Fig 3 in Two Asian freshwater snails newly introduced into South Africa and an analysis of alien species reported to date

Fig 3. (A) Tree based on 533 nucleotides of the cytochrome c oxidase subunit I mtDNA of lymnaeid samples, with the outgroup Planorbis corneus. (B) Tree based on 360 nucleotides of the mt 16S rDNA of lymnaeid samples, with the outgroup Stagnicola elodes. Numbers on branches represent Bayesian posterior probabilities percentages, neighbour-joining and maximum parsimony bootstrap values, respectively. Only values greater than 50 % are shown; * indicates support of <50 % for distance analysis. Figures adapted from Nadasan (2011). RRA – lymnaeid samples from Amatikulu, South Africa; LND – lymnaeid samples from Durban, South Africa.
