Phylogeography, phylogeny and hybridization in trichechid sirenians: Implications for manatee conservation
The three living species of manatees, West Indian (Trichechus manatus), Amazonian (Trichechus inunguis) and West African (Trichechus senegalensis), are distributed across the shallow tropical and subtropical waters of America and the western coast of Africa. We have sequenced the mitochondrial DNA control region in 330 Trichechus to compare their phylogeographic patterns. In T. manatus we observed

G-banded karotype and ideogram for the critically endangered North Atlantic right whale (Eubalanea glacialis)
Published cytogenetic data for extant cetacean species remain incomplete. In a review of the literature, we found karyotypic information for 6 of the 13 tentatively recognized species of the suborder Mysticeti (baleen whales). Among those yet to be described is the critically endangered North Atlantic right whale (Eubalaena glacialis). Herein, we describe and propose a first-generation G-banded ka

Electrocardiography in two subspecies of manatee (Trichechus manatus latirostris and Trichechus manatus manatus)
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 measurements. Six lead ECGs were recorded for all mana

Comparison of methods used to diagnose generalized inflammatory disease in manatees (Trichechus manatus latirostris)
Manatees (Trichechus manatus latirostris) are afflicted with inflammatory and infectious disease secondary to human interaction, such as boat strike and entanglement, as well as “cold stress syndrome” and pneumonia. White-blood-cell count and fever, primary indicators of systemic inflammation in most species, are insensitive in diagnosing inflammatory disease in manatees. Acute phase-response prot

Morphometry, gross morphology and available histopathology in North Atlantic right whale (Eubalaena glacialis) mortalities (1970 to 2002)
Fifty-four right whale mortalities have been reported from between Florida, USA and the Canadian Maritimes from 1970 to 2002. Thirty of those animals were examined: 18 adults and juveniles, and 12 calves. Morphometric data are presented such that prediction of body weight is possible if the age, or one or more measurements are known. Calves grew approximately linearly in their first year. Total le

Molecular identification of a papilloma virus from cutaneous lesions of captive and free-ranging Florida manatees
Cutaneous papillomatous lesions were biopsied from three captive Florida manatees (Trichechus manatus latirostris) at Homosassa Springs State Wildlife Park (HSSWP), Homosassa, Florida, USA, and from six free-ranging Florida manatees from Crystal and Homosassa rivers, Florida. Total DNA extracted from these lesions was assayed for the presence of papilloma virus genomes using the polymerase chain r

Manatees as sentinels of marine ecosystem health: are they the 2000-pound canaries?
The order Sirenia is represented by three species of manatees and one species of dugong distributed in tropical and subtropical regions of the world and considered vulnerable to extinction. The sentinel species concept is useful to identify indicators of the environment and may reflect the quality of health in marine ecosystems. The single species approach to evaluate ecological health may provide

Seasonal movements, migratory behavior, and site fidelity of West Indian manatees along the Atlantic coast of the United States
The West Indian manatee (Trichechus manatus) is endangered by human activities throughout its range, including the U.S. Atlantic coast where habitat degradation from coastal development and manatee deaths from watercraft collisions have been particularly severe. We radio-tagged and tracked 78 manatees along the east coast of Florida and Georgia over a 12-year period (1986-1998). Our goals were to

Echeneid-sirenian associations, with information on sharksucker diet
Association of the sharksucker Echeneis naucrates and whitefin sharksucker E. neucratoides with the West Indian manatee Trichechus manatus and the dugong Dugong dugon is presented and discussed. Alimentary tract-content analysis and field observations suggest that coprophagy (feeding on host faecal material) may be the primary food source for echeneids associated with sirenian hosts.
