Abstract

Pulau Lembeh merupakan bagian dari wilayah administratif Kota Bitung, Provinsi Sulawesi Utara, Indonesia. Secara administratif, pulau ini terbagi menjadi dua kecamatan, yakni Kecamatan Lembeh Utara dan Kecamatan Lembeh Selatan. Masyarakat yang tinggal di Pulau Lembeh sangat bergantung pada transportasi laut, terutama kapal, untuk mendukung aktivitas sehari-hari mereka. Aktivitas-aktivitas tersebut berpotensi mengganggu keseimbangan ekosistem, khususnya mengancam populasi plankton Plankton, organisme kecil yang hidup di perairan, memiliki peran penting dalam ekosistem perairan. Mengubah bahan anorganik menjadi organik dan memproduksi oksigen, serta menjadi indikator kualitas perairan. Informasi tentang plankton di Kawasan Perairan Batu Lubang Lembeh Selatan, Kota Bitung, masih terbatas, sehingga penelitian tentang inventarisasi jenis zooplankton perlu dilakukan. Hasil penelitian menunjukkan bahwa terdapat 8 genus zooplankton dari kelas Copepoda di Perairan Batu Lubang Lembeh Selatan Bitung Perairan. Suhu rata-rata perairan berkisar antara 28,04°C hingga 28,59°C, yang normal untuk ekosistem perairan. Salinitas, yang juga penting bagi kehidupan plankton, berada dalam kisaran yang normal di stasiun penelitian. Penelitian ini memberikan pemahaman yang lebih baik tentang komposisi zooplankton dan kondisi lingkungan di Perairan Batu Lubang Lembeh Selatan Bitung, serta menyoroti pentingnya pemantauan terus-menerus terhadap kesehatan ekosistem perairan.

Abstract

The Brachionus plicatilis species complex comprises a group of rotifers commonly found in marine and brackish water environments worldwide. This group has garnered substantial attention due to its ecological significance and its utility in aquaculture research. Notably, the B. plicatilis sp. complex is renowned for its remarkable genetic diversity, which has been extensively investigated through molecular and taxonomic studies. Various genetic markers, including ribosomal DNA and mitochondrial DNA, have been employed to identify several distinct genetic lineages within the B. plicatilis sp. complex. Understanding the taxonomy and phylogenetic relationships within the B. plicatilis sp. complex holds significant implications for its application in aquaculture and ecotoxicology research. In this study, we conducted an analysis of the mitochondrial DNA cytochrome c oxidase subunit I (COI) gene using a dataset of 305 sequences, including four Indonesian rotifers belonging to the B. plicatilis sp. complex. These rotifers were obtained from Sulawesi Island (MNBO and MNSL), Bali Island (AY785226), and Sumatra Island (LMPG). Our primary objective was to determine their phylogenetic positions relative to molecular data available in the GenBank database. We calculated genetic distances among these rotifers using the Tamura Nei model. The results of Maximum Likelihood tree analyses revealed distinct clustering patterns among the Indonesian rotifers. Those originating from Sulawesi Island (MNBO and MNSL) and Bali Island (AY785226) formed the SS1 group (B. ratundiformis), whereas those from Sumatra Island (LMPG) comprised the SM2 group (B. koreanus). This study underscores the importance of molecular phylogenetic analysis in advancing our comprehension of the diversity and evolutionary relationships within the B. plicatilis sp. Complex.Keywords:PhylogenyRotiferaBrachionus plicatilisSpecies complexIndonesia

Abstract

The Isognomon (Lightfoot, 1786) is a genus of oysters found in various coastal ecosystems throughout the world. Along with other bivalves, it performs significant ecological functions in marine ecosystems by providing food and habitat for fish and invertebrate habitats, filtering water, and protecting shorelines. Taxonomic classification of the Isognomon oyster can be challenging due to the varied or cryptic phenotypic characters, particularly shell characters.  In this study, two specimens with different shell characters of Isognomon oyster were collected from mangrove waters in Likupang, North Sulawesi, Indonesia, and subjected to molecular analysis to determine their identity.  The mitochondrial cytochrome C oxidase subunit I (COI) gene was utilized as a primer for this purpose, and the genetic distance and phylogenetic position of the two specimens were determined by comparing them with the GenBank database. The Basic Local Alignment Search Tool (BLAST) revealed that the two specimens were of belonged to Isognomon ephippium, with a similarity of 99.84%. The genetic distance between the two specimens was calculated using the Tamura Nei model and found to be 0.00, while the genetic distance between I. ephippium and other species in the Isognomon genus ranged from 0.00 to 0.14. The results of the Neighbor Joining (NJ) tree analyses showed that the two specimens clustered together with I. ephippium, which was divided into two distinct clades with a strong bootstrap value of 100 at the node
