The white+ gene was used as a reporter to detect transcriptional silencer activity in the Drosophila genome. Changes in the spatial expression pattern of white were scored in the adult eye as nonuniform patterns of pigmentation. Thirty-six independent P[lacW] transposant lines were collected. These represent 12 distinct pigmentation patterns and probably 21(More)
Background: Exposure of macrophages to bacterial products such as lipopolysaccharide (LPS) results in activation of the NF-κB transcription factor, which orchestrates a gene expression programme that underpins the macrophage-dependent immune response. These changes include the induction or repression of a wide range of genes that regulate inflammation, cell(More)
Methods of geometric morphometrics have been used to compare the ranges and directions of geographic and technogenic forms of variation in the morphology of the mandible in Ural populations of pygmy wood mice (Sylvaemus uralensis Pall.) exposed to different types of pollutants (radionuclides, fluorides, and toxic petrochemical products). The range of(More)
Using geometric morphometric methods, coupled biotopic variation in the shape of the mandible was revealed in cenopopulations of two sympatric rodent species, the pygmy wood mouse (Sylvaemus uralensis Pall., 1811) and bank vole (Myodes glareolus Schreb., 1780), in the Southern Urals. As a rule, heterospecific pairs from syntopic samples synchronously taken(More)
Geometric morphometrics has been used to reveal coupled geographic variation in the mandible shape in two sympatric rodent species, the pygmy wood mouse (Sylvaemus uralensis Pall.) and bank vole (Myodes glareolus Pall.), in the Southern Urals. It has been shown that syntopic samples synchronously collected from the local communities of these species usually(More)
The ecological “compensation principle” enunciated by Yu.I. Chernov, who suggested a higher level of compensatory diversity in communities depleted in composition, proved to be also applicable to a single population, as demonstrated in a model rodent species, mole vole with mono- and polymorphic coat color, using the methods of geometric morphometrics. The(More)
It has been accepted for inclusion in Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia by an authorized administrator of DigitalCommons@University of Nebraska-Lincoln. Abstract The Central Asian high-mountain or rock voles of the genus Alticola Blanford, 1881 are one of the least studied groups of(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)
Methods of geometric morphometrics and population phenogenetics have been used to evaluate morphogenetic rearrangements in two sympatric species of Myodes voles (M. glareolus Schreb. 1780 and M. rutilus Pall. 1779) from syntopic populations recovering after exposure to local “ecological vacuum” created as a result of rodent extermination in a natural focus(More)
181 Siberian flying squirrel (Pteromys volans L., 1758) is the only representative of the subfamily Pteromyii nae, occurring on the territory of Northern Eurasia. The habitats of this species are confined to the forest area (mainly conifers, partly the foresttsteppe and forr estttundra zones). The range of this species covers the territory of Eurasia from(More)
