救护前期穿山甲的日常行为表达

Daily Behavioral Expressions of Pre-rescue Pangolins

穿山甲作为习性特化的动物,对外界刺激极其敏感。新救护个体经过长途运输或圈禁,容易因应激反应剧烈导致动物拒食或死亡。为了解救护前期穿山甲的行为特点,进而提高穿山甲的救护存活率,利用目标动物取样法对处于救护前期的中华穿山甲Manis pentadactyla和马来穿山甲M.javanica进行行为的观察记录,共得到11636 min有效观察时间,进一步分析发现:穿山甲休息行为出现的频次和时间占比最高,分别为8.25次/d、66.70%;活动行为中行走出现的频次和时间占比最高,分别为3.81次/d、26.01%;由于环境空间的限制和人为因素的影响,穿山甲行为的多样性降低,嗅探、挖土和站立行为的占比仅为2.45%、1.86%、0.99%。因此,应对环境进行丰荣,模拟野外生活环境,从而增加其行为的多样性,减少刻板行为的发生。

As a habit-specialized animal,pangolins are extremely sensitive to external stimuli.After long distance transportation or confinement,the new rescue individuals are prone to severe stress reaction leading to animal food refusal or death.In order to understand the behavioral characteristics of pre-rescue pangolins and improve their rescue survival rate,the target animal sampling method was used to observe and record the behaviors of Manis pentadactyla and M.javanica in their early rescue period.A total of 11636 effective observation minutes was obtained.Further analysis showed that the frequency and time of rest behavior of pangolins were the highest,which were 8.25 times/d and 66.70%,respectively.The highest frequency and time share of walking among the active behaviors were 3.81 times/d and 26.01%,respectively;Due to the limitation of environmental space and anthropogenic factors,the diversity of pangolin behaviors decreased,with only 2.45%,1.86%and 0.99%of sniffing,digging,and standing behaviors.The environment should be enriched to simulate the environment of living in the wild,thus increasing the diversity of their behavior and reducing the occurrence of stereotypical behavior.
