Plateau pikas (Ochotona curzoniae) often clip tall plants near active burrow entrances to detect and avoid predators. This clipping behavior influencing plant communities near active burrow entrances has not been well documented. A field experiment was conducted to investigate the effects of this clipping behavior on plant communities across three sites in the Qinghai-Tibetan Plateau by comparing plant communities near active burrow entrances with communities near abandoned burrow entrances. This study showed that the clipping behavior decreased plant community height and increased plant cover and species richness of the community and had no effect on plant community biomass across three sites or at each site. This study further showed that clipping behavior decreased the plant biomass of the graminoid group and had no effect on the plant species richness of the graminoid group, whereas it increased the plant biomass and plant species richness of the forb group across the three sites or at each site. These findings suggest that a general pattern concerning the effect of the clipping behavior can increase plant species richness and decrease the grazing quality of alpine meadows near active burrow entrances.

高原皮卡斯的剪裁及其对植物群落的影响

高原鼠兔(Ochotona curzoniae)通常会在活跃的洞穴入口附近修剪高大的植物,以发现并避免掠食者。这种剪切现象影响活跃的洞穴入口附近的植物群落,目前还没有很好的记录。通过比较活跃的洞穴入口附近的植物群落和废弃的洞穴入口附近的群落,进行了田间试验,以研究这种剪枝行为对青藏高原三个地点的植物群落的影响。这项研究表明,修剪行为降低了植物群落的高度,增加了植物群落的覆盖度和物种丰富度,并且对三个地点或每个地点的植物群落生物量没有影响。这项研究进一步表明,修剪行为降低了类动物类植物的生物量,对类动物类植物的物种丰富度没有影响,而它增加了三个地点或每个地点的forb群的植物生物量和植物物种丰富度。这些发现表明,有关修剪行为影响的一般模式可以增加植物物种的丰富性,并降低活跃洞穴入口附近的高寒草甸的放牧质量。
