Abstract
- To examine the species composition and population fluctuation ofbutterflies at Mt. Yudal, Mokpo, we collected butterflies from May, 2001 to April, 2002by dividing the study site into four subregions. As a result, seven families comprising40 species were identified. The patterns of population fluctuations at the foursubregions showed that the lower the elevation the higher the number of species andindividuals. Monthly fluctuations of butterfly species produced an M-shaped curve,whereas those of individuals produced a monotonic curve with a maximum peakduring August. To see effectively the changes of numbers of species and individuals,we calculated the indices of species richness and evenness by subregions and months.As a result, both indices fulfilled the primary criterion of independence and showedmore or less negative association: when heterogeneity is higher, evenness is lower.Examination of butterfly populations over long-term periods might provide anevidence of global warming and a guideline to conserve and manage habitats.
