Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume ....Effects of river plumes on nearshore ecosystems: organic matter flows and food web consequences. River plumes may subsidize nearshore food webs by exporting land-derived material and by stimulating marine phytoplankton production via nutrient delivery. Whereas previous documentation of the biological responses to plumes has been mostly limited to large rivers and to primary production, this project targets small systems that discharge directly onto open coasts, and focuses on the fate of plume material. Work on carbon pathways will centre on pelagic and benthic food chains associated with plumes, and will also test whether nearshore waters and sandy beaches are coupled via onshore advection of plume material.Read moreRead less
New approaches for protecting stream health in temperate Australia: Devising nutrient and salinity guidelines using diatoms. Salinity and nutrient enrichment are the most significant forms of water quality degradation in Australian lowland rivers. This project will identify the biological effect of the water quality pollution and develop new methods for its assessment. Most importantly, through the identification of water quality "thresholds" which result in reduced biodiversity, better guidelin ....New approaches for protecting stream health in temperate Australia: Devising nutrient and salinity guidelines using diatoms.

An integrated examination of the drivers of movements of large filter feeding organisms of high ecotourism value: a case study. This aim is to define key drivers behind movements of large filter-feeding organisms, using the manta ray as a model system. As dive eco-tourism often depends on the presence of such charismatic filter-feeding animals, an understanding of why animals occupy particular sites at particular times is important, especially in the face of climate change.
Effect of deep-sea drilling on sustainability of deep-sea ecosystems. Offshore oil and gas production makes a significant contribution to the Australian economy and enhances our energy security. Australia's vast deep-sea reserves of hydrocarbons lie on the NW Shelf and in Bass Strait, ecological 'hot spots' that are extremely vulnerable to the impact of exploration, extraction and production. Using deep-sea equipment, we will conduct the field experiments that are essential to understanding the ....Effect of deep-sea drilling on sustainability of deep-sea ecosystems. Offshore oil and gas production makes a significant contribution to the Australian economy and enhances our energy security. Australia's vast deep-sea reserves of hydrocarbons lie on the NW Shelf and in Bass Strait, ecological 'hot spots' that are extremely vulnerable to the impact of exploration, extraction and production. Using deep-sea equipment, we will conduct the field experiments that are essential to understanding these ecosystems and the impact of deep-sea structures. Our advances will produce data and develop methodologies that will make Australia a world leader in reconciling our deep-sea energy and environmental needs.Read moreRead less
Small vertebrates from the Albian-Cenomanian of Queensland - testing hypotheses of provincialism among Australia's mid-Cretaceous dinosaur faunas. This project will add to our knowledge of Australian dinosaurs and the world they inhabited. Dinosaurs are often the means through which many people, especially children, are introduced to science. This project has the potential to greatly enhance this attraction to science, using the results of research on Australian dinosaurs. It has direct links wi ....Small vertebrates from the Albian-Cenomanian of Queensland - testing hypotheses of provincialism among Australia's mid-Cretaceous dinosaur faunas. This project will add to our knowledge of Australian dinosaurs and the world they inhabited. Dinosaurs are often the means through which many people, especially children, are introduced to science. This project has the potential to greatly enhance this attraction to science, using the results of research on Australian dinosaurs. It has direct links with a number of national and international museum exhibitions, and in western Queensland the results will be incorporated into a newly developed regional interpretive centre in Isisford. The enormous social and economic benefits linked to this initiative will open up numerous opportunities for local businesses, and increase the appreciation for science and exploration in outback areas.Read moreRead less

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.

Do artificial structures enhance the spread of exotic marine invertebrates in NSW estuaries? This project will investigate whether artificial structures in estuaries enhance the spread of exotic marine invertebrates and will examine the impacts of exotic species on rocky reef species. The introduction of exotic species is a significant threat to native biodiversity, second only to habitat destruction. These two threats are coincident in urbanised estuaries. This project will also provide infor ....Do artificial structures enhance the spread of exotic marine invertebrates in NSW estuaries? This project will investigate whether artificial structures in estuaries enhance the spread of exotic marine invertebrates and will examine the impacts of exotic species on rocky reef species. The introduction of exotic species is a significant threat to native biodiversity, second only to habitat destruction. These two threats are coincident in urbanised estuaries. This project will also provide information about the possible roles of different types of boating activity in transporting exotic species. Research on the role of artificial structures in invasions has not been done anywhere in the world and is essential if we are to understand, manage and ameliorate the threats of exotic species.Read moreRead less
The recovery of seagrass beds: the role of catchments and options for management responses. Seagrass beds once dominated tidal flats but are disappearing at an increasing rate due to human actions, both in Australia and around the world. This project will develop an understanding of the processes that cause these losses, the factors that prevent seagrass-bed re-establishment, and provide a framework for evaluating alternative management options.

This project aims to facilitate sustainable development in a fast-growing coastal region (Peel-Harvey, south-western Australia). By exploiting 30+ year data sets for this catchment-estuary system and integrating ecological, hydrological, biogeochemical, modelling and socio-economic expertise, this project seeks to link primary catchment drivers to estuarine health response (up to higher fauna), quantify estuarine ecological health and ecosystem services under historical and future scenarios, and test resilience across the human–natural system. Envisaged outcomes include evidence-based catchment planning solutions that optimise trade-offs between socio-economic development goals and minimal downstream impacts on estuarine health.Read moreRead less
