New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkey, Part IV: Ochrophyta

Öz

Turkish 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 Turkey.
