Summary: The purpose of this review is to define which silvicultural systems and forest operations can have an influence on forest tree biodiversity by summarizing the findings of nearly 60 papers published in the last ten years (2013-2022). The findings suggest that selective logging and retention forestry are suitable forms of intervention that have a limited impact on tree biodiversity in natural forest ecosystems with high structural complexity. Thinning and coppicing are effective treatments for managing tree biodiversity, but should be carefully regulated to avoid negative impacts.

Summary: The standing skyline is a common cable logging configuration, but the assumption of constant tagline length in payload analysis severely limits the skyline load-carrying capacity. Researchers suggest that smart carriage technology and variable length tagline could significantly increase log load capacity and logging productivity. By using a methodology for estimating log load capacity with variable tagline length, it is illustrated that increases of 30-40% in log load are possible.

Summary: This paper presents a review on the skid resistance of cement concrete pavement in highway tunnel, summarizing the pavement working environment and discussing the tire-pavement friction mechanism, friction measurement methods, pavement skid resistance, pavement surface texture measurement methods, and anti-skid evaluation models. The importance of pavement texture morphology and tire dynamics models in investigating the micro-contact and simulating tire dynamics is emphasized. The paper also provides an overview of anti-skid methods for cement concrete pavement, including resurfacing techniques and anti-skid overlays. The Novachip ultra-thin wearing layer is identified as a more promising option for highway tunnel pavement.

Summary: If there are specific paths between any two vertices in a digraph D, D may be weakly Hamiltonian-connected; if there are two specific paths simultaneously between two vertices, D may be strongly Hamiltonian-connected. Thomassen characterized weakly Hamiltonian-connected tournaments and proved that every 4-connected tournament is strongly Hamiltonian-connected in 1980. Additionally, the study also discussed the weakly and strongly trail-connected digraphs and their relationships in tournaments.

Summary: Forest soil compaction caused by heavy machines can lead to ecosystem degradation, reduced site productivity, and increased greenhouse gas emissions. Recent studies have shown the potential of black alder in alleviating soil compaction, but this study found that black alder did not have a positive impact on soil recovery and may worsen the greenhouse gas balance of the forest stand.

Summary: This study investigates the effects of erosion degradation and long-term manure fertilization on soil properties and crop yield in Northeast China. Results show that erosion degradation and manure fertilization have lasting impacts on soil physical structure throughout the soil profile, while their effects on soil nutrient properties are focused in shallow layers. Manure fertilization significantly improves soil functional index (ISI) and maize yield for degraded soils. Erosion degradation has a greater influence on ISI and maize yield than manure fertilization.

Summary: This study investigates the structural strength of the Loess-Paleosol Sequence (LPS) and finds that the strength tends to increase with burial depth, with the loess layer weaker than the paleosol layer. The microstructure of the LPS also undergoes significant transformations with increased burial depth, transitioning from an overhead structure to a matrix structure. These findings highlight the importance of climate conditions on the structural strength of the LPS.

Summary: This study aimed to evaluate the impact of long-term nutrient management practices on P fractions and P adsorption-desorption behaviour of an acid soil with a soybean-wheat cropping system. The findings revealed that amorphous Fe and Al, which play a significant role in P fixation, increased due to cultivation. The NPK+Lime treatment offered the most balanced approach, improving both crop yield and P uptake while effectively managing P dynamics in the soil. On the contrary, long-term application of NPK+FYM in an acid soil may result in faster P saturation of adsorption sites and increase the chances of leaching and eutrophication. Tailored P fertilization strategies should be developed to better utilize the PFe and PAl fractions and supplementing applied P.
