Summary
Pre-natal communication in adaptation to hot climate. This project aims to reveal how birds programme their offspring for a warming world, by communicating acoustically with their embryos. Most animals, including humans, can hear external sounds before birth, but it is not known what function this plays. An Australian bird calls to its eggs at high ambient temperatures, which alters nestling growth and survival. This project will show the physiological effects involved and the consequences for a ....Pre-natal communication in adaptation to hot climate. This project aims to reveal how birds programme their offspring for a warming world, by communicating acoustically with their embryos. Most animals, including humans, can hear external sounds before birth, but it is not known what function this plays. An Australian bird calls to its eggs at high ambient temperatures, which alters nestling growth and survival. This project will show the physiological effects involved and the consequences for adaptation to heat in wild birds. This project will elucidate whether the global reduction in animal body size is an adaptive response to rising temperatures, and research the therapeutic benefits of pre-natal sounds.Read moreRead less
Movement, migration and social networks in wild shark populations. Sharks are vital components of marine ecosystems and contribute significantly to ecotourism and fisheries. Due to their slow rate of growth and reproduction, sharks are susceptible to over exploitation. A lack of knowledge regarding their behaviour and movement patterns is a key impediment to effective management. This project aims to examine social interactions and migration patterns of Port Jackson sharks using a unique combina ....Movement, migration and social networks in wild shark populations. Sharks are vital components of marine ecosystems and contribute significantly to ecotourism and fisheries. Due to their slow rate of growth and reproduction, sharks are susceptible to over exploitation. A lack of knowledge regarding their behaviour and movement patterns is a key impediment to effective management. This project aims to examine social interactions and migration patterns of Port Jackson sharks using a unique combination of genetic techniques, novel acoustic tag technology, behavioural manipulations and modern social network analysis. Once verified, the approach developed can be applied to other marine predators of particular management concern. The data generated will directly inform fisheries and conservation management policy.Read moreRead less
Nutritional requirements of the critically endangered corroboree frog. This project aims to test the effect of dietary carotenoids on an extensive range of fitness-determining traits in the endangered southern corroboree frog. Unprecedented rates of species extinction have been reported for all vertebrates, with amphibians most severely affected. Captive breeding programs play a key role in amphibian conservation, yet there is a lack of knowledge regarding the nutritional requirements of threate ....Nutritional requirements of the critically endangered corroboree frog. This project aims to test the effect of dietary carotenoids on an extensive range of fitness-determining traits in the endangered southern corroboree frog. Unprecedented rates of species extinction have been reported for all vertebrates, with amphibians most severely affected. Captive breeding programs play a key role in amphibian conservation, yet there is a lack of knowledge regarding the nutritional requirements of threatened species. Manipulating captive nutrition is a cost-effective action that will permit recovery teams to more efficiently implement conservation actions. The findings will be of major benefit to amphibian conservation globally.Read moreRead less

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
Impacts of locust control pesticides on arid-zone fauna. Impacts of locust control pesticides on arid-zone fauna. This project aims to understand how different animals encounter pesticide in the landscape through quantifying residue deposition in arid grasslands and investigating how pesticides used to control locust plagues affect fauna.

This project aims to understand how different animals encounter pesticide in the landscape through quantifying residue deposition in arid grasslands and investigating how pesticides used to control locust plagues affect fauna. This project will investigate fenitrothion and fipronil, the main pesticides used in Australia for locust control. It will develop a deposition model for aerial pesticide spraying, determine the short-term effect of sprayed pesticides on the behaviour and condition of free-ranging target fauna that use the environment differently, and quantify the relative importance of dietary and non-dietary exposure routes to gauge the importance of animal behaviour on pesticide exposure. Anticipated outcomes are improved baseline assessments for locusticides.Read moreRead less

This project aims to address the unresolved evolutionary origins of bat echolocation. Using a unique combination of development, evolution and novel engineering testing, this project expects to generate new insights into how features of the skull have evolved to allow bats to use their senses to interact with the environment. Expected outcomes include the identification of skull features that are unique to echolocating bats and tests of how these relate to the frequency and detection range of sounds produced. Benefits include improved conservation planning for urban and rural bat populations, and potential commercial advances through engineering applications that mimic the biological process of echolocation.

This project aims to better understand how the beak and feather disease virus (BFDV) is assembled. The virus affects Australian native birds, which are currently endangered or critically endangered and has the potential to disrupt native ecosystems. By using interdisciplinary research, this project will generate fundamental knowledge by which BFDV protein complexes are formed. The intended outcomes of the project include the identification of key binding interfaces involved in viral formation processes. This information intends to guide cost-effective delivery of potential anti-viral options or vaccines for endangered Australian native parrots, and for use as a model to target other pathogenic DNA viruses of interest.Read moreRead less
Breeding echidnas in captivity. This project aims to provide novel insights into the cryptic and secretive mode of the reproduction of echidnas, and enable development of reliable methods for breeding them in captivity. There has not been a sustainable breeding program for echidnas in any zoo world-wide. This is needed because most studies on echidnas have all been field-based, and so not open to manipulation to answer key questions relevant to their conservation and survival.

This project aims to provide novel insights into the cryptic and secretive mode of the reproduction of echidnas, and enable development of reliable methods for breeding them in captivity. There has not been a sustainable breeding program for echidnas in any zoo world-wide. This is needed because most studies on echidnas have all been field-based, and so not open to manipulation to answer key questions relevant to their conservation and survival. Using novel scientific results on the short-beaked echidna, the project will provide new knowledge relevant to monotreme conservation, research and education, and enable the development of reliable methods for breeding the critically endangered, long-beaked echidna in captivity.Read moreRead less
Vulnerability of Australian bats to white-nose syndrome. Australia's unique wildlife is inherently at risk from invasive novel pathogens. White-nose syndrome is an emerging fungal disease that has decimated bat populations across North America.

Australia's unique wildlife is inherently at risk from invasive novel pathogens. White-nose syndrome is an emerging fungal disease that has decimated bat populations across North America. This fungal disease is likely to soon jump continents and also seriously threaten Australia's bat fauna. This project aims to quantify the risk of exposure to this fungus and understand the sensitivity of Australian bat populations to white-nose syndrome mortality. Expected outcomes include spatially-explicit, species-specific models of vulnerability to white-nose syndrome for bat populations across south-eastern Australia, essential for directing actions to prevent, detect and mitigate the impacts of this potentially catastrophic wildlife disease.Read moreRead less
