Preliminary exploration of the spatial ecological relationships of Carnivo-rous species in Renhuai,Guizhou
摘要
Abstract
Renhuai City is one of the top ten economic counties in western China,with severe human disturbance and a high degree of urbanization.To understand the interspecific ecological spatial relationships of carnivorous species in this area and clarify their survival and distribution within the region,we conducted a series of field surveys and monitoring with infrared cameras in the whole area of Renhuai City from October 2022 to November 2023.We analyzed the spatial ecological relationships of seven medium and small-sized carnivorous species using species distribution modeling and as-sessed their interspecific ecological niche overlap using ENMTools.The results show that the distribution patterns of suitable habitats for the seven carnivorous species in the study area are similar and distributed mainly in the southern and eastern parts of Renhuai City.However,the sizes of suitable habitats differed among the species,with Arctonyx collaris occupying the largest suitable habitat area(1 288.023 km2)and Meles leucurus occupying the smallest area(615.867 km2).We detected significant differences in the selection and response to different environmental factors among the seven species.Temperature annual range is the dominant factor driving the distributions of Prionailurus ben-galensis,Meles leucurus,Paguma larvata,and Viverricula indica.The distributions of Mustela kathiah and Arctonyx col-laris are mainly affected by the normalized difference vegetation index,while the most important factor affecting the dis-tribution of the Melogale moschata is precipitation seasonality.The environmental ecological niches and geographical distributions of the seven carnivorous species overlapped highly in the study area.This study reveals the distribution characteristics of suitable habitats for seven carnivorous species and their spatial relationships in Renhuai City,and pro-vides scientific support for regional biodiversity conservation and management.关键词
