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

Journal of Fish Biology, EarlyView.
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 ...

Relationships between Potentially Toxic Elements in intertidal sediments and their bioaccumulation by benthic invertebrates.

PLoS ONE, 2019
The bioaccumulation of Potentially Toxic Elements (PTEs) by benthic invertebrates in estuarine sediments is poorly understood. We sampled and analysed PTEs in sediments and benthic invertebrates from five sites in the Skeena Estuary (British Columbia ...

Amazonian drought of 2023: Environmental conditions relevant to fishes

Journal of Fish Biology, EarlyView.
Abstract This paper provides a platform for the following studies within this Special Issue. ‘Ecophysiology of fishes in the two great tributaries of the Amazon in the Anthropocene’. It documents the water quality conditions and accompanying zooplankton community structure and biomass relative to fish health in the Rio Negro and Rio Solimões during the

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Photic-zone euxinia had a major role in the Devonian-Carboniferous boundary mass extinction

Communications Earth & Environment
Marine anoxia is widely proposed as a kill mechanism for the Devonian-Carboniferous boundary mass extinction commonly linked to the end-Devonian Hangenberg Crisis (~359.3 Ma), but the exact connections between primary drivers, marine redox conditions ...

Sediment microbial communities in long‐term wetland restorations within the Prairie Pothole Region of the United States

Restoration Ecology, EarlyView.
Hydrologic wetland restoration in the Prairie Pothole Region is a common management practice to facilitate habitat and ecosystem recovery after degradation or drainage. Little is known about the recovery of sediment microbial communities relative to other organisms, such as vegetation, fish, and macroinvertebrates, even though they are critical for ...

Borealization of the Arctic Ocean in Response to Anomalous Advection From Sub-Arctic Seas

Frontiers in Marine Science, 2020
An important yet still not well documented aspect of recent changes in the Arctic Ocean is associated with the advection of anomalous sub-Arctic Atlantic- and Pacific-origin waters and biota into the polar basins, a process which we refer to as ...
