TAILIEUCHUNG - Species composition and distribution of centric diatoms from Türkmen Mountain (Sakarya River Basin/Turkey)

Diatoms are used for monitoring the environmental conditions of water. We have little information about centric diatoms in Turkish freshwaters. A total of 50 samples were collected from some springs and small streams of Türkmen Mountain. | Turkish Journal of Botany Turk J Bot (2013) 37: 589-596 © TÜBİTAK doi: Research Article Species composition and distribution of centric diatoms from Türkmen Mountain (Sakarya River Basin/Turkey) 1,2, 3 Cüneyd Nadir SOLAK *, Maxim KULIKOVSKIY Department of Biology, Arts and Science Faculty, Dumlupınar University, Kütahya 43100, Turkey 2 Department of Palaeoceanology, Institute of Marine Sciences, University of Szczecin, Szczecin 70-383, Poland 3 Department of Algology, I.

We have little information about centric diatoms in Turkish freshwaters. A total of 50 samples were collected from some springs and small streams of Türkmen Mountain. As a result, 7 species [Cyclotella meneghiniana Kützing, C. ocellata Pantocsek, Cyclostephanos dubius (Fricke) Round, Handmannia balatonis (Pantocsek) Kulikovskiy & Solak comb. nov., Melosira varians Agardh, Stephanodiscus hantzschii Grunow, and S. minutulus (Kützing) Cleve & Möller] were identified, and we also suggest in this study that a new combination for Cyclotella balatonis Pantocsek should be Handmannia balatonis comb. nov. and for C. praetermissa Lund should be Handmannia praetermissa comb. nov. Key words: Centric diatoms, Handmannia, Türkmen Mountain, Turkey 1. Introduction Diatoms are used for monitoring the environmental conditions of water. They indicate water quality level of many aquatic environments, and so they have been used in a number of countries in Europe as indicators of river pollution (Whitton et al., 1991). The diatom communities in similar climatic conditions were studied with respect to the seasonal influences of environmental factors of the systems .
