“…Some studies were carried out in order to classify the water quality by using diatom indices in Turkey (Kalyoncu et al, 2009;Kıvrak et al, 2012; Morkoyunlu Yüce and Gönülol, 2016; Atıcı et al, 2018). In addition, other studies are also available which evaluate the phytobenthos for each river basin (Demir et al, 2017;Toudjani et al, 2017).…”

In this study, it was aimed to use diatoms as representatives of phytobenthos for estimating the ecological status in Upper Sakarya Basin. Samples were taken seasonally from ten stations from April 2015 to December 2015. Stations 1, 2, 3, 4, 5, 6 and 7 were selected from rivers, stations 8 and 9 were selected from ponds which form Sakarya Springs. Station 10 was located at the outlet of Cifteler Aquaculture and Research Station. Diatoms were identified, counted and 19 diatom indices were calculated. Moreover, water temperature, dissolved oxygen, pH, electrical conductivity were measured in situ, and total nitrogen, orthophosphate and alkalinity were analysed. Finally, ecological status was estimated by evaluating biological, chemical and hydromorphological status according to Water Framework Directive. In total, 96 diatom species were identified from samples and Achnanthidium minutissimum, Cymbella excisa, Craticula subminuscula and Fragilaria brevistriata were the dominant species. Among diatom indices, IDP index which shows a high correlation with total nitrogen was used for the evaluation of the biological status. As a result, ecological status of the station 2 was estimated as high (class I), the status of stations 1, 4, 7, 8, 9 and 10 was estimated as good (class II), and the status of stations 3, 5, 6 was estimated as moderate (class III).

“…In this research, diatom composition and its distribution through the streams, lakes and reservoirs of the basin were studied for the first time in detail, and the diversity was found relatively higher in comparison with different river basins. Solak et al (2018) found 94 taxa from Küçük Menderes River Basin, Çelekli et al (2018) reported 80 taxa from the North Aegean catchment while 148 taxa reported from western Black Sea River catchment (Özer et al, 2018) and Demir et al (2017) observed 64 diatom taxa from Akarçay River Basin. Similarly, 65 diatom taxa were found in Aras River catchment (Çelekli et al, 2019).…”

“…Their prompt response to the environmental changes and their presence throughout the year together with rapid reproduction stages made diatoms an essential tool for monitoring freshwater systems. Studies were conducted in various waterbodies of Turkey to detect the environmental quality of the lakes (Dalkıran et al 2016;Şanal & Demir, 2018) and rivers (Atıcı, 1997;Karacaoğlu & Dalkıran, 2017;Demir et al 2017;Solak et al 2018;Çelekli et al 2019).…”

Diatoms constitute an essential component for biomonitoring studies to determine the ecological quality of waterbodies. In this study, benthic diatoms of Burdur River Basin were investigated as a consequence of a project on river basin management plan. This is the first detailed taxonomical study of diatoms taken from 13 streams, 4 lakes and 6 reservoirs of Burdur River Basin and a total of 223 taxa have been observed. Among genera, Navicula Bory (27) and Nitzschia Hassal (27) were represented with the highest numbers of taxa and followed by Gomphonema Agardh with a total of 22 species. Navicula antonii Lange-Bertalot and Nitzschia palea var. debilis (Kützing) Grunow had the highest relative abundance with 17.1% and 15.5% respectively. As a closed basin, salinity varied greatly from fresh to saline water between the sampling stations and diatom composition contained species with a different tolerance level. Navicula antonii and Nitzschia frustulum (Kützing) Grunow observed in all habitats indicating their euryhaline characters; however Navicula digitoconvergens was only detected in saline Acıgöl lake with a high relative abundance (38%) in autumn. Other two dominant species were Halamphora coffeiformis (Kützing) Levkov and Navicula cincta (Ehrenberg) Ralfs in Acıgöl lake showing their tolerance to high salt content as a brackish species. According to first results, 11 species were new records for Turkish diatom flora. The high biodiversity of diatoms revealed the presence of different habitat characteristics within the basin. These results are an important contribution of Turkish diatom flora and could be useful for monitoring specific areas like Burdur River Basin.

“…Phytoplankton, macrophyte and phytobenthos, benthic invertebrates and fish are the biological quality elements for the classification of ecological status (Anonymous, 2000). There are some studies (Demir et al, 2017;Çelekli et al, 2018;Solak et al, 2018a) for identifying the ecological status of water bodies in Turkey within the scope of the river basin based monitoring studies.…”

Diatoms (important representatives of phytobenthos) are ecologically significant quality elements for rivers and lakes according to the EU Water Framework Directive (2000/60/EC). We aimed to investigate common diatoms of Gediz River Basin within the scope of the studies for preparation of Gediz River Basin Management Plan. Samples were collected from epilithon and epipelon substrates of 17 rivers, 2 lakes (Gölcük and Marmara) and 4 dams (Demirköprü, Küçükler, Buldan, Afşar) from November 2017 to April 2018. The samples were boiled with H 2 O 2 and HCl for removing the organic matter from frustules. Permanent slides were mounted with Naphrax solution. As a result, 28 taxa were found as common diatoms of Gediz River Basin. Many of the taxa were commonly found also in Turkish rivers and lakes. A mphora pediculus (Kützing) Grunow, Navicula reichardtiana Lange-Bertalot, Navicula veneta Kützing, Nitzschia dissipata (Kützing) Rabenhorst and Nitzschia inconspicua Grunow were most common diatoms in sampling points. On the other hand, Navicula erifuga Lange-Bertalot, Navicula reichardtiana Lange-Bertalot and Nitzschia archibaldii Lange-Bertalot were rarely found in Turkish rivers and lakes.
