“…The FBI values did differ significantly among the reference and tributary stations with downstream stations (P \ 0.05). Based on our results and other studies, the FBI index seems suitable for the assessment of the quality of rivers in Iran (Lydy et al 2000;Shokri et al 2014). The water at the upstream stations of the Shahrood River was reasonably clean, and a suitable habitat for many sensitive macroinvertebrates such as stoneflies and caddisflies (Cole 2002;Storey and Quinn 2011).…”

“…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). Such methodological tools for bioassessment have improved significantly in recent years (Marzin et al 2012;Pace et al 2012;Chang et al 2014;Karaouzas et al 2015).…”

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 spatial and temporal variability of water salinity (Akin et al, 2005;Basset et al, 2013), the high nutrient supply and the strong gradients of both nutrient concentrations (Pérez-Ruzafa et al, 2005;Basset et al, 2013) and dissolved oxygen (Hull et al, 2008;Cozzoli et al, 2013;Shokri et al, 2014) are the main "natural" sources of disturbance. Potential coloniser species, being of freshwater and marine origin (Barnes, 1989;Ciotti et al, 2015), need to cope with these sources of disturbance and particularly with water salinity variability and the related osmoregulation costs, which drive species' standard metabolic rates.…”

Abstract. Standard metabolic rate is a major functional trait with large inter-individual variability in many groups of aquatic species. Here we present results of an experimental study to address variation in standard metabolic rates, over different scales of organisation and environments, within a specific group of aquatic macro-invertebrates (i.e. gammarid amphipods) that represent the primary consumers in detritus food webs. The study was carried out using flow-through microrespirometric techniques on male specimens of three gammarid species from freshwater, transitional water and marine ecosystems. We examined individual metabolic rate variations at three scales: (1) at the individual level, during an 8 h period of daylight; (2) at the within-population level, along body-size and body-condition gradients; (3) at the interspecific level, across species occurring in the field in the three different categories of aquatic ecosystems, from freshwater to marine. We show that standard metabolic rates vary significantly at all three scales examined, with the highest variation observed at the within-population level. Variation in individual standard metabolic rates during the daylight hours was generally low (coefficient of variation, CV<10 %) and unrelated to time. The average within-population CV ranged between 30.0 % and 35.0 %, with body size representing a significant source of overall inter-individual variation in the three species and individual body condition exerting only a marginal influence. In all species, the allometric equations were not as steep as would be expected from the 3∕4 power law, with significant variation in mass-specific metabolic rates among populations. The population from the transitional water ecosystem had the highest mass-specific metabolic rates and the lowest within-population variation. In the gammarid species studied here, body-size-independent variations in standard individual metabolic rates were higher than those explained by allometric body size scaling, and the costs of adaptation to short-term periodic variations in water salinity in the studied ecosystems also seemed to represent a major source of variation.

“…The relatively high variation of water quality parameters related to various types of land use are characteristics that can be used to inform or predict aspects of water quality in rivers that lack data. In this study, physicochemical parameters were significantly different among the stations as the measure in observing water quality that was related to the presence of macroinvertebrates (Mophin-Kani K and Murugesan 2014; Fierro et al 2015;Shokri et al 2014). Water temperature in the upstream of the watershed was low due to the closure of the water body by the forest compared to the middle and downstream part which was already opened, especially at the edge of the river (Rezende et al 2016).…”

Abstract. Kahirun, Sabaruddin L, Mukhtar, Kilowasid LOMH. 2019. Evaluation of land use impact on river water quality using macroinvertebrates as bioindicator in Lahumoko Watershed, Buton Island, Indonesia. Biodiversitas 20: 1658-1670. The Lahumoko Watershed, a small watershed, that empties into the sea is sensitive to water quality changes due to land use changes by humans. Uncontrolled land use changes can threaten the sustainability of the river ecological functions of the watershed. It is important to examine the comparison of river water quality in locations that represent land uses. So, the objectives of this study were to reveal the impact of land use on biological water quality in rivers and to analyze the relationship between macroinvertebrates communities with parameters of biodiversity and physicochemical at the observation locations that represented land use. Biological samplings were done using a hand net with a hole size of 0.5 mm mesh, at five stations, each with three replications, with a length of 30 m of each replication, 60 minutes per station. The results of the study showed that individual abundance, family biotic index and diversity index parameters indicated that the water quality was quite good in the upstream watershed (LM1, LM2, and LM3 stations) and somewhat worse in the middle (LM4 station) and downstream of the watershed (LM5 station). The Spearman's correlation, Dendrogram, and Canonical Correspondent Analysis (CCA) showed that there were similarities among LM1, LM2 and LM3 stations, and also between LM4 and LM5 stations. Physicochemical parameters, especially the velocity and flow rate of the river flow had significant correlation with individual richness and density.
