Habitat identification and phenetic analysis of Bryophyta in Lampung, Indonesia

Moss plants are the second largest group after tall plants, numbering approximately 18,000 species and spread throughout the world. Information regarding the kinship relationship between mosses is still limited, so it is necessary to identify the habitat and phenetics of mosses. The purpose of this study was to identify the habitat and kinship of mosses. The research method used is a exploring method in several districts in Lampung province, those are Pesawaran, Metro, and Way Kanan. The data collected is the morphology of the mosses found and their substrates. Data were analyzed using cluster analysis with software Multivariate Statistical Package (MVSP.) version 3.2 and genetic distance using the Unweighted Pair-Group with Arithmetic Average (UPGMA) method. Furthermore, to determine the morphological characters that affect the grouping between species, the Principal Component Analysis (PCA) method is used. The results showed that around 45-70% of moss species were found around the rocks and in humid places with a height of 3-7cm at a temperature of around 27.5-30°C and a pH of 6-7. The kinship relationship between 5 accessions of mosses has a similarity index between 0.22-1.00 and four characters play an important role in grouping leaf mosses, namely height, root, leaf color, and leaf tip.
