The paper aims to study the distribution and communities of two giant hogweed species Heracleum mantegazzianum and H. sosnowskyi in Ukraine. This research was motivated by strong invasive trends, risks for native vegetation and a lack of data on giant hogweeds in Ukraine. We presented phytosociological tables of giant hogweeds communities, maps of their modern distribution in Ukraine, a dendrogram of similarity of the communities, phytoindicative evaluation, and proportions of diagnostic species in the syntaxa. According to our survey and literature data, there are 102 locations of H. mantegazzianum and 405 locations of H. sosnowskyi throughout most of Ukraine, except for the steppe zone, where the limiting factor is the arid climate. The amplitudes of both studied Heracleum species have a significant overlap in the factors of humidity, nitrogen, and salt regime. There are differences between the species in the factors of light, temperature and continentality. The amplitudes of the studied species are the widest for moisture and the narrowest range for soil acidity. Both species favour soils enriched in nitrogen. Based on the phytosociological survey, the species forms two distinct associations Urtico dioicae-Heracleetum sosnowskyi and Urtico dioicae-Heracleetum mantegazzianii and also occurs with lower abundance in communities belonging to 8 vegetation classes. The obtained data can be used to carry out preventive measures against the further spread of giant hogweeds in new habitats with varying degrees of anthropogenic transformation.

Selected forestry parameters were investigated in the system of trees and wood-destroying fungi in the natural forests of the Kyiv city on a gradient of recreational transformation. We investigated the vitality, age compositions, and health condition of woody plants (11 species), and species, systematic, trophic and spatial compositions of xylotrophic fungi (51 species, 224 findings of xylotrophs representing 34 genera, 20 families, 7 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that communities of woody vegetation and xylotrophic fungi in forests depend on the degree of recreational transformation of the environment. Vitality, age compositions and health condition of trees altered species composition of xylotrophs.

“…This reaction manifests itself in a coordinated adaptation between hydrothermal stress and lighting, that is, optimization of the processes of life and productivity [7]. In relation to the impact of a particular factor, each species has its own ecological valence and its own ecological spectrum, which was formed in the course of evolution [8]. Understanding these characteristics gives you the ability to simulate plant response to different climatic conditions.…”

Influence of abiotic factors on CO₂-gas exchange of Pinus pallasiana, Juniperus excelsa and Arbutus andrachne

The complex interactions among environmental factors as incident light, temperature and soil water content create the need for used physiology-based models which describe plants performance under current and changing climatic conditions. In the present work the net photosynthetic rate of Pinus pallasiana D. Don, Juniperus excelsa M.Bieb. and Arbutus andrachne L. was modeled as a function of light irradiance using the modified rectangular hyperbola model, which is capable of describing the photoinhibition by the non-rectangular hyperbola function. A comparative assessment of the adaptive response of the photosynthetic apparatus plants on the effect of abiotic factors and their strategies in maintaining an optimal water balance in accordance with environmental conditions has been performed. The parameters of light curves of photosynthesis under conditions of full sunlight, moderate shading and drought are determined. In relation to light, Pinus pallasiana is characterized by wider ecological amplitude compared to Juniperus excelsa and Arbutus andrachne. Inefficient use of low-intensity of photosynthetically active radiation by immature plants Pinus pallasiana and Juniperus excelsa indicates poor shade tolerance and inability to resume in shade-type forests. Due to the low plasticity to changes in the light regime, Arbutus andrachne L. may experience a significant lack of light in strong shading. Arbutus andrachne has the highest ability to actively rearrange water regime in accordance with its external moisture supply, which causes the highest drought resistance, and Juniperus excelsa has a slightly lower capacity. Tolerance to hydrothermal stress in Pinus pallasiana is significantly lower than in Arbutus andrachne and Juniperus excelsa.
