Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for p ....Predicting adaptive responses to climate change in Australian native bees. This project aims to understand how insects will adapt to climate change by examining a largely overlooked but economically important group of species: Australian native bees. Native bees are important pollinators of both crops and native plants, but their sensitivity to changes in climate are unknown. Expected outcomes include new knowledge of the resilience of native bees to climate change, and new effective tools for predicting climate change resilience that can be applied to many species. The intended benefits include increasing our understanding of the potential for native bees to act as future pollinators in Australia’s natural and agro-ecosystems, and guide policy and management decisions to better protect and conserve our bee fauna.Read moreRead less
Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogene ....Evolution in action or the demise of iconic Australian flora? The project aims to investigate the evolutionary history and conservation status of a group of closely related Grevillea species, in the light of increasing pressure from landscape modification. This project will incorporate leading methodologies for massively parallel sequencing, pollinator preference and breeding capacity in order to detect the patterns and processes underpinning divergence in widely distributed species. A phylogenetic framework will provide the evolutionary relationships among taxa. This project is expected to inform requirements for long-term species persistence and, for threatened species within the group, guide the decision making of biodiversity managers as to what actions are required and where best to invest limited funds.Read moreRead less
Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their p ....Linkages between productivity and consistent behavioural traits in fish: implications for harvesting, climate impacts, and selective breeding for aquaculture. The extent to which behavior, growth and reproduction are genetically linked in fish populations is unknown, but critical for predicting the impacts of fish harvesting and climate warming, and developing fish stains for aquaculture. If strongly linked, fish harvest will always remove aggressive, large and productive fish, requiring their protection; in aquaculture, selecting for productive fish will also increase aggression-related injuries. If not strongly linked, we may be able to select for high productivity and low aggression in fish, or high productivity and low metabolism, thus reducing feed costs in aquaculture associated with aggressive behaviour leading to injury and infection, and reduced growth at warmer temperatures.Read moreRead less
Frayed at the edges? Integrating evolutionary genetics into the study of species distributional limits. Restricted species, like those in rainforests, represent the vast majority of biodiversity, but they face high risks of extinction due to climate change unless they can adapt. Using butterflies as a model, this project will examine whether rainforest restricted species are able to adapt to future climate change and provide insight into their extinction risk.

Summary
Does spurious maternal-fetal signalling support the evolution of a placenta. This project aims to test a model that explains how the placenta has evolved as a new organ more than 100 times in fishes, reptiles, and mammals including our own ancestors. The project will assess whether regulatory components of the placenta evolve as a result of spurious maternal-fetal signalling following egg retention and eggshell loss in viviparous reptiles. Expected outcomes of this project include a new understa ....Does spurious maternal-fetal signalling support the evolution of a placenta. This project aims to test a model that explains how the placenta has evolved as a new organ more than 100 times in fishes, reptiles, and mammals including our own ancestors. The project will assess whether regulatory components of the placenta evolve as a result of spurious maternal-fetal signalling following egg retention and eggshell loss in viviparous reptiles. Expected outcomes of this project include a new understanding of how complex organs originate and evolve in animals. This will benefit society through a broader depth of understanding of our own evolutionary history and provides a framework for future studies to investigate the origin and evolution of organs more broadly in animals.Read moreRead less
The evolution of female resistance to male reproductive traits in animals. Australia has an outstanding international reputation in the fields of Ecology and Evolution. This study will reinforce Australia's excellence in these fields. Sexual conflict is a topic of great scientific interest because it has important implications for evolutionary theory and our understanding of the diverse strategies that animals use to attract or repel potential mates. Consequently, articles on this topic feature ....The evolution of female resistance to male reproductive traits in animals. Australia has an outstanding international reputation in the fields of Ecology and Evolution. This study will reinforce Australia's excellence in these fields. Sexual conflict is a topic of great scientific interest because it has important implications for evolutionary theory and our understanding of the diverse strategies that animals use to attract or repel potential mates. Consequently, articles on this topic feature regularly in top international scientific journals. In addition, research on the unique social behaviours of Australian animals holds general public interest and plays an important role in attracting young people to careers in science.
