Ocean viruses are abundant and infect 20–40% of surface microbes. Infected cells, termed
virocells, are thus a predominant microbial state. Yet, virocells and their ecosystem impacts …

The photosynthetic picocyanobacteria Prochlorococcus and Synechococcus are models for
dissecting how ecological niches are defined by environmental conditions, but how …

The role of bottom‐up (nutrient availability) and top‐down (grazers and viruses mortality)
controls on tropical bacterioplankton have been rarely investigated simultaneously from a …

Bacterioplankton play a pivotal role in marine ecosystems. However, their temporal
dynamics and underlying control mechanisms are poorly understood in tropical regions …

The North Pacific Subtropical Gyre (NPSG) is one of the largest biomes on Earth, with the
cyanobacterium Prochlorococcus being the most abundant primary producer year-round …

Over the past few decades, the Arctic region has been strongly affected by global warming,
leading to increased sea surface temperatures and melting of land and sea ice. Marine …

Introduction Marine viruses regulate microbial population dynamics and biogeochemical
cycling in the oceans. The ability of viruses to manipulate hosts' metabolism through the …

Temperate coastal marine waters are often thermally stratified from spring through fall but
can be dynamic and disrupted by tidal currents and wind‐driven upwelling. These mixing …

Viruses are abundant in the ocean and influence both the composition of marine
communities and biogeochemical cycles. Despite their high abundance, production rates of …

Virioplankton is a key component of marine biosphere in maintaining diversity of
microorganisms and stabilizing ecosystems. They also greatly contribute to nutrient recycles …
