| 摘 要： | 2004年7—10月,在青海省果洛州玛沁县境内的大武镇东南方向25 km处的格多牧委会草场,采用 样带法和样方法对高原鼠兔(Ochotona curzoniae)贮草行为过程中刈割植物的种类和放置方式进行初步研究。 结果表明:高原鼠兔在植物的生长旺盛期具有为冬季贮藏干草堆的行为,贮草行为始于7月,结束于10月初。 高原鼠兔对所刈割植物种类的选择,在一定程度上受栖息地植被物种丰富度的影响,并且将刈割植物放置于具 有宽大叶片的植物上,以防止干草的腐烂。挖洞结果显示,高原鼠兔具有洞内贮藏食物的习性。

| Abstract: | We studied caching behavior in the plateau pika Ochotona curzoniae in the Dawu, Guo Luo, Qinghai Province from July to October of 2004 when caching behaviour occurs. Counts of cradaled plant species were obtained using placement, quadrat sampling, and transection methods. The results showed that in the growing season plateau pika cached hay-piles for feeding in the winter. Plant species chosen by the plateau pika reflected their habitat vegetation. Plants collected by plateau pika were placed on plants with spacious leaves to prevent the hay-piles from rotting. The results of excavation indicated that plateau pika habitually store food in holes. |
