Complex interactions between marine sponges and their symbiotic microbial communities
Complex interactions marine sponges symbiotic microbial communities
2014/4/4
To investigate the importance of symbiont-derived nutrition to host sponges, we coupled manipulative shading experiments with stable isotope analyses of isolated symbiont and host cell fractions. Expe...
Identification of phytodetritus-degrading microbial communities in sublittoral Gulf of Mexico sands
phytodetritus-degrading microbial communities Mexico sands
2014/4/18
We identified microbial taxa that catalyze phytodetritus degradation and denitrification in permeable coastal
sediments of the northeast Gulf of Mexico. Stable isotope probing experiments were used t...
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...
Metabolic and structural response of hyporheic microbial communities to variations in supply of dissolved organic matter
hyporheic microbial communities Metabolic
2014/5/21
Hyporheic sediment bacterial communities were exposed to dissolved organic matter (DOM) from a variety of
sources to assess the interdependence of bacterial metabolism and community composition. Expe...
