Biological Diversity of Kingdom Animalia at the Hakri River, Hapcheon-gun, Korea

Man Kyu Huh

This study was conducted the ecological biodiversity of animals and analysis of environmental factors at the Hakri River in Korea during 2015 season. The fauna of four surveyed stations was a total of 69 taxa, representing five classes. Birds (Aves) exhibited the greatest species diversity with 20 taxa identified, followed by invertebrates (15 taxa); mammals with 12 taxa, reptiles/amphibians (Sauropsida/Amphibia) with 11 taxa, and fish represented by 11 taxa. Shannon-Weaver indices (H´) for mammals and birds at upper region were higher than those of low region. Richness indices for animal taxa were also varied among the stations and seasons. Although evenness indices for five animal kingdoms during seasons were different from each other, there were not shown significant differences (p < 0.05). Berger-Parker’s index (BPI) for mammals was varied from 0.121 (invertebrates at Station A) to 0.304 (reptile /amphibian at Station A). The Bray-Curtis’ distances were calculated from differences in abundance of each species according to geographic distances among four stations at the Hakri River. The relationship between a distance matrix and a quantitative environmental variable was shown very strong. The dendrogram showed two distinct groups; Station A and Station B clade and the other stations (Station C and Station D).
