Summary: Copper oxide nanoparticles were synthesized using a sustainable and environmentally friendly green approach method. They have a spherical morphology, a face-centered cubic structure, and exhibit UV-vis absorption at 412 nm. The nanoparticles were obtained by utilizing an aqueous petal extract of Wedelia trilobata as a reducing agent. They show functional groups corresponding to Cu - O stretching vibrations at 436.09 cm(-1) and 456.50 cm(-1) as detected by FT-IR. The nanoparticles have a crystalline size of 4.2 nm according to DLS measurements and exhibit stable zeta potential. Their antibacterial activity was tested against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. Additionally, their antioxidant activity was assessed using a DPPH assay and their denaturation activity was evaluated using BSA protein.

Summary: In China, the invasive plant species Wedelia trilobata (WT) is a significant concern. This study aimed to predict the growth of WT and its native plant species Wedelia chinensis (WC) using different efficient methods under different environmental conditions. Multiple linear regression (MLR) and artificial neural network (ANN) models were constructed to predict dry weight based on various morphological traits. The ANN model showed higher accuracy compared to the MLR model. Sensitivity analysis revealed that plant height and number of nodes were the most important variables supporting WT and WC growth under submergence and eutrophication conditions. This study provides a new method to control the spread of invasive plant species in different habitats.

Summary: Phosphorus (P) is a vital macronutrient for all life on Earth and plays a crucial role in plant growth and yield. However, P deficiency is a common problem in terrestrial ecosystems worldwide. The use of chemical phosphate fertilizer has limitations due to its non-renewable raw materials and adverse effects on the environment. Therefore, finding alternative strategies, such as phosphate-solubilizing bacteria (PSB), to meet plant P demand is important. This article reviews the biogeochemical P cycling in soil systems, explores the use of PSB to alleviate global P resource shortage, discusses the advances in multi-omics technologies, and analyzes the multiple roles of PSB inoculants in sustainable agricultural practices. The authors propose that further research is needed to better understand the interactive mechanisms between PSB, rhizosphere microbiota, and plants in order to maximize the efficacy of PSB as P activators.

Summary: Avena sativa and Sinapis alba are viable options for phytoremediation of soil contaminated with Cd2+, with Avena sativa showing greater ability to accumulate Cd2+ in the roots. Although cellulose fertilization stimulated microbial proliferation in Cd2+-contaminated soil, it did not mitigate the adverse effects of Cd2+ on bacterial diversity. Core microbiome of the soils included bacteria from the genera Sphingomonas, Sphingobium, Achromobacter, and Pseudomonas.

Summary: Adding lime significantly reduces the exchangeable fraction of copper and cadmium in soil, while plant species can decrease runoff generation. Different copper-tolerant plant species have varying effects on water-soluble copper concentrations, but combined remediation effectively reduces copper erosion to aquatic ecosystems.

Summary: This study investigates the use of phytoremediation, specifically focusing on Mediterranean plants, to reduce heavy metal concentrations in contaminated soils. Based on a review of 166 research studies, the findings suggest that phytoremediation is a sustainable and affordable option, particularly for developing countries. While non-native plant species may be preferred for their metal tolerance mechanisms, they can also pose risks to local ecosystems and should be carefully considered.

Summary: The tolerance of Eichhornia crassipes to cadmium (Cd) is dose-dependent, with Cd stimulating stomatal opening and increasing cell tightness ratio. Moderate levels of Cd stimulate the release of certain biochemical substances and the activity of antioxidant compounds in E. crassipes, enhancing its tolerance to Cd.

Summary: The excessive copper resulting from industrial development and population expansion in recent decades leads to environmental pollution, negatively affecting plant growth and photosynthesis. The study found that Eichhornia crassipes could be used as a phytoremediation agent for Cu2+ pollution in aquatic environments, especially in sites with low pollution levels. The tolerance of E. crassipes to Cu2+ is dependent on osmotic regulation, anti-lipid peroxidation, and improved antioxidant properties.

Summary: A model combining metabolic scaling, Michaelis-Menten equation, and elemental stoichiometry was developed to predict the relationship between plant photosynthetic rate and biomass. The results showed that nutrients play a direct role in the allocation of plant biomass and photosynthetic investment, affecting photosynthesis-biomass allometry. This model was found to outperform the traditional metabolic scaling model in explaining the photosynthesis-biomass relationship.

Summary: Urban woodlands play a key role in supporting sustainability of urban systems, with the distribution and dynamics of tree canopy cover having a significant impact on the size-density pattern of vegetation. Optimal planting density under different canopy cover levels can be determined through ecological size-density allometry, with middle canopy cover and low understory herb density proposed as an optimal management strategy for maintaining high ecosystem services and functioning of urban woodlands.

Summary: Through studying the physiological indexes, heavy metal contents, and accumulation of two different plant species, Pennisetum sinese and Lolium perenne, under different planting patterns, it was found that intercropping resulted in higher heavy metal accumulation compared to monoculture. P. sinese had higher accumulation amounts of Pb, Cd, Cu, and Zn, indicating its suitability for phytoremediation of heavy metal-contaminated soils.

Summary: Identification and prediction of potentially contaminated sites (PCS) were conducted using a fuzzy matching algorithm and risk probability zoning strategy in the Yangtze River Delta. The results showed a significant increase in the number of PCS in the region, driven by socio-economic and physical geography factors. The risk prediction indicated a high proportion of low-risk probability pixels in the future, demonstrating the effectiveness of local government efforts in managing and controlling contaminated sites.

Summary: Understory vegetation plays a crucial role in urban forests by providing habitat and supporting plant and animal biodiversity. However, the factors and mechanisms of nonnative species invasion in the understory layers of urban forests are not well understood. In this study, we examined the community structure and composition of understory vegetation in 16 urban forests in Shanghai, China. We found that socio-economic variables, native species cover, and overstory canopy cover were the primary drivers of nonnative species invasion. These findings have important implications for the management and control of understory invasions in urban forests.
