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

Abstract

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 R 2 = 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.

Microalgae Indicators of Charophyte Habitats of South and Southeast Kazakhstan

“…In densely populated areas, communities containing charophytes attract the attention of researchers. Therefore, in Turkey, the dynamics and diversity of the cohabitants of charophytes and microalgae in the Artabel Lakes Nature Park and high mountain lakes in Rize were described [68,69], and the influence of hydrology on the distribution of their diversity was revealed. Lakes Great Lota and Isikli, inhabited by charophytes, were studied in relation to the dynamics of the diversity of associated microalgae communities [7,70,71].…”

Role of Altitude in Formation of Diatom Diversity of High Mountain Protected Glacier Lakes in the Kaçkar Mountains National Park, Rize, Turkey

“…It has been previously found [35,41] that the Willis curve can be a criterion for the fullness of a species list in well-studied algal floras in Eurasia. Therefore, we can carry out floristic, taxonomic, and ecological analysis for the diatom flora in AGL and KGL and compare it to other high mountain lake floras in this region where the Willis proportion also closely follows the hyperbolic shape [8,[42][43][44][45][46]. When the diatom communities of the investigated lakes were compared, differences were observed in species composition and relative abundance of each lake.…”
