Dear enemies or nasty neighbors? Causes and consequences of variation in the responses of group-living species to territorial intrusions

Abstract: Responses of territorial groups to intruders depend on rival identity. We explore reasons for variation in responses to neighbors versus strangers arising between species, social and ecological conditions, and group members. We also consider the potential consequences of this variation for group dynamics, collective decisions, and individual benefits and costs. Finally, we suggest theoretical modeling, hormonal mechanisms, and man-made disturbances as avenues of future research that would enhance our understanding of group-territorial behavior and sociality.
