浙江遂昌地区同域分布猪獾与花面狸时空生态位比较
Comparative study on the spatial and temporal niche of the same do-main distribution of Arctonyx collaris and Paguma larvata in Suichang,Zhejiang Province
摘要
Abstract
The hog badger(Arctonyx collaris)and the masked palm civet(Paguma larvata)are dominant species among small carnivores in the mountainous areas of Suichang,Zhejiang,with similar feeding habits and environmental niches.In order to explore the mechanism by which hog badger and masked palm civet coexist in the same region,we conducted infrared camera monitoring in five sample areas(Baima Mountain,Qianfo Mountain,Jiulong Mountain,Niutou Moun-tain,and Hushan)of Suichang County,Zhejiang Province from June 2020 to June 2022.71 camera deployment sites were selected and a total of 123 infrared cameras were used,resulting in a total of 19 654 effective working days and 2 184 independent effective events.We build species distribution models and daily activity rhythm models to ana-lyze the spatiotemporal niches of hog badger and masked palm civet in the region.The results showed that both species were dominant among the local intermediate predators,but the relative abundance index(RAI)of hog badgers(9.26)was higher than that of masked palm civets(3.96).Both species exhibited high similarity in habitat selection,with an overlap coefficient of 0.783 and an index of 0.960 in spatial niche.There was a significant difference in diurnal activity between the two species(P＜0.01),with hog badgers being active both during the day and night,while masked palm civets were mainly active at night.There was a significant overlap in spatial niche between hog badgers and masked palm civets,but a considerable differentiation in temporal niche,indicating a tendency for coexistence through reactive strategies between the two species.This study provides preliminary insights into the spatio-temporal niche characteristics and coexistence mechanisms of hog badgers and masked palm civets and serves as an example and theoretical reference for understanding interspecific relationships and biodiversity conservation of coexisting intermediate predators in the same region.关键词
