Abstract

The fauna of nematodes of the PetrSU Botanic Garden’s rocky pinery is investigated for the first time. 43 species of soil nematodes are revealed. These are representatives of 6 functional groups (bacteriotrophes, micotrophes, politrophes, predators, obligate and optional plant parasites). In general, the fauna of nematodes of the present biocenosis can be estimated as rather various (Shannon’s variability index H’ = 3.8). Specific diversity of the fauna of nematodes, availability of representatives of various trophic-ecological groups in nematodes’ communities are indicative of the little disturbed stability in the conditions of their habitat.

Abstract

Purpose: The aim of this article is to present the processes of economic security of the Penitentiary system of the Russian Federation. Design/Methodology/Approach: Research methodology is based on the works of world known scientists (specialists in the sphere of penitentiary production, law and administration), systematic approach and dialectic method. Authors used a wide information base that consists of legislation and statistics of the Russian Federation. Findings: Authors justified separate spheres, within which the abstract isolated control functions of the prison industry are to be implemented (finance, personnel, technology). Authors analyzed the prerequisites of the Penitentiary system's economic security provision. For this reason, several significant problems that have the character of contradictions were determined. Practical Implications: The research results may be implemented into Russian legal and socioeconomic framework to improve and increase the penitentiary systems's economic security. Originality/Value: The main contribution of this study is the highlighted interconnections between Russia's economic security and the development of the Russian Penitentiary system's production sector., peer-reviewed

15. [Tendencies of nematodes communities to recover after soil cover degradation].

Abstract

The way nematodes form communities on a new substrate after complete soil and plant cover degradation is studied on a model of industrial dumping. It is revealed that recovery of soil cover after degradation begins with invasion of mainly the upper soil horizon by nematodes. At the early stages, species that are resistant to unfavorable environmental conditions dominate (bacteriophages), next the abundances of carnivores and nematodes that are connected with plants increase, which indicates the process of biocenosis regeneration.

Abstract

Nematode community structure of the potato fields with different infection levels of potato cyst-forming nematode (PCN) such as 10, 30 and 214 cysts per 100 g of soil has been investigated. The influence of specialized parasite on nematode fauna and dominance character of different ecological-trophic groups were described. Parasitic nematode genera in natural meadow biocenosis and agrocenoses without PCN are Paratylenchus, Tylenchorhynchus, and Helicotylenchus. It is established, that Paratylenchus nanus was the prevalent species among plant parasites at low infection level. Larvae of Globodera prevailed in the soil with middle and high infection levels and substituted individuals of other genera of parasitic nematodes. The fact of increase in number of hyphal-feeding nematode Aphelenchus avenae was revealed.

Abstract

Studies were carried out of karyotypes of Anguina sp. parasitic on four species of wild cereals and two species of sedge. The number of chromosomes in fissing genital cells was found to be n=9 for A. graminophila and n=18 for A. agrostis. Anguina sp. injuring sedge have the haploid number of chromosomes n=18.
