Grey mountain Caucasian bees are of great interest for the selection, as a valuable gene pool of different populations of this race is supported by high mountains and inaccessible gorges of Dagestan, while serving as an isolated mountainous natural breeding areas. The studies were conducted in three different climatic conditions of the republic: the plains, foothills and mountainous areas. In the area of natural dispersal of gray mountain Caucasian bees in Dagestan released several local populations and different backgrounds. Characteristics of the main morphological features of honey bees are the length of proboscis, wing and width of the third tergite and others. These features bees vary, depending on the habitat population. Numerous studies of Dagestan honeybees showed, that the longest proboscis inherent in bees of mountain zone (6.85 ± 0.03 mm). The plain bees have a smaller proboscis (up to 6.71 ± 0.01 mm), and in the foothills bees the proboscis occupies an intermediate position (from 6.69 ± 0.01 to 6.83 ± 0.01 mm). Two other peculiarities (wing length and the third tergite) are subject to variation, depending on the altitude above sea level.

Event tourism is a relatively young destination in tourism in Abkhazia. The Republic of Abkhazia has huge tourism potential, including for the development of event tourism: natural, cultural, historical and socio-economic resources. Located in a relatively small area, protected from cold winds by the Main Caucasian Range and its spurs, Abkhazia has an excellent climate of humid subtropics. The most important components of the tourism potential are the geographical location, favorable climatic conditions, the presence of endemic flora and fauna, the contrast of the territory, karst relief forms, the presence of balneological resources, and a great cultural and historical heritage. Abkhazia is an ancient Christian country. There are many temples and churches of great cultural and historical importance. With such a rich tourist potential, Abkhazia is in demand for tourists mainly in summer. While in other seasons of the year many objects and phenomena are no less attractive, and some only take place in winter, spring or autumn. This includes winter holidays in the high mountains of Abkhazia with an abundance of snow, and flowering of various plants, and ripening of subtropical fruits, various sports events, national holidays “Lykhnasta”, “Mokashta”, and of course Christian holidays that take place all year round.

In this experiment, colonies of six regional populations from the territory of the Republic of Serbia were included, and two generations (maternal colonies and their offspring) were observed. In two inspections (fall and spring), production traits and temperament were observed. Daughter queen bees mated in uncontrolled conditions (free-mating) in order to determine heritability of production traits in terms of practical beekeeping. The heritability coefficients (h2) for production traits calculated. It was found that the honey yield was mostly determined by genetic, but environmental conditions also had significant influence. Heritability for honey yield (h2) ranged from 72.72% (Rasina population) to 81.04% (Banat population). Colony strength was very dependent on external factors, but also from the very population. When it comes to food supply (honey and pollen), in the inspections, large differences in the heritability coefficient were determined, which is explained by the interaction of genetic factors (the foraging instinct) and environmental factors (honey flora and climatic conditions during foraging) and the influence of beekeepers (feeding, etc.).

Сбор переваримого протеина в первом укосе составил 74% от общего сбора. Обеспеченность 1 корм. ед. зелёной массы галеги восточной переваримым протеином в среднем за вегетационный период составила 159 г, что превысило зоотехническую норму на 39–54 г. В первом укосе она составила 169 г, что выше, чем во втором укосе (146 г) на 16% и в третьем укосе (149) – на 13%. Data on yield and quality composition of the Eastern galega green mass are presented. It has been established that the crop is high-yielding and in the soil-climatic conditions of the northern region of the Republic of Belarus provides three complete cuttings having formed a yield of 484 c/ha of green mass. The maximum yield of green mass (230 c/ha) was obtained in the first growth which amounted to 47.5% of the total yield. In the aftergrass the Eastern galega in terms of yield gave way to the first growth by 34.8% and formed 150 c/ha (31% of the total yield). The third hay crop provided 104 c/ha of green mass or 21.5% of the total yield. Just in three cuttings the Eastern galega provided the total harvest of fodder units from 1 hectare of sowing 98.1 c/ha: in the first growth - 50.6 c/ha, in the second – 28.8 c/ha and in the third cutting – 18.7 c/ha. The third cutting yielded to the second by 54.0%, to the first – 2.7 times. The total harvest of digestible protein from 1 hectare of the green mass of the Eastern galega was 15.6 c/ha: in the first growth – 8.6 c/ha, in the second - 4.2 c/ha and in the third – 2.8 c/ha. The digestible protein harvest in the first growth was 74% of the total harvest. Availability of 1 fodder unit of green mass of the Eastern galega by digestible protein averaged 159 g over the growing season which exceeded the zootechnic norm by 39–54 g. In the first growth it amounted to 169 g which is 16% higher than in the second aftergrass (146 g) and in the third cutting (149) – by 13%.

A growth in the number of deer and an increase in their productivity are closely related to the solution of the complex problem of reproduction and rational use of deer females. Significant damage to reindeer husbandry is caused by the barrenness of northern domestic deer, the level of which has been quite high in recent years. So, in the Republic of Sakha, on 01.01.2020, the number of domesticated reindeer was 152,068, of which female deer and heifers — 71,818, offspring per 100 females — 59, business yield amounted to 52 fawns per 100 females. The causes of infertility are very diverse, as the natural and climatic conditions of the breeding zones have a significant influence on the reproductive function of reindeer. In Yakutia, the main population of northern domestic deer is bred in mountain taiga and tundra natural-climatic zones, so there are about 55 thousand deer in the mountain taiga zone and more than 65 thousand deer in the tundra zone. In this regard, the study of the peculiarities of the postpartum period course in domestic reindeer females, its morphophysiology, and behavioral reactions depending on the natural and climatic conditions of breeding is of great importance.

The article notes that the growing popularity of healthy lifestyles contributes to the increase in consumption of fruits and berries. At the same time, the analysis of the dynamics of the gardening industry for 2000-2018 shows that the problem of providing fresh fruits and berries to the population remains one of the most important. Based on actual data, linear and logarithmic models of time series of key industry indicators for the period 2010 – 2019 have been compiled. Calculations showed that in the Russian Federation as a whole the trend of reduction of sown areas of perennial fruit plantations will continue with growth of yield and gross fees. In this regard, the issues of distribution and introduction of gardens of intensive type are updated. An overview of the views of domestic scientists-gardeners on the concept of “intensive garden” is given. It has been established that the distribution of intensive gardens is possible only if there are favorable natural and climatic conditions and a developed scientific and production base of nursery management. The current state and problems of gardening in one of the leading regions – the Republic of Dagestan - are considered. A significant technological lag of region in the further development of intensive horticulture has been identified. Various directions of intensification process in horticulture as the main and necessary condition of growth of efficient and sustainable production are summarized.

The Republic of Croatia has a long tradition of fruit growing due to its geographical location, climatic conditions, and high quality of fruit crops, especially apple fruits. Apples can be used for the formulation of functional foods either in processed form (e.g., juice), or as a by-product (e.g., apple pomace). However, there is a growing demand for functional foods derived from ancient and traditional plant sources as they are recognized as a very valuable source of health-promoting bioactive ingredients. Similarly, old apple cultivars (Malus domestica Borkh.) are characterized by good morphological and pomological properties, less need for chemicals during cultivation and the higher share of biologically active compounds (BACs) with better sensory acceptability compared to commercial cultivars. However, their nutritional and biological potential is underestimated, as is their ability to be processed into functional food. The importance in preserving old apple cultivars can also be seen in their significance for improving the nutritional composition of other apple cultivars through innovative cultivation strategies, and therefore old local apple cultivars could be of great importance in future breeding programs.

This paper presents a computational tool for estimating energy generated by low-power photovoltaic systems based on the specific conditions of the study region since the characteristic energy equation can be obtained considering the main climatological factors affecting these systems in terms of the symmetry or skewness of the random distribution of the generated energy. Furthermore, this paper is aimed at determining any correlation that exists between meteorological variables with respect to the energy generated by 5-kW solar systems in the specific climatic conditions of the Republic of Cuba. The paper also presents the results of the influence of each climate factor on the distribution symmetry of the generated energy of the solar system. Studying symmetry in statistical models is important because they allow us to establish the degree of symmetry (or skewness), which is the probability distribution of a random variable, without having to make a graphical representation of it. Statistical skewness reports the degree to which observations are distributed evenly and proportionally above and below the center (highest) point of the distribution. In the case when the mentioned distribution is balanced, it is called symmetric.
