Aquatic microbial ecosystems are generally assumed to function within a homogeneous environment in which nutrient dispersal is virtually instantaneous. Blackburn et al. (p. 2254) show that this is not so: Patches of nutrients, related to the release of fresh dissolved organic matter, form through the clustering of chemotactic bacteria. Simulations reveal that chemotaxis confers a significant growth advantage to bacteria, thus explaining why the phenotype is present in this environment.
