Abstract Soil communities are intricately linked to ecosystem functioning, and a predictive understanding of how assemble in response environmental change is great ecological importance. Little known about the assembly processes governing abundant rare fungal across agro‐ecosystems, particularly with regard their adaptation. By considering taxa, we tested thresholds phylogenetic signals for preferences complex gradients reflect adaptation, explored factors influencing based on large‐scale soil survey agricultural fields eastern China. We found that taxa exhibited remarkably broader stronger compared taxa. Neutral played key role shaping subcommunity subcommunity. Null model analysis revealed was less clustered phylogenetically governed primarily by dispersal limitation, while homogeneous selection major process available sulfur factor mediating balance between stochastic deterministic both subcommunities, as indicated an increase stochasticity higher concentration. Based macroecological spatial scale datasets, our study potential adaptation identified distinct community fields. These results contribute mechanisms underlying generation maintenance diversity global change.

Soil pH and temperature regulate assembly processes of abundant and rare bacterial communities in agricultural ecosystems

Environmental Microbiology, Journal Year: 2019, Volume and Issue: 22(3), P. 1052 - 1065

Published: Oct. 10, 2019

Summary The factors determining stochastic and deterministic processes that drive microbial community structure, specifically the balance of abundant rare bacterial taxa, remain underexplored. Here we examined biogeographic patterns taxa explored environmental influencing their assembly in agricultural fields across eastern China. More phylogenetic turnover correlating with spatial distance was observed than sub‐communities. Homogeneous selection main process for both sub‐communities; however, sub‐community more tightly clustered phylogenetically sensitive to dispersal limitations sub‐community. Rare rice maize were governed by processes, which showed higher operational taxonomic unit richness. We propose a conceptual paradigm wherein soil pH mean annual temperature mediate sub‐communities respectively. A leads For sub‐community, dominance stochasticity low‐temperature regions indicates weaker niche‐based exclusion arrival evolutionary lineages. These findings suggest are dependent on distinct variables agro‐ecosystems.

The microbiome of pest insects: it is not just bacteria

Entomologia Experimentalis et Applicata, Journal Year: 2019, Volume and Issue: 167(3), P. 156 - 170

Published: Feb. 27, 2019

Abstract Insects are associated with multiple microbes that have been reported to influence various aspects of their biology. Most studies in insects, including pest species, focus on the bacterial communities microbiome even though consists members many more kingdoms, which can also large life history insects. In this review, we present some key examples how different microbiome, such as bacteria, fungi, viruses, archaea, and protozoa, affect fitness behavior Moreover, argue interactions within among microbial groups abundant great importance, necessitating use a community approach study microbial–host interactions. We propose restricted bacteria very likely hampers our understanding functioning impact biology close review by highlighting few open questions provide an in‐depth other components addition might host performance, thus contributing insect ecology.

Microbial assembly, interaction, functioning, activity and diversification: a review derived from community compositional data

Marine Life Science & Technology, Journal Year: 2019, Volume and Issue: 1(1), P. 112 - 128

Published: Sept. 30, 2019

Abstract Microorganisms play crucial roles in maintaining ecosystem stability. The last two decades have witnessed an upsurge studies on marine microbial community composition using high-throughput sequencing methods. Extensive mining of the compositional data has provided exciting new insights into ecology from a number perspectives. Both deterministic and stochastic processes contribute to assembly but their relative importance structuring subcommunities, that are categorized by traits such as abundance, functional type activity, differs. Through correlation-based network analysis, significant progress been made unraveling co-occurrence patterns dynamics response environmental changes. Prediction functioning, based data, is receiving increasing attention, closely related microbes often share similar ecological diversity exhibits correlations functioning. functioning likely executed not whole community, rather active fraction which can be inferred marker gene transcription level members. Furthermore, huge amount significantly expanded tree life illuminated phylogenetic divergence evolutionary history. This review summarizes important findings assembly, interaction, activity diversification, highlighting interacting different aspects, derived data.

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

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

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.
