    A Comparative Morphological and Karyological Study on Hedgehogs, Erinaceus concolor Martin, 1838 and Hemiechinus auritus (Gmelin, 1770) (Erinaceomorpha: Mammalia) in Diyarbakir Province
    (Kahramanmaras Sutcu Imam Univ, 2011) Uluturk, Servet; Coskun, Yuksel
    In this study, we examined the morphological and karyological characteristics of Hemiechinus auritus and Erinaceus concolor (4 male, 3 female) in Diyarbakir province. The karyotypes of E. concolor (2n = 48) and H. auritus (2n = 48) were found similar and but distinctly all the autosomal chromosomes of both species were determined to be biarmed in contrast to the some previously published accounts. There are obvious differences on the tooth roots that could be used in key to genera between Hemiechinus and Erinaceus are determined by the results of this study.

    Geographic variation in the skull morphology of Ellobius lutescens Thomas, 1897 (Mammalia: Rodentia) by geometric morphometric analyses
    (Senckenberg Gesellschaft Naturforschung, 2018) Kayal, Alaettin; Gharakhloo, Mohammad Moradi; Coskun, Yuksel
    In this study, we examined a total of 43 samples belonging to three Ellobius lutescens populations from Turkey, Iran and Nakhchivan, which are geographically separated by the Zagros, Tendurek and Alborz mountain ranges. We applied geometric morphometnc methods (GMMs) to explore the differences in size and shape of the cranium and mandible. Indeed, we intriguingly found that the populations differed in cranium but not mandible size Comparison of the Iranian and Turkish populations alone revealed morphological differences in the shape of the cranium and mandible that could be used as a barometer to predict the origin of individual animals. Importantly, our findings indicate that the Zagros and Tendurek mountain ranges may have acted as a barrier between these two populations, resulting in evolutionary divergence in these anatomical features. Consequently, we propose that within E. lutescens, subspecies including E. lutescens woosnami exists and in time, genetic, besides geographical barriers, may prevent subspecies from interbreeding with each other.

    Geographical distribution and karyotype of Nannospalax ehrenbergi (Nehring 1898) (Rodentia, Spalacidae) in Iraq
    (Firenze Univ Press, 2019) Hamad, Zaitoon Ahmed; Kaya, Alaettin; Coskun, Yuksel
    This paper concerns the karyological analysis of fourteen mole rats collected in four different localities of North-Iraq (Kurdistan Region). The result showed that they belong to the following cytotypes of Nannospalax ehrenbergi: Duhok-Bardarash Population 2n = 52, NF = 76, and NFa = 72 and Arbil-Sulaimania-Kirkuk populations 2n = 52, NF = 80 and NFa = 76. The karyotypes of the Duhok population are similar to those from Mosul, but the Arbil-Sulaimania-Kirkuk populations' karyotype represents a new chromosomal form. Their distribution extends from North Iraq to Sulaimania.

    Karyotype of Nannospalax ehrenbergi (Nehring 1898) (Rodentia: Spalacidae) in the Mosul Province, Iraq
    (Assoc Teriologica Italiana, 2012) Coskun, Yuksel; El Namee, Ausame; Kaya, Alaettin; Rahemo, Zohair I. F.
    The karyotypes of mole rats Nannospalax ehrenbergi (Nehring 1897) from two closely located populations from Mosul province, Iraq, were investigated. The karyotype of this form was 2n = 52, NF = 76, NFa = 72 which consists of 11 pairs of metacentric/submetacentric autosomes, and 14 pairs of acrocentric autosomes. The X chromosome was large and metacentric, whereas the Y chromosome was small and acrocentric. The species occurrence in Iraq, based on literature overview and the present study, was updated. Karyotypic data for the Nannospalax ehrenbergi from Iraq are presented for the first time.

    A new karyotype and chromosomal banding pattern in Nannospalax ehrenbergi (Nehring, 1898) (Rodentia: Spalacidae) from southeast Anatolia, Turkey
    (Firenze Univ Press, 2015) Coskun, Yuksel; Baydemir, Nursel Asan; Kayaa, Alaettin; Karoz, Ayse Merve
    This paper presents new data on chromosomes of the Palestine mole rat, Nannospalax ehrenbergi, from southeast Anatolia, Turkey. A new chromosomal form, 2n = 56, NF = 62 and NFa = 58, is determined from the region. C-banding revealed pericentromeric constitutive heterochromatin in one submetacentric and seven acrocentric autosome pairs. Two acrocentric autosome pairs and an acrocentric chromosome with a secondary constriction showed interstitial C-positive bands on their long arms. A secondary constriction was detected in the Y chromosome. The NORs were observed in one medium-sized metacentric autosome pair, and in four acrocentric pairs of autosomes.

    Nucleolar organizer region distribution in Nannospalax ehrenbergi (Nehring, 1898) (Rodentia: Spalacidae) from Iraq
    (Tubitak Scientific & Technological Research Council Turkey, 2014) Coskun, Yuksel; Baydemir, Nursel Asan; Kaya, Alaettin; Karoz, Ayse Merve
    The distribution of nucleolar organizer regions (NORs) in Nannospalax ehrenbergi from Iraq was determined for the first time. In the karyotype of N. ehrenbergi the diploid number, fundamental number, and fundamental autosomal number were 52, 76, and 72, respectively. NORs occur in the telomeric regions of submetacentric and acrocentric autosome pairs.

    Reproduction, postnatal development, and social behavior of Ellobius lutescens Thomas, 1897 (Mammalia: Rodentia) in captivity
    (Tubitak Scientific & Technological Research Council Turkey, 2015) Kaya, Alaettin; Coskun, Yuksel
    The reproduction, postnatal development, and social behaviors of the Transcaucasian mole vole (Ellobius lutescens) were studied in the laboratory in 2012/2013. The collected voles were kept in glass cages in captivity conditions and observations were made throughout the year. The litter size, gestation period, neonate weight, eye-opening, weaning, and earliest sexual maturity age were observed. Pups were born with 'nipple-seizing incisors'. These incisors were different from those of adults. The molars and normal incisor eruption appeared after 19-21 days. Females have three pairs of nipples. The adult females were bigger in size than the males, yet the males consumed more food than the females. Isolated individuals consumed more food than did the paired animals.

    Review of unique odd chromosome-numbered underground rodent species of the Palearctic region: Ellobius lutescens Thomas 1897 (Rodentia: Cricetidae)
    (Tubitak Scientific & Technological Research Council Turkey, 2016) Coskun, Yuksel
    A review of the species within the genus Ellobius from Turkey is provided. The Transcaucasian mole vole, Ellobius lutescens, is the westernmost representative of the genus and among the most enigmatic and yet most neglected of the Palearctic placental mammals. Currently, its distribution is thought to be restricted to eastern Anatolia. The Transcaucasian mole voles inhabit a wide variety of habitats across this distribution area in semiarid or grassland territories and high-elevation cultivated fields. The species' distribution, feeding ecology, population structure, behavior, reproduction, genetics, and fossil records are reviewed here for Turkey. This paper brings together information published during the last century in books and scientific papers. Future research needs to include collation of further data on population dynamics, maximum length of the breeding season, reliable abundance estimates, and studies of distribution and migration. Other areas worthy of investigation are the identification of wintering areas, acquisition of up-todate data on reproduction and mortality, and investigations into the consequences of environmental changes for the species.

    The tunnel structure of blind mole rats (genus Spalax) in Turkey
    (Taylor & Francis Ltd, 2010) Yagci, Tuba; Coskun, Yuksel; Asan, Nursel
    The structure of the tunnels and burrows of mole rats (genus Spalax) was examined in Central and Southeastern Anatolia in the years 2002-2009. There are two types of mounds: linear ones and scattered ones. While a one-layer tunnel structure is observed in nearly all parts of Turkey, we also found three-layer tunnels, which were made in soft and moist soil. The tunnels made in moist soil were deeper than the ones made in hard soil. We found that mole rats blend the soil with their urine and produce a sticky mud with a bad odour in order to strengthen the walls of the opened galleries.
