Figure 5From: Contemporary habitat discontinuity and historic glacial ice drive genetic divergence in Chilean kelpThe effect of beach length on phylogeographic structure in bull-kelp in central Chile. Maximum length of beaches between pairs of adjacent sampled localities in central Chile [data estimated from Google Earth satellite images]. Upper: locality pairs between which there is a marked mitochondrial (COI) genetic disjunction (Nei's raw average pairwise difference, D, > 1.0) are shown in black, whereas genetically-similar locality pairs (D < 1.0) are shown in grey. Lower: Nei's raw average pairwise differences (D) for COI, plotted against maximum uninterrupted beach length, between all adjacent locality pairs in central Chile.Back to article page
