Abstract

This study aimed to investigate the community structure and distribution pattern of Gastropods in the mangrove ecosystem Bolihutuo village. The study was conducted in February and July 2021 in two different stations. Community structure analysis carried out includes species composition, density, diversity, evenness, dominance, and distribution patterns by Morisita dispersion index. The results showed that 13 species of gastropods were found from 8 families, namely Cassidula nucleus, Littoraria palescens, Chicoreus capucinus, Nasarius distortus and Phrontis polygonata, Nerita planospira, Faunus ater, Pirenella alata, Cerithidea obtuse, Telescopium Telescopium, Terebralia palustris, Terebralia sulcata and Monodonta labio. Gastropod diversity of each station in June was relatively higher than observations in February. The distribution of Gastropods has a clustered, random, and uniform pattern.Keywords: Community structure; distribution pattern; Gastropods; Mangrove; Bolihutuo

Abstract

This research aims to identify the structure of the bivalve community on the coast of Langkat Village, Pinolosian, South Bolaang Mongondow District. Sampling was carried out from December 2020 to January 2021 at three stations, namely seagrass beds (station I), tourist attractions (Station II), and mangroves (Station III), using the quadrant transect method, where each observation station made a line transect from the mainland towards the sea. Line transects are placed at each station, while the distance between line transects is 50 m. Observation results show that the bivalves at the research location consist of five families (Arcidae, Asteridae, Cyprinidae, Cardiidae, Ostreidae) an six types of bivalves, where the diversity index is low and the uniformity index is moderate, indicating that the distribution of each type is relatively even.Keywords: Bivalve; coastal; community structure; Lungkap

Abstract

The Bone River faces potential pollution due to human activities in the surrounding area. To ensure this, macrozoobenthic is used as a bioindicator, utilizing the characteristics of its constituent communities, which show sedentary behaviour, limited mobility, and sensitivity to water conditions. This research aims to examine the composition of the macrozoobenthic community which reflects the water quality of the Bone River. The research was conducted from May to August 2023 at three observation stations. Water quality evaluation used the Hilsenhoff Family Biotic Index (FBI) methodology. The findings revealed a collection of 1,040 individuals representing 43 macrozoobenthic genera, with Trichoptera, Ephemeroptera, and Diptera widely distributed along the river. A dominance index of 0.2 indicates that there is not a single macrozoobenthic species that dominates, while an FBI value ranging from 3.71 to 5.47 indicates that there is pollution in the Bone River.Keywords: Bioindicator; Family Biotic Index; Macrozoobenthic; River; Water quality
