Abstract. Recreational areas contribute considerably to the establishment of sustainable and comfortable urban environment. Green stands and soils of recreational areas provide important environmental functions and ecosystem services, their utilization depends on natural and anthropogenic factors distinguished by land-use history. For the case of the recreational areas of New Moscow, a comparative analysis of trees (n=1909) and soils (n=39, 0-10 cm layer) of the parks, established on former forested and fallow lands, was performed. It was shown that the species diversity was higher although the tree condition score was lower in the forest-parks, compared to the parks established on former fallow lands, which were generally characterized by a higher level of maintenance. Soils of these parks had a neutral pHH20 (7.20.8) and high content of organic matter (8.52.5 %), whereas the forest-parks soils were similar to the natural Retisols of the forest area with pHH20 6.40.2 and 5.10.2, organic matter content 5.90.2 и 3.50.2 %, respectively. Soils of the parks, established on the former fallow lands, had also a higher pollution level by particular heavy metals as well as considering the integral pollution index. Thus, a higher level of maintenance of the parks established on former fallow lands coincided with a higher anthropogenic pressure and ecosystem alteration. However, reorganization of forests into forestparks allowed partial preservation of the natural ecosystems. That is necessary to consider for planning the new urbanized areas in Moscow.

Formation and reproduction of gut microbiome begins at birth, while change in its composition depends mainly on various genetic, nutritional and environmental factors. The article considers the features of clinical manifestation of subcompensated intestinal dysbiosis in cats in assessing the effectiveness of its treatment. The studies were carried out on the basis of Department of Veterinary Medicine, RUDN University, and the clinical work was conducted at private veterinary clinics: Avettura, Epiona, In the World with Animals. Cats were selected for the experiment as they arrived at the initial appointment at veterinary clinics. The diagnosis of suspected intestinal dysbacteriosis was made considering anamnesis, clinical examination, and microbiological tests. The severity of intestinal dysbacteriosis was assessed on the results of clinical and laboratory studies. During the research, clinical and diagnostic approaches for subcompensated intestinal dysbacteriosis in cats were improved. Furthermore, effective ways of its treatment were developed. For subcompensated intestinal dysbacteriosis, administration of Lactobifadol probiotic, Vetelakt prebiotic and Azoksivet immunomodulator showed the greatest therapeutic effect, which led to an overall clinical improvement in 5.50 days. Therapeutic efficacy of B3 regimen was also clearly evidenced by the positive changes in intestinal microbiota and hematological blood parameters during the pharmacorrection. Improvement of clinical diagnostic approaches, prognosis of intestinal dysbiosis of varying severity and treatment effectiveness in cats require will allow to study intestinal dysbiotic disorders in other animal species.
肠道微生物组的形成和繁殖始于出生，而其组成的变化主要取决于各种遗传、营养和环境因素。在评估其治疗效果时，本文考虑了猫亚代偿性肠道生态失调的临床表现特点。这些研究是在RUDN大学兽医系的基础上进行的，临床工作是在私人兽医诊所进行的：Avettura、Epiona、In The World with Animals。猫在到达兽医诊所的最初预约时被选中进行实验。根据病史、临床检查和微生物检查，对疑似肠道菌群失调进行诊断。根据临床和实验室研究结果评估肠道菌群失调的严重程度。在研究过程中，猫亚代偿性肠道菌群失调的临床和诊断方法得到了改进。此外，还开发了有效的治疗方法。对于亚代偿性肠道菌群失调，给予乳双歧杆菌益生菌、Vetelakt益生元和Azoksivet免疫调节剂显示出最大的治疗效果，这导致5.50天内的总体临床改善。用药期间肠道微生物群和血液学参数的积极变化也清楚地证明了B3方案的疗效。猫的临床诊断方法、不同严重程度的肠道功能障碍的预后和治疗效果的改善将有助于研究其他动物物种的肠道功能障碍。

To improve the efficiency of ruminal digestion, researchers have developed a variety of enzyme feed additives. We are also working to find feed additives that improve the nutrition of rumen microflora, that is, prebiotics. For this purpose, we have proposed an animal protein hydrolyzate. The paper presents data reflecting the dynamics of hematological and biochemical parameters of blood serum of calves at the age of 3-4 months when hydrolyzed mink carcasses are included in the diet at doses of 5, 10 and 20 grams per head per day for 30 days. It was shown that after the completion of the experiment in animals treated with hydrolyzate at doses of 10 and 20 grams per head, there was a significant decrease in the content of leukocytes within the reference values and an increase in the percentage of lymphocytes in the leukogram. The change in the biochemical parameters of the groups of experimental bulls was characterized by a dose-dependent statistically significant increase in the concentration of protein, urea and reserve alkalinity. The concentration of total bilirubin, ALT, LDH significantly decreased, AST- increased. The results obtained indicate an increase in the immune reactivity of the animal organism with the use of the feed additive.

The methods of risk assessment and decision-making in the management of agrotechnology were studied in order to develop a methodical approach to assessing the risks of possible yield losses in case of deviations from the project parameters in the implementation of agrotechnology. The study uses methods of analyzing information from the subject area of risk management in the management of agricultural technology. A registry of possible deviations in the design values of process parameters in the implementation of agricultural technologies has been compiled. A new approach has been developed to assess the risks of possible yield losses in the implementation of agrotechnology with deviations in process parameters from project values. Using the proposed approach will provide an automated ranking of options for decisions on the degree of risk of possible crop failure in case of deviations from the designed values, which will facilitate the transition to intelligent management of crop production.

Microelements play a vital role in the maintenance and intensification of metabolic and regulatory processes in the body of animals. For a more complete study of provision of body of highly productive animals with microelements and diagnosis of metabolic disorders, especially under anthropogenic load, it is necessary to conduct biochemical blood tests. The article presents the results of studies on the content of trace elements (iron, copper, zinc, manganese) in the whole blood of cows from two farms in the Voronezh region, one of which (farm 2) is located in an area with increased technogenic load. In whole blood, the content of iron, copper, zinc, and manganese was determined by atomic absorption using a Shimadzu AA-6300 spectrophotometer. Samples were prepared by wet ashing at elevated pressure in a MARS-5 microwave system. Blood samples were taken 2 weeks before calving, one week and one month after calving. A reduced level of copper and zinc was found in animals from both farms throughout the entire study period. The dependence of the content of microelements on the physiological state of animals (before and after calving) was not revealed. It was shown that the content of iron in the blood of highly productive cows from farm 2 was lower throughout the study, and manganese - a week and a month after calving. The amount of manganese in blood of farm 2 animals was less than the lower limit of the physiological norm, while in farm 1 animals its concentration was within the reference normal range.

The stresses that arise during routine animal husbandry procedures, such as milking, shearing, weighing, loading and hoof care, are an actual problem in animal husbandry. The components of economic damage under stress are a decrease in overall resistance and productivity, deterioration in product quality, an increase in labor costs and funds per unit of production, an increase in animal morbidity and mortality. The studies were carried out on the basis of Belozernoe farm in the Salsky district, the Rostov region. A complex of clinical and laboratory studies was performed on 18 sheep (10 Romanov and 8 Tsigay breeds) aged 2 to 3 years, before and after a planned routine shearing. Stress in sheep caused by planned shearing was clinically manifested by general depression, in some cases, subfebrile fever, moderate tachypnea and tachycardia. It was shown that stress was accompanied by anemia, the development of erythropenia and leukopenia. Immunocompetent cells in the blood of experimental animals during stress development were analyzed. Severe lymphocytopenia was found to occur after a haircut. In addition, in the blood of experimental animals under stress, a tendency to a decrease in T-total cells was noted, which was accompanied by an increase in 0-cells, which was significant in sheep of the Tsigay breed (p0.05). When analyzing the main immunoregulatory T cells in sheep under stress, a significant increase in T-suppressors was revealed with a relatively stable level of T-helpers in the blood studied. Thus, a significant (p0.05) increase in the level of T-suppressors in sheep of Romanov and Tsigay breeds was recorded; it was by 1.15 and 1.19 times higher compared with the initial data. It should be noted that we did not find any significant differences between animals of Romanov and Tsigay breeds in stress development after shearing. The obtained data should be taken into account in the further search for methods of stress correction in sheep.

Species of Primula genus are indispensable introducents for the Kola North, characterized by compact bushes, bright colors, tolerance to urban environments and predominantly early flowering. The Polar-Alpine Botanical Garden-Institute has been studying species of Primula genus since 1934. The results of introduction studies (from 1948 to present) of 6 Far Eastern species of Primula genus: P. borealis Duby, P. farinosa L., P. jesoana Miq., P. nutans Georgi, P. patens (Turcz.) E. Busch, P. saxatilis Kom. were analyzed in the article. The initial material was obtained by seed exchange with botanical gardens in Russia, the CIS and foreign countries. Phenological observations were carried out according to generally accepted methods, on the basis of which the phenological spectrum of seasonal development of plants were constructed, and survival points (SP) were assessed. The introduction coefficient (IC) was calculated, which reflected the introduction value of the considered group of plants. The method of ecological-geographical analysis was used to compile the introduction forecast. Among the studied species, Primula nutans (SP=11) obtained from the seeds of cultivated plants from Scandinavian countries and P. jesoana (SP=9) were most adapted to the conditions of the Kola Arctic. Two species ( P. borealis, P. patens (SP = 4)) were poorly adapted to the conditions of the region, P. farinosa (SP = 1.0) and P. saxatilis (SP = 1.5) were not tested enough due to a short study period. The study showed that plants living from the tundra to the steppe zone ( P. nutans - I C = 1.57) and, in some cases, plants of the taiga zone reaching the subalpine belt in the mountains ( Primula jesoana - I C= 1.28) were adapted to local conditions. The plants of the tundra zone and the alpine zone in the mountains ( P. borealis - IC = 0.57) were less adapted.
报春花属的物种是科拉北部不可缺少的引进植物，其特点是紧凑的灌木，鲜艳的颜色，对城市环境的耐受性，主要是早开花。极地高山植物园研究所自1934年以来一直在研究报春花属的物种。远东报春花属6种(P. borealis Duby, P. farinosa L.， P. jesoana Miq.)引种研究结果(1948年至今)。， P. nutans Georgi, P. patens(土耳其)E. Busch, P. saxatilis Kom。进行了分析。最初的材料是通过与俄罗斯、独联体和外国植物园的种子交换获得的。采用普遍采用的物候观测方法，在此基础上构建植物季节发育物候谱，评估植物的生存点(SP)。通过计算引种系数(IC)来反映考虑的植物群的引种价值。采用生态-地理分析的方法编制了引言预测。在研究物种中，来自斯堪的纳维亚国家栽培植物种子的报春花(Primula nutans) (SP=11)和P. jesoana (SP=9)最适应科拉北极的环境。两种(P. borealis, P. patens, SP = 4)对该地区环境的适应性较差，P. farinosa (SP = 1.0)和P. saxatilis (SP = 1.5)由于研究时间短，检测不足。研究表明，从冻土带到草原带的植物(P. nutans - I C= 1.57)和从针叶林带到山区亚高山带的植物(Primula jesoana - I C= 1.28)在某些情况下适应了当地的条件。山地冻土带和高寒带植物(P. borealis - IC = 0.57)的适应性较差。

Highly productive animals, which are characterized by a more intense metabolism and regulation of the neurohumoral system, are more sensitive to a pool of adverse environmental conditions and can often be accompanied by metabolic disorders, a decrease in the immunobiological status of the macroorganism, reproductive function disorders and the development of pathological processes of various etiology and localization. The studies were carried out in the conditions of a large dairy complex in the Voronezh region located 25 km from a chemical plant for the production of mineral fertilizers: ammonia, ammonium nitrate, nitric acid. Its total emissions to the environment are 5316.5 tons per year, including 4480.3 tons of gases. Studies have been carried out to study the effectiveness of the use of Аminoseleferon-B to correct the immune status of highly productive cows in an immunodeficient state, under conditions of technogenic environmental stress. It was established that Аminoseleferon-B contributed to the activation of humoral and cellular links of nonspecific immunity, the reduction of birth and postpartum pathology, the increase in the effectiveness of treatment, and the improvement of reproductive function.

Improper use of pasture lands has become one of the factors resulted in destruction of natural vegetation. In order to stop desertification, forest reclamation works were carried out in the Caspian region in the mid-20th century, and significant areas of Krascheninnikovia ceratoides (L.) plantings were created. The Pamirian winterfat is a wide distributed plant. It has a well-developed root system, providing sufficient water in climatic conditions of the arid zone. The article provides a systematic assessment of the long-term impact of afforestation and the development of a subshrub layer in various humidity conditions over the growing season during the functioning of pasture ecosystems in reclaimed Molodezhny-teresken territory. The main taxation indicators used to assess the development of Krascheninnikovia ceratoides were determined: height, crown diameter, plant standing density. The research was based on field taxational and morphological measurements of the subshrub and calculations of the complex indicator D. The study revealed that the generalized analysis of the biometric parameters of Pamirian winterfat according to criterion D was an objective tool for assessing its development in the prevailing climatic factors of a certain year. A direct correlation was established between the amount of precipitation in autumn period of research years and the values of the integral indicator D (r = 0.97) with its higher value in 2012 (D = 0.905). There is a high level of direct correlation between the values of the integral indicator D and the yield of feed mass (r = 0.90). Krascheninnikovia ceratoides reclamation and forage plantations have stability, durability, high price-forming potential and are the best way to improve and restore pastures in arid and semi-arid zones.

The organic dormancy of Ceratonia seeds is associated with their water resistance, which means that Carob suffers from difficulty in natural regeneration. Before planting Carob seeds must be treated in order to disturb mechanical dormancy. The main reasons for the decline in genus Ceratonia L. are anthropogenic impact on natural ecosystems, as well as the uses of Ceratonia for many goals. This problem is aggravated by the fact that seedlings of Ceratonia in nature are very rare because of organic dormancy, and the distribution of carob occurs mainly with the help of seeds. The aim of this work was to study the methods of pre-sowing treatment of dormant Carob seeds. This study was conducted on a wild Carob genotype grown in Syria. Four different pre-sowing treatments were the following: soaking in boiling distilled water (70 С) for 10 min; soaking in boiling distilled water (70 С) for 10 min + soaking in distilled water for 24 h; acid scarification with sulphuric acid (H2SO4); acid scarification with sulphuric acid (H2SO4) + soaking in distilled water for 24 h. We applied and examined for their effectiveness stimulation of Carob seed germination. The results showed that seeds treated with sulphuric acid (H2SO4) and then soaked in distilled water for 24 h was the most effective method increasing the germination percentage by 98 % compared to untreated seeds 5 %.
