FIGURE 1. Geographic distribution of Rhinella marina populations sampled for two mitochondrial markers and morphometric landmarks across the Andean cordillera in northern Venezuela. The circles indicate locations of specimens sequenced in this study and the squares indicate locations associated to previously published sequences used in this study. Black circles and squares correspond to eastern populations and white circles and squares to western populations. The geographic coordinates of localities are given in Table 1. The genetic distances between western and eastern populations (grey) are greater than between western populations (black) or between eastern populations (white) (see text for details).
