Saklıgöl (Denizli) Population Size of Pelophylax bedriagae (Levantine frog) Species

Abstract

In this study, information is given about P. bedriagae’s population size and the changes that threaten the future of its population in the habitat that inhabits in Saklıgöl of Yukarıdağdere, Honaz. In this context, the population size of P. bedriagae was estimated as 544 (CI= 95%; 353-899) individuals. The average recapture probability and the average survival rate were calculated as 0.62 and 0.32 respectively. Generally, populations of wild organisms are under the risk due to anthropogenic habitat destruction. Frogs that are extremely sensitive against changes that may occur in the habitat are good indicators in the analysis of many biological problems and the identification of problems that may occur in wetlands.

Saklıgöl’de (Denizli) Pelophylax bedriagae (Levanten kurbağa) Türünün Populasyon Büyüklüğü

Abstract

Bu çalışmada Saklıgöl’de (Yukarıdağdere Köyü, Honaz, Denizli) yaşayan P. bedriagae’nin populasyon büyüklüğü ve populasyonun geleceğini tehdit eden etkenler hakkında bilgi verilmiştir. Bu kapsamda, P. bedriagae türünün Saklıgöl populasyonunun büyüklüğü 544 birey (% 95’lik Güven Aralığı= 353-899) olarak hesaplanmıştır. Yapılan bu çalışmada ortalama yakalanma olasılığı 0,62 ve ortalama hayatta kalma oranı 0,32 olarak hesaplanmıştır. İnsan kaynaklı habitat tahribatları nedeniyle doğal populasyonlar genellikle risk altına girmektedir. Habitatta meydana gelebilecek değişikliklere karşı son derece hassas olan kurbağalar, sulak alanlarda meydana gelebilecek sorunların belirlenmesinde ve birçok biyolojik problemin çözümlenmesinde iyi bir indikatör canlılardır.
