天津盘山同域分布野生豹猫与貉时空活动规律研究
Comparative study on spatio-temporal activity of sympatric Prionailurus bengalensis and Nyctereutes procyonoides in Panshan Mountains of Tianjin
摘要
Abstract
The coexistence mechanism of sympatric species remains a complex topic and has yet to be fully elucidated.From July 2019 to December 2022,this study applied infrared camera technology to conduct comparative study on the temporal and spatial activities of Prionailurus bengalensis and Nyctereutes procyonoides in Tianjin Panshan Scenic Spot in order to explore the characteristic and potential mechanisms of niche differentiation among sympatric species.We found that the relative abundance index(RAI)of P.bengalensis was overall higher than that of N.procyonoides,and there was no significant seasonal difference on RAIs for each species.In terms of daily activity patterns,both species have two daily activity peaks based on the annual data(P.bengalensis:03:00-05:00,19:00-20:00;N.procyonoides:01:00-03:00,20:00-23:00),although there were some small non-significant differences.In terms of altitudinal activi-ty,the average altitude recorded for P.bengalensis andN.procyonoides was(420.390±15.161)mand(322.415±14.560)m,respectively,but it varied seasonally.The average altitude for P.bengalensis was significantly higher than that in N.procyonoides for each season.Sympatric leopard cats and raccoon dogs formed a degree of temporal and spatial niche dif-ferentiation.This study provides valuable scientific insights for the integrative conservation and management of related species and their natural habitats.关键词
