A review of the aquatic mammals of Belize.
Aquatic Mammals 42(4): 476-493. 2 figs. 1 tab. DOI 10.1578/AM.42.4.2016.476
–ABSTRACT: Characterizing species occurrence, abundance, and distribution is critical to the management of natural resources and the conservation of biodiversity. In the Western Caribbean, little information exists on the occurrence of aquatic mammals along the Mesoamerican Barrier Reef System and adjacent aquatic ecosystems. Herein, we present the first comprehensive review of aquatic mammals encountered in the marine and freshwater habitats of Belize. To determine which aquatic mammal species occur in Belizean waters, we conducted an extensive review of published and unpublished reports of aquatic mammals. We located 163 unique reports from museum and animal collections, journal articles, theses, news reports, conference proceedings, institutional reports, and verified accounts from personal observations. Our review confirms the presence of 17 aquatic mammal species in Belize: 15 cetaceans (Megaptera novaeangliae, Balaenoptera physalus, Ziphius cavirostris, Physeter macrocephalus, Kogia breviceps, Orcinus orca, Pseudorca crassidens, Globicephala macrorhynchus, Peponocephala electra, Stenella attenuata, S. clymene, S. frontalis, S. longirostris, Steno bredanensis, and Tursiops truncatus), one sirenian (Trichechus manatus manatus), and one carnivore (Lontra longicaudis annectens). Our findings provide the most up-to-date list of aquatic mammal presence in Belize. Given the limited data points obtained for most identified species, we recommend that systematic studies be conducted to investigate the status of the variety of aquatic mammals in the region to effectively monitor populations and devise strategies to mitigate the negative impacts of anthropogenic activity and climate change-related ecosystem shifts.

Is the Antillean manatee (Trichechus manatus manatus) back in town? Presence of the species at the "Area de Proteccion de Flora y Fauna Yum Balam", Quintana Roo, Mexico.
Revista Mexicana de Biodiversidad, https://doi.org/10.1016/J.RMB.2017.10.036.
–ABSTRACT: The Antillean manatee (Trichechus manatus manatus), considered endangered, is protected at national (Mexico) and international levels. Since Hurricane Gilbert in 1988, sightings of manatees have been rare at Conil Lagoon, located within the natural reserve "Area de Proteccion de Flora y Fauna Yum Balam". However, increased reports of sightings from local fishermen and tour guides suggest manatees may be repopulating the lagoon. Here we report 15 sightings of the Antillean manatee from 2011 to 2016. Group sizes ranged from 1 to 15 individuals, and we documented the presence of reproductive groups and mother-calf pairs. The apparent recovery of the species at Conil Lagoon and adjacent areas may be the result of local conservation efforts, or the result of changes in habitat use and distribution of the Caribbean population. A systematic, long-term local monitoring program is necessary to estimate manatee abundance and characterize their distribution in this area.

Accomplishments and challenges of the research on Antillean manatee: A bibliometric analysis
Latin American Journal of Aquatic Mammals, 18(1), 158-166. https://doi. org/10.5597/lajam00297
–ABSTRACT--The Antillean manatee (Trichechus manatus manatus) is an endangered subspecies of the West Indian manatee inhabiting countries of South America, Meso-America and the Caribbean. Basic and applied research is necessary to inform management plans for the effective recovery of this subspecies. The purpose of this study was to systematically review literature regarding Antillean manatees, without restriction of the research topic. Article selection and screening process are described. Our final database consisted of 456 publications, of which peer-reviewed
literature (articles, reviews, and notes in research journals)represent the most important type (63.4%), followed by BSc, MSc, and PhD theses (28.1%). Most of the research (70%) was conducted on wild manatees, 21,5% under human care conditions, and the rest a combination of both; the most common topics of study were 'ecology', 'conservation', 'morphology, anatomy and physiology', and 'behavior. The literature on Antillean manatee has expanded significantly over the last two decades across the region, with most of the research published in just the last five (25.4%) to 10 (44.6%) years. Most of the published work has been by Brazilian, Mexican, and Colombian researchers. However, an important amount of research remains as theses in Portuguese or Spanish limiting the dissemination of results. Relevant limitations for research and publication in Latin American countries may have an impact on the published literature on Antillean manatees, including scarce funding, poor facilities, language-related difficulties, and lack of a culture of publication. Avenues to melt scientific barriers may include increasing governmental investment on research, strengthening international networks, and improving the support to publish in high-impact journals.

Looking forward to Amazonian manatee conservation in Peru.
–AI-GENERATED ABSTRACT: This research focuses on the conservation efforts for the Amazonian manatee in Peru, particularly through the rehabilitation activities conducted at the Centro de Rescate Amazonico (CREA). Highlighting the successful release of rehabilitated manatees back into their natural habitat, the study underscores the collaboration with local communities and the involvement of academic researchers in monitoring the release outcomes. Ongoing research initiatives and future plans are mentioned, emphasizing the importance of continued conservation work for this vulnerable species.
