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
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
Effects of physical disturbance on kelp-dominated reef communities across a broad temperate-tropical transition zone. The outcomes of this project will improve the understanding of the interactions between physical disturbances, nutrient enrichment and climate change. This addresses the national research priority of an environmentally sustainable Australia (priority goals sustainable use of biodiversity and responding to climate changes) and will contribute directly to Australia's commitments on ....Effects of physical disturbance on kelp-dominated reef communities across a broad temperate-tropical transition zone.

Summary
A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the developme ....A high-resolution isotope facility for low cost analysis of water, plant, and soil/sediment samples to understand environmental change. The most significant environmental challenges facing Australia include ensuring sustainable management of our water resources and conservation of both terrestrial and marine biodiversity, particularly in the face of our changing climate and land-use. The new instruments will accelerate progress across a number of projects aimed at understanding the development of groundwater resources, the relative dependency of ecosystems on groundwater versus soil and surface water, and an assessment of the likely impacts of altered hydrology, especially dewatering and salinisation, on ecosystems. In addition, they will also be used to extend our knowledge of climate variability in the recent past and increase understanding of critical marine resources.Read moreRead less
