Honduras discovered that it has 227 native mammal species and the number could continue to grow

The research published in ZooKeys updated for the first time since 1998 the overview of the mammals of Honduras (Illustrative Image Infobae). The most comprehensive review of Honduran mammals in nearly three decades confirmed 227 native mammal species in the country, in addition to 3 introduced rodent specimens, and suggested that the total could grow to 258 if other 28 species are verified in the future. The study published in ZooKeys was the result of 8 years of international research and updates the general picture of this fauna in the country for the first time since 1998. The research was led by Manfredo A. Turcios-Casco, affiliated with the Association for Sustainability and Scientific Research in Honduras (ASICH) and the State University of Santa Cruz in Brazil, along with 14 co-authors from institutions in Honduras, the United States, Brazil, Guatemala, and Costa Rica. Participating entities include Panthera Honduras, the Smithsonian Institution, and the Wildlife Conservation Society. The study compiled nearly 200 pages with species profiles, distribution data, and conservation summaries. According to the Phys.org report, the review verified native types distributed across 146 genera and 42 families, in addition to introduced rodents. A study on the mammals of Honduras confirmed 227 native species and added 3 introduced rodents (Illustrative Image Infobae). The project began when Turcios-Casco was pursuing a master's degree and studying the conservation status of xenarthrans in the area. "At that time, I realized something surprising: despite Honduras being one of the countries with the greatest biodiversity in Central America, its mammal fauna had not been thoroughly reviewed since 1998," the student noted. This finding led to an investigation that started with a team of 4 people and eventually became a broader international collaboration. Phys.org detailed that museum curators, taxonomists, field biologists, and conservation specialists from several countries participated in the development of the work. The review of Honduran mammals indicated that the total number of species could reach 258 if other 28 are verified (Illustrative Image Infobae). To build the survey, the group evaluated more than 300,000 records from museum collections, scientific publications, technical reports, and field observations that had not been published and date back to the 1960s. Turcios-Casco himself pointed out that verification was the main difficulty of the study, as each record had to be critically examined. Added to this was the effect of changes in the scientific classification of animals, which forced the team to keep updating the profiles even a few days before the final manuscript submission. The research on Honduran mammals also included common names used by indigenous peoples and local communities (Illustrative Image Infobae). Modern distribution maps were not available for certain groups, including squirrels, raccoons, and various small rodents. Additionally, for species widely present in the area, such as opossums and skunks, documentation remains scarce in the territory. The review incorporated conservation summaries aimed at guiding research priorities and public policy decisions. According to Turcios-Casco, conservation starts with knowledge, and one of the biggest difficulties in protecting biodiversity is that often animals that are not sufficiently known are attempted to be safeguarded. The review of Honduran mammals showed that modern distribution maps are still missing for squirrels, raccoons, and small rodents (Illustrative Image Infobae). The study also incorporated cultural knowledge by including common names used by indigenous peoples and local communities along with the scientific record. This decision was part of an effort to narrate the story of the region's mammals in a broader way and not just as a list of verified species. The authors also expressed hope that the research will serve as a foundation for a new generation of Honduran biologists. In this sense, the work is presented both as a synthesis of what is already known and as a sign of how much remains to be studied about the country's natural heritage.
