    Allozyme variation in bank vole, Myodes glareolus (Mammalia: Rodentia) in Northern Anatolia
    (PERGAMON-ELSEVIER SCIENCE LTD, 2013) Colak, Reyhan; Kandemir, Irfan; Karacan, Gul Olgun; Kankilic, Teoman; Colak, Ercument; Yigit, Nuri; Ozkurt, Sakir Onder
    A total of 94 specimens from 16 populations of Myodes glareolus, collected between 2004 and 2007, from different altitudinal distributions were analyzed, using 16 enzyme systems. We found that 10 out of 22 loci (Idh-2, alpha-Gpdh, Me, Pgm, Pgd, Mdh-s, Ada, Est-1, Ldh-1, and Ldh-2) were polymorphic. Group 1 included population from altitudes ranging from 27 to 605 m above sea level (ASL), and Group 2 were from altitudes ranging from 1003 to 1288 m ASL. The summaries of the genetic parameters also displayed differences between the 2 groups. The possible reasons of such fragmentation between M. glareolus populations were discussed.

    Contributions on the southern distribution of Vespertilio murinus Linnaeus, 1758 (Chiroptera: Vespertilionidae) from Turkiye
    (Tubitak Scientific & Technological Research Council Turkey, 2022) Karatas, Ahmet; Bulut, Safak; Sefali, Abdurrahman; Toprak, Ferhat; Sahin, Mehmet Kursat; Ozkurt, Sakir Onder
    Vespertilio murinus Linnaeus, 1758, has a wide distribution from France to Japan, and from Iran in the south to Scandinavia and Russia in the north. The only records of the parti-coloured bat, Vespertilio murinus known from Turkey so far were based on subfossils, remains from owl pellets, and ultrasound recordings. We present the first records of live individuals from two Turkish provinces, Ardahan and Bayburt. Additionally, based on echolocation call records, its known distribution in the Anatolian Peninsula was proved to be wider. The global distribution of the species has been mapped by using ecological niche modelling. The results revealed that its distribution is highly influenced by precipitation dynamics. Although no cases of domestic cat predation on bats have previously been documented in Turkey, this paper also provides the first case study of V. murinus predated by a domestic cat in Ardahan, in November 2003.

    On the karyology, morphology and biology of Chionomys gud (Satunin, 1909) (Mammalia: Rodentia) in Turkey
    (UNIV ORADEA PUBL HOUSE, 2009) Sozen, Mustafa; Ozkurt, Sakir Onder; Karatas, Ahmet; Colak, Ercuement; Matur, Ferhat
    We examined the karyotype of Chionomys gud for the first time from Turkey, and found the values 2n=54, NF=58 and NFa=54. The X chromosome was found to be submetacentric and the Y chromosome acrocentric. Counts of embryos suggested a litter size range of 4 - 6 (mean 4.66, N = 3). Glans penis was stick shaped and covered by numerous microscopic papillae. The baculum had a well developed cartilaginous trifit distal process. The stalk of baculum had a well developed and broad base. The base and the shaft of the os baculum were roughly triangular in shape in dorsal view. The skull shapes of young, adult and aged specimens had distinctive features; in particular, the sagital crest became more prominent in older animals. Much variation was found in the shape of the molar chewing surfaces.
