Diatoms form a diverse and abundant group of photosynthetic protists that are essential
players in marine ecosystems. However, the microevolutionary structure of their populations …

Vitamin B 12 (cobalamin) can control phytoplankton development and community composition,
with around half of microalgal species requiring this vitamin for growth. B 12 dependency …

Cobalamin (vitamin B 12 ) is a cobalt-containing enzymatic cofactor involved in methionine
synthesis. Provided only by select bacteria and archaea in marine systems, this vitamin is …

Haptophyte microalgae are key contributors to microbial communities in many environments.
It has been proposed recently that members of this group would be virtually all dependent …

Marine plankton form complex communities of interacting organisms at the base of the food
web, which sustain oceanic biogeochemical cycles and help regulate climate. Although …

Diatoms, the main eukaryotic phytoplankton of the polar marine regions, are essential for
the maintenance of food chains specific to Arctic and Antarctic ecosystems, and are …

Diatoms, an evolutionarily successful group of microalgae, display high levels of intraspecific
genetic variability in natural populations. However, the contribution of various mechanisms …

Microbial communities in the world ocean are affected strongly by oceanic circulation, creating
characteristic marine biomes. The high connectivity of most of the ocean makes it difficult …

Marine microorganisms form complex communities of interacting organisms that influence
central ecosystem functions in the ocean such as primary production and nutrient cycling. …

Dinoflagellates are a diverse group of ecologically significant micro-eukaryotes that can serve
as a model system for plastid symbiogenesis due to their susceptibility to plastid loss and …
