The data collected by Hartley and her colleagues may be only part of the answer to the question of why some foxes fail to breed even when food is abundant. In other words, breeding performance was not affected by how well-fed these vixens were — something else was at play.

Assuming this is representative of the wild, subordinate matings within a social group presumably occur away from the group, where the dog is perhaps less able to assess social rank. Body condition, and hence resource availability, is a ificant predictor of breeding likelihood in vixens.

Hartley and her co-workers kept 11 orphaned vixens and seven males in family groups Nude mother daughter incest. In populations with a high turnover i. The stress caused by aggression within the social group, specifically that directed to subordinate females by the dominant vixen, can suppress breeding activity.
