The interplay between bacterial community composition and the environment determining function of inland water bacteria
bacterial community composition the environment determining function inland water bacteria
2014/4/16
We hypothesized that habitats differing in water flow regime would differ in bacterial function either because of differences in the local environment, in bacterial community composition (BCC), or in ...
Methanogenic pathway, 13 C isotope fractionation, and archaeal community composition in the sediment of two clear-water lakes of Amazonia
isotope fractionation archaeal community composition
2014/4/16
We studied the methanogenic pathway and archaeal community composition in the sediment of two clearwater lakes, Lake Batata and Lake Mussura, in Amazonia. We measured CH4 production and d13

Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...
