Figure 1
Intensity of predation modulates interaction of learning and genetic drift. Temporal dynamics of the number of alleles present in populations of prey subject to predation. Panels (a) and (b) show 20 simulation runs for both learning and non-learning scenarios. Panels (c) shows age distributions for panel (a) and panel (d) show age distribution for panels (b). The values in the heatmap are averages from 10 simulation runs. All prey populations consist of 1000 individuals at the beginning of each time step. Individuals killed by predators are replaced at the end of each step through reproduction of surviving individuals ("Methods"). Predators kill the same number of individuals in both learning and non-learning scenarios to allow for a fair comparison. The upper bound on the probability of avoiding or escaping a predator attack is set to 99%. The learning occurs in a default setting, i.e., at the end of every timestep.
