Fig. 1: Impact of environmental stress on shark space use and residency.
From: Environmental stress reduces shark residency to coral reefs

Temporal trends in combined environmental stress exposure (SE) index experienced by coral reefs in the northern atolls of the Chagos Archipelago during a strong El Niño ‘episode’ and weaker El Niño ‘conditions’ (A). Grey reef shark residency (blue trend line) during the same period (Feb 2013–Feb 2021) and temporal changes in area use (km2) measured as the 50% (yellow), 75% (green) and 95% (pink) kernel utilisation estimation (KUD) (B).
