The impact of a native dominant plant, <i>Euphorbia jolkin</i> <i>i</i> <i>i</i> , on plant–flower visitor networks and pollen deposition on stigmas of co‐flowering species in subalpine meadows of Shangri‐La, SW China

Anthropogenic activity can modify the distribution of species abundance in a community leading to appearance new dominant species. While many studies report that an alien plant which becomes increasingly change composition, plant–pollinator network structure and reproductive output native species, much less is known about become their communities. Euphorbia jolkinii Boissier (Euphorbia, hereafter) has over-grazed meadows Shangri-La, SW China. During flowering season over 2 years, we quantified impact on richness flower visitor 12 subalpine along gradient dominance. We also evaluated floral preferences visitors, interaction evenness plant–flower networks deposition pollen stigmas two co-flowering (Gentiana chungtienensis Anemone rupestris) each meadow. The visitors non-Euphorbia plants was negatively correlated with As proportion increases, decreased, while other increased. Interaction decreased as Furthermore, conspecific one studied, G. chungtienensis, Synthesis. There appears be little substantive difference between newly impacts reported for This lack suggests dominance, addition origin (alien vs. native), could play important role influencing functioning finding considerable implications restoration ecology. Thus, communities where natural dominance order been changed due anthropogenic may not considered problem all are native—in reality though, they damaged invaded by
