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.

Color Vision in the Manatee (Trichechus manatus)

open access: yesVision Research, 1996
Four manatees were trained to discriminate between a colored stimulus and a shade of gray in a two-fold simultaneous choice situation. The colors blue, green, red and blue-green were tested against shades of gray varying from low to high relative brightness. The animals distinguished both blue and green from a series of grays but failed to discriminate

Disseminated toxoplasmosis in Antillean manatees Trichechus manatus manatus from Puerto Rico [PDF]

open access: yesDiseases of Aquatic Organisms, 2012
Necropsies were conducted on 4 Antillean manatees Trichechus manatus manatus that were stranded in single events on the coastal beaches of Puerto Rico from August 2010 to August 2011. Three manatees were emaciated and the gastrointestinal tracts were devoid of digesta.

Distribution of the Antillean manatee (Trichecus manatus manatus) in the Alvarado Lagoon System (Veracruz, Mexico)

open access: yesCiencias Marinas, 2012
The Antillean manatee (Trichechus manatus manatus) is considered endangered in Mexico. Local extinctions have been documented in the northern Gulf of Mexico, and the only remaining population with a northern distribution is found in the Alvarado Lagoon ...

Disparity of turbinal bones in placental mammals. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Diet of the manatees (Trichechus manatus manatus) in Chetumal Bay, Mexico

open access: yesLatin American Journal of Aquatic Mammals, 2009
Manatees, as well as other sirenians, are aquatic, opportunistic herbivores. Knowledge of their diet is important to determine habitat requirements. This is the first study of manatee diet in Mexico. Our main objective was to identify the plant species eaten by manatees in Chetumal Bay, and to establish if diet composition varied by climatic season ...
