摘要
了解同域分布的野生动物近缘种如何共存是群落生态学研究的重要内容。本研究基于红外相机监测数据并采用核密度估计和占域模型对贵州习水国家级自然保护区内4种主要有蹄类中华鬣羚(Capricornis milneedwardsii)、毛冠鹿(Elaphodus cephalophus)、小麂(Muntiacus reevesi)和野猪(Sus scrofa)的时空共存格局进行了分析。结果发现,4种有蹄类动物活动时间总体分化不大,具有较高的时间重叠,其中中华鬣羚和毛冠鹿的重叠程度最高(△=0.88);在空间上,各物种间都表现为重叠关系而回避关系不明显,不过对栖息地的选择差异,避免了生存资源的强烈竞争。本研究初步揭示了有蹄类在习水保护区同域共存的模式,可为后续生态研究与保护管理提供有益参考。
Understanding how closely related species of wildlife coexist in the same range is an important part of community ecology research.Based on camera trapping monitoring data,we used kernel density estimation and occupancy models to analyze the spatial and temporal coexistence patterns of four ungulates(Capricornis milneedwardsii,Elaphodus cephalophus,Muntiacus reevesi and Sus scrofa)in the Xishui National Nature Reserve,Guizhou.The results showed that four ungulates showed little overall temporal differentiation in activity timing,and had a high overlap index,with the highest overlap(△=0.88)for C.milneedwardsii and E.cephalophus.Spatially,all species showed overlapping relationships and less obvious avoidance relationships,but the differences in habitat selection avoided strong competition for survival resources.This study initially revealed the pattern of coexistence of ungulates in the Xishui Nature Reserve,which can provide useful reference for subsequent ecological research and conservation management.
