Bio3520 Chapter 14 Aggression
  1. Animals often exhibit             in many contexts, including territory, mating, and foraging.
  2. The decision to fight requires estimating tradeoffs between the       (C) involved in the behavior and the        (V) obtained from the resource.
  3. These payoffs can be examined by game theory models.
    • The hawk-dove game favors a       strategy when V > C.
      • In a variation called the bourgeois -                game, the territory owner and an intruder may experience different C and V values.
    • The      of attrition game tries to model the          of contests.
    • The             assessment model considers an opponent's fighting abilities in decisions about aggressive behavior.
  4. Aggressive behavior often produces winner and        effects among the contestants, sometimes resulting in a dominance hierarchy.
  5. Hormones often play a            factor in animal aggression.
