“…Maintaining the stability of the biogeochemical cycle of N and P is therefore of great significance to entire ecosystems. However, anthropogenic-mediated disturbances of N and P can have a major influence on the structure and functioning of ecosystems; for example, excessive emissions of N and P change the element compositions and stoichiometries in regional ecosystems and the relationships between species composition and ecological processes [4][5][6]. At the same time, invasive alien species (IAS) also pose a serious threaten to ecosystems, which may cause disturbances in biogenic element cycles, reduced biodiversity, ecosystem degradation, and even destruction of the original ecosystem [7].…”

Plant invasion is significantly affected by environmental factors in the recipient habitats and affects the stability and sustainable development of society. The invasiveness of alien plants may be increased by anthropogenic-mediated disturbances, such as fluctuations in nutrients caused by excessive emissions of nitrogen (N) and phosphorus (P). To improve our understanding of the interactions between N and P fluctuations and invasive alien plants, the current report focuses on the biogeochemical behavior of N and P among invasive alien plants, native plants, and the soil within the plant–soil ecosystem. Our research, together with a synthesis of the literature, shows that fluctuations in N and P resources provide more opportunities and competitiveness for plant invasion. At the same time, the biogeochemical cycles of N and P are promoted because of their efficient and increased utilization and rate of release by invasive alien plants. However, there is no consensus on whether the N and P compositions of invasive species are different from those of the natives in their habitat. Quantitative studies that compare N and P contents in plant, litter, and soil between native plant communities and invaded communities on a global scale are an indispensable area of research focus for the future.

“…S. gigantea has spread throughout Europe since the nineteenth century and it currently is permanently established in many natural and anthropogenic habitats (Tokarska-Guzik et al 2012;Szymura et al 2018); therefore, its suitability for application, e.g., in bioindication as well as its contribution to metal transfer to food chains are worth consideration. In addition, biogeochemical studies may shed more light on the explanation of its invasiveness: it has already been suggested that increased environmental pollution provides more opportunities for the invasion of alien species (Li et al 2021) and that invasive plants in metal-polluted urban environments may be even more successful than in natural sites due to the better adaptation or tolerance to stressful conditions compared to native plants (Yang et al 2007;Sołtysiak et al 2014). According to Li et al (2021) invasive plants showed self-protective mechanisms when exposed to heavy metals and metal pollution may favor plant invasion due to the widespread higher tolerance of invasive plants to heavy metals compared to native species.…”

Invasive species usually grow in human-disturbed habitats including urban areas where they face numerous pollutants, including metals that attract special attention due to their non-degradability and high accumulation potential. In this study we evaluated the contents of potentially toxic metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in the invasive species Solidago gigantea. The strategy adopted by S. gigantea in response to excess trace metals in the soil was assessed. Metal contents were determined using atomic absorption spectrometry in leaves, stems and roots of S. gigantea collected from 30 sites located in areas affected by various human activities. Metal concentrations (total and bioavailable fraction) were also determined in corresponding soil samples. Results showed that S. gigantea was able to inhabit strongly polluted sites. High Bioaccumulation Factor but low Translocation Factor values for Cd, Cu, Cr, Fe, Ni show that S. gigantea takes up metals from soil but reduces their transport to the aboveground parts and could be classified as a metal-tolerant species with exclusion strategy. The Bioaccumulation Factor values for Cd, Cu, Cr, Pb and Zn were remarkably higher in plants growing in areas characterized by low metal concentrations in soil compared to the ones affected by industry, with high metal concentrations. This suggests that S. gigantea that grows in polluted areas can reduce the uptake of potentially toxic metals. Regardless of the limited transport of metals to the aboveground organs, the content of metals in S. gigantea leaves differed between areas differing in human impact and the species can be used as a biomonitor.

“…Consequently, F. japonica outcompetes native plants for resources such as light and nutrients by forming dense stands and altering the soil nitrogen composition, finally reducing biodiversity [ 17 ]. The success of invasive plants is often related to a higher tolerance toward heavy metals, relative to native species [ 18 ]. In support of this general statement, members of the genus Fallopia have been shown to be tolerant to heavy metal contamination including copper [ 19 ], which is accumulated mainly in roots ( F. convolvulus [ 20 ], F. japonica [ 21 , 22 , 23 ]).…”

Copper accumulating in stream sediments can be transported to adjacent riparian habitats by flooding. Although being an essential element for plants, copper is toxic at high concentrations and restricts, among other things, plant growth. Besides copper, invasive plants, such as Fallopia japonica, which are known to be tolerant toward heavy metals, modify riparian habitats. If the tolerance of F. japonica is higher compared to native plants, this could accelerate invasion under high heavy metal stress. Therefore, we aimed to compare the effect of copper on two common riparian plants, the invasive F. japonica and the native Urtica dioica. We performed a pot experiment with a gradient from 0 to 2430 mg kg−1 of soil copper. We hypothesized that (i) negative effects on plant growth increase with increasing soil copper concentrations with F. japonica being less affected and (ii) accumulating higher amounts of copper in plant tissues compared to U. dioica. In support of our first hypothesis, growth (height, leaf number) and biomass (above- and belowground) of F. japonica were impacted at the 810 mg kg−1 treatment, while the growth of U. dioica was already impacted at 270 mg kg−1. Due to 100% mortality of plants, the 2430 mg kg−1 treatment was omitted from the analysis. In contrast, chlorophyll content slightly increased with increasing copper treatment for both species. While U. dioica accumulated more copper in total, the copper uptake by F. japonica increased more strongly after exposure compared to the control. In the 810 mg kg−1 treatment, copper concentrations in F. japonica were up to 2238% higher than in the control but only up to 634% higher in U. dioica. Our results indicate that F. japonica might be able to more efficiently detoxify internal copper concentrations controlling heavy metal effects compared to the native species. This could give F. japonica a competitive advantage particularly in polluted areas, facilitating its invasion success.
