Figure 5 in A phylogeographical perspective on the ex situ conservation of Aylacostoma (Thiaridae, Gastropoda) from the High Paraná River (Argentina-Paraguay)

Figure 5. Divergence times for Aylacostoma from the High Paraná River. The nodes in the phylogram are presented according to the mean value of oldest estimated age, assuming different divergence rates and substitution models. Divergence between A. chloroticum and A. brunneum = 3.60 Mya (K2P); divergence within A. chloroticum = 0.38 Mya (GTR+I+G). The bars around each node represent the minimum and maximum estimated age. Time scale adapted from the International Chronostratigraphic Chart (International Commission on Stratigraphy, 2014).
