| Abstrak (Bhs. Indonesia) | Mangrove and associated molluscs of infamous Raja Ampat Indonesia were studied and aimed to determine the community structures of both mangrove and associated mollusc including the correlation with their environmental factors. In addition carbon sequestration were also estimated . Mangrove community structure and carbon sequestration were determined by collecting samples using 10 m x 10 m, 5 m x 5 m and 1 m x 1 m quadrates for tree, sapling and seedling respectively. Mangrove associated Molluscs were sampled using a 100 m2 quadrate and 3 random replicates were applied within each vegetation sample quadrate. Density of mangrove tree, sapling, and seedling in research area of Raja Ampat were found 1214.29 ind/ha, 2285.71 ind/ha, and 52380.95 ind/ha respectively. Mangrove diversity comprissed of Brugueira gymnorrhiza, Rhizophora mucronata, Rhizophora apiculata, Sonneratia alba, and Ceriops tagal. Mangrove trees were significantly related to environmental factors such as salinity, fraction of substrate texture i.e. sand, loam and clay; while mangrove saplings and seedlings were found having no relationship with any of measured environmental factors. The density of mangrove associated molluscs in study area of Raja Ampat were found 13, 89 ind/m2 composed of 12 gastropod species Terebralia sulcata, Amiantofusus pacificus, Fusus thilei, Clypeomerus pellucida, Nerita planosphira, Nerita maura, Nerita insculpta, Cassidula vestertilionis, Cassidula aurisfelis, Littoraria lutea, Littoraria angulifera and Monodonta labio, and 3 bivalvia species Codakia tigerina, Polymesoda erosa, and Polymesoda expansa. The community structure of mangrove associated molluscs was found significantly related to environmental factors such as temperature, salinity, and fraction of substrate texture i.e. sand and clay. Molluscs were found having significant relationship with mangrove trees, but not with sapling and seedling. The carbon sequestration in Raja Ampat mangrove communities were found in a very huge amount of carbon at 139.35 ton/ha in total composed of 89.64% above ground and 10.36% below ground. |
