Karyotypical Confirmation of Natural Hybridization between Two Manatee Species, Trichechus manatus and Trichechus inunguis

open access: yesLife, 2022
Two species of manatees are found in Northern Brazil—the Antillean manatee (Trichechus manatus), which is found along the coast from Florida to Northeastern Brazil, and the Amazonian manatee (Trichechus inunguis), endemic to the Amazon drainage basin ...

Phylogeography and sex-biased dispersal across riverine manatee populations (Trichechus inunguis and Trichechus manatus) in South America. [PDF]

open access: yesPLoS ONE, 2012
Phylogeographic patterns and sex-biased dispersal were studied in riverine populations of West Indian (Trichechus manatus) and Amazonian manatees (T.

Using transfer learning with a convolutional neural network to detect African manatee (Trichechus senegalensis) vocalizations [PDF]

open access: yesJASA Express Letters, 2022
African manatees (Trichechus senegalensis) are vulnerable, understudied, and difficult to detect. Areas where African manatees are found were acoustically sampled and deep learning techniques were used to develop the first African manatee vocalization ...

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

open access: yesScientific 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 ...

First Description of a Satellite DNA in Manatees’ Centromeric Regions

open access: yesFrontiers 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.

Ancestral chromosomal signatures of Paenungulata (Afroteria) reveal the karyotype of Amazonian manatee (Trichechus inunguis, Sirenia: Trichechidae) as the oldest among American manatees

open access: yesBMC Genomics, 2023
Background Chromosomal painting in manatees has clarified questions about the rapid evolution of sirenians within the Paenungulata clade. Further cytogenetic studies in Afrotherian species may provide information about their evolutionary dynamics ...

Colonizadores portugueses, tartarugas e peixes-boi: uma história da busca por carne, gordura e combustível na Amazônia do século XVIII

open access: yesDiálogos, 2017
Na Amazônia, os colonizadores portugueses consumiam a carne e gordura de peixes-boi (Trichechus inunguis e Trichechus manatus) e tartarugas-da-Amazônia (Podocmenis expansa).

Placentation in the Amazonian manatee (Trichechus inunguis) [PDF]

open access: yesReproduction, Fertility and Development, 2008
Evidence from several sources supports a close phylogenetic relationship between elephants and sirenians. To explore whether this was reflected in similar placentation, we examined eight delivered placentae from the Amazonian manatee using light microscopy and immunohistochemistry.
