This study presents the first detailed dendrochronological research of old trees in Olexandria park, a historical landscape garden established by the Branicki family in the late 18th century in Ukraine. By analyzing tree-ring data from the oldest trees in the park, we aimed to refine our understanding of its developmental stages and verify long-hel...

A major challenge for forestry and nature conservation is the adaptation of forests to climate change, as there are many different climate projections, uncertain about which one will prove accurate. We aimed to estimate current and future changes in the potential ranges of common and cultivated native and exotic tree species in Europe. We also aime...

Коротко представлено мову програмування R (R Core Team, 2020) як сучасний багатофункційний інструмент для науковців. Наведено приклади використання в лісівничих дослідженнях та підкреслено необхідність популяризації використання цього інструменту в Україні.

Two European pine species, Pinus sylvestris and Pinus nigra, are experiencing dieback as a result of the increasing frequency and intensity of extreme climatic events. Recent species distribution models predicted shrinkage of ecological niches in the near future and shifted their habitat range towards the northeast. Consequently, P. sylvestris may...

Alien tree species are considered both a threat to nature conservation and a base for forest management. We compiled species occurrences from biodiversity databases, forest inventories, and literature data. We modeled the availability of potential niches using the MaxEnt method and bioclimatic variables for current conditions, 2041–2060, and 2061–2...

The Chornobyl accident on 26 April 1986, caused tree death near the nuclear power plant and affected forest ecosystems throughout the Chornobyl exclusion zone. Thirty years after the accident, the radiation continues to exert its disastrous effects on the surviving trees. However, the extent to which continuous exposure to radiation over several de...

The extensive radioactive fallout resulting from the 1986 Chornobyl accident caused tree death near the nuclear power plant and perturbed trees communities throughout the whole Chornobyl exclusion zone. Thirty years into the post-accident period, the radiation continues to exert its fatal effects on the surviving trees. However, to what extent the...

The introduction of tree species raises the question of whether they find suitable conditions in their secondary range and whether they can successfully adapt to the new conditions in the context of an unstable climate. Stem secondary growth of trees and the changes in xylem cell structure make it possible to trace the adaptation process to the new...

Wild service tree (Sorbus torminalis) is a rare, endangered, relict species, that is protected by law in many European countries. Outside the species distribution range, the trees are usually planted in botan­ical gardens, parks, arboretums, and at the roadside. Such old introduced trees are an important source of knowledge about species’ acclimati...

Climate change is altering forest ecosystems worldwide, particularly in steppe landscapes, where the rare tree communities are challenged with steadily increasing droughts. In the steppe of Eastern Europe, amid dry conditions, Quercus robur occupies mostly riverine habitats and ravines. Here we study the climate sensitivity and drought vulnerabilit...

As a consequence of native tree species decline and distribution range contraction in Europe, acclimation of the non-native tree species at the edge of their distribution is gaining importance. Although non-native tree species may provide sustainable ecosystem services, as a potentially invasive species they may be a threat to local ecosystems as w...

This paper presents an approach for indirect measuring of 90Sr activity concentration in stem wood of Scots pine`s live trees within the Chernobyl exclusion zone based on values of beta-particles surface flux density from stem bark at a thee height of 1.3 m above the forest floor that obtained by use STORA-TU RKS-01 radiometer-dosimeter under field...

Robinia pseudoacacia is one of the most frequent non‐native species in Europe. It is a fast‐growing tree of high economic and cultural importance. On the other hand, it is an invasive species, causing changes in soil chemistry and light regime, and consequently altering the plant communities. Previously published models developed for the potential...

The green belt of Kyiv includes several rare forest biotopes ringing the city and experiencing numerous disturbances and stressors derived from both urbanization processes and climate changes. The arboreal species perform multiple ecological function and influence overall forested ecosystems vulnerability to natural or anthropogenic factors. We hav...

Pedunculate oak (Quercus robur), a popular species in dendrochronological researches, is known to have two phenological forms. The beginning of buds burst, leaves maturation, and flowering differs by a few weeks between the early form and the late form. This phenomenon is predominantly observed in the south-eastern part of the species’ natural rang...

The radial growth of pedunculate oak (Quercus robur), a species often ecologically dominating European deciduous forests, is closely tied up with local environmental variables. The oak tree-ring series usually contain a climatic and hydrologic signal that allows assessing the main drivers of tree growth in various ecosystems. Understanding the clim...

Floodplain forests are highly productive terrestrial ecosystems that perform crucial ecological functions, e.g. carbon sequestration. Quercus robur, a long-lived hardwood species often dominating in floodplains, is an appropriate object to investigate the long-term aboveground carbon fixation. In this study we apply dendrochronological approaches f...

Large old trees are significant elements of forests, arboretums, botanical gardens and parks and perform a number of unique functions contributing to ecosystem integrity and biodiversity. At the same time human activities such as compaction of topsoil layers, deterioration of soil permeability and soil aeration drive the decline of large old trees....

Climate change has a significant impact on natural ecosystems, particularly on floodplain forests that are among the most transformed ecosystems in the world. The climate sensitivity of dominant species is likely to play a key role in determining the susceptibility of flooded forests to climate changes. Here, we use dendrochronological approaches a...

Сarbon sequestration in young pedunculate oak (Quercus robur L.) trees stems growing in a Feofania Park stand were reconstructed in this article. We used standard dendrochronological approaches to obtain tree-ring and basal area chronologies (1932–2015). The mean radial growth rate of studied trees at age 65 was 3.18±1.06 mm per year and ranged fro...

This poster was presented in the Eurodendro 2017 conference (6-10 September, Tartu, Estonia). It represents the results obtained concerning the response of pedunculate oak (Quercus robur L.) trees growing in a floodplain of the Dnipro River basin near Kyiv to several climatic variables.

Pedunculate oak (Quercus robur L.) is a long-lived species that dominates the extra–zonal natural forests in the steppe landscape of southeastern Ukraine. Although Q. robur is considered to be one of the most important species in European dendrochronology, it has received little attention in the steppe zone because of its scarcity in the often-degr...

On the territory of Feofania Park in Kyiv which is the government designated park the genetic collection of the genus Lysimachia L. has been begun to create. The following aim of this collection is integrated assessment of the pharmacological value of floral oils of the widespread species of this genus in Ukraine. Such species as Lysimachia nummula...

Within the last 220 years the dynamics of carbon storage in stem biomass from age-old pedunculate oaks have been assessed using the tree-ring chronology. The study site was an urban forest Theofania Park in Kyiv. In this research we revealed the trend to increase in annual oak stem biomass with the age and respectively increase in the carbon fixati...
