Description
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region

Description
By the methods of classical histology and modern histochemistry in differential assessment of various albuminous components, we have revealed a number of new regularities of age dynamics and distribution of some albumen in cells and tissues of musky preputial glands of muskrat males inhabiting under conditions of Baikal region ecosystem

Description
Researches were spent in the conditions of the branch of FGBOU VPO «Orenburg State Agrarian University » of the Ilek zoo technical school and on the chair of noncontagious illnesses of animals at Orenburg State Agrarian University. The absolute and relative growth of the weight of a pancreas in ontogenesis was studied. All facts are subjected a statistical processing and during development the absolute and relative growth of the weight is established

A NEW METHOD OF THE RAGWEED INHIBITION (AMBROSIA ARTEMI-SIIFOLIA L.) OF SOUTH RUSSIA
DescriptionAdventive weeds control using classical approach of biological protection against adventive species is not always satisfactory. A new method of the ragweed inhibition is developed that is based on shifting of the natural phenological stage of the phytophage growth. It makes possible to produce a large group of ragweed noctuidae under laboratory conditions on an artificial nutrient medium and to inundate weed infested areas with them by the time of the invader emergence

MOLECULAR-GENETICS BASE OF APPLE SELF-INCOMPATIBILITY
DescriptionEstimation of self-incompatibility allelic diversity in Russian apple varieties was conducted. We have established S-allele gene set for a number of varieties. The most common allele of gene was identified. Alleles frequency data obtained are consistent with those in the world apple germplasm
