Figure 1 in Voluntary thermal maximum of grassland vipers (Vipera spp.): environmental drivers and local adaptation

Figure 1. Distribution records of grassland vipers used in the study (white dots) and approximate distribution of their range (polygons) according to the taxonomy in Freitas et al. (2020). Numbered points and taxon names in yellow letters indicate populations measured for VT max and white dots indicate locations used to extract environmental data and estimate pVT max. Photos by E.
