The biological pump is a process whereby CO2 in the upper ocean is fixed by primary
producers and transported to the deep ocean as sinking biogenic particles or as dissolved …

Recognition of the environmental role of photoheterotrophic bacteria has been one of the
main themes of aquatic microbiology over the last 15 years. Aside from cyanobacteria and …

The Cyanobacteria Prochlorococcus and Synechococcus account for a substantial fraction
of marine primary production. Here, we present quantitative niche models for these lineages …

The family Erythrobacteraceae, belonging to the order Sphingomonadales, class
Alphaproteobacteria, is globally distributed in various environments. Currently, this family …

Incubation (in vitro) and incubation-free (in situ) methods, each with their own advantages
and limitations, have been used to derive estimates of net community metabolism in the …

Recent discoveries suggest that photoheterotrophs (rhodopsin-containing bacteria (RBs)
and aerobic anoxygenic phototrophs (AAPs)) and chemoautotrophs may be significant for …

The majority of marine dissolved organic carbon (DOC) is resistant to biological degradation
and thus can remain in the water column for thousands of years, constituting carbon …

Large rivers are commonly regulated by damming, yet the effects of such disruption on
prokaryotic communities have seldom been studied. We describe the effects of the three …

Rice paddies are a significant source of the greenhouse gas methane, which mainly
originates from microbial activity. Methane generation in anaerobic systems involves …

The Roseobacter group and SAR11 clade constitute high proportions of the marine
bacterioplankton, but only scarce information exists on the abundance of distinct populations …
