- Abstract
Epipelic diatoms and some physico-chemical features of Torture streams were studied in the samples collected montly from four sampling-stations during June 2005-February 2006. A total of 113 taxa of epipelic diatom were determined. According to cluster analysis, dominant diatom species constituted two groups (eutrophic and polluted). Cocconeis placentula vat. euglypta in I. group (eutrophic) and Nitzschia palea ve Navicula cryptocephala in II.group (polluted) were established to be the most explicit dominant species. N. palea and N. cryptocephaIa were correlated positively with nutrient concentrations. Significant correlation was found between C. placentula var. euglypta and conductuvity. The composition of dominant taxa and results of chemical analysis indicated that Tortum streams was organically polluted.
