摘要
香鼬(Mustelaaltaica)喜栖于人类居住区附近的高寒草甸草场,主要以高原鼠兔(Ochotonacurzoniae)为食,其数量分布与高原鼠兔的密度分布成正相关。在高原鼠兔的繁殖盛期,香鼬主要捕食鼠兔幼体,每只成体平均每天捕获鼠兔6.2只,相当于每100克体重日获取食物重量273.5克,在高原鼠兔的繁殖后期和非繁殖期,每只成体平均每天捕获鼠兔2.75只,相当于每100克体重日获取食物重量296.3克。繁殖期育幼任务全部由雌性成鼬承担,幼鼬从7月初开始地面活动,8月初开始扩散。
This paper deals with the habitat selection,feeding and caring for the young of thealpine weasels.The weasels prefer to the habitats of alpine meadow where human livednearby and feed mainly on plateau pika,their numbers were positively correlated withthe density of pika. From June 20 to July 5,each weasel averagely captured pika 6.2 in-dividuals a day,but 2.75 individuals from July 14 to August 9.The reproductive periodof the weasels was coincided with that of pika. The works of caring for the young werecompleted only by female. The young appeared on the ground at early of July,and dis-persed at early of August.
