    A serological investigation of Pelodytes caucasicus and Pelobates syriacus (Amphibia, Anura) populations in Turkey
    (2007) Tosunoğlu, Murat; Arikan, Hüseyin
    Blood serum proteins of specimens belonging to Pelodytes caucasicus and Pelobates syriacus populations were compared qualitatively and quantitively by means of polyacrylamide disc electrophoresis and densitometry methods. It was determined that the blood serum proteins of both populations demonstrated qualitative and quantitive differences. This result supports the morphological and osteological studies emphasizing the fact that the genus Pelodytes needs to be treated as a separate family (Pelodytidae). © TÜBİTAK.

    A STUDY ON MICROFLORA IN ORAL AND CLOACAL OF FRESHWATER TURTLES (Emys orbicularis Linnaeus, 1758 and Mauremys rivulata Valenciennes, 1833) FROM KAVAK DELTA (CANAKKALE)
    (Parlar Scientific Publications (P S P), 2012) Hacioglu, Nurcihan; Dulger, Basaran; Caprazli, Tugce; Tosunoğlu, Murat
    Deltas are reservoirs for important plant and animal species and have a vital role in maintaining sustainability of ecological balance. In addition, because of anthropogenic pressure they are recognized as natural habitat of pathogenic microorganisms and infectious diseases caused by these bacteria are dangerous to aquatic animal's health and could potentially affect several species as well those are endangered. This study aims to determine the micro-flora of freshwater turtles (Emys orbicularis Linnaeus, 1758 and Mauremys rivulata Valenciennes, 1833) and sensibilities of these turtles against isolated pathogenic bacteria. Furthermore the investigation was conducted to characterize diseases causative agents. Their risks to animal and human health are difficult to carry out, especially for some turtle species. The results showed that the isolates were identified as Vibrio spp. and Proteus spp. So, these bacteria are the main pathogens isolated from E. orbicularis and M. rivulata. These data appoint the importance of epidemiological surveillance and microbiological monitoring and reinforce the need to implement environment protection programs especially for the threatened turtle species (E. orbicularis).

    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.

    (Folium Ltd, 2016) Altunışık, Abdullah; Kalayci, Tuğba Ergül; Uysal, İbrahim; Tosunoğlu, Murat; Özdemir, Nurhayat
    In this study, the age composition of a Podarcis tauricus population from Saros Bay (northwest Turkey) was determined by skeletochronology. 27 preserved adults (20??, 5??, 2 juveniles) were evaluated and the maximum observed lifespan was recorded to be 7 years in females and 6 years in males. The mean age was 5.2 ± 0.2 years in males and 5.0 ± 0.2 years in females; the mean snout-vent length (SVL) was 63.0 ± 0.7 mm (range: 60.4-64) in males and 61.3 ± 0.9 mm (range 52.4-68.5) in females. No significant differences were found between sexes in terms of body size, but the sexual dimorphism index (SDI), was determined as 0.03, indicating a weakly malebiased. Adult survival rate and adult life expectancy were estimated to be 0.51 and 2.54 for female individuals, respectively. The lizards reached sexual maturity between 2 and 3 years. No significant difference was found between the sexes in terms of age and head sizes. The age and SVL were correlated only in females. Additionally, a significant positive correlation was found among SVL, head length (HL), and width (HW) in females. © 2016 Folium Publishing Company.

    (Parlar Scientific Publications, 2021) Kaya, Nilgün; Tosunoğlu, Murat
    Studies that aim to discover amphibian and reptilian species were conducted in the Istanbul islands which consists of Buyukada, Heybeliada, Burgazada and Kinaliada, during the years 2016-2019. The latest research of the islands was done 39 years ago and no studies were conducted since then. This study investigated the differences in species of amphibians and reptiles over these years. Bufotes variabilis (Pallas, 1769) from Buyukada, Hemidactylus turcicus (Linnaeus, 1758) from Heybeliada and Testudo graeca Linnaeus, 1758 from Kinaliada were given as new records from these localities. Principal components analysis (PCA) was applied to analysis the correlation of the amphibian and reptile diversity between Istanbul islands, Marmara islands and mainland. PC1 (eigenvalue of 1.91082) was accounted for 45.86 % of the variation. Results of PCA, Podarcis sloth's (Rafinesque & Schmaltz, 1810) was observed to display an extant and dominant population in all of the islands. Hierarchical Cluster Analysis was performed to assess the similarity in species among the islands. According to HCA, three cluster groups were formed. Islands of Istanbul have separate groups from other islands and mainland.

    Assessment of nuclear abnormalities in erythrocytes of balkan pond turtle mauremys rivulata (Valenciennes, 1833) (Testudines: Geoemydidae) from the Biga Stream, Çanakkale, Turkey
    (Bulgarian Academy of Sciences, 2019) Çördük, Nurşen; Hacıoğlu Doğru, Nurcihan; Gül, Çi?dem; Tosunoğlu, Murat
    Reptilian species are potentially efficient bioindicators of pollution and habitat destruction. Turtles may be especially useful for monitoring the chemical contamination of their habitats. The aim of this study was to assess the genotoxic effect of environmental pollutants on Balkan pond turtle Mauremys rivulata (Valenciennes, 1833) from the Biga Streamp Canakkale, Turkey. Healthy mature animals were collected using the hand-capture method from four stations: Estuary zone, city centre, buffer zone and industrial zone of the stream. Blood samples of live specimens were obtained in within one day of their capture. The peripheral blood smears for each specimen were prepared, fixed with methanol for 15 min and dyed with Giemsa stain. Micronuclei and other nuclear abnormalities such as blebbed, kidney-shaped, lobed and notched nuclei were identified. Comparing the nuclear abnormalities in the samples, it was determined that their frequency was highest in the samples collected from the station in the city centre (9.16±0.02). The results indicated that the levels of genotoxic pollutants in different regions of the Biga Stream lead to DNA damage in Mauremys rivulata. © 2019 Bulgarian Academy of Sciences.

    Blood Cell Types and Abnormalities in Free Ranging Hermann’s Tortoise (Testudo hermanni) Populations from Different Habitats
    (2024) Boran, Begüm; Baycan, Bengi; Gül, Çiğdem; Tosunoğlu, Murat
    Testudo hermanni is considered near threatened globally in the wild. In this study differential leukocyte percentages, nuclear abnormalities, and erythrocyte morphology abnormalities of Testudo hermanni populations from two different habitat types in the Thrace Region were determined to whether habitats have a potential effect on blood cells. A total of 37 tortoises, 18 from an open habitat in Kırklareli/Karakoç, and 19 from an isolated habitat in Edirne/Keşan were studied. According to the results obtained from the Micronucleus Test, which detects genotoxic damage, there was no statistically significant difference between the two habitats. There were statistically significant differences in erythrocyte morphology abnormalities and differential leukocyte count between two populations, such as frequencies of anucleated erythrocyte, nuclear shift, elliptical shape distortion, monocyte and eosinophile percentages. This is the first study examined nuclear abnormalities of Testudo hermanni in Türkiye.

    Breeding and Cannibalism Behaviours of Captive Coronella austriaca (Colubridae) in a Terrarium
    (2019) Uysal, İbrahim; Gül, Çiğdem; Tosunoğlu, Murat
    Cannibalism involves consuming all or part of another individual of the same species as food. Consuming the same species, or showing cannibalistic behaviour is common in reptiles, especially in snake species. The captured female Coronella austriaca of the Colubridae family was kept in captivity for two months in the terrarium. The female sample fed on one of the offsprings after ovoviviparous delivery. In the following observations it was determined that one of the juvenile individuals fed on another juvenile with similar size. The objective of this study is to provide information about the breeding and cannibalistic behaviour of Coronella austriaca under captivity.
