Adaptive evolution of coleoid (cuttlefish, octopus, squid) venoms. This project represents an opportunity for biodiscovery from the venoms of cuttlefish, octopuses and squids. The independent adaptation for venom active at the subzero Arctic and Antarctic polar waters is of particular evolutionary interest. However, their divergent, bioactive compounds are also a rich drug design resource.

Summary
Did colour vision evolve in the dark? This project aims to investigate the ability of fishes to perceive colour in dim-light conditions by studying representatives from two delicate and endangered ecosystems, coral reefs (nocturnal fish) and the deep-sea. Through a multidisciplinary approach to understanding colour vision and animal behaviour, this study expects to fill a knowledge gap in visual neuroscience and ecology while adding to the understanding of how marine creatures see and interact. ....Did colour vision evolve in the dark?

Through a multidisciplinary approach to understanding colour vision and animal behaviour, this study expects to fill a knowledge gap in visual neuroscience and ecology while adding to the understanding of how marine creatures see and interact. This should provide benefits in conservation and management strategies and may also inspire the development of new sensor technologies.Read moreRead less
Revealing the structure, evolution and sensitivity of symbioses in basal metazoa. This project will explore the complex interactions between each component of the sponge holobiont (virus, bacteria, sponge) during thermal stress. This will also provide the first molecular assessment of sponge viruses and provide insights into how sponges may adapt to a changing climate.
Understanding the ecological effects of genetic diversity: causes, consequences and relative importance. This project will examine the effect of genetic diversity on key demographic parameters (for example, population growth rates) for organisms from three groups, including a commercially important oyster. This project provides valuable information that can be used by managers of wild and cultivated populations to minimise impacts of human activities and maximise yields.
The functions of reef fish colour patterns: how did the coral trout get its spots? How did the coral trout get its spots? Why are some reef fish striped yellow and blue while others dress in pink and orange blotches? This project goes beyond just interpreting animal colours and uses a new approach to reveal the meanings of whole body patterns. Uniquely, it does so through the eyes of the fish themselves.
Evolution of the marsupial gut microbiome and adaptation to eucalypt toxins. Eucalyptus leaves comprise all or part of the diet of some marsupials including koalas. Gut microbiota assist in the ability of these folivores to tolerate eucalyptus toxins although present understanding of this process is rudimentary. This project aims to use culture-independent molecular methods to identify and characterise gut populations involved in phytochemical detoxification by comparative analysis with diprotod ....Evolution of the marsupial gut microbiome and adaptation to eucalypt toxins. Eucalyptus leaves comprise all or part of the diet of some marsupials including koalas. Gut microbiota assist in the ability of these folivores to tolerate eucalyptus toxins although present understanding of this process is rudimentary. This project aims to use culture-independent molecular methods to identify and characterise gut populations involved in phytochemical detoxification by comparative analysis with diprotodont relatives that are not capable of digesting eucalyptus leaves. This will highlight evolutionary convergence of gut microbiomes in toxic folivores and reveal mechanisms by which microorganisms respond to and metabolise eucalypt toxins. A broader evolutionary context of marsupial digestive function will assist in ongoing conservation efforts.Read moreRead less
Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and gene ....Illuminating the evolutionary history of Australia’s most iconic animals. This project aims to pinpoint the nature and timing of key steps in macropod history and to test how these link with major climatic and biotic changes. Macropods (kangaroos and relatives) are widely considered the marsupial equivalents to hoofed mammals on other continents, but we have a weaker understanding of how their evolution was shaped by environmental change. This project will combine palaeontology, anatomy and genetics to address questions such as how and why ancestral macropods descended from the trees and evolved bipedal hopping, and the upper size limits of the kangaroo “body plan”. This should improve our understanding of the long-term effects of climate change on marsupials, and provide a test of key placental-based evolutionary models.Read moreRead less
Who's calling? Understanding and exploiting signalling system ecology to improve success in trapping cane toads. This project has five major national and community benefits for Australia. It will: 1. provide a much-needed control option for a major pest, 2. actually remove many toads during the course of the study, through trapping at various locations around Australia, 3. support an Australian small business by providing research outcomes that will enable it to develop and market a highly desi ....Who's calling? Understanding and exploiting signalling system ecology to improve success in trapping cane toads. This project has five major national and community benefits for Australia. It will: 1. provide a much-needed control option for a major pest, 2. actually remove many toads during the course of the study, through trapping at various locations around Australia, 3. support an Australian small business by providing research outcomes that will enable it to develop and market a highly desired product, and 4. provide high level, postgraduate training in science. This project directly addresses the National Research Priority goal safeguarding Australia, protecting Australia from invasive … pests, because it will generate new technologies useful for controlling an invasive species.Read moreRead less
Peripheral isolates as hotbeds of adaptive diversity. This project uses cutting edge molecular technology and spatial analyses to predict the location of diversity relevant to managing the impact of climate change. Knowledge generated in this project will open the door to the informed use of genetic translocation in efforts to kerb expected biodiversity losses.
