Özet:

 In this study, age determination of male and female adult Pelophylax ridibundus individuals captured from around the Gölbaşı Lake. Tailless frogs of age was defined by the skeletal chronology method. The fourth toes of the hind legs were used in this method. Age was determined counted on the Resting Lines RL of the phalanges. The mean ages of frogs were female 3.72  0.97 years range 2-7 and male 3.770.87 years range 3-6 respectively. There was no significant difference between the ages of female and male frogs P0.05. The mean weights of female and male frogs were found to be 62.918.57 g and 42.7710.74 g, respectively. This difference among the weights was significant P0.05. The mean snout- vent length SVL value was measured as 74.7111.91 mm for females and 71.77.25 mm for males. There was no significant difference in SVL among both sexes P0.05. In addition, it was defined a significant correlation among the SVL of female r0.889, P0.01, N36 and male frogs r0.833, P0.01, N18 age. As a result of the study, it was seen that the frogs have a young population structure.

 Bu çalışmada, Gölbaşı Gölü çevresinden yakalanan yetişkin erkek ve dişi Pelophylax ridibundus bireylerinin yaşlarının belirlenmesi amaçlanmıştır. Kuyruksuz kurbağaların yaşı iskelet kronolojisi yöntemine göre belirlenmiştir. Bu yöntemde, kurbağaların arka bacaklarının dördüncü ayak parmakları kullanılmaktadır. Yaş, falanjlardaki Dinlenme Halkaları RL üzerinden sayılarak belirlenmiştir. Kurbağaların ortalama yaşları sırasıyla dişi 3.72  0.97 yıl 2-7 aralığı ve erkek 3.770.87 yıl 3-6 aralığı bulunmuştur. Dişi ve erkek kurbağaların yaşları arasında anlamlı bir fark görülmemiştir P0.05. Dişi ve erkek kurbağaların ortalama ağırlıkları sırasıyla 62.918.57 g ve 42.7710.74 g olarak bulunmuştur. Ağırlıklar arasındaki bu fark anlamlıdır P0,05. Burun deliği-Kloak arası uzunluğu SVL ortalama değeri dişilerde 74.7111.91 mm, erkeklerde ise 71.77.25 mm olarak ölçülmüştür. Her iki cinsiyet arasında SVL açısından anlamlı bir fark yoktur P0.05. Ayrıca, dişi r0.889, P0.01, N36 ve erkek kurbağaların r0.833, P0.01, N18 yaşları ile SVL arasında anlamlı bir korelasyon olduğu belirlenmiştir. Çalışma sonucunda, kurbağaların genç bir nüfus yapısına sahip olduğu görülmüştür.
