Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

open access: yesFreshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon

open access: yesJournal of Fish Biology, Volume 108, Issue 3, Page 881-893, March 2026.
Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

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 ...
