Testing metabolic theories in ecology. There are striking similarities in the way plants and animals take up and use energy (metabolism), despite enormous variation in size and life-style. This project will make the first experimental comparison of the predictions of the two major theories for these broad patterns. The results will significantly progress this controversial and exciting field.
Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes ....Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes. This project expects to generate new knowledge on the anatomy of the vertebrate brain with improved methods for reconstructing fossil brains to better understand our own neurological evolution. Expected outcomes include enhanced institutional collaborations within Australia, and between Australia, Canada and the USA.Read moreRead less
Functional links between estuaries and their catchments: How does land use change affect estuarine ecological and bio-geochemical function? Estuaries are iconic recreational areas of high ecological and socio-economic value. Estuarine health is strongly linked to the catchments that feed them, yet we have no detailed understanding of these links. This project will use a number of state of the art approaches to better understand how land use affects estuarine health.
Understanding snow gum dieback for effective and integrated management. The project leverages recent research and infrastructure investments and our determined and collaborative team as it aims to: 1) assess the future geography of snow gum dieback in the high country and identify priority locations for pro-active management, 2) quantify the impact of snow gums on high country water and carbon budgets and thus the socio- economic and biodiversity values, and 3) determine options for mitigation. ....Understanding snow gum dieback for effective and integrated management.

Dieback of our iconic snow gum forests is diminishing the ecological, hydrological and cultural values of the Australian Alps and will impact state and national water-supply and power-generation systems. Our research will inform Alps-wide management efforts designed for long-term success.Read moreRead less
The danger within: assessing the threats to an endangered finch from genetic incompatibility, limited dispersal and effective population size. The Gouldian finch has declined dramatically over the past half century and remains one of Australia's most threatened birds. This project will use some cutting edge genetic techniques to understand some of the processes that undermine the species' recovery and our ability to monitor current populations.
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.
Ecological role of sleep in maintaining optimal brain function in birds. This project aims to explain the function of sleep. Sleep is thought to maintain optimal brain functioning to support waking cognition. Nearly all sleep research is laboratory-based, which fails to realistically capture how animals benefit from sleep. Ecologists treat sleep as a simple behaviour, instead of as a heterogeneous neurophysiological state, while neuroscientists generally fail to appreciate the insights ecologica ....Ecological role of sleep in maintaining optimal brain function in birds. This project aims to explain the function of sleep. Sleep is thought to maintain optimal brain functioning to support waking cognition. Nearly all sleep research is laboratory-based, which fails to realistically capture how animals benefit from sleep. Ecologists treat sleep as a simple behaviour, instead of as a heterogeneous neurophysiological state, while neuroscientists generally fail to appreciate the insights ecological and evolutionary systems offer. This project adopts a cross-disciplinary approach, bringing together animal behaviour, ecology, evolution, anthropogenic disturbance and sleep neurophysiology. By doing so, the project will add a new dimension of understanding on the functions of sleep.Read moreRead less
Dining with Dasyurids: Using Nutritional Geometry to Improve Diets for Captive Breeding Programs. 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.

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
Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environmen ....Social and environmental selection on female ornaments and armaments. Darwin's theory of sexual selection is remarkably successful in explaining how elaborate signals evolved in male animals, but it is unclear whether similar processes drive the evolution of female signals. This project aims to conduct empirical and comparative tests of hypotheses for female trait elaboration, capitalising on inter- and intra-specific variation in female signal form, social organisation and signalling environments. The project could generate new insight into the processes that promote and constrain phenotypic diversity in nature.Read moreRead less
How different is different: highly contrasting colours in animal patterns. Red apples in green trees and blue berries on the ground create very different visual signals to animals. Furthermore, elaborate animal colour patterns have evolved to render them conspicuous or camouflaged against their background. Despite the ecological and evolutionary importance of animal colour patterns, little is known about how larger colour contrasts and complex patterns are perceived by animals. This project aim ....How different is different: highly contrasting colours in animal patterns. Red apples in green trees and blue berries on the ground create very different visual signals to animals. Furthermore, elaborate animal colour patterns have evolved to render them conspicuous or camouflaged against their background. Despite the ecological and evolutionary importance of animal colour patterns, little is known about how larger colour contrasts and complex patterns are perceived by animals. This project aims to fill this knowledge gap specifically it endeavours: to provide useful tools for behavioural ecologists and visual neuroscientists, and to understand for the first time the full gamut of colour signalling in both terrestrial and aquatic environments.Read moreRead less
