New desmid records from Kaçkar Mountains National Park (Rize/Turkey)

Abstract

The periphytic algal samples were taken from 14 lakes and one pond in the Kaçkar Mountains National Park in 2020. The samples were observed under light microscope for their morphometric characteristics based identification. At the end of the research, 78 taxa belonging to the Charophyta division were identified. 7 of them, which are Closterium jenneri var. curvatissimum (West & G.S.West) A.J.Brook & D.B.Williamson, Cosmarium margaritiferum f. regularis (Nordstedt) West & G.S.West, Euastrum ansatum var. concavum Willi Krieger, E. verrucosum var. coarctatum Delponte, E. verrucosum var. planctonicum West & G.S.West, Staurastrum capitulum Brébisson and S. sexcostatum Brébisson ex Ralfs, were determined as new records for the desmid flora of Turkey. In this paper, morphotaxonomy, ecology, and distribution of each species are discussed in detail and it has been also recorded the geographic distribution of desmid species in Turkey.
