Survival curves under different scenarios of transposition activities and population sizes. All changes in transposition events occur after 5000 generations (vertical lines). In the left panel, we compare the three settings in transposition rates. The right panel demonstrates the influence of different population sizes. Transposition bursts lead to more IS extinctions (red), and down-regulation of the bursts can lead to IS survival that is at a similar level to no burst scenario (black and blue). Each curve was calculated based on 1000 simulation runs, and each simulation was run for 30,000 generations. The survival probability of ISs for each curve at the end of simulations was given in parentheses. Parameters: No burst (blue): δ=0, γ=0. Burst, no regulation (red): γ=0. Population size N=104 (dark grey) and 106 (light grey). The population is initialised with an IS distribution according to Sawyer et al. [62]. Other parameter values are as given in Table 1
