Statistical parsimony network for mtDNA (CR and <i>cytb</i>) sequences of <i>I. monticola</i>.

<p>Circle size reflects the frequency of each haplotype. Small black circles indicate haplotype states that are necessary intermediates but are not present in the sample. Each line represents a single mutational step connecting two haplotypes. CAMOR (Cantabrian Mountain Range) and OCCIDENTAL refer to population assignments based on geographical localization.
