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)
Collections made in the course of long-term field studies on ecology of the northern mole vole Ellobius talpinus Pall. in the Ural Region and neighboring areas (more than 2000 individuals from 24 points of the species range) were used to analyze geographic variation in its coat color (color morphs). On the basis of long-term observations (1985–1999) on(More)
An adequate model for studying the basic processes in adaptation of a species to new abiotic and biotic environments is the muskrat (Ondatra zibethicus L.) acclimatization in Eurasia. The muskrat acclimatiza tion may be regarded as an analog of geographic for mation, and the rate and efficiency of the initial microevolutionary stages may be estimated(More)
Morphometric parameters of hepatocytes have been studied in five small mammal species with different ecological specificity from two taxonomic groups: a surface-dwelling insectivore (the common shrew, Sorex araneus), a subterranean insectivore (the European mole, Talpa europaea), surface-dwelling rodents (the bank vole, Myodes glareolus and herb field(More)
The muskrat (Ondatra zibethicus L.) allochronic samples at different stages of its introduction in Western Siberia are compared by geometric morphometrics; the comparison demonstrates directed changes in the size and shape of mandible as well as the changes in its morphological and functional characteristics as a feeding organ. As is shown, a rapid initial(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)
