Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Environmental DNA, Volume 7, Issue 4, July–August 2025.Using eDNA metabarcoding, we assessed fish diversity in isolated sinkholes in southern Brazil, uncovering signs of local extinction and species persistence. This approach offers a non‐invasive tool for biodiversity assessment and informs conservation efforts in unique karst environments.

Low‐Effort eDNA Sampling Reveals Fish Community Patterns in a Neotropical River Basin
Environmental DNA, Volume 7, Issue 4, July–August 2025.Low eDNA sampling effort (< 10 sample sites) using a portable on‐site kit with syringe filters and a modest water volume (< 500 mL per site) provided a rapid and robust snapshot of fish biodiversity. Environmental DNA based species richness increases along the upstream‐downstream gradient showing a significant negative correlation with river elevation ...
