高原鼠兔(Ochotona curzoniae)的生态功能

open access: yes野生动物学报, 2013
高原鼠兔作为青藏高原上广泛分布的小型穴居植食性哺乳动物受到了人们的广泛关注。其植食性特点和挖掘活动对高寒草地植被、生物多样性、物质循环等方面具有重要影响,但这种影响对青藏高原草地生态系统的利弊还存在较大争议。一方面认为,高原鼠兔可提高栖息地植被的丰度;维持生态系统的多样性,为捕食者提供食物资源,也为许多其他动物提供栖息地;同时,其挖掘活动会对土壤产生扰动,增加土壤的渗透力和含水量,促进物质循环。另一方面,有学者认为,高原鼠兔会破坏植物根系和土壤结构,加快土壤的侵蚀速度,降低栖息地的植被质量 ...
