We provide an example of each case, though the effects of human activities are likely to be wide-reaching. The core of a territory is generally more valuable to residents than border regions ;and increased aggression when encountering intruders in the core has been demonstrated in various solitary species ;. Third, anthropogenic-induced changes in the environment could influence territorial behavior, both in terms of the relative threat presented by different intruders and the ability to discriminate between neighbors and strangers.

The dear enemy effect arises when territorial animals respond more intensely to unfamiliar strangers than to familiar neighbours. How neighbor—stranger identity influences CAPs remains to be explored.
