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.
Movement patterns and behavioural strategies of Estuarine Crocodiles: A long-term remote monitoring study using an underwater acoustic array. The on-going recovery of the estuarine crocodile population is creating a paradox for Australians. Although a salient species, an iconic animal, and a firm tourist attraction, estuarine crocodiles pose a significant risk to the public. Knowledge of where crocodiles go, what they do when they get there, and why they select particular habitats at certain tim ....Movement patterns and behavioural strategies of Estuarine Crocodiles: A long-term remote monitoring study using an underwater acoustic array. The on-going recovery of the estuarine crocodile population is creating a paradox for Australians. Although a salient species, an iconic animal, and a firm tourist attraction, estuarine crocodiles pose a significant risk to the public. Knowledge of where crocodiles go, what they do when they get there, and why they select particular habitats at certain times is critical for sustaining the Australian crocodile population, whilst ensuring public safety. This long term study will utilise the latest advancement in underwater acoustic technology to monitor the behavioural and physiological strategies used by estuarine crocodiles in occupying critical habitats, providing vital information for resource managers and policy makers.

Evolutionary roots of social bonds in female mammals. The social networks and friendships of wild female kangaroos and how these benefit individuals will be studied. This project will help us understand how the propensity of mammals to form friendships evolved; this understanding of the evolutionary roots of friendships will help in understanding why friendships affect peoples' health and mortality.
The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lac ....The effect of native invasions on Australian fisheries species. This project aims to forecast climate-related changes in the diversity, distribution and abundance of fisheries species. In a changing world where many people depend on oceans for food and livelihood, predicting the future distribution of fisheries species is a challenge. Native invasions and ocean warming are stressing inshore fisheries species, but rigorous empirical data and models that can reliably forecast these effects are lacking. This project intends to reveal the drivers of successful native invasions, evaluate their effect on fish diversity and productivity, and develop holistic models that forecast their effects on inshore fisheries species’ near-future distribution and stocks.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
Extreme acid tolerance: Overcoming the challenges of life at low pH. This project aims to investigate tolerance to low pH freshwaters, focusing on the mechanisms that underpin acid tolerance, physiological plasticity, the interactions between low pH and other environmental variables (e.g. temperature), and the costs and/or trade-offs to living in such physiologically challenging environments. Low pH waters are toxic to most animals, yet some freshwater vertebrates have managed to colonise some o ....Extreme acid tolerance: Overcoming the challenges of life at low pH. This project aims to investigate tolerance to low pH freshwaters, focusing on the mechanisms that underpin acid tolerance, physiological plasticity, the interactions between low pH and other environmental variables (e.g. temperature), and the costs and/or trade-offs to living in such physiologically challenging environments. Low pH waters are toxic to most animals, yet some freshwater vertebrates have managed to colonise some of the lowest pH environments on Earth. In our rapidly changing world, this study is expected to provide an important fundamental understanding of the capacity of some organisms to flourish at environmental extremes and their ability to respond to increased variability both within and between environmental stressors.Read moreRead less
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.
Solar radiation, coral bleaching and climate change. Corals reefs like the Great Barrier Reef (GBR) underpin approximately $2 billion annually in sustainable tourism and fisheries. Warming of Australia's tropical seas, however, has increased mass coral bleaching/mortality and is placing reefs like the GBR at increasing risk. Solar radiation (PAR, UVR) plays an important influence on the biological outcome of thermal stress. Understanding the role of solar radiation is critical if we are to unde ....Solar radiation, coral bleaching and climate change. Corals reefs like the Great Barrier Reef (GBR) underpin approximately $2 billion annually in sustainable tourism and fisheries. Warming of Australia's tropical seas, however, has increased mass coral bleaching/mortality and is placing reefs like the GBR at increasing risk. Solar radiation (PAR, UVR) plays an important influence on the biological outcome of thermal stress. Understanding the role of solar radiation is critical if we are to understand the changes that will occur on coral reefs as temperatures increase. This multidisciplinary international team will define and model the role of solar radiation on thermal stress at local, regional and global scales. Read moreRead less
The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use ....The role of early life history on the survival of coral reef fishes - opening the Black Box. A fundamental unanswered question in marine ecology and fisheries management is - what influences the number of individuals that survive the larval phase to join a reef population? Theoretical studies show that small changes in the quality of offspring can lead to large changes in the numbers surviving the larval phase. What aspects of offspring quality determine who survives is largely unknown. We use a multidisciplinary approach to explore what influences the quality of offspring spawned by adults, and whether offspring traits prior to or at hatching determine the identity of individuals that survive to join the reproductive population.Read moreRead less
Living in a changing climate: the impacts of temperature during aestivation on burrowing frogs. Although arid zones of Australia are characterised by extremes of temperature, little is known about the thermal ecology of frogs inhabiting these regions. This project will determine the effects of temperature on the physiology of an arid-adapted frog and determine whether likely increases in global temperatures will impact its survival.
