高原鼢鼠求偶期巢域变化与体重的研究

The change of home range of plateau zokor during courtship period and its relationship with body mass

研究高原鼢鼠(Myospalax bailiye)求偶期巢域变化对于了解其社群关系、种群动态、繁殖策略等有重要作用。利用无线电跟踪技术监测高原鼢鼠求偶期巢域变化,并分析求偶期高原鼢鼠巢域面积变化与体重的关系。结果表明:1)高原鼢鼠雌雄个体在求偶后期的巢域面积均增加,并且雄性个体巢域面积显著大于雌性(P<0.05);2)求偶后期高原鼢鼠雌雄和雄雄巢域间均发生重叠;3)求偶期高原鼢鼠的巢域面积与体重呈正相关(P<0.05)。

Studying on the changes of home range of plateau zokor(Myospalax baileyi)in courtship stage is vital to understand its social relationship,population dynamics and breeding strategies.The study used the radio tracking to monitor the home range changes of plateau zokor during breeding period in Cairima Township,Maqu County,Gansu Province from March to April in 2019,and the relationship between the change of home range and body weight was analyzed.The results showed that:1)The home range of male and female plateau zokor increased in the late courtship period,and the home range of male plateau zokor was significantly larger than that of the female(P<0.05);2)There was overlap in home range between different sex individuals and between male and male individuals in the late courtship period.3)Correlation analysis showed that the home range of plateau zokor in the courtship period was positively correlated with body mass(P<0.05).
