Spatial-temporalniche characteristics of three ungulates in the forest area of Huangnihe
In order to explore the homogeneous coexistence mechanism of three ungulates (Cervus elaphus),roe deer (Capreolus pygargus)and wild boar (Sus scrofa),the daily activity rhythm and spatial distribution of the three ungulates were studied in Huangnihe forest region by infrared camera method and large sample method.The daily activity rhythms of the three ungulates have a high degree of overlap,but the activity peaks are staggered with each other.Red deer and roe deer are morning and evening animals,and wild boar are diurnal animals;In the Huangnihe forest area,the three habitats have a large overlap area.The geographical distribution overlap of red deer and roe deer is 0.648 and 0.865 respectively,the geographical distribution overlap of red deer and wild boar is 0.601 and 0.809 respectively,and the geographical distribution overlap of roe deer and wild boar is 0.701 and 0.912 respectively;The three ungulates achieve spatial niche separation under altitude and human disturbance factors.This study preliminarily analyzed the spatiotemporal nichecharacteristics of three ungulates,providing reference for the protection and management of ungulates in the same region.
