Öğe ABUNDANCE AND DIVERSITY OF ZOOPLANKTON IN THE MERIC RIVER (TURKEY)(Parlar Scientific Publications (P S P), 2016) Guher, HuseyinThis study aims to determine the diversity and abundance of zooplankton in Merig River that forming a border between Greece and Turkey is the biggest river (539 km in length) in Balkan Peninsula. Samples were collected in monthly intervals between March 2011 and February 2012 from eight different stations using a Hensen type plankton net with a mesh size of 55 nm. The samples were preserved in 4% formalin. Qualitative and quantitative analyses revealed the presence of 85 taxa in total, including 52 taxa of Rotifera, 21 taxa of Cladocera and 12 taxa of Copepoda. Rotifera presented the highest relative abundance (87 %) and density (739,13 ind./m(3)) followed by Copepoda (density of 85,48 ind./m(3) and abundance of 10 %) and Cladocera (density of 29,16 ind./m(3) and abundance of 3 %). Thirteen environmental parameters were measured to determine the physicochemical of the river.Öğe Analysis of Benthic Macroinvertebrates in Relation to Environmental Variables of Lake Gala, a National Park of Turkey(Central Fisheries Research Inst, 2010) Camur-Elipek, Belgin; Arslan, Naime; Kirgiz, Timur; Oterler, Burak; Guher, Huseyin; Ozkan, NurcanIn order to determine the relationships between the dynamics of benthic macroinvertebrates (both species number and individual number) and environmental variables, sampling was made at four different stations at monthly intervals during a year between March 2004 and January 2005 of Lake Gala which is a part of an important wetland and a national park in European part of Turkey (Enez/Edirne). Altogether, a total of 49 zoobenthic taxa which were grouped as Oligochaeta, Chironomidae, and Varia, comprised of 1,628 individuals in per m(2) at average were recognised in the sampling stations of the Lake. The present study showed that larval chironomids comprising 57% abundance of the total specimens are the biggest part of benthic macroinvertebrates. It is followed by oligochaetes and the group varia comprising 34% and 9% abundance, respectively. Also, it was seen changing that the composition of zoobenthic group dominancy in the Lake as time passes. Furthermore, according to Shannon-Wcaner index, species diversity for zoobenthic macroinvertebrate fauna of the lake was found as H'=1.21 at average. Also, similarities of the sampling stations and months, both the dynamics of benthic macroinvertebrates and physicochemical features were evaluated by using Bray-Curtis similarity index. According to Spearman correlation index, relationship between the number of individuals and some physicochemical variables such as temperature, turbidity (light permeability), and depth of the lake was determined statistically significant.Öğe 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, HuseyinThis 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.Öğe The Chironomidae (Diptera) fauna of Kirklareli Province(Tubitak Scientific & Technological Research Council Turkey, 2017) Aydin, Gazel Burcu; Guher, HuseyinLarval and adult material collected from July 2012 to July 2013 and previously collected larval material were evaluated taxonomically to determine the Chironomidae (Diptera) fauna of Kirklareli Province. Accordingly, a total of 64 species belonging to the subfamilies Tanypodinae, Prodiamesinae, Orthocladinae, and Chironominae of the family Chironomidae were determined, of which Camptocladius stercorarius (De Geer, 1776), Corynoneura sp., Paratanytarsus sp., Ablabesmyia (Ablabesmyia) phatta (Eggert, 1863), Chironomus semireductus (Lenz, 1924), Einfeldia carbonaria (Meigen, 1804), Metriocnemus (Metriocnemus) fuscipes (Meigen, 1818), Rheocricotopus (Rheocricotopus) fuscipes (Kieffer, 1909), and Stictochironomus sp. were determined as new records for Kirklareli Province, Acricotopus lucens (Zetterstedt, 1850), Brillia flavifrons (Johannsen, 1905); Cladopelma virescens (Meigen, 1818), Demicryptochironomus sp., and Harnischia curtilamellata (Malloch, 1915) for Turkish Thrace; and Paratanytarsus laetipes (Zetterstedt, 1850) for Turkish Chironomidae fauna.Öğe DETERMINING OF WATER QUALITY BY USING MULTIVARIATE ANALYSIS TECHNIQUES IN A DRINKING/USING WATER RESERVOIR IN TURKEY(Parlar Scientific Publications (P S P), 2017) Elipek, Belgin Camur; Guher, Huseyin; Oterler, Burak; Divrik, Menekse Tas; Mimiroglu, Pinar Altinolukl This study has been carried out to assess the water quality of a drinking/using water reservoir in Turkey by using the different multivariate statistical techniques (Bray-Curtis cluster analysis (BCCA), principle component analysis (PCA), and correspondence analysis (CA) methods). The annual dataset belonging physical and chemical features in the reservoir was obtained by the monthly intervals between the years 2010 and 2011. A total of 15 parameters (temperature, dissolved oxygen (DO), biological oxygen demand (BOD5), light permeability, conductivity, salinity, chloride, pH, total hardness, Ca, Mg, NO2-N, NO3-N, o-PO4, SO4) have been monitored at three different sampling stations in the reservoir and a total of 495 observations were grouped statistically. The sampled periods have been classified into three different groups by using the BCCA. The results were supported by the PCA and CA statistical methods. Consequently, in order to determine and to evaluate for large complex datasets that belong to environmental properties, multivariate analyses are very useful techniques. Thus, the sampling periods to monitor the physicochemical including in a water resource can be determined.Öğe DIEL VERTICAL MIGRATION OF ZOOPLANKTON (CLADOCERA, COPEPODA, ROTIFERA) IN THE KADIKOY RESERVOIR (EDiRNE/TURKEY)(Parlar Scientific Publications (P S P), 2015) Guher, HuseyinThe present study, in which the diel vertical migration (DVM) of several zooplankton groups found in the Kadikoy Reservoir, was carried out during a 24-h period from7-8 May 2012. Vertical zooplankton samples were taken every 3-h eight times during a 24-h period, at 5-m intervals from the surface to the bottom, at the approximately the centre of the reservoir. An examination of zooplankton samples from the reservoir revealed a total of 36 taxa belonging to the Rotifera, Copepoda and Cladocera. An average of 371170 ind./m(3) Rotifera (67%), 122340 ind./m(3) Cladocera (22%) and 63928 ind./m(3) Copepoda (11%) was found an average of 557437 ind./m(3). The Cladocera and Copepoda populations were found mostly at 10th m and 15th in depths during daylight hours (13:00, 10:00, 16:00 and 19:00) and in surface layers during hours of darkness (01:00, 22:00 and 04:00). Generally, significant diel variation was not found in the Rotifera population. Abiotic factors, chlorophyll-a, time of day and depth significantly impacted the abundance of zooplankton; moreover, abiotic factors and chlorophyll-a were controlling factors on the vertical distribution pattern of the zooplankton in the reservoir. In addition, the main physicochemical conditions of the study area were found suitable for the life cycle of identified zoplankton populations.Öğe The diversity, abundance and seasonal distribution of planktonic microcrustacean (Copepoda, Cladocera) in Kayalikoy Reservoir (Kirklareli/Turkey)(Ege Univ, Fac Fisheries, 2021) Guher, Huseyin; Oterler, BurakThis study was carried out to determine the diversity, abundance and seasonal distribution of planktonic microcrustaceans (Cladocera, Copepoda) in Kayalikoy Reservoir. Cladocera and Copepoda samples were collected from May 2018 to April 2019 at three stations in the reservoir and some environmental parameters were measured. The qualitative evaluation of the samples revealed presence of 40 species, 24 from Cladocera and 16 from Copepoda, in the reservoir. The quantitative evaluation of the samples showed that 52690 ind./m(3) zooplankton on average was found in the reservoir. The most common species in the reservoir were Daphnia cucullata, D. longispina, D. pulex, Bosmina longirostris and Chydorus sphaericus from Cladocera, and Arctodiaptomus wierzejskii, Acanthocyclops robustus and Thermocyclops crassus from Copepoda. According to the water quality standards, the measured values of water temperature, dissolved oxygen, sulfate, salinity and chloride indicated the first quality of water, while the light permeability, nitrite-nitrogen, nitrate-nitrogen, ortho-phosphate and chlorophyll-a values indicated the second and third quality of water levels. According to these results, we conclude that Kayalikoy Reservoir has a mesotrophic character in terms of the microcrustacean fauna and the physicochemical parameters.Öğe The Dynamics of Zooplankton in National Park of Lake Gala (Edirne-Turkey)(Inst Zoology, Bas, 2011) Guher, Huseyin; Erdogan, Sevil; Kirgiz, Timur; Camur-Elipek, BelginIn this study, carried out at monthly intervals in four different stations between March 2004 and January 2005, it is aimed to have new knowledge on the dynamics of zooplankton communities and the effects of physical-chemical values of the Lake Gala. As a result of the study, a total of 76 species have been identified as 50 species belong to Rotifera, 15 species - to Cladocera, and 11 species - to Copepoda. Of these species Proalides tentaculatus de Beuchamp, 1907, Itura myersi WULFERT, 1935, Asplanchnopus hyalinus (HARRING, 1913) are found only in Turkish Thrace. As a result of quantitative evaluation of zooplankton samples, while an average of 35 334 ind./m(3) Rotifera, 19 305 ind./m(3) Cladocera, 72 369 ind./m(3) Copepoda was found an average of 127 008 ind./m(3) zooplankton organisms have been determined in the lake. According to the results of PCA analysis, when looking at the seasonal distribution of zooplankton species, it is seen that species assembled to form three groups as species which appear in spring, summer and winter. According to the results of RDA analysis, correlation (for RDA axis 1 0.956, for RDA axis 2 0.925) between zooplankton organisms and environmental variables being so high shows that Water tem, EC, SO4, Ca, pH, Chl-a, Secchi and PO4, are significant (p = 0.0020) factors determining the distribution of zooplankton organisms in the Lake Gala.Öğe Four New Rotifera Species of Turkish Fauna(Central Fisheries Research Inst, 2012) Erdogan, Sevil; Guher, HuseyinFour rotifer species were recorded from 3 freshwater bodies (Pedina and Hamam Lakes, Igneada-Kirklareli and Omerbey Stream, Uzunkopru- Edirne) in Turkish Thrace. These species, Trichocerca bicristata (Gosse, 1887), Gastropus minor (Rousselet, 1892), Erignatha clastopis (Gosse, 1886) and Encentrum kulmatyckii Wiszniewski, 1953, are new records for the Turkish fauna. Besides, the recorded species are illustrated and aspects of their distribution are represented.Öğe The Investigation of Zooplanktonic Organisms (Rotifera, Copepoda, Cladocera) of Meric River (Turkey)(Medwell Online, 2012) Guher, HuseyinThis study aims to determine the zooplankton fauna of Meric river where the samples were collected in monthly intervals March 2011 to February 2012 from 8 stations. At the end of the study, 52 species from Rotifera, 22 species from Cladocera and 12 species from Copepoda were observed. And also some chemical and physical parameters as pH, dissolved oxygen, water temperature and conductivity were determined and found to be in suitable values for zooplankton life.Öğe An investigation on the periphytic species of Rotifera in the Lake Gala (Turkey)(Inst Zoology, Bas, 2008) Erdogan, Sevil; Guher, HuseyinThis study was performed to determine the Rotifera species living on the Thypha sp., Nymphaea sp. and Ceratophyllum sp., and to put forward their macrophyte preferences, if they have been present in the Lake Gala National Park between June and December 2004. The effects of the physico-chemical parameters, which were measured in the lake, and the chlorophyl-a values of the macrophytes on the distribution of Rotifera species were also examined. As a result of the study totally 39 Rotifera species, belonging to 13 families, were found. Thirtytwo species on Thypha sp., 29 species on Nymphaea sp. and 21 species on Ceratophyllum sp. were determined. It was determined that Keratella tropica and Polyarthra remata prefered the Thypha sp., Trichotria pocillum and Lecane luna preferred the Nymphaea sp., Lecane quadridentata, Habrotrocha sp. and Rotoria rotatoria preferred the Ceratophyllum sp.Öğe Spatial and temporal evaluation of the physicochemical quality of domestic/industrial water in the Kirklareli Reservoir (Turkish Thrace)(Serbian Chemical Soc, 2022) Guher, Huseyin; Oterler, Burak; Elipek, Belgin Camur; Yeler, Okan; Aydin, Gazel BurcuThe Kirklareli Reservoir, located in the Meric-Ergene River Basin, is an important drinking/industrial freshwater resource of the Kirklareli Province. In order to ensure the sustainable use of this important reservoir, its current situation should be examined periodically and evaluated by multivariate analyses. For this reason, water samples were taken between the dates April 2018 and February 2019 at monthly intervals from 3 different stations. The data on the environmental and physicochemical variables (water temperature, dissolved oxygen, pH, salinity, conductivity, total dissolved solids, chlorophyll-alpha, light permeability, fluoride, chloride, NO2-N, NO3-N, PO4, SO4 and essential/potentially toxic elements) were measured and evaluated according to the classes of surface water quality control regulation of Turkey. The parameters exceeding first-class water quality values (chlorophyll-alpha, pH, NO2-N, chloride, selenium) were mapped in GIS using the spline integration approach. In addition, the sodium absorbtion ratio, Kelly index values and magnesium ratio, were calculated to evaluate the water quality for agricultural irrigation water standards. The water quality of the reservoir was evaluated using multivariance analyses (Bray-Curtis similarity index, correspondence analyses, Pearson correlation index). As a result, it was emphasized that the use of the GIS approach is a potential useful method for monitoring the sustainable water quality of the Kirklareli Reservoir, which was determined to have an oligomesotrophic character.
