I am a PhD student within the Centre for Ecology and Conservation, working under the supervision of Professor Brendan Godley and Dr Annette Broderick. I am Brazilian and have worked with marine turtles in Brazil since 2007, having conducted both in-water research and also work on nesting beaches. My current research involves studying the ecology of Leatherback sea turtles in Brazil, through the use of diverse techniques such as satellite tracking, stable isotopes, sex ratios and population trends analysis.

Broad research specialisms:

  • Ecology
  • Conservation
  • Marine turtles
  • Spatial ecology
  • Population trends
  • Mark and recapture studies

Project Title: Spatial ecology, habitat use and threats to the Leatherback Sea Turtle (Dermochelys coriacea) population in Brazil.

Supervisors: Professor Brendan Godley and Dr Annette Broderick

Funding Body: Science Without Borders Programme, through CNPq (National Counsel of Technological and Scientific Development), Brazil, also in collaboration with Projeto TAMAR (The Brazilian Sea Turtle Conservation Programme)

Project Description:
The leatherback sea turtle population in Brazil is considered critically endangered, mainly due to their restricted distribution and small population size, which makes them highly vulnerable to threats such as incidental capture in fisheries, habitat destruction/alteration and climate change. The broad objective of this project is to utilise a range of techniques, including satellite telemetry, stable isotopes, the thermal profile of nesting beaches and nest counts to obtain a more complete knowledge of the spatial ecology, habitat use, population trends and threats to the leatherback turtles nesting in Brazil, hopefully contributing to achieve their effective conservation.
