Figure 3From: Genetic variation in the invasive avian parasite, Philornis downsi (Diptera, Muscidae) on the Galápagos archipelagoEstimated number of populations from STRUCTURE (a) and GENELAND (b) analyses. (a) Mean ( ± SD) probabilities of the data (LnPr [X|k]) over three replicate STRUCTURE runs plotted as a function of the putative number of clusters (k); (b) Posterior density distribution of the number of clusters estimated from GENELAND analysis in three replicates.Back to article page
