“…The use of biotic communities for monitoring aquatic environments, especially water quality, has several widely known advantages over physicochemical monitoring (Hering et al 2006;Sharifinia et al 2012a;Findik 2013;Tan et al 2014b). In running waters, where changes in hydrology are rapid and variable, biological monitoring has proved to be useful due to its integrating nature (Atazadeh et al 2007;Miserendino 2009;Varnosfaderany et al 2010;Smucker and Vis 2011;Namin et al 2013a, b;Vidal-Abarca et al 2013;Shokri et al 2014;Nazarhaghighi et al 2014;Tan et al 2014b).…”

The present study analyzed the relationships of two different biological assemblages (diatom and macroinvertebrate) when they are used to characterize a set of stations (from reference stations to impacted stations) within the Shahrood River. In particular, we examined the issue of concordance among these assemblages and the physicochemical parameters detected, using both multivariate and multimetric methods. In addition, the trophic diatom index and Hilsenhoff family-level biotic index for macroinvertebrate assemblages were used to evaluate the ecological status of the Shahrood River. Diatom and macroinvertebrate assemblages in the Shahrood River differed significantly between reference and impacted stations. ANOSIM showed a significant difference in the composition and abundance of diatoms and macroinvertebrates among reference, influence and impact stations, especially between reference and impact stations. Results of CCA ordination showed that benthic diatoms and macroinvertebrate assemblages were mainly affected by DO, TSS, NO 3 -, PO 4 3-concentrations and heavy metals such as Zn and Cd. Biotic indices for the Shahrood River suggested a water quality category of ''fair'' with fairly substantial organic pollution for the impacted stations.Finally, our results suggest that an appropriate management and restoration policy needs to be implemented for the Shahrood basin.

“…The density and biomass of the benthic fauna increased with depth. Oligochaeta dominated in this respect, which is characteristic of most dam reservoirs (Dusoge et al, 1990;Real et al, 1993;Di Giovanni et al, 1996;Shao et al, 2006;Findik, 2013;Georgieva & Uzunov, 2015). The strong dominance of this zoobenthos group has now been recorded at depths of 1 m and 2 m, which seems to be quite surprising, due to the very low organic matter content in the bottom sediments at these sites.…”

Abstract. The aim of the study was to determine the impact of the increase in the organic matter content in the bottom sediments on the benthic fauna structure. The research was carried out in a strongly rheolimnic the Włocławek Dam Reservoir (Poland). The samples were taken on eight dates from March 1988 to February 1989. The sampling sites were located at the following depths: 1 m, 2 m, 5 m, 8 m and 10 m.The organic matter content in the bottom sediments increased with depth from 0.6% at a depth of 1 m to 13.2% at a 10 m depth. To a depth of 8 m, the bottom fauna was relatively rich in quality. The significant decline in the diversity and, above all, the number of taxa of the macrozoobenthos groups, only at a depth of 10 m were found. In turn, the abundance (density and biomass) of the bottom fauna increased with depth of the site.The analysis of the increase in Oligochaeta abundance with depth suggests that at the level of about 4% of the organic matter content in the bottom sediments, the food conditions are no longer a factor limiting the Oligochaeta occurrence.

Background: The seasonal variations in macroinvertebrate communities in tropical, temperate and subarctic regions have been observed and well documented to date, but similar studies conducted in subtropical rivers at the regional scale are relatively rare. In this paper, the macroinvertebrate communities from the main tributaries in the Three Gorges Reservoir Catchment (TGRC) were investigated as a function of the four seasons to explore the temporal variations in macroinvertebrate communities and further tests the temporal stability of certain metrics that are based on macroinvertebrates under a routine bioassessment framework. Results: The taxa richness reached the highest point in spring, followed by winter, autumn and summer. The taxa Chironomidae, Heptageniidae, Corbiculidae and Baetidae dominated the communities across seasons. The temporal variations in communities were mainly reflected in the changes in taxa proportions between seasons. The percentages of the taxa Heptageniidae and Baetidae were the highest in autumn (normal discharge period) and lowest in summer (high discharge period). The abundance of macroinvertebrates was the lowest in summer, increased in autumn and winter, and then decreased in spring. Natural fluctuations of aquatic ecosystems (temporal effects) resulted in variations that were apparent in macroinvertebrate-based metrics, such as EPT%, Baetidae%, Caenidae%, Ephemerellidae% and Hydropsychidae%. Conclusions:The results of our study demonstrated that the macroinvertebrate communities in the main tributaries of the TGRC varied as a function of seasons. This variation was fundamentally similar to the seasonal patterns in subarctic and temperate streams. Different hydro-morphological characteristics and water quality during the high discharge period (summer), low discharge period (winter) and normal discharge period (spring and autumn) strongly affected the distribution patterns of macroinvertebrate communities. Discharge variation among seasons resulted in seasonal fluctuations in the density of macroinvertebrates. In the TGRC, autumn was the important hatching period for mayflies (Ephemeroptera). The variations in metrics related to macroinvertebrates indicated that temporal effects should not be neglected under a biomonitoring framework in future studies.
