Many marine habitats, such as the surface and tissues of marine invertebrates, including corals, harbour diverse populations of microorganisms, which are thought to play a role in the health of their hosts and influence mutualistic and competitive interactions. Investigating the presence and stability of quorum sensing (QS) in these ecosystems may shed light on the roles and control of these bacterial communities.
Despite their importance for ecosystem functioning, little is known about the composition of active marine bacterioplankton communities. Hence, this study was focused on assessing the diversity of these communities in the southern North Sea and examining the impact of a phytoplankton spring bloom on the ambient bacterioplankton community. Community composition in and outside the bloom was assessed in 14 samples by pyrosequencing-based analysis of 16S rRNA gene amplicons generated from environmental RNA. The data set comprised of 211 769 16S rRNA gene sequences. Proteobacteria were the predominant phylogenetic group with Alphaproteobacteria and Gammaproteobacteria as the most abundant classes. Actinobacteria and Bacteroidetes were identified in minor abundances.

Inferring community dynamics of organohalide-respiring bacteria in chemostats by covariance of rdhA gene abundance
Ian P.G. Marshall, Mohammad F. Azizian, Lewis Semprini and Alfred M. Spormann
This study demonstrates a new approach to the analysis of communities of bacteria that dehalogenate organohalide pollutants. Genes encoding reductive dehalogenases are grouped into bacterial strains based on their covariance.
Weighing the deep continental biosphere
Sean McMahon and John Parnell
The question of how many microbes are on Earth continues to intrigue microbiologists. Whitman et al. (P Natl Acad Sci USA, 95, 1998, 6578) first estimated the number of prokaryotes and the total amount of their cellular carbon on earth. The current study by McMahon & Parnell provides a reappraisal of the continental subsurface biomass. The evidence from over 100 microbial population density measurements continues to support a deep continental biomass estimate of 1016–1017 g C, or 2–19% of Earth's total biomass. This abundant and widespread microbial activity in deep continental fractures and aquifers has important implications for biogeochemical cycling on Earth.
Virtual and Thematic Issues
Special Virtual Issue - FEMS Microbiology Ecology meets FEMS Microbiology Reviews
FEMS Microbiology Ecology has compiled a Virtual Issue that cross-links with the May 2013 Thematic Issue of FEMS Microbiology Reviews on Molecular Insights into Environmental Microbes. We have selected key papers from the archives of FEMS Microbiology Ecology to complement the topics of the review articles that reflect on the activity of microbes, ranging from life in symbiosis, commensalism, and syntrophy to life in soil, lakes and oceans.
