Fig. 11 in Tectonic history and the biogeography of the freshwater fishes from the coastal drainages of eastern Brazil: an example of faunal evolution associated with a divergent continental margin

Fig. 11. (a) The main axes of Quaternary tectonics in Brazil (gray lines) (according to Saadi, 1993) and areas of coincident distributional rages of several species in both isolated coastal rivers and adjacent drainages. (b) The northeastern margin of Brazil, including the Parnaíba, São Francisco and adjacent coastal rivers (c) The Southern most Brazil, encompassing the Uruguay and surroundings coastal rivers as well as the headwaters of the Paranapanema, Ivaí, Iguacú and Ribeira de Iguape. (d) The area encompassed by the CRSB, in southeastern Brazil, including the coastal rivers and the adjacent upper Tietê and upper Iguaçu.

Fig. 9 in Tectonic history and the biogeography of the freshwater fishes from the coastal drainages of eastern Brazil: an example of faunal evolution associated with a divergent continental margin

Fig. 9. Cladograms of taxa and areas showing the sister-group relationships included in Pattern A. a) Catfishes of the family Trichomycteridae. b) Catfishes of the family Doradidae. The degree of inclusiveness of this pattern suggests the most ancient cladogenetic event that is still recognized in respect to the ichthyofauna of the Brazilian coastal rivers.
