“…Biotic plant-soil feedback effects are known to influence plant performance and competitive ability (Van der Putten et al 1993, Bever 1994, Van der Putten and Peters 1997. Our results show that plant-soil feedback dynamics in pioneer stages of secondary succession result in a historical contingency effect that can enhance the rate of succession to later-successional Notes: Inoculum species was included as a fixed factor in the model, and plant species and plant species 3 inoculum species were random factors.…”

“…Theoretical studies show that negative plant-soil feedback can contribute to the coexistence of competitive plant species that compete for the same soil and light resources , Bever 2003. Empirical studies emphasize the potential role of plant-specific accumulation of soil-borne pathogens and negative feedbacks in species replacements (Van der Putten et al 1993, Van der Putten andPeters 1997).…”

Abstract. Plant-soil feedback affects performance and competitive ability of individual plants. However, the importance of plant-soil feedback in historical contingency processes and plant community dynamics is largely unknown. In microcosms, we tested how six earlysuccessional plant species of secondary succession on ex-arable land induced plant-specific changes in soil community composition. Following one growth cycle of conditioning the soil community, soil feedback effects were assessed as plant performance in soil of their own as compared to soil from a mixture of the other five early-successional species. Performance was tested in monocultures and in mixed communities with heterospecific competition from midsuccessional species. The role of soil microorganisms was determined by isolating the microbial component from the soil community, re-inoculating microorganisms into sterilized substrate, and analyzing plant biomass responses of the early-and mid-successional species.Plant-soil feedback responses of the early-successional species were negative and significantly increased when the plants were grown in a competitive environment with heterospecifics. In monocultures, three early-successional species experienced negative feedback in soil with a history of conspecifics, while all early-successional species experienced negative feedback when grown with interspecific competition. Interestingly, the nonnative forb Conyza canadensis showed the weakest soil feedback effect. Biomass production of the earlysuccessional plant species was profoundly reduced by the microbial inocula, most strongly when exposed to inocula of conspecific origin. Molecular characterization of the fungal and bacterial rhizosphere communities revealed a relationship between plant biomass production and the composition of the dominant fungal species. Furthermore, our results show that, in early secondary succession, the early-successional plant species induce changes in the soil microbial community composition that cause historical contingency effects in dominance patterns of mid-succession plant communities.We conclude that feedback between early-successional plant species and soil microorganisms can play a crucial role in breaking dominance of early-successional plant communities. Moreover the influences on soil microorganism community composition influenced plant community dynamics in the mid-successional plant communities. These results shed new light on how feedback effects between plants and soil organisms in one successional stage result in a biotic legacy effect, which influences plant community processes in subsequent successional stages.

“…Given our results, one might also assume that the effects of soil biota on native plants might be very site dependent, which might also help explain variation in invader abundance across introduced sites. Ultimately, asymmetry in the strength of interactions between soil biota and native versus invasive plants is very likely to give invaders a leg up in competition with natives, which could facilitate their competitive dominance (sensu Van der Putten & Peters 1997). There have been surprisingly few studies, however, comparing the strength of competition between invasives and surrounding vegetation in their home and introduced ranges.…”

Invasive plants escape from suppressive soil biota at regional scales

et al. 2013

Summary 1.A prominent hypothesis for plant invasions is escape from the inhibitory effects of soil biota. Although the strength of these inhibitory effects, measured as soil feedbacks, has been assessed between natives and exotics in non-native ranges, few studies have compared the strength of plantsoil feedbacks for exotic species in soils from non-native versus native ranges. 2. We examined whether 6 perennial European forb species that are widespread invaders in North American grasslands (Centaurea stoebe, Euphorbia esula, Hypericum perforatum, Linaria vulgaris, Potentilla recta and Leucanthemum vulgare) experienced different suppressive effects of soil biota collected from 21 sites across both ranges. 3. Four of the six species tested exhibited substantially reduced shoot biomass in 'live' versus sterile soil from Europe. In contrast, North American soils produced no significant feedbacks on any of the invasive species tested indicating a broad scale escape from the inhibitory effects of soil biota. 4. Negative feedbacks generated by European soil varied idiosyncratically among sites and species. Since this variation did not correspond with the presence of the target species at field sites, it suggests that negative feedbacks can be generated from soil biota that are widely distributed in native ranges in the absence of density-dependent effects. 5. Synthesis. Our results show that for some invasives, native soils have strong suppressive potential, whereas this is not the case in soils from across the introduced range. Differences in regional-scale evolutionary history among plants and soil biota could ultimately help explain why some exotics are able to occur at higher abundance in the introduced versus native range.
