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

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

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

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.
