As a result of the field study, carried out in June 2019, 34 species of bright-spored myxomycetes from 11 genera, 5 families and 4 orders of the subclass Lucisporomycetidae were collected in the Pyatykhatskyi Forest Massif, PFM (Kharkiv, Ukraine). Among the found orders of the myxomycetes, Trichiales (20 species) prevails by number of species, demonstrating much larger diversity, than Cribrariales (7 species), Reticulariales (5) and Liceales (2). Among the families of the Lucisporomycetidae, the leading position is occupied by Trichiaceae (19 species); the rest of the families revealed the fewer number of species. Among the genera of myxomycetes, Cribraria Pers., Trichia Haller, and Arcyria F.H. Wigg. were the most abundant regarding the number of species. The species from the five leading genera represent 70.6% of the total species diversity of Lucisporomycetidae in PFM. All the myxomycetes species were found on substrates formed by tree plant species; only Arcyria cinderea, Hemitrichia serpula and Tubifera ferruginosa were also found on bryophyte, while A. denudata was also collected on the wet soil. Among the substrates formed by woody plants, the two-thirds of myxomycete species were observed on the dead wood. On the substrates formed by Quercus robur, Acer platanoides and Tilia cordata, 18 species of myxomycetes were found, including 14, 12, and 4 species on each of these substrate-forming plants, respectively. The taxonomic structure of the myxomycete biota on different types of substrate-forming plants is significantly different. On Tilia cordata, Fraxinus excelsior and Quercus robur more than half of the taxonomic spectrum is formed by species of Trichiaceae, on the Pinus sylvestris the family Cribrariaceae dominates, while on A. platanoides species from the Reticularaceae appear to be the most diverse. The presence of the only representative of Dianemataceae, C. metallica, found on the bark of T. cordata, and a moderate diversity of Liceaceae on F. excelsior seem to be noteworthy. The data obtained allow us to characterize the biota of the brightspored myxomycetes of the PFM as mostly xylophilic, with a predominance of Cribrariales and Trichiales and a tendency of sporulation on the dominant species of forest-forming plants.

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.

Висвітлено результати досліджень складу насаджень дендрологічних парків Лісостепу України. Встановлено, що в складі насаджень парків кількісно переважають рослини аборигенних видів. Разом із дубом звичайним (Quercus robur L.) паркоутворювальну роль відіграють його супутники: клен гостролистий (Acer platanoides L.), ясен звичайний (Fraxinus exelsior L.), липа серцелиста (Tilia cordata Mill.), клен польовий (Acer campestre L.), клен явір (Acer pseudoplatanus L.), граб звичайний (Carpinus betulus L.), в'язові. Зроблено порівняльний аналіз аборигенної та інтродукованої дендрофлори в дендропарках Лісостепу України з таких критеріїв: функціональність, економічність та естетичність. З погляду функціональності доведено, що садово-паркові об'єкти, основу яких складають аборигенні види покритонасінних, легко створювати, за ними легко доглядати і такі об'єкти є більш довговічними. Доведено, що з економічного погляду парки, створені з покритонасінних аборигенної дендрофлори, є дешевшими за парки, створені з інтродуцентів у 10–15 разів. Встановлено, що парки, створені аборигенною дендрофлорою покритонасінних, мають найбільший позитивний психоемоційний вплив на відвідувачів і є комфортними для відпочинку. Отже, для створення парків, аборигенна дендрофлора є саме тим елементом ландшафту, який повною мірою відповідає основним трьом критеріям оцінки садово-паркового об'єкта, а значить є головним паркоутворювальним елементом.

The article presents a taxonomic analysis for the decorative plants collection in the Polar Experimental Station of the VIR branch. The collection fund of floral and ornamental plants of the VIR Polar Experimental Station currently contains 208 species, 90 cultural forms and varieties from 53 families. The collection of annual crops is represented by 21 genera, 22 species, 69 varieties from 14 families. Perennial herbaceous decorative plants on the Polar OS VIR have 101 genera, 140 species from 40 families. The collection of decorative shrubs at the Polar Experimental Station consists of 20 genera, 47 species from 11 families. From the collection of herbaceous floral and decorative crops, the plants from the Asteraceae family are most represented. The Asteraceae occupies a dominant position in the collection of annuals in terms of the number of species and varieties (8 genera, 9 species, 24 varieties). The families Solanaceae and Violaceae each have one species, but the number of cultivars cultivated at the station (9 and 18, respectively) makes it possible to distinguish them from the general composition of the collection of annuals. Among the decorative herbaceous perennials, the largest number of species (≥10) are the families: aster (18 genera, 24 species), buttercup (7 genera, 12 species), carnation (5 genera, 10 species), rosaceae (7 genera, 10 species). The family Rosaceae in the collection of decorative shrub plants is predominant in number and has 10 genera and 29 species. All decorative plants of the VIR Polar Experimental Station nursery of different life forms are introduced. The main work is aimed at attracting modern varieties, new species, and intraspecific forms to the collection. The analysis of the taxonomic structure of plant species, varieties and forms allows us to identify and recommend the most resistant to extreme growing conditions plants that have high decorative qualities, taking into account modern trends in urban floristics.


The history of the forest of Bialowieza is briefly reviewed. The National Park was created in 1923 in the central and apparently least exploited part of the forest. The composition of the forest varies in relation to the nature of the soils. Almost half of the wooded area of the park is occupied by forest composed of Carpinus betulus, Tilia cordata, Quercus robur, Acer platanoides, Ulmus glabra and Picea abies (Querceto-Carpinetum). The structure of this association is illustrated by maps and transects of selected plots. An almost continuous canopy is formed by Carpinus betulus with tall emergent trees of Tilia cordata, Quercus robur and Picea abies. Tilia cordata regenerates freely and there are numerous groups of seedlings, saplings and young trees which are sometimes in gaps but often beneath the main canopy. The origin of the groups is analysed and evidence is presented that those of T. cordata are probably always less than 50 years old. This is in contrast to analyses made by Paczoski (1928a, b, 1930) shortly after the park was established, when trees of T. cordata with trunk diameters less than 0.3-0.4 m were absent. There is now a discontinuity in the distribution of diameter classes in the population. The influence of this change on the structure of the forest is discussed.

Tree growth is sensitive to soil pH in urban areas and is often higher than in rural forest. However, there are knowledge gaps on how soil pH and alkalization are affected by urban environments and seasonal climate as well as the cascading effects on tree species. In order to fulfill these gaps, we analyzed the soil pHCaCl of four common native deciduous tree species: Acer platanoides, Tilia cordata, Quercus robur and Betula pendula in five different types of urban green spaces in Kaunas city municipality (Lithuania). The results show that soil pH in urban environments with Betula pendula sites were most alkaline (pH 7.04), whereas the soil pH of urban environments with Acer platanoides (pH 6.7) and Tilia cordata (pH 6.8) were most acidic. The soil pH of street tree greeneries was alkaline, while soils of peri-urban forests and large urban parks were acidic. Differently to natural conditions in peri urban forests the soil pH level drop down by 0.5 is observed during spring-autumn period in broad street greeneries with largest urban pressure. The variation in soil pH of the different types of green space and tree species shows that city planner should consider the unique conditions of all green space to maximize their potential for human well-being.

Одной из основных задач лесоводов Самарской области является сохранение и воспроизводство насаждений дуба черешчатого (Quercus robur). Изучены особенности формирования древостоев дуба черешчатого семенного и порослевого происхождений в разных лесорастительных условиях. Объектами исследований являлись естественные насаждения дуба, произрастающие на богатых почвах с сухим, свежим и влажным режимом увлажнения (лесорастительные условия Д1 – Д3). Выявлено, что дуб черешчатый произрастает совместно с березой повислой (Betula pendula), кленом остролистным (Acer platanoides), осиной обыкновенной (Populus tremula) и липой мелколистной (Tilia cordata). Бонитет насаждений дуба порослевого происхождения равен III – IV классу. При этом наиболее высокорослые древостои (19,1 м) с максимальным запасом дубовой древесины (130 м3/га) формируются в дубравах с лесорастительными условиями Д2. В дубравах семенного происхождения наиболее высокие деревья дуба (30,6 м) с классом бонитета Ia формируются в составе насаждений 5Д3Ос2Кл+ЛП, находящихся в лесорастительных условиях Д3. Максимальный запас сыростоячей древесины (230 м3/га) имеют древостои в составе 7Д3Ос+Б, произрастающие в свежих местах обитания с режимом увлажнения, близким к оптимальному — Д2. Дубравы семенного происхождения при практически равном возрасте с порослевыми дубравами по запасу сыростоячей древесины на 1 га в среднем на 56,5 % продуктивнее их. Высота деревьев в семенных дубравах в среднем на 9,3 м, а их диаметр на 12,8 см больше, чем в порослевых дубравах. При этом их бонитет соответствует Ia – I классу.

Investigations of the species diversity of epiphytic bryophytes of the State Dendrological Park “Olexandria” (the historical part and the “Budynok Lisnyka” plot) were conducted in 2017–2019 and revealed 40 species representing 22 genera, 17 families, seven orders, two classes, and two divisions. This corresponds to 46.51 % of the total number of detected bryophytes in the park. The leading families in the bryoflora of the park are Orthotrichaceae (9 species), Brachytheciaceae (6), Amblystegiaceae (3), Anomodontaceae (3), Dicranaceae (3), Hypnaceae (3), and Pottiaceae (2). The leading genera are Orthotrichum (9 species), Anomodon (3), and Dicranum (3).Among the identified taxa, five species (Dicranum tauricum, Orthotrichum lyellii, Porella platyphylla, Sciuro-hypnum reflexum, and Syntrichia virescens) are regionally rare within the Forest-Steppe zone of Ukraine. Most of the recorded epiphytic mosses were found on the bark of Acer platanoides (28 species), Fraxinus excelsior (27), Quercus robur (26), Acer campestre (23), and Tilia cordata (22). The least epiphytic mosses were found on the bark of conifers (Pinus sylvestris, P. strobus, Picea abies, Larix decidua, etc.).The surveyed trees in the State Dendrological Park “Olexandria” were also found such epigeal mosses as Plagiomnium cuspidatum, Ceratodon purpureus, Dicranella heteromalla, and Pohlia nutans, as well as epixilic moss Dicranum flagellare, etc.The “Budynok Lisnyka” plot hosts three species that do not occur in the park’s historical part. In particular, Lophocolea heterophylla and Sciuro-hypnum curtum were found there on Quercus robur trunks and Sciuro-hypnum reflexum on Quercus rubra bark. At the same time, the historical part of the park is characterized by the number of expansive bryophytes.

Abstract The role of the robin as a determinant of heterotrophic consortia is considered. The robin is a consort of determinants of autotrophic consortia, which core is represented mostly by dominating species of deciduous trees (Quercus robur Linnaeus, 1753, Tilia cordata Miller, 1768, Acer platanoides Linnaeus, 1753, Acer campestre Linnaeus, 1753), and also by sedges (Carex sp.) and grasses (Poaceae), connected with the determinants by fabric links. The robin also belongs to the concentr of the second and higher orders as a component of forest biogeocenoses and it is also the main determinant in species composition of the insects inhabiting bird nests. As a result of the taxonomic analysis of invertebrates in the robin nests, it has been found out that the most numerous class was Insecta (9 orders and 27 families), with the dominance of Coleoptera (30.7 %). The nidicolous fauna of the robin (38 species) was dominated by zoophages along with parasites and hematophages such as Hippoboscidae (46.4 %). The percentage of phytophages and saprophages among the invertebrate nest inhabitants was somewhat less (21 % each), then followed necrophages (12 %). Zoophages and parasites also dominated according to the number of objects in the nests (42 %; n = 150), the less was the portion of phytophages (34 %), saprophages (18 %), and necrophages (6 %). The highest number of species and objects of zoophages was recorded for climax and mature biocenoses (oak forests in NNP “HL” and pine cenoses in NNP “H””).

Abstract The aim of the study was to analyze the species composition of the dendroflora near four main roads in the city of Białystok, taking into regard their geographical and historical origin. The wildlife inventory was conducted in the vegetation season of 2011. The inventory revealed presence of a total of 837 trees and bushes representing 36 species and 18 families. The most abundant trees were those from the family Aceraceae (63.8%), while the most abundant bushes were those representing Rosaceae (48.9%). The contribution of native species (65.7%) was found to be about twice as high as that of alien ones (34.3%). The dominant species among the native trees was Acer platanoides L., while the principal bush species was Crataegus monogyna Jacq. The alien tree species were most commonly represented by Acer negundo L., and bushes - by Ligustrum vulgare L. Spontaneously settled trees and bushes were clearly dominant (59.9%) over those originating from plantations (40.1%). Among the native species of local origin, the prevailing species were synanthropic spontaneophytes (52%), including Acer platanoides and Tilia cordata Mill. Anthropophytes were more abundantly represented by diaphytes (22.7%), followed by kenophytes (10.4%). The most abundant species among diaphytes was Ligustrum vulgare, and among kenophytes - Acer negundo.
