Abstract

Bryophyte communities were compared between arboreal (trunk bases) and terrestrialhabitats in primary forest Mount Halimun Salak National Park, West Java. The communitieswere analyzed based on species diversity, abundance, and biomass. A total of 150 bryophytesspecies were identified, including 67 species of mosses (Bryopsida) and 83 of liverworts(Hepaticopsida). Both bryophyte groups varied in diversity and abundance between arborealand terrestrial communities as well as among different elevations. Species diversity of arborealhabitats (116 species)was higher than that of terrestrial habitats (64 species). Moss speciesweremore abundant in terms of coverage in terrestrial habitats whereas liverworts species weremore abundant in arboreal habitats. Species richness in both terrestrial and arboreal habitatsdecreased towards higher elevation, whereas the abundance increased.

Abstract

Study on the Hepaticae (Liverworts) of Sumatra is very scanty including the knowledge on the genus of Marchantia (Marchantiaceae). This study was conducted to explore the diversity of Marchantia in Mount Sibayak North Sumatra, Indonesia. There are seven species of Marchantia in Mount Sibayak North Sumatra, five of the species are previously known: Marchantia acaulis, M. emarginata, M. geminata, M. paleacea, and M. treubii; two of the species are new records for Sumatra (M. polymorpha and M. rubribarba). An identification key of the genus Marchantia from Mount Sibayak, North Sumatra is provided.Key words: Marchantia, Mount sibayak, North Sumatra
