Expanding the Toolbox: Mangrove Use by Spotted Eagle Rays (Aetobatus ocellatus) in the Maldives Revealed Through Drone‐Based Observation

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study reports the first scientific record of the spotted eagle ray Aetobatus ocellatus within a mangrove embayment in the Republic of the Maldives, documented through drone‐based observations. We observed four individuals, including one juvenile, that we recorded using an unmanned aerial vehicle (UAV), highlighting mangrove habitats as potential ...

Multi‐Metric Monitoring: Comparing Occupancy and Abundance Based Metric Sensitivity for Detecting Threatened Species Responses to Environmental Change

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Abundance and occupancy provide complementary but non‐equivalent signals of threatened species change. Here, their relationship was nonlinear and responses to environmental change were context dependent, showing that no single metric captures all population responses and that combining both can better inform conservation action under global change ...
