Samples used in the study to 1) find the optimal restriction enzyme combination, 2) evaluate the effect of sample type on loci recovery, 3) create alternative genotype matrices and reconstruct phylogenetic relationships, and 4) investigate the replicability of the protocol used in this study.

Samples used in the phylogenetic analyses are marked with an asterisk (*). All samples from UT Austin were collected in the field for the purpose of this study, while the rest of the samples were donated by colleagues or obtained from existing collections from either captive or field populations.
