Abstract

Research on the role of benthic substrates in shaping hermit crab communities along coastlines remains relatively limited, despite the important role this group plays in coastal benthic ecosystems. This study counducted in April 2025, aimed to examined the relationship between substrate characteristics sand, coral rubble, and coral reefs and the distribution and community structure of hermit crabs of the family Diogenidae along the northwestern coast of Tarahan Island, Indonesia. A total of 58 individuals consisting of 9 hermit crab species were identified across the three habitat types, with the highest species richness and abundance found in the rubble habitat, which exhibited high porosity and microhabitat heterogeneity. Community analysis using ANOSIMS showed R value of -0.002 and a p-value of 0.48 revealed an overlap in species composition among habitat types however, SIMPER analysis certain species such as Clibanarius striolatus consistently dominated habitats with high structural complexity, while others like Clibanarius signatus showed a specific preference for coral-sand habitats. This variation in habitat preference reflects a spectrum of ecological strategies, ranging from specialists to generalists, within the hermit crab community studied. The findings highlight the importance of substrate diversity and integrity in supporting the ecological flexibility, stability, and sustainability of hermit crab communities in dynamic coastal ecosystems

Abstract

The waters of Banten Province are one of the habitats of Dugong and many other protected species because it is supported by the many seagrass ecosystems found. The purpose of this study was to identify the presence, seagrass beds, dugong, other protected species, and their threats in Banten Waters. Information data regarding the presence of dugong, threats to dugong, community perceptions regarding dugong and seagrass beds, as well as additional information on other protected species (such as turtles, dolphins, sharks and whales) were taken by conducting in-depth interview methods to respondents. The interview questionnaire was based on the CMS-UNEP standardized dugong questionnaire. The number of respondents was determined with a proportion of 70% in locations with strong dugong information and the rest in neighboring locations. The results showed that dugong, dolphins, turtles, sharks and whales were found in Pandeglang Waters. While in Serang Waters dugong, porpoise, dolphin, turtle and whale shark were found. Threats to the life of dugong and other biota in Pandeglang Waters are the presence of gill net fishing gear and sero, if there is a dugong caught, it is not sold for food but sold to Sea World Ancol under the pretext of rescue.  There are two threats in Serang: poachers from the Wadas area and the construction of an international port that changes habitat, pollutes, and can cause accidents. Seagrass beds can be found almost along the entire coast of Pandeglang and Serang. The main threat to seagrass beds is environmentally unfriendly coastal change.
