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

United States Fish & Wildlife Service - Contract Research

Hawksbill turtles of the Ocean and Pacific Oceans

Indicative Funding: $10,000 over 1 year
Summary: Review of Literature on the populations of hawksbills in the Indian Ocean (Northeast, Northwest, Southeast, Southwest) and Pacific Oceans (East, North Central, South Central, Southwest, West Central, West Pacific/South East Asia) RMUs (2013-2020).

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)?
Investigators: Mark Hamann, Emily Webster and Stephanie Duce in collaboration with Colin Limpus and Takahiro Shimada (College of Science & Engineering, QLD Department of Environment and Heritage Protection and Australian Institute of Marine Science)
Keywords: Turtle; Tracking; Gladstone; Behaviour

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.

Australian Research Council - Linkage - Projects

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.
Investigators: Michael Rasheed, Rod Connolly, Mark Hamann, Peter Macreadie, Helene Marsh and Marcus Sheaves in collaboration with Megan Ellis (TropWATER, Griffith University, College of Science & Engineering, University of Technology, Sydney and Gladstone Ports Corporation)
