Which of the following is not a reason that populations display a regular (evenly spaced) distribution?

Regular, evenly spaced distributions often result when individuals keep others away from a territory or compete for limited resources such as water or sunlight. Social behavior more commonly draws individuals together into groups, producing a clumped distribution rather than an evenly spaced one. Therefore, social behavior is not a reason for regular distribution.
