Gabrielle Rabelo Quadra,Fábio Roland,Nathan Barros,Olaf Malm,Adan Santos Lino,Guilherme M. Azevedo,J.R. Thomaz,Larissa Fonseca Andrade-Vieira,Milene Miranda Praça-Fontes,Rafael M. Almeida,Raquel Mendonça,Simone Jaqueline Cardoso,Yago Guida,José Marcello Salabert de Campos +13 more
TL;DR: This work found extremely high concentrations of particulate Fe, Al, and Mn in the impacted sites and observed cytogenotoxic effects such as alterations in mitotic and phase indexes, and enhanced frequency of chromosomal aberrations.

TL;DR: In this article , the authors use multiobjective optimization to identify portfolios of sites that simultaneously minimize impacts on river flow, river connectivity, sediment transport, fish diversity, and greenhouse gas emissions while achieving energy production goals.
Journal ArticleDOI
Extreme floods increase CO2 outgassing from a large Amazonian river
TL;DR: A positive feedback between climate change, extreme flooding, and CO2 outgassing from river water is indicated, and reconstruction of CO2 fluxes since 1968 indicates that extreme-flood years outgas 20% more CO2 per unit area than years without reported occurrence of extreme floods.
Journal ArticleDOI
Extreme drought boosts CO2 and CH4 emissions from reservoir drawdown areas
Sarian Kosten,Sanne van den Berg,Sanne van den Berg,Raquel Mendonça,Raquel Mendonça,José R. Paranaíba,Fábio Roland,Sebastian Sobek,Jamon Van Den Hoek,Nathan Barros +9 more
TL;DR: Although previous studies suggest that greenhouse gas emissions from reservoir sediment exposed to the atmosphere during drought may be substantial, this process has not been rigorously quantitatively quantified by as mentioned in this paper.
Journal ArticleDOI
Hydropeaking Operations of Two Run-of-River Mega-Dams Alter Downstream Hydrology of the Largest Amazon Tributary

TL;DR: Almeida et al. as mentioned in this paper examined whether the Madeira dams have affected downstream seasonal flood pulses and short-term (daily and sub-daily) flow dynamics, showing that the combined effects of these dams on seasonal flood pulse were modest.
