국제적 멸종위기종인 산양 암컷(n=6)의 출산시기 행동권 분석을 위해 2007년 3월부터 2014년 5월까지 설악산국립공 원, 월악산국립공원 2지역에서 GPS collar 발신기를 이용하여 연구 수행하였다. 분석결과 출산시기에 따라 행동권의 변화를 확인하였다. MCP 95%에서 봄 1.00±1.00km2 > 가을 0.66±0.30km2 > 여름 0.61±0.40km2 > 겨울 0.50±0.10km2 (F=4.240, p<0.05)로 분석되었으며, 월별분석은 5, 6, 7월에 급격이 행동권이 작아지는 특징을 보였으며, 통계적으로 유의적인 차이를 보였다(F=24.261, p<0.01). 이렇듯 행동권의 급격한 변화를 보인개체들은 새끼를 출산한 개체로 확인 되었고, 행동권이 급격히 작아지는 것을 확인 할 수 있었다. 평균 이용고도는 615.77±173.508m이며 출산개체와 비출산 개체 모두 큰 차이는 없었다. 이러한 분석을 통하여 출산 시기 등을 고려한 개체관리 및 복원에 적용할 수 있을 것으로 판단된다.
To analyze the behavioral characteristics of Korea endangered species female gorals (n=6) during the period of birth, using GPS collar attached on their necks, we carried out this study in two areas (Seoraksan and Woraksan National park) from March 2007 to May 2014. According to our analysis there was a change in their home range during the period of birth. The home range of females (n=6) in MCP 95% was Spring (1.00±1.00km2) > Autumn (0.66±0.30km2) > Summer (0.61±0.40km2) > Winter (0.50±0.10km2) (F=4.198, p<0.05). In the monthly analysis, their home ranges were dramatically reduced in May, June and July. It showed a statistically significant difference (F=24.261, p<0.01). These gorals showing a drastic change in home ranges were identified as gorals having offspring individual and their home ranges were decreased. The average altitude was 615.77±173.508m and there was no significant difference in major change between parous and nonparous female gorals. Through this analysis, we expect that it can be applied to the goral management and restoration project considering the time of birth.
