Anthropogenic Factors Drive the Depletion of Fish Functional Β Diversity Within and Outside Two National Reserves in the Peruvian Amazon

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT Understanding the impact of human activities on fish communities is critical for the effective conservation of Amazonian ecosystems. In this study, we sampled environmental DNA (eDNA) from 17 sites (lakes and rivers) in two Peruvian national reserves, Pacaya‐Samiria and Allpahuayo‐Mishana, using a metabarcoding approach with four genetic ...
