Aquatic and Terrestrial Invertebrates Support Fish Assemblages of Amazonian Streams
Freshwater Biology, Volume 71, Issue 5, May 2026.ABSTRACT The Amazonian stream network is remarkable not only for its extent but also for its rich fish diversity. These streams are interconnected with the surrounding forests. However, key ecological aspects of Amazonian freshwater ecosystems, such as energy flows and carbon sources sustaining fish assemblages, remain poorly understood. In this study,

Environmental DNA, Volume 8, Issue 2, March/April 2026.Comparing eDNA metabarcoding and gillnet surveys in a Neotropical reservoir, this study finds that eDNA detects greater species richness yet reveals distinct assemblage structures. The results underscore the value of integrating both methods to achieve comprehensive biodiversity monitoring in hydropower‐impacted ecosystems.
