Fig. 2From: Genetic variation in populations of the earthworm, Lumbricus rubellus, across contaminated mine sitesPrinciple component analyses of RADseq data for populations of L. rubellus collected across the UK, representing all individuals (a, n = 128), those from lineage A (b, n = 66) and Lineage B (c, n = 62). Triangles represent individuals originating from former mine sites, while circles represent those from nearby control sites. The amount of variance explained by each component is noted on their respective axesBack to article page
