Summary: The expansion of complex global supply chains has led to an increased role of global trade in environmental deterioration. This study explores the influence of the carbon trade balance on CO2 emissions in N11 countries from 1990 to 2020, considering variables such as renewable/fossil energy consumption, financial development, and urbanization growth. The results suggest that all the variables investigated have a negative impact on the environment in the long run, while renewable energy helps alleviate CO2 emissions.

Summary: Continuous cover forestry (CCF) is considered as an eco-friendly choice for drained peatlands. However, CCF management faces challenges in tree growth, especially in suppressed trees after selection harvesting. This study aimed to quantify the delayed stem diameter growth response in suppressed Norway spruce trees compared to dominant ones after selection harvesting, and to examine the immediate effect of harvesting on carbon assimilation. The results showed that the suppressed trees experienced a delayed growth response, while carbon uptake increased immediately after selection harvesting.

Summary: The study revealed that urban trees are affected by urbanization with varying degrees of drought tolerance. Among them, Robinia pseudoacacia and Platanus x acerifolia are less affected by urbanization and show the highest drought tolerance in urban environments.

Summary: Forest tree communities are shaped by interactions between phenotypes and environments. Functional traits provide insights into plant tradeoffs. The relationships between tree crown-stem diameter and tree height-stem diameter are coordinated with functional trait tradeoff axes. Interspecific variation in tree architecture is driven by variation in allometric intercepts rather than slopes.

Summary: In this study, we evaluated the effects of light intensity and root deformation on the prediction capacity of Genipa americana seedling biomass using allometric models. We found that both factors influenced the relationship between biomass and stem diameter (D) and stem diameter squared multiplied by height (DH). The best allometric equation was obtained using stem diameter as the predictor variable.

Summary: This study investigates how the crown features of different tree species influence wind load and concludes that Ficus concinna, Dracontomelon duperreanum, Ormosia pinnata, and Bischofia javanica are recommended for urban greening due to their ability to withstand smaller wind load. On the other hand, Schefflera macrostachya, Acacia confusa, and Khaya senegalensis are not suitable. Additionally, crown features such as crown horizontal ratio, windward side projection, and porosity ratio are found to be important in estimating wind load.

Summary: Accurate estimation of tree diameter, height, volume, and biomass is crucial for economic and ecological applications. This study presents exponential equations for predicting these parameters in planted stands of different tree species using varying levels of input data. The models perform well, especially when height and crown area are known, and can be applied across a wide range of ages and densities.

Summary: Fibrin is commonly used in wound coverings, surgical glues, and cell delivery due to its affordability, cytocompatibility, and ability to modulate angiogenesis and inflammation. However, its rapid degradation rate limits its use in 3D cell culture and tissue engineering. Through additional crosslinking of fibrin gels and adjusting salt concentrations, the degradation rate of fibrin was successfully slowed down without affecting cell viability.

Summary: This study found that fruit size in Camellia japonica influences shoot structure, resulting in differences in shoot characteristics across different latitudes. However, the overall traits of 1-year-old shoots did not vary significantly across latitudes, indicating that natural selection on fruit size may influence some traits of Corner's rules in C. japonica, but not all.

Summary: This study used continuous high-resolution measurements of stem diameter to investigate the effect of climate on the daily and seasonal growth dynamics of Quercus faginea in central Portugal. The results showed that the species relies on deep soil water reserves and remains physiologically active during summer drought.

Summary: Collecting and managing individual tree data is crucial for green sustainability strategies. However, it is challenging and costly to collect data on trees located on private land. This study explores the potential of a supervised machine learning algorithm as a cost-efficient method to understand tree sizes and locations on private land, and discusses the benefits of this approach for sustainable urban greening. The precision and recall of detecting the urban forest are also reported.

Summary: This study aims to improve the estimation of forest inventory metrics in mixed forests by integrating multispectral imagery with lidar models. Although the addition of multispectral imagery does not substantially enhance the accuracy of estimating BA, volume, and AGB, lidar variables remain the most important ones.

Summary: As per capita income increases, there are significant changes in both environmental quality and income inequality, prompting attention to the relationship between the two. Research shows that income inequality has a significant positive impact on environmental pollution. Additionally, there is an inverted U-shaped relationship between income inequality and environmental quality, with per capita income serving as an intermediary variable.

Summary: This study investigates the most important success factors in urban forest governance according to Canadian experts, as well as how experts would like to evaluate these factors. Experts identified financial resources, data-driven decision making, and goals and objectives as the most important factors. They also highlighted governance challenges related to funding, support from various stakeholders, development pressures, and establishing laws and policies.

Summary: The Greening Soweto tree-planting project in Johannesburg aimed to extend the benefits of the 2010 FIFA World Cup by planting 200,000 trees, but with a survival rate of only 43%. The project focused on planting trees in areas with fewer trees, transforming disadvantaged regions of the city by beautifying streets and developing parks for residents to be proud of.
