The activities of superoxide dismutase, catalase and peroxidase in Scots pine populations growing in the contaminated areas of Bryansk region were investigated. The dose rate at the experimental sites ranged from 7 to 130 mGy/year. It has been identified that the activities ofantioxidant enzymes do not depend on the radiation factor under these dose rates. These doses were found to be insufficient for forming significant physiological effects.

Climate change has profound implications for the distribution of suitable habitats for woody species. In this study, we assessed the optimal distribution thresholds for twelve woody species on the Loess Plateau using the Maximum Entropy (MaxEnt) model, incorporating sample points of tree species alongside relevant environmental variables. We analyzed the sustainability of potentially suitable zones and proposed a framework for selecting a regulatory model to establish the most suitable creation zones in response to future climate change.

Plant secondary metabolites (PSMs) may improve gastrointestinal health by exerting immunomodulatory, anti-inflammatory and/or antiparasitic effects. Bark extracts from coniferous tree species have previously been shown to reduce the burden of a range of parasite species in the gastrointestinal tract, with condensed tannins as the potential active compounds. In the present study, the impact of an acetone extract of pine bark () on the resistance, performance and tolerance of genetically diverse mice () was assessed.

Honey is a valuable natural product with antioxidant properties, and its quality is influenced by various factors, including botanical origin and biofortification. Pine bud extracts, known for their antioxidant capacity, were explored to enhance the properties of acacia and polyflower honey. This study aimed to investigate the effect of pine bud extracts at different maturation stages on the moisture content, dry matter, antioxidant activity, and total phenolic content (TPC) of acacia and polyflower honey.

Methyl jasmonate is a plant signaling molecule involved in a wide range of functions, including stress responses. This study investigates the relative differential expression of microRNAs and their target genes in response to methyl jasmonate treatment of Scots pine needles. A combined strategy of high-throughput sequencing and in silico prediction of potential target genes was implemented.

Minor and trace elements in soil play a crucial role in regulating ecological processes that sustain the functionality of forest ecosystems. In this study, we have selected three conifer forests (, , ), one broadleaf forest () and one mixed forest of and in the Winter Olympic core area and determined the pattern of 12 typical elements (B, Fe, V, Cr, Ni, Co, Mn, As, Cu, Zn, Sn and Se) in soils and their main drivers in the three different soil layers (A, B and C horizon) in each soil profile. Our results showed that the concentrations of B, Fe, Cr, Cu, Ni and Sn were mainly enriched in the broadleaf forest and mixed broadleaf-conifer forest zones, and the average concentrations of Co, Mn, V, Zn, As and Se were mainly enriched in coniferous forest zones in contrast.
