"Gastropoda merupakan spesies laut yang ditemukan di perairan Pulau Pramuka di Taman Nasional Kepulauan Seribu Jakarta Indonesia. Informasi tentang hubungan antara kompleksitas struktur habitat dan komunitas gastropoda di daerah ini belum banyak diketahui. Tujuan dari penelitian ini adalah untuk mengetahui jenis spesies gastropoda dan pengaruh faktor abiotik seperti pH air, suhu air, salinitas air dan intensitas cahaya terhadap komunitas gastropoda serta kontaminasi mikroplastik pada Terebralia palustris. Jumlah spesies gastropoda yang ditemukan menghuni daerah terpilih di Pulau Pramuka hanya lima (Telescopium telescopium, Terebralia palustris, Cerithium coralium, Nerita planospira, dan Littorina scabra). Daerah mangrove terpilih tercatat sebanyak 508 individu di kedua stasiun. Keanekaragaman spesies gastropoda tercatat memiliki nilai indeks rendah (H′ = 0,57), sedangkan kemerataannya berada pada kategori rendah (E = 0,35). Kondisi ini menimbulkan kekhawatiran akan potensi dominasi spesies tertentu dalam jangka panjang, dengan nilai dominasi yang tinggi (C = 0,78) tercatat berdasarkan data yang terkumpul di Pulau Pramuka. Pencemaran mikroplastik laut telah menimbulkan banyak dampak terhadap spesies laut dan pada pemeriksaan mikroplastik dengan menggunakan 3 sampel T. palustris yang dikumpulkan dari ekologi mangrove di Pulau Pramuka, ditemukan berbagai bentuk partikel mikroplastik yang meliputi serat, fragmen, pelet dan transparan serta berbagai warna. Bentuk mikroplastik yang paling banyak terdeteksi adalah serat yang tercatat sebanyak 53 partikel atau sebesar 96% dari total bentuk mikroplastik yang terdeteksi. Temuan penelitian ini menunjukkan bahwa terdapat pengaruh mikroplastik berbasis serat yang rumit pada ekosistem laut ini.

Gastropods are marine species found in the waters of Pramuka Island in Kepulauan Seribu National Park Jakarta Indonesia. Information on the relationship between habitat structural complexity and gastropod communities in this area is not widely known. The purpose of this study was to determine the types of gastropods species and the influence of abiotic factors such as water pH, water temperature, water salinity and light intensity on gastropod community as well as microplastic contamination on Terebralia palustris. The number of gastropod species found inhabiting the selected area in Pramuka Island was only five (Telescopium telescopium, Terebralia palustris, Cerithium coralium, Nerita planospira, and Littorina scabra). The selected mangrove area recorded a total of 508 individual in the two stations. The diversity of gastropod species recorded a low index value (H′ = 0.57), while the evenness was in a low category (E = 0.35). This condition raises concerns about the potential domination by certain species in the long run, with a high dominance value of (C = 0.78) is recorded based on the data collected in Pramuka Island. Marine microplastic pollution has cause a lot of impacts on marine species and during the microplastic examination by using the 3 samples of T. palustris that were collected from the mangrove ecology in Pramuka Island, there were different forms of microplastic particles found which includes fiber, fragment, pellet and transparent and different colors. The most detected microplastic form was fiber which recorded 53 particles amounting to 96% of the total microplastic forms detected. The present finding in this research has indicated that there is intricate influence of fiber based microplastic in this marine ecosystem. "

"The diversity, ecological role and biotechnological applications of marine fungi have been addressed in numerous scientific publications in the last few years. This book addresses this need. The latest information on topics including molecular taxonomy and phylogeny, ecology of fungi in different marine habitats such as deep sea, corals, dead- sea, fungi in extreme marine environments and their biotechnological applications is reviewed.
