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,
