Interactions between soil microbes and native species drive a diversity-invasibility relationship
<p>Soil microbes can affect both the invasiveness of exotic plants and the invasibility of native plant communities, but it still remains unclear whether soil microbes can influence the relationship between native plant species diversity and community invasibility. We constructed native plant communities with three levels of species richness (one, three, or six species) in un-sterilized or sterilized soil (i.e., with or without soil microbes) and let them not be invaded by exotic plant species or invaded by one of three exotic species (<em>Solidago canadensis</em>, <em>Erigeron canadensis</em> or <em>Symphyotrichum subulatum</em>) highly invasive in China. The soils conditioned by the native plant communities not invaded by the exotic species were used as soil microbe inocula to test whether richness-induced differences in soil microbes affect the growth of each of the three invasive species. Compared with the presence of soil microbes, the absence of soil microbes weakened the negative species richness-invasibility relationship, indicating that soil microbes can contribute to the higher invasion resistance of more diverse native plant communities. In the presence of soil microbes, the higher invasion resistance of more diverse communities was mainly ascribed to the complementarity effect. However, soil microbes from communities with a higher species richness did not have a stronger negative effect on the growth of any of the three invasive species. We conclude that soil microbes can alter the diversity-invasibility relationship through promoting the complementarity effect on the community invasion resistance. Our results highlight the importance to integrate the role of soil microbes in testing the diversity-invasibility hypothesis.</p>

Herbivory and allelopathy contribute jointly to the diversity-invasibility relationship
<p><span>To construct experimental communities of different species richness (1, 2, 4 and 8 species), we used eight native species (<em>Arctium lappa</em> L., <em>Patrinia villos</em>a (Thunb.) Juss., <em>Achyranthes bidentata</em> Bl.,<em> Reynoutria japonica </em>Houtt., <em>Taraxacum mongolicum</em> Hand.-Mazz., <em>Plantago asiatica</em> Ledeb., <em>Platycodon grandiflorus</em> (Jacq.) A. DC., <em>Antenoron filiforme</em> (Thunb.) Rob. et Vaut.). These species were chosen because they are common in natural shrub-grassland communities in the Zhejiang province, China, and two of them, <em>P. villosa</em> and <em>A. bidentata</em>, are usually very dominant in those communities. <em>Solidago canadensis</em> L. was selected as the invader.</span></p> <p><span>In May 2017, we prepared 188 plots of 2 m × 2 m in a previous agricultural field that had been abandoned seven years earlier, in Luqiao (121°23′46.16″ E, 28°31′21.62″ N). During October to December 2016, the top 10 cm of the soil was removed to deplete the seed bank, and the remaining soil was ploughed and repeatedly rotovated to produce a fine soil. In March to April 2017, the plots were weeded three times to further deplete the seed bank. The experimental area was divided into four blocks of 47 plots. In each plot, we constructed monocultures for each of the eight species with one replicate each, six two-species mixtures of different compositions and with three replicates each, six four-species mixtures with different compositions and three replicates each, and one eight-species mixture with three replicates. Each native species was used in an equal number of plots at each species-richness level. When the invasion treatment started, we also established three monoculture plots of the invader (<em>S. canadensis</em>) to assess potential side effects of activated carbon application</span></p>
Evidence for Elton's diversity-invasibility hypothesis from belowground
<p>Sixty year ago, Charles Elton posed that species-rich communities should be more resistant to biological invasion. However, still little is known about which processes could drive the diversity-invasibility relationship. Here we examined whether soil-microbes-mediated apparent competition on alien invaders is more negative when the soil originates from multiple native species. We trained soils with five individually grown native species, and used amplicon sequencing to analyze the resulting bacterial and fungal soil communities. We mixed the soils to create trained soils from one, two or four native species. We then grew four alien species separately on these differently trained soils. In the soil-conditioning phase, the five native species built species-specific bacterial and fungal communities in their rhizospheres. In the test phase, it did not matter for biomass of alien plants whether the soil had been trained by one or two native species. However, the alien species achieved 11.7% (95% CI: 3.7% ~ 20.1%) less aboveground biomass when grown on soils trained by four native species than on soils trained by two native species. Our results revealed soil-microbes-mediated apparent competition as a mechanism underlying the negative relationship between diversity and invasibility.</p>
