UPGMA ANALYSIS OF MICROMYCETE BIODIVERSITY IN MOUNTAINOUS ENVIRONMENTS OF YUNNAN PROVINCE
不加权组平均法在云南山地小型真菌生物多样性研究中的应用

genera of micromycetes were isolated from 48 selected areas, which belong to seven different mountainous ecological environments of Yunnan Province, China. Niche breadths of the micromycetes and their biodiversities in the 48 sites were calculated by Shannon-Viener Index respectively. The relationships of the 34 genera based on their distribution in 48 sites, and the relationships of the 48 sites based on their similarities of fungaldistribution were analyzed by UPGMA method. It was showed that the UPGMA method was valuable for theanalysis of micromycetes and their niches. UPGMA dendrograms demonstrated the change pattern of niche breadths among the 34 genera of micromycetes and the clustering characteristics of 48 sites.
