Communities with Galega orientalis Lam. in Kursk Region

. Plant communities dominated by the invasive species Galega orientalis, common in natural and anthropogenic habitats, have been identified in Kursk Region. On anthropogenic ecotopes (wastelands, roadsides), phytocoenoses of the ass. Galigetum orientalis are formed as a result of introduction of Galega orientalis into communities of the order Agropyretalia intermedio–repentis (class Artemisietea vulgaris). In natural habitats, Galega orientalis spreads in mesophylous meadow communities (order Arrhenatheretalia, class Molinio-Arrhenatheretea), while derivative communities Galega orientalis [Arrhenatheretalia] are formed. Galega orientalis is unevenly present in derivative communities, forming separate loci, as a result, its cover is less intensive than in anthropogenic communities. It may be due to a more intensive distribution of this species in disturbed habitats. Comparison of ranges of values of environmental factors showed that derivative communities are formed in wetter habitats. Phytocoenoses of the association are characterized by wider variation in values of acidity and richness of soils in mineral nitrogen.

Effect of fiber and energy in diet on productivity and formation of microbiocenosis in piglets

Today, an important role in the development of pig breeding is given to feeding animals, especially piglets during the transition from milk to vegetable feeding. This crucial period is associated with physiological characteristics of piglet growth and development. Therefore, the problem of developing mixed fodder that gives rise to high weight gain in piglets is relevant for pig farming. The experiments were conducted on piglets aged 15-42 days in Nadezhda farm, Kursk region. The purpose of the research was to increase productivity and form the microbiocenosis in the intestines of piglets. During the study period, barley-wheat mixed fodder was used with additional ingredients: feed fat, alfalfa grass flour and probiotic. Feed fats provide an optimal level of energy for piglets growth. The active substances of alfalfa flour are involved in all metabolic processes in the body, making it effective. Probiotic increases availability and digestibility of feed nutrients. The studies proved that the new composition of SK-3 increased the average daily weight gain by 20.5 %, the gross formation per piglet increased to 21 %. At the same time, survival of animals in the period 15-42 days increased to 100 %. The greatest growth of beneficial intestinal microflora from 107 to 109 CFU/g of feces was observed after feeding experimental piglets with mixed fodder containing grass flour, feed fats and probiotic by day 42. In comparison with the control animals, experimental animals showed a decrease in E. coli - from 107 to 104. The importance of using such ingredients as alfalfa grass flour, feed fats and probiotic in mixed fodder for piglets of 15-42 days of age was revealed. The relevance of the development of new mixed fodder was justified.

Promising directions for the development of the forest sector in a sparsely wooded region

Most researchers of the problems and prospects of the forest sector focus their attention on issues related to the concept of sustainable development. Sparsely wooded regions of Russia face a lot of obstacles, which makes the search for promising directions for the development of the forest sector in these regions with an active role of state support urgent. The work investigates the forest sector of Kursk region: the main problems and trends observed in its forest sector are noted, the key features of its forest resources are discussed. The directions for the development of the forest sector in the region and the related tasks of state support are formulated. All proposals are based on an orientation towards stimulating the use of local wood raw materials in those types of regional industries that are least demanding on the quality of raw materials. The following is proposed: (a) development of elements of “forest-oriented” environmental legislation; (b) regulatory support of demand for local renewable energy sources through diversification of heat supply to social infrastructure facilities; (c) setting quotas for the share of local wood raw materials consumed by enterprises.

DYNAMICS AND STRUCTURE OF CONGENITAL MALFORMATIONS AND HEREDITARY DISEASES IN NEWBORNS OF KURSK REGION

The article presents analysis of congenital malformations and hereditary diseases in newborns of Kursk region from the position of public health. Methodology of work includes retrospective analytical study of screening lists and discharge records in case-histories of the Regional perinatal center of Kursk; content-analysis of medical-statistical reports of the medical-genetic consulting center of Kursk regional clinical hospital. In the result of the study there were detected trends in main congenital pathologies of newborns in Kursk region during the years 2015-2019, as well as structure of birth defects by localization. The most prevalent congenital malformations in newborns in Kursk region were cardiovascular pathology, urinary system anomalies, chromosome diseases and central nervous system anomalies. Factors detected as associated with congenital malformations in newborns included low birth weight and living in rural area. The results of the study are applicable for the development of public health programs aimed at improvement of preventive services and organization of medical care for children with birth defects.

Influence of the peculiarities of using typical chernozem of the Kursk region on the molecular weight composition of labile humus substances

polydisperse compounds. Under the influence of agricultural use, the dispersion of LHS increases, and the molecular weight composition of LHS is trans-formed towards the accumulation of fractions with lower molecular weights in their composition. As a result, the number average molecular weight of LHS decreases from 15230 amu. in LHS virgin chernozem up to 11180-12770 amu. near LHS chernozem under permanent crops and fallow. The replacement of permanent steam with a deposit does not fundamentally affect the degree of dispersion of LHS and the values of the molecular weights of the fractions. There is only a tendency towards an increase in the relative content of fractions with high molecular weights. This is reflected in the value of the average molecular mass of LHS, which increased from 11180 amu in the variant with permanent vapor to 12530 amu. LHS has deposits.

The comparative fishery characteristics of water bodies based on a complex of morphometric, hydrochemical, hydrobiological and ichthyological indicators are presented. The question of the potential use of this group of water bodies for pasture aquaculture is considered based on the results of their bonitirovochnoy assessment for a number of fish-breeding indicators.

DEVELOPMENT OF A CROWDSOURCING INTERNET PORTAL FOR THE DETECTION AND CONTROL OF THE NUMBER OF RARE AND ENDANGERED PLANT SPECIES IN THE URBAN ECOSYSTEM ON THE EXAMPLE OF KURSK

Currently, at least 10% of plant species and even more animals are threatened with extinction on the planet Earth. The rate of extinction of species is 50-100 times higher than the natural rate. This trend has continued over the past 20-25 years. There are 439 endangered species in the Kursk region. Of these, 160 species of fauna, 265 species of plants and 14 species of fungi. The problem of conservation of rare and endangered plant species can be solved by their timely detection, subsequent monitoring and protection in specific habitats. Based on this, the purpose of this study is to develop tools for creating the most complete databases of rare and endangered plant species in urban ecosystems based on crowdsourcing methods and modern information technologies. At the initial stage of the implementation of projects for the conservation of biodiversity, the main difficulty lies in the mass identification of the presence of plant and animal species that are subject to protection on the territory of the city. It is possible to solve this problem using crowdsourcing methods. The team of the Southwestern State University has developed an Environmental crowdsourcing portal of the Kursk Region. This portal is designed on a modular basis, it includes various modules, including a module designed to solve the problem of biodiversity conservation. The module is developed using HTML5, CSS3, JavaScript, PHP and functions in user and administrator modes. Additionally, the functional blocks of thematic databases are designed using MySQL. Based on the database tables and the Yandex Maps API documentation, blocks for loading and displaying information on an interactive map have been developed. The module ensures the involvement of a wide range of urban population to identify the presence of plant and animal species that are subject to protection on the territory of the city. The module of the Environmental Crowdsourcing Portal of the Kursk Region considered in the article provides not only a solution to the problem of filling the database of rare and endangered species of plants and animals, but, like all crowdsourcing environmental projects, contributes to improving the level of environmental education of citizens, forming their consciousness and active life position.
