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
Understanding and reversing the habitat shifts that have endangered the broad-headed snake. Extinction rates for vertebrate species are higher in southern Australia than almost anywhere else in the world, and saving endangered taxa is critical to biodiversity conservation. To do this effectively, researchers need to understand the processes that threaten wild populations, and to develop novel solutions to those problems in close collaboration with wildlife management authorities and other stake ....Understanding and reversing the habitat shifts that have endangered the broad-headed snake. Extinction rates for vertebrate species are higher in southern Australia than almost anywhere else in the world, and saving endangered taxa is critical to biodiversity conservation. To do this effectively, researchers need to understand the processes that threaten wild populations, and to develop novel solutions to those problems in close collaboration with wildlife management authorities and other stakeholders. This project will build such an understanding and collaboration, focusing on an endangered snake species. We propose ambitious landscape-scale field experiments that will simultaneously test hypotheses on threatening processes, and restore habitat quality to reverse population declines.Read moreRead less
Forecasting change in subtidal habitats: connecting local pollution with global climate in temperate Australia. The current narrow focus of management on local and contemporary environmental conditions (e.g. water quality) has indeterminate outcomes in the face of climate change. This proposal seeks to forecast marine habitats under realistic scenarios of climate change and continuing local population growth and activity. This information provides managers with information needed to understand t ....Forecasting change in subtidal habitats: connecting local pollution with global climate in temperate Australia. The current narrow focus of management on local and contemporary environmental conditions (e.g. water quality) has indeterminate outcomes in the face of climate change. This proposal seeks to forecast marine habitats under realistic scenarios of climate change and continuing local population growth and activity. This information provides managers with information needed to understand the consequences of current policy and debates about its improvement.Read moreRead less
Assessing the benefits of closed fishing areas for spawning aggregations and egg production for coral trout. Coral trout is a valuable finfish species that inhabits coral reef systems in Australia. Like most other finfish species, coral trout is managed mainly through catch and size limits. However, closed fishing areas also provide a degree of protection from exploitation. Worldwide, closed fishing areas have been shown to provide larger and more fish within their boundaries. At present, there ....Assessing the benefits of closed fishing areas for spawning aggregations and egg production for coral trout. Coral trout is a valuable finfish species that inhabits coral reef systems in Australia. Like most other finfish species, coral trout is managed mainly through catch and size limits. However, closed fishing areas also provide a degree of protection from exploitation. Worldwide, closed fishing areas have been shown to provide larger and more fish within their boundaries. At present, there are limited empirical data to show that they provide benefits to fish stocks. This project aims to examine whether closed fishing areas provide a benefit to coral trout at the Abrolhos Islands, Western Australia.Read moreRead less
Managing Australia's unique south coast. Innovative coastal management based on sound ecological understanding is a pressing issue in state and federal government. A federal initiative seeks integration of marine protected areas with other spatial arrangements for conservation of biodiversity. This proposal will inform the forthcoming selection of marine protected areas in South Australia. Significantly, it assesses whether adjacent land-use (natural vegetation, urbanisation, agriculture) can ....Managing Australia's unique south coast. Innovative coastal management based on sound ecological understanding is a pressing issue in state and federal government. A federal initiative seeks integration of marine protected areas with other spatial arrangements for conservation of biodiversity. This proposal will inform the forthcoming selection of marine protected areas in South Australia. Significantly, it assesses whether adjacent land-use (natural vegetation, urbanisation, agriculture) can enhance or compromise the utility of marine protected areas as a biodiversity repository.

Tracking squids from embryos to adults - novel approaches and new directions. Cutting edge acoustic tracking technology, combined with traditional tagging techniques and novel applications of trace element analysis, will allow for the life cycle of squid to be tracked through space and time - from embryonic stages through to spawning adults. Southern calamary earbones will be examined for evidence of elemental 'fingerprints' that reveal where they came from as hatchlings. This combined with trac ....Tracking squids from embryos to adults - novel approaches and new directions. Cutting edge acoustic tracking technology, combined with traditional tagging techniques and novel applications of trace element analysis, will allow for the life cycle of squid to be tracked through space and time - from embryonic stages through to spawning adults. Southern calamary earbones will be examined for evidence of elemental 'fingerprints' that reveal where they came from as hatchlings. This combined with tracking squid in Australia's biggest marine acoustic listening grid, will allow unprecedented resolution of squid life cycles. Commercial, recreational and managerial sectors are collaborating with this research to ensure sustainable management of this commercially important and ecologically crucial species.
