    Age structure and body size of the Strauch’s racerunner, Eremias strauchi strauchi Kessler, 1878
    (2013) Altunışık, Abdullah; Gül, Çiğdem; Özdemir, Nurhayat; Tosunoğlu, Murat; Ergül, Tuğba
    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 Iğdır (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.

    Age, adult survival rate, and adult life expectancy of a Podarcis tauricus population (reptilia: lacertidae) from saros bay, Turkey
    (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.

    Body size and age structure of the Parvilacerta parva (Boulenger, 1887) population from Sivas, Turkey
    (2020) Kalaycı, Tuğba Ergül; Uysal, İbrahim; Gül, Çiğdem; Özdemir, Nurhayat
    Longevity and age of sexual maturity are key life history trait factors directly linked to ecological and evolutionary aspects. In this study, we determined age structure of Parvilacerta parva individuals from Sivas (Turkey) using skeletochronology. The maximum age was found to be seven years for females and six years for males of P. parva. A significant relationship was found between age and body size in individuals whose head length, head width and body length were measured. Additionally, it was seen that there is a significant relationship among body length, head length and head width.

    Sivas Heremites vittatus (Şeritli Kertenkele) (Olivier, 1804) örnekleri üzerinde İskelet kronolojisi yöntemi ile yaş tayini
    (2018) Kalaycı, Tuğba Ergül; Altunışık, Abdullah; Uysal, İbrahim; Tosunoğlu, Murat; Özdemir, Nurhayat
    Sürüngenlerde yaş yapısının, eşeysel olgunluk yaşının ve ömür uzunluğunun bilinmesi onların yaşam öyküsüözelliklerinin ekolojik ve evrimsel yönleri ile anlaşılmasında yardımcı olmaktadır. Bu çalışmada, Sivas (Türkiye)’tanHeremites vittatus (Şeritli Kertenkele) türüne ait dişi bireylerin yaş yapısı ilk defa ortaya konulmuştur. Buna göre enuzun yaşam uzunluğu bu türün dişi bireyleri için 5 yıl olarak tespit edilmiştir. Baş uzunluğu, baş genişliği ve vücutuzunluğu belirlenen bireylerde, yaş ve vücut boyu arasında anlamlı bir ilişki tespit edilmiştir. Bununla birlikte, vücutuzunluğu, baş uzunluğu ve baş genişliği arasında da anlamlı bir ilişki mevcuttur.
