Subject of research in this article is the urban dendroflora of the Macedonia Park, situated on about 50,000 m2 in the Macedonian capital city of Skopje, i.e., identification and presence of the recent woody plants. Thus, observed are morphological and ecological features of the woody plants and their current state in this urban environment. The investigation relates to a seven-year period (since the establishment of the Park in 2012 up to late 2019). After the field research and the inventorisation of the woody plants in the Park, 82 taxa were identified, represented in 1,318 individuals. Most represented tree species is the hybrid Platanus × hispanica Mill. ex Münchh. with 103 individuals (7.81% of the overall urban dendroflora). Most frequent tree including infraspecific taxa is Fraxinus excelsior L. (including F. e. ‘Globosa’, F. e. ‘Jaspidea’, and F. e. ‘Pendula’) with a total number of 146 individuals (11.08%). Concerning other growth form, the mini and small tree roses of hybrid Rosa Floribunda Group outnumber all ornamental woody species with 225 bushes (17.07%). Climbers are represented with 3 taxa (3.66% of identified taxa) in pergolas (Wisteria sinensis /Sims/ Sweet, Parthenocissus quinquefolia /L./ Planch.), and wire cage topiary (Hedera helix L.). Likewise, 87 individuals (6.60%) of 10 species (12.19%) occur as remnants of the greening in the past of which 3 species are used as a green core of a small sacral architecture: Cupressus sempervirens var. horizontalis (Mill.) Loudon (with 10 trees), Platycladus orientalis (L.) Franco (3), and Pinus nigra J.F.Arnold (1). In general, the urban dendroflora is properly selected and used for greening, although certain species and individuals are withering (e.g. Betula pendula ‘Youngii’, Juniperus scopulorum ‘Skyrocket’, F. e. ‘Jaspidea’) or unsuitably used for avenue and in small alpine-like garden.

The materials of the field research of synanthropic vegetation in the territory of the Kobuleti in the 2016–2020 years are provided. In particular, 134 taxa belonging to 49 families and 97 genera were revealed in the three different plant communities (Cryptomerietum japonicae, Eucalyptetum-viminali-globulo-cinerei, and Cinnamomo glanduliferae-Cryptomerietum japonicae) in the Kobuleti lowland. The community Cryptomerietum japonicae comprises 66 taxa, 33 of which are native, and 33 have an alien origin. Woody plants in Cryptomerietum japonicae are represented by 15 taxa. The community Eucalyptetum-viminali-globulo-cinerei comprises 91 taxa, 36 of which are native and 55 are alien. Woody plants in Eucalyptetum-viminali-globulo-cinerei are represented with 17 taxa, while the rest 74 taxa are herbaceous. In Cinnamomo glanduliferae-Cryptomerietum japonicae there are discovered 49 plant taxa, including 25 native and 24 aliens. In this community, 16 taxa are represented by woody plants and 33 taxa – by herbaceous ones.Therefore, in the investigated region, 60 taxa (44.77%) were found to be native and 74 taxa (55.23%) alien. Among aliens, 31 taxa have East Asian origin, 16 taxa are from the Mediterranean, 13 taxa originated from Europe, ten taxa originated from North American, and four – originated from Australia.Despite cuttings and artificial planting of alien representatives, some indigenous woody species (i.e., Corylus avellana, Frangula alnus, Vaccinium arctostaphylos, Smilax excelsa, Quercus hartwissiana, Carpinus caucasica, Castanea sativa, and Hedera colchica) still occur in this territory. Both native and alien taxa participate in the formation of the described landscape structure. Successional events have started in the Kolkheti Lowland in ancient times. It is a long-term process, which is still ongoing, as our observations confirmed it.

Актуальность связана с расширением зеленого строительства на новых территориях в разнообразных и нередко тяжелых природных и агротехнических условиях возникла потребность в широком и разнообразном по биологическим и техническим свойствам ассортименте древесных пород и разработке дифференцированных методов их выращивания. Интродукция должна быть основана на обстоятельном изучении существующего опыта интродукции и знании стран – источников интродукции, истории формирования того или иного вида, учета экологических особенностей местообитаний, вертикальной зональности, существования географических и эдафических форм. Цель исследования заключалась в изучении эколого-биологических особенностей таксонов семейства Cupressaceae Bartl. в дендрологических коллекциях сухостепного региона. Исследованы шесть древесных вида семейства Cupressaceae, произрастающие в дендроколлекциях ФНЦ Агроэкологии РАН: Juniperus virginiana L., J. communis L., J. sabina L., Thuja occidentalis L, Platycladus orientalis(L.) Franco, Pseudotsuga menziesii (Milb) Franco. Изучены естественные ареалы объектов исследования. Выявлено, что виды подсемейства Thujoideae встречаются как в северном, так и в южном полушарии, виды подсемейства Juniperoideae (род Juniperus) – в умеренных областях северного полушария. Фенологические наблюдения выявили, что рост хвои у можжевельника обыкновенного начинался одновременно с ростом побегов в конце марта - начале апреля (на 1-1,5 месяца раньше, чем на родине), Период роста хвои продолжался 2-2,5 месяца, побегов – 135-180 дней. В ходе наблюдений за динамикой роста сеянцев, были получены метрические показатели сеянцев, 1-летние сеянцы Platycladus orientalis – 16-18 см, Thuja occidentalis – 9-14 см, J. communis – 10-15 см, J. sabina – 14-16 см, Juniperus virginiana – 14-16 см высотой. Анализ изменчивости морфологических признаков и биоэкологических свойств, адаптаций в новых условиях среды имеют большое значение для биоэкологического обоснования введения в культуру древесных таксонов семейства Cupressaceae. Этот анализ затрагивает оценку природного разнообразия растений с таких важных сторон, как скорость роста, устойчивость и декоративность, сведений о которых в засушливых условиях крайне мало. The urgency is connected with the expansion of green construction in new territories in diverse and often difficult natural and agrotechnical conditions, there is a need for a wide and diverse assortment of tree species in terms of biological and technical properties and the development of differentiated methods of their cultivation. The introduction should be based on a thorough study of the existing experience of introduction and knowledge of the countries - sources of introduction, the history of the formation of a particular species, taking into account the ecological features of habitats, vertical zonality, the existence of geographical and edaphic forms. The aim of the study was to study the ecological and biological features of the taxa of the Cupressaceae Bartl family. in dendrological collections of the dry-steppe region. Six woody species of the Cupressaceae family growing in the arboretum collections of the Federal Research Center of Agroecology of the Russian Academy of Sciences were studied: Juniperus virginiana L., J. communis L., J. sabina L., Thuja occidentalis L, Platycladus orientalis (L.) Franco, Pseudotsuga menziesii (Milb) Franco. The natural areas of the objects of study have been studied. It was revealed that the species of the subfamily Thujoideae are found in both the northern and southern hemispheres, the species of the subfamily Juniperoideae (genus Juniperus) – in the temperate regions of the northern hemisphere. Phenological observations revealed that the growth of needles in common juniper began simultaneously with the growth of shoots in late March - early April (1-1.5 months earlier than at home), the period of growth of needles lasted 2-2.5 months, shoots - 135-180 days. During observations of the growth dynamics of seedlings, metric indicators of seedlings were obtained, 1-year-old seedlings Platycladus orientalis - 16-18 cm, Thuja occidentalis - 9-14 cm, J. communis - 10-15 cm, J. sabina - 14-16 cm, Juniperus virginiana - 14-16 cm tall. Analysis of the variability of morphological features and bioecological properties, adaptations in new environmental conditions are of great importance for the bioecological justification of the introduction of woody taxa of the Cupressaceae family into culture. This analysis affects the assessment of the natural diversity of plants from such important aspects as growth rate, stability and decorative properties, information about which is extremely scarce in arid conditions.

Nanotechnology is a promising tool that has opened the doors of improvement to the quality of human’s lives through its potential in numerous technological aspects. Green chemistry of nanoscale materials (1–100 nm) is as an effective and sustainable strategy to manufacture homogeneous nanoparticles (NPs) with unique properties, thus making the synthesis of green NPs, especially metal nanoparticles (MNPs), the scientist’s core theme. Researchers have tested different organisms to manufacture MNPs and the results of experiments confirmed that plants tend to be the ideal candidate amongst all entities and are suitable to synthesize a wide variety of MNPs. Natural and cultivated Eucalyptus forests are among woody plants used for landscape beautification and as forest products. The present review has been written to reflect the efficacious role of Eucalyptus in the synthesis of MNPs. To better understand this, the route of extracting MNPs from plants, in general, and Eucalyptus, in particular, are discussed. Furthermore, the crucial factors influencing the process of MNP synthesis from Eucalyptus as well as their characterization and recent applications are highlighted. Information gathered in this review is useful to build a basis for new prospective research ideas on how to exploit this woody species in the production of MNPs. Nevertheless, there is a necessity to feed the scientific field with further investigations on wider applications of Eucalyptus-derived MNPs.

AbstractThe woody plant species composition has been evaluated in three cadastral territories of southwestern Slovakia, together in 77 habitats of non-forest woody vegetation (NFWV). A total of 43 tree species have been identified; 8 of them were alien and 5 species were cultural fruit trees. In total 20 shrub species were identified, out of which 3 were alien. Three woody species are classified as invasive according to the law in Slovakia: Acer negundo L., Ailanthus altissima (Mill.) Swingle, and Lycium barbarum L. They occurred only in 2, maximum in 4 of the evaluated habitats. The most occurring alien tree species Robinia pseudoacacia L. was generally identified in 58 habitats and in 48 habitats, with an incidence over 40% and dominance index of 70.6. The second most occurring alien tree Populus × canadensis had a dominance index of 8.3. The dominant native trees in NFWV were Acer campestre L., Fraxinus excelsior L., Quercus robur L., Salix fragilis L. with the dominance index of 1–5 only.

The threat which is on the forests and wooded spaces of Africa and particularly those of Côte d'Ivoire is accentuated over the years. The quoted leading causes are the land pressure related to demography, the anarchistic exploitation of the forest woody plants and itinerant agriculture. In many cases, the afforestation is the recommended palliative measure. But with which woody plants does one retimber in Côte d'Ivoire? Which assessment are previous initiatives made? On several occasions the exotic woody plants with rapid growth were used without success. The main objective of this study is to identify local woody plants with rapid growths of which the use will contribute to a significant degree to fast regeneration of our forests, degraded spaces and the post-farming fallow. Floristic inventories and measurements were carried out on the stems of Albizia adianthifolia and Albizia zygia in elementary plots of 400 m ² (20m X 20m). Two local arborescent Leguminous plants with rapid growth were identified for this purpose. They were: Albizia adianthifolia and Albizia zygia. The experiments showed that these species reach the maximas of their growth in height and thickness as from nine (9) years. The sowing of the fallow and/or spaces degraded by these woody species supports the fast regeneration of these degraded spaces.

Absorption and translocation patterns of radio-labelled glyphosate (N-(phosphonomethyl)glycine) were examined in four species of woody plants to determine mechanisms of herbicide tolerance in species common to the southeastern United States. Loblolly pine (Pinustaeda L.) and yaupon (Ilexvomitoria (L.) Ait.), both tolerant to the herbicide, absorbed significantly less glyphosate than did red maple (Acerrubrum L.) or white oak (Quercusalba L.), indicating the importance of foliar absorption as a barrier to glyphosate entry. Although herbicide absorption was similar between the sensitive white oak and the tolerant red maple, white oak accumulated more glyphosate in the roots than did red maple, indicating that translocation patterns also contribute significantly to glyphosate tolerance in some woody species.

A rapid method of determining CO2 compensation concentrations was developed and applied to woody plants. Whole leaves, needle fascicles, and twigs were excised, the cut ends inserted in a vial of deionized water, and the assembly placed in a Mylar bag. The bag was filled with air containing ca. 400 p.p.m. CO2. After 1 h in a growth chamber (24 °C, 3800 ft-c (40 660 lux)), the air was expelled from the bag through an infrared gas analyzer. Compensation concentrations determined by this method agreed with values obtained by using conventional closed-circuit gas analysis. The method was successfully applied to 14 gymnosperm and 55 angiosperm woody species and clones, including field-grown plants and rooted cuttings grown under controlled environment. Variation among species was small, compensation concentrations usually falling between 55 and 65 p.p.m. CO2, the range associated with C3 plants. The influence of temperature, moisture stress, and leaf ontogeny on leaf CO2 compensation also was studied.

We studied beavers’ dietary preferences and the role of several factors (such as plant species, size and anthropopression level) that affect the beavers’ foraging in northern Poland. Woody plants along the river were measured and classified according to species in six 100 m-long transects that were characterized by a diversified human disturbance level. Ivlev’s electivity index was used to present the beavers’ preferences for various plant species and sizes, and the generalized linear model was used to assess the significance of studied factors in beavers’ browsing choices. Most popular in the beavers’ diets were willows (Salix), maples (Acer) and alder (Alnus), but only willows and maples were preferred. We noted a decrease in the beavers’ foraging preference in parallel to an increase in the shoot diameter; plants with a diameter below 10 cm were preferred. All factors included in the generalized linear model (GLM) were significant in shaping the beavers’ foraging choices. A negative correlation between the shoot diameter and the human disturbance level was found, but the species composition of the browsed woody plants was the same in each transect. Beavers’ foraging preferences, as observed in our study, were similar to those described in the literature and confirmed the role of woody species and their diameters in shaping the beavers’ diet. We also suggested the potential role of anthropopression in the shaping of the beavers’ foraging behaviors.

Thirteen termite mounds and 13 similar-sized control plots were surveyed in central Zimbabwe in order to study large mammalian browsing and vegetation characteristics. The mounds supported almost twice as many tree species as the control plots and the woody vegetation was denser on mounds compared with the woodland plots. Species of woody plants were recorded along with the percentage of branches browsed (cumulative browsing score) by black rhino, Diceros bicornis, elephant, Loxodonta africana and other browsers combined. In addition we measured how the cumulative browsing score on three woody plant species, Acacia nilotica, Colophospermum mopane and Dichrostachys cinerea, which were common both on and off mounds, was related to the distance from mound centre. Both black rhino and elephant cumulative browsing scores were significantly higher on the mound plants compared with the woodland plots. Cumulative browsing score was negatively related to distance from the mound centre for Dichrostachys cinerea, Colophospermum mopane and Acacia nilotica. We propose that termite mound construction in miombo woodland contributes to sustaining populations of megaherbivores and perhaps some woody species in these areas.

What determines large-scale patterns of species richness remains one of the most controversial issues in ecology. Using the distribution maps of 11 405 woody species in China, we compared the effects of habitat heterogeneity, human activities and different aspects of climate, particularly environmental energy, water–energy dynamics and winter frost, and explored how biogeographic affinities (tropical versus temperate) influence richness–climate relationships. We found that the species richness of trees, shrubs, lianas and all woody plants strongly correlated with each other, and more strongly correlated with the species richness of tropical affinity than with that of temperate affinity. The mean temperature of the coldest quarter was the strongest predictor of species richness, and its explanatory power for species richness was significantly higher for tropical affinity than for temperate affinity. These results suggest that the patterns of woody species richness mainly result from the increasing intensity of frost filtering for tropical species from the equator/lowlands towards the poles/highlands, and hence support the freezing-tolerance hypothesis. A model based on these results was developed, which explained 76–85% of species richness variation in China, and reasonably predicted the species richness of woody plants in North America and the Northern Hemisphere.
