文摘

We extend the palette of possible colonies models of two different clones of Serratia rubidaea. Our model fits the real morphology of the colonies. We also present that the colony growth leads to a change in the ratio of the fitness which propose to be caused by the production of some signal. This signal influences the behavior of the clones and leads to the prolonged diversity maintenance. The explanation of the diversity maintenance of the mixed concurrent population in one niche is the current studied problem in the ecology and evolution.
