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.

Abstract

Studies on microdebris contamination in sediments at the estuary of the Pangkajene River were carried out at three stations. This study aims to observe the abundance and characteristics of microdebris in the estuary sediments of the Pangkajene River. The samples of sediment were collected using a core sampler with a diameter of 8 cm. Microdebris was extracted using the flotation method and vacuum filtration system. The particles were observed with a stereomicroscope then classified based on shape (form), size, and color. The number of particles found ranged from 2.83±2.04-4.00±1.87 item/100gr. The analysis of variance (ANOVA) showed p>0.05, therefore the abundance of microdebris between the three stations did not show a significant difference. Microdebris in Fragment form had the highest percentage compared to fibers and granules. Blue and black particles of microdebris were the most common colors. The dominant size of particles was found in the size class <100µm and 100µm-500µm. This preliminary study revealed that the microdebris occurs in the Pangkajene estuary sediments. Currently, we have not classified the types of microdebris found as microplastic, semi-synthetic debris, or natural origin. Therefore, further research is needed to verify particles using an FT-IR Microscope to determine the type of microdebris polymer.
