因其处于高原生态食物链的顶端,雪豹亦被人们称为“高海拔生态系统健康与否的气压计”而由于非法捕猎等多种人为因素,雪豹的数量正急剧减少。

Abstract:

  The snow leopard is a keystone species in mountain ecosystems of Central Asia and the Tibetan Plateau. However, little is known about the interactions between snow leopards and sympatric carnivores. Using infrared cameras, we found a rocky junction of two valleys in Sanjiangyuan area on the Tibetan Plateau where many mammals in this area passed and frequently marked and sniffed the site at the junction. We suggest that this site serves as a sign post to many species in this area, especially snow leopards and other carnivores. The marked signs may also alert the animals passing by to temporally segregate their activities to avoid potential conflicts. We used the Schoener index to measure the degree of temporal segregation among the species captured by infrared camera traps at this site. Our research reveals the probable ways of both intra- and interspecies communication and demonstrates that the degree of temporal segregation may correlate with the degree of potential interspecies competition. This is an important message to help understand the structure of animal communities. Discovery of the sign post clarifies the importance of identifying key habitats and sites of both snow leopards and other species for more effective conservation.

  青藏高原上雪豹及其它物种的共同标记点

摘要:

  雪豹作为旗舰种,在中亚和青藏高原山地生态系统中起着重要的作用。然而,人们对于雪豹和同域分布的其他动物之间的关系了解很少。我们在青藏高原地区一个山谷交汇点放置红外相机,拍到了雪豹和其他动物经过此地的很多照片。对照片的分析表明,许多动物经过该点时都有嗅闻和标记行为,我们推测这个点被动物们用来发布以及获取信息,起到了类似“公告牌”的作用。另外,我们发现不同物种的动物,为避免冲突,经过这个点的时间不同程度错开,我们利用Schoener指数定量衡量了这种时间上相互错开的程度。这个点上的研究在一个更细的尺度上展示了同域分布的动物在种内和种间的交流。这将有助于我们理解整个生态系统的结构,并为我们保护雪豹的关键栖息地以及整个生态系统提供了重要参考。
