Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

Fisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

Fire‐driven forest degradation enhances termite activity and accelerates litter decomposition in the Amazonia rainforest

Insect Conservation and Diversity, EarlyView.
Forest degradation increased termite‐mediated litter decomposition, whereas no such effect was detected in undisturbed forests. Reduced ant predation and altered forest conditions were associated with higher termite abundance and faster litter decomposition.
