The Madrean Archipelago harbors one of the most diverse mammalian communities in North America. We used the Web of Science literature search tool to assess the diversity of peer-reviewed publications on mammals in Arizona and New Mexico as an indicator of publications in the region. The number of publications of all mammals was lower than expected with a mode of 0 and a median of 1. Species were not studied equally in Arizona with most measures suggesting a disproportionately large number of publications on the Order Artiodactyla and small numbers of publications on the Orders Rodentia and Chiroptera. Large mammals and those found in many Arizona counties tend to be the subject of more publications. Despite the great diversity of the region, a dearth of published data on mammalian species is evidenced within the Madrean Archipelago, especially among the Rodentia and Chiroptera.

Climate change is a serious immediate and long-term threat to wildlife species. State and federal agencies are working with universities and non-government organizations to predict, plan for, and mitigate such uncertainties in the future. Endemic species may be particularly at-risk as climate-induced changes impact their limited geographic ranges. The Madrean Archipelago is characterized by high levels of endemism, natural fragmentation, and increasingly poor connectivity among the mesic montane islands within an arid matrix of low elevation deserts and grasslands. The region already has experienced an increase in temperature and this trend is predicted to accelerate over the remainder of the century. We assessed patterns of elevational distribution of reptiles and mammals within the Madrean Archipelago. We examined incremental temperature increases and determined how much reptilian and mammalian biodiversity is at-risk to be lost from montane islands due to elevational and geographic restriction. We estimate that 15 to 20% of all reptile and mammal diversity is at risk of loss by 2100 based solely on predicted patterns of upslope migration of biotic communities driven primarily by climate change. With this significant proportion of native species, we suggest that this emphasizes the need to continue traditional management actions focused on habitat improvement, restoration and connectivity for the majority of species in combination with innovative and active management strategies directed at the subset that is most at risk of extirpation.
