This research paper gives insight into the physico-chemical characteristics of the Rana stream located in the Mandi district of Himachal Pradesh, India, with a particular emphasis on the diversity of diatoms. During the course of this study, eight genera of phytoplankton were identified. Statistical analysis using Pearson correlation unveiled significant associations between the physicochemical parameters and the different groups of diatoms. To assess the diversity of phytoplankton within the stream, several diversity indices were employed. Highest diversity was observed during the month of February. Furthermore, the calculation of water quality indices for the Rana stream yielded values falling within the range of 47.34 to 59.01. This range signifies that the water quality within the Rana stream can be categorized according to the Water Quality Index (WQI) scale, spanning from “good” to “poor.” It is worth noting that the presence of a diverse assembly of pollution-tolerant diatoms such asFragilaria, Navicula, Gomphonema, andCymbella, particularly during the month of March, which coincided with the period of the poorest water quality, is indicative of the eutrophic nature of the stream.

“…The Sakarya River originates from the Çifteler Sakarbaşı springs at an elevation of 800 m a.s.l. south of Eskişehir city centre; it is mainly fed by the Porsuk, Ankara, Karasu, Göksu, Çarksuyu and Mudurnu streams and flows into the Black Sea in the Karasu district of Sakarya province (Atıcı & Yıldız, 1996; Selki, 2008). The Köroğlu and Sündiken mountains are located in the north, the İdris Mountain, the Elmadağ Mountain and the Haymana Plateau in the east, the Emir Mountain, the Murat Mountain, the Bayat and Cihanbeyli Plateaus in the south and the Domaniç and Uludağ mountains in the west of the basin.…”

Using diatom indices to estimate the ecological status of minimally disturbed rivers of the Sakarya River Basin (Türkiye)

et al. 2023

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.

A total of 15 Navicula taxa were recorded in epilithic communities occurring in seven rivers of Serbia, all of which are new to the diatom flora of Serbia. The most interesting of them are N. splendicula and N. moskalii. When observing N. splendicula specimens under SEM, we noticed a characteristic silicate tongue in the center of raphe ends, which had not been previously reported in the available literature. The insufficiently researched distribution of N. moskalii and scarce autecological information on the taxon prompted us to provide new details about the species in this study. These findings clearly indicate the need for further comprehensive research that would provide new information on rare taxa.
