Cytotaxonomy and phylogeography of Psalidodon rivularis species complex
The objective of this study is to determine whether Psalidodon rivularis represents a single polymorphic species or a group of cryptic and/or semicryptic species in the Sao Francisco River basin. For this work, we submitted DNA extracted from 13 specimens of the Psalidodon rivularis complex and 1 specimen of Psalidodon aff. paranae for next-generation genomic sequencing (NGS).
