Margalef's mandala, Prochlorococcus, and geoengineering
Ocean phytoplankton played a central role in oxygenating our planets atmosphere billions of years ago. Hence these early geoengineers were crucial for the evolution of life on Earth. Their modern-day ancestor, the marine cyanobacterium Prochlorococcus, is the most abundant photosynthetic cell on the planet.

Photoinactivation of Photosystem II in Prochlorococcus and Synechococcus
The marine picocyanobacteria Synechococcus and Prochlorococcus numerically dominate open ocean phytoplankton. Although evolutionarily related they are ecologically distinct, with different strategies to harvest, manage and exploit light. We grew representative strains of Synechococcus and Prochlorococcus and tracked their susceptibility to ...

Bias in culture-independent assessments of microbial biodiversity in the global ocean [PDF]
On the basis of 16S rRNA gene sequencing, the SAR11 clade of marine bacteria has almost universal distribution, being detected as abundant sequences in all marine provinces. Yet SAR11 sequences are rarely detected in fosmid libraries, suggesting that the

Characteristics of Wetting-Induced Bacteriophage Blooms in Biological Soil Crust. [PDF]
Biological soil crusts (biocrusts) are photosynthetic "hot spots" in deserts and cover ∼12% of the Earth's terrestrial surface, and yet they face an uncertain future given expected shifts in rainfall events.

This study reveals an unexpectedly simplified, Brachyspira‐dominated gastrointestinal microbiota in pompano dolphinfish from both neritic and deep‐sea habitats of the South China Sea. Environmental DNA and functional analyses suggest these fish may acquire potential pathogens in anthropogenically influenced coastal waters and transport them offshore ...

STOCHASTIC DYNAMICS OF TWO PICOPHYTOPLANKTON POPULATIONS IN A REAL MARINE ECOSYSTEM [PDF]
A stochastic reaction-diffusion-taxis model is analyzed to get the stationary distribution along water column of two species of picophytoplankton, that is picoeukaryotes and Prochlorococcus.

Abstract Seawater contains small biomolecules, or metabolites, that are highly labile components of dissolved organic matter (DOM). Marine microbes interact by exchanging metabolites, thus shaping marine microbial ecology, DOM composition, and global carbon cycling.

Differential Activity of Coexisting Prochlorococcus Ecotypes
The abundance and widespread distribution of the unicellular cyanobacterium Prochlorococcus is attributed to its extensive genetic diversity. At least twelve distinct clades, or ecotypes, of Prochlorococcus have been discovered so far, and follow distinct distribution patterns over horizontal and vertical gradients in the oligotrophic ocean.

Abstract The Seychelles–Chagos Thermocline Ridge is an upwelling region in the western Indian Ocean, but its role in sinking particle flux remains unclear. We present sediment trap records (July 2022 to June 2024) at 1000 and 2500 m to reveal variations in particle flux and composition.
