Variations in the optical properties of a particle suspension associated with viral infection of marine bacteria
Variations particle suspension associated marine bacteria
2014/4/17
A laboratory experiment was conducted to examine the temporal dynamics of the particle size distribution
(PSD) and associated optical variability caused by viral infection of marine heterotrophic bac...
Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates)
zooplankton-mediated trophic marine microbial food
2014/4/17
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial
communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a
c...
Vitamin B12 and cobalt cycling among diatoms and bacteria in Antarctic sea ice microbial communities
Vitamin B12 cobalt cycling among diatoms
2014/4/21
Within McMurdo Sound’s annual sea ice, assimilation and concentrations of vitamin B12 (cobalamin),
microbial community productivity, and biomass were examined among three 100-m2
quadrats where light...
Importance of detrital algae, bacteria, and organic matter to littoral microcrustacean growth and reproduction
Importance of detrital algae bacteria organic matter

Cumulative incorporation of radiolabeled algal (NaH14
CO3) and bacterial (14
C-acetate) carbon associated with
benthic organic matter (BOM) was measured at timed intervals to determine the relative...
Nitrogen incorporation and retention by bacteria, algae, and fauna in a subtropical intertidal sediment: An in situ 15N-labeling study
Nitrogen incorporation retention by bacteria
2014/4/22
We performed a 15N-labeling study to investigate nitrogen incorporation and retention by the benthic
microbial community (bacteria and benthic microalgae) and fauna in the intertidal sediment of the ...
Distribution of planktonic aerobic anoxygenic photoheterotrophic bacteria in the northwest Atlantic
anoxygenic photoheterotrophic bacteria northwest Atlantic
2014/4/23
Aerobic anoxygenic photoheterotrophic (AAP) bacteria can use both dissolved organic matter and light for energy
production, but their photosynthesis does not produce oxygen. We measured AAP bacterial...
Distribution of viruses and bacteria in relation to diagenetic activity in an estuarine sediment
viruses bacteria sediment
2014/5/21
The distribution of viruses and bacteria was investigated in relation to bacterial sulfate reduction and total respiration (production of dissolved inorganic carbon, [DIC]) in a coastal sediment. Vira...
