    Cohabitant charophyte algal flora and its ecology in high-mountain lakes of the Artabel Lakes Nature Park (Gumushane, Turkey)

    Şahin, Bülent; Akar, Bülent; Barinova, Sophia

    The composition of charophyte taxa and their habitat preferences in water bodies of the Artabel Lakes Nature Park were investigated on 15 August 2013 and 13 August 2016. A total of 73 taxa belonging to Conjugatophyceae (Zygnematophyceae) and Klebsormidiophyceae were recorded. The genera Cosmarium (37), Staurastrum (10) and Closterium (7) were most abundant. The partly unexpected presence of certain desmid taxa, i.e., taxa characteristic of eutrophic water, was recorded. Filamentous charophytes were represented by three taxa. The Willis curve for the distribution of species to genera had a trend line of R2 = 0.9123. Bioindication, statistical methods and comparative floristic results show that water in all of the studied lakes was fresh, of low-conductivity, circum-neutral and with little organic pollution. Four groups of lakes were identified as a result of statistical comparison of their environmental and biological variables. Bioindication results can be used as references for future monitoring of the lakes in protection of the species found in the Artabel Lakes Nature Park and can also be included in the National Water Quality Standard System of Turkey.

    Non-Diatom Algae of the High Mountain Protected Lakes in the Artabel Lakes Nature Park, Gümüşhane, Turkey

    Şahin, Bülent; Akar, Bülent; Barinova, Sophia

    For the first time, we studied 18 lakes of the Artabel Lakes Nature Park and revealed 154 species of non-diatoms algae from four taxonomic Divisions. Charophyta (73 taxa) prevails in the flora and mainly represented by the genus Cosmarium (37). Cyanobacteria (42), Chlorophyta (30) and Eunlenozoa (9) are also present. New records for the Turkish algae flora are represented by 31 taxa, most of which belong to Cosmarium (15) and Staurastrum (5). Rare species from benthic cyanobacteria were revealed in communities of the Artabel Lake. Statistical methods revealed a high individuality of the algae communities and divided it into two major group: Acambol–Yıldız, and Beş–Artabel, which belong to different River Basins. The altitude of the lakes appears to be the major environmental variable that controls the non-diatom algal diversity. Bioindication characterized the water of studied lakes as temperate by temperature, middle saturated with oxygen, neutral to low acidic pH, low saline, Class 2–3 of Water Quality and mesotrophic.

    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.
