Respostas metabólicas do matrinxã submetido a banhos anestésicos de eugenol - DOI: 10.4025/actascibiolsci.v29i3.474

Acta Scientiarum: Biological Sciences, 2007
O matrinxã (Brycon amazonicus) é uma espécie de interesse comercial. Porém, este peixe movimenta-se em excesso durante práticas de manejo, podendo sofrer ferimentos e perdas de escamas que, muitas vezes, resultam em taxas elevadas de mortalidade.

Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Unraveling Temporal Fish Diversity in a Neotropical Hydropower Reservoir: Comparing eDNA Metabarcoding to Traditional Fishing Methods

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.
