Figure legends
Figure 1. Discriminant analysis of principal components of genetic variation among microsatellite samples of Lithobates catesbeianus invasive populations.
Figure 2. Parsimony consensus tree with haplotypes from native range (Austin et al., 2004), Europe (Ficetola et al., 2008), China (Bai et al., 2012), non-native areas of USA (Kamath et al., 2016), and samples from the present work. Clades East and West refer to distribution in the native range (Austin et al., 2004). Map contains the haplotypes’ distribution around the world. Color legend follows both map and phylogeny. Terminal labels with GenBank accession number starting with AY correspond to haplotypes found in the native distribution (Austin et al., 2004) and labels starting with KX correspond to haplotypes found in the invasive distribution in the USA (Kamath et al., 2016).
Figure 3. Bullfrog invasion pathways diagram based on literature information. Arrows and dates indicate the direction and date of each event of invasion, question marks indicate unknown source of introduction, and crosses indicates supposedly non-successful establishment of the introduced animals. The green arrow indicates possible successful genetic flow in disagreement with previous literature.
