    Changing with time of Oligochaeta fauna and some physicochemical features of Corlu stream (Tekirdag)
    (Ege Univ, 2008) Tas, Menekse; Kirgiz, Timur; Arslan, Naime; Camur-Elipek, Belgin; Guher, Huseyin
    This study was performed to determine Oligochaeta fauna and some physicochemical features of Corlu Stream which is the large part of Meric-Ergene River Basin. A total of 9 Oligochaeta species belonging to Tubificidae (4 species) and Naididae (5 species) was recorded in the study during seasonal sampling carried out between 1990 and 1991. Furthermore, some physicochemical parameteres (pH, conductivity, dissolved oxygen, biological and chemical oxygen demands) in the stream which was under the pressure of intensive pollution because of urban and industrial wastes, were measured. To determine the changes in species composition and pollution level one more sampling was made in 2008. Also, some physicochemical features (pH, temperature, dissolved oxygen, nitrite, nitrate, sulphate, phosphate, H2S, Suspended Solid Matter) were measured beside Oligochaeta sampling. It was observed that number of total oligochaeta species was decreased to 4 and the quality of water in the stream was further deteriorated.

    Dynamics of Oligochaeta Fauna in Sazlidere Stream (Edirne, Turkey) with Relation to Environmental Factors
    (Inst Zoology, Bas, 2011) Tas, Menekse; Kirgiz, Timur; Arslan, Naime
    This study was carried out in order to determine Oligochaeta fauna of Sazlidere Stream (Edirne, Turkey) and investigate their distribution between February 2007-December 2007. Samplings were collected in two monthly intervals at four different stations during a year. Oligochaeta individuals were identified on species level and a total of 14 species (Tubifex tubifex (Muller 1774), Limnodrilus hoffmeisteri (Claparede 1862), L. udekemianus (Claparede 1862), Potamothrix hammoniensis (Michaelsen 1901) belonging to subfamily Tubificinae; Chaetogaster diaphanus (Gruithuisen 1828), Stylaria lacustris (Linnaeus 1767), Nais barbata (Muller 1773), N. bretscheri (Michaelsen 1899), N. elinguis (Piguet 1906), Ophidonais serpentina (Muller 1774), Pristina longiseta (Ehrenberg 1938), Slavina appendiculata (D'Ukem 1855), Dero digitata (Muller 1773), Aulophorus furcatus (Muller 1774) belonging to family Naididae and immature tubificidae with hair setae were determined. All the species identified in Sazlidere Stream are new records for the stream. In addition, C. diaphanus, N. barbata, N. bretscheri, O. serpentina, S. appendiculata, P. longiseta are new recods for Oligochaeta fauna of Turkish Thrace. According to Shannon-Weiner diversity index, it was found that Sazlidere Stream has H'= 0.72 diversity values at average. According to Bray-Curtis Cluster analyse results, 1st and 2nd stations have showed the highest similarity in terms of Oligochaeta species and their number and it is observed that this similarity is related to 4th and 3rd station, respectively. Also, water sampling was done to determine some physical-chemical features of surface water (DO, BOD, SO4-2, PO4-3, NO3--N, NO- (2)-N, Mg, Ca, Cl, Chlorophyll-a, suspended solid material, organic matter) and microbiological analysis (total bacteria, total coliform and E. coli). Furthermore, the relationships between oligochaeta species and physical-chemical features was analysed by one way ANOVA test.

    Qualitative and quantitative evaluation of water resources that feed into the National Park Igneada Longoz Forests (Turkish Thrace) by using physico-chemical and biological analyses
    (Univ Autonoma Metropolitana-Iztapalapa, 2015) Camur-Elipek, Belgin; Kirgiz, Timur; Oterler, Burak; Tas, Menekse
    In this study, some physico-chemical and biological features of the water resources that feed three alluvial longose groves (are also known as Longoz) which are important wetlands in the National Park Igneada Longoz Forests including a lot of different ecosystems were investigated. In order to assess the water quality, a total of eight running water resources were sampled within four different seasons and two lakes were sampled at dry and wet seasons in 2008-2009. While some water resources were found to have high quality levels for some physico-chemical findings, the results were also supported by using EPT (Ephemeroptera Plecoptera Trichoptera) index. Furthermore, the cluster analysis, correspondence analysis, and Pearson correlation index were used to determine the relationships between the data. As a result, although a lot of sampled water resources that feed into the National Park area has been found to have good quality level, it was also observed that the area have been under the negative effects of humans. Therefore, at the end of this study, it was also made some suggestions for sustainable usage of this special area.
