Summary: The presence of AMF community in canola rhizosphere and bulk soils sheds new light on AMF ecology, especially considering that canola belongs to non-mycorrhizal plants. Additionally, the sharing of bacterial cohorts between two AMF species in bulk soil provides new perspectives for research in AMF-bacteria interactions.

Summary: The type of mycorrhizal associations and the surrounding vegetation have significant effects on the distribution of rhizosphere bacterial communities. The density and size of neighbouring trees influence the diversity of bacterial communities associated with different mycorrhizal types, and the response differs between ectomycorrhizal and arbuscular mycorrhizal trees.

Summary: This study revealed significant differences in the regulation of phosphorus-promoting bacterial (PMB) communities by arbuscular mycorrhizal fungi (AMF) in the rhizosphere and hyphosphere. The PMB community in the rhizosphere was greatly affected by AMF, while in the hyphosphere, PMB were mainly shaped by roots rather than AMF.

Summary: The diversity and community composition of AMF in roots and rhizosphere soil of dominant perennial grasses were found to change in response to grazing intensity. Different virtual taxa of AMF showed varying responses along the grazing gradient, with Glomeraceae being the most abundant family. Grazing preference by sheep did not explain much of the variation in AMF diversity, but the two grass species exhibited different AMF community composition in their roots and rhizosphere soils. Overall, long-term grazing intensity may have favored disturbance-tolerant AMF taxa.

Summary: The study revealed relatively stable species composition of wheat rhizosphere microorganisms in the seedling, tillering, and flowering stages in confined isolation environments, with marked microbial changes at mature stages. The results suggest that the function of Energy metabolism gradually decreases, while the function of Transmembrane transport increases during wheat development, with the tillering stage being more complex than other stages.

Summary: This study investigated the effects of AMF on plant growth, Pb translocation, and bacteria community in rhizosphere and non-rhizosphere soils spiked with Pb. The results showed that AMF significantly increased the uptake of Pb by Paspalum notatum, and the concentration of soil exchangeable Pb was significantly reduced after plant cultivation, with further reduction observed with AMF application. The majority of the original exchangeable Pb was transformed into stabilized forms. The bacteria community exhibited differences between rhizosphere and non-rhizosphere soils, and both AMF and Pb were stronger impact factors affecting the beta-diversity of soil bacteria community than rhizosphere.

Summary: Root hairs, arbuscular mycorrhizal (AM) fungi, and rhizosphere microbiome all play important roles in plant phosphorus (P) absorption, with AM fungi having a greater impact on the rhizosphere microbial community. The microbial phosphorus mineralization process in the rhizosphere contributes more than half of plant P assimilation. The application of inorganic P reduces the effects of root hairs and AM fungi on the rhizosphere microbial community.

Summary: The research found that extraradical hyphae interact with soil microbial communities in both positive and negative ways, showing similar patterns of member enrichment but differences at lower taxonomic levels among samples from different soils. Two fungal species displayed similar compositions in the extraradical hyphae-associated community, but differed in their selection and enrichment for specific taxa. A distinct community was established within 14 days of hyphal access to the soil, with varying temporal patterns of establishment and turnover among taxonomic groups.

Summary: Our study found that the co-amendment of AMF and goethite can reduce CO2 emissions from rhizodeposits and promote their allocation into macro-aggregates, while AMF inoculation accelerates soil organic carbon turnover and rhizodeposit stabilization. These results highlight the potential of both goethite and AMF to contribute to carbon accrual in a soil-plant system.

Summary: The addition of biochar increases the colonization rate of arbuscular mycorrhizal fungi (AMF) and significantly improves maize growth and phosphorus uptake. Biochar mainly enhances phosphorus uptake by regulating root morphology and plant phosphorus content, whereas AMF enhances microbial activity and phosphatase activity, leading to more efficient phosphorus uptake by maize, especially under water stress conditions.

Summary: The changing rainfall patterns and water availability pose a significant threat to plant productions systems and food security worldwide. This study demonstrates that arbuscular mycorrhizal (AM) fungi can mitigate the negative effects of low water availability on sorghum growth and phosphorus uptake, and this effect is associated with shifts in the fungal community structure. Further research on the interactions between AM fungi and edaphic stresses in crop systems is needed to fully realize their potential in sustainable agriculture.

Summary: The increase in livestock grazing in African drylands threatens land productivity and ecosystem functioning. Few studies have looked at the impact of grazing intensity on hydrological functioning in different land uses. This study found that high grazing intensity led to increased soil bulk density, decreased infiltration capacity, and decreased soil organic carbon. However, restricting grazing can reverse these negative impacts.

Summary: This study found that different tree species have varying levels of support for beetle diversity, which is predicted by plant traits. Plant traits can explain the abundance, richness, and diversity of beetle communities. A small number of selected tree species can support higher beetle species richness compared to a random community of tree species.

Summary: This study investigated the negative impact of cheatgrass on sagebrush growth and the reasons for displacement of native plants by invasive species. The results showed that rapid soil alteration by cheatgrass led to suppression of sagebrush growth, which may contribute to the low success rate of sagebrush restoration.

Summary: Charcoal production in miombo woodlands is a major cause of forest degradation and has a significant impact on water resources. It has been found that small clearings have less effect on soil hydrological functioning and organic carbon content compared to large clearings in miombo woodlands. Controlling livestock grazing can further minimize soil degradation.

Summary: This study assesses the contribution of tree planting to ecosystem restoration in tropical and sub-tropical Asia. The mortality rate of planted trees was found to be 18% after one year, increasing to 44% after five years. Active restoration resulted in faster accumulation of tree basal area, but tree species richness did not differ compared to natural regeneration. Planting for restoration is potentially rewarding but risky and context-dependent.

Summary: Water security is a major challenge in East Africa, and improving soil infiltrability can help address this issue. This study aimed to understand the main drivers of infiltrability in different landscapes. The results showed that sand content, soil organic carbon, and functional diversity of woody vegetation were positively associated with infiltrability, while erosion and grazing pressure had a negative relationship. Therefore, land restoration strategies targeting these factors can enhance infiltrability and help alleviate water scarcity.

Summary: Despite the common assumption that trees have negative effects on local hydrological budget, this study demonstrates that trees can actually have positive effects by reducing surface run-off and improving soil infiltrability and groundwater recharge. The research also found that during wet and dry seasons, trees and grasses exhibit niche partitioning for water resources, with trees relying heavily on groundwater during the dry season. Additionally, isotopic data suggest that trees reduce evaporative water losses from the soil surface and enhance preferential flow, contributing to the positive effects on the local water balance and providing implications for landscape management.
