A new device to sample freshwater benthic macroinvertebrates was used in a low and sandy stretch of a Brazilian sub-tropical river (the River Caí, Triunfo, RS) and in one of its small tributaries, Bom Jardim brook (Arroio Bom Jardim). In this study, the effectiveness of this device, a PET sampler, was tested at different sites in the river and the brook throughout the four seasons between 2001-2002. Comparisons were made by PCA and ANOVA, both employing a bootstrap procedure based on similarity matrices. The PET sampler proved to be a reliable tool for detection of seasonal and spatial differences in richness, total abundance of organisms, and Shannon's diversity index in both river and brook and is therefore recommended for use in the monitoring of macroinvertebrate communities in this system.

Benthic macroinvertebrates are used as environmental bioindicators in the assessment of water quality in rivers and lakes, due to the sensitivity of some taxa to pollution. The objective of this research was to evaluate the consequences of industrial effluent discharge on the structure of the benthic community present in a river in the subtropical region of Brazil. The organisms were collected at three points of the Coutinho River, in 2013 (September and November) and 2014 (January and March). To characterize the community were calculated density, Shannon diversity index (H´), Pielou equitability (J), taxa richness, Biotic Indices (Biological Monitoring Working Party - BMWP, Average Score Per Taxon - BMWP-ASPT, Family Biotic Index – FBI) and Canonical Correspondence Analysis (CCA) between sampling points and biotic and abiotic variables. Fifteen taxa were identified and among the collected organisms, the family Chironomidae was the most representative, followed by Oligochaeta, Hirudinea, Bivalvia, Gastropoda. According to the results of the biological indices, point 1 indicated moderate pollution and the following points (2 and 3) showed severe pollution. These indices showed poor waters with a high degree of pollution. The results were efficient in detecting the environmental impacts suffered by the river and suggest the necessity of a continuous monitoring of the same.

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.

An assessment of community of benthic macroinvertebrates in waters northwards of Pulau Indah, Klang was made with the main objective to determine distribution and diversity of benthic macroinvertebrates as well as to establish possible correlation between the community’s distributions with environmental parameters. The sediments were obtained via Ponar Grab (0.023 m2 mouth area), followed by filtration (500 μm) and laboratory sorting in order to extract all specimens from sediments. The specimens were identified to the lowest taxonomic hierachy as possible. The physical parameters such as organic carbon (TOC) and grain size distributions were analysed. A total of 775 annelids, 15 arthropods, 12 echinoderms and 32 molluscs individuals were identified and recorded in six stations overall. Family Cirratulidae accounted to the highest numbers of the Annelids (n=358), whilst Cerithidae recorded as highest numbers of Molluscs. Station 5, 6 and 1 recorded the highest diversity index (H’=2.1845), evenness index (J’=0.6316) and richness index (Dmn=22.0454) respectively. Principal Component Analysis indicated sediment particle size as the major connector on all stations, with different station correlated to certain sizes of sediment particle. Pearson correlation analysis showed positive correlations between environmental parameters with eight benthic taxa in this study, with most correlations were on specific sediment particle size. As the study of benthic community is still inadequate in most of Malaysians waters, particularly in highly industrialised area such as waters in Port Klang, this study can serve as a starting point for any future studies concerning ecological disturbance affecting benthic community in Malaysian waters.

A study on macroinvertebrate diversity was conducted in Sungai Kisap, Langkawi, Kedah. Five stations were selected with a distance of approximately 500 metres apart with three replications of benthos and two replications of water sample. The results classified Sungai Kisap in Class I, which indicates very good water quality based on WQI recommended by the Department of Environment. A total of 2 phyla, 3 classes, 8 orders, 29 families, and 3564 individuals were successfully sampled and recorded. The presence of Hydropsychidae, Baetidae, and Chironomidae with a high abundance of the families show the potential to be used as biological indicators of a clean ecosystem. The analysis showed that the average value of Shannon Diversity Index, H’ (1.28), Pielou Evenness Index, J’ (0.45), and Margaleff Richness Index, DMG (2.80) indicates that Sungai Kisap is in moderate condition and the distribution of macroinvertebrates is uniform between stations. The correlation test showed that the WQI has a strong relationship with the diversity indices involved. BMWP, ASPT, and FBI showed that Sungai Kisap has good water quality.

In this study, it was aimed to evaluate the water quality of the Çoruh Basin using BMWP (Biological Monitoring Working Party) index, ASPT (Average Score Per Taxon) index, Shannon-Wiener Diversity Index, EPT (Ephemeroptera Plecoptera Trichoptera taxa), EP (Ephemeroptera Plecoptera taxa) index scores and benthic macroinvertebrates. The benthic macroinvertebrates were collected from 54 stations at the Çoruh basin between 2014-2016 years. Standard hand net (D-frame net) and Ekman-Birge grab were used as sampling tools. As a result of the diagnoses, a total of 7246 individuals belonging to Insecta, Crustacea, Mollusca, Oligochaeta and Plathyhelminthes were obtained. It was determined that the most dominant group was Insecta and the rarest group was Plathyhelminthes. It was observed that the BMWP score ranged between 5 and 94, and the lowest and highest number of families detected in the stations were 1 and 18, respectively. It was determined that the Shannon Wiener diversity index value was between 0.54-2.20, therefore the basin streams generally showed moderate pollution. The results of BMWP index show that the basin streams had mostly show 3rd and 4th class water quality and also biodiversity decreases with the deterioration of the riverbed or exposure to pollution.

ResumenPara determinar los cambios espacio temporales de las variables bióticas y abióticas que modifican la estructura de los macroinvertebrados bentónicos, se establecieron 6 estaciones de monitoreo distribuidas en el trayecto de la parte alta (Municipio de Pamplona -media (Municipio de Cúcuta)) del río Pamplonita. El muestreo se realizó durante 7 meses, para un total de 42 muestras distribuidas durante los periodos bimodales de lluvia y sequía. El tipo de investigación fue descriptiva y aplicada. Se obtuvieron los índices de contaminación por materia orgánica (ICOMO), Índice de Contaminación por Mineralización (ICOMI) e Índice de Contaminación por pH (ICOpH). La estructura de la comunidad bentónica se analizó mediante el índice de diversidad (Shannon-Weiner). Finalmente se validó el modelo matemático (Índice de Tolerancia frente un gradiente de contaminación por materia orgánica), a partir de las relaciones definidas entre las variables bióticas y abióticas. Los resultados del ICOMO reflejaron que la estación del terminal de Pamplona localizada a una altura de 2295 m.s.n.m., es la de mayor carga de materia orgánica con un promedio de 0,79, con un índice de diversidad de Shannon, promedio de 0,63, de diversidad muy baja.

AbstractLittoral benthic macroinvertebrates of 45 mountain lakes in the Tatra Mountains were sampled using a semi-quantitative method in September 2000. A total of 32,852 specimens were identified to 93 taxa belonging to 14 higher taxonomic groups. Multivariate statistics (CCA, RDA) and nine biotic metrics (AQEM/STAR) were used to explain relationships between macroinvertebrate assemblages and environmental variables. Up to 57% of the ecological position of littoral macroinvertebrate assemblages were explained by variance of environmental variables divided into chemical, trophic, physical, catchment and location. Five types of Tatra lakes were recognized using CCA: A — strongly acidified lakes (small catchment, low pH, high concentration of TP, DOC, highest amount of POM in littoral); B — alpine acidified lakes (low amount of POM, low values of biotic metrics); C — alpine non-acidified lakes (high value of diversity index, predominance of Diptera); D — subalpine acidified lakes (high values of biotic metrics: number of families, proportion of crenal and rhithral taxa/total taxa); E — subalpine non-acidified lakes (high values of biotic metrics: number of families, number of genera, BMWP score, number of taxa and abundance of EPT taxa). RDA was used to design five levels of macroinvertebrate taxa acidification tolerance. The Tatra Acidification Index (TAI) was established to assess the acidification status of the lakes in the Tatra Mts.
