Figure 1.

Phylogenetic relationships among 46 unique mitochondrial haplotypes from 95 individual apple snails for which complete sequences were generated. Analyses were based on combined 12S-16S (~1,900 bp) and COI (~658 bp) datasets including native-range and introduced apple snail samples. Locality information is provided in subsequent figures and Additional file 1. Bayesian posterior probabilities (P.P.) are listed above branches, maximum parsimony (M.P.) bootstrap percentages (B.P.) below. The support values for clades containing non-native apple snails as well as a clade of Pomacea paludosa are shown in boldface.
