In this study, the 2n = 58 chromosomal race of blind mole rats,
Nannospalax xanthodon, from the Erzincan province in Turkey was investigated. Conventional chromosome staining, Ag-NOR staining and C-banding analysis were carried out in the specimens studied. The karyotype included three small or medium-sized meta/submetacentric pairs and twenty-five acrocentric pairs of autosomes of gradually diminishing size (NFa = 62). C-heterochromatin regions were found in centromeric and pericentromeric areas or in short arms of some bi-armed autosomal pairs and in pericentromeric areas of a few acrocentric autosomes. The X chromosome had a centromeric C-positive band and the short arm of the Y chromosome appeared to be C-positively stained. The NORs were
localized in distal heterochromatin areas of the short arms of two pairs of biarmed and one pair of acrocentric autosomes. Within the 58 chromosome populations reported from Turkey, two groups can be recognized differing by the presence or absence of a large submetacentric autosomal pair. The populations possessing this marker chromosome occur in central and northern Anatolia, whereas populations form eastern Anatolia have no similar chromosome in their karyotype.
Type populations of four fossil species of voles belonging to the genus Mimomys are redescribed. Mimomys ostramosensis is a large-sized, hypsodont Mimomys with enamel islet, Mimomys-ridge and relatively abundant cement. Mimomys tornensis, a medium-sized vole, is characterized by lack of typical Mimomys-ridge and islet present only in M3/, with very abundant cement accumulation. Mimomys pitymyoides, a medium-sized Mimomys, with broadly confluent triangles, is distinguished by the presence of islets and Mimomys-ridge in most specimens relatively low tracts and differentiation of enamel thickness not so distinct as in other Mimomys species. Mimomys pusillus is a small-sized vole with islet present only in younger wear stages, relatively frequent Mimomys-ridge and relatively low tracts.
The Academy Assembly, the highest body of the ASCR responsible for the topmost priority decisions related to the ASCR, held its XXXVIII Meeting on April 21, 2011. Among invited guests were Alena Gajdůšková, 1st Vice-President of the Senate of the Parliament of the Czech Republic, Stanislava Hronová and Vladimír Haasz, Vice-Chairpersons of the R&D Council and others. The main agenda item of this meeting was discussion the report of the Steering Committee of the Evaluation of Academy Institutes. Through the Committee's evaluation, the Academy Council is provided a full report of the research effectiveness of Academy Institutes. and ověřili Jan Zima, Jaroslav Pánek.
