From: Plastic behaviors in hosts promote the emergence of retaliatory parasites
Game tree of host-parasite interaction in the complex model.
A host lays bh eggs in a clutch which can become parasitized by bp parasitic eggs. Depending on the host's threshold trait t, the host may accept the parasitism (if bp ≤ t) incurring a parasitism cost cp, a nestling cost cn. When hosts reject parasitism (if bp>t), they risk being forced to re-clutch, resulting in costs cr. The parasite gains the accepted egg, bp.
