한라산 북사면 산림조류의 군집구조에 관한 연구 = A Study on the Community Structure of the Forest Birds of the Northern Slope In Mt, Hania

다국어 초록 (Multilingual Abstract)

An analysis of the regional community structure of the forest birds on Cheju island was carried out over a period of three years, from January, 1980 to December, 1982. Multiple monthly observations were made during this period at various levels in three defferent areas around Mt. Hanla (Gwangryeong. Gwaneum-sa, Eorimog).
The results are as fellows.
1. The total number of species found in Gwangryeong was 42, Gwaneum-sa 26 and in Eorimog 40.
2. 14 common species were distributed all over the areas surveyed. 16 common species were found in Gwangryeong and Gwaneum-sa, 20 in Gwaneum-sa and Eorimog, 24 in Gwangryeong and Eorimog.
3. The three most dominant species distributed all over the survey areas were, in order of importance, Hysipetes amaurotis, Carduelis sinica, and Parus major, but Emberiza cicoides instead of Parus major.
4. The order of seasonal species variation at each area was:
a) Gwangryeong; winter visitors > resident > transients > summer visitors
b) Gwaneum-sa; residents > summer visitors > transients > winter visitors
c) Eorimog; summer visitors > residents > transients > winter visitors
5. An inverse correlation between the species and observed numbers was found highly significant.
6. The dominant degree in Gwangryeong was high in summer while in Gwaneum-sa and Eorimog was low in winter and high in summer.
7. Diversity was high in Gwaneum-sa but low in winter apd high in summer Gwaneum-sa, Eorimog.
8. Evenness was generally irregular in three areas.
9. There was no significant correlation among the different areas in dominancy, diversity, and evenness.
