Illuminating the Dark: Using eDNA Metabarcoding to Study the Unique Ichthyofauna of the Furnas Formation Sinkholes

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 ...

Length‒Weight and Length‒Length Relationships of Freshwater Fish Species Caught by Professional Fishermen in the Itaipu Reservoir, Brazil

Journal of Applied Ichthyology, Volume 2025, Issue 1, 2025.
Length‒weight relationships (LWRs) and length‒length relationships (LLRs) were estimated for 63 and 58 freshwater fish species, respectively, captured in the Itaipu Reservoir, Paraná River Basin, Paraná State, Brazil. Sampling was carried out from March 1987 to July 2024 at 63 professional fishing sites within the reservoir’s area of influence ...
