Abstract

Diatoms (important representatives of phytobenthos) are ecologically
important quality elements for rivers and lakes according to Water Framework
Directive (2000/60/EC). In this study, it was aimed to investigate common
diatoms of Gediz River Basin within the scope of the preparation of Gediz River
Basin management plan studies. Samples were collected from epilithon and
epipelon substrates of 17 rivers, 2 lakes (Gölcük and Marmara) and 4 dams (Demirköprü,
Küçükler, Buldan, Afşar) in November 2017 and April 2018. Samples were boiled
with H₂O₂ and HCl for removing the organic matter from
frustules. Permanent slides mounted with Naphrax solution. As a result, 20 taxa
were found as common diatoms in Gediz River Basin. Among the taxa, many of them
were commonly found also in Turkish rivers and lakes. Amphora pediculus (Kützing) Grunow, Navicula
reichardtiana Lange-Bertalot, Navicula
veneta Kützing, Nitzschia
dissipata (Kützing) Rabenhorst
and Nitzschia inconspicua Grunow were
most common diatoms in sampling points. However, Navicula erifuga Lange-Bertalot,
Navicula reichardtiana Lange-Bertalot
and Nitzschia archibaldii Lange-Bertalot
were rarely found in Turkish rivers and lakes.
