Arising from Y. Zhao et al. Nature 494, 357–360 (2013). The recent findings of abundant SAR11 viruses by Zhao et al. are intriguing, and add new insight into the on-going discussion of why SAR11 bacteria are highly successful in the pelagic ocean. On the basis of high SAR11 virus abundance, Zhao et al. claim that SAR11 bacteria are competition specialists.(More)
Planctomycetes form a deep branching and distinct phylum of the domain Bacteria, and represent a fascinating group due to their unusual features such as intracellular compartmentalization and lack of peptidoglycan in their cell walls. The phylum Planctomycetes was described already in 1924, but still the diversity of this phylum represents an enigma and(More)
Trophic mechanisms that can generate biodiversity in food webs include bottom-up (growth rate regulating) and top-down (biomass regulating) factors. The top-down control has traditionally been analyzed using the concepts of "Keystone Predation" (KP) and "Killing-the-Winner" (KtW), predominately occuring in discussions of macro- and micro-biological ecology,(More)
We investigated the relationship between viruses and co-occurring bacterial communities in the Sognefjord, a deep-silled fjord in Western Norway. A combination of flow cytometry and automated ribosomal intergenic spacer analysis (ARISA) was used to assess prokaryote and viral abundances, and bacterial diversity and community composition, respectively, in(More)
