Current and recent Research Funding to JCU is shown by funding source and project.

Ecological Society of Australia - Holsworth Wildlife Research Endowment

Investigating the behavioural ecology of diving and feeding in a cryptic marine mammal: the Dugong

Indicative Funding: $5,920 over 1 year
Summary: As air-breathing, bottom-feeding marine mammals, dugongs must dive to survive and thrive. Quantifying the diving and feeding behaviours of dugongs in three dimensions is a missing link in the science basis for the conservation of this Vulnerable species. This project will use advanced sensing technology to understand how seagrass biomass and dugong activity and energetics influence their diving and feeding behaviors. The resultant improved fine-scale understanding of these behaviors will provide important new information about their risk from vessel strike and the potential energetic consequences of habitat loss associated with extreme weather events and human disturbance.

Australian Government Department of Agriculture, Water and the Environment - The Assessment of Marine Turtle Stocks at Great Risk from Climate Change

Marine turtles and climate change

Indicative Funding: $51,818
Summary: Climate change is a recognised threat impacting Australian marine turtle populations. It is most evident on nesting beaches through the influence of rising temperatures and sea levels. The Australian Government recognises the threat and lists it as one of the highest-level risks in the Recovery Plan for Marine Turtles in Australia. In response the Australian Government?s Department Agriculture Water and Environment developed an Approach to Market for provision of a synthesis and review of all information necessary to enable understanding of the risk and vulnerability of nesting turtles from each stock to climate change and to support adaptation planning. In response we propose the delivery of a systematic review of biophysical information and climate model outputs for all stocks of marine turtles in Australia. We are confident of successful delivery of the project based on our collective globally recognised reputation as experts in marine turtle biology and conservation and employment of a research assistant for the duration of the project. Our response details how we will deliver the project, potential risks and suggestions for the workshop, and the experience of our team.

Eco Logical Australia Pty Ltd - Research Grant

Green turtle satellite tracking data analysis and reporting

Indicative Funding: $60,000 over 2 years
Summary: The project aims to understand (2) the patterns of habitat use and home range of foraging green turtles in Port Curtis? (2) How green turtles use habitats located within and immediately adjacent to port infrastructure in the western and southern sections of the Port, such as jetties and navigation channels? And (3) What are the patterns of movement and foraging behaviour of green turtles that shift between inside and outside the Inner Port habitats (i.e. from Pelican Banks to offshore of Curtis Is)?

Eco Logical Australia Pty Ltd - Research Grant

Increase understanding of flatback turtle habitat use - using satellite telemetry

Indicative Funding: $98,000 over 3 years
Summary: In the Australian Government's Reef 2050 plan there are several key knowledge gaps mentioned for flatback turtles. Our research project aims to build upon, and add value to, existing datasets to complete these gaps in knowledge. We aim to (1) examine habitat use of flatback turtles breeding in the Broadsound region of Queensland (2) Assess inter-nesting habitat use of flatback turtles for multiple breeding sites in GBRWHA (3) Determine parrterns of migratory and foraging behaviour of flatback turtles. Our research outputs will be provided to Australian and State Government staff and industry bodies to improve management of threats to flatback turtles.

Ecological valuation tools to protect seagrass during coastal development

Indicative Funding: $490,000 over 4 years, in partnership with the Gladstone Ports Corporation Ltd ($450,000)
Summary: Seagrasses provide ecosystem services (fisheries, nutrient cycling, primary productivity) worth trillions of dollars, but this capacity is threatened by coastal development. In Australia, port developments are considered a major threat to seagrass ecosystems, but resource managers lack accurate information about their potential impacts and mitigation measures. Focussing on differences between shallow and deep seagrasses within the Great Barrier Reef, this project seeks to develop a world-first spatial valuation tool that will allow resource managers and policy makers to minimise impact of port development on seagrass ecosystems, thereby ensuring that Australia?s seagrasses continue to provide ecosystem services essential to our well-being.
