The article presents the role and the place of soil beetles (Coleoptera: Carabidae, Scarabaeidae, Elateridae, Tenebrionidae) - pests of agricultural crops in agro-ecosystems and their study, collection, identification of species composition and distribution of the plants in the Republic of Dagestan
The article reflects influences of soil conditions on growing types of wood vegetation. The carried-out chemical analyses show quantity of chemical elements which have to arrive to the soil with tree waste, and also acidity of the soil
In this article we present data on the effect of addition
of mineral nutrition elements in the structure of the
phytoplankton community in the north-eastern part of
the Black Sea in the different seasons. Experimental
studies have shown that the increase in biomass of
microalgae occurs at the simultaneous addition of
nitrogen and phosphorus in the accumulative cultures.
In the spring can get biomass Emiliania huxleyi,
P.pseudodelicatissima, Chaetoceros curvisetus and
Skeletonema costatum, in the summer – E. huxleyi, C.
curvisetus, P.pseudodelicatissima, S.costatum,
Thalassionema nitzschioides, Leptocylindrus danicus,
Dactyliosolen fragilissimus, Proboscia alata,
Pseudosolenia calcar-avis, in the autumn - C.
curvisetus, S.costatum, Th. nitzschioides, L. danicus,

The expression of nine candidate genes for
QTL abdominal fat weight and relative abdominal fat content was investigated by real-time polymerase chain reaction (PCR) in the liver, adipose tissue, colon, muscle, pituitary gland and brain of broilers. The high mobility group AT hook1 (HMG1A) gene was up-regulated in liver with aratio of means of 2,90 (P≤0,01) in the «fatty» group (relative abdominal fat content 3,5±0.18%, abdominal fat weight 35,4±6,09 g) relative to the «lean» group (relative abdominal fat content 1,9±0,56%, abdominal fat weight 19,2±5,06 g). Expression of this gene was highly correlated with the relative abdominal fat content (0,70, P≤0,01) and abdominal fat weight (0,70, P≤0,01). The peroxisomeproliferator-activated receptor gamma (PPARG) gene was also up-regulated in the liver with a ratio of means of 3,34(P≤0,01) in the «fatty» group relative to the «lean» group. Correlation of its expression was significant with both the relative abdominal fat content (0,55, P≤0,05) and the abdominal fat weight (0,57, P≤0,01). These data obtained and the data of references will allow the statement that the HMG1A, PPARG and FABP2 genes were candidate genes for abdominal fat deposition in chickens. Searching of rSNPs in regulatory regions of thesegenes could provide a tool for gene-assisted selection
The article considers turban cucumber forms, we have also described the origin of this characteristic, briefly overviewed turban forms in species of the family of Cucurbitaceae. We have given the agro-botanical iconography of this trait in pumpkin cultures for cucumis. In Europe, China and America turbanoformis cucumber forms are used as a vegetable, there are some varieties. It is shown that turbanoformis forms are found in the fruit of the cucumber with hermaphrodite flower, polunina ovaries, short or shareplace the melon, and also in forms with the ongoing evolutionary process
Surface sewer depends on vegetable cover. Deleting the
vegetable cover (due to cutting, overindulgent fall out
live-stock, fires), wrong plowing up of surfaces (along
declivity) and processing of ground without observance
agronomic rules bring reinforcement of erosions, local
soil washout, origin gully erosions and to increase the
turbidities of the rivers
With biotechnology development, working out and introduction of the new technologies focused on an intensification of a complex of difficult biochemical transformations which proceed in meat raw materials by manufacture smoked sausages became possible.
One of such ways is introduction of starting cultures in a compounding of sausages. In this article we have presented the researches of perspective microbial strain and the choice of the strain for creation of starting cultures
The authors propose to consider alien invasive species
as new bioresources. These plants form powerful
(usually single-species) thickets in the secondary range
and their size are larger than at the native cenosis. The
territory occupied by invasive species, especially in
disturbed habitats, is quite high, so their possible yield
is very high. The main problem of using alien species
in the pharmacological purposes is the lack of
information about the dynamics of the chemicals
accumulation. Available data on the biochemistry in its
natural habitat is inadaptable for the same taxon in the
secondary range because of significant
microevolutionary changes. In this work we present
the results of phytochemical screening four legume
species, formed invasive populations in the Middle
Russia - Galega orientalis Lam., Lupinus polyphyllus
Lindl., Robinia pseudoacacia L. & Caragana
arborescens Lam. Information about these species as
traditional medicine plants is given. Original data on
the concentration phenolic compounds and biophile
silicon in leaves and inflorescences are presented.
Information on the fractional composition of the
flavonoid complex is done. Taking into consideration
the high adaptability of invasive species, the chemical
analysis of the samples from different ecotypes was
made. It is shown that accumulation of bioactive
agents & biophile silicon isn’t depended on the
environmental conditions. Concentrations of
polyphenolic compounds were at the average level in
comparison with medicinal plants. Thus, the
combination of flavonoid complex with biophile
silicon provides pharmacological significance of
studied species, and justifies the needing the further study of invasive plant species in order to create new
herbal medicines
Adventive 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
The results of biological recultivation of disturbed lands are offered in the article. Silvicultural and taxation parameters of basic wood types of dumps and their role in stable ecosystem formation are presented
