Flavobacterium columnare colony morphotype dynamics (as mean colony forming units in log scale) under starvation in distilled water (left) and in lake water (right) during 5 months. Colony type frequencies were observed by plate counting on days 0, 1, 3, 7, 10, 14, 21, 35, 50, 62, 93, and 149 after start of the experiment. Starvation diversifies the population, as Rough (R) and Soft (S) morphotypes emerge among the ancestral Rhizoid (Rz) colony morphotype.
