摘要
1984—1987年在青海湖黑马河湖滨地区,以耳标观察法对高原鼠兔繁殖期交配关系的研究表明:高原鼠兔种群中单婚制占39.73％;一夫多妻(2—5)占45.21％;二夫一妻和多妻(2—4)占15.07％,其中2只雄鼠必有1只为主雄,另1只为次雄。
Adult sexual behavior and mating system in a marked population of plateau pika (Ochotona curzoniae), using marked ear-tag methods, were studied for a 4-year period, 1981-1987 in Heimahe of Qinghai Lake.
One male associated with one female (monogamy) is 39.73% of the population of plateau pika in the breeding season,and with two females or more than two (polygamy) is 45.21% at the same home range or in different home ranges. Another phenomenon is that sometimes there were more than one male, but among them one must be the dom-inant,which is 15,07% of the mating system of the breeding population.
