“…Moreover, many species of shrew (genus Cryptotis ) are restricted to highly endangered habitats, such as montane cloud forest (Guevara & Sánchez‐Cordero, 2018a , 2018b ). Thus, the current conservation status of several endemic species of shrews (Mayani‐Parás et al, 2022 ) can accelerate future conservation threats under CC and LUCC scenarios, as shown in this study.…”

“…However, even under a non‐dispersal assumption, suitable climatic condition reductions only reached an additional 10% (Table 3 ; Appendix S8 ). We found higher reductions in species potential distributions projected under LUCC/WP than by CC; LUCC/WP assumes that rainfed agricultural and cattle grasslands are unsuitable habitats for terrestrial mammals to establish resident and reproductive populations (Linero et al, 2020 ; Mayani‐Parás et al, 2022 ; Peterson et al, 2011 ). This result contrasts with the study of Zamora Gutierrez et al ( 2018 ) in which CC appeared to have a stronger negative effect than LUCC.…”

“…However, there is not enough biological information for most small mammals to assure that rainfed agriculture area will allow permanent and reproductive populations to become established (Hidalgo‐Mihart et al, 2019 ); for example, these populations may be exposed to adverse conditions, such as those created by the use of pesticides (Torquetti et al, 2021 ). LUCC that results in extensive area loss of suitable habitat for species currently represents the main cause of conservation threats for terrestrial mammals in Mexico (Chacón‐Prieto et al, 2021 ; Cuervo‐Robayo & Monroy‐Vilchis, 2012 ; Mayani‐Parás et al, 2021 , 2022 ) and in other Neotropical biodiversity hotspots (Galetti et al, 2021 ; Linero et al, 2020 ).…”

“…Most species conform to large population abundances although illegal hunting and habitat loss are having a negative impact on several species of lagomorphs, such as L. callotis , L. flavigularis , and R. diazi (Mayani‐Parás et al, 2021 ; Velázquez, 2012 ), putting some species under a current high risk of extinction, such as the microendemic Omilteme cottontail rabbit S. insonus (Velázquez, 2012 ). Other orders of mammals are experiencing habitat loss and illegal hunting, which pose increasing challenges that should be incorporated in future conservation strategies (Chacón‐Prieto et al, 2021 ; Mayani‐Parás et al, 2021 , 2022 ; Sánchez‐Cordero et al, 2014 ).…”

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