“…Similar results have been described for other vertebrate species occurring at high elevations (González-Fernández et al 2018;Sunny et al 2019;Vargas-Jaimes et al 2021). Climate is a main de ning factor for species distribution (Fourcade et al 2018;Bolom-Huet et al 2022;González-Fernández et al 2022) and there is evidence that climate alteration produces changes and reductions in habitable regions for snakes, in addition to modi cations in dispersal, growth, survival, and tness (Rugiero et al 2013;Combrink et al 2021). The three Conopsis species were primarily distributed in the valleys and mountains of the highlands of the TMBV.…”

Anthropogenic changes, such as land use and climate change, are the greatest threats to biodiversity, especially for reptiles, the second most endangered vertebrate class worldwide. Species distribution modelling was applied to assess how expected scenarios of future climate and land cover change might influence the geographic distribution and habitat connectivity of three Conopsisearthsnakes endemic to Mexico: Conopsis biserialis (Taylor and Smith, 1942),Conopsis lineata (Kennicott, 1859), and Conopsis nasus (Günther, 1858). In order to do this, two climate models were used, CNRM-CM5 (CN) and MPI-ESM-LR (MP), with the Representative Concentration Pathways of RCP 85 and the Maxent modelling method in ENMeval. The most important environmental variables affecting the distribution of the target species, as well as the environmental niche overlap between them, were also determined. C. biserialis, C. lineata, and C. nasus were found to be restricted by maximum and minimum temperatures as they are adapted to high elevations and temperate semi-cold climates; therefore, climate was a main determining factor for species distribution. As expected, all Conopsis species were predicted to face a reduction in their potential distribution with C. lineata possibly losing approximately 48.5% and C. biserialislosing 28.7%. However, the models were inconsistent in determining which species would suffer the biggest reduction in distribution in the future. Likewise, a reduction in connectivity was found for the three species of Conopsis, while the Sierra de las Cruces and Corredor Biológico Chichinautzin were determined as very important areas in terms of connectivity. Unfortunately, great losses of Abies and Pinus forests occurred in these areas between 2011 and 2014, along with an increase in the agricultural activity that compromises the populations of these species when intensively managed. Most of the potential distribution of these species are found in close proximity to agriculture and outside of protected areas, which is why it is extremely important to create protected areas for reptile species that live in these parts of central Mexico.
