Species georeferenced records
Our study focused on 21 taxa native to the BCP (Table 1), including eight mammals, four plants and nine reptiles. We selected species for which their genetic structure on the peninsula was previously published. We aimed to represent species that inhabit different elevations (highland or lowland), which we hypothesized could respond differently to LGM conditions. We identified the number of genetic clades described in previous studies for each taxon and classified them according to their geographic location in southern (south of the Vizcaíno peninsula, ~27ºS), northern (north of ~27ºS including the Vizcaíno peninsula) and clades without north-south genetic differentiation (unstructured). For each taxon we obtained georeferenced records from the Global Biodiversity Information Facility (https://www.GBIF.org). Occurrences were manually filtered to accurately represent each taxon distribution, and a minimum convex polygon of each clade’s distribution was used to assign occurrences within a 10 km buffer to their corresponding genetic clade. The values for the 19 bioclimatic variables (Table S1) were obtained from each occurrence point.
Table 1. List of species selected for this study indicating their corresponding taxonomic group (M: mammal; P: plant; R: reptile) and elevation (H: highland; L: lowland). We also indicate the reference (Ref) describing the species’ genetic structure, along with the number and location (N: north; S: south; -: unstructured) of described genetic clades, and the type of genetic data (mit: mitochondrial; plastid; nuclear; or RADseq) used to determine the genetic structure. Finally, we show the number of occurrence records, the AUC value and the selected variables to build the ecological niche model for each genetic clade.
