A Proportion of loci shared among individuals in the Am4s2 dataset. Loci shared between individuals (black circles) or successfully amplified within an individual (red circles) expressed as the proportion from 0 to 1 of all 48,062 loci scored in the Am4s2 dataset. Plotted with the phylogenetic tree based on maximum likelihood inference, with branch lengths scaled in substitutions per nucleotide. B Ordination of Alpheus samples based on nonmetric multidimensional scaling of the locus presence-absence matrix, K = 3, colored by species
