The facts related to contamination of plants with pathogenic bacteria being a possible source of human foodborne intestinal diseases are discussed. Data bound up with influence of environment conditions with respect to attachment and penetration of bacteria in plant tissues are described. Exquisite results related to the rate of proliferation and the time of retaining enteropathogens in plant organisms are presented
As the result of the work, the test of microsatellite DNA markers for the identification of genomic polymorphism between apple cultivars Florina, Golden Delicious and clonal forms has been done. With the high level of intervarietal polymorphism, studied DNA markers showed no allelic differences between varieties and their clonal forms
The article contains the species composition of the four families of soil Coleoptera (ground beetles, scarab, beetles, darkling) marked for different agricultural crops of the Republic of Dagestan
The analysis of territorial protection of the vegetation of natural zones, separate geobotanical allotments (formations), unique vegetative associations and Red Data Book species of vascular plants of Yakutia is given in the article. The objects of vegetation kingdom that need urgent actions for their habitats’ protection are marked
The article presents the violation of water protection zones. The change in soil fertility. Transparency is linked to the nature of the coating beaches and surface destruction. Surface runoff depends on the vegetation cover. The destruction of vegetation (deforestation, excessive grazing, fire), incorrect plowing surface (along the slope) and tillage farming without following the rules lead to increased erosion, local soil erosion, gully erosion and the rise to an increase in turbidity of rivers. Environmental effectiveness of forest plantations. Prevention of pollution and siltation of river. Improving the sanitary condition of the territory
The article contains the results of the complex analysis of the upwelling at the Western coast of the Middle
Caspian in the summer of 2011, according to the data of observations, obtained with the use of contact and remote methods
The article presents the results of the comprehensive analysis of the main parameters of the health status of the population of Dagestan as the initial stage of the regional medical and ecological monitoring
The technology for the identification of Picea abies L. clones by using ISSR markers was developed. 9 ISSR primers ((GA)9T; (AC)8C; (CA)6RY; (CA)6RG; (CA)6(GT); (CA)6(AC); (AG)8T; (GA)8С и (AG)8YT) were recommended to use for genotypes detection. The selected primers have shown the high level of polymorphism. A total of 172 amplified fragments were found by the selected primers and 149 (86.6%) of them were polymorphic
Based on the information stored in the system of database management, biodiversity indices with special accent on measures of species richness are comparatively studied for Carabid beetles in various areas of the East Caucasus. Biodiversity indices are shown to be dependent on sampling or collecting techniques, sample size, geographic localization and its area
The historical and geographical information of peste des petits ruminants and the characteristics of its agent are given, also some epizootological features of the infection are described, and PPR specific prophylaxis and control measures are discussed
