River conservation and restoration in croplands: can we improve the common agriculture policy as an instrument of practice?

Restoration Ecology, Volume 34, Issue S1, May 2026.
Abstract This study investigates the integration of river restoration with the Common Agricultural Policy (CAP), focusing on the differences between European Union (EU) and Portuguese documents regarding river restoration terms. A thematic content analysis highlights that despite the varying document sizes, the proportion of mentions related to river ...

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

Austral 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

Environmental 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.
