Physical Basis of Prey Capture by Marine Heterotrophic Nanoflagellates
Physical Basis Prey Capture Marine Heterotrophic Nanoflagellates
2015/8/14
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 ...
Seasonal dynamics of autotrophic and heterotrophic plankton metabolism and PCO2 in a subarctic Greenland fjord
Biological metabolic kinetics Greenland fjord
2014/10/16
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...
Production of dissolved organic matter by phytoplankton and its uptake by heterotrophic prokaryotes in large tropical lakes
Production of dissolved organic matter by phytoplankton heterotrophic prokaryotes large tropical lakes
2014/7/10
In pelagic ecosystems, phytoplankton extracellular release can extensively subsidize the heterotrophic prokaryotic carbon demand. Time-course experiments were carried out to quantify primary productio...
Heterotrophic and autotrophic assimilation of fatty acids by two scleractinian corals, Montastraea faveolataandPorites astreoides
Heterotrophic autotrophic assimilation fatty acids two scleractinian corals Montastraea faveolata Porites astreoides
2014/4/8
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...
The relative importance of heterotrophic bacteria to pelagic ecosystem dynamics varies with reservoir trophic state
heterotrophic bacteria pelagic ecosystem dynamics varies reservoir trophic state
2014/4/17
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...
Metal accumulation by heterotrophic marine bacterioplankton
heterotrophic marine bacterioplankton Metal accumulation
2014/4/16
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...
Role of dispersal in shaping communities of ciliates and heterotrophic flagellates within riverine biofilms
Role of dispersal heterotrophic flagellates
2014/4/17
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...
Microbial community diversity and heterotrophic production in a coastalArctic ecosystem: A stamukhi lake and its source waters
Microbial community diversity heterotrophic production coastalArctic ecosystem stamukhi lake source waters
2014/4/21
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...
Does low temperature constrain the growth rates of heterotrophic protists? Evidence and implications for algal blooms in cold waters
low temperature growth rates of heterotrophic protists Evidence and implications algal blooms cold waters
2014/4/23
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...

Different coupling of dissolved amino acid protein carbohydrate turnover heterotrophic picoplankton production Southern Ocean in austral summer and fall
2014/4/22
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...
Trophic upgrading of autotrophic picoplankton by the heterotrophic nanoflagellate Paraphysomonas sp.
Trophic upgrading autotrophic picoplankton heterotrophic nanoflagellate Paraphysomonas sp.
2014/5/4
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 ...
