Phylogenetic analysis of supraspecies relationships in one of the most young and species rich group of myomorph rodents - subfamily Arvicolinae was carried out on the base of two nuclear genes. Results have shown that mole-voles - Ellobiusini, steppe voles - (Lagurini) and grey voles (Arvicolini) are sister groups. This divergence is the most late, third(More)
It is rather difficult to construct a system of gray voles of the tribe Microtini by a set of morphological and karyological characters because form generation is mosaic at these organization levels. The sequence of the mitochondrial cytochrome b gene was used to study the phylogenetic relationships and taxonomic position of the Central Asian subgenus(More)
The results of the first molecular study focused on the phylogenetic position of the Gansu mole, Scapanulus oweni are presented. The analysis based on sequences of the mitochondrial cytb gene and five nuclear genes supports the monophyly of the Scalopini tribe including S. oweni and shows that two highly fossorial talpid tribes, Talpini and Scalopini, are(More)
The Northern mole vole E. talpinus, despite its wide distribution, is characterized by a stable karyotype (2n = NF = 54) and slight morphological polymorphism. We made a preliminary analysis of a mitochondrial DNA fragment to clarify the level of genetic variation and differentiation of E. talpinus The complete cytochrome b gene (cyt b, 1143 bp) and a short(More)
119 Toaddheaded agamas (Phrynocephalus) is an essenn tial element of arid biotopes throughout the vast area spanning the countries of Middle East and Central Asia. They constitute one of the most diverse genera of the agama family (Agamidae), variously estimated to comprise 26 to 40 species [1]. The subgeneric Phrynoo cephalus taxonomy is poorly studied:(More)
257 Modern views on the phylogeny and systematics of Asian moles are based on the morphology of their skull, teeth, and postcranial skeleton. However, because of rather scanty data often limited by individd ual specimens from several localities, the taxonomy of East Asian Talpidae is poorly developed. In addition, the use of the odontologic evidence for the(More)
Three different chromosomal forms of striped hamsters that belong to the superspecies complex Cricetulus barabensis sensu lato (Cricetidae, Rodentia), namely, “barabensis”, “pseudogeiseus”, and “griseus”, were studied to determine their relationships based on different biological and genetic species concepts and using the morphological, karyomorphs,(More)
The taxonomy of striped hamsters from the supraspecies complex Cricetulus barabensis sensu lato (Rodentia, Cricetidae) is still controversial. The morphological and genetic differences between them are insufficient. In laboratory hybridization experiments, we obtained F1 and F2 hybrids from different combinations of mating between three chromosomal races.(More)
We propose an optimization-based theoretical approach to tailor the optical response of silver/silica multilayer nanospheres over the visible spectrum. We show that the structure that provides the largest cross-section per volume/mass, averaged over a wide frequency range, is the silver coated silica sphere. We also show how properly chosen mixture of(More)
