高原鼠兔的繁殖空间及其护域行为的研究

A STUDY ON THE BREEDING AREA AND THE TERRITORIAL BEHAVIOR IN PLATEAU PIKA (OCHOTONA CURZONIAE)

1985—1987年在青海湖黑马河湖滨地区,以耳标法研究了高原鼠兔(Ochotona curzoniae)的繁殖空间及护域行为。结果表明高原鼠兔营群体家族式生活,具有巢区和领域。繁殖期,雌雄配对建立新的家庭,巢区发生相对变化。并以亲昵、长鸣、嗅味标记和驱逐等行为维护其领地。

Breeding area and territorial behavior in a marked population of plateau pika(Och-otona curzoniae) were studied over a 3 -year breeding period,1985-1987 in Heimahe of Qinghai Lake. Plateau pika is a characteristic steppe dwelling pika. They stay relatively close to their burrow system and live colonially in family groups. The home range is an area over which a family member commonly roams,but does not necessarily defend.Territory is an area less than their home range, frequently used and defended by the parents. During the breeding season female-male,suggesting a system of pairing,establish a new family and a home range. Maintenance of territories is enhanced by affiliative behaviors, long calling, scent-marking, and aggressive behaviors (chasing,fighting), and aggression is greater among males than females.
