Phytoplankton community structure in the Western Subarctic Gyre of the Pacific Ocean during summer determined by a combined approach of HPLC-pigment CHEMTAX and metabarcoding sequencing

Frontiers in Marine Science, 2023
The Western Subarctic Gyre (WSG) is a cyclonic upwelling gyre in the northwest subarctic Pacific, which is a region with a high concentration of nutrients but low chlorophyll.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Cryptophyte farming by symbiotic ciliate host detected in situ [PDF]

Proceedings of the National Academy of Sciences, 2016
Significance Symbioses between marine plankton species are diverse and widespread both spatially and taxonomically. However, the nature and function of such relationships in natural assemblages are severely underexplored due to technical challenges. Consequently, as an example, the relationship between the ciliate

A test of the gleaner–opportunist trade‐off among photosynthetic traits in cryptophyte algae

Ecosphere
As photosynthetic producers, phytoplankton form the foundation of aquatic food webs. Understanding the relationships among photosynthetic traits in phytoplankton is essential to revealing how diversification of these traits allows phytoplankton to ...

Variation in ω-3 and ω-6 Polyunsaturated Fatty Acids Produced by Different Phytoplankton Taxa at Early and Late Growth Phase

Biomolecules, 2020
Phytoplankton synthesizes essential ω-3 and ω-6 polyunsaturated fatty acids (PUFA) for consumers in the aquatic food webs. Only certain phytoplankton taxa can synthesize eicosapentaenoic (EPA; 20:5ω3) and docosahexaenoic acid (DHA; 22:6ω3), whereas all ...

Bacterial Contribution to Hydrogen Peroxide Decomposition in Lake Erie Cyanobacterial Harmful Algal Bloom Communities Is Dependent on Bloom Stage

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
A seasonal time series metatranscriptome dataset suggests that neutralising hydrogen peroxide in Microcystis blooms requires a complex division of labour that is further complicated by seasonality and bloom development. ABSTRACT Cyanobacterial harmful algal blooms (cHABs) are expanding globally and often involve toxin‐producing species such as ...

Putative genome features of relic green alga-derived nuclei in dinoflagellates and future perspectives as model organisms

Communicative & Integrative Biology, 2020
Nucleomorphs, relic endosymbiont nuclei, have been studied as a model to elucidate the evolutionary process of integrating a eukaryotic endosymbiont into a host cell organelle.

Open Ocean Biogeochemical Impacts of Extreme Terrestrial Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates.

Nutritional content of phytoplankton communities under ice

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract The effects of winter environmental conditions on lake ecology can be highly variable. Ice and overlying snow isolate the water below, impeding exchange of materials among water, atmosphere, and the watershed. Even with these limitations, biological communities under the ice can persist, where cold‐tolerant taxa can be especially abundant ...
