TL;DR: This work proposes the constant-diversity dynamics model, in which the diversity of prokaryotic populations is preserved by phage predation, and provides supporting evidence for this model from metagenomics, mathematical analysis and computer simulations.

TL;DR: A metabolic and taxonomic snapshot of microbes associated with the reef-building coral Porites astreoides is provided and presents a basis for understanding how coral-microbial interactions structure the holobiont and coral reefs.

TL;DR: The authors used pyrosequencing, a rapid and relatively inexpensive sequencing technology, to generate environmental genome sequences from two sites in the Soudan Mine, Minnesota, USA, which were adjacent to each other, but differed significantly in chemistry and hydrogeology.

TL;DR: The results suggest a model wherein functionally redundant microbial and viral taxa are cycling at the level of viral genotypes and virus-sensitive microbial strains, which contradicts theoretical models as well as the viral–microbial dynamics observed in simple ecosystems.

TL;DR: Metagenomic sequencing of DNA viruses from the feces of a healthy week-old infant revealed a viral community with extremely low diversity, dominated by phages, which likely influence the diversity and abundance of co-occurring microbes.
