Öğe AGE, ADULT SURVIVAL RATE, AND ADULT LIFE EXPECTANCY OF A Podarcis tauricus POPULATION (REPTILIA: LACERTIDAE) FROM SAROS BAY, TURKEY(Folium Publ Co, 2016) Altunisik, Abdullah; Kalayci, Tugba Ergul; Uysal, Ibrahim; Tosunoğlu, Murat; Ozdemir, NurhayatIn this study, the age composition of a Podarcis tauricus population from Saros Bay (northwest Turkey) was determined by skeletochronology. 27 preserved adults (20 female female, 5 male male, 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.Öğe Hematology of Triturus karelinii (STRAUCH, 1870), from Gallipoli, Turkey(Osterreichische Gesellschaft Herpetologie E V, 2013) Tosunoğlu, Murat; Gul, Cigdem; Uysal, Ibrahim[Anstract Not Available]Öğe The Effect of Medical Students’ Problem-Solving Perceptions and Achievement on Clinical Reasoning Levels(Seyit Ahmet KIRAY, 2022) Tekın, Murat; Yurdal, Mustafa Onur; Uysal, Ibrahim; Aytug-kosan, Aysen Melek; Toraman, CetinClinical reasoning is important in medical education in terms of achieving the purpose of clinical practice. 3 cases in which clinical reasoning prepared by relevant experts from 3 different departments were applied to Year-5 students. As an indicator of academic success, the final grade of the internship and the general success average were taken. Problem solving perception scale was applied. This research aimed to examine the relationships between the problem solving, clinical reasoning and academic achievement levels of medical students. It was observed that clinical case evaluations showed a positive correlation with each other, a positive correlation was found between clinical case evaluations and problem solving perception, and the final grade of internship and GPA did not correlate with both clinical case assessment and problem solving perception. It is necessary to determine whether the clinical reasoning processes are used adequately by the students in medical education and the education programs should be reviewed and arranged accordingly.Öğe The herpetofauna of the east Turkish province of Igdir(Osterreichische Gesellschaft Herpetologie E V, 2010) Tosonoglu, Murat; Gul, Cigdem; Dincaslan, Yunus Emre; Uysal, Ibrahim[Anstract Not Available]Öğe The population of Mauremys rivulata (VALENCIENNES, 1833) on the Island of Bozcaada, Turkey(Pensoft Publishers, 2014) Gul, Cigdem; Tosunoğlu, Murat; Hacioglu, Nurcihan; Caprazli, Tugce; Erdugan, Huseyin; Uysal, Ibrahim[Anstract Not Available]Öğe Tracking the timing of Neotethyan oceanic slab break-off: Geochronology and geochemistry of the quartz diorite porphyries, NE Turkey(Pergamon-Elsevier Science Ltd, 2020) Karsli, Orhan; Dokuz, Abdurrahman; Aydin, Faruk; Uysal, Ibrahim; Sengun, Firat; Kandemir, Raif; Santos, Jose FranciscoThe initiation of the break-off of the northern branch of the Neotethyan oceanic lithosphere is an important but poorly understood event in the geology of the Sakarya Zone (SZ) in northeastern Turkey. Although it is wellknown that Latest Cretaceous intrusives (-70 Ma) and early Eocene adakitic magmatic rocks are present in the eastern SZ, the outcrops of the early Eocene non-adakitic rocks are very limited, and their tectono-magmatic evolution has not been studied. We describe a small outcrop of non-adakitic quartz diorite porphyry in the Kov area of the Gumushane region in northeastern Turkey. The genesis of these porphyries is significant in evaluating the syn-to post-collision-related magmatism. The LA-ICP-MS zircon U-Pb dating revealed that the Kov quartz diorite porphyries (KQDP) formed at ca. 50 Ma, coeval with adakitic rocks, and-20 Myr later than the slab rollback-related intrusive rocks. The KQDPs are calc-alkaline in composition and enriched in large ion lithophile elements (LILEs) and light rare earth elements (LREEs) and depleted in high field strength elements (HFSEs; e.g., Nb, Ta, Ti), with significant negative anomalies of Nb, Ta, and Ti but positive anomalies of Th, U, and Pb. Isotopic compositions of the samples show limited range of variation and slight enrichment of 87Sr/86Sr(t) (0.70489 to 0.70555), epsilon Nd(t) (-1.4 to -1.2) with TDM of 1.11 to 1.61 Ga. Pb isotopic ratios of the samples point to an enriched mantle source. They were likely crystallized from the melt that originated from an EM2-type spinel-facies subcontinental lithospheric mantle (SCLM), followed by the fractionation with insignificant crustal assimilation. The SCLM was metasomatically enriched, and the metasomatic agent was likely H2O-rich fluids rather than sediments released from subducting oceanic crust during the Late Cretaceous closure of the Neotethyan oceanic lithosphere. In conjunction with the geological background and previous data, we propose that the generation of the KQDPs resulted from a slab break-off event that caused ascending or infiltration of hot asthenosphere, triggering mantle melting. Such sporadic occurrences of the KQDPs, with coeval adakitic rocks in the SZ, are likely associated with the onset of extensional tectonics due to the earlier stage of slab break-off along the region during the early Eocene period.
