Soil multitrophic network complexity enhances the link between biodiversity and multifunctionality in agricultural systems

Global Change Biology, Год журнала: 2021, Номер 28(1), С. 140 - 153

Опубликована: Окт. 7, 2021

Belowground biodiversity supports multiple ecosystem functions and services that humans rely on. However, there is a dearth of studies exploring the determinants biodiversity-ecosystem function (BEF) relationships, particularly in intensely managed agricultural ecosystems. Here, we reported significant positive relationships between soil organism groups 228 fields, relating to crop yield, nutrient provisioning, element cycling, pathogen control. The were influenced by types organisms phylotypes with larger sizes or at higher trophic levels, for example, invertebrates protist predators, appeared exhibit weaker no BEF when compared those smaller lower archaea, bacteria, fungi, phototrophs. Particularly, highlighted role network complexity, reflected co-occurrence patterns among multitrophic-level organisms, enhancing link functions. Our results represent advance forecasting impacts belowground multitrophic on systems, suggest complexity should be considered key factor productivity sustainability under land-use intensification.

Опубликована: Март 25, 2019

Revealing the ecological roles of core microbiota in community maintaining and soil nutrient cycling is crucial for understanding ecosystem function, yet there a dearth continental-scale studies on this fundamental topic microbial ecology. Here, we collected 251 samples from adjacent pairs maize rice fields at continental scale eastern China. We revealed major complex connections between bacterial taxa their associations with belowground multinutrient cycling. By identifying habitat preferences microbiota, built atlas mapping spatial distributions bacteria agro-soils, which helps forecast responses agricultural ecosystems to anthropogenic disturbance. The index soils was related α-diversity β-diversity, respectively. Rice exhibited higher diversity closer cooccurrence relationships than soils. In contrast macro- or microecological latitudinal richness patterns natural terrestrial ecosystems, showed high latitudes; however, trend not observed This study provides new perspective distinct biogeographic predict agro-soils thus manage communities better provisioning key services. IMPORTANCE Disentangling an important poorly understood presents exploratory effort gain predictive microbiota. A systematic, survey conducted using (dryland) (wetland) across results indicate that play are associated through preferences. represents significant advance forecasting disturbance services-the ultimate goal

Fungi are key players in vital ecosystem services, spanning carbon cycling, decomposition, symbiotic associations with cultivated and wild plants pathogenicity. The high importance of fungi processes contrasts the incompleteness our understanding patterns fungal biogeography environmental factors that drive those patterns. To reduce this gap knowledge, we collected validated data published on composition soil communities terrestrial environments including plant-associated habitats made them publicly accessible through a user interface at https://globalfungi.com . GlobalFungi database contains over 600 million observations sequences across > 17 000 samples geographical locations additional metadata contained 178 original studies millions unique nucleotide (sequence variants) internal transcribed spacers (ITS) 1 2 representing species genera. study represents most comprehensive atlas global distribution, it is framed such way third-party addition possible.

Trends in Microbial Community Composition and Function by Soil Depth

Microorganisms, Год журнала: 2022, Номер 10(3), С. 540 - 540

Опубликована: Фев. 28, 2022

Microbial communities play important roles in soil health, contributing to processes such as the turnover of organic matter and nutrient cycling. As edaphic properties chemical composition physical structure change from surface layers deeper ones, microbiome similarly exhibits substantial variability with depth, respect both community functional profiles. However, studies often neglect soils, instead focusing on top layer soil. Here, we provide a synthesis how its resident depth. We touch upon physicochemical properties, microbial diversity, composition, profiles, special emphasis carbon In doing so, seek highlight importance incorporating analyses soils studies.

Rare Species-Driven Diversity–Ecosystem Multifunctionality Relationships are Promoted by Stochastic Community Assembly

mBio, Год журнала: 2022, Номер 13(3)

Опубликована: Апрель 14, 2022

The relative functional importance of rare and abundant species in driving relationships between biodiversity ecosystem functions (BEF) remains unknown. Here, we investigated the roles diversity (multitrophic soil organism groups) on multifunctionality derived from 16 228 agricultural fields relating to crop health. results revealed that species, rather than was positively related multifunctionality. Abundant taxa tended maintain a larger number taxa, while subcommunity contributed more phylotypes supporting single functions. Community assembly processes were closely performance biodiversity, only observed subcommunity. Higher contributions stochastic promoted positive effects multifunctionality, reducing their overall. Our highlight for elucidate linkage ecological BEF relationships.

Afforestation can lower microbial diversity and functionality in deep soil layers in a semiarid region

Global Change Biology, Год журнала: 2022, Номер 28(20), С. 6086 - 6101

Опубликована: Июль 9, 2022

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.

Inter-bacterial mutualism promoted by public goods in a system characterized by deterministic temperature variation

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Сен. 5, 2023

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.
