Figure 3

Genetic distances between localities of C. tenuispina, including all individuals. (a) Heatmap based on FST distances between localities and; (b) unrooted neighbor-joining tree based on FST distances between localities; values on the branches represent genetic distances. Codes in purple represent sites from the Canary Islands, in red from the Cantabrian Sea, turquoise from the Alboran Sea, blue from the W Mediterranean, and orange from the E Mediterranean. On the heatmap, white background comparisons are non-significant (p ≤ 0.01). Values of FST distances and their associated p-values are included as Supplementary material S7. This figure was created with the gplots v 3.0.3 (a) and adegenet v 2.1.3 (b) packages in R.
