“…This indicates that all the species except C. arvense experience some type of positive intraspecific feedback or there is not effect. Such a result in fact contrasts with conclusions of many previous studies indicating that intraspecific plant-soil feedbacks are mostly negative (Bever 2003, Kulmatiski et al 2008, Petermann et al 2008, Zuppinger-Dingley et al 2011, van der Putten et al 2013. Positive intraspecific feedbacks are known mostly from studies dealing with invasive species (e.g., Klironomos 2002).…”

Plant‐soil feedback (PSF) represents an important process affecting natural plant communities. While many previous studies demonstrated the variation in the intensity of PSF between species, the mechanisms driving these differences are still largely unexplored. The aim of the study was to explore the importance of species traits and species phylogenetic relationships on the intensity of plant‐soil feedback. To do this we used a classical design to test plant soil feedback, i.e., a two‐phase experiment consisting of conditioning and cultivation phase. In the conditioning phase, we used 30 different species from the Carduoidea subfamily of Asteraceae and conditioned soil by each of these species separately. In the cultivation phase, we observed growth of four of these species in all the soils. We predict that the intensity of PSF will be more intense between plants which are more closely related than between unrelated species. As an alternative, we explore the possibility that the intensity of PFS will be a function of plant traits related to nutrient acquisition by the plant. The intensity of feedback was significantly dependent on phylogeny in several cases indicating that more closely related species show more similar feedback effects. The feedback response was also affected by the chemical composition of the cultivated soil. In addition, the intensity of feedback was affected by height of the cultivating species and its ability to accumulate nitrogen and phosphorus in their leaves. While in most of these cases there is an indication that plants grow better in soils cultivated by smaller species accumulating less nutrients, in some cases the pattern in opposite. The direction and intensity of plant‐soil feedback also strongly differed between life stages with seedling number commonly showing a response which was opposite to the response of the adults. Synthesis: The results supported our expectation that plant‐soil feedback may be affected by species phylogenetic relationships. In addition, we have shown that also plant traits and the effect of the conditioning plant on soil chemistry may be useful factors allowing us to predict the intensity of plant‐soil feedback in the system.

“…bolstered by broad comparative studies showing that invasives support fewer pathogens than do natives (Mitchell and Power 2003;Mitchell et al 2010), as well as indications that some invasives suffer from strong negative soil feedbacks where they are native (Reinhart et al 2003;Zuppinger-Dingle et al 2011;Yang et al 2013;Maron et al 2014). It is further supported by research suggesting that invasives gain a competitive edge over natives as a result of this inequality in the strength of soil feedbacks (Reinhart and Callaway 2006;Petermann et al 2008).…”

Do exotic plants lose resistance to pathogenic soil biota from their native range? A test with Solidago gigantea

Native plants commonly suffer from strong negative plant-soil feedbacks. However, in their non-native ranges species often escape from these negative feedbacks, which indicates that these feedbacks are generated by at least partially specialized soil biota. If so, introduced plants might evolve the loss of resistance to pathogens in their former native range, as has been proposed for the loss of resistance to specialized herbivores. We compared the magnitude of plant-soil feedbacks experienced by native and exotic genotypes of the perennial forb, Solidago gigantea. Feedbacks were assessed in soil collected across 14 sites sampled across the western part of Solidago's native range in the US. Both native and exotic genotypes of Solidago suffered consistently negative and broadly similar plant-soil feedbacks when grown in North American soil. Although there was substantial variation among soils from different sites in the strength of feedbacks generated, the magnitude of feedbacks generated by North American genotypes of S. gigantea were strongly correlated with those produced in the same soil by European genotypes. Our results indicate that Solidago experiences strong negative soil feedbacks in native soil and that introduced genotypes of Solidago have not lost resistance to these negative effects of soil biota. Both genotypic and landscape-level effects can be important sources of variation in the strength of plant-soil feedbacks.

“…A factor that strongly affects species success in a new range is the ability of the plant to modify the soil in which it grows and to suppress the growth of the other plants and/or support its own growth Reinhart and Callaway 2004;Zuppinger-Dingley et al 2011). This effect can be mediated through the input of chemical compounds and organic matter from the plant to the soil, by impacting hydrological processes and surface soil temperatures and by providing habitats and/or resources for soil biota (Bardgett and Wardle 2010;Lamb et al 2011).…”

Plant–soil feedback in native vs. invasive populations of a range expanding plant

et al. 2015

Background and aims Although plant-soil feedback has been suggested as a mechanism that drives the success of invasive plants, studies that investigate differences in the intensity of plant-soil feedback among native and invasive populations of the same species are still lacking. However, such knowledge is important because it can provide an understanding of the mechanisms responsible for the spread of a species. Rorippa austriaca is a potentially invasive species -a successful range expander in Europe.Methods We compared the plant-soil feedback of R. austriaca in populations from its native and invasive range. We explored both intraspecific feedback as well as feedback on a co-occurring grass species. Results Our results revealed a strong negative feedback effect as a consequence of soil conditioning by R. austriaca from the native range. On the contrary, a negative feedback effect was not observed for invasive R. austriaca. Interestingly, R. austriaca from the invasive range had a higher biomass than native R. austriaca. Conclusion Our results might be explained by pathogen accumulation and soil modification by native R. austriaca, which had strong intra-and interspecific effects that seemed to be lost in the invasive R. austriaca. The loss of negative intraspecific plantsoil feedback and the increased growth of the invasive population may contribute to its successful range expansion. In spite of its increased growth, the co-occurring grass species is expected to successfully coexist with the invasive R. austriaca.
