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.

Learning capacities and welfare in an Antillean manatee, Trichechus manatus manatus [PDF]

Comptes Rendus Biologies, 2020
Studies on the cognitive abilities of manatees are limited despite their importance for the environmental enrichment and welfare of individuals in captivity and the understanding of manatee behaviour in the wild.

First Description of a Satellite DNA in Manatees’ Centromeric Regions

Frontiers in Genetics, 2021
Trichechus manatus and Trichechus inunguis are the two Sirenia species that occur in the Americas. Despite their increasing extinction risk, many aspects of their biology remain understudied, including the repetitive DNA fraction of their genomes.

Vocalizations of wild West Indian manatee vary across subspecies and geographic location

Scientific Reports, 2023
Geographic variation in the vocal behavior of manatees has been reported but is largely unexplored. Vocalizations of wild West Indian manatees (Trichechus manatus) were recorded with hydrophones in Florida from Florida manatees (Trichechus manatus ...
