Refining the ecological role of stingrays in coral reef ecosystems

Briefly describe your personal background
please use the 3rd person Ana completed her BSc. in Biological Sciences (2012) and MSc. in Biodiversity and Conservation at the Universidade Federal do Maranhão, Brazil. During her masters, she developed a research project focusing on the use of fisher and trader knowledge to describe the shark catch, produce a supply chain and evaluate perceptions regarding the regional conservation status of shark species in Northeastern Brazil.

Refining the ecological role of stingrays in coral reef ecosystems

2015 to 2019

Project Description

Project Description Briefly describe what the main aims of your project were (Please use the third person) Ana is developing a research project that aims to examine the role juvenile stingrays’ play in coral reef ecosystems and how important these ecosystems are to their populations.

Project Importance

Project Importance Briefly state why your project is important (Please use the third person) Stingrays are facing a range of threats, with several species at risk. They are increasingly taken by artisanal and industrial fisheries around the world, which have contributed to population declines. Other factors, such as habitat loss and climate change, also negatively affect stingray populations. However, the ability to effectively manage and conserve stingrays have been affected by a lack of knowledge on their biology and ecology. Ana’s research aims to fill some of the essential knowledge gaps in stingray biology, ecology and habitat requirements for survival.

Project Methods

Project Methods Briefly describe how you carried out your project, what methods did you use? (Please use the third person) To answer these questions, Ana is integrating acoustic and GPS telemetry to assess juvenile stingray movement patterns and habitat use. In addition, Ana is using stable isotope analysis and non-lethal gastric lavages to evaluate juvenile stingrays and sharks trophic roles at Orpheus Island.
