Gastropod Community Structure in Mangrove Ecosystems on the North Coast of Bangkalan, Indonesia
Gastropods play a vital role in mangrove ecosystems by contributing to the decomposition process through litter fragmentation, which accelerates microbial breakdown. This study aimed to assess the community structure of gastropods in the mangrove ecosystem on the north coast of Bangkalan. Research was conducted from September to November 2022 using a 10x10m² mangrove transect with 3 plots per station, and a 1x1m² transect for gastropods. Gastropods were classified into treefauna and epifauna. A total of 22 species were identified across 14 research stations, including Assiminea ovata,Cassidula aurisfelis, Cerithidea cingulata, Cerithidea obtusa, Littoraria melanostoma, and Turbo setosus. The most frequent epifauna were Cerithidea cingulata and Telescopium telescopium, while Cerithidea obtusa dominated treefauna. The diversity index ranged from 0.36 to 1.94, the evenness index from 0.33 to 0.97, and the dominance index from 0.18 to 0.78, indicating a moderately stable ecosystem. Simple linear regression analysis revealed a weak relationship between gastropod abundance and mangrove density (r = 0.14, R² = 0.02), suggesting minimal correlation between the two variables. Overall, the gastropod community structure was classified as moderate.
