Benthic Diatom Composition of Iztuzu Coastal Lake, Dalyan (Aegean Sea, Turkey)

Abstract

Coastal lakes are shallow lakes that have variable characteristics through fluctuations and marinewinds. In this study, benthic diatom composition in the coastal lake of Iztuzu, Dalyan of Muğla wasinvestigated from the material collected in 2011 and 2015. Little research has been done on coastal lakes and lagoon diatom flora in Turkey; this study contributes a total of 49 taxa identified tospecies level and 9 of the taxa for the first time recorded for diatom flora of Turkey. The mostabundant taxa were; Cocconeis placentula Ehrenberg, Diploneis bombus (Ehrenberg) Ehrenberg,Mastogloia sp. and Chamaepinnularia alexandrowiczii Witkowski, Lange-Bertalot and Metzeltin.The results reveal a habitat-specific flora for Iztuzu Lake and give an aspect of understanding themarine-brackish distribution of diatoms in coastal lakes and lagoons. The results extend theknowledge of marine and brackish diatoms in Turkey and could provide data for similar lagoonand lakes which are under protection.
