Drivers of reef shark abundance and spatial distribution across an oceanic atoll

With Danielle Robinson, Newcastle University

One-quarter of the world’s sharks are threatened with extinction. A better understanding of shark abundance and their key environmental drivers is urgently needed to inform spatial management plans. Using baited remote underwater video systems (BRUVS) and dive surveys this study assessed patterns in shark abundance and spatial distribution across a Maldivian Atoll. In total 198 sharks from eight species were recorded. Prey biomass was found to have the greatest effect on abundance supporting the need for ecosystem-level conservation measures on coral reefs to support the conservation and recovery of shark populations.

Danielle is a third-year PhD student at Newcastle University. The goal of her research is to assess coral reef sharks, understand the local impacts of shark conservation on local stakeholders and inform future conservation actions.
