| 中文摘要: |
| 青藏高原的草地生态系统被野生动物和家畜广泛地所利用。 大型有蹄类动物和小型哺乳类对其它物种改变而提供栖息地。 基于牦牛放牧的实践,我们发现了高原鼠兔立地占据率跟栖息地变量之间存在一定的格局关系,包括高原鼠兔的建群和区域灭绝率。 为着回答这些变量之间的关系,在软件PRESENCE里,我们采用了多季节性立地占据模型进行对相关数据的分析。 结果表明 ：高原鼠兔局部灭绝率跟植被覆盖度之间存在正相关,但与建群率之间显示负相关。 |
| 英文摘要: |
| The steppes of the Qinghai-Tibetan Plateau are widely used by both livestock and wildlife. Both the grazing of large ungulates and the burrowing of small mammals modulate habitats used by other species. We explored the relationship between site occupancy by plateau pikas and habitat variables based on yak grazing,including the extinction and colonization rate of pikas. To accomplish this, the multi-season occupancy model was used with the program PRESENCE. There was a positive relation between vegetation cover and pika extinction rate, but a negative relation between vegetation cover and pika colonization. |
