During the past four decades, chromosomal twin species Microtus arvalis sensu stricto Pallas, 1779 (2 n = 46) and M. rossiaemeridionalis Ognev, 1924 (2 n = 54) have been the focus of attention of zoologists, evolutionists, and ecologists. Phylogenetic relationships between them remain unclear in many aspects, because the independence of these species(More)
A highly inbred, long-term selected for low fitness strain LA of Drosophila melanogaster posesses a significant mutational load and unusually high rates of spontaneous mutability as revealed by CyL/Pm method. Our results indicate that during cross of CyL/Pm to LA strains, destabilization of copia-like and mobile elements and induction of H-E hybrid(More)
The problem of the geoantineutrino deficit and the experimental results of the interaction of uranium dioxide and carbide with iron-nickel and silica-alumina melts at high pressure (510 GPа) and temperature (16002200 C) have induced us to consider the possible consequences of made by V. Anisichkin and A. Ershov supposition that there is an actinoid shell on(More)
Comparison of the current approaches to human ecology shows a contradiction between certain views on the subject and the methodology of its analysis. The notion of human ecology as the ecology of the species Homo sapiens is being developed in terms of modern general ecology and should be considered at all organizational levels, from individual to global.(More)
The functional role of differentiation with respect to local population density, expression of responses to the presence of other individuals, and body weight has been analyzed from an ecoenergetic standpoint with consideration of known mathematical laws. The results indicate that increased variation in these parameters (i.e., their higher diversity)(More)
The functional properties of the invasive Heracleum sosnowskyi were compared with those of the native Heracleum sibiricum. The leaf and root traits, as well as those of a whole plant and of the mycorrhiza formation, were studied. H. sosnowskyi can fulfill the high-productivity potential only under the optimum availability of resources (especially water),(More)
Bone remains of birds from a location of the middle Subboreal period and from three locations of the early Subatlantic period were studied on the Ustyurt plateau (Kazakhstan). Three out of 17 avian species that have been identified (Phalacrocorax pygmaeus, Falco peregrinus, and Nyctea scandiaca) proved to be absent in the modern fauna of the region. Our(More)
The Central Asian high-mountain or rock voles of the genus Alticola Blanford, 1881 are one of the least studied groups of rodents. Taxonomic status of various geographic forms is not yet established until our days. This genus is not enough examined by biochemical and molecular genetic methods. We analyzed morphological disparity among rock voles of the(More)
The genetic diversity of the Uralian moose population and the role of the Ural region in the phylogeographic structure of the European moose were evaluated based on sequence polymorphisms of the mtDNA control region. The nucleotide diversity of the Ural moose was low, whereas haplotype diversity was rather high. It was found that the haplotype pool of the(More)
