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
Metapopulation dynamics of coral communities on the Great Barrier Reef. Mathematical models for the dynamics of coral metapopulations on the Great Barrier Reef will be formulated and parameterised. Analysis of the models will focus on how the effects of competition between corals with different growth forms are influenced by other processes that generate spatial and temporal environmental variation. The project aims to understand how these factors influence the maintenance of high diversity in ....Metapopulation dynamics of coral communities on the Great Barrier Reef. Mathematical models for the dynamics of coral metapopulations on the Great Barrier Reef will be formulated and parameterised. Analysis of the models will focus on how the effects of competition between corals with different growth forms are influenced by other processes that generate spatial and temporal environmental variation. The project aims to understand how these factors influence the maintenance of high diversity in coral communities. It will also provide a modelling framework for predicting how that diversity will be affected by long-term environmental changes, making an important contribution to conservation and management of the Great Barrier Reef.Read moreRead less
Biodiversity of coral reefs. An international team will provide the first robust measures of the biodiversity, abundance and functional roles of key coral reef species at a global scale.

This research will cement Australia's leading contribution to coral reef science, and will guide the management, sustainable use and conservation of coral reef biodiversity across international boundaries.Read moreRead less
Ecological consequences of global warming: predicting effects on biodiversity on intertidal assemblages on the east coast of Australia. Understanding what conserves biodiversity is a crucial challenge for Australian science. This research will provide critical information on the consequences of global climatic change: southerly shifts in distributions of animals due to rising temperatures; vertical shifts due to rising sea level and changes in amounts of food for grazing species. This informatio ....Ecological consequences of global warming: predicting effects on biodiversity on intertidal assemblages on the east coast of Australia. Understanding what conserves biodiversity is a crucial challenge for Australian science. This research will provide critical information on the consequences of global climatic change: southerly shifts in distributions of animals due to rising temperatures; vertical shifts due to rising sea level and changes in amounts of food for grazing species. This information will underpin the future management of conservation and will improve understanding on issues such as how and why species are able to invade new areas, the effects on the resident species and how species change distribution in relation to the availability of specific needs for habitat.Read moreRead less
Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mech ....Long-term natural ecological consequences of disturbance on coral reefs: the benthic foraminifera perspective. The tropical coastline of Australia encompasses world-renowned coral reefs (Great Barrier Reef and Ningaloo Marine Park). Even these reefs are not pristine and are increasingly susceptible to disturbance from human impact. The long-term ecological effects of disturbance on reef communities cannot be experimentally determined; but natural experiments from the fossil record provide mechanisms to ensure that managers of Australia's reefs have critical information on how past disturbance frequency and intensity has affected coral reef communities. This information will help ensure the continuation of ecosystem goods and services from Australia's high diversity coral reefs.Read moreRead less
