Seasonal home range shift and dispersal of red deer at Saihanwula Biosphere Reserve,China
Red deer seasonal home range size and young buck dispersal was studied using radio-tracking data for three deer from 2007 to 2009 at Saihanwula Biosphere Reserve,Inner Mongolia.The annual and seasonal home ranges,the overlap of the Kernel home range were analyzed.The results showed that home range sizes of red deer had seasonal differences with the area of home range(95%fixed Kernel estimation)changed obviously with seasons,with the largest size of 624 ha in spring(20 telemetry locations),followed by 370 ha in winter(30 telemetry locations),325 ha in autumn(22 telemetry locations),the smallest range of 233 ha in summer(22 telemetry locations).Home ranges overlapped between female deer,particularly in autumn and winter.The core home range did not change seasonally, implying stable habitat selection.The area of the 75%fixed Kernel estimation was 107 ha in autumn, 104 ha in winter,103 ha in spring,and 67 ha in summer,respectively.During dispersal period young buck tried several time to find new habitat.Our results indicated that there was no specific avoiding behavior to reduce predation risk in red deer habitat selection and isolated nature reserve limited stag deer dispersal which may decrease population genetic diversity.
