Lucien Besnard: Mercury isotope clocks predict coastal residency and migration timing of hammerhead sharks

Shortlisted for the 2023 Southwood Prize Lucien Besnard reflects on how he and colleagues used mercury isotopes, within the framework of isotopic clocks, to provide a more precise assessment of hammerhead shark movement. As a result, this method may be used as a complementary tool for stock management through predicting the timing of animal migration – a key aspect in the conservation of marine taxa. … Continue reading Lucien Besnard: Mercury isotope clocks predict coastal residency and migration timing of hammerhead sharks

How can movement ecology support marine protected areas in preventing illegal fishing?

In their recently published work, David Jacoby and colleagues combine long-term shark tracking data with that of enforcement patrols to see how behaviour can influence the vulnerability of marine life to illegal fishing in one of the world’s largest marine protected areas.
