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 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...
Sterol composition of dinoflagellates: Different abundance and composition in heterotrophic species and resting cysts
4α-methyl sterol autotrophic dinoflagellate heterotrophic dinoflagellate resting cyst motile cell
2017/8/9
The motile cells of the autotrophic dinoflagellates Peridinium umbonatum var. inaequale, Akashiwo sanguinea, Scrippsiella tinctoria, and Prorocentrum micans commonly contain five major sterols: choles...
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...
