Comparison Habitat Preference for Small Mammals around the Hyeongsan River
이정일 (동국대학교)
Abstract
This study was conducted to clarify the preference and habitat condition of small mammals at the Hyeongsan river in Ulsan, Gyeongju, and Pohang from January 2003 to July 2003. In the study sites, total 111 individuals of Apodemus agrarius, Rattus norvegicus, and Micromys minutus were captured in study sites. The most abundant species were Apodemus agrarius, 79.2 percent, among the captured small mammals. Density of habitation was significantly higher in agricultural land than in either private house or woods. However, they were more abundant in paddy field area than in agricultural land. A number of captured small mammals were higher in herbaceous rather than three other vegetation types. Existent of river embankment and its type were important factors affecting the spatial distribution of the individuals. Preference of small mammals were significantly lower in revetment block area rather than in none or nature-stone mat area. There was significantly correlationship between the depth of water and the number of captured small mammals. A number of captured small mammals were clearly increased in reference to decreasing depth of water in study site. In conclusion, the following factors such as the vegetation structure, depth of water, types of land use and types of river dike could be affected the spatial distribution of small mammals in the study sites.
