Community analysis based on functional feeding groups of aquatic insects in Wonju stream was assessed with the composition of aquatic insects collected for four times at the area from May to November, 2004. The total 92 species of aquatic insects in 62 genera, 37 families, and 8 orders were collected during the period of the investigation. The distribution of the numbers and movements of aquatic insects proved the Woniu stream to be healthy except for St. 7 and St. 9. In the main streams, the occupancy ratio of shredders and scrapers of the functional feeding groups(FFGs) gradually decreased from St. 1 to St. 9 while collectors-gathering and collectors-filtering remarkably increased. In St. 2, the shredders and scrapers posted a higher ratio compared to those in tributaries, and it had the quality of mountain streams. With the results of analysis on the similarity matrix(UPGMA) between each sites of Wonju stream, St. 1, 2, St. 3-8 and St. 9 were classified as the upper stream, the middle stream, and the lower stream area, respectively. |
