Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference

Phytoplankton stimulation in frontal regions of Benguela upwelling filaments by internal factors

open access: yesFrontiers in Marine Science, 2016
Filaments are intrusions of upwelling water into the sea, separated from the surrounding water by fronts. Current knowledge explains the enhanced primary production and phytoplankton growth found in frontal areas by external factors like nutrient input ...

Zonation of bacterioplankton communities along aging upwelled water in the northern Benguela upwelling

open access: yesFrontiers in Microbiology, 2015
Upwelling areas are shaped by enhanced primary production in surface waters, accompanied by a well-investigated planktonic succession. Although bacteria play an important role in biogeochemical cycles of upwelling systems, little is known about bacterial

Reduced Reproductive Success of Western Baltic Herring (Clupea harengus) as a Response to Warming Winters

open access: yesFrontiers in Marine Science, 2021
Shallow estuaries, bays, and lagoons are generally considered hot spots of ocean productivity that often adjust rapidly to seasonal variations in atmospheric temperatures. During spring when biological reproductive processes begin in the temperate zones,

Investigating Hypoxic and Euxinic Area Changes Based on Various Datasets From the Baltic Sea

open access: yesFrontiers in Marine Science, 2022
The Baltic Sea is a coastal sea with the world’s largest anthropogenically induced hypoxic bottom area. Although hypoxia has periodically occurred during the sea’s 8,000-year history, the rapid rise in the population and intensified agriculture after ...

Atlantic multidecadal variability and the implications for North European precipitation

open access: yesEnvironmental Research Letters, 2022
The North Atlantic exhibits temperature variations on multidecadal time scales, summarized as the Atlantic multidecadal variability (AMV). The AMV plays an essential role for regional climate and is a key driver of the low-frequency variability in ...
