    Age structure and body size of the Strauch's racerunner, Eremias strauchi strauchi Kessler, 1878
    (Tubitak Scientific & Technological Research Council Turkey, 2013) Altunisik, Abdullah; Gul, Cigdem; Ozdemir, Nurhayat; Tosunoğlu, Murat; Ergul, Tugba
    We studied, for the first time, the age structure of Eremias strauchi strauchi (Kessler, 1878) from a sample (18 adults) of a population living in the vicinity of Igdir (eastern Turkey) using the skeletochronological method. The maximum observed longevity was 7 years for males and 5 years for females. The age of males ranged from 4 to 7 years (mean 4.91, n = 12), while that of females ranged from 4 to 5 years (mean 4.66, n = 6). The average snout-vent length (SVL) was 61.10 mm in males and 60.82 mm in females. The differences in mean age and SVL between sexes were not statistically significant. Intersexual differences in body size were male-biased, but this state was not statistically significant. Age and SVL were positively correlated in both sexes.

    Changes in the blood composition of some anurans
    (Firenze Univ Press, 2011) Gul, Cigdem; Tosunoğlu, Murat; Erdogan, Didem; Ozdamar, Dilsah
    We examined some hematological parameters (red blood cell count, white blood cell count, haemoglobin concentration, hematocrit value, mean cell volume, mean cell haemoglobin, mean cell haemoglobin concentration and plasma total protein) on five anuran species of terrestrial (Pseudepidalea viridis, Pelobates syriacus and Hyla arborea), semi-aquatic (Rana dalmatina) and aquatic (Pelophylax ridibundus) nature from Canakkale, Turkey. Differences between males and females in terms of haemoglobin, hematocrit and mean cell volume in P. viridis were statistically significant. The RBC count was higher in terrestrial and aquatic species than in semi-aquatic species. Haemoglobin concentration, hematocrit value, MCV and MHC were higher in terrestrial species than in semi-aquatic and aquatic species. The MCHC values were all similar to each other. The plasma total protein was higher in terrestrial species than in aquatic species. To sum up, variations were detected in the some hematological parameters under examination among the anuran species.

    Determination of the effects of environmental pollution on the Balkan terrapin, Mauremys rivulata (Valenciennes, 1833) br
    (Akademiai Kiado Zrt, 2022) Dogru, Nurcihan hacioglu; Gul, Cigdem; Cordur, Nursen; Tosunoğlu, Murat
    The effects of environmental pollution on three populations of the Balkan terrapin [Mauremys rivulata (Valenciennes, 1833)] from the Bozcaada, Giikceada and Dardanos regions were evaluated. The morphological parameters of Balkan terrapins collected on each site were measured and blood samples were taken for haematological analysis and micronucleus detection. The physicochemical, microbiological and microelement analyses of the water samples from each region were conducted by standard methods. The highest red blood cell, white blood cell and mean corpuscular haemoglobin concentration values were seen in the samples from Giikceada. The highest haemoglobin value was found in the samples originating from Bozcaada, whereas the highest haematocrit and mean corpuscular volume values were found in the animals from Dardanos. Based on the microbiological analysis of the water samples, the most polluted site was Giikceada. The microelement contents of the water and blood samples were different at the three sites, the lowest being in the Giikceada area. It was revealed that the percentage of red blood cell micronuclei and other nucleus abnormalities in the M. rivulata blood samples was the lowest also in the animals living in the region of Giikceada.

    Effects of Varying Ecological Conditions on the Blood Parameters of Freshwater Turtles in Canakkale (Turkey)
    (Foundation Environmental Protection & Research-Fepr, 2011) Tosunoğlu, Murat; Yilmaz, Nilgun; Gul, Cigdem
    This study examined the effect of variations in the water characteristics (dissolved oxygen, pH, conductivity and temperature) of the biotopes of freshwater turtles (Emys orbicularis and Mauremys rivulata) collected from different localities in Canakkale, Turkey on the blood parameters and put forward the variations in blood parameters for survival during wet and dry periods. According to the water quality of their biotopes, differences were detected in the erythrocyte and leukocyte counts of the species E. orbicularis and in the erythrocyte and leukocyte counts as well as in the MCV (mean cell volume) and MCH (mean cell hemoglobin) values in M. rivulata. In the species E. orbicularis, differences were detected in the biochemical sense in total protein and urea quantities between dry and wet periods.

    Genetic variability and population genetic structure in the Caucasian Parsley Frog, Pelodytes caucasicus (Boulenger, 1896) based on microsatellite markers
    (Taylor & Francis Ltd, 2024) Kalayci, Tugba Ergul; Gul, Cigdem
    The Caucasian Parsley Frog, Pelodytes caucasicus (Boulenger, 1896), is endemic to Caucasia, and its population is decreasing. Here, we present information on the genetic structure and diversity of populations from four provinces of T & uuml;rkiye (Giresun, Trabzon, Rize, and Artvin) using microsatellite markers. Despite their small geographic range, the species' populations showed moderate genetic differentiation, which could be a result of rapid genetic drift. Our results show that Trabzon and Giresun populations are genetically different from those of Rize and Artvin. We found considerably low genetic diversity in Artvin, Trabzon, and Giresun populations. The inbreeding co-efficient is also high in those localities (H-O

    Genomic Variation within Laudakia stellio (Linnaeus, 1758) (Sauria: Agamidae in Turkey, Based on Analyses of Mitochondrial 12S rRNA Sequences
    (Medwell Online, 2011) Ozdemir, Nurhayat; Gul, Cigdem; Tosunoğlu, Murat
    The starred agama, Laudakia stellio (Linnaeus, 1758) has a wide distribution from Northern Africa to Southeast Europe and Southwest Asia and was thought to form two subspecies, Laudakia stellio-stellio (Linnaeus, 1758) and Laudakia stellio-daani in Turkey. Almog examined specimens from Greece, Aegean Islands and Anatolia for exploring the systematic status of L.s. daani relative to L.s. stellio. They recognized the whole Anatolian populations as L.s. daani indicating that the question of the eastern boundary of the subspecies remains open, Delos and Mykonos populations as L.s. stellio and emphasized the ambiguity of the taxonomic status of South-east Anatolia populations. So partial sequences (404 bp) of the mitochondrial 12S ribosomal RNA gene of six populations were sequenced to examine the genomic variation of the species in Anatolia. The analyses clearly suggest that two distinct mtDNA lineages exist in Turkey separated by 2.28 and 4.51% for the 12S rRNA sequences and conclude that the South, Blacksea and Aegean regions may represent L. stellio-daani because morphologically they fit the subspecies L.s. daani, however the southeast region remains to be addressed.

    Haematological and Genotoxicological Effects of Water Quality on Pelophylax bedriagae (Camerano, 1882) (Anura: Ranidae) and Mauremys rivulata (Valenciennes, 1833) (Testudines: Geoemydidae) in Canakkale, Turkiye
    (Inst Zoology, Bas, 2024) Boran, Begum; Gul, Cigdem
    Haematological and genotoxicological parameters of the Levant green frog Pelophylax bedriagae (Camerano, 1882) and the Western Caspian turtle Mauremys rivulata (Valenciennes, 1833) were studied. These species inhabited two sites with differing water quality in the Sar & imath;Cay Stream passing through the city centre of Canakkale, T & uuml;rkiye. We examined whether the two species were affected by the water quality classes identified based on physical and chemical properties of the water.Statistically significant differences were found between the two sites in terms of the frequencies of micronucleus, lobbed, notched, kidney-shaped and blebbed nuclei, as well as total nuclear abnormality in Pelophylax bedriagae. Moreover, a higher rate of nuclear abnormalities was observed at the more polluted site, classified as water quality class IV. Statistically significant differences were observed in the haematocrit value, percentages of lymphocytes, eosinophils, heterophils and basophils, erythrocyte width and frequencies of lobbed and kidney-shaped nuclei as well as the heterophil/lymphocyte ratio, often used as a stress indicator, in Mau-remys rivulata. In this species, it was determined that parameters other than lymphocyte and eosinophil percentages were higher in specimens from the more polluted site.

    Hematological reference intervals of four agamid lizard species from Turkey
    (Pensoft Publishers, 2011) Gul, Cigdem; Tosunoğlu, Murat
    Four agamid species, Laudakia caucasia (EICHWALD, 1831), Laudakia stellio (LINNAEUS, 1758), Phrynocephalus horvathi ROSTOMBEKOV, 1938 and Trapelus lessonae (DE FILIPPI, 1865), occurring in Turkey, were hematologically examined [erythrocyte and leukocyte count, total hemoglobin, hematocrit value, mean cell volume, mean cell hemoglobin, mean cell hemoglobin concentration and total protein values]. In addition, blood smears were prepared from the specimens and erythrocyte length, width, size and leukocyte diameters (lymphocyte, monocyte, eosinophil, heterophil, basophil) were measured and the percentage values of leukocyte types were calculated. The erythrocyte count in L. caucasia was found out to be higher than those of L. stellio and P horvathi. The erythrocyte size in L. stellio was larger than those of L. caucasia, P. horvathi and T. lessonae, respectively. The hemoglobin concentration, hematocrit percentage and mean cell hemoglobin parameters are different among L. caucasia, L. stellio and P. horvathi.

    (Tubitak Scientific & Technological Research Council Turkey, 2011) Tosunoğlu, Murat; Gul, Cigdem; Yilmaz, Nilgun; Topyildiz, Huseyin
    In this study, some blood parameters were studied in 7 distinct snake species (Dolichophis caspius, Eirenis modestus, Malpolon monspessulanus, Natrix natrix, Platyceps rubriceps, Telescopus fallax, and Typhlops vermicularis) of the families Colubridae and Typhlopidae, collected from various regions of Turkey. A total of 7 hematologic parameters, namely red blood cell count (RBC), white blood cell count (WBC), hematocrit value (HCT), hemoglobin concentration (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC), were examined. It was detected that Platyceps rubriceps had the highest erythrocyte count and the lowest MCV value among the species examined, Telescopus fallax had the lowest erythrocyte count and hematocrit value, and Eirenis modestus had the highest hematocrit and MCV values. With this study, the variations observed in the blood measurements and counts of snakes were also observed in clinical parameters.

    Hematological values in hermaphrodite, Bufo bufo (Linnaeus, 1758)
    (Univ Oradea Publ House, 2009) Donmez, Fatma; Tosunoğlu, Murat; Gul, Cigdem
    Five male, four female, and nineteen hermaphrodite Bufo bufo specimens were examined in terms of six hematological parameters, namely; red blood cell count, hemoglobin concentration, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration. The erythrocyte count and hematocrit of hermaphrodite specimens were found to be more than those of males and females in the prereproductive period. When all parameters were compared between sexes during the reproductive period, no significant differences were encountered. In addition, red blood cell count and hematocrit values were found to be higher among all sexes in the reproductive period than in the pre-reproductive period.

    Monitoring of micronuclei and nuclear abnormalities In Pelophylax ridibundus erythrocytes from the Biga Stream (Canakkale, Turkey)
    (Parlar Scientific Publications, 2018) Corduk, Nursen; Hacioglu-Dogru, Nurcihan; Gul, Cigdem; Tosunoğlu, Murat
    In this study, the frequency of micronuclei and nuclear abnormalities caused by environmental pollutants were determined in Pelophylax ridibundus from the Biga Stream (Canakkale, Turkey). Healthy and mature animals were collected by hand capture method from along the four stations (estuary zone, city center, buffer zone and industrial zone) of Biga Stream. Blood samples of the live specimens were obtained in the laboratory within one day of their capture. Two peripheral blood smears for each sampled specimen were prepared on clean slides, fixed with methanol for 15 min and dyed with Giemsa stain. Micronuclei and other nuclear abnormalities such as kidney shaped nuclei, lobed nuclei, and notched nuclei and blebbed nuclei were determined and scored in the slides. Also, heavy metal analysis was carried out to determine the pollution level of the waters in the stations. Our result have shown that the frequency of nuclear abnormalities were highest in Station 2 (8.64±0.51). However, the station 2 has higher rates of values of Al, Cu, Zn and Fe than the values obtained from the other stations. The results have showed that the amount of heavy metals contained in the stations was found to be close parallels with the percentage of the total nuclear abnormalities and each kind of abnormality in P. ridibundus erythrocytes. The results have indicated that the levels of genotoxic pollutants in different regions of the Biga stream differ and lead to DNA damage on the organisms. © by PSP.

    On the age structure of two samples of Lacerta trilineata BEDRIAGA, 1886, from different altitudes in Turkey (Squamata: Sarnia: Lacertidae)
    (Osterreichische Gesellschaft Herpetologie E V, 2018) Kalayci, Tugba Ergul; Gul, Cigdem; Tosunoğlu, Murat; Ozdemir, Nurhayat
    The authors studied the age composition in two samples (Edirne: 17 m a.s.l. and Bolu: 1,250 m a.s.l.) of Lacerta trilineata BEDRIAGA, 1886, in Turkey. Aging by skeletochronology showed that the maximum age of the lizards was about seven years in the Bolu and five in the Edirne sample. The adult survival rate was 0.59 % in males and 0.24 % in females of Bolu. The adult life expectancy was calculated as 2.94 years for males and 1.82 for females in the Bolu sample. Age at sexual maturity was two years in both samples. Although the mean age of the high altitude sample was older than of the low altitude sample, the mean snout-vent-length of the latter was longer.
