“…Of the indices, TWQI and DSIAR developed from Brazil (Lobo et al, 2015) and Australia (Chessman et al, 2007), respectively, put these streams in a similar environmental condition. This could be due to the effects of ecoregional variations (e.g., climate, geology, land‐use, and anthropogenic activities) playing significant roles on the trophic weight and indicator values of diatom assemblages (Çelekli et al, 2019; Lobo et al, 2015; Salinas‐Camarillo et al, 2021). Concerning that, optima of diatom species for various environmental factors are affected by the fundamental and realized niches (Hutchinson, 1957).…”

Diatom metrics are important tools for evaluating the environmental conditions of streams for the achievement of environmental sustainability. Aim of the present study was to assess the ecological status of De girmendere and Bulaklı streams using diatom indices developed in different ecoregions and to elucidate responses of diatom assemblages to stressors using multivariate approaches. Analysis of similarity percentage indicated a 74% dissimilarity between De girmendere and Bulaklı streams with the most contribution of Encyonopsis minuta, Achnanthidium minutissimum, Achnanthidium druartii, Amphora indistincta, and Gomphonema cuneolus species to this dissimilarity.The first two axes of canonical correspondence analysis exhibited a strong correlation (93.1%) between diatom assemblages and environment variables. Pollution-tolerant species were associated with Bulaklı stream, whereas pollution-sensitive species displayed relatedness to De girmendere stream. Conductivity, salinity, oxidation-reduction potential, total phosphorus (TP), and orthophosphate were the significant effective environmental factors on the spatiotemporal distribution of diatom assemblages. Used diatom indices showed significantly positive and negative correlations with TP gradient. The results of bioassessment exhibited that diatom indices have different scores for the ecological status of the sampling stations. European diatom indices except Trophic Diatom Index and Duero Diatom Index mainly showed similar behavior in the bioassessment of ecological conditions of De girmendere and Bulaklı streams. Among European diatom indices, Trophic Index Turkey was more competitive and could give better results in the bioassessment of streams. Results indicated that ecoregional specific diatom index could be used as a suitable tool to accurately evaluate the surface water quality.

“…Many studies have been carried out to determine the trophic weight and indicator levels of diatom assemblages in different ecoregions (e.g., Rott et al, 1999;Dell'Uomo, 2004;Kelly et al, 2008;Lobo et al 2004Lobo et al , 2015Çelekli et al, 2019b;Salinas-Camarillo et al, 2020). Responses of epilithic diatom assemblages to pollution gradient give crucial information to predict the health of lotic ecosystems (Lobo et al, 2010;Böhm et al, 2013;Heinrich et al, 2015;Castillejo et al, 2018).…”

“…Many indices have been developed based on the trophic weight and indicator values of the diatom species in different ecoregions in the last decades (e.g., Cemagref, 1982;Coste and Ayphassorho, 1991;Rott et al, 1999;Dell'Uomo, 2004;Lobo et al, 2004Lobo et al, , 2015Kelly et al, 2008;Benito et al, 2018;Çelekli et al, 2019b).

“…Occurrences/successions of diatom assemblages in different environmental conditions are deciphered by using multivariate complex statistical analyses to determine their trophic weight and indicator values. The gathered information on state-specific metrics derived from species optima and stressor response model is used in various biological metrics to assess the ecological status of water bodies (e.g., Karr and Chu, 1998;Rott et al, 1999;Dell'Uomo, 2004;Kelly et al 2008;Lobo et al, 2015;Çelekli et al, 2019b;Salinas-Camarillo et al, 2020). Charles et al (2021) reported that the most commonly used metrics are associated with reactive phosphorus, total phosphorus, total nitrogen and nitrate-nitrogen.…”

“…The gray-colored countries have not developed specific diatom indices to assess the ecological status of their surface waters, and some of them are used developed and/or modified indices. However, these countries have different ecoregions including geology, climate, vegetation, wildlife, hydrology, and human activities (Omernik, 1987;Çelekli and Kapı, 2019;Espinosa et al, 2020), which strongly affect the environmental factors on the trophic weight and indicator values of diatom taxa (Lobo et al, 2004(Lobo et al, , 2015Çelekli et al, 2019b;Salinas-Camarillo et al, 2020). Thereby, using foreign diatom indices can lead to erroneous interpretation of water quality.…”

Bioassessment of surface waters is one of the most important approaches to predict the deterioration of ecosystems and achieve environmental sustainability according to the application of the European Water Framework Directive. The present review emphasizes the importance of the bioassessment of freshwater quality especially running waters based on diatom metrics. Nutrient enrichment and hydromorphological alternation driven by human activities are the main factors for the ecological compromise of freshwater ecosystems. Currently, the bioassessment of the ecological condition of inland water bodies is adopted worldwide. Bioassessment is complementary to physico-chemical and hydromorphological data for evaluating the ecological conditions of rivers; however, measuring all the physical and chemical changes is expensive and impractical. Therefore, monitoring biota helps to determine the changes occurring in ecosystems. Thus, diatoms are used as bioindicators to assess environmental conditions of the ecosystems, but their use requires great taxonomic knowledge, otherwise, the results will be biased. Many diatom indices have been developed based on the trophic weight and indicator values of diatoms in different ecoregions in the last decades. This review highlights the importance and advantages of using diatom metrics in the bioassessment of the ecological status of surface waters in the different ecoregions, especially running water. To analyze the complex response of diatom communities to environmental gradients and assess the quality of the ecosystem, multivariate statistical approaches are needed.The challenge here is how to define criteria for classes of water bodies in a biologically meaningful way. For this reason, Biological Condition Gradient is suggested as an appropriate and effective approach to develop trophic criteria based on the relationships between nutrient concentrations and biological indicators of ecological conditions.

In order to determine the ecological status of surface waters of different types in a particular ecoregion, the reference conditions for each type should be identified to compare with observed conditions, as suggested by the Water Framework Directive (WFD). In this study, 36 candidate reference river sites of the Sakarya Basin (Türkiye) were sampled three times in 2018, and the biological assessment of these sites was evaluated using 18 different diatom indices. In addition, nine different environmental variables were also sampled combined with epilithic diatoms. Based on the canonical correspondence analysis (CCA), alkalinity and pH were determined as the most significant environmental variables for diatom assemblages. Among the diatom indices, Biological Diatom Index (IBD), Artois‐Picardie Diatom Index (IDAP), Descy's Index (DES) and Sládeček's Index (SLA) showed significant correlations with alkalinity and pH according to multiple linear regression (MLR) results. IBD index showed the highest response to the pressures and indicated high or good ecological status of the sampling sites. Moreover, rivers with high water quality status have a high correlation with alkalinity, pH and pollution‐sensitive species. On the other hand, good water quality rivers were highly correlated with total phosphorus and intermediate pollution‐sensitive or pollution‐tolerant species. The 13 reference sites established in this study can be used to assess the ecological status by comparison with the same types of river bodies for further studies in the basins of Türkiye.
