Dear Colleagues, On behalf of the Guest Editors, I am pleased to announce that the Latin American Journal of Aquatic Mammals (LAJAM/) will publish a *Special Issue on the Biology and Conservation of Manatees* by the end of 2023. LAJAM is published twice a year by Sociedad Latinoamericana de Especialistas en Mamíferos Acuáticos/Sociedade Latino-Americana de Especialistas en Mamíferos Aquáticos (SOLAMAC). The journal publishes articles concerning research, management, and conservation biology of aquatic mammals in Latin America. Articles on theory or techniques broadly applicable to the study of aquatic mammals are also considered. For this Special Issue, we encourage submissions dealing with the distribution, population status, biology and ecology of manatees, as well as dealing with human conflicts, population genetics, ex-situ conservation, and sampling methods. For this issue, LAJAM will publish three types of contributed manuscripts: Articles, Notes and Protocols. Manuscripts must be written in English. All submitted manuscripts will be reviewed by at least 3 anonymous referees for scientific content. Guest Editors of the special issue are Drs. Carol Meirelles, João Carlos G. Borges, Rodrigo S. Amaral, and Nataly Castelblanco-Martínez. We invite you to submit your article prior to or by the 31st of July, 2023. The final decision will be communicated by 30 November 2023. The Guidelines for Authors are available here https://lajamjournal.org/index.php/lajam/about/submissions. Manuscripts can be submitted online here https://lajamjournal.org/index.php/lajam/login?source=%2Findex.php%2Flajam%2..., and to do so, at least one author will need to register as a user. Please, declare in your cover letter that you wish to submit your manuscript to the *Special Issue on the Biology and Conservation of Manatees*. Please direct any enquiries to Dr Carol Meirelles: c.meirelles@oceans.ubc.ca<mailto:c.meirelles@oceans.ubc.ca> Sincerely, Carol.
