nd yearlings than their fathers. They also showed a stronger physical response towards scent from older sons. The authors contend that this is because the older sons, who are sexually mature, would be more likely to get involved in a physical confrontation to obtain a territory. Yearlings are sexually immature, are usually still living in their family unit and would also be too small to constitute a real threat. Other territory owners are not seen as potential opponents, as they are already well established in their own dwellings.

The authors conclude that "resident territorial beavers showed the strongest territorial response towards older subordinate sons, suggesting that they are considered a bigger territorial threat. These results indicate that territory owners can be identified by scent."
