Whether a small cell, a small genome or a minimal set of chemical reactions with self-
replicating properties, simplicity is beguiling. As Leonardo da Vinci reportedly said,'simplicity …

SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated
population size of 2.4× 1028 cells—approximately 25% of all plankton. They are found …

Reductive genomic evolution, driven by genetic drift, is common in endosymbiotic bacteria.
Genome reduction is less common in free-living organisms, but it has occurred in the …

In the surface ocean, phytoplankton transform inorganic substrates into organic matter that
fuels the activity of heterotrophic microorganisms, creating intricate metabolic networks that …

Ocean warming occurs every year in seasonal cycles that can help us to understand long-
term responses of plankton to climate change. Rhythmic seasonal patterns of microbial …

Microorganisms play crucial roles in maintaining ecosystem stability. The last two decades
have witnessed an upsurge in studies on marine microbial community composition using …

Black Queen (BQ) functions are biological processes that yield neither purely private nor
purely public products. This partitioning of benefits, also called 'leakiness', can produce …

Abstract The Hawaii Ocean Time-series (HOT) programme has been tracking microbial and
biogeochemical processes in the North Pacific Subtropical Gyre since October 1988. The …

ABSTRACT SAR11 is an ancient and diverse clade of heterotrophic bacteria that are
abundant throughout the world's oceans, where they play a major role in the ocean carbon …

Chemoheterotrophic marine bacteria of the SAR11 clade are Earth's most abundant
organisms. Following the first cultivation of a SAR11 bacterium,'Candidatus Pelagibacter …
