Multi‐Scale Habitat Selection of Greater Caribbean Manatees in Sian Ka'an Biosphere Reserve, Mexico
Marine Mammal Science, Volume 42, Issue 1, January 2026.ABSTRACT Habitat selection describes population distribution as a function of environmental features. It is a fundamental process with primordial ecological and evolutionary implications. To accurately describe habitat selection, it is important to identify temporal and spatial scales perceived by the population and use these scales when modeling ...

Drone photogrammetry reveals contrasting body conditions of dugongs across the Indo‐Pacific
Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 701-718, December 2025.The monitoring of body condition has gained traction as a way to provide early warning signals of population decline, prompting conservation actions. However, the environmental and anthropogenic drivers of body condition variations are rarely investigated.
