The assessment of the groundwater resource sustainability in the European part of RussiaAbstract
This article presents a method to assess the resistance of groundwater resources to anthropogenic impact and the fresh groundwater withdrawal as well as the results of such assessment for different territories of the country ranging from a federal district or a region to an artesian basin. The assessment was carried out with the help of the system of indicators and indexes of groundwater resource sustainability under the influence of groundwater withdrawal developed by the author.
CHPP related anthropogenic impact zonesAbstract
This article offers a concept of an integral CHPP related anthropogenic impact zone (AIZ), representing a complex of industrial units, organizations and communications, which support the life cycle of a CHPP. The author conducted an analysis of the basic features of an integral CHPP AIZ and its elements. This concept may have a certain theoretical significance in solving optimizing environmental problems at the level of individual territories and the country in whole.

The geochronology of the Holocene vegetation deve¬lopment in the South-east Baltic region (based on the results of a paleogeographic study)Abstract
This article presents the results a of complex palaeogeographical study of Velikoye peat bog (the Šešupė River basin, the Kaliningrad region). The pollen analysis accompanied by radiocarbon dating, makes it possible to reconstruct the vegetation development, on the basis of which the climate changes in the South-east Baltic region over the Atlantic-Subatlantic periods of the Holocene can be tracked.
The identification of the predominant age of the crystalline basement of continental and ocean platformsAbstract
This article presents the evidence of the ancient origin of crystalline basement of the platform areas of the Earth developed as a result of global volcanism in the Hadean (more than 4 Ga). In the late Mesozoic-early Cenozoic, another outbreak of volcanism and dehydration of subsoils led to a significant subsidence (8—10 km) of continental masses and the formation of the World Ocean.

The development of ideas about the formation of Arctic sea fauna and its biogeographical connectionsAbstract
The author arrives at a conclusion on the vast biogeographical connections of the Arctic, Atlantic and Pacific faunas in the Phanerozoic faunas on the basis of the comparative analysis of modern and ancient communities of invertebrates and the changes in their habitats.
The species composition and the biotopical groups of the gastropoda in the pond of KaliningradAbstract
This article considers the species composition, species biotopic distribution, nutrition, and zoogeographic characteristics of gastropoda in Kaliningrad ponds. The author shows the interplay of ecological factors that determine the species composition of molluscs. The article also presents the data on the impact of the invasive species Potamopyrgus antipodarum (Gray, 1843) on the malacofauna of water bodies.
СA comparative analysis of bioflavonoid accumulation by Trifolium pratense in the Kaliningrad regionAbstract
This article examines the influence of environmental factors on the polyphenol accumulation of the red clover (Trifolium pratense L.) in the coastal and continental areas of the Kaliningrad region. The influence of temperature, light, and mineral nutrition factors on the accumulation activity of anthocyanins, leucoanthocyanidins, and catechins is determined. The coastal and continental area plants did not show any significant differences in the content of the examined polyphenol classes.
On the causes of the extinction of black saxaul in the East Karakum and its impacts on the ecology and the economy of the desertAbstract
The cause of the extinction of the Black saxaul in the East Karakum is established on the basis of the analysis of literature and experimental data collected over the last 100 years.
The steroid regulation of immune memoryAbstract
The solution to the problem of immune memory generation in pathological processes of various kinds is a subject of theoretical investigations of the biomedical science. The role of immune memory in different diseases is ambiguous and may have both positive and negative consequences. It necessitates the search for effective ways of its regulation (by either endocrine or external influence), which, in some cases (infectious and tumourous disease), aim to strengthen and, in other cases (autoimmune diseases and allergy), to suppress (weaken) the immune processes. The factors affecting the formation of immunological memory are numerous and varied. The steroid hormones are considered the most abundant group of biologically active agents. The influence of these agents on proliferation, differentiation and apoptosis of immune system cells is being intensively studied. This review analyses the data on the role of steroid hormones in the immune memory regulation obtained in the recent researches.
The features of the chemical composition of integumentary loams in the Vaytka-Kama loess provinceAbstract
This article presents the chemical analysis of integumentary loams in the eluvial landscapes of the Vyatka-Kama Cis-Ural region. The authors focus on the features of microcell migration and the composition of petrogenic oxides. The inheritance of the microcell dispersion features of integumentary loam from the bedding rock was established on the basis of statistics.
