“…Identifying intra-specific variations is the most fundamental step in documenting biodiversity in a particular region. In this sense, the variations hidden in the genome of both plant and animal species in our country are tried to be revealed by using a wide variety of markers, including karyotype analysis [7,17,19,28,29]. Karyotype variations are an easy-to-apply method used to determine genetic variation.…”

The results of a cytogenetic study on some representatives of Gliridae from Turkey were introduced. The G-, C-, and AgNOR banded karyotypes of Muscardinus avellanarius abanticus from Abant (Bolu), and the G-banded karyotype of Myomimus roachi from Thrace were presented for the first time. Additionally, the G-banded karyotypes of Dryomys nitedula, and Myoxus glis were analysed. Because of not including a secondary constriction and the smallest chromosome being metacentric instead of acrocentric in the autosomal set, the karyotype of M. a. abanticus was different from that of M. a. trapezius. With the comparison of obtained G-banded patterns belonging to the other Glirid species, it was detected that obtained karyotypes displayed consistency at a great extent with the previously determined karyotypes.

“…Turkey blind mole rats have been represented by three species (N. xanthodon, N. ehrenbergi and N. leucodon). The differences in Anatolian blind mole rat karyotypes have been defined both between morphologically similar sibling species and distinct populations within each species (Arslan et al, 2011, Arslan et al, 2013, Kankılıç et al, 2017, Matur et al, 2013. In the Nannospalax ehrenbergi species, 12 different cytotypes were defined in terms of diploid chromosome numbers (2n = 48, 52, 54, 56, 58) and the number of autosomal arms (NFa = 62,64,68,70,72) (Coşkun et al, 2006, Ivanitskaya et al, 1997, Nevo et al, 1995, Yüksel, 1984, Yüksel and Gülkaç, 1990).…”

This study was conducted to explain the karyological analysis and morphological characteristics of blind mole rat samples collected from Ceyhan, Adana in Turkey. The chromosomes of the blind mole rat samples were stained and analysed using conventional methods. The chromosomes were defined according to centromere positions by processing photographs of metaphase cells. The karyotype of Nannospalax ehrenbergi showed 53 chromosomes (2n=53) and fundamental number of chromosomal arms NF=66 and the number of autosomal arms NFa= 62. The karyotype showed a hybrid individual. X and Y chromosomes were determined as metacentric and acrocentric, respectively. The autosomal set had 5 (+1 single homologous) pairs of metacentric/submetacentric and 20 pairs of acrocentric. Morphological studies were carried out on two male Nannospalax ehrenbergi skulls from Adana province. Lengths of three external (height, hindfoot length and weights (gr)) and 24 cranial morphological points on skulls were measured using an electronic caliper. This was the first study in which 2n=53 NF=66 population was determined from Ceyhan. This form was described as a hybrid form. The portion behind the palate (os palatinum) has no a sharply defined styloid process.

“…These vastly unusual rodents are represented by two genera: the greater BMR, Spalax (Guldenstaedt 1770), and the lesser BMR, Nannospalax (Palmer 1903). The latter represents an excellent research model for chromosomal speciation studies, as the genus Nannospalax includes 74 groups with fixed chromosomal differences [ 6 , 7 , 8 ] with a wide range of diploid chromosomal number (2 n ), from 36 to 60. These chromosomal forms (CFs) are alternatively labelled as cytotypes, races, or sibling/good biological/cryptic species [ 8 , 9 , 10 ].…”

A Cryptic Subterranean Mammal Species, the Lesser Blind Mole Rat (Nannospalax leucodon syrmiensis)—Retreated but Not Extinct

Blind mole rats (genus Nannospalax) attract a great deal of attention because of their cancer resistance and longevity. Due to the high rate of chromosome rearrangements, 74 Nannospalax chromosomal forms have been discovered. The convergence of their external morphology complicates their taxonomy, and many cryptic species remain unrecognized. Thus, the European N. leucodon supersp. is listed in the IUCN Red List of Threatened Species with “Data Deficient” status. It is crucial for the conservation of biodiversity to clarify its taxonomy, to recognize each cryptic species, and assign to them the correct conservation status. Of the more than 20 chromosomal forms described within N. leucodon, five cryptic species occur in Serbia. The most threatened among them—N. l. syrmiensis, described and named 50 years ago in the regions of Srem, Belgrade and Mačva—has been declared extinct in the literature, which may have negative consequences for the conservation of wildlife genetic diversity. Through five years of fieldwork and comparison of 16SrRNA and MT-CYTB gene segments between old, archived teeth and recently collected material, we show that N. l. syrmiensis is not extinct. However, its habitat has been fragmented and reduced, owing primarily to anthropogenic impact. Therefore, detailed surveillance, population-structure studies, risk assessment, and appropriate conservation measures are needed.
