Drivers of Habitat Selection by the Endangered Greater Caribbean Manatee in Coastal‐Marine Ecosystems

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Habitat selection is a fundamental aspect of animal movement and behaviour, involving strategies that influence population regulation, species interactions, community structure and the generation and preservation of biodiversity. The Greater Caribbean Manatee is a megaherbivorous aquatic mammal with high environmental plasticity, found in a ...

How to remove the brain of Amazonian manatee (Trichechus inunguis) calves preserving the skull for morphological analysis [PDF]

Acta Amazonica
Although there are several studies on the skull of Amazonian manatees (Trichechus inunguis) to better understand the anatomy, physiology, and behavior of these animals, the analysis of the brain has been often neglected.

Do Marine Mammals Diversify More Slowly Than Non‐Marine Mammals?

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Species richness is generally lower in marine than in terrestrial ecosystems, but the reasons behind this disparity remain unclear. This study examines whether marine mammals diversify at a slower pace than their non‐marine counterparts, aiming to shed light on the factors explaining potential diversification differences among them ...

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 ...
