes of evolution, by both enhancing, and reversing, sexual selection in laboratory fruit flies. In doing so, this project expects to separate the entangled effects of female choice and male competition, generating new knowledge in evolutionary ecology and genetics. Expected outcomes of this project include identifying the separate molecular effects on the genome of selection through male competition and female choice. This should provide significant benefits in understanding the role of different forms of sexual selection in removing mutations and maintaining population fitness: vital factors in securing the long term viability of vulnerable species.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

Managing land surface radiation management to reduce the intensity of heat waves. This project aims to use land surface radiation management to reduce the intensity of heat waves. Heat waves have high social, environmental, and economic effects, and their intensity will increase. Using climate models, this project will examine how altering current land management practices could change properties of soils and vegetation to reduce the intensity of heat waves. The expected outcomes of this project ....Managing land surface radiation management to reduce the intensity of heat waves. This project aims to use land surface radiation management to reduce the intensity of heat waves. Heat waves have high social, environmental, and economic effects, and their intensity will increase. Using climate models, this project will examine how altering current land management practices could change properties of soils and vegetation to reduce the intensity of heat waves. The expected outcomes of this project are information on adaptation to the increasing intensity of heat waves in Australia, which will be applicable globally.Read moreRead less
Identifying potential trade-offs of adapting to climate change. Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of r ....Identifying potential trade-offs of adapting to climate change. Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of rapid selection and to disentangle the mechanisms of climate adaptation. Through a powerful combination of controlled experiments on known genotypes and cutting-edge transcriptomic approaches, this project will transform our understanding of the adaptability of foundation species in a rapidly changing ocean.

Understanding the relationship between sociality and cognition. The evolution of cognition is a fundamentally important yet poorly researched area. It has recently become clear that rather than measuring cognitive performance between species, understanding the causes of intraspecific variation in cognitive performance is vital to accurately measure the selective benefits of cognition. Recent groundbreaking research on Australian magpies has revealed individual differences in cognitive performanc ....Understanding the relationship between sociality and cognition. The evolution of cognition is a fundamentally important yet poorly researched area. It has recently become clear that rather than measuring cognitive performance between species, understanding the causes of intraspecific variation in cognitive performance is vital to accurately measure the selective benefits of cognition. Recent groundbreaking research on Australian magpies has revealed individual differences in cognitive performance are influenced by differences in sociality. This proposal will determine the causality of these results by examining the developmental and fitness consequences of individual differences in cognitive performance in relation to social interactions, thus directly addressing the sociality-cognition debate.Read moreRead less
Marine heatwaves drive loss of genetic diversity and selection in kelps. This project aims to unravel where and when marine heatwaves drive loss of genetic diversity and rapid directional selection in kelp forests.
