Summary: | The objectives of this paper are to estimate home range and core habitat area of raccoon dog living in the rural area of Korea. A radio-telemetry study was carried out on 22 raccoon dog individuals. Among these individuals, 4 raccoon dogs made 2 pairs and they were monogamous and moved together all the year round. Mean home-range size of 9 individuals which were radio-tracked more than 3 months was $0.80km^2$ (100% MCP). The mean home range size of male individuals was $0.98km^2$ (N=5, 100% MCP) and that of female individuals was $0.58km^2$ (N=4, 100% MCP). On the other hand, in case 95% MCP(Mininlum Convex Polygon) was applied, the gap of home-range size between sex distinction was closed to $0.63km^2$ (male) and $0.42km^2$ (female). The home range size of two pairs of which the male and the female were radio-tracked at the same time showed little difference. In case of one pair, the home range size(95% MCP) was $0.28km^2$ (male) and $0.26km^2$ (female) and in case of the other pair, it was $0.36km^2$ each (male and female). Consequently there seems no significant difference in the home-range size between a male and a female racoon dog except the unusual cases such as unpaired individuals or the ones with no fixed territory. 본 연구의 목적은 농촌지역의 너구리 행동권과 핵심지역의 면적을 분석하는 것으로서, 이를 위해 22개체를 포획하여 원격 무선추적을 실시하였다. 이 중 3개월 이상 무선 추적이 실시된 9개체의 행동권을 분석한 결과 평균 $0.80km^2$ (100% MCP)를 나타내었다. 성별 행동권은 수컷이 평균 $0.98km^2$ (100% MCP)를 나타내었고, 암컷은 평균 $0.58km^2$ (100% MCP)를 나타내어 수컷의 행동권이 넓었다. 그러나 95% MCP (Minimum Convex Polygon)를 적용했을 경우 수컷이 평균 $0.63km^2$, 암컷이 $0.42km^2$로서 차이가 많이 줄었다. 또한 암수 쌍이 함께 무선 추적된 두 쌍의 행동권은 95% MCP를 적용했을 경우 암수가 각각 $0.26km^2$와 $0.28km^2$로서 차이가 매우 적거나, $0.36km^2$와 $0.36km^2$로 통일했으며, 4 계절 모두 짝을 지어 함께 지냈다. 따라서 짝이 없거나 영역이 정해지지 않은 등의 경우를 제외하고 정상적으로 암수가 한 쌍이 되어 지내는 일상의 경우에는 암수의 행동권이 같다고 판단되어진다. 원격 무선 추적된 너구리 중 4 개체는 암수 쌍을 이루고 있었으며, 이들 두 쌍 모두 일부 일처제를 이루고 함께 이동하며 생활하였다. |
