Antillean manatee calves in captive rehabilitation change vocal behavior in anticipation of feeding

Zoo Biology, 2023
Antillean manatee calves in captive rehabilitation produced more calls before feeding than during and postfeeds. Our findings indicate they anticipate feeding events and change their vocal behavior as a result. Abstract Captive animals typically develop anticipatory behaviors, actions of increased frequency done in anticipation of an event such as ...

Vocal complexity in Antillean manatees (Trichechus manatus manatus)

Behaviour, 2022
Abstract Vocal complexity can be expressed through variations in repertoire size, structure, and individual manatee repertoires. Here we aimed to assess the complexity of the vocal behaviour of Antillean manatees living in captivity (i.e., artificial pools) and in reintroduction enclosures (i.e., natural enclosures placed in an estuarine area ...

Reproductive success of Antillean manatees released in Brazil: implications for conservation

Journal of the Marine Biological Association of the United Kingdom, 2022
AbstractActions to rescue, rehabilitate and release calves of manatees are the main initiatives and strategies for conservation of the species in Brazil. The survival rate of animals in a natural environment and the reproductive success, identified by birth records, are some of the indicators used to estimate the release success for manatees.

Baseline urinalysis results in 32 healthy Antillean manatees (Trichechus manatus manatus)

Journal of the American Veterinary Medical Association, 2021
Abstract OBJECTIVE To describe results of analysis of free-catch urine samples collected from Antillean manatees (Trichechus manatus manatus) under human care in the Caribbean. ANIMALS 32 Antillean manatees in 5 Caribbean oceanaria and rescue centers. PROCEDURES Urine samples were obtained by opportunistic free catch during physical examination or

Activities and social interactions in captive Antillean manatees in Mexico

mamm, 2010
Abstract Behavioural research in endangered manatees is essential for successful conservation management. We examined the activities and social interactions of a captive group of Antillean manatees located in the Dolphin Discovery Park in Mexico. The group studied was composed of two adults, one subadult and one calf.

Behavioural and physiological responses of captive Antillean manatees to small aerial drones

Wildlife Research, 2021
Abstract Context Unmanned aerial vehicles or drones are powerful tools for wildlife research. Identifying the impacts of these systems on target species during operations is essential to reduce risks of disturbance to wildlife, to minimise bias in behavioural data, and to establish better ...

Thoracolumbar kyphoscoliosis in a captive geriatric Antillean manatee (Trichechus manatus manatus)

Journal of Comparative Pathology
Vertebral column deviations, namely scoliosis, kyphosis, lordosis and combinations thereof, are poorly characterized in marine mammals. Here we present the clinical history and the post-mortem pathological and computed tomography (CT) scan analysis results on a 52-year-old captive female Antillean manatee (Trichechus manatus manatus) from Brazil.

Plastic pollution on beaches in an Antillean manatee conservation area, Brazil

Marine Pollution Bulletin
The presence of plastic debris along shorelines is a widespread problem, and plastic debris can interact directly with marine wildlife. In northeast Brazil, the Antillean manatees are the most common marine mammals and use estuarine waters mainly as their home range. We aimed to investigate the characteristics of plastic debris on the estuarine-oceanic

Using craniometrical predictors to infer body size of Antillean manatees

mammalia, 2014
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 and data­ bases of Antillean manatees in Mexico to infer body mea­ surements and to determine the body mass (BM)/body length (BL) relationship ...
