However, it is  unclear whether this diversity\u2013invasion relationship holds true under  environmental changes. Here, we conduct a meta-analysis of 1010  observations from 25 grassland studies in which plant species richness  is manipulated together with one or more environmental change factors to  test invasibility (measured by biomass or cover of invaders). We find  that biodiversity increases resistance to invaders across various  environmental conditions. However, the positive biodiversity effect on  invasion resistance is strengthened under experimental warming, whereas  it is weakened under experimentally imposed drought. When multiple  factors are imposed simultaneously, the positive biodiversity effect is  strengthened. Overall, we show that biodiversity helps grassland  communities resist plant invasions under multiple environmental changes.  Therefore, investment in the protection and restoration of native  biodiversity is not only important for prevention of invasions under  current conditions but also under continued global environmental change. <\/p>\n\n\n\n<figure class=\"wp-block-image size-large justify\"><img loading=\"lazy\" width=\"652\" height=\"694\" src=\"\/wp-content\/uploads\/image-260.png\" alt=\"\" class=\"wp-image-5147\" srcset=\"\/wp-content\/uploads\/image-260.png 652w, \/wp-content\/uploads\/image-260-282x300.png 282w\" sizes=\"(max-width: 652px) 100vw, 652px\" \/><figcaption> <strong>Fig. 1: Biodiversity effects on invasion resistance under multiple environmental changes.<\/strong>  The net biodiversity effect (NBE) on invasion resistance (<strong>a<\/strong>) and the difference in NBE between ambient and manipulated environmental conditions (\u2206NBE) (<strong>b<\/strong>).  Positive values of NBE indicate higher invasion resistance of resident  mixtures in comparison with that of resident monocultures, whereas  negative values indicate the opposite. Positive values of \u2206NBE indicate  stronger biodiversity effects under manipulated environmental conditions  in comparison with ambient conditions, and vice versa.

The numbers in brackets show the number of effect  sizes. Points with error bars are the estimated means with corrected 95%  confidence intervals. Confidence intervals not overlapping with the  dashed line (i.e. 0) indicate statistical significance, as indicated by  asterisks. Green shading indicates the analysis on all environmental  change factors and yellow shading indicates the analysis on different  numbers of factors.
