In situ associations between marine photosynthetic picoeukaryotes and potential parasites - a role for fungi? [PDF]
Photosynthetic picoeukaryotes (PPEs) are important components of the marine picophytoplankton community playing a critical role in CO2 fixation but also as bacterivores, particularly in the oligotrophic gyres.

Abstract The California Current System (CCS) is characterized by dynamic coastal upwelling that profoundly influences plankton community structure and diversity and that leads to the emergence of large diatoms nearshore. This study presents a high‐resolution biogeochemical model of the CCS, coupling the Darwin ecosystem model with the Regional Ocean ...

Picoheterotroph (Bacteria and Archaea) biomass distribution in the global ocean [PDF]
We compiled a database of 39 766 data points consisting of flow cytometric and microscopical measurements of picoheterotroph abundance, including both Bacteria and Archaea.

Delineating Marine Planktonic Habitats Through the Biogeochemical‐Argo Array Data
Abstract Phytoplankton play a crucial role in regulating marine biogeochemical pathways but studying their spatial and temporal dynamics often requires extensive and laborious oceanographic expeditions. Here, we report a novel use of Biogeochemical‐Argo data to delineate planktonic habitats in the Tropical North Atlantic Ocean (TNA).

Environmental modulation of the plankton community composition and size-structure along the eutrophic intertidal coast of the Río de la Plata estuary, Argentina [PDF]
In this study we investigated the spatial distribution of the plankton community, bacterio-, phyto-, and zooplankton, in relation with environmental conditions along the intertidal coast of the Río de la Plata estuary, Argentina. Plankton was analyzed in

Abstract Increasing our knowledge about the structure and metabolism of the microbial plankton community in coastal upwelling systems is essential for efficiently managing the resources of these highly productive ecosystems. Here we explore seasonal variations of this community in the NW Iberian coastal upwelling system by measuring variables informing

Effects of microzooplankton and mixotrophy in an experimental planktonic food web [PDF]
Microzooplankton have received increased attention as an important trophic link between the microbial loop and calanoid copepods. On the basis of food size spectra overlap in some microzooplankton groups and calanoid copepods, however, such ...

Seasonal Changes in Marine Archaeal Tetraether Lipid Export Depth Linked to Net Primary Productivity
Abstract Marine ammonia oxidizing archaea (AOA) produce isoprenoid glycerol dibiphytanyl glycerol tetraethers (GDGTs) which form the basis of seawater temperature proxy TEX86. Although most studies use TEX86 for sea surface temperature (SST) reconstructions, maximum GDGT production occurs at and below the nitracline. Moreover, sedimentary GDGT‐2/GDGT‐3

Interannual Variation in Phytoplankton Primary Production at a Global Scale [PDF]
We used the NASA Ocean Biogeochemical Model (NOBM) combined with remote sensing data via assimilation to evaluate the contribution of four phytoplankton groups to the total primary production.

Abstract Rapid warming in the Arctic have influenced the ecological and biogeochemical systems in the Arctic Ocean, particularly the phytoplankton community that plays a fundamental role in food webs and carbon cycle. Our 10‐yr study found an abrupt change in the phytoplankton community in the western Arctic Ocean basin between 2008 and 2018.
