Chromosomal evolution of the Genus Nannospalax (Palmer 1903) (Rodentia, Muridae) from western Turkey

“…Which factor causes these rearrangements is still not conclusively known. On the other hand, recently published molecular studies (Krystufek et al, 2011;Hadid et al, 2012;Kandemir et al, 2012) showed that differentiation of chromosomal races of blind mole rats in Anatolia was already done and each chromosomal race might be a good candidate to be a separate species. However, more detailed molecular studies using techniques such as genome analysis and mtDNA are still required.…”

“…According to our parsimony tree results, N. xanthodon grouped polyphyletically, because the 2n = 56Tr (N. leucodon) grouped together with an Anatolian sample (N. xanthodon). Kandemir et al (2012) investigated the phylogeny of Turkish blind mole rats using molecular tools. They found similar tree topology.…”

“…Currently more than 30 chromosomal races have been determined in Turkish blind mole rats but there is still doubt about the taxonomy of this taxon (Nevo et al, 1994;Sözen et al, 1998aSözen et al, , 1998bSözen et al, , 1999Sözen et al, , 2000aSözen et al, , 2000bSözen et al, , 2006aSözen et al, , 2006bSözen et al, , 2011Sözen, 2004;Matur and Sözen, 2005;Kankiliç et al, 2007;Ivanitskaya et al, 2008;Arslan et al, 2011). Kandemir et al (2012) discussed the taxonomic name problem of blind mole rats and so here we will follow Kandemir et al (2012). Ivanitskaya and Nevo (1998) analyzed Jordanian blind mole rats using C-, G-, and AgNOR-banding techniques and compared these data with previous results obtained in Turkish and Israeli blind mole rats.…”

Revised classification design of the Anatolian species of Nannospalax (Rodentia: Spalacidae) using RFLP analysis

“…Currently, in light of all the information that we know about Turkish mole rats, it can easily be seen that the taxonomic status of Turkish mole rat species and subspecies remains uncertain as some cytotypes have genetic differences on the species level (Nevo et al, 1995;Arslan et al, 2010;Kandemir et al, 2012). Therefore, the validity of the taxonomic status of all species and subspecies previously described from Turkey should be investigated to form a foundation for understanding taxonomic relationships.…”

“…Only a limited number of genetic studies have been carried out on Turkish mole rat cytotypes. Phylogenetic studies using data from allozymes (Nevo et al, 1995), randomly amplified polymorphic DNA (Kankılıç et al, 2013), mitochondrial sequences (Arslan et al, 2010;Hadid et al, 2012;Kandemir et al, 2012;Kryštufek et al, 2012), and cytogenetics (Ivanitskaya et al, 2008;Arslan et al 2011) have been conducted in an attempt to understand relationships within Nannospalax. These molecular studies with limited cytotype sampling supported the monophyly of the genus and recognized 4 major clades (vasvarii, leucodon, xanthodon, and ehrenbergi) (Hadid et al, 2012).…”
