Description
Complicated compost with organic and mineral components, has a serious impact on the physical, chemical and biological properties of topsoil significantly modifies its cycles of elements and substances; with the Carboniferous and up to now it has been established the supremacy of the recovery processes in landscapes as compared to oxidation processes through the introduction of complicated compost in their stabilizing factors

THE ROLE OF SCIENTIFIC ILLUSTRATION IN THE HISTORY OF BIOLOGY
DescriptionIllustration is an important part of scientific work and educational process. They help us understand studying material and see the different connection among things. The different types of illustration were analyzed and we also demonstrated illustrations in scientific world, education materials and the role of abstraction in scientific illustration

Description
The author describes the dynamics of commercial catches and the forecasts of pikeperch catch in 2010- 2016 with an analysis of the causes that affect the state of stocks. The analysis of the effectiveness of the recommended pikeperch catch has been made taking into account the factors that affected the fishery. Researches were carried out to study the population structure, seasonal distribution, migrations and other characteristics of the pikeperch populations in the Azov limans. The obtained data made it possible to assess the state of the pikeperch stocks and give recommendations on their rational use. Based on the results of ichthyological studies, the pikeperch age, length and weight composition have been determined and its biological state has been studied. The preliminary forecast of the stocks and the recommended pikeperch catch in the Azov limans for 2018 is given. The forecast of the recommended pikeperch catch in the Azov limans for 2018 is based on the analysis of the stocks of commercial fish species for a number of years of observations, taking into account the total mortality rate under the influence of the fishery load (commercial mortality coefficient) and the amount of replenishment of commercial population with fish mature for the first time

RESOURCE POTENTIAL IN LUTEOLIN-7- GLYCOSIDE VERONICA INCANA (SCROPHULARIACEAE) IN CENTRAL YAKUTIA
DescriptionThe article reveals luteolin-7-glucoside accumulation in the overground part of Veronica incana L. It assesses resource potential of V. incana depending on the phytocenotic conditions of coenopopulations growing in Central Yakutia. Collection of the material was carried out during V. incana flowering in 7 coenopopulations and in the collection of the Yakut Botanical Garden. Analysis of flavonoids content was performed by HPLC method. The high levels of flavonoids content in the biomass of generative plants marked in coenopopulations that are in optimal conditions, and the lowest - in coenopopulations experiencing strong anthropogenic influence. In addition, one of the factors reducing the content of flavonoids in plants is low light intensity in habitat. The highest resource potential on the luteolin-7- glucoside observed in biomass V. incana, growing in fescue grassland steppe and culture

Description
The article presents the results of the research of the generative function of the testis of the Rattus norvegicus Albinus after seven-day adaptation to low temperatures. We revealed the adaptation induced spermatogenesis disorders in the rat testis. The observed changes may be induced by the general adaptation syndrome
