Invertebrate Community Structure

Situ Cibuntu, is one of urban ponds located in Bogor Regency, West Java. With a maximum surface area of 11 ha and maximum depth of 1,20 m, the pond serves as irrigation for nearby agricultural fields and recreational fishing. Located in relatively high urban pressure, the pond is highly affected by domestic, agricultural and industrial inflow which can influence the biotic community such as benthic macroinvertebrate. We studied benthic invertebrate community structure in Situ Cibuntu from October to November 2018 to determine the role of environmental factors on benthic macroinvertebrates. Samples were collected biweekly from five sampling points using an Ekman sediment grab with three replicates. Our study revealed 16 species of benthic macroinvertebrates belonging to four classes including Gastropoda, Bivalvia, Clitellata, and Insecta. Melanoides tuberculata species was found to have the highest abundance with an average abundance of 858 individuals/m2. Shanon-Wiener Diversity Index shows a relatively low diversity ranged from 0.61 to 1.26, while evenness index ranged from 0.36 to 0,66. Simpson Dominance Index ranged from 0.24 to 0.93.Keywords:DominanceCommunityAbundanceDiversityBenthic MacroinvertebratePond CibuntuABSTRAKSitu Cibuntu merupakan salah satu situ urban (urban pond) yang terletak di Kabupaten Bogor, Provinsi Jawa Barat. Situ Cibuntu yang memiliki luas permukaan 2,11 ha dengan kedalaman maksimum 1,20 m dimanfaatkan sebagai sumber irigasi pertanian dan sarana pemancingan ikan. Situ di kawasan perkotaan dapat mengalami tekanan karena pengaruh limbah domestik, pertanian, dan industri yang dapat mempengaruhi komunitas biotik seperti makroinvertebrata bentik. Penelitian ini bertujuan untuk mengetahui komunitas makroinvertebrata bentik di perairan Situ Cibuntu. Penelitian dilakukan pada bulan Oktober hingga November 2018 di lima stasiun pengamatan. Pengambilan sampel dilakukan sebanyak tiga kali dengan interval waktu dua minggu. Sampel makroinvertebrata bentik diambil dari sedimen pada setiap stasiun dengan menggunakan Ekman grab sebanyak tiga kali ulangan. Secara keseluruhan ditemukan 16 spesies makroinvertebrata bentik yang tergolong ke dalam empat kelas meliputi Gastropoda, Bivalvia, Clitellata, dan Insekta. Spesies Melanoides tuberculata memiliki kelimpahan tertinggi dengan nilai rata-rata sebesar 858 individu/m2. Keanekaragaman makroinvertebrata bentik tergolong rendah hingga sedang dengan nilai indeks Shanon Wiener (H’) berkisar 0,61-1,26. Nilai indeks kemerataan Pielou (E) berkisar 0,36-0,66, sedangkan indeks dominansi Simpson (D) berkisar 0,24-0,93.Katakunci:DominansiKomunitasKelimpahanKeanekaragamanMakroinvertebrata bentikSitu Cibuntu

Benthic Invertebrate Community

The aim of environmental study is to investigate the effects of the discharge of Wasit power plant in Al-Zubaidiya city on the physical- chemical factors and biodiversity of benthic invertebrates community of Tigris River, for a period from October 2017 to Augusts 2018. The total number of benthic invertebrates in four stations was 12866 individual. These benthic invertebrates  belonged to 8 taxonomic units. This study includes some statistical environmental indexes (Relative abundance index, Shannon-Weiner Diversity Index, Species Uniformity Index, Species Richness Index and Jaccard Index). The results reveal that the environmental indexes were decreased at station 2 and thermal Wasit power plant negatively effects benthic invertebrate community at station 2 near the effluent waste pipe site.

Temporal Flow

A study was conducted in four streams in the same watershed in New York to determine whether the benthic invertebrate community structure varied among streams with different temporal flow regimes. Timed kick samples were taken from 13 riffles and 4 pools once a month from June to November 1982. Riffle sites were classified according to temporal flow regime as permanent, intermittent (dry for less than 3 months), or dry (dry for over 3 months), and varied in size as a function of discharge. Ordination analysis (detrended correspondence analysis) showed that the structure of the benthic invertebrate communities in these streams was related not only to riffle permanence, but also to other abiotic and biotic parameters. Differences in community structure were greater between adjacent pools and riffles than between temporary and permanent riffles. Stream size, seasonal changes in taxa, how recently the riffle had dried, and the length of the dry period contributed to differences in community structure among riffles. It appears that differences in community structure between permanent and temporary riffles are minimized by generalized adaptations of stream benthos, such as high rates of migration, drought-resistant eggs, and the tendency to take refuge in the hyporheic zone.
