    Odonata fauna of Alara and Karpuz streams and their relations with physico-chemical variables
    (Parlar Scientific Publications, 2018) Kalyoncu, Hasan; Salur, Ali
    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.

    The use of BMWP and ASPT indices for evaluation of water quality according to macroinvertebrates in Kucuk Menderes River (Turkey)
    (De Gruyter Open Ltd, 2016) Arslan, Naime; Salur, Ali; Kalyoncu, Hasan; Mercan, Deniz; Barişik, Burcu; Odabaşı, Deniz A.
    This study was carried out in the Kucuk Menderes River basin in order to determine the water quality and investigate the environmental quality and the applicability of both the Biological Monitoring Working Party (BMWP) and Average Score Per Taxon (ASPT). Monitoring took place in May, July and September 2014 at 10 stations (7 rivers and 3 lakes) according to the method of Intercalibration Common Metrics. Some metrics (BMWP, ASPT, Family Biotic Index, Simpson Diversity Index, Shannon-Wiener Diversity Index, Margalef Diversity Index, dominance, frequency and existence of sensitive species) were calculated. In total, 69 taxa comprising 5,814 individuals were detected. The taxa having the highest frequency rate were Limnodrilus hoffmeisteri (70%), Chironomus (Camptochironomus) tentans (70%), Psammoryctides albicola (60%), Physella acuta (60%), Nais elinguis (60%) and Stylaria lacustris (50%), which are alpha mesosaprobic and polysaprobic species, respectively. The presence and high dominance and frequency rate of these species have indicated basin pollution. Positive indicator species for water quality are Gomphus schneideri, Trithemis annulata, Lindenia tetraphylla, Orthetrum cancellatum, Hydropsyche angustipennis, Cricotopus (Cricotopus) fuscus and Cricotopus (Cricotopus) annulator, while negative indicator species are Culex pipiens, Chironomus (Camptoch.) tentans, Chironomus thummi, Stylaria lacustris and Eristalis tenax. Habitat quality of the Kucuk Menderes River basin was not high (it was found to be heavily polluted/polluted/slightly polluted according to the physicochemical data, BMWP and ASPT) due to physical habitat degradation, urban waste waters, touristic, seasonal dwelling and agricultural activities. © 2016 Institute of Zoology, Slovak Academy of Sciences.
