Abstract

In this study, the Turkish population of Rattus norvegicus and Rattus rattus were studied with regard to external, cranial, phalli, bacula and tooth crown morphology and karyotype. External, internal and karyologic characteristics of R. norvegicus were found to be consistent with previously published results. Additionally, it was determined that there are striking color variations in the dorsal and ventral fur of R. rattus and that crown morphology is not a definitive characteristic distinguishing these species because of connected lobes in old specimens. According to the karyological studies, the diploid chromosome numbers and fundamental numbers of R. norvegicus and R. rattus were found to be 42, 38 and 64, 60, respectively.

Özet

Bu çalışmada, Rattus norvegicus ve Rattus rattus’un Türkiye populasyonları eksternal, kranial, fallus, bakulum, dis morfolojileri ve karyolojileri dikkate alınarak araştırıldı. R. norvegicus’un eksternal, internal ve karyolojik karakterlerinin literatüre tamamen uyduğu saptandı. Ayrıca R. rattus’un dorsal ve ventral kürkünde çok değişik renk varyasyonların bulunduğu ve yaşlı örneklerde diş loblarının birleşmesi nedeniyle diş morfolojisinin bu iki türün ayrımında belirleyici bir karakter olmadığı belirlendi. Karyolojik çalışmalarda R. norvegicus ve R. rattus’un diploid ve temel kromozom kol sayılarının sırasıyla 42, 38 ve 64, 60 oldugu bulundu.
