Territory size and location in animals with refuges: influence of predation risk
- 55 Downloads
Territory size is usually explained by balancing the benefits of increased size against the costs of defense. An alternative hypothesis for animals that maintain refuges is that the costs of large territories lie in the predation risk associated with leaving the refuge. An optimum territory size is discovered, given only this cost and no cost of defense. Predation risk is also considered a determinant of the value of a territory's location within a colony. Risk relative to location is discovered to be a binary variable, either low or high, depending upon the speed of the predator.
