Animals response to extreme climatic events. Climate change is causing extreme climatic events, such as floods and heat waves, to become more frequent. This project will investigate by which mechanism animals can adjust to extreme climatic events and whether the response is fast enough to avoid extinction, thereby providing urgently needed insights into the natural resilience of Australian fauna.
Conservation genomics of a critically endangered insect. This project aims to develop tools genotyping large animal genomes, focusing on the case of the Lord Howe Island stick insect, once thought to be extinct and now critically endangered. This project expects to generate molecular tools to monitor the genetic health the insect which has a large, complex and poorly understood genome. Expected outcomes include the development of a preservation and reintroduction strategy for the insect. This pr ....Conservation genomics of a critically endangered insect. This project aims to develop tools genotyping large animal genomes, focusing on the case of the Lord Howe Island stick insect, once thought to be extinct and now critically endangered. This project expects to generate molecular tools to monitor the genetic health the insect which has a large, complex and poorly understood genome. Expected outcomes include the development of a preservation and reintroduction strategy for the insect. This project will benefit ongoing conservation efforts, and is timely given the ongoing eradication of rats from Lord Howe Island where this species once lived. Read moreRead less
Does dynamic ecological change cause rapid evolution? This project aims to increase understanding of how Australia’s native biota responds to rapid environmental changes. Abrupt environmental change has the potential to drive rapid evolution, which may facilitate species persistence in the face of novel challenges. This project will use long-term genomic data to quantify rates of evolutionary change in species living in arid environments, whose populations fluctuate markedly in response to rainf ....Does dynamic ecological change cause rapid evolution? This project aims to increase understanding of how Australia’s native biota responds to rapid environmental changes. Abrupt environmental change has the potential to drive rapid evolution, which may facilitate species persistence in the face of novel challenges. This project will use long-term genomic data to quantify rates of evolutionary change in species living in arid environments, whose populations fluctuate markedly in response to rainfall variation. By measuring the pace of genomic change in these species, and the evolutionary processes driving that change, this project will reveal species’ evolutionary responses to major environmental fluctuations.Read moreRead less
Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish gr ....Understanding climate and harvest induced changes in fish life histories. This project aims to quantify the cumulative impacts of harvest and climate change across marine fishes and ecosystems. The project expects to generate new knowledge in this area by coupling the rich biological information archived in fish ear bones, with targeted multi-generation experiments and predictive modelling. Expected outcomes include fundamental insights into how human-induced environmental change affects fish growth and maturation, and a subsequent critical evaluation of the sensitivity of fisheries models to trends in these life-history traits. This should provide significant benefits to fisheries and ecosystem management, ensuring they remain productive and resilient in a time of rapid environmental change.Read moreRead less
The intensity of sexual selection with density and age and its importance in the evolution of animal populations. Australia is internationally highly regarded for the quality of its research into the basic biology of its fauna. This study will provide information on the breeding biology of an endemic marine species distributed across the Northern tropics of Australia. It addresses a pure research question of great theoretical interest. However, it also provides valuable training opportunities fo ....The intensity of sexual selection with density and age and its importance in the evolution of animal populations. Australia is internationally highly regarded for the quality of its research into the basic biology of its fauna. This study will provide information on the breeding biology of an endemic marine species distributed across the Northern tropics of Australia. It addresses a pure research question of great theoretical interest. However, it also provides valuable training opportunities for postgraduate students in the practicalities of conducting tropical field biology and the execution of field experiments. These are essential skills that can readily be transferred to applied biological problems. Maintaining a pool of skilled field biologists is essential for the on-going success of programmes in conservation and ecosystem management. Read moreRead less
Fighting for space: How do weaker individuals compete? Animals fight for territories and larger, stronger individuals usually win. How then, in fiddler crabs, do small males and weaponless females defend their territories against larger males? I will investigate four contexts in which strength alone may not determine fighting success. I predict that: (a) positional and motivational advantages allow territory owners to repel intruders; (b) weak individuals compete with stronger neighbours by 'nag ....Fighting for space: How do weaker individuals compete? Animals fight for territories and larger, stronger individuals usually win. How then, in fiddler crabs, do small males and weaponless females defend their territories against larger males? I will investigate four contexts in which strength alone may not determine fighting success. I predict that: (a) positional and motivational advantages allow territory owners to repel intruders; (b) weak individuals compete with stronger neighbours by 'nagging' rather than by winning fights; (c) residents form coalitions to fend off intruders; and d) females, who lack the large claws of males, employ novel alternative tactics to maintain territories.This study will test important theories of territoriality and in so doing make a major contribution to behavioural ecology.

Landscape restoration genomics for climate adaptation in eucalyptus foundation species. Understanding the genetic basis of adaptation in foundation species will allow selection of pre-adapted seeds to establish resilient ecosystems which support the broad range of life supporting services. This project will apply genomics to solve real environmental challenges in restoration management and be a model for other foundation species.
Evolution in a changing environment. Climate change is having dramatic effects on wild animal populations. This project will investigate how and why these effects occur, and whether populations will be able to evolve to adapt to a changing environment.
Moving between day and night: Navigational strategies and foraging costs of temporal niche partitioning. This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches. It will make use of the unique research opportunities in Australia, by working with endemic fauna that allows scientists to address questions that would otherwise be hard to answer. The project will introduce the novel technique of differenti ....Moving between day and night: Navigational strategies and foraging costs of temporal niche partitioning. This study involves fundamental research to identify the navigational strategies and the foraging cost in animals that occupy different temporal niches. It will make use of the unique research opportunities in Australia, by working with endemic fauna that allows scientists to address questions that would otherwise be hard to answer. The project will introduce the novel technique of differential GPS to track the paths of ants which has the potential to revolutionise the field of insect navigation. Salience-dependent navigational strategies analysed in this study will be of great interest in the field of engineering and robotics.Read moreRead less
