AbstractThe research had been done for structure community of Gastropods at mangrove ecosystem in complex Pari's Island, Seribu Islands on July 2010. The purpose for this particular descriptive analysis research was to know the composition, density, diversity, evenness, domination, distribution, similarity and it?s correlation with abiotic parameters. Samples were taken by using purposive sampling and transect square method on three islands, namely Pari Island, Tengah Island and Burung Island. The abiotic parameters were measured (temperature, salinity, depth, and organic matter). We found 33 species of gastropods, which they were divided into three groups, namely native (6), facultative (2), and visitor (25) species molluscs of mangrove, respectively. The highest density was found in the Tengah island (112,48 ind/m2) and the lowest in the Burung Island (66,19 ind/m2). Terebrealia sulcata was Gastropod with the highest density (31,6 ind/m2). The highest diversity index occured at Burung Island (1,978) and the lowest at Pari Island (1,497). In general the distribution of Gastropods at mangrove ecosystem in complex Pari?s Island was clumped distribution pattern and no species domination. The highest similarity index found in substation P1 and T1 (92,74%), while the lowest found in T3 and B8 (14,65%). The mud and total organic matter (TOM) has a positive correlation to Gastropods density. "

Polychaeta is a group of invertebrates which is important in the marine food chain, particularly for demersal fishes, shrimps, and crabs. Polychaeta lives in various habitats, in muddy, sandy, and stony bottoms. Information about Polychaeta in Indonesian waters, especially in Maluku waters, has not yet been known well. Based on those fact, a research on the community structure and distribution of Polychaeta of mangrove forest in the waters of Kotania Bay was conducted in February 1996. Samples were collected from five stations using a transect method. The aim of the study was to find out the relationship of Polychaeta community structure with the environmental factors in Kotania Bay. The distribution of Polychaeta of mangrove forest in Kotania Bay was also studied. Hopefully, the results of this study can be used as basic information for futher research. During the study, 40 species of Polychaeta belonging to 36 genera of 13 families were collected from the locality. Two species showed high frequency of occurrence (89%), i.e. Pa/lie/la sp and Armandia infermedia. This indicated that the two species were common and distributed more widely than the others. The highest' density of Polychaeta was in Burung Island (21.307 indlm3) and the lowest was in Pelita Jaya 1 (12.102.ind/m3). The highest density of Polychaeta in Burung Island was mainly due to the highest density of Pulliella sp, Armandia intermedia, and A. lepfocirrus. The highest diversity and evenness indeces of Polychaeta species were found in Buntal island. Tatumbu Island and Burung Island had the highest similarity index. The water conditions of Kotania Bay showed that salinity ranged from 22,5°100 to 27°1°0, temperature ranged from 29,5°C to 31°C, and pH varied between 7,8 and 8,4. Substrates mostly contained sand with the very high percentage of very coarse sand. Cluster analysis divided the five station into two groups : Group 1, defined by Tatumbu Island and Burung Island, and Group II, defined by Pelita Jaya 2, Buntal Island, and Pelita Jaya 1. Discriminant analysis also divided the stations into two groups. Medium sand in the substrat was responsible in separating the five stations into two different communities. Factorial Correspondence Analysis (CA) classified the species of Polychaeta into four group based on species densities and specification of species in the location."
