Understanding individual differences in social behaviour: the role of personality. This project will investigate how behavioural differences, between individuals, influence key ecological decisions in social animals. The results will shed light on fundamental biological processes, with implications for such diverse applied areas as wildlife management, animal welfare and husbandry, pharmacology, disease risk and job satisfaction.

This project aims to enhance understanding of visual neuroscience, genetic control of vision and environmental ecology on The Great Barrier Reef (GBR). Using the anemonefish as a model, together with new genetic, photographic and behavioural approaches, the project aims to reveal novel aspects of colour vision on the reef. Outcomes beyond multiple scientific disciplines include enhanced international collaboration and building capacity for improved reef guardianship. The benefits are scientific discovery in multiple areas, providing greater community understanding of complex science and a desire to preserve the GBR for future generations.Read moreRead less
The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to unde ....The sparrows in the mining towns: a century of adaptation to contamination. Our research will characterise how contamination from the extraction of precious metals can spread through the environment and how it effects a highly urbanised bird – the house sparrow. In many cases, populations of these birds have been intimately associated with mining operations for over a century, and our recent work has provided evidence of adaptation over time. House sparrows provide a great natural system to understand the genetic potential of organisms to adapt to anthropomorphic change in the environment connected with the resources industry. Our work, will bring new insight into the future management of environmental contamination, and the mitigation of adverse effects arising from resource extraction.Read moreRead less
Female multiple mating and the evolutionary origins of complex societies. This project plans to connect micro-evolutionary processes with macro-evolutionary change to provide a unified understanding of why animals live together. Evolutionary transitions to and from complex social behaviour appear linked to female multiple mating (polyandry). However, the causal pathway by which variation in polyandry results in the emergence and diversification of sociality is yet to be established. Using a vert ....Female multiple mating and the evolutionary origins of complex societies. This project plans to connect micro-evolutionary processes with macro-evolutionary change to provide a unified understanding of why animals live together. Evolutionary transitions to and from complex social behaviour appear linked to female multiple mating (polyandry). However, the causal pathway by which variation in polyandry results in the emergence and diversification of sociality is yet to be established. Using a vertebrate system we aim to integrate empirical, theoretical and comparative approaches to show: the ecological causes of individual variation in female polyandry; its effect on social behaviours that promote social complexity at the population level; and how this corresponds to divergence in social complexity across species.Read moreRead less
Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environmen ....Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environments. The project could generate new insight into the processes that promote and constrain phenotypic diversity in nature.Read moreRead less

Summary
How the visual environment affects the diversity of avian colours and why this matters. Evolutionary theory predicts that (a) animal colours are optimised to perform best in their native environment and hence that (b) environmental degradation can disrupt the function of animal colours in communication or camouflage. This project will test these predictions for Australian birds and use the outcome to inform environmental restoration programs.
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 danger within: assessing the threats to an endangered finch from genetic incompatibility, limited dispersal and effective population size. The Gouldian finch has declined dramatically over the past half century and remains one of Australia's most threatened birds. This project will use some cutting edge genetic techniques to understand some of the processes that undermine the species' recovery and our ability to monitor current populations.
Dining with Dasyurids: Using Nutritional Geometry to Improve Diets for Captive Breeding Programs. Captive breeding programs are an important part of conservation and reintroduction plans for endangered Northern quolls and Tasmanian devils. This project aims to initiate new collaboration between the Charles Perkins Centre and Taronga Conservation Society to improve diets for captive breeding of marsupial carnivores using the framework of nutritional geometry.

Captive breeding programs are an important part of conservation and reintroduction plans for endangered Northern quolls and Tasmanian devils. This project aims to initiate new collaboration between the Charles Perkins Centre and Taronga Conservation Society to improve diets for captive breeding of marsupial carnivores using the framework of nutritional geometry. Specifically, the project aims to: quantify the macronutrient (carbohydrate, lipid and protein) targets and regulatory behaviour of marsupial carnivores; test explanations for why animals are prone to excess weight gain in captivity; and quantify changes in nutrient targets with reproduction. These results aims to be applied by Taronga to improve captive-diets for marsupial carnivore breeding programs.Read moreRead less

The role of enemies in the generation of biodiversity. A fundamental question in biology is how new species are generated. The role of abiotic factors has been widely explored, but there is still little known about the role that ecological or behavioural interactions between organisms, such as parasitism or predation, play in the generation of diversity. This project aims to test the importance of anti-predator defences (warning colours) in generating species.

The role of abiotic factors has been widely explored, but there is still little known about the role that ecological or behavioural interactions between organisms, such as parasitism or predation, play in the generation of diversity. This project aims to test the importance of anti-predator defences (warning colours) in generating species. It will combine micro- and macroevolutionary analyses to provide an in-depth test of this association. This project aims to provide a bridge between behavioural ecology and macroevolutionary processes, using Australian fauna, and increase our knowledge about whether and how enemies can contribute to generating diversity of life on earth.Read moreRead less
