Taxonomic and phylogenetic beta diversity in headwater stream fish communities of the Paraná and Paraguai River basins Neotropical Ichthyology
Nakamura,Gabriel; Vicentin,Wagner; Súarez,Yzel Rondon.
ABSTRACT Patterns of species replacement and richness differences along environmental gradients or ecoregions shed light on different ecological and evolutionary mechanisms acting on community structure. Communities of aquatic ecosystems of different watersheds are supposed to host distinct species and lineages. Quantifying and understanding the degree to which these differences are affected by environmental and biogeographical factors remains an open question for these environments, particularly in the Neotropical region. We investigated patterns of taxonomic and phylogenetic composition of headwater streams of the Paraná and Paraguai River basins to understand how local and biogeographical factors affect the assembly of fish communities. We also...
