abstract：:Bacterial diversity is believed to be controlled both by bottom-up and top-down mechanisms such as nutrient competition, predation and viral lysis. We hypothesise that lytic viruses create trophic niches within bacterial communities, and thus primarily control richness and evenness, while substrate composition primari...
