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.
Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding ....Sensory strategies for protecting endangered sawfishes. The Gulf of Carpentaria is the last habitat worldwide containing sustainable populations of sawfish. Easily entangled in nets, the saw has reduced population numbers dramatically in Australia with all species now protected under the Australian Environment Protection and Biodiversity Conservation Act, including the Convention on International Trade in Endangered Species (CITES). This study will provide basic biological information on feeding, prey manipulation and the role of critical senses in the only captive population of sawfishes in Australia. Such knowledge will underpin the development and use of visual, chemical and/or magnetic repellents by fisherman that are still responsible for the loss of large numbers of sawfish as by-catch.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
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.
Testing the importance of large-scale climate factors to plant community assembly following land-use change. This project will examine the native plant species and functional diversity of Australia's rain forest communities to create a predictive framework of how plant communities recover following deforestation. Such a framework is key to focusing conservation efforts in degraded and multi-use landscapes.
