- Projected impact of global warming on the distribution of two pocket mouse species with implications on the conservation of Heteromys nelsoni (Rodentia: Heteromyidae) Consuelo Lorenzo Tamara Rioja-Paradela Arturo Carrillo-Reyes Eugenia Sántiz-López Jorge Bolaños-Citalán Biología rodents climate change Area of occupancy distribution range extent of occurrence Introduction: Understanding how species respond to climate change is critical for implementing conservation strategies. Objective: We explain through potential distributions and changes in altitudinal variation, the possible impacts of climate change in an endangered micro-endemic rodent of Mexico with narrow altitudinal range, Heteromys nelsoni and a rodent with a wide distributional and altitudinal range, Heteromys goldmani. Methods: We obtained historical and current records of both Heteromys species. Potential distribution models were generated using Maxent, including altitudes for each species and bioclimatic layers. We determined the Extent of Occurrence and Area of Occupancy for H. nelsoni according to the criteria of the IUCN in order to generate information about its risk status. Results: The altitude is not a variable that determines a shift in the distribution caused by climate change. In contrast, the temperature and precipitation are important for the potential distribution of both Heteromys species. The future changes in climatic conditions could reduce the area of suitable habitat for both species. Conclusions: The distribution surface is not greater than 33.44 km2 for H. nelsoni. Therefore, is urgent to re-evaluate their conservation status by the IUCN, mainly in its B criterion, and to take specific actions for their conservation. We suggest the creation of a terrestrial protected area. 2019 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44965908009 https://www.redalyc.org/journal/449/44965908009/ https://www.redalyc.org/journal/449/44965908009/html/ https://www.redalyc.org/journal/449/44965908009/44965908009.epub https://www.redalyc.org/journal/449/44965908009/movil DOI 10.15517/RBT.V67I6.36321 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.6 Vol.67
