Figure 1 : A) Distribution map of Haploniscus bicuspissampled around Iceland from BIOICE, IceAGE and literature data. Black
symbols refer to the type locality by Sars (1877) and Wolff (1962).
B)-D) Unrooted genetic networks. B) COI haplotype network calculated
with SplitsTree, C) network based on nuclear ddRAD loci calculated with
SplitsTree and D) COI haplotype network calculated with Network. In B)
and C), colors indicate lineages delimited by COI (highlighting the
conflicts in the nuclear dataset). In D), colors represent single
stations (see Figure A). Individuals are not shown to improve the
readability of the figure, please refer to Supplemental Figure S1 for
that.
