Abstract Eutrophication in the Baltic Sea has caused an imbalance in the inorganic nitrogen (N) to phosphorus (P) ratio, leaving excess phosphate (PO4) after the phytoplankton spring bloom that terminates after N depletion. Using monitoring data, we demonstrated that the PO4 concentration has continued to increase in the outermost Gulf of Finland ...

The continuous plankton recorder survey: A long-term, basin-scale oceanic time series [PDF]
In the 1920s, before the advent of echo sounders, fishery biologists were greatly concerned with assisting the fisherman to locate schools of pelagic fish.

Feeding ecology of juvenile Pacific salmon (Oncorhynchus spp.) in a northeast Pacific fjord: diet, availability of zooplankton, selectivity for prey, and potential competition for prey resources [PDF]
We investigated the feeding ecology of juvenile salmon during the critical early life-history stage of transition from shallow to deep marine waters by sampling two stations (190 m and 60 m deep) in a northeast Pacific fjord (Dabob Bay, WA) between May ...

Abstract In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact ...

Two educational posters featuring a collage of various plankton taxa discovered in the Oslofjord, Norway. The photographs were taken in 2023 close to the Biological Station “Biologen” (Drøbak, University of Oslo). The darkfield images were captured using a CPICS underwater microscope, while the lightfield images were obtained using a Planktoscope.

Small‐scale thermal habitat variability may not determine seagrass resilience to climate change
Abstract Seagrass ecosystems are integral components of coastal marine environments, but they face global threats from climate change. The ability of seagrass to withstand these challenges depends on trait variation among individuals, which is influenced by genetic background and plasticity.

Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Linking stage-resolved population models with field observations: an integrated approach on population dynamics of Pseudocalanus elongatus in the German Bight. [PDF]
The population dynamics of Pseudocalanus elongatus have been investigated within the framework of the GLOBEC-Germany project to gain a better understanding of its life cycle and population dynamics and to estimate secondary production in the North Sea.
