“…This led to interspecific variability in the chromosomal distribution and number of copies of repeats. The result of the present work tested previously mentioned hypotheses on the particular lability of the arvicoline sex chromosomes in relation to C-band www.nature.com/scientificreports/ modification 60 and also suggests a significant heterogeneity of the heterochromatic regions of the X chromosomes of voles [46][47][48][49][50]60 .…”

“…C-banding of the chromosomes of most of the species used in the study was previously performed [46][47][48][49][50] . Here, in addition to T. savii, we carried out C-banding of chromosomes of six more species of voles (A. mujanensis, Alticola tuvinicus, Blanfordimys juldaschi, M. dogramacii, T. daghestanicus, and T. majori), which allowed to visualise not only centromeric, but interstitial heterochromatic blocks on X chromosomes of four of these species-A.…”

euchromatic segments of the X chromosomes of placental mammals are the most conservative elements of the karyotype, only rarely subjected to either inter-or intrachromosomal rearrangements. Here, using microdissection-derived set of region-specific probes of Terricola savii we detailed the evolutionary rearrangements found in X chromosomes in 20 vole species (Arvicolinae, Rodentia). We show that the evolution of X chromosomes in this taxon was accompanied by multiple para-and pericentric inversions and centromere shifts. the contribution of intrachromosomal rearrangements to the karyotype evolution of Arvicolinae species was approximately equivalent in both the separate autosomal conserved segments and the X chromosomes. intrachromosmal rearrangements and structural reorganization of the X chromosomes was likely accompanied by an accumulation, distribution, and evolution of repeated sequences.

“…The moderate support (bp = 72) could be due to the underrepresentation of the former taxon with only one available sequence, thus until more data can be included the specific rank of M. i. karamani is uncertain . However, recent studies showed a much wider distribution of the latter than originally thought (Taurus Mt., Turkey; Kryštufek et al, ), as it is now found in Armenia (Golenishchev et al, ; Zorenko et al, ), eastern Iran (Mahmoudi et al, ), western and southwestern Turkey (Arslan, Toyran, Gözütok, Yorulmaz, & Zima, ; Yiğit et al, , ), and Lebanon (Kryštufek, Abi‐Said, & Hladnik, ).…”

The social vole of Cyrenaica, Libya, is the only extant representative of the Cricetidae family found in Africa. Its taxonomic status has been under debate, partly due to the problematic systematics of the entire group of social voles and partly due to the lack of morphological and molecular data from Cyrenaican specimens. In this study, we applied ancient DNA protocols to produce three cytochrome b (cytb) sequences of Cyrenaican voles and built a phylogenetic reconstruction (195 sequences in total) incorporating all available cytb sequences of the remaining social voles, other representatives of the genus Microtus and closely related cricetids. We used this phylogeny to test the performance of the model‐based, single‐locus, species delimitation approach implemented in mPTP and delimited nine species of social voles. Among them are the Cyrenaican vole, Microtus mustersi and its sister species M. guentheri, distributed along the Mediterranean coasts of southwestern Asia. Biogeographical reconstruction of ancestral area and molecular clock estimations of the time since the divergence of the two sister lineages suggest that their common ancestor dispersed into Africa through a coastal route and was isolated in Cyrenaica as a result of population fragmentation associated with Middle Pleistocenic pluvial/interpluvial cycles. Geographic isolation triggered the speciation process, but species distribution modeling gave evidence of subsequent niche divergence; M. guentheri has adapted to the xeric conditions of its distributional area, while M. mustersi benefited from the milder Cyrenaican climate. The Cyrenaican vole is a relict species more than 200,000 years old, has a small and isolated distribution and probably merits conservation.

“…It is very difficult to morphologically distinguish the Microtus, which is represented by 65 species, from each other (Musser and Carleton, 1993;Jaarola et al, 2004). However, they are frequently used in comparative cytotaxonomy studies since they differ from each other in terms of diploid chromosome numbers (2n=17-62) despite their morphological similarities (Zima and Král, 1984;Modi, 1987;Zagorodnyuk, 1990;Lemskaya et al, 2010) Turkey (Jaarola et al, 2004;Kryštufek and Vohralik, 2005;Kryštufek et al, 2012;Arslan et al, 2016;Selçuk and Kefelioğlu, 2018;Demirtaş and Gürler, 2019). These species distributed in Turkey are classified in three main groups as 'pine voles', 'social voles' and 'arvalis group' (Kryštufek and Vohralik, 2005).…”

Conventionally stained and C-banded karyotypes of Guenther's vole (Microtus guentheri), Major's pine vole (Microtus majori) and Common vole (Microtus arvalis) were studied from Turkey. Diploid chromosome numbers of M. guentheri, M. arvalis and M. majori were found as 2n=54 and NFa=52, 2n=46 and NFa=68 and 2n=54 and NFa=56, respectively. All chromosomes of M. guentheri were pericentromeric C-band. In Microtus arvalis (obscurus cytotype) and Microtus majori karyotypes, autosomal chromosomes were heterochromatin C band positive and negative band. In M. arvalis (obscurus cytotype), sex chromosome was C band negative. In this study, heterozygote chromosome was not found in the obtained autosomal chromosome set of M. arvalis. M. majori has enlarged heterochromatin block from centromere to telomere on the long arm of X chromosome. Y chromosome was completely heterochromatin. ÖZET Bu çalışmada, Güentheri tarla faresi (Microtus guentheri), Kısa kulaklı kır faresi (Microtus majori) ve Yaygın tarla faresi (Microtus arvalis) türlerinin standart karyotipleri ve kromozomların C-bant özellikleri belirlendi. M. guentheri türünün diploid kromozom sayısı (2n) = 54 ve otozomal kromozomların kol sayısı (NFa) = 52, M. arvalis (obscurus sitotip) türünün 2n = 46 ve NFa = 68, M.majori türünün 2n = 54 ve NFa = 56 şeklindedir. M. guentheri otozomal ve eşey kromozomlarda pericentromerik C-bant olduğu belirlendi. Microtus arvalis (obscurus sitotip) ve Microtus majori karyotiplerinde otozomal kromozomlar C bant pozitif ve negatif şeklindedir. M. arvalis türünde X ve Y kromozomu C bant negatif özelliktedir. M. majori karyotipinde X kromozomunun uzun kolunda sentromerden telomere doğru genişlemiş heterokromatin blok bulunmaktadır. Y kromozomu ise tamamen heterokromatindir.
