Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

open access: yesJournal of Fish Biology, Volume 108, Issue 3, Page 949-962, March 2026.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Anthropogenic Barriers Limit Fish Access to Essential Habitats in the Amazon in the Face of Climate Change

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
Rivers across the Amazon Basin are increasingly threatened by climate change and dam construction, which restrict fish movements. We combined climate projections with river‐network connectivity analyses to identify where suitable habitats for frugivorous and socioeconomically important fish are likely to persist and where access may be lost due to ...
