“…Thus, the higher relative abundance of goldenrod under HDI may cause the extinction of some plant species to become extinct via the decrease in the relative abundance of total plant species within a community, leading to decreased stability of the plant community. However, this finding was less consistent with the results of a previous study (Valone & Balaban-Feld, 2018;Wang, Wu, Jiang, Zhou, Liu, & Lv, 2019), which showed that the invaders did not generate significant effects on plant community stability. The inconsistency between these results may be ascribed to the differences in the composition of plant communities, the type of plant communities, the size of plant communities, the species of invasive species, the climate type of the sample sites, and/or the duration of experimental period.…”

“…The diversity hypothesis proposes that greater levels of diversity can stabilize community fluctuations via the compensatory dynamics and complementary resource use Yang et al, 2012). This hypothesis has been confirmed in many earlier studies by the significantly positive diversity-stability correlation, especially in the small-scale planted communities (Cardinale et al, 2012;Gross et al, 2014;Tilman et al, 2014;Wang, Wu, Jiang, Zhou, Liu, & Lv, 2019). In contrast, the mass ratio hypothesis postulates that the spatial stability of plant communities was significantly positively related to the stability of the most dominant species (i.e., the species with the highest relative abundance) in a particular community (Grime, 1998;Hillebrand, Bennett, & Cadotte, 2008;Valone & Balaban-Feld, 2018).…”

“…All quadrats were examined to record the number of plant species, the number of individuals per plant species, and the total number of individuals of all plant species. For clonal plant species, the number of individuals was estimated primarily by evaluating the number of ramets because there is no substantial difference in the space occupied between one ramet of clonal plants and one individual of non‐clonal plants when they have an equivalent or similar height (Wang, Jiang, Liu, et al, ; Wang, Wu, Jiang, Zhou, & Du, ; Wang, Wu, Jiang, Zhou, Liu, & Lv, ).…”

“…To date, goldenrod has colonized diversified ecosystems, including urban areas, meadows and pastures, farmlands and wastelands, roadsides, ditches, and upland forests, etc. (Abhilasha et al, 2008;Wang, Wu, Jiang, Zhou, Liu, & Lv, 2019;Yang et al, 2008).…”

Understanding the impacts of invaders on plant taxonomic diversity and community stability is significant for understanding the mechanisms underlying successful invasion. This study explored the impacts of the invasive plant Canada goldenrod (Solidago canadensis L.; goldenrod hereafter) with different degrees of invasion on plant taxonomic diversity and community stability by conducting a comparative study in eastern China. Degree of invasion was divided into the following categories, low (<35%, LDI), moderate (35–75%, MDI), and high (>75%, HDI), on the basis of the relative abundance of goldenrod in the invaded plant communities. Plant diversity, dominance, richness, and plant community stability noticeably decreased under HDI but plant diversity and dominance dramatically increased under LDI compared with the adjacent uninvaded plant communities. Plant diversity, dominance, richness, and community stability markedly declined as the degree of goldenrod invasion increased in the invaded plant communities. The greater plant diversity and dominance observed under LDI may be primarily driven by the passenger effects rather than a driving force of the presence of goldenrod. The greater competitive superiority of goldenrod over coexisting native plants under HDI might allow for invasion and enhance the risk of stochastic local extinction of several native species. A significantly positive diversity‐stability relationship was observed, which may explain the underlying mechanisms for the decreased plant community stability and drastic decline in plant diversity under HDI. Accordingly, the degree of invasion of goldenrod plays an important role in the variation of plant taxonomic diversity and community stability in eastern China.

“…Presently, invasive alien species (IAS) have triggered remarkable effects on the ecosystem services and the corresponding stability of indigenous ecosystems [1][2][3][4][5][6][7]. Hence, plant ecologists are particularly interested in estimating the mechanism driving the successful invasion over the years.…”

Invasive alien species (IAS) can distinctly inhibit seed germination and seedling growth performance (SGeSGrP) of indigenous species via the allelopathy. The progressively increased drought stress can potentially affect the allelopathy of IAS. Thus, it is significant to illustrate the allelopathy of IAS on SGeSGrP of indigenous species under drought stress to obtain a deeper elucidation for the main driving mechanism attributed to the successful invasion. This study attempts to identify the allelopathy of IAS Solidago canadensis L. (goldenrod; using leaf extracts) on SGeSGrP of the indigenous species Lactuca sativa L. (lettuce) under drought stress [mimicked by Polyethylene glycol-6000 (PEG 6000)]. Goldenrod leaf extracts (low concentration) obviously reduced seed germination performance of lettuce but goldenrod leaf extracts (high concentration) notably reduced seedling growth performance of lettuce. Goldenrod leaf extracts (low concentration) also interestingly awarded an optimistic effect on the competitive ability for sunlight acquisition as well as water and inorganic salt acquisition, plant growing ability, and plant water content of lettuce. PEG 6000 dramatically inhibited the competitive ability for sunlight acquisition as well as water and inorganic salt acquisition of lettuce. PEG 6000 also noticeably enhanced the allelopathy of goldenrod leaf extracts on the germination speed and vitality, competitive ability for sunlight acquisition as well as water and inorganic salt acquisition, leaf photosynthetic area, and plant growing ability of lettuce. Thus, drought stress may be advantageous to the advance of goldenrod invasion process mainly via the oppressed SGeSGrP of indigenous species mediated by the enhanced allelopathy.

Reproductive allocation of Solidago canadensis L. plays a key role in its invasiveness across a gradient of invasion degrees

Reproductive allocation (RA) plays a vital role in the development of ecological strategies during the life cycle of plant species. Invasive alien plants (IAP) may exist at various invasion degrees across a gradient of the colonization process with several grades of relative abundances in the occupied environments. The progressive variation in the invasion degree of IAP has the potential to modify their RA strategy. This study purposes of estimating the RA strategy of the IAP Solidago canadensis L. and the correlations among RA of S. canadensis, the invasion intensity of S. canadensis, the invasiveness of S. canadensis, and the community invasibility across a gradient of invasion degrees by using the field sampling experiment. The height and relative abundance of S. canadensis did not remarkably affect its RA. The RA of S. canadensis was positively related to its reproductive biomass and total biomass. The key reason may be that plant individuals with higher total biomass can allocate more resources into sexual reproduction. The RA of S. canadensis was positively related to its invasiveness. Thus, the RA of S. canadensis may be crucial to its invasiveness.
