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)
By adding a generic description of cost of resistance (COR) to the existing 'killing-the-winner' model, we show how this expands the model's explanatory power to include rank-abundance relationships in the host population. The model can predict a counter-intuitive relationship previously suggested in the literature, where abundant viruses are associated(More)
Pelagic prokaryote communities are often dominated by the SAR11 clade. The recent discovery of viruses infecting this clade led to the suggestion that such dominance could not be explained by assuming SAR11 to be a defense specialist and that the explanation therefore should be sought in its competitive abilities. The issue is complicated by the fact that(More)
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)
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)
