Collection sites and general genetic structure in Arbacia lixula. a Sampling sites and pie charts of the percentage of each cluster (K = 3) per site obtained from STRUCTURE as represented below, and b STRUCTURE barplot with the posterior probabilities of individual assignment of the most probable number of clusters for the whole data set (K = 3). Clusters are represented by different colours (yellow, red and blue), and each bar represents a different individual. Numbers and red lines represent the four different marine barriers considered: Mid-Atlantic barrier (1), Gibraltar Strait (2), Almeria-Oran front (3) and Siculo-Tunisian Strait (4)
