AbstractFor the first time, reconstruction was carried out and a comparative analysis of the evolution of the parameters of biological diversity (species richness, entropy, dominance index, measure of organization, etc.) of mammalian complexes of six mountain regions of Eurasia in the Late Pleistocene–Holocene was performed. It was shown that their...

AbstractThe ontogenetic spectrum registers the age states of plants and is a sensitive population-based indicator of environmental changes. This is a review of population-ontogenetic methods for studies of plant populations (cenopopulations) based on the ontogenetic spectra. New age indices—the youth index and the maturity index—are introduced. For...

AbstractA comparative analysis of the phenetic pool of mammalian populations has been performed on the basis of two groups of characters: odontological and craniological proper. In total, 1637 skulls belonging to seven species were analyzed. It is shown that the values of population parameters (the intrapopulation diversity, proportion of rare phen...

AbstractThyroid hormones (THs) are the most important regulators of coloration ontogeny in teleosts. It has been shown experimentally that alterations in the hormonal status due to prolonged treatment with a biologically active form of THs, triiodothyronine, causes changes in the development of adult pigment patterns in bilaterally symmetrical Amat...

AbstractA procedure for dividing species into ecogeographic units (EGUs) and ecogeographic aggregations (EGAs) identified according to data on habitat gradients and distinctive features of migration (gene flows) is discussed. It is noted that every EGU or EGA can be regarded as a unit of reserves, reproduction, exploitation, or protection.

AbstractResponses of the mammalian population (Micromammalia and game species) to the technogenic transformation of natural landscapes in different regions of Yakutia are studied. It is established that game species are mainly affected by direct persecution, and the transformation of the population of small mammals depends primarily on the intensit...

AbstractThe development stability has been assessed (by the magnitude of the fluctuating asymmetry of craniological traits) with the change in the number of the Korean field mouse Apodemus peninsulae in Mongolia. It has been shown that an increase in the abundance of this species is not accompanied by a violation of developmental stability, but occ...

Abstract—This article considers the problem of the integrity of biological systems in adverse conditions. Based on the results of original studies, analysis has been performed of the reactions of structures at various levels of organization of plant items to extreme conditions of the Far North from the standpoint of changes in the density of their ...

AbstractThe stability of development (in terms of the fluctuating asymmetry of leaf measurements) was studied in populations of the silver birch Betula pendula from different parts of the range under varying degrees of anthropogenic impact (under the influence of industrial facilities in the territory of Khakassia and the Belgorod region and in the...
