| 中文摘要: |
| 柯氏鼠兔(Ochotona koslowi)是兔形目(Lagomorpha)鼠兔属中最古老的遗留种,也是稀有的濒危物种,自1894年命名以来,国内外对该物种的生存现状、生物学特征知之甚少。2007年10～11月,在藏北地区捕获到13只柯氏鼠兔,通过显微组织分析法对其胃及结肠内容物和收集的60份粪样进行了食性分析。结果表明,柯氏鼠兔胃、结肠内容物和粪便中镜检到可识别植物碎片属6科15种,其中豆科植物碎片占可识别植物碎片的39.44%,藜科植物碎片占36.00%,莎草科植物碎片占16.42%,禾本科、十字花科和菊科植物碎片分别占3.75%、2.67%和1.25%。食性分析表明,柯氏鼠兔偏爱豆科植物。 |
| 英文摘要: |
| Kozlov's Pika, Ochotona koslowi is a rare endangered and the most ancestral lagomorph species in Ochotona genus. Little is known about the survival status as well as the biological characteristics of this species since it was named in 1894. In this study,we studied its feeding habits by analyzing the contents of gastric and colon collected from 13 individuals and 60 feces samples from the trapping regions in Northern Tibet during October and November,2007.A total of 15 plant species were identified,belonging to 6 distinct families including Leguminosae,Chenopodiaceae,Cyperaceae, Gramineae, Cruciferae and Compositae that constituted 39.44%, 36.00%, 16.42%, 3.75%, 2.67% and 1.25% of all recognizable plant tissue debris,respectively.Leguminous plants were preferred by Kozlov's Pika. |
