Cranial and chromosomal geographic variation in manatees (Mammalia: Sirenia: Trichechidae) with the description of the Antillean manatee karyotype in Brazil

Journal of Zoological Systematics and Evolutionary Research, 2016
We employed landmark-based 3D geometric morphometrics to assess cranial size and shape diversification in Trichechus manatus and T. inunguis to compare it with patterns among all manatee taxa (T. manatus latirostris, T. m. manatus, T. inunguis and T. senegalensis), and to analyse geographic variation within American manatee populations, using a sample ...

Prioritizing future evidence needs for marine and freshwater mammal conservation action [PDF]

Animal Conservation, Volume 28, Issue 4, Page 542-552, August 2025.
To improve conservation practice, decisions should be informed by the available evidence on the effectiveness of conservation actions. Here, we review the comprehensiveness of this evidence base for marine and freshwater mammals. We assess the taxonomic and geographic coverage of the evidence base, identify biases and suggest priorities for future ...

SITUACIÓN DE UNA POBLACIÓN AISLADA DE MANATÍES Trichechus manatus (Mammalia: Sirenia: Trichechidae) Y CONOCIMIENTO DE LA GENTE, EN UNA LAGUNA URBANA, EN TABASCO, MÉXICO

Ecosistemas y Recursos Agropecuarios, 2012
El manatí del Caribe (Trichechus manatus, Linnaeus 1758) se considera en peligro de extinción en México y a nivel internacional, debido a la fuerte disminución de sus poblaciones en el pasado y a la modificación de su hábitat. Tabasco constituye una de las tres regiones importantes de distribución de manatíes en México, pero existen múltiples factores ...

Neurocranial bones are key to untangling the sea cow evolutionary tree: osteology of the skull of Sobrarbesiren cardieli (Mammalia: Pan-Sirenia) [PDF]

, 2022
The pan-sirenian Bauplan is conservative, probably owing to the constraints of adaptation to an aquatic lifestyle. Gathering morphological data from extinct forms is complex, resulting in poorly resolved phylogenies for stem pan-sirenians.
