摘要

摘要冬眠(denning)是亚洲黑熊(Ursus thibetanus)生活史的一个重要方面，而denning的年表可能受到生物和非生物因素的影响。我们利用统计过程控制与活动传感器相结合的方法，研究了亚洲黑熊在成洞前的活动模式，定量地确定了2006年至2017年日本雅修-日光山脉的活动显著减少。35例中有29例(83%)检测到成窝前活动，平均持续时间为2.7±1.7天，比棕熊(U. arctos)短1 ~ 3天。熊的年龄、性别和硬杆的丰度对预成窝持续时间的影响不显著。

Factors Affecting Pre-Denning Activity in Asian Black Bears

Abstract. Hibernation (denning) is an important aspect of the life history of Asian black bears (Ursus thibetanus), and denning chronology can be influenced by biotic and abiotic factors. We investigated activity patterns during the pre-denning period of Asian black bears using statistical process control in combination with activity sensors to quantitatively identify a marked reduction in activity from 2006 to 2017 in the Ashio–Nikko Mountains, Japan. Pre-denning activities were detected in 29 of 35 cases (83%), with an average duration of 2.7 ± 1.7 days, which is one to three days shorter than the duration for brown bears (U. arctos). The effect of bear's age, sex, and the abundance of hard mast on the duration of pre-denning were not significant.
