Abstract Flow cytometry measures the optical properties of individual cells and has become essential for enumerating and characterizing marine phytoplankton. Yet systematic comparison of measurements across instruments remains limited, hampering data comparison across laboratories and long‐term time series.

The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Clade-Specific Quantitative Analysis of Photosynthetic Gene Expression in Prochlorococcus. [PDF]
Newly designed primers targeting rbcL (CO2 fixation), psbA (photosystem II) and rnpB (reference) genes were used in qRT-PCR assays to assess the photosynthetic capability of natural communities of Prochlorococcus, the most abundant photosynthetic ...

Acclimation and stress response of Prochlorococcus to low salinity
Prochlorococcus is an obligate marine microorganism and the dominant autotroph in tropical and subtropical open ocean. However, the salinity range for growing and response to low salinity exposure of Prochlorococcus are still unknown.

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Coexistence of Dominant Marine Phytoplankton Sustained by Nutrient Specialization
Prochlorococcus and Synechococcus are the two dominant picocyanobacteria in the low-nutrient surface waters of the subtropical ocean, but the basis for their coexistence has not been quantitatively demonstrated.

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 ...

Phytoplankton Size Structure Controls the Bio‐Optical Anomaly of Antarctic Waters
Abstract Phytoplankton in the Southern Ocean strongly influence global biogeochemical cycles, but the region's remoteness limits in situ monitoring. Satellite ocean color enables synoptic monitoring of phytoplankton dynamics by retrieving chlorophyll‐a concentration (Chl‐a).

Graphical Abstract and Lay Summary Intracellular nucleases, depicted as blue circles in a nucleosome, hydrolyze phosphodiester bonds, repair damaged DNA using DNA base excision repair (BER), mismatch repair (MMR), and homologous recombination (HR), and are involved in DNA replication.
