    Although planktonic algae are a basic component of freshwater ecosystems, studies on their diversity and species distribution are still not in satisfactory numbers. This study aims to contribute to Turkish freshwater algal flora particularly with the new records reported. A total of 158 Charophyta taxa were determined in the study conducted from 2017 to 2019 in 25 river basins of Turkey. In this study, while the highest Charophyta taxon was found in Sakarya and Batı Akdeniz basins with 50 and 42 taxa, respectively, Burdur basin was the only basin where we did not find the Charophyta species. The highest Charophyta diversity was observed in Girdev Lake (Batı Akdeniz basin) and Işık Dağı Karagöl Lake (Sakarya basin) among the lakes of Turkey’s 25 river basins. Thirty-one of these Charophyta taxa represent new records for the freshwater algal flora of Turkey. Of these, 13 species are commonly distributed, while 18 species have rare distribution areas. Morphology, ecology, and distribution of each taxon were also discussed in details.

    New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkiye, Part I: Bacillariophyta

    The 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.

    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, Hasim
    Turkish 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.
