食物和环境丰容对半散放环尾狐猴日行为活动的影响

open access: yes野生动物学报, 2020
丰容能提高圈养动物福利和行为多样性。2018年10—12月,对深圳野生动物园半散放环尾狐猴(Lemur catta)进行食物丰容与环境丰容,采用焦点取样法和瞬时扫描取样法观察丰容前、食物丰容和环境丰容阶段的环尾狐猴行为,比较分析不同丰容阶段环尾狐猴的日行为时间分配和行为节律变化。结果表明:食物丰容后环尾狐猴的搜寻行为显著增加,环境丰容后玩耍行为显著增多,这两个丰容阶段环尾狐猴的攀爬、行走、社群行为均显著增加,而睡觉、休息和异常行为则显著下降。丰容后环尾狐猴的活动节律也发生了变化 ...
