Özet:

 

Within the scope of the European Union Water Framework Directive, diatom assemblages as biological quality components were used to evaluate the ecological status of 12 surface waters in the Araban-Yavuzeli catchment between October 2013 and October 2014. A total of 75 diatom species were identified during the study period. Amphora ovalis, Denticula elegans, Gomphonema parvulum,Gomphonema  truncatum, and  Navicula  cryptocephala  were  commonly  observed.  The  relationship  between  diatom  assemblages  and  environmental  factors  was  assessed  by  canonical  correspondence  analysis  and  weighted  average  regression.  Dissolved  oxygen,  tem-perature,  nitrate,  biological  oxygen  demand,  lead,  and  copper  played  significant  roles  in  the  distribution  and  composition  of  diatom  assemblages (P < 0.05). The ecological status of the stations in Araban and Yavuzeli was characterized using the trophic index-Turkey (TIT), trophic index (TI), and eutrophication and/or pollution index-diatom (EPI-D) indices. According to the TIT, Ardıl Creek1 had very good ecological conditions and was characterized by the occurrence of pollution-sensitive diatom taxa (e.g., Cymbella affinis, En-cyonema silesiacum, Navicula radiosa), indicated by multivariate analyses. The significant positive correlation of the TIT (P < 0.01, r = 0.789) with logPO4 indicated that TIT may be used as an appropriate diatom metric to assess the ecological status of surface waters in the Araban-Yavuzeli catchment.
