Predicted impacts of proposed hydroelectric facilities on fish migration routes upstream from the Pantanal wetland (Brazil)

open access: yesRiver Research and Applications, Volume 36, Issue 3, Page 452-464, March 2020., 2020
Abstract There are 104 hydroelectric facilities proposed to be installed in the watersheds that feed the Pantanal, a vast floodplain wetland located mostly in Brazil. The Pantanal is host to 23 long‐distance migratory fish species that ascend upland tributaries to spawn.

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

open access: yesAustral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.
