Summary
Green or crispy: Which plants use transpiration to survive heatwaves? Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types cou ....Green or crispy: Which plants use transpiration to survive heatwaves? Heatwaves are increasing in frequency and intensity, and extreme heat poses a significant threat to tree growth and survival. This project aims to investigate how different Australian tree species respond to extreme heat by tracking dynamic changes in water use during both natural and experimental heatwaves, representing current and future stress levels. Identification of a predictable response among plant functional types could be used to better forecast the potential effects of climate change on forest ecosystems. This project also expects to identify heat-tolerant tree species and their relevant physiological traits, which can improve the success of urban tree plantings to help create cooler, greener cities throughout Australia.Read moreRead less
Manipulative mothers and family feuds: evolution of maternal effects under mother-offspring conflict. Can mothers shape the lives of their offspring and their grand-offspring? Can siblings shape the lives of their brothers and sisters? This project will address how mother and offspring strategies affect current and future generations. This is crucial for understanding how mothers will direct and accelerate evolutionary change in our changing world.
Sex chromosomes and speciation: chromosome inversion and the large Z-effect. This project aims to understand the divergence of species and the importance of two genomic features of often disproportionately large effect between young taxa – the sex chromosomes, and chromosome inversions. The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide sign ....Sex chromosomes and speciation: chromosome inversion and the large Z-effect.

The research will integrate genomics and transcriptomics with the study of traits closely aligned to speciation in birds – song, colour, and sperm morphology and protein composition. The project will provide significant benefits such as enhancing Australia’s strength in the field of evolutionary biology.Read moreRead less

Summary
The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit in ....The extent of competition between the native and introduced herbivores of Kangaroo Island. This project examines grazing behaviour and competition among native and introduced herbivores to optimise limited resources in an ecologically fragile environment. The project will provide a biological basis for the development of management strategies to provide positive outcomes for the Kangaroo Island environment and potential economic benefit to the local and national economy. Environmental benefit includes the reduction of total grazing pressure on pastures and native vegetation of Kangaroo Island, which is one of Australia’s top 15 biodiversity ‘hot spots’, and thus help with conservation efforts on Kangaroo Island. Economic benefit will follow if farmers receive income from a currently wasted resource.Read moreRead less
Testing metabolic theories in ecology. There are striking similarities in the way plants and animals take up and use energy (metabolism), despite enormous variation in size and life-style. This project will make the first experimental comparison of the predictions of the two major theories for these broad patterns. The results will significantly progress this controversial and exciting field.
Movement patterns and behavioural strategies of Estuarine Crocodiles: A long-term remote monitoring study using an underwater acoustic array. The on-going recovery of the estuarine crocodile population is creating a paradox for Australians. Although a salient species, an iconic animal, and a firm tourist attraction, estuarine crocodiles pose a significant risk to the public. Knowledge of where crocodiles go, what they do when they get there, and why they select particular habitats at certain tim ....Movement patterns and behavioural strategies of Estuarine Crocodiles: A long-term remote monitoring study using an underwater acoustic array. The on-going recovery of the estuarine crocodile population is creating a paradox for Australians. Although a salient species, an iconic animal, and a firm tourist attraction, estuarine crocodiles pose a significant risk to the public. Knowledge of where crocodiles go, what they do when they get there, and why they select particular habitats at certain times is critical for sustaining the Australian crocodile population, whilst ensuring public safety. This long term study will utilise the latest advancement in underwater acoustic technology to monitor the behavioural and physiological strategies used by estuarine crocodiles in occupying critical habitats, providing vital information for resource managers and policy makers.

Plastic pollution: new driver altering responses to variable environments. This project aims to determine how bisphenol A (BPA), which now represents a novel environmental driver, alters physiological responses of animals, and how it interacts with other environmental variables to alter ecological and evolutionary trajectories. Plastic pollution is a monumental global environmental and health problem, and Australia has one of the world’s highest exposures to BPA, a plastics leachate. This projec ....Plastic pollution: new driver altering responses to variable environments. This project aims to determine how bisphenol A (BPA), which now represents a novel environmental driver, alters physiological responses of animals, and how it interacts with other environmental variables to alter ecological and evolutionary trajectories. Plastic pollution is a monumental global environmental and health problem, and Australia has one of the world’s highest exposures to BPA, a plastics leachate. This project will use a new zebrafish gene knock-out model to show whether the effects of BPA are transferred between generations, and will establish an international collaboration, thereby increasing Australia's research capacity. Outcomes from the project are expected to benefit environmental management.Read moreRead less
Evolutionary roots of social bonds in female mammals. The social networks and friendships of wild female kangaroos and how these benefit individuals will be studied. This project will help us understand how the propensity of mammals to form friendships evolved; this understanding of the evolutionary roots of friendships will help in understanding why friendships affect peoples' health and mortality.

Summary
Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorpo ....Understanding the relationship between the social environment and cognition. The predominant theory for the evolution of intelligence, the social intelligence hypothesis (SIH), posits that within-group social interactions drive cognitive evolution. But the SIH overlooks a major component of social life: interactions with outsiders of the same species. Using a unique combination of meta-analytical and experimental approaches, the DECRA project will test the predictions of an expanded SIH, incorporating the “Napoleonic” cognitive challenges posed by outsiders. The expected outcome is to gain a new understanding of which factors govern cognitive evolution – one of the longest-running debates in evolutionary biology.Read moreRead less
Evolution of the mammalian baculum. This project aims to test the hypothesis that the shape of the mammalian baculum (penis bone) evolved via its stimulatory effects on females that promote reproduction. The baculum is the most morphologically divergent bone in the mammalian body. The reason for this divergence is one of the most puzzling enigmas of mammalian morphology. This project will use comparative evolutionary methods, quantitative genetics, morphometrics, behavioural analysis and techniq ....Evolution of the mammalian baculum.
