Dear Marmam community, We are excited to share the news that the special issue on Aquatic Mammals of Central America has been published by the Revista de Biologia Tropical. The special issue includes 15 contributions represented by country as follows: Belize = 1, Guatemala = 4, El Salvador = 1, Nicaragua = 1, Costa Rica = 3, Panama = 4, and one regional paper that includes Central America, Mexico, and the United States. Of these 15 publications, 13 involved Central American researchers as primary authors or co-authors, and 12 were lead-authored by women. You can access the special issue in the following link: https://doi.org/10.15517/rev.biol.trop..v71iS4.2023 The list of articles and corresponding links are included below. Happy reading!
