Historical relationships of areas of endemism of the Brazilian Atlantic rain forest: a cladistic biogeographic analysis of harvestman taxa (Arachnida: Opiliones)

摘要: Based on a cladistic biogeographic analysis of 6 species-level phylogenies harvestman taxa, we searched for congruence in the historical relationships 12 areas endemism Brazilian Atlantic Rain Forest. We constructed general area cladograms using Primary Brooks Parsimony Analysis (BPA), BPA nodes, and paralogy-free subtree analysis. These analyses resulted cladograms, that allow to infer pattern among from Northern related basally showing main disjunctions at Doce River Valley Todos os Santos Bay/Sao Francisco Valley. The remaining were included southern southeastern block, separated by Ribeira do Iguape Incongruence Length Differences tests showed no significant incongruence resulting other matrix partitions. concluded tectonism ancient marine transgressions probable processes responsible disjunctions, whereas Neogene refugia seem have caused more recent disjunctions. redundancy suggest model reiterative barriers diversification multiple times evolution renewal biogeography search common patterns are discussed.
