Summary

<p>Troughs are one of the main components of villages in Turkey. They are constructed by converting springs or underground<br /> waters. Until now, there has been no extensive study investigating the composition and diversity of trough zooplankton species. In order<br /> to contribute knowledge on the zooplanktons in troughs, 142 troughs were randomly sampled from 17 districts in Ankara Province<br /> between 22 June and 3 July 2011. A total of 18 zooplanktons including 11 Copepoda and 7 Cladocera species were determined. Twelve<br /> of the 18 (Paracyclops chiltoni, Paracylops fimbriatus, Paracyclops imminutus, Tropocyclops prasinus, Diacyclops bisetosus, Acanthocyclops<br /> vernalis, Canthocamptus staphylinus, Attheyella crassa, Bryocamptus minutus, Macrothrix hirsuticornis, Oxyurella tenuicaudis, Moina<br /> macrocopa) are new records for Ankara. Paracyclops imminutus was reported for the third time in Turkey in the last 50 years. UPGMA<br /> illustrated 4 main clustering groups of species corresponding to some of their ecological characteristics. Poisson distribution analysis<br /> showed almost random distribution of species among the troughs (s2/&mu; = 1.04). With their cosmopolitan characteristics, 3 species<br /> (M. hirsuticornis, E. serrulatus, and C. sphaericus) are the most common species. Their ecological tolerance and optimum values were<br /> higher than the mean tolerances for different environmental variables. The results show that troughs may provide suitable conditions<br /> for zooplankton species.</p>
