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 ...

Behavioral Lateralization in the Florida Manatee (Trichechus manatus latirostris) [PDF]

International Journal of Comparative Psychology, 2016
We examined side preferences in the Florida manatee (Trichechus manatus latirostris) through observations of limb use (right and left flipper) in 123 wild and 16 captive individuals. We also analyzed archival data on wild manatees to develop an index of boat-caused body scars to determine lateralization of evasive action.

An approach to modeling abundance of marine wildlife over space and time using unstructured aerial surveys

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
We present an approach for estimating wildlife abundance from unstructured aerial surveys. We combine a spatial model for count data with auxiliary information on detection probability. This framework is intended to be flexible, requiring lower survey costs and less computation time than other alternatives for estimating abundance.

Bioacoustic Classification of Antillean Manatee Vocalization Spectrograms Using Deep Convolutional Neural Networks

Applied Sciences, 2020
We evaluated the potential of using convolutional neural networks in classifying spectrograms of Antillean manatee (Trichechus manatus manatus) vocalizations. Spectrograms using binary, linear and logarithmic amplitude formats were considered.

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 ...
