“…The diatoms of the studied glacial lakes in the province of Rize form a separate group of high mountain lakes in northern Turkey in terms of taxonomic composition and bioindicators. Consequently, the environmental conditions of high mountains act as selection factors on the flora of diatoms, which was noted earlier [8,9,44,69,71].…”

The benthic diatom assemblages of the glacier Avusor Great Lake and Koçdüzü Great Lake were investigated in August 2019. A total of 71 diatom species belonging to 34 genera were determined in the samples, 49 species from Avusor Great Lake and 37 from Koçdüzü Great Lake. Only 15 diatom species were common to both lakes. Total floristic similarity between the neighbouring lakes was only 21.12%. Genera with the highest number of species were Eunotia (8), Gomphonema (6), Pinnularia (6), Navicula (5) and Aulacoseira (4). The diatom flora of both lakes was formed by cosmopolitan species with a large influence from species in alpine and subalpine area. A comparison of the diatom assemblages of the investigated lakes showed differences in both relative abundance and species present in the individual lakes. Bioindicative analysis showed that the water of Koçdüzü Great Lake is more alkaline and less saturated with organic substances than Avusor Great Lake. In both lakes, the communities are composed of species adapted to living in the benthos of fresh waters of moderate temperature well enriched with oxygen. In both lakes, the water quality was Class 2 with a saprobity index of S = 1.08 in Avusor Great Lake and 0.97 in Koçdüzü Great Lake, but their communities were composed of species with both oligotrophic and mesotrophic status. Statistical comparison of the species composition of studied lakes with other high mountain lakes and the lakes in northern Turkey revealed the role of altitude as the main factor in the formation of diatom floras.

“…We investigated the diatom communities of 14 high mountain lakes and a pond in Kaçkar Mountains National Park and their relationship with environmental factors. The chemistry of the studied lakes characterizes their waters as fresh and soft, slightly saturated with salts, which unites them with the group of high mountain lake Artabel [47], but significantly distinguishes them from the sulfate alkaline lake Great Lota [48].…”

“…In general, the analysis did not reveal a strict relationship to groups of lakes and to altitude, but revealed a noticeable role of species richness as a grouping factor. We supplemented the current analysis with a comparison with the floras of the lakes of the Artabel Park [47] located in The bioindication results of organic pollution obtained from the Sladecek's [41] systems are shown in Figure 5c. Organic pollution indicator groups of Watanabe's [40] method are not presented on the histogram but can be seen in Appendix A Table A3 and demonstrated the same results as Sládeček's method.…”

“…In general, the analysis did not reveal a strict relationship to groups of lakes and to altitude, but revealed a noticeable role of species richness as a grouping factor. We supplemented the current analysis with a comparison with the floras of the lakes of the Artabel Park [47] located in the mountainous region of Turkey, but somewhat to the west, and also included in the analysis two previously studied lakes of the Kaçkar part [15]. Figure 6b shows that the lake communities are grouped according to territorial characteristics, corresponding to two groups of protected areas, while the floras of two previously studied lakes located on the low spurs of the mountains in the Kaçkar Park are included in the western group of lakes of the Artabel Park, emphasizing the high individuality of those studied in this study of 14 lakes and ponds.…”

The altitude of the habitat is one of the important regulators of species survival. Kaçkar Mountains National Park is located in the Eastern Black Sea region of Turkey. This is the first study on the benthic diatom flora of the high mountain lakes in Kaçkar Mountains National Park, which is situated between 2782 and 3075 m a.s.l. A total of 84 diatom species were identified from benthic communities of 15 habitats in summer (19 July, 28 August) and autumn (10 September) months of 2020. The genus Pinnularia (thirteen species) formed the basis of the taxonomic list, followed by Eunotia (five species), Navicula (five species), and Frustulia (four species) genera, respectively. The waters in all the studied lakes were fresh, low-saline, with low-alkaline or circumneutral pH and organically uncontaminated, as evidenced by prevailed bioindicator groups. Statistical methods and comparative floristic results confirm the role of the lake altitude for the diatom species distribution. The species richness of the studied lakes was higher in lakes with lower altitudes. The statistical approach also revealed the potential for an increase in the number of species in high mountain lakes if the study of the diatom flora of the Kachkar Mountains National Park is continued and the species composition of the lakes is replenished. Further studies will be needed to continue exploring this pattern. To protect studied high mountain lakes, their ecological conditions must be constantly monitored in the Kaçkar Mountains National Park.
