被动式电子标签在监测高原鼢鼠种群生态变化中的应用

Application of PIT marker in research on population and bodyweight of subterranean rodents

地下啮齿动物种群生态学研究经常需要对动物个体进行标记,而传统的剪耳、剪趾标记法会造成动物伤害、影响动物行为等,与动物福利相悖。利用PIT标签于2014年秋季在祁连山东段标记高原鼢鼠30只,研究高原鼢鼠种群密度及越冬后体重、体长和尾长变化。结果表明,样地内高原鼢鼠估算种群密度为44只/hm2;越冬后高原鼢鼠平均体重为222.07g,显著高于越冬前平均体重193.74g,平均体长为19.4cm,显著高于越冬前平均体长18cm;雌性与雄性的体重增长率无显著性差异(P>0.05)。被动式电子标签同时可适用于地下啮齿动物的种群生态学研究,是地下啮齿动物种群生态学研究中的一项新型技术手段。

Subterranean rodents usually need to be marked in research on population ecology,but the traditional marking methods have some disadvantages（it influences the animal behavior and is against with animal welfare）.A passive integrated transponder（PIT）was used to mark 30 plateau zokors in 2014 which were used to study the population density,and variation of weight,height,tail length.The results showed that the population density was 44individuals/ha,the weight of plateau zokor（222.07g）in 2015 was greater than that in 2014（193.74g）significantly,the variation of height was same with weight.The weight increasing rates of males and females had no difference.Therefore,the passive integrated transponder is suitable for the research on population ecology of subterranean rodents.
