⚡ TL;DR(Too Long; Didn't Read)

Results showed that there was no difference between karyological values in island and continental populations of those rodents, although Aegean and Marmara seas have served as geographic barriers for a long time between islands and mainland.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:A chromosomal study on five different rodent species (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi and Rattus rattus) from Gökçeada and Bozcaada in Aegean Sea and Marmara Island in Marmara Sea was performed to fill the deficiency of karyological information about island populations of these species.
📊
Key Findings & Data:Diploid chromosome sets (2n) and fundamental numbers of chromosomal arms (NF) were determined to be 2n = 40, 40, 48, 48 and 38, NF = 40, 40, 48, 48 and 60 for M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi and R. rattus respectively.
💡
Conclusion & Impact:Results showed that there was no difference between karyological values in island and continental populations of those rodents, although Aegean and Marmara seas have served as geographic barriers for a long time between islands and mainland.

Abstract

A chromosomal study on five different rodent species (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi and Rattus rattus) from Gökçeada and Bozcaada in Aegean Sea and Marmara Island in Marmara Sea was performed to fill the deficiency of karyological information about island populations of these species. Diploid chromosome sets (2n) and fundamental numbers of chromosomal arms (NF) were determined to be 2n = 40, 40, 48, 48 and 38, NF = 40, 40, 48, 48 and 60 for M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi and R. rattus respectively. Results showed that there was no difference between karyological values in island and continental populations of those rodents, although Aegean and Marmara seas have served as geographic barriers for a long time between islands and mainland. In addition to the karyotypes of M. domesticus, M. macedonicus, A. sylvaticus and R. rattus, their presence in Marmara Islands were firstly determined by current study.

Özet

Beş farklı kemirici türünün (Mus domesticus, Mus macedonicus, Apodemus sylvaticus, Apodemus witherbyi ve Rattus rattus) Türkiye'deki ada populasyonlarına ilişkin karyolojik bilgi eksikliğini gidermek amacıyla, bu türlerin Ege Denizi'nde yer alan Gökçeada ve Bozcaada ile Marmara Denizi'nde yer alan Marmara Adası'nda yayılış gösteren populasyonları üzerine kromozomal bir çalışma gerçekleştirilmiştir. M. domesticus, M. macedonicus, A. sylvaticus, A. witherbyi ve R. rattus için diploit kromozom sayıları ve temel kromozom kol sayıları sırasıyla 2n = 40, 40, 48, 48 ve 38, NF = 40, 40, 48, 48 ve 60 olarak belirlenmiştir. Ege Denizi ve Marmara Denizi bu türlerin adalarda ve anakarada yayılış gösteren populasyonları arasında gen akışının kesilmesine neden olan coğrafik bariyerler olarak uzun süredir görev yapmaktadır, buna rağmen, bu çalışma ile bu kemirici türlerinin adalarda ve anakarada yayılış gösteren populasyonları arasında karyolojik bakımdan herhangi bir farklılaşma olmadığı tespit edilmiştir. Ayrıca, M. domesticus, M. macedonicus, A. sylvaticus ve R. rattus'un Marmara Adası'nda yayılış gösterdiği ilk kez bu çalışma ile belirlenmiştir.
