Abstract

Information about marine isopods in Indonesian water is scarce. This research aimed to inventory isopods in nearshore habitats of Northern Sulawesi using a morphological approach to identify the species. Sampling was done in several spots in Bangka Island considering three different habitats: coral rubble, mangrove roots, and seagrass beds. These habitats are known to be suitable for isopods to feed, reproduce, and hide from bigger predators. There is 7 group of Isopod found in totals, such as Anthuridea, Asellota, Bopyridae, Cirolanidae, Gnathiidae, Limnoriidea, and Sphaeromatidea. In the family of Anthuridae, there are 2 suspected new species and required further identification.Keywords: Marine Isopod, Ecology, Bangka Island, North Sulawesi.AbstrakInformasi mengenai isopoda laut di perairan Indonesia masih sangat sedikit. Penelitian ini bertujuan untuk menginventarisasi isopoda di habitat dekat pantai Sulawesi Utara menggunakan pendekatan morfologi untuk mengidentifikasi spesies. Pengambilan sampel dilakukan di beberapa titik di Pulau Bangka dengan pertimbangan tiga jenis habitat berbeda: serpihan karang, akar mangrove, dan padang lamun. Habitat tersebut merupakan tempat isopoda mencari makan, bereproduksi, dan bersembunyi dari predator. Dari hasil identifikasi ditemukan 7 kelompok isopoda, yakni  Anthuridea, Asellota, Bopyridae, Cirolanidae, Gnathiidae, Limnoriidea, dan Sphaeromatidea. Diduga ada 2 species yang baru di kelompok Anthuridae yang masih perlu penelitian lebih lanjut.Kata kunci: Isopoda Laut,  Ekologi, Pulau Bangka, Sulawesi Utara.

Abstract

Plankton communities play a crucial role in marine ecosystems and are widely used as bioindicators of environmental quality. This study aimed to map plankton community structure in several coastal waters of North Sulawesi and evaluate their potential as indicators of marine ecosystem health. Plankton samples were collected from Bunaken, Lembeh Strait, Amurang, Belang, and Likupang using standard plankton net tows. Community structure was analyzed using species composition, abundance, Shannon–Wiener diversity index (H′), evenness (E), and dominance (D). The results showed clear spatial variation in plankton community structure among study sites. Higher diversity values were recorded in Bunaken (H′ = 2.78; E = 0.81; D = 0.18) and Lembeh Strait (H′ = 2.65; E = 0.79; D = 0.21), indicating relatively stable marine conditions. In contrast, Likupang exhibited lower diversity and higher dominance (H′ = 1.43; E = 0.52; D = 0.39), suggesting greater environmental stress. These patterns demonstrate that plankton community indices are sensitive indicators of ecosystem condition in tropical coastal waters. The findings also highlight the potential use of plankton ecological data as contextual learning resources in science education, particularly for teaching marine ecosystem dynamics, biodiversity, and environmental monitoring using real environmental datasets from local coastal ecosystems
