Habitat suitability maps of P. hispanicus lineages. Habitat suitability maps derived from ecological niche models for P. hispanicus edwardsianus (a), P. hispanicus hispanicus Central lineage (b) and P. hispanicus hispanicus Western lineage (c) using seven temperature, four precipitation, one vegetation and one topographic predictor. Sampled populations are indicated by circles (P. hispanicus edwardsianus populations in blue, P. hispanicus hispanicus Central lineage populations in red, Western lineage populations in green), and habitat suitability scores are listed in a graded colour series on the left border of the map. Potential contact zones (see Additional File 3 - Figure S3) are enlarged in separate panels. Overlapping habitat suitability predictions for P. hispanicus edwardsianus and P. hispanicus hispanicus Central lineage (d), P. hispanicus hispanicus Western lineage and P. hispanicus edwardsianus (e), and P. hispanicus hispanicus Central lineage and P. hispanicus hispanicus Western lineage (f) are given in separate panels. In these maps areas are coloured in brown if the habitat suitability scores of a lineage pair were larger than zero for both lineages.
