Geographical distribution characteristics and diurnal activity rhythms of Naemorhedus griseus in Hubei Daliang nature reserve
摘要
Abstract
As a class Ⅱ national protected wild animal and a vulnerable species,Naemorhedus griseus is of high conservation concern.Investigating its geographical distribution and diel activity rhythms can provide data support for the conservation and management of this species in Hubei Daliang nature reserve.From May to July 2025,45 infrared camera traps were deployed in Hubei Daliang nature reserve to monitor the activity of N.griseus.The relative activity intensity index(IRA)was used to analyze its geographical distribution and diel activity rhythms,generalized linear model(GLM)was applied to examine the correlation between elevation and the number of detected N.griseus,and its diet was analyzed based on field survey results.The results showed that N.griseus was commonly found in evergreen and deciduous broad-leaved mixed forests,primarily distributed at elevations of 1 000 to 1 099 m.The GLM result indicated that elevation had a certain influence on the occurrence of N.griseus.The diel activity rhythm of N.griseus exhibited two activity peaks:one after 06:00 and another around 17:00,with low activity intensity at night,classifying it as a typically diurnal species.Field surveys revealed that N.griseus preferentially feeds on young leaves,buds,fruits,and other plant tissues in mid-to high-elevation forests and shrub habitats,and adjusts its food species and foraging elevation with seasonal changes.This study provides a case for understanding the habitat adaptation strategies and rhythm differentiation mechanisms of ungulate species in the north subtropical transition zone,as well as scientific support and practical reference for the construction of regional biodiversity conservation networks,refined management of endangered species,and maintenance of ecosystem integrity.关键词
