This study compared and analyzed EPT ratio, EPT richness and EPT number(number of species and individuals) of a total of 9 selected sites individually using EPT-group of aquatic insects in Musim stream, also compared similarity ratio between the sampling sites using UPGMA(Unweighted Paired Group Method using Arithmetic average) based on analysis subsequent to species structure of aquatic insects, and compared and analyzed a functional feeding groups(FFGs) of aquatic insects based on stream order. As a result, the aquatic insect group of 2,269 individuals is classified as 71 species, 36 families, and 8 orders, and EPT ratio and EPT richness at sites 3(0.72 and 3.89, respectively) were found to be relatively higher than those at the other sites; by contrast, those at site 9(0.03 and 0.09, respectively) were relatively low. EPT number of species and individuals was found to be lowest at site 9. As a result of UPGMA analysis, the sampling sites in Musim stream were divided into three groups, including A1(site 1, 7, 8), A2(site 2, 3, 4, 5, 6) and B(site 9). According to the results of FFGs, there was not shown specific difference in the number of functional feeding groups by each sites; however, there appeared a little more shredders and scrappers in the upper and mid stream comparing to other sampling sites while collector-filterers and collector-gatherers were found to be dominant in number in the lower stream. According to this research result, the sampling sites in Musim stream were found to have an effect on not only EPT richness, EPT ratio, and EPT number but also FFGs structure. |
