Abstract

Community structure refers to the number of species in a community and the pattern of distribution of individuals among those species. The purpose of this paper was to describe a statistical analysis for detecting a ecological biodiversity which is valid even though the assumption at the different sampling points is not violated spatial randomness of species. Counts and cover were determined from 10 ($20\;m{\times}20\;m$) plots in five sites of the Oncheon River which is located in Busan, Korea. Total 95 taxa (85 species, 9 varieties, and one form) were identified and measured in edge sides of this river. These were a total of present in the five sites. Overall across the fragments, mean number of species per plot differed significantly among the five sites (F=7.75, p<0.01). Shannon-Wiener functions differed significantly among plots (F=4.12, p<0.05), with the St. 1 having significantly higher value (2.380) than the others (2.206 for St. 2, 2.116 for St. 3, 2.069 for St. 4, and 0.637 for St. 5). The richness indices, R1 decreased from the upper stream of the Oncheon River to the lower stream. We used a novel way of representing community structure to show that abundance within closely related pairs of co-occurring species in the Oncheon River. The differences between the distributions for of congeners and pairs of non-congeners showed at the largest difference of the cumulative fractions of the data sets (x=0.85).

군집구조란 군집에서 종 수와 이들 종 간 개체들의 분포 양상을 말한다. 본 연구는 다른 지점에서 생태학적 생물종다양성의 통계학적 방법으로 종이 임의로 분포하는지 평가하였다. 이를 위해 부산광역시 도심을 관류하는 온천천의 상, 중, 하류의 다섯 개의 지점을 선정하여 각 지점당 양쪽에 위치한 10개 정점에서 종수를 파악하였다. 95분류군(85종, 9변종, 1품종)이 온천천변에 분포하였다. 다섯 지점에 대해 종수는 유의하게 차이를 나타내었다(F=7.75, P<0.01). Shannon-Wiener의 정보지수는 정점간 유의한 차이를 나타내었으며(F=4.12, p<0.05), 지점 St.1이 다른 지점(St. 2는 2.206, St. 3는2.116, St. 4는 2.069, St. 5는 0.637)에 비해 가장 높았다(2.380). 풍부도 지수에서 R1값은 온천천의 상류에서 하류로 갈수록 낮았다. 공존하는 근연속내 식물종의 풍부도를 근연관계가 먼 그룹과 낮은 그룹 간 분석하는 새로운 군집구조 분석법을 시도하였다. 근연속과 그렇지 않은 속의 쌍 분포도에서 정점 간 유의한 차이를 역시 나타내었다. 축적값은 x=0.85일 때 가장 유의한 차이를 나타내었다.
