“…The height and diameter performance of S. canadensis was worst at the 50-60% invasion stage, probably due to peak plant density (S3A3 and S3A2) at this stage, leaving stem growth constrained by less space and resources available (Brooks and Crowe 2018). Likewise, Cheng et al (2021a) found that the height of S. canadensis changed substantially with an increasing invasion degree, while its leaf-related traits of leaf width, length, area, chlorophyll and nitrogen content did not. The above results suggest stem-related traits are more sensitive than leaf-related traits to interspecific and/or intraspecific competition, probably due to the leaf organ being capable of greater phenotypic plasticity.…”

“…Several studies have demonstrated that phenotypic traits of invasive species can change with the environment and/or invasion stage (Cheng et al 2021a;Uddin and Robinson 2018;Verlinden et al 2014;Zhang et al 2020), but how the invasion process changes with the environment remains understudied. Here, we performed a direct test of the impact of environmental change upon the performance and competitiveness of S. canadensis, under different degrees of invasion, to reveal how environmental change affects the invasion process of S. canadensis.…”

Background Invasive species can threaten native diversity and alter ecosystem processes while interacting with other components of global environmental change. Invasive plants are becoming increasingly problematic and this can be stimulated by changes in the environment. However, existing studies have primarily investigated the effects of environmental change on a specific stage of plant invasion rather than the continuous invasion process. Methods A space-for-time substitution experiment was performed to investigate how warming and nitrogen deposition affects the invasion process of a plant. Specifically, different ratios of invasive Solidago canadensis L. to native Artemisia argyi Levl. et Van were employed as a proxy to represent successive levels of invasion. A total of seven treatments were applied in the experiment: ambient (CK), N addition (+ 5, + 12 g m−2 year−1), warming (+ 1.15, + 1.86 °C) and their interaction (5 g N m−2 year−1 + 1.15 °C, 12 g N m−2 year−1 + 1.86 °C). The growth performance and competitiveness of S. canadensis were investigated. Results The competitiveness of Solidago canadensis decreased linearly with its invasion degree (p < 0.05). Non-linear regression showed that S. canadensis invasion levels of 53%, 53%, 68%, 55% and 58% were the critical thresholds for shifting the direction or magnitude of chlorophyll, leaf nitrogen, leaf shape index, diameter, and root/shoot ratio, respectively. Compared with the ambient treatment (CK, no warming and no N addition), the diameter, height, biomass and relative competitiveness of S. canadensis were each limited by warming, to a certain extent, whereas these and the above parameters were significantly increased by nitrogen deposition. The interaction of increased temperature and nitrogen deposition led to significant increases in the growth and competitiveness of S. canadensis, and this effect was detected in every stage of the invasion, throughout the invasion process. Conclusions Environmental change might have a continuous, progressive, and augmentative effect on the phenotypic traits of S. canadensis. This study provides fairly robust evidence that environmental change promotes the invasion process of S. canadensis in general, not simply in specific stages. In the future, rather than focusing on specific stages, experimental studies should consider examining invasion on a broader scale.

Effects of surrounding landscape on the performance of Solidago canadensis L. and plant functional diversity on heavily invaded post-agricultural wastelands

High invasiveness and well-documented negative impact on biodiversity and ecosystem functioning make Solidago canadensis L. a species of global concern. Despite a good understanding of the driving factors of its invasions, it remains unclear how the surrounding landscape may shape invasion success of this species in human-transformed ecosystems. In our study, we investigated the impacts of different landscape features in the proximity of early successional wastelands on S. canadensis biomass allocation patterns. Further, we examined the relationships between the surrounding landscape, S. canadensis cover, and plant functional diversity, used as a supportive approach for the explanation of mechanisms underlying successful S. canadensis invasion. We found that increasing river net length had positive impacts on S. canadensis rhizome, stem, and total above ground biomass, but negative effects on leaf biomass, indicating that vegetative spread may perform the dominant role in shaping the competitiveness of this invader in riverine landscapes. A higher proportion of arable lands positively influenced S. canadensis above ground and flower biomass; thus promoting S. canadensis invasion in agricultural landscapes with the prominent role of habitat filtering in shaping vegetation structure. Concerning an increasing proportion of settlements, flower biomass was higher and leaf biomass was lower, thereby influencing S. canadensis reproductive potential, maximizing the odds for survival, and indicating high adaptability to exist in an urban landscape. We demonstrated high context-dependency of relationships between functional diversity components and surrounding landscape, strongly influenced by S. canadensis cover, while the effects of surrounding landscape composition per se were of lower importance. Investigating the relationships between the surrounding landscape, invasive species performance, and plant functional diversity, may constitute a powerful tool for the monitoring, controlling, and predicting of invasion progress, as well as the assessment of ecosystem invasibility.

Spontaneous hybrids between alien and native plant species are alien taxa and they threaten native biodiversity due to their high competitive ability or introgression. Thus, we tested the effect of soil conditions, elevation and type of ramet clusters (clonal clumps of shoots) on sexual and asexual ramets of Solidago × niederederi, a hybrid between the invasive alien S. canadensis and the native S. virgaurea. We also tested the relationships between the size of sexual ramets and habitat conditions in the hybrid and its parental species, based on ten sites in NE and S Poland, respectively. The hybrid and its parental species occurred on mineral soils with a wide range of textures (sand, loamy sand, sandy loam, silty loam and loam) and pH (from strongly acidic to slightly alkaline). Sexual ramet clusters dominated in S. × niederederi populations, while the total number of ramets was highest in mixed ramet clusters. The cluster × site interaction had a significant effect on the length and biomass of sexual ramets in hybrid populations. Moreover, we found a significant effect of the taxon × site interaction in the case of biomass of sexual ramets and synflorescences (capitula arranged in panicles). Based on the biomass of sexual shoots and synflorescences, the competitive abilities of the hybrid may be more or less similar to S. canadensis or S. virgaurea albeit depending on site conditions.
