Geographic distribution, haplotype network, discriminant analysis of principal components, and population structure of the American crocodile.
A) C. acutus distribution range based on most recent data of presence, and sampling localities color-coded by country (Base map credit: NASA Earth Observatory); B) Neighbor-joining haplotype network of the mtDNA control region, circle size is proportional to haplotype frequency, and hatch marks indicate mutation steps; C) scatterplot of DAPC with PC1 and PC2; D) estimated Bayesian genetic structures based on 11 microsatellite loci, with K = 3 and K = 4. Samples are colored according to geographic location.
