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.

Soil microbial communities are fundamental to maintaining key soil processes associated with litter decomposition, nutrient cycling, and plant productivity thus integral human well-being. Recent technological advances have exponentially increased our knowledge concerning the global ecological distributions of across space time provided evidence for their contribution ecosystem functions. However, major gaps in biogeography remain be addressed over coming years as technology research questions continue evolve. In this minireview, we state recent future directions study discuss need a clearer concept species, projections toward change scenarios, importance embracing culture isolation approaches determine functional profiles.

Environmental adaptation is stronger for abundant rather than rare microorganisms in wetland soils from the Qinghai‐Tibet Plateau

Molecular Ecology, Journal Year: 2021, Volume and Issue: 30(10), P. 2390 - 2403

Disentangling the biogeographic patterns of rare and abundant microbes is essential in order to understand generation maintenance microbial diversity with respect functions they provide. However, little known about ecological assembly processes environmental adaptation across large spatial-scale wetlands. Using Illumina sequencing multiple statistical analyses, we characterized taxonomic phylogenetic bacteria fungi Qinghai-Tibet Plateau wetland soils. Abundant taxa exhibited broader thresholds stronger signals for traits than ones. By contrast, showed higher sensitivity changes closer clustering The null model analysis revealed that dispersal limitation belonging stochastic process dominated community assemblies bacteria, fungi, while variable selection deterministic governed bacteria. Neutral variation partitioning further confirmed were less environmentally constrained. Soil ammonia nitrogen was crucial factor mediating balance between stochasticity determinism both microbes. may have better potential are dispersed by Our findings extend knowledge ongoing change could facilitate prediction biodiversity loss caused probably climate human activity

Coexistence patterns of soil methanogens are closely tied to methane generation and community assembly in rice paddies

Microbiome, Journal Year: 2021, Volume and Issue: 9(1)

Published: Jan. 22, 2021

Soil methanogens participate in complex interactions, which determine the community structures and functions. Studies continue to seek coexistence patterns of soil methanogens, influencing factors contribution methane (CH4) production, are regulated primarily by species functional significance these interactions. Here, emissions were measured rice paddies across Asian continent, interactions involved methanogenic archaeal communities represented as pairwise links co-occurrence networks.The network topological properties, positively correlated with mean annual temperature, most important predictor CH4 among all biotic abiotic factors. The groups commonly co-occurring 39 local networks contributed emission (53.3%), much higher than endemic (36.8%). potential keystone taxa, belonging Methanobacterium, Methanocella, Methanothrix, Methanosarcina, possessed high linkages generation genes mcrA, fwdB, mtbA, mtbC. Moreover, coexisting taxa showed a very different assembly pattern, ~ 30% determinism 70% stochasticity. In contrast, proportion stochasticity (93~99%) characterized endemically taxa.These results suggest that microbes closely tied their significance, importance common further imply may contribute more diversity Video abstract.

Core phylotypes enhance the resistance of soil microbiome to environmental changes to maintain multifunctionality in agricultural ecosystems

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(22), P. 6653 - 6664

Published: Aug. 13, 2022

Agricultural ecosystems are facing increasing environmental changes. Revealing ecological stability of belowground organisms is key to developing management strategies that maintain agricultural ecosystem services in a changing world. Here, we collected soils from adjacent pairs maize and rice fields along large spatial scale across Eastern Southeast China investigate the importance core microbiota as predictor resistance soil microbiome (e.g. bacteria, fungi protist) climate changes nutrient fertilization, their effect on multiple functions, representing for crop growth health agro-ecosystems. Soil exhibited stronger than soils, by considering aspects index, example, community, phylogenetic conservation network complexity. Community showed geographic pattern, with higher at lower latitudes, suggesting warmer regions. Particularly, highlighted role phylotypes enhancing community microbiome, which was essential maintenance multifunctionality ecosystems. Our results represent significant advance linking therefore forecasting agro-ecosystems dynamics response ongoing These suggest should be considered factor sustainability productivity under global change scenarios.

Global Ecology and Biogeography, Journal Year: 2021, Volume and Issue: 30(7), P. 1488 - 1501

Published: May 19, 2021

Abstract Aim A predictive understanding of the mechanisms underlying microbial biogeographical patterns is great interest, particularly with respect to phylogenetic distributions their ecological adaptations. Here, we test whether information can predict distributions, community assembly and species co‐occurrence soil archaea. Location Northern China. Time period July August 2017. Major taxa studied Archaeal communities. Methods By conducting a large‐scale (transect intervals 1,257.6 km) study across agricultural field, forest, wetland, grassland desert biomes, applied framework niche conservatism investigate archaeal biogeography, network topology. We examined signal based on Blomberg's K environmental preference given taxon was related phylogeny, corresponding degree for niches complex gradients. evaluated processes communities null model Sloan neutral analyses. then explored major factors that influenced coexistence Results Soil exhibited strong climate‐related preferences. Mean annual precipitation (MAP) had strongest signal, this mediated both coexistence, stronger deterministic less in environments lower precipitation. Phylogenetic diversity closely linked balance processes; is, stochastic were dominant low‐diversity communities, whereas variable selection promoted high diversity. Main conclusions conclude archaea drives distributions. Our findings represent considerable advance linking therefore forecasting evolutionary adaptations response ongoing changes.
