Abstract

The co-adaptive system of tree vegetation and wood-destroying (xylotrophic) fungi in artificial phytocoenoses (in an old-aged, and middle- aged ash-hornbeam oakery and monocultures of Pinus L.) of Forest-Steppe zone of Ukraine was analysed from the point of selected forestry parameters. We investigated the vitality, age, phytosanitary structures of pure acerous (Pinus strobus L., P. sylvestris L.) and mixed broad-leaved stands (Carpinus betulus L., Fraxinus excelsior L., Quercus robur L., Tilia cordata Mill.) and species, systematic, trophic structures of xylotrophic fungi (39 species of macromycetes representing 32 genera, 22 families, 9 orders of 2 divisions: Ascomycota (classes Leotiomycetes and Sordariomycetes) and Basidiomycota (class Agaricomycetes)). The results showed that the species composition and the structure (vitality, phytosanitary) of artificial phytocoenoses altered both the composition of xylotrophs and the levels of the damage of tree stands caused by them.

Abstract

Assessment of relationships and diversity indices between bird’s communities and composition of the forest ecosystem is an important subject of synecological research to identify the intensity of human impact on the flora and fauna. Urban recreation is one of the major causes of violation of the structural and functional integrity of the forest ecosystem. Studies of avian complex and phytocoenosis have focused on the impact of urban recreation on the compositions of tree, shrub and herbaceous layers and species, trophic and ecological compositions of breeding-birds and feeding-birds communities. This paper compares the measurement of the diversity of bird communities and forestry vegetation (diversity indices, dominance indices, distribution uniformity indices) of intensive, medium, moderate and weak stages of recreational transformation of biotope. The stands formed Quercus robur L., Carpinus betulus L., Acer platanoides L., Tilia cordata L. The floristic list comprised 78 grass species. A total number of 43 species of avifauna including 37 breeding species are observed during the study. There were significant correlations between vertical heterogeneity of tree distribution and abundance, species richness and nesting density of birds. The interrelationship between species diversity of birds and floristic richness was also confirmed.

Abstract

Selected forestry parameters were investigated in the system of tree vegetation and wood-destroying fungi in parks of the Kyiv city along a gradient of recreational transformation. We investigated vitality, age structure and health conditions of woody plants (Acer platanoides L., Aesculus hippocastanum L., Carpinus betulus L., Frangula alnus Mill., Pinus sylvestris L., Quercus robur L., Q. rubra L., Sambucus nigra L., Tilia cordata Mill.), and species, systematic, trophic and spatial compositions of xylotrophic fungi (27 species of xylotrophs representing 22 genera, 16 families, 6 orders of divisions Basidiomycota; class Agaricomycetes). The results showed that the communities of tree vegetation and xylotrophic fungi in parks depend on the degree of recreational transformation of the environment. Vitality, age structure and health conditions of trees altered species composition of xylotrophs.

Abstract

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.
