“…PSF effects may also be stronger in long-term field experiments or with different species assemblages (Petermann et al 2008, Turnbull et al 2010, Hawkes et al 2013, Mack and Bever 2014, Maron et al 2014. Further, the magnitude of PSF effects in this study were similar or smaller than PSF effects reported across the literature suggesting that PSFs in other communities will have similar or larger effects on community composition .…”

“…This is the only study we are aware of that has performed a factorial PSF experiment with more than five species and results suggest that, relative to the nonfactorial design, the factorial design detects more than twice as many instances where PSF effects are greater than differences in intrinsic growth rates (Casper and Castelli 2007, Lankau et al 2011, Hawkes et al 2013. This is important because it determines when PSF effects are large enough to overcome differences in intrinsic growth rates between species.…”

It has become clear that plants can create soils that affect subsequent plant growth. However, because plant-soil feedbacks (PSFs) are typically measured in monoculture experiments, it remains unclear to what extent PSFs affect plant growth in communities. Here we used data from a factorial PSF experiment to predict the biomass of 12 species grown in 162 plant community combinations. Five different plant growth models were parameterized with either monoculture biomass data (Null) or with PSF data (PSF) and model predictions were compared to plant growth observed in communities. For each of the five models, PSF model predictions were closer to observed species biomass in communities than Null model predictions. PSFs, which were associated with a 28% difference in plant biomass across soil types, explained 10% more variance than Null models. Results provided strong support for a small role for PSFs in predicting plant growth in communities and suggest several reasons that PSFs, as traditionally measured in monoculture experiments, may overestimate PSF effects in communities. First, monoculture data used in Null models inherently includes "self " PSF effects. Second, PSFs must be large relative to differences in intrinsic growth rates among species to change competitive outcomes. Third, PSFs must vary among species to change species relative abundances.

“…Another important consideration is that plant responses to soil biota are not uniform over the life of plants. Past research has shown that feedback responses of native grasses tend to become more negative over time as deleterious soil microbes accumulate, while this may not be true for non-native congeners (Hawkes et al, 2012). While our results suggest positive effects of soil biota on both a native and a nonnative grass, our experiment was conducted over a 2-month period and the response of Bouteloua to soil microbes may have become negative over a longer time period.…”

“…Soil from all pots within the three variants was mixed to create specific soil types (see Hawkes et al 2013 andSun et al 2014 for similar approach). We mixed the soils because we wanted to study the overall effects of native and invasive populations of R. austriaca, rather than looking at the effect of individual genotypes or populations, and we wanted to keep the number of replicates reasonable.…”

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

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.
