Kwon, Oh-kyun,Toda, Masanori J 제주대학교 1981 논문집 Vol.13 No.-
1979年 8月 12日과 13日에 大韓民國 濟州島에서 초파리相의 豫備調査를 한 結果 短期間이기는 하나 濟州島産 초파리 59種이 採集된 中 末記錄種 17種이 採集되었기로 그 List를 報告하는 바이다. 1. 濟州島의 초파리相은 固有率은 낮으나 韓國 및 日本과 극히 가까운 關係가가 있음을 나타내었다. 2. 調査를 한 廣葉樹林의 초파리 群集은 基本的으로 林冠에서 果實을 먹는 集團과 林床에서 버섯類를 먹는 集團에 依하여 構成되어 있다. 3. auraria-complex 中 D. triauraria은 濟州島, 對馬島 및 隣近의 諸島에서 特히 높은 相對瀕度를 나타내었으나 韓國의 山岳地帶에서는 減少는 傾向을 나타났다. 4. 樹幹部에서 採集된 것은 subgenus Hirtodrosophila 特히 hirticornis group 및 subfamily Steganinae 에 依하여 特徵지여지는 獨特한 種構成을 나타내었다. A total of 59 drosophilid species were reported from the Quelpart Is., including 17 secies new to the Island. The drosophilid fauna of the Island is not much endemic, closely related both to those of the Korean and Japan. The community of a secondary broad-leaved forest is essentially composed of two guilds, Canopy-Fruit Feeder Guild and Floor-Fungus Feeder Guild. D. triauraria occupies a high percentage of the auraria complex not only in the Quelpart Is. but also in some adjacent islands such as the Tsushima, but decreases in proportion toward northern mountainous regions of the Korean Peninsula. Collections on tree trunks brought particularsamples characterized by subgenus Hirtodrosophila, especially hirticornis group, and steganine genera. The lacation of the Quelpart Is. is important to consider the faunistic relationship between Japan and the East Asian Continent. Up to the present, several collection records of drosophilid flies from the Island have been reported by Korean researchers(Chung 1955, 1958, Paik &Kim 1957, Kang, Chung & Lee 1959, Lee 1964). However, no studies have been done on its drosophilid community from the standpoint of geographical ecolgy, which has been recently advancd by MacArthur and his co-werkers (cf. MacArthur 1972) and is a fruitful field to study the evolution of community structure. We had an opportunity to make a brief ecological survey on drosophilid community in the Island, and report here some preliminary information on faunistics and ecological structure of the community. Before going further, we wish to express our sincere thanks to Prof. Sh. F. Sakagami, the Institute of Low Temperature Science, Hokkaido University, for his reading of the manuscript, and also to president Dr. S. M. Pyun and Prof. C. C. Choung of Cheju National University, and Nagasaki Biological Society in supporting our survey in the Island.
