“…Soil C (r = 0.375, P < 0.05) and N (r = 0.652, P < 0.01) were significantly correlated with reclamation period, which supports previous studies on an increase in organic matter along the successional stage (Zhao et al, 2013;Lozano et al, 2014). pH gradually approximated to neutral with soil carbon improvement, and was negatively correlated with soil C (r = −0.328, P < 0.05).…”

“…pH gradually approximated to neutral with soil carbon improvement, and was negatively correlated with soil C (r = −0.328, P < 0.05). Litter inputs, and root and microbial exudates reduced pH, and the optimal pH was beneficial for aboveground and belowground biomass accumulations (Putten et al, 2013;Lozano et al, 2014). This indicates that plant and soil mutually promote the rehabilitation process.…”

“…In a dry environment, microbial succession may lag behind plant succession, but plant and microbes demonstrate a similar succession pattern (Lozano et al, 2014). Previous studies reported that bacteria and fungi evolved along different trajectories under various conditions, such as secondary succession in a restored ecosystem (Banning et al, 2011;Li et al, 2013a), shrub encroachment (Yannarell et al, 2014), and the primary succession of lava flows (Cutler et al, 2014) and glacier soils (Brown and Jumpponen, 2014).…”

“…Previous studies have shown that soil microbial community succession is a long and non-monotonic process (López-Lozano et al, 2013;Mastrogianni et al, 2014). Lozano et al (2014) showed that microbial community succession is closely correlated with multiple ecosystem functions. However, the links between below-ground and above-ground succession processes are poorly understood.…”

Ecological restoration of mining areas has mainly focused on the succession dynamics of vegetation and the fate of microbial communities remains poorly understood. We examined changes in soil characteristics and plant and microbial communities with increasing reclamation period in an open coal mine. Bacterial, archaeal and fungal communities were assessed by tag-encoded 454 pyrosequencing. At the phylum level, Proteobacteria, Crenarchaeota, and Ascomycota had the highest detected relative abundance within bacteria, archaea, and fungi, respectively. Partial regressions and canonical correspondence analysis demonstrated that vegetation played a major role in bacterial and archaeal diversity and assemblies, and soil characteristics, especially nitrogen, were important for fungal diversity and assemblies. Spearman rank correlation indicated that bacterial and archaeal communities showed synergistic succession with plants; whereas, fungal communities showed no such pattern. Overall, our data suggest that there are different drivers of bacterial, archaeal and fungal succession during secondary succession in a reclaimed open mine.

Influence of soil microbiota in nurse plant systems

Summary Facilitation by nurse plants is a key process involved in the organization of plant communities and maintenance of biodiversity, particularly in harsh environments. Nurse plants increase plant diversity and productivity in these ecosystems, but our knowledge on the mechanisms through which such facilitation operates is still expanding. Despite growing evidence that soil microbiota impact plant fitness and community dynamics, their role in plant facilitation has been little explored. Here, we synthesize available evidence on the effect of nurse plants on the abundance, composition and activity of soil microbial communities, and the effect of these soil communities on beneficiary plant species. Studies conducted mostly in arid and semi‐arid systems show that nurse plants promote the development of differentiated soil microbial communities characterized by a higher microbial abundance and activity, the dominance of competitive bacteria and larger mycorrhizal networks, compared to gaps and to coexisting non‐nurses. There is also evidence that differentiated soil microbiota associated with nurse plants has positive effects on the establishment, growth and fitness of beneficiary plant species, although the mechanisms involved remain unclear. We suggest that they include increased nutrient availability for plants, a better use of resources through functional complementarity in the microbial community, soil stabilization and also direct molecular signalling between soil microbes and plants that affect plant defence and plant interactions. Evidence for the role of soil microbiota as mediators of facilitation by nurse plants is growing, but there are still too few studies on which to draw generalizable conclusions. Future studies are needed to assess the effect of plant ontogeny and environmental conditions on soil microbial communities under nurse plants and other coexisting species, and to determine the microbial groups and specific mechanisms involved in facilitation by nurse plants.

Changes in plants and soils during natural succession have been evaluated, but little is known about the effects of succession on the activities of soil microbes and their interactions with soil erodibility. We conducted a field study on the Chinese Loess Plateau, typical of this semiarid area, to determine the effect of secondary succession on the stability of soil structure against erosion and on the composition of soil fungal communities. Characteristics of plant, soil, and fungal communities were assessed across a 30-yr chronosequence of grassland developed from abandoned cropland. The diversity and composition of the fungal communities were determined using high-throughput sequencing of the internal transcribed spacer. Six grasslands were selected to represent different successional age classes: 0 (cropland), 5, 10, 15, 20, and 30 yr. Short-term decreases (initial 5 yr) in the amounts of soil organic carbon, total nitrogen, available phosphorus, and fungal biomass and in fungal diversity had returned to original levels (i.e., cropland) within 15 yr and were much higher after continued succession. Abandoning cropland for succession caused the soil erodibility (K) decrease and the aboveground coverage, soil nutrient levels, content of larger (>5 mm) water-stable aggregate, mean aggregate weight diameter, and diversity of the fungal communities improvement including arbuscular mycorrhizas (AMF), ectomycorrhizas (EMF), and saprotrophs. The fungal communities were dominated by Ascomycota, Zygomycota, Basidiomycota, and Glomeromycota during the succession. The successional patterns of the plant and fungal communities were similar, although distinct fungal communities were not observed in the two initial stages, suggesting that fungal succession may develop more slowly than plant succession. Plant root biomass, EMF, and soil organic carbon content accounted for most of the variation of soil erodibility (28.6%, 19.5%, and 11.8%, respectively), indicating their importance in shaping soil structure to prevent erosion. Our results demonstrated that abandoning cropland for natural succession could decrease soil erodibility and increase fungal diversity. EMF plays an important role in soil stability against erosion in the Loess Plateau. Abandoning cropland for natural succession should be recommended for alleviating soil erosion and improving the degraded soils in this area.
