“…After soil disturbance, herbivory, and especially seedling herbivory, may become a crucial driver of vegetation dynamics and it can be determinant in facilitating non‐native success (Relva et al 2010). Although our results showed that herbivores hindered native establishment and did not affect non‐natives, we could not confirm findings of less herbivore damage on non‐native than on native plants (Cappuccino & Carpenter, 2005; Huang et al, 2020; Liu et al, 2007). In addition, we cannot exclude that the lower susceptibility of non‐natives might also arise from a ‘sampling effect’ (Loreau, 2000); i.e.…”

Aim Climate warming and increasing human disturbance are expected to promote non‐native plant invasions in mountain ecosystems. Although biological invasions are also expected to be modulated by biotic interactions, it is still not clear how invertebrate herbivores can affect plant invasion dynamics. Using a large manipulative experiment, we aimed at testing: (1) the effect of soil disturbance and elevation on native and non‐native plant communities, and (2) the effect of plant‐herbivore interactions, nitrogen deposition, and elevation in driving plant establishment after soil disturbance. Location European Alps, NE Italy. Taxon Vascular plants. Methods We selected remote, uninvaded dry semi‐natural grasslands along the core elevational range of non‐native plants in the European Alps (c. 100–1300 m) and manipulated soil disturbance, nitrogen deposition, and invertebrate herbivory. Then, we followed the natural establishment under real field conditions of both native and non‐native plants over one growing season. We used generalized mixed‐effects models to test the effects of the experimental treatments. Results Native and non‐native species showed contrasting responses to soil disturbance and elevation. Low elevations and disturbance promoted non‐native success, while affecting native species diversity negatively. Two‐thirds of the experimental sites acquired novel non‐natives after disturbance. Most of the observed non‐natives were not present in the surrounding vegetation as mature plants, indicating that propagules were able to reach even remote natural areas. While current N deposition levels did not affect plant establishment, we found that after disturbance invertebrate herbivory might play an important role in facilitating non‐native invasions by reducing native cover. Main conclusions Our findings show that highly resistant ecosystems such as continuous grasslands can be easily invaded once the resident vegetation has been removed, and that natural herbivory pressure from invertebrates might amplify the negative effects of disturbance on resident native species irrespective of elevation. Together, these results indicate increasing risks of future plant invasions on mountains under global change.

“…The overall differences between the invasive and native species in the 20 leaf traits were tested using within-study meta-analyses (van Kleunen et al 2011;Huang et al 2020). We firstly calculated the effect size (Hedges'd) and the corresponding sampling variance (v d ) of each trait for each species pair using the escalc function in R package metafor (Viechtbauer 2010).…”

“…The mechanisms underlying such non-native plant invasions have become one of the major topics in biology (Richardson and Pyšek 2006;Feng et al 2009;van Kleunen et al 2010;Li et al 2015;Hulme and Bernard-Verdier 2018). As a group, these invasive non-native (hereafter invasive) species may have distinct traits that allow them to compete with or even outcompete co-occurring native species (van Kleunen et al 2015b;Huang et al 2020).…”

Unfortunately, there were still large variations in the conclusions from the above-mentioned multi-species (dozens of or more) comparisons.…”

Many studies have attempted to test whether certain leaf traits are associated with invasive plants, resulting in discrepant conclusions that may be due to species-specificity. However, no effort has been made to test for effects of species identity on invasive-native comparisons. Here, we compared 20 leaf traits between 97 pairs of invasive and native plant species in seven disturbed sites along a southwest-to-northeast transect in China using phylogenetically controlled within-study meta-analyses. The invasive relative to the native species on average had significantly higher leaf nutrients concentrations, photosynthetic rates, photosynthetic nutrients- and energy-use efficiencies, leaf litter decomposition rates, and lower payback time and carbon-to-nitrogen ratios. However, these differences disappeared when comparing weakly invasive species with co-occurring natives and when comparing invasives with co-occurring widespread dominant natives. Furthermore, the magnitudes of the differences in some traits decreased or even reversed when a random subset of strongly to moderately invasive species was excluded from the species pool. Removing rare to common natives produced the same effect, while exclusion of weakly to moderately invasives and dominant to common natives enhanced the differences. Our study indicates that the results of invasive-native comparisons are species-specific, providing a possible explanation for discrepant results in previous studies, such that we may be unable to detect general patterns regarding traits promoting exotic plant invasions through multi-species comparisons.

“…There for, comparing the effects of exotic plants on native herbivorous insects and the effects of invasive plants on native herbivorous insects can better reveal the impacts of invasive plants on herbivores. Huang et al (2020) study found that invasive plants had lesser herbivory and structural defense and greater nutriment than non-invasive plants.…”
