抄録: | Behavioral freedom is becoming an increasingly important issue bridging animal welfare and conservation biology. This study focused on range size and spatiotemporal variation in Western chimpanzees, creating a novel index for behavioral freedom. Direct observations were conducted on a group of seven free-ranging chimpanzees in Bossou, Guinea, during 10-hr observation periods over 10 days, and on a group of five captive individuals at the Kumamoto Sanctuary during 7-hr observation periods over 7 days. Bossou chimpanzees showed dynamic ranging patterns; their range size was larger, and their day and time-of-day ranges did not generally overlap. Additionally, the average time-of-day range was 5.2 times greater than the day range. In contrast, sanctuary chimpanzees showed a static ranging pattern, with a smaller range size and a time-of-day range to day range ratio of 1.0. Therefore, the time-of-day range to day range ratio is a suitable quantitative index of behavioral freedom in chimpanzees. |
