MOLECULAR IDENTIFICATION OF TWO SPECIES OF TREMATODE PARASITES OF AMERICAN MANATEES (TRICHECHUS MANATUS) AND THEIR POSSIBLE ROLE AS BIO-INDICATORS OF HOST DISTRIBUTION AND DIET.

Journal of Parasitology
Sirenians comprise manatees and dugongs, which host various parasites that cause little or no pathology. Parasitological studies have recommended using Chiorchis spp. as bio-indicators of population distribution.

Classification of Florida manatee (Trichechus manatus latirostris) vocalizations

The Journal of the Acoustical Society of America, 2020
The vocal repertoire for the Florida manatee is quantitatively categorized from a sample of 1114 calls recorded from 3 different manatee habitats in Florida. First, manatee vocalizations were categorized into five call categories based on visual inspection of spectrograms and following descriptions provided in previous studies.

Hematology of the West Indian Manatee (Trichechus manatus)

Veterinary Clinical Pathology, 1982
SummaryHemograms on blood obtained from 10 clinically normal West Indian Manatees (Trichechus manatus) were studied. The red cells were large and in lower number than in most terrestrial species. The manatee does not have a neutrophil as is present in most species, but it has a heterophil whose granules stain pink with the Wright‐Giemsa stain.The ...

Antillean manatee (Trichechus manatus manatus Linnaeus, 1758) Tongue Morphology and Adaptive Herbivorous Implications

Microscopy and Microanalysis, 2023
Abstract Morphological study of the tongue is an interesting way of understanding evolutionary processes associated with feeding habits. Therefore, the aim of the present study was to describe the tongue morphology of the Antillean manatee and to understand possible morphological relationships with its way of capturing food.

Conservation issues using discordant taxonomic and evolutionary units: a case study of the American manatee (Trichechus manatus, Sirenia)

Wildlife research (East Melbourne), 2021
. The delimitation of evolutionarily significant units (ESUs) frequently results in controversy, but prioritising populations with evolutionary independence is essential for effective in situ conservation management.

Trichechus manatus latirostris (Manatee)

1977
Lymphocyte cultures were used for these karyotypes which were kindly donated by Dr. D.A. Duffield, Los Angeles, California. They come from Florida manatees and pairing is arbitrary, following that of White et al. (1976). Only one previous manatee, T. inunguis has been studied with 2n=56 (Loughman et al., 1970).

Viral Papillomatosis in Florida Manatees (Trichechus manatus latirostris)

Experimental and Molecular Pathology, 2002
The Florida manatee (Trichechus manatus latirostris) is one of the most endangered marine mammals in American coastal waters. Naturally resistant to infectious disease, the manatee immune system appears highly developed to protect it against the harsh marine environment and the effects of human-related injury.

Status and conservation of manatees Trichechus manatus manatus in Costa Rica

Biological Conservation, 1995
Aerial and boat surveys and interviews of coastal residents of Costa Rica suggest that manatees Trichechus manatus manatus are rare, even in regions such as Tortuguero, where they were reported to be fairly numerous in the recent past. Causes of the apparent decline have been suggested by local residents to include illegal hunting, high levels of ...

ELECTROCARDIOGRAPHY IN TWO SUBSPECIES OF MANATEE (TRICHECHUS MANATUS LATIROSTRIS AND T. M. MANATUS)

Journal of Zoo and Wildlife Medicine, 2006
Electrocardiographic (ECG) measurements were recorded in two subspecies of awake, apparently healthy, wild manatees (Trichechus manatus latirostris and T. m. manatus) undergoing routine field examinations in Florida and Belize. Six unsedated juveniles (dependent and independent calves) and 6 adults were restrained in ventral recumbency for ECG ...
