ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability.

Soil microorganisms are major regulators of ecosystem functioning and under threat from human-induced disturbances. Among these threats is grassland degradation, which estimated to affect 49% the area worldwide, threatening biodiversity functioning. Yet, we currently lack an understanding how degradation influences belowground microbial communities, their stability, functioning, effective restoration efforts for recovery important properties. Here, assessed soil fungal network complexity a suite functions along well-characterised gradient on Qinghai-Tibetan Plateau, conducted accompanying microcosm experiment designed test effects stability in communities. We found that with increasing levels communities became less complex were compositionally stable when confronted drought laboratory conditions. Moreover, this degradation-induced reduction community was associated lower multifunctionality. However, multifunctionality failed recover even after ten years restoration. Our results indicate simplification can potentially impair multifunctionality, thereby highlighting need protect restore healthy grasslands • Grassland resulted drought. Degradation-induced Fungal

Afforestation is an effective approach to rehabilitate degraded ecosystems, but often depletes deep soil moisture. Presently, it not known how afforestation-induced decrease in moisture affects microbial community and functionality, hindering our ability understand the sustainability of rehabilitated ecosystems. To address this issue, we examined impacts 20 years afforestation on bacterial community, co-occurrence pattern, functionalities along vertical profile (0-500 cm depth) a semiarid region China's Loess Plateau. We showed that effects with deep-rooted legume tree cropland were greater than top layers, resulting decreased beta diversity, more responsive taxa functional groups, increased homogeneous selection, network robustness soils (120-500 cm). Organic carbon nitrogen decomposition rates multifunctionality also significantly by afforestation, limitation soils. Moreover, changes functionality layer was largely related Such negative should be fully considered for assessing afforestation's eco-environment ecosystems because have important influence forest arid climates.

Abstract Mutualism is commonly observed in nature but not often reported for bacterial communities. Although abiotic stress thought to promote microbial mutualism, there a paucity of research this area. Here, we monitor communities quasi-natural composting system, where temperature variation (20 °C–70 °C) the main stress. Genomic analyses and culturing experiments provide evidence that selects slow-growing stress-tolerant strains (i.e., Thermobifida fusca Saccharomonospora viridis ), mutualistic interactions emerge between them remaining through sharing cobalamin. Comparison 3000 pairings reveals mutualism common (~39.1%) competition rare (~13.9%) pairs involving T. S. . Overall, our work provides insights into how high can favour reduce at both community species levels.

Abstract Microorganisms of the soil‐root continuum play key roles in ecosystem function. The Loess Plateau is well known for its severe soil erosion and thick loess worldwide, where mean annual precipitation (MAP) nutrients decrease from southeast to northwest. However, relative influence environmental factors on microbial community four microhabitats (bulk soil, rhizosphere, rhizoplane, endosphere) along gradient remains unclear. In this study, we investigated 82 field sites warm‐temperate desert grasslands across Plateau, China, assess bacterial diversity, composition, assembly, co‐occurrence networks an using 16S recombinant DNA amplicon sequencing. We discovered that explained largest source variations diversity composition region. Environmental (e.g., MAP, organic carbon, pH) impacted rhizoplane communities, but their effects decreased with increased proximity roots MAP enlarged dissimilarity communities rhizosphere bulk soil. Additionally, stochastic assembly processes drove endosphere whereas were governed primarily by variable selection deterministic processes, which showed importance grasslands. Moreover, properties indicate more stable grasslands, likely conferring resistance higher stress environments. Collectively, our results had different sensitivities mechanisms gradient. These patterns are shaped simultaneously intertwined dimensions change Plateau.

Abstract Background Increasing attention has recently been devoted to the anaerobic ammonium oxidation (anammox) in eutrophic lakes due its potential key functions nitrogen (N) removal for eutrophication control. However, successful enrichment of anammox bacteria from lake sediments is still challenging, partly ecological interactions between and denitrifying across such with remain unclear. Results This study thus designed fill knowledge gaps using bioreactors enrich more than 365 days. We continuously monitored influent effluent water, measured denitrification efficiencies, quantified bacteria, as well related N cycling genes. found that maximum efficiencies NH 4 + NO 2 − reached up 85.92% 95.34%, respectively. Accordingly, diversity decreased significantly enrichment, relative dominant (e.g., Candidatus Jettenia) Thauera, Afipia ) shifted considerably. The cooperation tended increase microbial community stability, indicating a coupling bacteria. Moreover, nirS -type denitrifiers showed stronger nirK during enrichment. Functional potentials depicted by metagenome sequencing confirmed denitrification. Metagenome-assembled genomes-based model indicated most could provide various materials amino acid, cofactors, vitamin Cross-feeding highlights importance increasing lakes. Conclusions greatly expands our understanding mechanisms among sediments, which sheds new insights into controlling eutrophication.
