High bacterivory by the smallest phytoplankton in the North Atlantic Ocean
Mikhail V. Zubkov,Glen A. Tarran +1 more
TL;DR: Evidence is presented that small algae carry out 40–95% of the bacterivory in the euphotic layer of the temperate North Atlantic Ocean in summer, suggesting the global significance of mixotrophy and reveals that even the smallest algae have less dependence on dissolved inorganic nutrients than previously thought.
Journal ArticleDOI
The role of mixotrophic protists in the biological carbon pump
Aditee Mitra,Kevin J. Flynn,JoAnn M. Burkholder,Terje Berge,Albert Calbet,John A. Raven,Edna Granéli,Patricia M. Glibert,Per Juel Hansen,Diane K. Stoecker,T. Frede Thingstad,Urban Tillmann,Selina Våge,Susanne Wilken,Mikhail V. Zubkov +14 more
TL;DR: It is shown how the exclusion of an explicit mixotrophic component in studies of the pelagic microbial communities leads to a failure to capture the true dynamics of the carbon flow, and recommended inclusion of multi-nutrient mixotroph models within ecosystem studies.
Journal ArticleDOI
High rate of uptake of organic nitrogen compounds by Prochlorococcus cyanobacteria as a key to their dominance in oligotrophic oceanic waters.
TL;DR: Direct evidence that marine cyanobacteria take up organic nitrogen compounds in situ at high rates is reported, providing a mechanism for Prochlorococcus' competitive dominance over both strictly autotrophic algae and other bacteria in oligotrophic regions sustained by nutrient remineralization via a microbial loop.
Journal ArticleDOI
Reconciliation of the carbon budget in the ocean’s twilight zone

TL;DR: It is found that prokaryotes are responsible for 70 to 92 per cent of the estimated remineralization in the twilight zone despite the fact that much of the organic carbon is exported in the form of large, fast-sinking particles accessible to larger zooplankton.
