Long-term changes in the winter home ranges of Japanese monkeys in the Shiga heights
In the home ranges of the monkeys, the densely utilized food sites (densely utilized sites of food resources ofWada andTokida, 1981) varied over a period of ten years. The Shiga B2 troop changed both its densely utilized food sites and the kinds of tree mostly eaten within the same home range, whereas the Shiga C troop transferred to a new home range. The home range transition of the C troop was influenced by both food deficiencies and the existence of the B2 troop. Based on these facts, it can be said that two types of long-term home range utilization were distinguishable.
