An experimental investigation of the evolution of dispersiveness was carried out using two strains of Eschericia coli: one growing homogeneously (i.e., dispersed growth) in liquid medium in a test-tube culture, the other growing with weak attachment to test-tube walls. Experiments were designed to explore the conditions under which the dispersive or adhesive (resident) traits of bacterial cells can evolve, with a particular focus on the trade-off of the advantage of avoiding intraspecific competition versus the ability to reduce density-independent mortality. Experimental results suggest that dispersiveness of a bacterial population can change through selection of a mutant with higher fitness caused by either avoiding intraspecific competitive pressure or by reducing mortality, in a manner dependent on prevailing ecological conditions.
