Structure results from RADseq data for L. rubellus collected from former mine sites and nearby control sites across the UK. Each bar represents an individual, with the proportion of colours reflecting affiliation with differentiated populations. a represents all individuals sampled (n = 128), where K = 2, and highlights the distinctions between lineages A and B, coloured red and blue, respectively. b and c demonstrate the best supported clustering of individuals belonging to lineage A (n = 66, K = 3) and B (n = 62, K = 2), respectively
