Distribution of genetic diversity (mitochondrial <i>cytochrome oxidase II</i> (<i>COII</i>) sequences) of <i>Xylocopa darwini</i> across the Galápagos Islands.

<p>(A) Distribution of mitochondrial haplotypes within populations (see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0120597#pone.0120597.s003" target="_blank">S1 Table</a>). (B) Distribution of haplotypes across islands. (C) Statistical parsimony network of haplotypes; lines represent single nucleotide substitutions, and dots indicate missing haplotypes (extinct or not found). Circle sizes are proportional to the number of sequences obtained for each haplotype.
