title: Data from: Spatial mid-domain effect overrides climate, soil properties and microbes on a cosmopolitan non-native plant across elevation

description: Climate warming and anthropogenic activities have led to an increase in
 the prevalence of non-native plants in mountainous regions that previously
 exhibited limited occurrences. This phenomenon has resulted in detrimental
 effects on endemic plants and ecosystem functions. However, the variation
 in traits of non-native plants that successfully spread to high
 elevations, as well as the underlying drivers of these changes, remains
 poorly understood. In this study, we use Erigeron annuus, a cosmopolitan
 non-native plant that has invaded high elevations, as our model to explore
 its individual biomass pattern along a 1900 m elevation gradient. We also
 contrast this pattern with that of the native Artemisia lavandulifolia,
 which has the same distribution range as E. annuus. We found that the
 biomass of E. annuus displayed a hump-shape pattern along elevation, while
 the biomass of the native A. lavandulifolia gradually decreased with
 increasing elevation. By evaluating the effects of climate variables, soil
 properties, rhizosphere fungal communities, and their spatial mid-domain
 effect (i.e., geographic limitation) on plant biomass, we found that the
 biomass of E. annuus was primarily influenced by the spatial mid-domain
 effect, while the biomass of A. lavandulifolia resulted from a complex
 interplay of climatic variables and rhizosphere microbial communities. Our
 findings emphasize the importance of a spatial mid-domain effect on the
 growth of non-native E. annuus across elevation, indicating that the
 impact of E. annuus is probably greatest at mid-elevations and thus, where
 management priority should be set. Further investigations considering more
 non-native plant species and species’ traits will allow us to scrutinize
 this vision.

 data and file structure Biomass of *E. annuus* showed a hump-shaped
 pattern with elevation, while *A. lavandulifolia* biomass declined. *E.
 annuus* was mainly influenced by spatial mid-domain effects, whereas *A.
 lavandulifolia* biomass was shaped by climate and rhizosphere microbes.
