Rodent species in 17 selected localities were determined, and these localities were then compared with respect to rodent species composition. It was determined that a total of 27 rodent species are found in these localities, the number in each locality ranging from 6 to 12.

It was determined that a total of 27 rodent species are found in these localities, the number in each locality ranging from 6 to 12. Species previously recorded in mixed and decidous forests in northern Asiatic Turkey, such as Glis glis, Muscardinus avellanarius, Microtus subterraneus and Clethrionomys glareolus, were found not to range across forested localities in west and south Asiatic Turkey in the dry summer season. It was also determined that rodents, which live in similar habitats in different localities, showed considerable differences in species composition, and therefore the similarity coefficients between the localities ranged from 1 to . In this connection, vegetation structure, climate and altitude were found to be the main factors effecting the distribution of rodent species in Asiatic Turkey.

Asiatik Türkiye’deki Kemirici Türlerinin Coğrafik Dağılışı ve Habitatlarının Ekolojik Analizleri Üzerine Katkılar Özet: Seçilmiş 17 lokalitedeki kemirici türleri belirlendi ve bu lokaliteler kemirici tür kompozisyonlarına göre karşılaştırıldı. Bu lokalitelerde toplam olarak 27 kemirici türünün yayılış gösterdiği ve herbir lokalitideki kemirici tür sayısının 6 ile 12 arasında değiştiği saptandı. Glis glis, Muscardinus avellanarius, Microtus subterraneus ve Clethrionomys glareolus gibi kuzey Türkiye’deki karışık ve yaprak döken ormanlardan daha önce kaydedilmiş olan türlerin nemsiz ve kuru bir yaz sezonuna sahip batı ve güney Türkiye’deki ormanlık .
