“…Similar results for non‐crop plant species are however limited. In contrast to the laboratory multiplication experiments by Reis, Freitas & van der Putten (2008) and de la Peña, Bonte & Moens (2009), we could not detect species level responses of nematodes to plant genotypic identity. However, because we considered occurrence instead of abundance, and because nematodes in the field rarely reach laboratory densities, the detection level of responses in our study could have been considerably lower.…”

“…Two studies have investigated the effect of variation in the dune grass Ammophila arenaria (L.) Link on the performance of root‐feeding nematodes (Reis, Freitas & van der Putten 2008; de la Peña, Bonte & Moens 2009). In both cases, at least some of the tested nematode populations showed different multiplication on different host plant populations.…”

Summary1. Invertebrate species generally do not respond independently to genotypic variation in plants, giving rise to clusters of species that naturally associate with or avoid certain genotypes. This covariation causes coevolution to be diffuse rather than pairwise. Studies on this topic, however, have never considered the belowground invertebrate community, leaving a critical gap in our understanding. 2. We investigated the covariation among naturally colonising above-and belowground invertebrate species across six genetically distinct populations of the dune grass Ammophila arenaria. After having grown from seed in a common garden, plants were randomised in a single field site to exclude all but broad-sense genetic variation. 3. Strong positive covariation across genotypes among both above-and belowground invertebrates was detected, while correlations between these two groups were negative. This clustering of above-and belowground species matched well with order level taxonomy. Host range, trophic level and food type on the other hand did not correspond well with the clusters. Within the cluster of aboveground fauna, subsequent groupings were not related to any phylogenetic or ecological characteristic, although correlations within these subgroups were very high. We furthermore demonstrated significant differences in multiple invertebrate species occurrence between plant genotypes, in general as well as at the above-and belowground level. 4. The observed strong covariation suggests diffuse coevolution between A. arenaria and its associated invertebrate species. The trade-off between root and shoot invertebrates could however hamper directional selection on resistance to either group. 5. Our results clearly demonstrate the need for studies of plant-animal interactions to include the belowground fauna, as this might drastically alter our general conception of how plants and their associated animal communities interact and how these interactions shape the process of evolution.

“…The selection against negative plant-soil feedback could thus be stronger in the invasive range. Alternatively, there may be high variation in the intensity of plant-soil feedback in the native range (Peña et al 2009;FelkerQuinn et al 2011;Lankau 2013) and genotypes that have less negative intraspecific plant-soil feedback in the native range could also be the ones that are spreading or are spreading more successfully into the new range. This explanation is consistent with our results, as we also found differences among soil feedbacks of plants grown from different individuals within populations of R. austriaca (Table 2a).…”

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.

“…Evidence for local adaptation to soil biota was found in the case of Trifolium repens and Rhizobium bacteria [20], Amphicarpaea bracteata and Bradyrhizobium bacteria [21], Allium vineale and Uniola paniculata to arbuscular mycorrhizal fungi [22], [23]. Contrasting results have been reported for Acacia species and Rhizobium bacteria [24], Pinus and Rhizopogon fungi [25], Ammophila arenaria and nematodes [26]. Most of these studies were however limited because they did not consider the hypothesis that adaptation might be manifested at different spatial scales [27]–[29].…”

BackgroundSoil biota effects are increasingly accepted as an important driver of the abundance and distribution of plants. While biogeographical studies on alien invasive plant species have indicated coevolution with soil biota in their native distribution range, it is unknown whether adaptation to soil biota varies among populations within the native distribution range. The question of local adaptation between plants and their soil biota has important implications for conservation of biodiversity and may justify the use of seed material from local provenances in restoration campaigns.Methodology/Principal FindingsWe studied soil biota effects in ten populations of the steppe grass Stipa capillata from two distinct regions, Europe and Asia. We tested for local adaptation at two different scales, both within (ca. 10–80 km) and between (ca. 3300 km) regions, using a reciprocal inoculation experiment in the greenhouse for nine months. Generally, negative soil biota effects were consistent. However, we did not find evidence for local adaptation: both within and between regions, growth of plants in their ‘home soil’ was not significantly larger relative to that in soil from other, more distant, populations.Conclusions/SignificanceOur study suggests that negative soil biota effects can prevail in different parts of a plant species' range. Absence of local adaptation points to the possibility of similar rhizosphere biota composition across populations and regions, sufficient gene flow to prevent coevolution, selection in favor of plasticity, or functional redundancy among different soil biota. From the point of view of plant - soil biota interactions, our findings indicate that the current practice of using seeds exclusively from local provenances in ecosystem restoration campaigns may not be justified.
