    Contributions to the karyology and distribution areas of cytotypes of nannospalax leucodon (Rodentia: Spalacidae) in western anatolia

    Mole rats of the genus Nannospalax having high karyotypic variability (chromosome numbers ranging from 2n = 36 to 2n = 62) are dominant mammals occupying the subterranean niche in Anatolia. Respective distributional ranges of karyotypic forms within this taxon remain uncertain due to insufficient data. In the present study, karyological analyses of 36 specimens belonging to N. nehringi were examined from 10 sampling sites of Western Turkey. During the study, five karyotypic forms were recorded (2n = 36 NF = 68 from Aydin, 2n = 40 NF = 72 from Isparta, 2n = 56 NF = 72 from Usak, 2n = 60 NF = 78 from Isparta and 2n = 60 NF = 84 from Denizli and Burdur). When distribution areas of karyotipic forms are considered, these karyotypes are new records for this taxon in Turkey. In addition, this study aims to determine the most likely distribution areas of the four chromosome forms (2n = 36, 40, 56, 60) in Turkey paying attention on previously verified localities data.

    Determination of genetic variations in the genus Dryomys Thomas, 1906 (Rodentia: Gliridae) distributed in Turkey using NADH dehydrogenase 1 (ND1) gene
    (Taylor & Francıs Ltd, 2018) Kankılıç, Teoman; Seçkinozan Şeker, Perinçek; Erdik, Arif Can; Kankılıç, Tolga; Selvi, Engin; Yiğit, Nuri; Çolak, Ercüment
    Genetic diversity and phylogeny of Dryomys nitedula and Dryomys laniger from Turkey was described in the present study by using mitochondrial DNA NADH dehydrogenase 1 gene (ND1). Genetic variation in ND1 gene was determined by two model-based phylogenetic analyses and a network analysis revealed 27 haplotypes of D. nitedula constructing four main lineages (Thrace, Anatolia, North-eastern Anatolia and Savsat) that have non-overlapping geographic distributions and no shared haplotypes, but on the other hand, three haplotypes were detected in four samples of D. laniger from Turkey. It was determined that nucleotide diversity was low but haplotype diversity was high in D. laniger, whereas, D. nitedula has both high level of haplotype and nucleotide diversity. Characterization of Thrace lineage of D. nitedula with low nucleotide diversity and determination of the total nucleotide diversity of Anatolian lineages (Anatolia + North-eastern Anatolia + Savsat) to be approximately four times higher than that of Thrace lineage indicated that Anatolia may have served as a refuge for D. nitedula. Divergence times and high level of nucleotide differences between D. nitedula lineages showed that diversification of the lineages may have occurred before and during ice ages in Turkey, thought to be a refuge for post-glacial colonization and biodiversity resource of Europe. Additionally, estimated divergence times and calculated genetic distances yielded compatible results with the previous paleontological and genomic data for the diversification time of two species in the genus.

    Phylogenetic inference from 16S rRNA gene sequencing in chromosome races of the genus nannospalax species (Rodentia: Spalacidae)
    (Pleiades Publishing, 2024) Kankılıç, Teoman; Çelikbilek, Habibe Didem; Kankılıç, Tolga; Seçkinozan Şeker, Perinçek; Selvi, Engin; Civelek, İlkay
    In this study, we aimed to develop a species-level phylogeny for the Nannospalax genus, identify cryptic species that are difficult to differentiate using standard methods, and further evaluate the relationships across chromosomal forms of several species. 16S rRNA gene sequences from 81 Turkish regions were evaluated and statistical analyzes were conducted. Results are as follows; (i) Nannospalax cilicicus was found to be monophyletic and sister in relation to Nannospalax xanthodon; (ii) We suggested for the first time that the Central-Anatolian populations should be classified under the species name Nannospalax cilicicus (stat. n.); (iii) the unidentified 2n = 52 cytotypes from Bolu and Nannospalax leucodon cytotypes were reciprocally monophyletic, these data support the notion that the 2n = 52 cytotypes from Bolu belong to an unidentified taxon; (iv) study also offered evidence for the monophyly of N.
