Invasive non-native insect species are well-known threat to both local and introduced plant species in Europe. With increasing global trade and effects of climate change it is expected these alien species will continue to expand their distribution areas. One such non-native species is azalea sawfly Nematus lipovskyi Smith, 1974 (Hymenoptera: Tenthredinidae) that feeds on deciduous Rhododendron spp. This species is known to occur in the USA and was found in the Czech Republic for the first time in Europe in 2010. We report the first findings of this species in Latvia that were made based of field observations in the period of 2018-2020. The current known status of the species in Latvia is presented. Our observations of damage caused by sawfly larvae are summarized. Host plants used by sawfly larvae are listed – we note Rhododendron albrechtii as a host plant of this species for the first time. The possible pathways of its introduction and the overall importance of our findings in context with other non-native species expansions are briefly discussed.

It is proposed to identify the hierarchy of federal districts in terms of ecological opportunities for consolidation of vegetation cover according to three classes of soil cover according to the UN classification (grass + shrub + trees) on the land territory of Russia by ranking the shares of vegetation cover and human-modified lands, as well as ecological coefficients. The total ecological coefficient is calculated by dividing the share of vegetation by the total share of anthropogenic land. The forest-agricultural coefficient is convenient as the ratio of the forest area to the arable land area. The identification method revealed stable regularities of rank distributions in the form of trends and wave equations.

The aim of the work was to optimize the process of obtaining multicomponent protein compositions with high biological value and higher functional properties than the original vegetable protein products. Was realized studies to obtain biocomposites on the base of pea protein-oat protein and pea protein-rice protein. Developed composites were enriched with all limited amino acids. For each of the essential amino acids, the amino acid score was 100% and higher. Protein products used in these compositions are not in major allergen list, which allows to use these compositions in allergen-free products and specialized nutrition. To determine biosynthesis parameters for compositions from pea protein and various protein concentrates with the use of transglutaminase enzyme, was studied effect of concentration and exposition time on the amount of amino nitrogen released during the reaction. Decreasing of amino nitrogen in the medium indicated the occurrence of a protein synthesis reaction with the formation of new covalent bonds. Were determined optimal parameters of reaction: the hydromodule, the exposure time, the concentration of EP of the preparation, were obtained mathematical models. Studies on the functional properties of composites, the physicochemical properties of the proteins that make up their composition, and structural features will make it possible to determine the uses in the manufacture of food products based on their ability to bind fat, water, form foam, gels, and etc.

Identification of water-saturated zones in the tailings dams is an actual scientific and practical task in terms of providing, first of all, their mechanical strength and filtration stability. The prevention of accidents in tailings is complicated by the circumstance that the processes of increased filtration, appearing and developing in the dam body, are not fixed on the initial stages by visual and traditional methods. Insufficiency, from the point of view of data completeness, of networks of piezometric boreholes on tailings dams does not allow solving the tasks of necessary information hydrological support. At the same time, the use of active- sounding geophysical study methods allows obtaining sufficiently detailed information about the peculiarities of the internal structure of the tailings dam and the degree of water saturation of the composing soils. A reasoned choice of geophysical methods, as well as their combination, allows increasing the level and reliability of obtained data at subsurface studies. The paper presents the results of in-situ experiments on the study of the tailings dam of the mining enterprise by different in nature wave GPR (georadar) and seismic methods. A comparative analysis of the conducted studies has allowed clarifying the internal structure and assessing the dam’s condition, paying special attention to the identification of local zones of increased water saturation and filtration. Based on the calculated correlation coefficient of electromagnetic and seismic wave velocity values, it was revealed that synchronization of geophysical surveys allows significantly increasing the reliability of in-situ determinations, as well as obtaining more reliable data. The results of the studies are the basis for predicting the most vulnerable places (zones) of a bulk ground hydraulic facility, as well as the localization of water-saturated areas in the body of the ground structures with greater reliability and performance.

Environmental burdens are currently a significant determinant ofenvironmental quality. The occurrence of montane environmental burdens affects the environmental quality at the local, regional and supraregional levels, mostly to a negative extent. Environmental pollution, due to montane environmental burdens is accompanied by a reduction in environmental quality in all spheres of anthropogenic existence. It is for this reason that the presented article studies the occurrence of montane environmental burdens and their impact on environmental quality in individual regions of the Slovak Republic. In the analyses Analytic Hierarchy Process a multi-criteria decision-making method based on values of the weights in terms of the principles of the Saaty matrix – a quantification of synergistic interactions of indicators. The study concentrates on selected comparative years 2008, 2012, 2017 and 2021 and includes a matrix of their elimination. The results present a categorization of montane environmental loads in the Slovak Republic into categories of the environmental load (from very low to very high) on the environmental quality. In the summary matrix of a comprehensive assessment of montane environmental loads, negative indicators (55.65%) prevails over positive ones (44.35%) with a total scoring ratio of 0.80, i.e. III. category, the average impact on environmental quality.

"Possible negative impacts on the environment during mining of feldspar deposits with open-pit and underground mine are defined. The main changes have been identified, which are as follows: air pollution, soil destructions, change of relief, a local decrease in groundwater level, pollution by sewage and waste. Destructions of the soil cover are fixed under the dumps of the quarry and in the path of the movement of quarry equipment. Through the development of a pit and dumps, the primary relief acquires significant changes and the action of forces caused primarily by gravity is activated, aimed at smoothing out negative and positive relief forms. An increase in the height difference from the dump ridge to the bottom of the quarry and the formation of a significant, pronounced depression of the relief redirects the surface runoff, increases its speed, and reduces infiltration into the soil. Mining development caused drainage of groundwater due to its release to the surface and evaporation. Air pollution has a bigger scale than other components of negative impacts. The main impact of mining activities is due to emissions of pollutants into the atmosphere as a result of blowing dust from the surface of dumps and emissions from quarry transport and their deposition on the soil and storage of industrial waste. The main pollutants are inorganic dust with content of SiO2 - 65-82% and Al2O3 - 11-21%. Separately, the article discusses the impact on the environment during multi-components deposits` exploitation, where feldspar concentrates are produced as by-products. Several deposits in Ukraine belong to the group: Bakhtyn (fluorite ores), Nosachivske (titanium-ilmenite ores), Perzhanske deposits of rare metals, Mazurivske (tantalum and niobium ores). Most of them are planned to be mined underground, which saves more land resources in comparison with open workings. The placement of mine shafts and industrial sites for their maintenance requires an area of about 30 hectares. All of them have a complex ore processing with the separation of several concentrates, which necessitates the use of flotation and other reagents. The development of such deposits involves the organization of tailings and circulating water supply of the processing plant."

The establishment of the state of the massif by a diagnosis on different forest plots is part of a project of monitoring and silvicultural management. The purpose of this study is to assess the health status of the Ouled Bechih forest. The methodology used was the visual assessment of the tree crown of the dominant species (i.e. Quercus suber and Quercus canariensis) according to the protocols DEPEFEU, DEPERIS and ICP Forests. These protocols were selected for adoption based on field observations and their applicability in record time. The results obtained indicate that the health status of the trees within the studied plots is declining. The DEPEFEU value index shows an average of 1.75 for Quercus suber and 2.6 for Quercus canariensis while the DEPERIS has an average level of 2.36 Q. suber in and 3.37 in Q. canariensis. ICP Forests has also contributed to providing clearer information on the consequences of this health situation by deducting an average visibility rate of 1.20 and 2.63; social status of 1.17 and 3.11 and competition of 1.11 and 2.49 for Q. suber and Q. canariensis respectively. In general, the health status of the tree crown is average and almost adapted to the environmental conditions. In contrast, the carrying capacity of biodiversity is low and needs to be improved.

On the peach species, Springold variety, research was conducted on the influence of the F414 biological product on some physiological indexes and processes carried out on the foliar level, the area of culture being characterized by an accentuated thermo-hydric stress during the summer. Photosynthetic gas exchange, foliar transpiration and stomatal conductance were determined with the portable LC PRO + apparatus, and the leaf water forms were determined gravimetrically, the results obtained being correlated with the meteorological data from the vegetation period. Applying the F414 to the Springold variety resulted in the formation of a pellicle on the surface of the leaves, which, together with the action of the thermo-hydric stress specific to the area, caused stomate closure, reduction of CO2 supply, photosynthesis values being considerably lower compared to the control variant. As for foliar transpiration, the F414 product had a positive effect, the pellicle formed on the surface of the leaves, reducing the amount of water lost to the foliage. The application of this product has positively influenced drought resistance of the Springold variety, the percentages of the bound water being higher (5.1%) compared to the control variant (3.96%).

The major objective of this research paper was to investigate the effect of enrichment with different oil sources on the egg quality traits in laying hens. A total of 300 one-day-old pullets were used. There were seven dietary treatments of 10 % diet of the following: soybean oil (SO), sunflower oil (SFO), canola oil (CO), flaxseed oil (FLO), fish oil (FO), a mix of fish oil and soya oil (SO+FO), and DHA algal biomass oil. Each treatment contained six replicates with seven birds each. Random samples of 10 eggs per treatment were used; making 70. The organoleptic parameters included tests on smell, taste, color, and texture. The results revealed that there were no significant differences between the eggs from hens fed the different dietary treatments in terms of the organoleptic parameters used. Flaxseed oil, Fish oil and a mixture of Soy oil +Fish oil can be efficiently used to enrich poultry eggs with n-3 PUFA. However, FLO and flaxseeds can be safely used to avoid the fishy smell of poultry products, if present upon reheating

A total of 300 one-day-old pullets were used. There were seven dietary treatments of 10 % diet of the following: soybean oil (SO), sunflower oil (SFO), canola oil (CO), flaxseed oil (FLO), fish oil (FO), a mix of fish oil and soya oil (SO+FO), and DHA algal biomass oil. Each treatment contained six replicates with seven birds each. Random samples of 10 eggs per treatment were used; making 70. The organoleptic parameters included tests on smell, taste, color, and texture. The results revealed that there were no significant differences between the eggs from hens fed the different dietary treatments in terms of the organoleptic parameters used.
