About

Dr Takahiro Shimada is a post-doctoral research fellow at the College of Science and Engineering. He grew up in Japan, completed a BSc in Agriculture at Meiji University (2002), a Masters in Science at the University of Tokyo (2012), and a PhD at James Cook University (2016). He is specialised in movement ecology using telemetry (e.g. GPS, Argos, time-depth recorder, accelerometer) and molecular techniques (e.g. stable isotope). He is also a developer of the R package SDLfilter, which is designed to screen satellite-derived location data. Current focus of his research is spatial ecology and conservation of sea turtles.

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.
Investigators: Mark Hamann and Takahiro Shimada in collaboration with Colin Limpus (College of Science & Engineering, Australian Government Department of Agriculture and Water and the Environment)

Satellite tracking of marine turtles from Raine island

Indicative Funding: $131,252 over 2 years
Summary: This project will investigate the temporal and spatial distribution of habitat use and behaviour for adult female green turtles that breed at Raine Island and will provide valuable information to the Raine Island Recovery Project to impelemnt management actions at Raine Island.
