Figure 1

Analytical predictions on the effect of population structure on CI-dynamics. The figure shows the threshold cost-to-benefit ratio (C/B) for the invasion of CI-symbionts. A. Threshold ratio as a function of host migration rate for deme sizes of N = 4 (solid line), N = 20 (dashed line), and N = 50 (dotted line). B. Threshold ratio as a function of deme size for host migration rates of m = 0.05 (solid line), m = 0.1 (dashed line), and m = 0.2 (dotted line).
