Abstract For the Southern Coast of Crimea, the problem of park communities’ productivity, due to the high recreational load on the environment and climate change, is of particular relevance. The aim of the research was to study the features of the introduced park communities evergreen aboveground phytomass formation and seasonal growth in the conditions of the Southern coast of the Crimea. A comparative assessment of vegetative shoots seasonal growth features of plants Laurus nobilis L., Prunus laurocerasus L., Viburnum tinus L., Aucuba japonica Thunb and Nerium oleander L. was performed. It was found that the time of renewal of shoot growth in spring after winter dormancy in V. tinus and A. japonica began at 459-462 °C, P. laurocerasus - 649 °C, and L. nobilis - 886 °C and N. oleander - 990 °C amounts of active air temperatures above 5 °C. The largest growth (49.3 cm) and the accumulation of leaf phytomass (42.3 cm3) differ in annual shoots of N. oleander. P. laurocerasus has a great potential with a phytomass volume an annual shoot of 24.5 cm3. The increase of shoots phytomass in V. tinus, A. japonica, and L. nobilis is 7-8 times less than that in N. oleander.

In 2018-2020 phenological observations of Cydalima perspectalis Walker were carried out in two agroclimatic regions of the Crimea. The pest, both on the Southern Coast of the Crimea and in the central foothill zone, develops in three generations. The sum of effective temperatures required for the development of generations varies over the years in a wide range, which is due to the asynchronous development of the caterpillars of C. perspectalis . The beginning of summer of the adults of the overwintered generation over the years of research in both regions differed insignificantly and was noted with the accumulation of the sums of effective air temperatures above 10°С on the Southern Coast of the Crimea from 210 to 297 degree days, and in Simferopol - from 222 to 299 degree days. It was found that in the summer months in the central foothill zone of the Crimea, in terms of temperature indicators, more favorable conditions are created for the development of boxwood firewood than on the Southern Coast of the Crimea. The combination of hydrothermal conditions, in which air temperatures exceed 33-36°C, and the relative humidity drops below 19-49%, cause the death of up to 20-28% of Cydalima perspectalis egg embryos at an early stage of embryogenesis. From the embryos of eggs of later stages of embryogenesis, under these conditions, the hatching of caterpillars occurred by 100%.

Different climatic conditions of the greenhouse and open ground determine the growth characteristics of Juniperus excelsa M. Bieb. During the studied vegetation period, three periods of trunk diameter growth were observed in the field vegetation experiment: in March–May, two growth peaks – at the first peak – 1% (0.68 mm), at the second one – 8.83% (3.72 mm). In July-August by 4.74% (1.69 mm), and in SeptemberOctober by 4.9% – (1.53 mm), the increase in the trunk diameter for 2019 was 18.96% or 7.62 mm. In greenhouse conditions, there were two growth peaks: in March-July, the first peak was an increase in d,% by 7.12% (1.11 mm) – while there was a slowdown in growth (April, 28 –May, 27) and (July, 13 – July, 25). The second peak is an increase in d,% by 5.06% and a slowdown in growth (November, 05 – November, 14). Total increase in d,% was 12.18% (1.899 mm). The increase in d,% in the conditions of vegetation experiment is 6.48% more than in the greenhouse conditions. Optimal and limiting values of the studied parameters of the environment and d,% for both research variants are found, and equations of nonlinear dependence between them are constructed. An increase in air temperature to 30-35°C causes a decrease in growth intensity. The research made it possible to determine the optimal and limiting conditions for the growth of this species in the conditions of the Southern Coast of the Crimea and the possibility of its introduction to other regions.

The dependence of the growth rate of Arbutus andrachne L. on some environmental factors was studied under the conditions of the Southern Coast vegetation experiment in different periods of the species vegetation, which made it possible to find the optimal and limiting conditions for its growth. In March, vegetation began at an average daily air temperature of 3.5 – 7.50 °C and the increase in stem diameter was approximately 0.42 % (0.09 mm), at the second stage (April-May) – 3.7 % (0.58 mm) with a further exit to plateau. In July - August, two sections of the d % change are observed: the first section is from July 27 till August 19 - intensive growth of d % by 12.58 % (1.961 mm), the second section after August 19 – access to the growth plateau, which is associated with an increase in air temperature to 30-35 °C. In September-October, two sections of the d % change are observed: the first section lasted from September 01 till September 15 - intensive growth of d % by 3.55 % (0.582 mm), the second section after September 15 – exit to a plateau of growth, lowering the air temperature to 8-10 °C and the end of the growing season. In November, an increase in trunk diameter was not observed. The optimal environmental factors were: in March-May, Ta = 20-2 °C, Da = 0.4-1.2 kPa, I = 300-900 mmol / m2s; July-August, Ta = 22-28 °C, Da = 1.4-2.5 kPa, I = 500-1000 μmol / m2s; in September-October, Ta = 16-25 °C, Da = 0.3-1.5 kPa, I = 400-800 μmol / m2s, respectively. The results of our experiments allow us to compare the ecological and physiological characteristics we obtained with the climatic conditions of a particular region and evaluate the possibilities of introducing it into other regions.

The aim of the work is to supplement and clarify the annotated list of vascular plants of “Castel” nature reserve on the Southern coast of the Crimea. Methods. The work is based on the results of long standing field research, which was carried out by the traditional route-reconnaissance method, analysis of YALT herbarium materials and data from literary and Internet sources. Arealogical and biomorphological characteristics of species are given according to "Biological Flora of the Crimea" by V.N. Golubev, biotope coding according to EUNIS habitat classification. The nomenclature of taxa corresponds to the " Spontaneuos flora of the Crimean peninsula" by A.V. Yena and to international databases Euro+Med PlantBase, The Plant List, Catalog of Life. Results. An additional annotated list of vascular plants of “Castel” nature reserve has been compiled, including 152 species, subspecies and cultivars from 97 genera of 38 families, of which 53 genera and 11 families have also not been cited for this territory before. Arealogical, biomorphological, biotopic and sozological characteristics of the taxa are given. As a result of a critical analysis of the list previously published by E.S. Krainyuk, four species were redefined, two species were proposed to be excluded from the flora of the specially protected natural area, several taxa are considered doubtful. Conclusions. The list of vascular plant taxa in “Castel” nature reserve has been supplemented with 11 families, 53 genera, and 152 species, subspecies, and cultivars; several species from the previously compiled list have been proposed to be excluded or considered doubtful. Thus, the flora of the protected area includes at least 425 species from 68 families. For the first time, the biotopic characteristic of the flora of the reserve was established.

Abstract Isodontia mexicana (Hymenoptera, Sphecidae), a New Invasive Wasp Species in the Fauna of Ukraine Reared from Trap-Nests in the Crimea. Fateryga, A. V., Protsenko, Yu. V., Zhidkov, V. Yu. - Th e North American wasp Isodontia mexicana was found for the first time in Ukraine in trap-nests operated near Pushkino (southern coast of the Crimea) in 2012. Th ree nests contained five cocoons, from which only one adult wasp emerged in 2013, allowing the positive identification; other cocoons were either empty (one) or destroyed by Melittobia acasta (three). Such a find of a newly established invasive species in Ukraine represents the easternmost point in its European range and possibly the most remarkable jump-dispersal event in its distribution.

Abstract. The work was carried out to modify the method of assessing the viability of plants, taking into account the limiting factors of the climatic conditions of the Orenburg Preduralie. Are studied several species of plants, during the introduction at the steppe zone (on example of Оrenburg). Introduction study of all taxons was carried out for 8 years (20122020). The results of visual and laboratory observations of the seasonal development of species. During the entire observation period such indicators, as lignification of shoots, heat resistance, drought resistance, winter hardiness, shoot-forming capacity, height increase, generative development, and possible ways of reproduction in culture were evaluated annually. For each indicator numerical values in points corresponding to a certain state of the plant were selected. Based on the integrated assessment, the total viability score was calculated separately for each year of observations and the average score for the observation period. The sum of the average scores is an integral numerical expression of the viability of the introduced plants. Was established that the studied species belong to the I and II group relatively the criterion of life skills. The most species and sorts are among the most promising plants for introduction.
