We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
Living at the border: A community and single-cell assessment of lake bacterioneuston activity
Living at the border A community single-cell assessment lake bacterioneuston activity
2014/4/17
We assessed the physicochemical properties of the surface microlayer (SML: first 900mm) and its underlying water (ULW: 0.2–0.5-m depth) and compared the composition and activity of their bacterial com...
Influence of cell cycle phase on calcification in the coccolithophoreEmiliania huxleyi
cell cycle phase calcification coccolithophore Emiliania huxleyi
2014/4/21
Calcification of the cosmopolitan coccolithophore speciesEmiliania huxleyiwas investigated in relation to the cell division cycle with the use of batch cultures. With a 12 : 12 h light : dark cycle, t...
Bacterial release of dissolved organic matter during cell growth and decline: Molecular origin and composition
Bacterial release dissolved organic matter cell growth and decline Molecular origin and composition
2014/5/5
Heterotrophic bacterial growth and the chemical composition of dissolved organic matter (DOM) produced by bacteria from freshwater and marine environments were monitored during experiments with artifi...
Effect of pH on growth, cell volume, and production of freshwater ciliates, and implications for their distribution
pH on growth cell volume production freshwater ciliates
2014/5/4
We investigated the effect of pH on growth, cell volume, and production of the freshwater ciliates Urotricha farcta, U. furcata, and U. castalia in laboratory cultures with Cryptomonas sp. as food. Ov...
Trophic significance of solitary cells of the prymnesiophyte Phaeocystis globosa depends on cell type
Trophic significance solitary cells prymnesiophyte Phaeocystis globosa depends cell type
2014/5/4
With the use of five different isolates of Phaeocystis globosa solitary cells from the North Sea, we conducted experiments to reveal whether grazing and development of the nauplii of the calanoid cope...
The biological and biogeochemical consequences of phosphate scavenging onto phytoplankton cell surfaces
The biological and biogeochemical consequences phosphate scavenging phytoplankton cell surfaces
2014/5/13
Phytoplankton carbon (C) and nitrogen (N) content is commonly normalized to phosphorus (P) quotas as Redfield C:N: P ratios. We examined how surface-bound P pools affect Redfield stoichiometry and P u...
Diel variations in the photosynthetic parameters of Prochlorococcus strain PCC 9511: Combined effects of light and cell cycle
Diel variations photosynthetic parameters Prochlorococcus strain PCC 9511 light and cell cycle
2014/5/9
We examined the mechanisms related to the diel variations in the parameters of the relationship between the rate of carbon fixation of phytoplankton and irradiance (P vs. E curve). Our goal was to und...
Bioluminescent response of the dinoflagellate Lingulodinium polyedrum to developing flow: Tuning of sensitivity and the role of desensitization in controlling a defensive behavior of a planktonic cell
Bioluminescent response dinoflagellate Lingulodinium polyedrum developing flow Tuning of sensitivity desensitization controlling a defensive behavior planktonic cell
2014/5/9
Dinoflagellate bioluminescence is believed to serve a defensive function, decreasing grazing at night. Previous characterization of bioluminescence stimulated by fully developed flows might have under...
