Local 'rock-paper-scissors' interaction conserves biodiversity

This animation shows the preservation of biodiversity when the three strains interact locally using the rock-paper-scissors dynamic. The colicin-sensitive strain (blue) is quickly supplanted by the colicin-producing strain (red), which in turn is supplanted by the faster-growing colicin-resistant strain (yellow). The result is conservation of biodiversity.
