“…Although the commonly used parameters are various basic ecological variables such as water temperature, pH, dissolved oxygen, and nutrients, the excessive increase or decrease of some biological groups depending on these variables are observed. In particular, species composition and the abundance status of diatoms change depending on these variables and are used as an important indicator in determining the trophic status of lakes (13)(14)(15)(16).…”

Objective: In this study carried out in Büyükçekmece Reservoir, the composition, distribution, seasonal changes of epiphytic diatoms that live on the surfaces of plants, and the effects of environmental parameters on these organisms were investigated, and it was aimed to reveal the water quality of the reservoir. Materials and Methods:In order to determine the seasonal changes of epiphytic diatom species in Büyükçekmece Reservoir, water and material samples were collected from five stations in 2019. In the study, water temperature, salinity, conductivity, dissolved oxygen, and pH values, which are among the basic ecological variables, were measured. Epiphytic diatom samples were obtained from Phragmites sp. species. Also, Spearman's rank correlation, Shannon-Weaver diversity index, Cluster (Bray-Curtis and Euclidean Distance), and ordination analysis (DCA and CCA) were applied in the study.Results: 66 epiphytic diatom species were identified in this study, and 36 of these species are new records for the reservoir. Most epiphytic diatom species were obtained in August, and the lowest number was obtained in November. According to the pH values, it was determined that the reservoir is alkaline. In addition, it was determined that the main factors affecting the distribution of epiphytic diatom species in the reservoir are temperature and conductivity, and it was revealed that ecological variables affect species distribution. Conclusion:According to conductivity and DO values, it was determined that the reservoir was of very good and of good quality, and in terms of DO values, the reservoir was mainly oligotrophic. However, station 5 was mesotrophic during the August sampling period, station 4 was mesotrophic, and station 5 was eutrophic in November. Also, Büyükçekmece Reservoir was found in poor and moderate status according to H' classification.

“…Demir et al (2017) reported diatom composition of Lake Eber and the streams in Akarçay River Basin, while analysed the distribution of diatoms in streams and reservoirs of Küçük Menderes River. Benthic diatom community of streams, lakes and reservoirs of Gediz River Basin was also studied by Solak et al (2019). Unlike the other 24 river basins in Turkey, there is no data on benthic diatom composition in the lakes and streams of Burdur River Basin.…”

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.
