Dominant and subordinate outside options alter help and eviction in a pay-to-stay negotiation model

Abstract

Subordinates “pay rent†to stay in their group, but pay less when they can move elsewhere. For many animals, group living comes with costs: smaller individuals get evicted unless they help on the territory. Using theoretical models, we show that negotiation is key to enforcing pay-to-stay cooperation: subordinates provide fitness benefits to dominants and negotiate help based on breeding opportunities outside the group, but only when subordinates can plastically increase help in response to demanding dominants.
