Summary: Ongoing global warming promotes the spread of thermo-tolerant plant species, including plants with a high allergenic risk like common ragweed. To investigate the effects of temperature increase on plant traits and biochemical processes related to allergenicity, a phytotron chamber experiment was conducted. The results showed that elevated temperature increased plant height, size of male inflorescences, duration of pollen release, and delayed pollen release, while elevated NO2 concentration induced pollen release and enhanced allergenicity. Combined treatment of elevated temperature and NO2 resulted in the highest allergenicity.

Summary: This study explored the regulation of autotoxicity on intraspecific density of Ambrosia artemisiifolia and Ambrosia trifida. The results showed that both plants have significant autotoxicity, with chlorogenic acid, caffeic acid, p-coumaric acid, and vanillin identified as the main autotoxins. Additionally, the germination recovery rate of seeds increased with the inhibition degree of autotoxins treatment after washing with water.

Summary: Predicting the invasion areas of Ambrosia species in Asia is important for early detection and preventive actions. Based on species distribution models and future climate predictions, it was found that Ambrosia artemisiifolia may shift its range southward in China, while A. trifida is predicted to decrease its potential establishment and A. psilostachya may expand its range.

Summary: Ambrosia pollen contains strong allergens that can cause allergic reactions. The concentration and annual sum of Ambrosia pollen are higher in Ivano-Frankivsk than in Lublin, indicating a higher allergy risk in Ukraine. Contact with the secretory product of Ambrosia artemisiifolia L. can lead to dermatitis in sensitive individuals.

Summary: Ambrosia artemisiifolia, an invasive plant, has been found to release four sesquiterpenes that have inhibitory effects on native and model plants. Compound 1 shows the strongest inhibitory effect. The study also reveals the preliminary action mechanism of compound 1 and the release pathway of compounds 1-3.

Summary: This study identified the chemical composition of sesquiterpenoids in the inflorescence of A. artemisiifolia and found that these compounds have allelopathic effects on the growth of wheat seedlings, providing further insight into the chemical basis of allelopathy in A. artemisiifolia.

Summary: Assessing the capacity of weeds to develop herbicide resistance before it occurs in the field is crucial for effective chemical weed control. This study used herbicide selection and controlled crosses to accelerate the evolution of resistance to two commonly used herbicides in Ambrosia artemisiifolia. The results showed that non-target-site-based resistance (NTSR) to herbicides was significantly increased in just two generations of selection. NTSR to the tested herbicides emerged and was reinforced in subsequent generations. Further bioassays confirmed the emergence of resistance to imazamox and/or tribenuron in multiple A. artemisiifolia populations. NTSR was found to be the predominant type of resistance, with only one population showing a mutant ALS allele in addition to NTSR. This study highlights the importance of pre-emptive assessment of resistance evolution in weed populations.

Summary: Low temperatures affect the establishment of newly introduced species, but increased cold tolerance can promote their adaptability. This study found that cold stress improves the accumulation of cryoprotectants and cold tolerance in Ambrosia artemisiifolia, an invasive alien species. Furthermore, feeding on cold-hardened A. artemisiifolia enhances the cold tolerance of its biological control agent, Ophraella communa.

Summary: In this study, a long-term field experiment was conducted to compare the microbial community compositions in the rhizosphere soil of invasive common ragweed and two native plants. The bacterial and fungal community compositions differed significantly between common ragweed and the two native plants. Invasion by common ragweed selectively accumulated microorganisms that can enhance carbon and nitrogen cycling and the absorption of phosphorus in the rhizosphere environment. Furthermore, microbial inoculants from common ragweed rhizosphere promoted the growth of both common ragweed and Setaria viridis.

Summary: The study analyzed the chemical composition of Ambrosia artemisiifolia essential oil, which is rich in sesquiterpenes, and found it to have significant phytotoxic activities against both monocot and dicot plants. The essential oil inhibited seed germination, seedling development, and root cell viability, while also causing visible injury to leaves and a decrease in chlorophyll content in tested weeds. Additionally, the essential oil altered root tip cells by decreasing the mitotic index and increasing chromosomal aberrations.

Summary: This study investigated the relative contributions of phenotypic plasticity and local adaptation to the performance of the invasive plant Ambrosia artemisiifolia under different soil nitrogen levels. The results showed significant interpopulation genetic differentiation and plastic responses in various traits of A. artemisiifolia across nitrogen treatments. Additionally, individuals from higher latitudes exhibited different growth patterns regardless of nitrogen treatment, while other trait responses depended on the nitrogen levels. Overall, these findings suggest that rapid adaptive evolution and phenotypic plasticity may jointly contribute to invasiveness in A. artemisiifolia under varying nitrogen availability, supporting the idea that invasive plants can colonize diverse environmental conditions.

Summary: High-quality greenspace is associated with promoting health and reducing stress, but the impact of poor quality greenspaces, such as vacant lots, on human health remains less understood. The existing research lacks a systematic review on this topic, and future studies need to explore the effects of vacant lots on health in more depth and breadth.

Summary: This study investigates the impact of Bacillus community, a type of spore-forming bacteria, on the competitive advantage of invasive plants. The results indicate that the relative abundance of Bacillus megaterium in the rhizosphere soil of the invasive plant is significantly higher than in the native plant. In addition, inoculation with B. megaterium isolated from both the invasive and native plants enhances the relative competitiveness of the invasive plant and inhibits that of the native plant. These findings contribute to understanding the role of Bacillus community in the invasion of invasive plants.

Summary: Collaborative processes of co-production are effective in improving the quality and support for design outcomes. In spatial design and planning, co-design often involves engaging community members in the design of their local environment. Decision support systems play a crucial role in supporting co-design of landscapes.
