Öğe New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkey, Part III: Miozoa, Haptophyta(2021) Sevindik, Tuğba Ongun; Soylu, Elif Neyran; Demir, Ayşe Nilsun; Çelekli, Abuzer; Sömek, Haşim; Öterler, Burak; Coşkun, TolgaTurkish lakes have different morphometry and hydrology as a result of different climate types and noticeable altitude differences, which provide different habitats for algal diversity. In the last 40 years, the total number of algae taxa in the flora of Turkey has increased due to the studies on phytoplankton taxonomy and ecology. This study aims to describe new planktonic algal taxa for the Turkish freshwater algal flora. A total of 63 Miozoa and 2 Haptophyta taxa were determined in the project conducted from 2017 to 2019 in lakes of 25 river basins of Turkey. Our study was done as a part of the Project, namely “Establishment of Reference Monitoring Network in Turkey”, financially and technically supported by the Ministry of Agriculture and Forestry, Directorate General for Water Management. In each lake, phytoplankton was sampled with water samplers from three depths (surface, middle, and bottom) of the euphotic zone, and then the water samples taken from these three depths were mixed for obtaining subsamples. Plankton net with a pore diameter of 50 µm was also used for sampling. Identification of the algal taxa was performed with various compound and inverted microscopes in many laboratories. During this study, 26 Miozoa and 2 Haptophyta taxa were found as new records for the freshwater algal flora of Turkey.Öğe New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkey, Part IV: Ochrophyta(2021) Demir, Ayşe Nilsun; Öterler, Burak; Sömek, Haşim; Sevindik, Tuğba Ongun; Soylu, Elif Neyran; Karaaslan, Yakup; Çetin, TolgaTurkish lakes have different morphometric and hydrological features as a result of different climates and noticeable altitude differences in Turkey that are necessary conditions to occur different habitats for algal diversity. The total number of algae taxa in the flora of Turkey has increased due to the growing number of studies on phytoplankton taxonomy and ecology in the last 40 years. This study aims to describe new planktonic algal taxa for the Turkish freshwater algal flora. A total of 56 Ochrophyta taxa were determined in this study, conducted from 2017 to 2019 in lakes lies in 25 river basins of Turkey. In 275 lakes, samples of phytoplankton were collected with water samplers from three depths (surface, middle, and bottom) of the euphotic zone, and then subsamples were obtained by mixing the water samples taken from these three depths. The plankton net with a pore diameter of 50 µm was also used for collecting samples of phytoplankton. The algal taxa was identified by using different types of compound and inverted microscopes in many laboratories. 30 Ochrophyta taxa of which were determined in this study, were reported as a new record for the first time for the freshwater algal flora of TurkeyÖğe New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkey, Part V: Cryptophyta(2021) Soylu, Elif Neyran; Demir, Ayşe Nilsun; Coşkun, Tolga; Solak, Cüneyd Nadir; Çelekli, Abuzer; Sömek, Haşim; Öterler, BurakThere is an increasing number of taxonomic and ecologic studies on phytoplankton, one of the biological quality elements according to the EU Water Framework Directive, in Turkey day by day. This study was carried on from 2017 to 2019 in 275 lakes lies in 25 river basins of Turkey with the aim of examining the taxonomy and biological diversity of the Cryptophyta group. It was the fourth part of the Project, entitled “Establishment of Reference Monitoring Network in Turkey”, financially and technically supported by the Ministry of Agriculture and Forestry, Directorate General for Water Management. In each lake, phytoplankton was sampled with water samplers from three depths (surface, middle, and bottom) of the euphotic zone, and then the water samples taken from these three depths were mixed for obtaining subsamples. The algal taxa was identified by using different light and inverted microscopes in many laboratories. A total of 24 Cryptophyta taxa were identified in the study. 9 of the identified Cryptophya taxa were presented as new records for the freshwater algal flora of TurkeyÖğe New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkiye, Part I: Bacillariophyta(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2023) Coskun, Tolga; Celekli, Abuzer; Solak, Cuneyt Nadir; Sevindik, Tugba Ongun; Demir, Nilsun; Soylu, Elif Neyran; Somek, HasimThe present study aimed to contribute to the algal flora of Turkiye by Bacillariophyta (diatom) as new records for the Turkish freshwater. Phytobenthos and phytoplankton were sampled three times (spring, summer, and autumn) a year between 2017 and 2019. Samples of the phytoplankton were collected with a water sampler from three depths, and samples of diatoms were obtained as epiphytic in the littoral zone of the lakes. However, if macrophytes were absent, epilithic or epipelic diatoms were sampled in lakes. Also, samples of phytobenthos were preferred as epilithic in rivers. However, if stones were absent, epiphytic or epipelic diatoms were sampled. During the studied period, a total of 895 diatom taxa were determined as planktonic (378 taxa) and benthic (860 taxa) in lakes and rivers of 25 river basins of Turkiye, and a total of 39 new records were identified. The highest diatom taxa were determined in the Firat-Dicle, Konya, Antalya, and Buyuk Menderes basins with 11, 11, 10, and 6 taxa, respectively. On the other hand, new records were not detected in 10 basins.Öğe New Records for The Turkish Freshwater Algal Flora in Twenty-five River Basins of Turkey, Part II: Chlorophyta, Cyanobacteria, Euglenozoa(Central Fisheries Research Inst, 2022) Maraslioglu, Faruk; Oterler, Burak; Sevindik, Tugba Ongun; Soylu, Elif Neyran; Demir, Nilsun; Celekli, Abuzer; Somek, HasimTurkish lakes which have different morphometry and hydrology, have a great potential that supports distinct algal diversity as a result of different climate types and geographical variation (latitudinal, longitudinal, and altitudinal gradients). However, the algal flora of Turkey has not been completed, and the number of new taxa has increased due to new studies in Turkey. This study aims to describe new planktonic algal taxa for the Turkish freshwater algal flora. A total of 330 Chlorophyta, 164 Cyanobacteria and 187 Euglenozoa taxa were determined in a study conducted from 2017 to 2019 in 275 lakes of 25 river basins of Turkey. During this study, 116 Chlorophyta, 41 Cyanobacteria, and 81 Euglenozoa were found new records for the freshwater algal flora of Turkey.
