    Karyological studies of the 2n=60 cytotype of Nannospalax nehringi from Central Anatolia
    (Univ Florence Botany Inst, 2013) Baydemir, Nursel Asan; Yagci, Tuba; Cakir, Sukran
    In this study, the G-bands and nucleolus organizer regions (NORs) of the 2n = 60 chromosomal form of Nannospalax nehringi from Central Anatolia (Konya) are presented. The karyotype possesses nine pairs of submetacentric and subtelosentrics and 20 pairs of acrocentric autosomes gradually decreasing in size (fundamental number = 80 and autosomal fundamental number = 76). NORs were localized in the telomeric regions of the short arms of three large pairs and one medium-sized pair of subtelocentric autosomes (nos. 1, 3, 4, 9).

    Karyotype and hair scale structure of Nannospalax leucodon (Nordmann, 1840) from central Anatolia (Rodentia : Spalacidae)
    (Tubitak Scientific & Technical Research Council Turkey, 2008) Asan, Nursel; Yagci, Tuba
    The karyotype and hair scale structure of the subterranean mole rat, Nannospalax leucodon (Nordmann, 1840), in Kirikkale province were determined. The diploid number, fundamental number, and the number of autosomal arms were 54, 74, and 70, respectively. The structure of the hair scale type was examined with a scanning electron microscope (SEM) and was found to be serrate coronal, simple coronal, and erose coronal at the base, shaft, and tip, respectively. The chromosomal form and hair scale structure of the mole rat were recorded for the first time from Kirikkale province.

    Karyotypic studies of Meriones dahli Shidlovsky, 1962 (Rodentia: Muridae) from Turkey
    (Univ Florence Botany Inst, 2011) Baydemir, Nursel Asan; Demirbas, Yasin; Pamukoglu, Nahit; Albayrak, Irfan; Yagci, Tuba
    In this study, conventionally stained, C- and Ag-NOR banded karyotypes of Dahl's jird, Meriones dahli, were reported from Turkey. The species had a karyotype of 2n=50, NFa=74 and NF=78. The X and Y chromosomes were submetacentrics in all specimens examined. Blocks of constitutive heterochromatin were located in the pericentromeric areas of autosomes including the X and Y chromosomes. Interstitial C- bands are also detected in the long arms of one of the largest acrocentric pairs. Nucleolar organizer regions (NORs) were located at the telomeric regions of the short arms of three submetacentrics and two acrocentrics.

    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.
