高原鼢鼠种群生态学研究

Study on the Population Ecology of the Plateau Zokor

应用标志流放法对高原鼢鼠种群进行的三年研究表明,其种群数量年内呈增长趋势,年间呈非周期性波动;不同季节雌、雄行为特点差异较大;迁移扩散多数发生在每年10月以后;交配期主要是雄体挖掘寻找配偶;雄体迁入、迁出比率较大。

This work on the Plateau Zokor, MyosPalax baileyi, was carried out in Haibei Research Station of Alpine Meadow Ecosystem from 1987 to 1989. The main results obtained with Mark-recapture ,method were approached.1.The population increased in a year. In different years, the population has changed no-cycle wave.2.In each season, the males and females have different behavior patterns. From October to may of next year, males are espcially important behavioral action. Immigrant and emigrant mainly occured in males.3.In May, the home range of maids is larger than that of females. In October the home range of males is as good as that of females.According to these results, we are sure that the Mark-recapture method can be used to study on ecology and supervise of the population dynamics of the Plateau Zokor.
