“…The TSI index results showed that Lake Bafa was from the limiting mesotrophic to slightly eutrophic. Sömek and Ustaoğlu (2016) stated that oligotrophic and mesotrophic indicatör species are found together in the phytoplankton composition of Saklıgöl, Karagöl, Gökçeova Pond and Kartal Lake, and considering the TSI values, the productivity status of the studied lakes is still oligotrophic but has a transition trend towards mesotrophic state. According to Akçaalan et al (2007), in the research carried out in Sapanca Lake, which is an oligo-mesotrophic lake, diatom was reported to be predominantly found during the research period.…”

“…After the classification of collected samples, Cyanophyceae (11.2%), Bacillariophyceae (49.2%), Chlorophyceae (23.8%), Xanthophyceae (1.5%), Euglenophyceae (11.2%) and Dinophyceae (3.1%) classis were determined. Cyanobacteria members were commonly detected in eutrophic lakes in our country (Cirik-Altındağ, 1982;Sömek and Balık, 2009) and they had excessive growth in eutrophic lakes rich in nutrients in summer months (Vaitomaa, 2006). In this study, a few taxa (Cylindrospermopsis raciborskii, Lyngbya sp.…”

Phytoplankton groups are one of the major quality element to be used in the evaluation of the trophic and ecological state of freshwater ecosystems according to the EU Water Framework Directive. This research was made to assess the trophic and ecological status of Lake Bafa in Turkey, on the basis of phytoplankton communities. Büyük Menderes River is one of the most important factor that carries pollutants to Lake Bafa. The eight sampling station were assigned to evaluate the ecological and trophic state of the lake. Phytoplankton species were collected monthly for 2 years study period. Most commonly used phtoplankton indices Q index and Carlson's Trophic State Index (TSI), and different versions of diversity indices were used to estimate trophic and ecological state of the lake. Similarities between the sampling stations were clustured by using the unweighted pair group method using arithmetic average (UPGMA), based on phytoplankton communities. Correlations between the applied indices were determined by using Pearson Correlation. After the identification of collected phytoplanktons, total of 63 taxa which belong to classis of Cyanophyceae (11.2%), Bacillariophyceae (49.2%), Chlorophyceae (23.8%), Xanthophyceae (1.5%), Euglenophyceae (11.2%) and Dinophyceae (3.1%) were detected. The 1 st and 2 nd stations were the most similar stations to each other (88%) according to phytoplankton communities. Secchi disc depth (SD) and TP played an important role in the distribution of phytoplankton species in Lake Bafa. The highest significant positive correlation was determined between Q and TSI (r = 0.987, p˂0.01). Considering the TDI values in the phytoplankton composition of the lake, it can be said that although the productivity status of the studied lake is still "mesotrophic", it has a tendency towards "eutrophic" state. According to the Q values, the first five stations reflect the moderate ecological state, while the 6 th , 7 th and 8 th stations represent the poor ecological state.

“…(Dullinger et al, 2012). For this reason, these ecosystems are represented by relatively low numbers of endemic or adapted species to extreme environmental conditions (Galas, 2004;Krno et al, 2006;Sömek & Ustaoğlu, 2016). In this respect, these lakes are reference points in testing the effects of environmental degradation on the ecosystem (Galas, 2004;Taşdemir & Ustaoğlu, 2016).…”

This study was carried out in July and August 2019 as a preliminary study to determine the benthic macroinvertebrate fauna of Karagöl, Çömçe and Yıldız Lakes, which are high-altitude lakes in the Aladağlar mountains. As a result of the examination of the collected macrobenthic fauna, seven species belonging to three families from three orders (Diptera, Coleoptera and Trichoptera) in Karagöl Lake, four species belonging to three families from two orders (Diptera, Haplotaxida) in Çömçe Lake, and five species belonging to three families from three orders (Diptera, Trichoptera, Haplotaxida) in Yıldız Lake were determined. The taxa detected is a new record for the studied lakes. Shannon-Weaver diversity (H) and Shannon-Evenness density (EH) indices were applied in order to determine the species richness of the lakes and the density relationships among the species, respectively. Accordingly, the highest diversity was observed in Çömçe Lake with a value of 1.18, followed by Karagöl Lake, and Yıldız Lake with values of 0.87 and 0.83, respectively. While the most balanced distribution was observed in Çömçe Lake with a value of 0.81, this was followed by Yıldız Lake and Karagöl Lake, with values of 0.46 and 0.34, respectively. In order to determine the similarities between the stations according to the distribution of the detected taxa, a two-way clustering analysis based on the Bray-Curtis similarity index was applied. Accordingly, while the highest similarity was calculated between Karagöl Lake and Yıldız Lake, it was determined that there was no similarity between Yıldız Lake and Çömçe Lake.
