The “biological pump” is the process by which photosynthetically-produced organic matter in
the ocean descends from the surface layer to depth by a combination of sinking particles …

Culture-dependent and-independent studies have found that prokaryotic assemblages are
quite diverse in aquatic habitats and contain representatives of virtually all of the roughly 40 …

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

Communities of microscopic plant life, or phytoplankton, dominate the Earth's aquatic
ecosystems. This important new book by Colin Reynolds covers the adaptations, physiology …

Microbes have central roles in ocean food webs and global biogeochemical processes, yet
specific ecological relationships among these taxa are largely unknown. This is in part due …

Very little is known about growth rates of individual bacterial taxa and how they respond to
environmental flux. Here, we characterized bacterial community diversity, structure and the …

Bacterioplankton (bacteria and archaea) are indispensable regulators of global element
cycles owing to their unique ability to decompose and remineralize dissolved organic matter …

Predation in aquatic microbial food webs is dominated by phagotrophic protists, yet these
microorganisms are still understudied compared to bacteria and phytoplankton. In pelagic …

Abstract The Humboldt Current System (HCS) is one of the most productive marine
ecosystems on earth. It extends along the west coast of South America from southern Chile …

The marine ecosystem of the West Antarctic Peninsula (WAP) extends from the
Bellingshausen Sea to the northern tip of the peninsula and from the mostly glaciated coast …
