- Jaguar conservation in the American continent: the role of protected landscape and human-impacted biomes Erik-Joaquín Torres-Romero Gerardo Ceballos Francisco Botello José-Ignacio González Rojas Anthony-J. Giordano José-Vicente López-Bao Biología human biomes panthera onca protected areas Conservation planning indigenous People's Lands Introduction: Worldwide, expanding human activities continue to be a threat to many large-bodied species, including jaguars. As these activities continue, it is critical to understand how home range sizes will be impacted by human-modified landscapes. Objective: To evaluate the importance of protected and unprotected land on home-range size across their range. Methods: We used home range data from 117 jaguars in several habitat protection categories and human biome types. We used a Generalized Linear Mixed Model to test home range and spatial overlap with conservation categories and human biomes. Results: Most home-ranges were in Jaguar Conservation Units (62 %), followed by Protected Areas (21 %), Indigenous People's Lands (10 %) and Jaguar Movement Corridors (3 %), where 76 % of the jaguars lived inside one the first three conservation types. However, outside of conserved land, Rangeland, Cropland, Seminatural land and other human biomes were also important (24 % of the individuals). Jaguars in Rangeland, Cropland and Seminatural land had the largest home ranges. Conclusions: Although conservation land was dominant, human-impacted lands appear to play a considerable role in satisfying the spatial requirements of jaguars. 2023 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44975700041 https://www.redalyc.org/journal/449/44975700041/ https://www.redalyc.org/journal/449/44975700041/html/ https://www.redalyc.org/journal/449/44975700041/44975700041.epub https://www.redalyc.org/journal/449/44975700041/movil 10.15517/rev.biol.trop..v71i1.50507 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.1 Vol.71
