  New records from Artabel Lakes nature park (Gümüşhane/Turkey) to the freshwater algal flora of Turkey

  Şahin, Bülent; Akar, Bülent

  Six newly recorded taxa, Chlamydomonas pertusa Chodat, Coenochloris pyrenoidosa Korshikov, Coenocystis tapasteana Komárek, Katagnymene accurata Geitler, Phormidium stagninum Anagnostidis, and Scytonema coactile Montagne ex Bornet & Flahault, were described from epipelic, epilithic, and epiphytic materials of the 17 high mountain lakes and a pond in Artabel Lakes Nature Park. The morphology of all species was examined by light microscopy. In this paper, the morphology, ecology, and distribution of these species are discussed. Photos of the species are also provided.

  New desmid records from high mountain lakes in Artabel Lakes Nature Park, Gümüşhane, Turkey

  Şahin, Bülent; Akar, Bülent

  The algal flora of 17 lakes and 1 pond in the Artabel Lakes Nature Park were investigated during two summer seasons (2013 and 2016). In total, 26 desmid taxa were found and identified as new records for the desmid flora of Turkey based on their morphotaxonomic characteristics and ecological preferences. The taxa identified belong to the genera Actinotaenium (1), Closterium (1), Cosmarium (15), Micrasterias (1), Spondylosium (1), Staurastrum (5), Teilingia (1), and Tetmemorus (1). Morphotaxonomy, ecology, and distribution of each species were discussed in detail.

  Diversity and ecology of benthic algae in Karagöl Lake, Karagöl-Sahara National Park (Şavşat, Artvin, Turkey)

  Akar, Bülent; Şahın, Bülent

  Benthic algal flora of Karagöl Lake, its seasonal variation, and the physical and chemical parameters of the water were studied between October 2008 and September 2010. The algal flora consisted of 112 taxa belonging to the divisions Charophyta (41), Chlorophyta (33), Cyanobacteria (18), Euglenozoa (17), Miozoa (2), and Ochrophyta (1). Six desmid taxa found in this research are new records for the freshwater algal flora of Turkey. The qualitative dominance of benthic taxa typical of slightly alkaline and mesotrophic ecosystems was observed. The qualitative and seasonal variations in epipelic taxa analyzed were dependent on the physicochemical characteristics of the water. Water quality was analyzed on the basis of benthic taxa, which are bioindicators. The physicochemical properties of the water are suitable for the development of a rich algal flora (especially desmids). According to the benthic algal composition and indicator species, it is estimated that Karagöl Lake has mesotrophic lake characteristics. This is the first study of benthic algal flora of Karagöl Lake and marks a significant contribution to the knowledge of Karagöl-Sahara National Park’s aquatic biodiversity.
