Trophic cascades in Australian seagrasses: linking nutrients to survival and growth of commercially-important fishes. Despite its high conservation status and importance to commercial and recreational fisheries, seagrass is still declining in Australian waters. By investigating a trophic cascade that links nutrient pollution to the growth and survivorship of seagrass and commercially-important juvenile fishes, our study fills knowledge gaps crucial for improved future management of seagrass hab ....Trophic cascades in Australian seagrasses: linking nutrients to survival and growth of commercially-important fishes. Despite its high conservation status and importance to commercial and recreational fisheries, seagrass is still declining in Australian waters. By investigating a trophic cascade that links nutrient pollution to the growth and survivorship of seagrass and commercially-important juvenile fishes, our study fills knowledge gaps crucial for improved future management of seagrass habitats. The primary outcome of this study will be a model that can predict how changes in nutrient pollution will influence population dynamics of commercially-important fish species supported by seagrass. This information has, therefore, direct relevance to managers of estuarine and coastal environments at all levels of government - local, state and federal.Read moreRead less

This project will assess important biological parameters of shelf and slope ommastrephid squids. Lab based studies will explore age, growth, maturity rates and diet for the deepwater squid Todarodes filippovae. Cutting -edge telemetry technology (manual tracking, listening curtains and satellite pop-up tags) will assess movement, activity, metabolism and vertical migration of both T. filippovae in deep water and arrow squid (Nototodarus gouldi) on the shelf. A comprehensive understanding will be gained of the biology and lifestyle of these two key squid species that will be utilised by implementers of the South-east Regional Marine Plan, ecosystem modelers and resource managers.Read moreRead less
Population structure in the giant Australian cuttlefish - implications for management of a unique eco-tourism and fishery resource in regional Australia. A management strategy for the giant Australian cuttlefish in regional South Australia is required urgently because of potential conflict between ecotourism and fishery sectors. At present, development of a management strategy is stymied by lack of information on stock structure and movements.

A management strategy for the giant Australian cuttlefish in regional South Australia is required urgently because of potential conflict between ecotourism and fishery sectors. At present, development of a management strategy is stymied by lack of information on stock structure and movements. Analyses of variation in gene frequencies, morphometric and chemical trace element profiles in calcified structures among locations and years will enable the geographic extent of populations or stocks to be determined, including whether natal homing occurs. Such information is critical to sustainable management of the species and design of a marine protected area in the upper Spencer Gulf.Read moreRead less
Assessment of the Risks Posed to an Antarctic Keystone Species, Antarctic krill (Euphausia superba), Through Exposure to Persistent Organic Pollutants. POPs are subject to a global treaty seeking to reduce and eventually eliminate these chemicals from the environment.

POPs are subject to a global treaty seeking to reduce and eventually eliminate these chemicals from the environment. Inhibiting the development of effective intervention strategies is a lack of knowledge regarding biological dose-response and cause-effect relationships. The proposed study will develop multiple endpoint assays to investigate these species-specific relationships and undertake a multidisciplinary risk assessment of increasing POP levels to E. superba. The research will fulfil national treaty requirements and represents an excellent opportunity to advance the field of polar and marine POP ecotoxicology. Outcomes will be critical for the sustainable management of a commercial resource and a pressured keystone species. Read moreRead less
The diversity and assembly of optics in nature. Optics, such as the design of new coloured reflectors, is a research strength for Australia. A reason for this is the potential for application - optical devices can be found far and wide in our everyday lives, from security devices on banknotes (holograms), to computer monitors (LCDs). An interesting parallel exists in nature - animals possess similar optical devices to those we use. So it makes sense to examine the animals' devices in a search fo ....The diversity and assembly of optics in nature. Optics, such as the design of new coloured reflectors, is a research strength for Australia. A reason for this is the potential for application - optical devices can be found far and wide in our everyday lives, from security devices on banknotes (holograms), to computer monitors (LCDs). An interesting parallel exists in nature - animals possess similar optical devices to those we use. So it makes sense to examine the animals' devices in a search for new reflectors, and that's an aim of this project. And since reflectors are often difficult to make, why not let animals make reflectors for us? That is a further aim of this project. Soon we may have genetically-altered butterfly scales embedded in our credit cards that cannot be counterfeited.Read moreRead less
Ecological impacts of QX Oyster disease and its management strategies. QX disease is responsible for mass mortality of oysters, and, as a result, economic and job losses. QX disease also threatens ecosystem services provided by wild oysters, such as biodiversity enhancement and fish production. This project will provide estuarine managers with information about how proposed QX management solutions will impact wild oyster populations and vital ecosystem services. It will also contribute to traini ....Ecological impacts of QX Oyster disease and its management strategies. QX disease is responsible for mass mortality of oysters, and, as a result, economic and job losses. QX disease also threatens ecosystem services provided by wild oysters, such as biodiversity enhancement and fish production. This project will provide estuarine managers with information about how proposed QX management solutions will impact wild oyster populations and vital ecosystem services. It will also contribute to training of early career researchers in strategies to ensure the sustainable use of Australia's biodiversity. As QX outbreaks appear to be increasing, this research and training is urgently needed to underpin management to ensure long-term sustainability of valuable estuarine resources.Read moreRead less

Biodiversity planning in the urban fringe: multiple actors, multiple conservation actions, multiple uncertainties. Accelerating urbanisation in Australia is considered one of the greatest threats to biodiversity, with over 50% of threatened species occurring in urban fringe areas. Conservation planners in the urban fringe lack tools that can simultaneously prioritize multiple conservation actions by multiple actors and reconcile complicated tradeoffs. This project addresses the important gap bet ....Biodiversity planning in the urban fringe: multiple actors, multiple conservation actions, multiple uncertainties. Accelerating urbanisation in Australia is considered one of the greatest threats to biodiversity, with over 50% of threatened species occurring in urban fringe areas. Conservation planners in the urban fringe lack tools that can simultaneously prioritize multiple conservation actions by multiple actors and reconcile complicated tradeoffs. This project addresses the important gap between conservation theory and real world practice, providing tools for managers to develop optimal strategies given real-world constraints. It will result in better theories and models for designing and evaluating conservation policy and plans to ensure good biodiversity outcomes. Results will be generalisable to any complex conservation planning scenario.Read moreRead less
