Hybrid zones of Natrix helvetica and N. natrix: Phenotype data from iNaturalist and genetics reveal concordant clines and the value of species-diagnostic morphological traits


	Nuclear genomic identity of genetically studied samples (membership to microsatellite clusters; n = 952). A Entire study range, B Rhine transect, C Alpine transect, D Italian transect. Data are from Kindler et al. (2017) and Asztalos et al. (2021a).
