Map of Puerto Rico, where municipalities with samples of Epicrates inornatus are individually colored.

A haplotype network is shown above the map, with each haplotype color-coded by the proportion of individuals from each municipality represented in the haplotype. Haplotype circles are sized proportionally to the number of individuals represented in each haplotype, where the smallest circles represent one individual and the largest represents 13 individuals. Line segment lengths are arbitrary, and the smallest black circles represent un-sampled mutational steps. Three haplogroups are recovered and separated into gray boxes. Two cave (Agrodel [Hatillo], and Mata de Plátano [Arecibo]) and two surface (Río Encantado [Ciales], and Dorado Beach [Dorado]) populations are labeled both on the map and on the haplotype network.
