Haplotype network for the mtDNA <i>cox1</i> dataset for <i>Cryptopygus antarcticus travei</i> from Marion Island.

<p>Each large circle represents a unique haplotype and each line represents one mutational step. Numbers in parentheses indicate haplotype frequency (when >1), while ‘’ indicates an inferred or missing haplotype. Shading indicates whether individuals with that haplotype have low (<0.010 µlO₂.µg⁻¹.hr⁻¹; white), medium (0.0010≤<i>x</i>≤0.0020 µlO₂.µg⁻¹.hr⁻¹; light grey) or high (>0.0020 µlO₂.µg⁻¹.hr⁻¹; dark grey) metabolic rates. This figure is not to scale.
