title: Data from: Soil fungal influence on the diversity-invasibility relationship depends on interacting species identities

description: Elton’s diversity-invasibility hypothesis, which proposes that diverse
 communities should be more resistant to biological invasions, has been the
 focus of much attention. However, little is known about how soil microbes
 recruited by native plants influence the vulnerability of forest
 ecosystems to invasion by exotic plants. Here, we present a two-part
 plant–soil feedback experiment (Part A, diversity effect; Part B, soil
 inoculation) to examine the effects of soil microorganisms associated with
 native plant species at different diversity levels on community
 invasibility of temperate forests, using two invasive plants, Rhus typhina
 and Phytolacca americana, as test species. Aboveground plant growth and
 biomass allocation differed significantly between the two invasive plants
 under simulated diversity, with negative effects on P. americana and
 positive effects on R. typhina. Both the diversity effects and soil
 inoculation experiments showed that the growth of P. americana was
 inhibited, while that of R. typhina was promoted by soil microorganisms.
 In contrast to the non-mycorrhizal P. americana, the arbuscular
 mycorrhizal plant R. typhina enhanced its stress tolerance through close
 associations with soil fungi. Our study suggests that the role of soil
 microbes in the ‘diversity-invasibility’ relationship might be related to
 the species identities (e.g., mycorrhizal type) of both invasive and
 native species. These results shed new light on Elton’s
 diversity-invasibility hypothesis by highlighting the role of plant-soil
 feedback mechanisms.
description: We utilized a linear mixed model, implemented using the ‘lme4’
 package (Bates et al., 2015) in R 4.0.5 (R Core Team, 2021), to analyze
 the effects of diversity on the growth of two invasive plant
 species.
