Working with wind energy and forestry for effective eagle conservation. This project aims to reduce the impacts of wind turbines and disturbance from forestry activity on the Tasmanian wedge-tailed eagle. It will do this by understanding the flight behaviour, movements and mortality of eagles, and the behavioural responses of breeding birds to forestry-related disturbance. The project will build new knowledge and institutional partnerships that will be used to minimise impacts on the Tasmanian e ....Working with wind energy and forestry for effective eagle conservation. This project aims to reduce the impacts of wind turbines and disturbance from forestry activity on the Tasmanian wedge-tailed eagle. It will do this by understanding the flight behaviour, movements and mortality of eagles, and the behavioural responses of breeding birds to forestry-related disturbance. The project will build new knowledge and institutional partnerships that will be used to minimise impacts on the Tasmanian eagle population, and develop models for use in planning. This will safeguard Australia's largest eagle and improve the sustainability of energy and forest industries. This research will also provide a model for the resolution of similar problems elsewhere in the world.Read moreRead less
Choosing to persist: sexual selection in the wild. This project aims to investigate the role of sexual selection in maintaining healthy wild populations. The prevailing story of sexual selection, in which the sexes either compete for or choose the other sex, has been of extravagant ornaments and displays that drive species to extinction. However, an opposing story has emerged, with elaborate ornaments reflecting a healthy genome and sexual selection instead sweeping away damaging genetic mater ....Choosing to persist: sexual selection in the wild. This project aims to investigate the role of sexual selection in maintaining healthy wild populations. The prevailing story of sexual selection, in which the sexes either compete for or choose the other sex, has been of extravagant ornaments and displays that drive species to extinction. However, an opposing story has emerged, with elaborate ornaments reflecting a healthy genome and sexual selection instead sweeping away damaging genetic material. This project expects to generate new knowledge on the potential for sexual selection to remove harmful mutations in the wild. Expected outcomes include determining if sexual selection can help prevent extinction in wild populations, with direct benefits for conservation programs.Read moreRead less
Pheromone attenuation: signal perception in changing atmospheric landscapes. Insects use chemical signals, or pheromones, to communicate with conspecifics. To convey information, the pheromone molecules must pass through the atmosphere and physically interact with receptors, typically located on the antennae of the receiver. Pheromones, like other organic compounds, are degraded by ozone, UV light, and radicals. While we know that pheromone plumes attenuate through the dispersal of molecules, th ....Pheromone attenuation: signal perception in changing atmospheric landscapes. Insects use chemical signals, or pheromones, to communicate with conspecifics. To convey information, the pheromone molecules must pass through the atmosphere and physically interact with receptors, typically located on the antennae of the receiver. Pheromones, like other organic compounds, are degraded by ozone, UV light, and radicals. While we know that pheromone plumes attenuate through the dispersal of molecules, the additional impact of pheromone degradation has been ignored. Our project aims to highlight the significance of odour survival for insect chemical communication by examining how atmospheric conditions, including air pollution, affects signal integrity, antennal morphology and signal perception.Read moreRead less
Quantifying the threat posed by feral cats to Australian reptiles. This project aims to provide the first quantification of the impact of feral cats on Australian reptiles, the country’s most diverse vertebrate lineage. This project expects to provide crucial missing pieces of the puzzle by adopting an innovative behavioural approach to determine how cats hunt for lizards, and how lizards respond to cat predation risk.

This project aims to provide the first quantification of the impact of feral cats on Australian reptiles, the country’s most diverse vertebrate lineage. This project expects to provide crucial missing pieces of the puzzle by adopting an innovative behavioural approach to determine how cats hunt for lizards, and how lizards respond to cat predation risk. The expected outcomes are an improved understanding of the capacity of native lizards to recognise cats as predators and respond appropriately, and a determination of the magnitude of threat that cats pose to native lizards. Importantly, our study aims to trial management strategies to mitigate the impact of cat predation on native reptiles.Read moreRead less

Summary
Protecting prey from predators using sensory tactics. This project aims to develop new approaches to prevent the extinction of threatened native species from invasive predators, such as rats, pigs, cats and foxes. Many native species are hard to see but vulnerable to being found by predators with powerful senses of smell and hearing. By harnessing the sensory cues of prey that predators use when hunting, this project expects to discover olfactory and auditory techniques that prevent predators fi ....Protecting prey from predators using sensory tactics. This project aims to develop new approaches to prevent the extinction of threatened native species from invasive predators, such as rats, pigs, cats and foxes. Many native species are hard to see but vulnerable to being found by predators with powerful senses of smell and hearing. By harnessing the sensory cues of prey that predators use when hunting, this project expects to discover olfactory and auditory techniques that prevent predators finding threatened species. In doing so, the project intends to provide new perspectives on how animals find food using multiple senses, and lead the recovery of threatened species in areas where predators remain within Australia and globally.

Improving the anti-predator responses of native mammals . Predation by introduced cats and foxes causes extinction and decline in Australian mammals. Protecting threatened mammals inside fenced sanctuaries is effective but they can become overpopulated, inbred and more naive to predators over time. This leads to a dwindling hope of ever restoring them to their natural habitat. Previous research has shown that exposing threatened mammals to low levels of cat predation in large fenced paddocks i ....Improving the anti-predator responses of native mammals . Predation by introduced cats and foxes causes extinction and decline in Australian mammals. Protecting threatened mammals inside fenced sanctuaries is effective but they can become overpopulated, inbred and more naive to predators over time. This leads to a dwindling hope of ever restoring them to their natural habitat. Previous research has shown that exposing threatened mammals to low levels of cat predation in large fenced paddocks improves their anti-predator behaviour, changes their physical appearance and improves survival. This grant seeks to understand the mechanisms (genetic/learning) behind these changes in order to harness and upscale our results and facilitate co-existence between native mammals and introduced predators.

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
Manipulating foraging by mammalian herbivores with plant odours. This project aims to reveal how mammalian herbivores exploit leaf odour to detect plants while foraging.

This project aims to develop a global approach to synthesise global tracking datasets and deliver near real-time diagnostics on risks for marine megafauna at a global scale pushing forward a new frontier in dynamic marine spatial management to improve conservation. This project expects to increase our understanding of how marine megafauna movements vary with environmental changes and how much they overlap with threatening global human activities. Expected outcomes will demonstrate how big data in marine telemetry can be synthesised and translated into ecologically significant behaviours. This should provide significant benefits to address global scientific and societal problems highlighted in the Australian science and research priorities.Read moreRead less
Plasticity and the origins of family. This project aims to answer the question of how family life evolved. Humans and many animals live in stable family groups because of the benefits of cooperation. Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. ....Plasticity and the origins of family.

Surprisingly, we have a very poor understanding of how family living initially evolved. This project will experimentally determine how simple responses to environmental change have driven the evolution of family living and thereby refine theories for understanding social evolution more generally. This information will be useful to environmental policy makers that need to consider the role of environmental change in managing and conserving viable populations.Read moreRead less
