TL;DR: SILVA (from Latin silva, forest), was implemented to provide a central comprehensive web resource for up to date, quality controlled databases of aligned rRNA sequences from the Bacteria, Archaea and Eukarya domains.

TL;DR: The bacterioplankton response to a diatom bloom in the North Sea is investigated and a dynamic succession of populations at genus-level resolution is observed, revealing how planktonic species, despite their seemingly homogeneous habitat, can evade extinction by direct competition.

TL;DR: FISH with rRNA-targeted oligonucleotide probes was used to investigate the phylogenetic composition of bacterioplankton communities in several freshwater and marine samples, finding that Beta subclass proteobacteria constituted a dominant fraction in freshwater systems and members of the Cytophaga-Flavobacterium cluster were the most abundant group detected in the marine systems.

TL;DR: It is shown that instead, the anammox process (the anaerobic oxidation of ammonium by nitrite to yield N2) is mainly responsible for nitrogen loss in the OMZ waters of one of the most productive regions of the world ocean, the Benguela upwelling system.

TL;DR: This Review provides an update on the recent methodological improvements that have allowed more reliable quantification of microbial populations in situ in complex environmental samples, with a particular focus on the usefulness of group-specific probes in this era of ever-growing rRNA databases.
