    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, 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 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.

    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

    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.
