“…First, plant genotypes are known to influence microbial communities [18,19]. Second, plantsoil feedbacks can contribute to plant-plant competitive interactions and coexistence [41][42][43], and recent studies suggest that plant-soil feedbacks can contribute to fitness differences among plant genotypes within a species [18,44]. Finally, eco-evo dynamics are expected to occur when organisms have large effects on their environment and as a result can alter the selective environment for themselves and other species in the community (i.e.…”

The relative importance of rapid evolution for plant-microbe interactions depends on ecological context

Evolution can occur on ecological time-scales, affecting community and ecosystem processes. However, the importance of evolutionary change relative to ecological processes remains largely unknown. Here, we analyse data from a long-term experiment in which we allowed plant populations to evolve for three generations in dry or wet soils and used a reciprocal transplant to compare the ecological effect of drought and the effect of plant evolutionary responses to drought on soil microbial communities and nutrient availability. Plants that evolved under drought tended to support higher bacterial and fungal richness, and increased fungal : bacterial ratios in the soil. Overall, the magnitudes of ecological and evolutionary effects on microbial communities were similar; however, the strength and direction of these effects depended on the context in which they were measured. For example, plants that evolved in dry environments increased bacterial abundance in dry contemporary environments, but decreased bacterial abundance in wet contemporary environments. Our results suggest that interactions between recent evolutionary history and ecological context affect both the direction and magnitude of plant effects on soil microbes. Consequently, an eco-evolutionary perspective is required to fully understand plant-microbe interactions.

“…Bezemer et al (2006) had proposed that plant-soil feedback depends upon the plant functional group. Differences in plant functional groups can create different soil biotic and abiotic microhabitats by affecting soil organic matter, soil nutrient availability, and soil microbial communities (Casper and Castelli, 2007). Study found that GG species proportion were significant positively related to higher soil nutrient conditions .…”

Grazing intensity is one of the most important factors influencing soil properties variations in rangeland ecosystem. This research aimed to study the features of soil properties under different grazing intensity in a Kobresia parva-meadow on the Qinghai-Tibetan Plateau, China. Results showed that soil organic matter (SOM), soil organic carbon (SOC), and total nitrogen (N) significantly decreased with an increase grazing intensity and total and available potassium (K), and C/N ratio exhibited a similar pattern. However, there were not significant differences between warm-season pasture (WSP) and cool-season pasture (CSP). In addition, results indicated that soil P was a limited factor, and N was sensitive to grazing intensity in Kobresia parva alpine meadow grazing ecosystem. Therefore, our study demonstrated that soil properties, such as soil carbon and nitrogen, generally decreased with the increasing of grazing intensity in studied Kobresia parva-meadow on the Qinghai-Tibetan Plateau.

“…Studies performed in grasslands have shown that increased soil biodiversity can enhance above-ground diversity (De Deyn et al 2004;Hooper et al 2005;Wardle et al 2004) and productivity (van der Heijden et al 1998). However, large variation exists in responses of plants to soil communities, as has been highlighted in studies on the lasting effect after cessation of agricultural management on revegetation (Kulmatiski and Beard 2008;Kulmatiski et al 2006) and in studies on plant-soil feedback (Casper and Castelli 2007). For instance, outcome and effect-size of plant-soil biotic interactions have been reported to vary from positive to negative with successional stage, soil nutrient levels, and plant species identity (Gustafson and Casper 2004;Kardol et al 2006Kardol et al , 2007.…”

Several studies have shown that soil biotic communities from organically managed fields are more diverse and exhibit higher activity levels compared to conventionally managed fields. The impact of these different soil communities on plant productivity and the provision of soil ecosystem services are, however, still unclear. Here, we test the effects of soil inoculation from each of three organic and three conventional maize fields on maize productivity and nutrient loss during leaching events induced by simulated rain. In particular, we examine whether differences in productivity and nutrient loss are related to the abundance and species composition of arbuscular mycorrhizal (AM) fungi. We hypothesized that soil biota from organically managed fields would improve maize growth and reduce nutrient leaching significantly more than those from conventionally managed fields. In contrast to our hypothesis, we found that plant productivity was negatively affected by soil inoculation, and this Plant Soil (2012) effect was stronger with inoculum from organic fields. Plant productivity was inversely correlated with AMF abundance, suggesting that enhanced carbon allocation to AMF is at least in part responsible for plant growth reduction under our experimental conditions. However, soil inoculation did alter the ecological functioning of the system by reducing phosphorus leaching losses after simulated rain. Moreover, these leaching losses were lower with increased hyphal density and were related with abundance of particular AMF types, suggesting that abundance of AMF and their community composition may be useful indicators of phosphorus leaching losses. The results demonstrate that soil communities from different agricultural fields vary in their impact on plant productivity and nutrient leaching losses. The results further indicate that there is a potential tradeoff between positive effects of soil communities on sustainability and negative effects on crop productivity.
