Abstract Information from 15 satellite‐tracked Antillean manatees ( Trichechus manatus ) was analyzed in order to assess individual movements, home ranges, and high‐use areas for conservation decisions. Manatees were captured Chetumal Bay, Mexico, tagged with Argos‐monitored satellite transmitters. Location of the physical characteristics assessed describe habitat properties. Most traveled freshwater sources. The Maximum Area Size MAS each manatee determined using observation‐area method....
Manatees, as well other sirenians, are aquatic, opportunistic herbivores. Knowledge of their diet is important to determine habitat requirements. This the first study manatee in México. Our main objective was identify plant species eaten by manatees Chetumal Bay, and establish if composition varied climatic season, sex or age class. We compared epidermal fragments found feces with histological descriptions permanent collections suspected plants algae. Thirty-six fecal samples nine tract...
Abstract Assessing the body condition of wild animals is necessary to monitor health population and critical defining a framework for conservation actions. Body indices (BCIs) are non-invasive relatively simple means assess individual animals, useful addressing wide variety ecological, behavioral, management questions. The Antillean manatee ( Trichechus manatus ) an endangered subspecies West Indian manatee, facing threats from mostly human-related origins. Our objective was define specific...
The tanaidaceans are among the most conspicuous and ecologically relevant benthic microcrustaceans in marine realm but there only a few records of species tanaids associated with other organisms. During long-term survey on biology distribution Caribbean manatee Trichechus manatus Linnaeus Mexican waters, parasites epibionts were collected from 47 individuals that captured for tagging two bay systems. Well-established epibiotic communities tanaidacean Hexapleomera robusta (Moore) found eight...

The harpacticoid copepod Balaenophilus manatorum (Ortíz, Lalana and Torres, 1992 Ortíz, M, Lalana, R Torres-Fundora, O. 1992. Un nuevo género y una nueva especie de copépodo Harpacticoida asociada al manatí Trichechus manatus en aguas cubanas. Rev Invest Marinas La Habana., 13: 117–127. [Google Scholar]) was originally described based on a few specimens collected from single manatee in Cuba. Since its description it has been recorded exclusively as symbiont of sea turtles worldwide; there...
Understanding predator–prey relationships is critical in ecology, but relatively challenging when investigating elusive marine megafauna. In this study, we document the presence of shark-inflicted injuries on coastal bottlenose dolphins (Tursiops truncatus) Mesoamerican Reef System using photo-identification methods. We analyzed data from a total 533 photo-identified Mexico (Ascención Bay, Espíritu Santo and Chetumal Bay), Belize (Turneffe Atoll, Drowned Cayes, Barrier Reef, Placencia),...
Los manatíes (Trichechus manatus manatus) son mamíferos herbívoros y de hábitos oportunistas, se alimentan casi 60 especies plantas. El objetivo este trabajo fue identificar los elementos la dieta del manatí por medio análisis heces en dos sitios México (Jonuta, Tabasco Bahía Ascensión, Quintana Roo) uno Belice (Southern Lagoon). Las muestras provienen vida libre cautiverio que fueron capturados temporalmente para muestreo evaluación su salud durante el período 2004-2006. Un total 24...
Body size determines many physiological and ecological variables; however, there are few studies on this parameter for the Antillean manatee (Trichechus manatus manatus). We studied an osteological collection databases of manatees in Mexico to infer body measurements determine mass (BM)/body length (BL) relationship. The sample included 165 specimens: skulls (n=60), necropsies (n=51), individuals captured health assessment purposes (n=54). Specific regression equations estimating BM were...

Abstract Strandings and opportunistic sightings represent an invaluable source of information on cetacean’s biodiversity in the Mexican Caribbean. Here, we document stranding rescue two pantropical spotted dolphins Stenella attenuata (mother male calf) near Tulum (Quintana Roo, Mexico), which died without a clear diagnosis cause death. This case confirms occurrence S. , increasing number local aquatic mammals to 20. As most other small cetaceans this region, conservation status species...
