Heterotrophic nanoflagellates are an important consumer group within pelagic foodwebs and play a vital role in cycling carbon and nitrogen in the world's oceans. Most primary production passes either ...
We measured net planktonic community production (NCP), community respiration (CR), and gross primary production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
We determined the source of fatty acids in scleractinian corals by separately measuring and comparing thed13C values of fatty acids in zooxanthellae and coral hosts from two scleractinian coral specie...
We tested the hypothesis that nutrient sequestration and carbon flow through heterotrophic bacteria is relatively highest in oligotrophic systems and decreases with trophic state in 17 reservoirs in T...
Radioisotopes of six metals (54Mn, 55 Fe, 65 Zn, 109 Cd, 137 Cs, and 241Am) were used to assess the accumulation of these metals by five species of heterotrophic marine bacteria in laboratory cul...
We tested the role of immigration from the plankton on the structure of local surface-associated communities of ciliates and heterotrophic flagellates (HF) in flow cells fed with fresh riverine water...
Stamukhi lakes are vast but little-explored Arctic ecosystems. They occur throughout winter, spring, and early summer near large river inflows along the Arctic coastline, and are the result of freshwa...
Literature review and synthesis of growth rates of aquatic protists focused on the role of temperature in the formation of massive annual algal blooms in high-latitude ecosystems. Maximal growth rates...
We assessed growth dynamics of heterotrophic picoplankton and concentrations and turnover of dissolved protein, amino acids, and neutral monosaccharides in the Atlantic sector of the Southern Ocean in...
We investigated whether trophic repackaging of autotrophic picoplankton by phagotrophic protists is associated with an improvement in food quality for the metazooplankton Daphnia magna (i.e., whether ...
We investigated long-term trends (1965–2002) in dissolved inorganic nutrients in the tidal part of the Scheldt estuary (Belgium, The Netherlands). Annually averaged concentrations of dissolved silica...
To date no study exists that directly addresses changes in dynamics of heterotrophic bacteria in surface waters in relation to partial pressure of CO2 (pCO2 ). Therefore, we studied the effect of c...
We studied heterotrophic bacterial dynamics as part of the Southern Ocean Iron Experiment (SOFeX), January-February 2002. Two phytoplankton blooms were monitored following infusions with iron sulfate ...
Growth and feeding rates of four species of planktonic marine heterotrophic protists showed pronounced diel cycles. In most cases, rates were higher during the day and lower at night. However, for the...
