Over the last couple of decades, many peer-reviewed publications focused on the bioeconomy, which it is frequently argued to be a key part of the solution to global challenges (climate change, ecosystem degradation). This study investigates the scientific literature on forest bioeconomy by applying a social network analysis to the bibliometric science. The bibliometric network analysis was performed over the time-frame of 2003-2020 to provide an overview on the main aspects characterising the forest bioeconomy issue. The results show that 225 documents on forest bioeconomy were published by 567 organisations from 44 countries. Finland and Canada are...

In order to understand the impact of summer drought on dry deposition of tropospheric ozone (O3), we compared severe and mild drought periods of summer 2018 in a mountain Norway spruce forest at Bílý Kříž, Beskydy Mts. An eddy covariance technique was applied to measure diurnal courses of the ecosystem O3 and CO2 fluxes. Low O3 deposition was recorded in the morning and evening, while the highest CO2 and O3 fluxes were recorded during the central hours of the day. Total O3 deposition during severe drought (soil humidity 13%) was significantly higher than the deposition...

The aim of the study was to compare the response of the radial increment of European ash (Fraxinus excelsior L.) in the Western and Eastern forest steppe of Ukraine to climate change. The growth-climate relationships were estimated for 1961-1987 and 1988-2014 in Western and Eastern parts of the forest steppe. The results indicate that the sensitivity of the ash radial increment in stands of the Western and Eastern forest steppe to climate variations in the second period (1988-2014) was increased compared to the first period (1961-1987). In the second period correlation analysis and response function showed a negative effect of summer droughts...

The aim of this paper is to present the intraspecific differentiation of the curly silver fir (Abies alba Mill.) by the wood structure growing in the Ukrainian Carpathians. To find the morphological distinctions by using the silvicultural and biometric methods, 50 silver fir trees with anomalous wavy-relief stemwood formations were investigated. The trees aged from 94 to 132 years were characterised by the diameter at breast height of 32-59 cm. The length of the wave-grained stemwood varied from 6 to 11.5 m. The amplitude of the wood fibre waves varied from 4.4 to 24.1 mm. The smallest values of the amplitude of the wave-grained wood corresponded...
