There is a need to revise the framework used project species risks under climate change (CC) and land-use/cover (LUCC) scenarios. We built CC risk index using latest Intergovernmental Panel on Climate Change framework, where function of vulnerability (sensitivity adaptive capacity), exposure, hazard. incorporated future LUCC scenarios as part exposure component. combined trait-based approach based biological characteristics with correlative ecological niche modeling, assigning scores species, taxonomic (orders), functional (trophic, body size, locomotion) groups terrestrial mammals occurring in Mexico. identified 15 projected lose their climatic suitability. Of 11 orders, Eulipotyphla, Didelphimorphia, Artiodactyla, Lagomorpha had highest scores. 19 trophic groups, piscivores, insectivores canopy, frugivores-granivores, herbivores browser, myrmecophagous five body-sized large-sized (>15 kg) seven locomotion arboreal semi-aquatics reduced suitable areas potential distributions by 37.5% (with CC), 51% LUCC) limited full-dispersal assumption. Reductions increased 50.2% 52.4% non-dispersal Species-rich (>75% species) 36% CC) 57% reductions suitability for 2070. Shifts projections species-rich number northeast southeast Mexico decreased northwest southern Mexico, suggesting important turnover. High-risk taxonomic, group diversities, highlight trends different impacts biodiversity ecosystem function.
