摘　　要：Stray dog invasion caused by human activities poses a significant challenge to wildlife communities worldwide.Conservation biology efforts must prioritize controlling stray dog populations to maintain equilibrium within local wildlife communities.In the Helan Mountains,ungulate population recovery and the absence of top predators present critical issues.The presence of a stray dog as a predator may complicate ecological restoration efforts in the region.Through molecular and camera trapping data analyses,we investigated the overlap of eco-logical niches between stray dogs and local carnivores across nutritional and spatiotemporal dimensions.The re-sults revealed a high overlap between stray dogs and local carnivores across various niches,likely linked to food abundance,suggesting the possibility of increased future competition between them.Stray dogs cannot be ignored when conservation of wild carnivores involved.流浪狗入侵是全球各地野生动物群落面临的重大挑战之一,这主要是由于人类活动所导致的。为了保护当地野生动植物群落的平衡,保护生物学工作必须着重控制流浪狗数量。在贺兰山地区,有蹄类动物的数量正在恢复,而顶级捕食者的缺失是关键问题。流浪狗的存在可能会给该地区的生态恢复工作带来复杂的问题。通过对分子和红外相机数据的分析,我们研究了流浪狗和当地食肉动物在食性、时间和空间方面生态位的重叠情况。结果显示,流浪狗与当地食肉动物在各个生态位存在高度重叠,这可能与食物丰富度有关,暗示它们之间未来可能会增加竞争。在涉及保护野生食肉动物时,我们必须重视流浪狗的存在问题。
