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 ...

Abstract Boreal lakes are generally seen as sources of carbon dioxide (CO2) to the atmosphere, even though a part of them are periodically undersaturated with CO2 and have the potential to be net‐autotrophic. This undersaturation is the result of photosynthetic activity by phytoplankton, especially flagellated species like Gonyostomum semen, which form

The role of light quality and species richness in shaping phytoplankton communities
Abstract In natural water bodies, the light spectrum changes with depth, often toward a higher proportion of blue light. While spectral niche partitioning and functional redundancy are important concepts, our understanding of how light spectrum changes affect phytoplankton communities is limited.

Abstract Assessments of lake gross primary production (GPP) and respiration (R) and their balance (net ecosystem production, NEP) have been limited to specific watersheds and a limited number of lakes, often along narrow environmental gradients. This is because conventional approaches require either lengthy incubations or the deployment of monitoring ...

On the fundamental additive modes of ocean color absorption
Abstract Previous principal component analyses of ocean color absorption coefficient spectra aλ$$ a\left(\lambda \right) $$ have shown the variation in these data is captured by a few eigenfunctions. Here, we perform an unsupervised, non‐negative matrix factorization (NMF) of aλ$$ a\left(\lambda \right) $$ to derive their fundamental and physically ...

Abstract Anthropogenic pressures like ocean warming, acidification, rising N : P ratios, and marine heatwaves (MHWs) are affecting eukaryotic plankton diversity, though their combined impacts are rarely studied. To address this, we conducted a mesocosm experiment on a North Sea plankton community, testing the influence of a MHW under ambient and future
