ความสัมพันธ์ของความมากชนิดและองค์ประกอบชนิดของไบรโอไฟต์ในชนิดของถิ่นที่อยู่ที่แตกต่างกัน / Associations of Species Richness and Composition of Bryophytes to Different Habitat Types

The goal of this study was to find associations of species richness and composition of bryophytes with different habitat types in Khao Chong Forest Dynamic Plot, Trang Province. The plot was divided into 4 habitat types, based on the cluster analysis of elevation, slope, convexity and basal area. The four habitats included valley, slope, below-ridge and ridge. In each habitat type, ten random plots of 10×10 square meters were chosen. In each sampling plot, the samples of bryophytes were collected from various substrates, including trees, rock, soil, logs, leaves, and lianas. The samples were identified to the species level. A total of 77 species, belonging to 42 genera, and 24 families of bryophytes were found. This included 49 species of mosses, 27 species of liverworts, and 1 species of hornworts. In all four habitat types, the number of moss species was higher than liverworts, and thalloid liverworts and hornworts only occurred in the valley. However, there was no significant difference in species richness and composition among the four habitat types.
