Odonata fauna of Alara and Karpuz streams and their relations with physico-chemical variables

Abstract

In this study, it was aimed to determine the Odonata fauna of Karpuz and Alara streams and prevail their relationships with physiochemical parameters. For this purpose, a total of twenty sampling points were chosen on streams. As a result of field studies nine species of Odonata were recorded in Alara Stream and four Odonata species were recorded in Karpuz Stream. Caliaeshna microstigma, Epallage fatime, Ischnura elegans and Platycnemis pennipes were described as common species in both streams. Calopteryx virgo festiva, Ischnura elegans, Platycnemis pennipes were sampled only in 10 th sampling point while Onychogomphusforcipatus albotialis and Epallage fatime were sampled in all other sampling points. Gomphus schneideri was recorded only at 7 th sampling point. Epallage fatime was found in all sampling points except 10 th sampling point. Caliaeshna microstigma, Ischnura elegans and Platycnemis pennipes were found in 10 th station. Epallage fatime was determined dominant taxon in Karpuz Stream while Caliaeshna microstigma and Onychogomphus forcipatus were dominant in Alara Stream. In both streams water quality of first 8 sampling points were included in quality level I while 9 th sampling point was included in quality level I-II and 10 th sampling point in quality level II according to physical-chemical variables. 9 th and 10 th sampling point of each stream were affected by pollutants while the others were less affected. © by PSP.
