Sampling localities and body sizes (snout-vent length, SVL) of Rhinella atacamensis. A Geographic location of the 11 localities included in this study (numbers given in Table 2). Colors represent different levels of precipitation (mean annual precipitation) and the dashed line delimits the approximate distribution of the species. B Geographic variation of body size (mean and standard deviation of SVL of each locality) as a function of latitude (R² = 0.91). The photographs show the differences in size of males and females of three representative localities (numbered according to Table 2). Black bars indicate 10 cm. The map is own elaboration
