Abstract: The present study is focused on European beech (Fagus sylvatica L.) growth in eastern Bohemia in the Broumovské stěny National Nature Reserve, Czech Republic. The objective of this research was to develop an evaluation of European beech radial growth in relation to solar activity (number of sunspots), air temperature in the growing season, annual precipitation and air pollution (SO2 depositions). The highest positive significant correlation coefficient was found between radial growth of European beech and number of sunspots, followed by the correlation with air temperature in the growing season. The radial growth showed a negative significant correlation with SO2 depositions. The correlation of the radial growth indicates that precipitation and sunspots have a lower correlation coefficient with beech growth than seasonal temperature during an air pollution disaster in the 21st solar cycle. Radial growth, precipitation total and air temperature in the growing season were processed by spectral analysis for the evaluation of periodic cycles. The 7.5- to 11-year cycles were observed in air temperature and in sunspot cycles. Precipitation and air temperature in the growing season indicate a higher frequency at 3.7-year cycles. The long-term periodicity of radial growth was influenced by both solar activity and fluctuations of growing-season air temperature.

The marker was reliably used to identify A. ibericum as well as to gain preliminary insights into the genetic diversity of Georgian populations. MegaBLAST searches of studied samples against the GenBank database revealed that all studied accessions could be considered Acer ibericum. Populations from Vashlovani National Park revealed the presence of unique ribotypes, and together with the population from Shavi Mountain, they were identified as the most genetically diverse ones. Based on presented data the populations from Eastern Georgia should be prioritized if conservation measures are planned.

The study intends to offer engineers and farm owners a solution for small-size seed improvement before sowing. The effect of low-intensity coherent light on the seeds of various crops is theoretically and empirically hypothesized. The seedlots of Scots pine (Pinus sylvestris L.) and sugar beet (Beta vulgaris L.) of Russian diploid hybrid RMS-127 were germinated in a controlled environment. The germinants were produced from six seed fractions, previously irradiated with 1.274 W.m-2 at the 632.8 nm wavelength with 1, 2, 3, 5, 10, 15 min exposure to a standard laser system, plus untreated control. Pine germinants were measured on day 15, beetroot on day 10 after germination. An increase in exposure time reduced Scots pine germination energy and capacity, while for sugar beet the results were not conclusive. On the contrary, increasing the exposure time had a positive effect on both the height and biomass growth of both Scots pine and sugar beet germinants. The 10-min exposure time resulted in maximum values for sugar beet height and biomass and Scots pine height, while the 15-min exposure time produced maximum Scots pine biomass.

The woodland key habitat (WKH) is one such initiative that aims to protect biodiversity. This generally involves two key actions: (i) the creation of policy (conservation action) and (ii) the consequences of the policy or initiative in the field. However, the final step of measuring their success in the field is often missing. The aim of this study is to assess the contribution of the WKH initiative to conserve biodiversity in Lithuania. We compared the changes in spatial distribution, species assemblages and richness within the WKH network between 2005 and 2017. Results showed that the spatial distribution of WKHs decreased in number and by area after 12 years. However, species occurrence, abundance and richness of the WHK network generally increased. In conclusion, we found the WKH initiative has contributed to the conservation of forest habitats and biodiversity in Lithuania. However, the future of the WKH network is uncertain due to the current voluntary system, lack of support and funding.
