Summary: The study found that the right/freedom to harvest trees from farms and transport them to markets was considered the most important factor influencing household perceptions of tree-planting for energy, followed by lack of awareness of tree-planting programs and the availability of free fuelwood from natural forests. Factors such as farm size, education level, distance to forest reserves, and age of the household head were also found to have a significant impact on household perceptions of tree-planting for energy.

Summary: This study found that tree age has a significant impact on various wood properties of black locust, with older trees exhibiting higher values of these attributes. In contrast, the effect of tree diameter was less pronounced, with no significant impact found for certain parameters. Overall, the highest technical quality wood was found in the youngest trees, surpassing native Polish tree species such as oak or beech.

Summary: Veteran tree hollows, which are crucial microhabitats in ecosystems, are influenced by the complexity of the associated food web. A study in Norway found that a complex community structure with macrofauna and mesofauna led to greater biodiversity, increased decomposition rates, and higher wood mould production. This highlights the importance of food web complexity for promoting biodiversity and ecosystem functioning in veteran tree hollows.

Summary: Climate-driven tree mortality threatens temperate boreal forests. Progeny trials found minimal impact of aridity on wood density and microfibril angle. Genetic differences between families did not affect transition out of juvenile wood production.

Summary: This study evaluated the physical and mechanical properties of plantation Japanese larch wood by measuring various indicators with reference to Chinese national standards. The results showed that growth ring characteristics and latewood percentage were related to the wood's physical and mechanical properties. Growth ring width was found to be the most suitable for evaluating MOE and MOR, while latewood percentage was suitable for evaluating air-dry density, radial air-dry shrinkage, IBS and UTS. RW can be used to differentiate juvenile wood and mature wood.

Summary: This study assessed the impact of honey production management on beekeeping welfare and investigated physicochemical honey properties, population development, and immune system gene expression patterns. The results showed that honey production is influenced by hive space and the immune system gene expression of foragers is also affected.

Summary: The Chinese chestnut and other Castanea species have been circulated among growers and scientists in the United States for over a century. More than 100 cultivars have been named in the US, with a subset remaining relevant for commercial production and breeding. The University of Missouri Center for Agroforestry curates a repository of over 60 cultivars, providing open-pollinated seeds to growers since 2008.

Summary: After ten years of release cutting around old retained oaks in a Norway spruce stand, it was found that the treatment did not impact spruce production but promoted oak growth and vitality. Additionally, release cutting led to higher cover and species richness of understory vegetation in the stand.

Summary: Wood juice, a harmful waste from wood processing, was investigated for synthesizing bioplastics. Using Bacillus sp. G8_19, it was found that wood juice from spruce/fir trees resulted in higher PHA content compared to that from Douglas fir trees. This concept could potentially lead to the valorization of wood waste through the production of biodegradable materials.

Summary: Recent investigations have shown that incorporating different natural fibers in the rotational molding process is possible. This study focuses on studying the sintering process of composite materials made of recycled high density polyethylene and wood particles under the influence of rotational molding parameters, identifying the optimal mechanical properties and molding parameters for wood-plastic composite materials.

Summary: The δ18O value of alpha-cellulose extracted from modern and fossil wood is widely used to reconstruct climate. It has been suggested that measuring δ18O directly on whole wood could be more efficient and cost-effective. However, the use of alternative substrates for paleoclimate reconstruction using fossil wood has not been evaluated.

Summary: Understanding tree growth and carbon sequestration is crucial for predicting forest feedback to climate change. The study introduces a new method using high-resolution X-ray computed tomography (HRXCT) to study tree xylogenesis, which has shown high accuracy in estimating relevant parameters across different species and wood structures. HRXCT proves to be an efficient avenue to investigate tree xylogenesis for a wide range of wood anatomies, structures, and species.

Summary: The study demonstrated that the cinnamaldehyde chitosan emulsion significantly improved the decay resistance of the treated wood by inhibiting the growth of decay fungi and altering their mycelial morphology. The formation of Schiff base in the treated wood enhanced the decay resistance, with better performance against brown-rot fungi compared to white-rot fungi. This suggests that the cinnamaldehyde chitosan emulsion can be effectively utilized as an environmentally friendly wood preservative.
