One-quarter of photosynthesis-derived carbon on Earth rapidly cycles through a set of short-
lived seawater metabolites that are generated from the activities of marine phytoplankton …

Ecosystems are controlled by 'bottom-up'(resources) and 'top-down'(predation) forces. Viral
infection is now recognized as a ubiquitous top-down control of microbial growth across …

Gene exchange between viruses and their hosts acts as a key facilitator of horizontal gene
transfer and is hypothesized to be a major driver of evolutionary change. Our understanding …

Bacteria–phage coevolution, the reciprocal evolution between bacterial hosts and the
phages that infect them, is an important driver of ecological and evolutionary processes in …

The discovery of eukaryotic giant viruses has transformed our understanding of the limits of
viral complexity, but the extent of their encoded metabolic diversity remains unclear. Here …

BACKGROUND Marine ecosystems are composed of a diverse array of life forms, the
majority of which are unicellular—archaea, bacteria, and eukaryotes. The power of these …

The Arctic marine biome, shrinking with increasing temperature and receding sea-ice cover,
is tightly connected to lower latitudes through the North Atlantic. By flowing northward …

Emiliania huxleyi is a model coccolithophore micro-alga that generates vast blooms in the
ocean. Bacteria are not considered among the major factors influencing coccolithophore …

Marine viruses are considered to be major ecological, evolutionary, and biogeochemical
drivers of the marine environment, responsible for nutrient recycling and determining …

Unicellular, planktonic, prokaryotic and eukaryotic photoautotrophs (phytoplankton) have an
ancient evolutionary history on Earth during which time they have played key roles in the …
