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 …

Competition between microbial species is a product of, yet can lead to a reduction in, the
microbial diversity of specific habitats. Microbial habitats can resemble ecological …

Abstract The Tara Oceans expedition (2009–2013) sampled contrasting ecosystems of the
world oceans, collecting environmental data and plankton, from viruses to metazoans, for …

Marine viruses play a key role in regulating phytoplankton populations, greatly affecting the
biogeochemical cycling of major nutrients in the ocean. Resistance to viral infection has …

Background Bathycoccus prasinos is an extremely small cosmopolitan marine green alga
whose cells are covered with intricate spider's web patterned scales that develop within the …

Since the discovery 2–3 decades ago that viruses of microbes are abundant in marine
ecosystems, viral ecology has grown increasingly to reach the status of a full scientific …

Because viruses of eukaryotic algae are incredibly diverse, sweeping generalizations about
their ecology are rare. These obligate parasites infect a range of algae and their diversity …

Tiny photosynthetic microorganisms that form the picoplankton (between 0.3 and 3 μm in
diameter) are at the base of the food web in many marine ecosystems, and their adaptability …

Phytoplankton community structure is shaped by both bottom–up factors, such as nutrient
availability, and top–down processes, such as predation. Here we show that marine viruses …

Viruses span an impressive size range, with genome length varying a thousandfold and
virion volume nearly a millionfold. For cellular organisms the scaling of traits with size is a …
