Figure 3

Blackmailing leads to cyclic oscillations in the mixed strategies in the presence (A and B) and absence (C and D) of mate guarding. (A) In the presence of mate guarding, all three traits, i.e. monogamy, mate guarding and policing show stable oscillations which form limit cycle (B) in p-q-r space. (C) In the absence of mate guarding monogamy and policing still oscillate in stable oscillations, which form a limit cycle (D) in p-r space. All parameter values are as per Figure 2 except in (C) and (D) y = 0.2, s = 0. Arrows indicate direction of change.
