“…terized by extensive intra-and interspecific karyotypic variation, probably due to their life histories and habitat preferences 33 . For this reason, they have become important biological models in chromosome evolution 16,34,35 , generating the first mate preference experiments using mammals that hybridized naturally with Spalax www.nature.com/scientificreports www.nature.com/scientificreports/ ehrenbergi 10 ; moreover, the early model for molecular characterization and analysis of hybrid zones was the pocket gopher [36][37][38][39] . One of the most fascinating cases is observed in Ctenomys species, which have 2n = 10 up to 2n = 70 15 .…”

Jorge c. pereira 5 , edivaldo Herculano corrêa de oliveira 6,7 , Malcolm A. ferguson-Smith 5 & thales Renato ochotorena de freitas 1,2,3 Reproductive compatibility usually decreases according to increasing genetic difference and the time of divergence between species. However, the amount of modification required to influence hybridization may vary in different species. Thus, it is extremely important to conduct studies that seek to understand what and how variables influence the reproductive isolation of species. We have explored a system involving two species of subterranean rodents that present morphological, karyotypic, and evolutionary history differences and are capable of generating hybrids. To gain insight into the karyotype organization of genus Ctenomys, we examined the chromosome evolution by classical and molecular cytogenetics of both parental species and hybrids. Furthermore, we have used different approaches to analyze the differences between the parental species and the hybrids, and determined the origin of the hybrids. The results of our work demonstrate unequivocally that some species that present extensive differences in chromosome organization, phenotype, evolutionary history, sperm morphology and genetic, which are usually associated with reproductive isolation, can generate natural hybrids. the results also demonstrate that females of both species are able to generate hybrids with males of the other species. In addition, the chromosome-specific probes prepared from Ctenomys flamarioni provide an invaluable tool for comparative cytogenetics in closely related species.

“…Gestation period lasts for about one month and they give birth to 3-4 new born annually. Remarks: The current taxonomic status of the blind mole rats in the Middle East and Turkey was revised by Arslan et al (2016) based chromosomal variation between species and populations of Spalax and Nannospalax. This review indicated the existence of 73 distinct chromosome races recorded in blind mole rats classified within the genus Nannospalax, along with the seven species recognized within the genus Spalax.…”

“…Within the traditional species classified in the Nannospalax genus, 25 races can be distinguished within N. leucodon, 28 races within N. xanthodon and 20 races within N. ehrenbergi. Karyotyping (2n) for the Jordanian specimens ranged between 60-62, whereas the NFa was 68-74, and NF 72-78 (Arslan et al;. Previous treatments of the species adopted the taxon S. leucodon (Nevo, 1969) and reported several chromosomal species in Palestine.…”

Distributional and ecological data were given to all rodents of Jordan. The rodent fauna of Jordan consists of 28 species with 20 genera in eight families (Cricetidae, Dipodidae, Gliridae, Hystricidae, Muridae, Myocastoridae, Sciuridae,and Spalacidae), including four introduced species.Keys for families and species were provided, along with diagnosis for each species and cranial illustrations for most species. Habitat preference and zoogeographic affinities of rodents in Jordan wereanalyzed, as well as their status and conservation.Threat categories and causes of threats on the rodents of Jordan were also analyzed. The distribution of rodents in Jordan represents a reflection of their global distribution ranges and habitat preferences. Species associated with the temperate forest of northern Jordan includes Sciurus anomalus and two wood mice, Apodemus mystacinus and A. flavicollis, while non-forested areas are represented by Nannospalax ehrenbergi and Microtus guentheri. Strict sand dwellers include Gerbillus cheesmani and G. gerbillus. Petrophiles associated with sandstone or black lava deserts are exemplified by Acomys russatus, A. r. lewsi, H. indica and S. calurus. Others including: Jaculus jaculus, G. nanus, G. henleyi, Meriones crassus, and M. libycus are all desert-adapted species with wider ranges of distribution where scarce vegetation, wadibeds, and marabs with clay, loess, or gravel surfaces provide foraging grounds and shelter. A single species, Gerbillus dasyurus, exhibits a wide range of distribution over diverse habitat types. The rodent fauna of Jordan consists of assemblages of different zoogeographical affinities. Nine, three, and seven were restricted or had most of its range within the Mediterranean, Irano-Turanian, and Saharo Arabian, respectively. Sciurus anomalus, Apodemus sp., Nannospalax ehrenbergi, and Microtus guentheri reached their most southern range of distribution in the Mediterranean regions of Jordan. The distribution of Gerbillus cheesmani extends from Asian deserts in India westwards into the Arabian Peninsula crossing Jordan as its most western range of distribution. Typical rodents of Saharo-Arabian affinities are represented by desert jerboas, gerbils, and jirds. North African species such as G. andersoni, G. gerbillus reached their most eastern distribution in southern Jordan. Both G. henleyi and G. nanus are widely-distributed species across North Africa reaching as far as India to the east, representing most northern outpost for these two species. Sekeetamys calurus is a nearly endemic to the Eastern Mediterranean region within southern Jordan and Sinai. Relicts are represented by Eliomys melanurus and Acomys russatus lewisi. Several threats affecting the rodent biodiversity in Jordan were identified including habitat loss and degradation, human disturbance and related activity, legislative and public awareness. The global conservation status of the rodents of Jordan according to the IUCN Red List include 22 species as least concern, one as near threa...

“…However, recent studies have recorded diploid chromosome numbers (2n) among mole rat populations of Turkey in range of 36-60. Accordingly, a new debate has been started for the taxonomy of this species which is already problematic because of morphological similarities (Arslan, Kryštufek, Matur, & Zima, 2016;Kankılıç, Kankılıç, Sözen, & Çolak, 2015;Sözen, Çolak, Sevindik, & Matur, 2013). These variabilities have also been seen on the structure and arms of chromosomes thereby directed the researchers toward the search for cytogenetic, molecular and morphological markers for the evaluation of emerging chromosomal forms.…”

In this study, the morphometric variations were investigated in Farmland and Hillside populations of subterranean rodent Nannospalax xanthodon from Central Anatolia. A total of 31 parameters were measured in the skull and mandible of 35 male individuals. Multivariate analysis (MVA) of the obtained cranial data was used to determine the parameters that varied between habitats and chromosomal populations (2n = 54 and 2n = 60). Furthermore, the effect of soil hardness on the morphology of the dorsal skull of male and female individuals was investigated. As a result, habitat differences caused some morphometric variations in the skull dorsal, especially facial bones, whereas the samples with diploid chromosome number 2n = 54 and 2n = 60 were separated by eight cranial parametric measurements. Accordingly, the known effect of ecological factors on phylogenetic variations in digging animals has first discussed in Nannospalax xantodon cytotypes.
