Phaeocystis is a cosmopolitan, bloom-forming phytoplankton genus that contributes
significantly to global carbon and sulfur cycles. During blooms, Phaeocystis species produce …

Phycosphere bacteria can regulate the dynamics of different algal blooms that impact
marine ecosystems. Phaeocystis globosa can alternate between solitary free-living cells and …

Iron is an essential nutrient for all microorganisms of the marine environment. Iron limitation
of primary production has been well documented across a significant portion of the global …

Phytoplankton and their associated microbiomes of heterotrophic bacteria are foundational
to primary production, energy transfer, and biogeochemical cycling in aquatic systems …

Anoxic marine zones (AMZs) are host to anaerobic metabolisms that drive losses of
bioavailable nitrogen from the ocean. The discovery of active nitrite-oxidising bacteria …

Abstract Pseudoalteromonas (BB2-AT2) is a ubiquitous marine heterotroph, often
associated with labile organic carbon sources in the ocean (eg phytoplankton blooms and …

In the Subantarctic sector of the Southern Ocean, vertical entrainment of iron (Fe) triggers
the seasonal productivity cycle but diminishing physical supply during the spring to summer …

The scarcity of iron limits phytoplankton growth in large areas of the global ocean.
Zooplankton may contribute to the cycling of iron via excretion and egestion. Despite …

Interactions between bacteria and microalgae are important for the functioning of aquatic
ecosystems, yet interactions based on the biodiversity of these two taxonomic domains have …

At the sub-Antarctic Prince Edward Islands (PEIs) in the Southern Ocean, the Island Mass
Effect (IME) plays an important role in maintaining an ecosystem able to support diverse …
