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 s...
