Was the Dry Diagonal of South America a Barrier for Dispersing Pteridaceae (Polypodiopsida) Species Between the Brazilian Atlantic Forest and Amazon Forest?
Aim
We sought to assess how phylogenetic patterns within the fern family Pteridaceae are related to the history of the Amazon Forest and the Brazilian Atlantic Forest, as well as the Dry Diagonal of South America. The age of taxa present in these regions was estimated, as well as those found in previously identified areas of endemism for the family. We verified whether the Dry Diagonal constitutes a barrier to the dispersal of taxa between the Brazilian Atlantic Forest and the Amazon Forest, and investigated whether the latter domain is a source area of species.
Location
Neotropics, including the Amazon Forest, Brazilian Atlantic Forest and Dry Diagonal.
Taxon
Pteridaceae (Polypodiopsida).
Methods
We compiled rbcL and atpA sequences for all Pteridaceae species available in GenBank and obtained a dated phylogeny using fossil information and secondary calibrations. Using the resulting chronogram, we performed ancestral area reconstructions using BioGeoBEARS.
Results
Species from the Amazon Forest, Brazilian Atlantic Forest and Dry Diagonal tend to originate during the Eocene/Oligocene transition, in the Miocene or the Pleistocene. Vicariance events explain the origin of many of these species; however, dispersal events also played a significant role in the biogeographic history of the group. The areas of endemism of Pteridaceae in Brazil have distinct biogeographic histories. The areas of southeastern Brazil and southeastern Bahia likely originated more recently, driven by Pleistocene climatic changes and habitat specialisations. In contrast, southern Brazil and the Guiana Shield have older taxa, which originated in regions with climatic and (or) geological stability through habitat specialisations.
Main Conclusions
The origin of most species present in the Amazon Forest, Brazilian Atlantic Forest and Dry Diagonal most likely resulted from climatic changes during the Miocene and Pleistocene. The Dry Diagonal does not constitute a barrier to the dispersal of Pteridaceae species, as taxa shared between the Brazilian Atlantic Forest and Amazon Forest are common. The Amazon Forest is not the primary source area of species within the global context of the family.
期刊介绍：
Papers dealing with all aspects of spatial, ecological and historical biogeography are considered for publication in Journal of Biogeography. The mission of the journal is to contribute to the growth and societal relevance of the discipline of biogeography through its role in the dissemination of biogeographical research.
