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.

Analysis of body condition indices reveals different ecotypes of the Antillean manatee
Scientific Reports, 2021 Assessing the body condition of wild animals is necessary to monitor the health of the population and is critical to defining a framework for conservation actions. Body condition indices (BCIs) are a non-invasive and relatively simple means to assess the
