Abstract

Gastropoda merupakan salah satu biota asosiasi mangrove yang sangat penting untuk dikaji struktur komunitasnya karena dapat digunakan sebagai bioindikator sebuah ekosistem. Penelitian ini dilaksanakan pada tanggal 27 Maret 2022 di Pulau Pannikiang, Madello, Kecamatan Barru, Kabupaten Barru, Sulawesi Selatan yang bertujuan untuk menganalisis kepadatan dan keanekaragaman gastropoda pada eksosistem mangrove. Teknik pengumpulan data dilakukan pada tiga stasiun berbeda dengan tiga titik berbeda, di mana tiap titik ditempatkan plot kuadran berukuran 1 x 1 meter. Sampel dianalisis untuk memperoleh kepadatan mutlak, indeks keseragaman, indeks keseragaman, dan indeks dominansi. Hasil menunjukkan bahwa nilai kepadatan mutlak berada di angka 6.67-28.33. Nilai indeks keseragaman dan dominansi berada di kategori rendah hingga sedang. Sementara itu, kestabilan komunitas berada di kategori tertekan hingga stabil berdasarkan nilai indeks keseragaman. Ditemukan 13 spesies dari 7 famili di ekosistem mangrove pulau Pannikiang. Hasil analisis kepadatan mutlak stasiun 1 berada di angka 25.00, stasiun 2 memiliki nilai 6.67, dan stasiun 3 memiliki nilai 28.33. Tingkat keanekaragaman dan keseragaman paling tinggi dimiliki oleh stasiun 2 dengan nilai 1.57 (keanekaragaman sedang) dan 0.97 (komunitas stabil). Sementara, indeks dominansi tertinggi ada pada stasiun 1 (0.87).

Abstract

Despite being part of food web and bioindicator in freshwater ecosystems, gastropods are globally jeopardized. Therefore, the occurence of freshwater gastropods need to be assessed. This research aimed to examine diversity and distribution of freshwater gastropods along the Ciapus River in Bogor, West Java, Indonesia. The research was conducted from February to May 2020. Sampling was carried out within limited 15 minutes time period using five 1 × 1 m plots established at each of four survey stations. Gastropods were collected from the bottom of river, rock surface and riverbanks within 15-100 cm of water depth. Environmental parameters were recorded. Data was analyzed using biodiversity index parameters and diversity t-test. The survey collected a total 587 individuals from 7 species of freshwater gastropods. The abundance, species richness and diversity of gastropods in the Ciapus river were different between upstream and downstream, location with high altitude tend to have low number of species. Glyptophysa stagnalis became the only species recorded from upstream area. Meanwhile, there were 4 species, which were collected in other three stations and 2 species that recorded from two stations. In three stations, Tarebia granifera was the most dominant species.
