| Abstract: | This study explored the bole epiphytic bryophytes in the tropical rainforest and the tropical montane evergreen broad-leaved forest in Xishuangbanna,aimed to reveal their composition,diversity patterns,and maintenance mechanisms.The study site is located in Mengla County.Ten sampling plots(20 m×20 m)of each vegetation type were chosen,and about ten tree individuals were sampled in each plot to survey the bole epiphytic bryophytes.The results were as follows:(1)In total,60 species belonging to 39 genera and 20 families were recorded.Among them,48 species belonging to 33 genera and 19 families were recorded in the tropical rainforest,and 19 species belonging to 14 genera and 9 families were recorded in the tropical montane evergreen broad-leaved forest.(2)The dominant family of the tropical rainforest is Neckeraceae,while the dominant family of the tropical montane evergreen broad-leaved forest is Sematophyllaceae.(3)The species richness,βandγdiversities of the tropical rainforest were higher than the tropical montane evergreen broad-leaved forest.(4)The coverage of epiphytic bryophytes was significantly different among different diameter classes and bark roughness.(5)Pendants,fans,wefts,and rough mats prefer the tropical rainforest,while turfs,cushions,smooth mats gather in the tropical montane evergreen broad-leaved forest.(6)The results of redundancy analysis showed that host characteristics,especially bark roughness,significantly affected the composition and distribution of life forms.Tropical rainforest provide a greater diversity of microhabitats than tropical montane evergreen broad-leaved forest,and thus harbor more epiphytic bryophyte species than the latter.Considering different bryophyte life form were recorded in different vegetation types or host characteristics,life forms can be considered as an important indicator for forest monitoring and management. |
