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.

Destabilized microbial networks with distinct performances of abundant and rare biospheres in maintaining networks under increasing salinity stress

Abstract Global changes such as seawater intrusion and freshwater resource salinization increase environmental stress imposed on the aquatic microbiome. A strong predictive understanding of responses microbiome to will help in coping with “gray rhino” events environment, thereby contributing an ecologically sustainable future. Considering that microbial ecological networks are tied stability ecosystem functioning abundant rare biospheres different biogeographic patterns important drivers functioning, roles maintaining need be clarified. Here we showed that, increasing salinity induced by freshwater‐to‐seawater transition, diversity reduced significantly taxonomic structure experienced a succession. The complexity were diminished stress. composition microorganisms supporting underwent sharp turnovers during biosphere behaving more robustly than biosphere. Notably, played much role stabilizing under low‐stress environments, but difference between their relative importance narrowed stress, suggesting weakened “Matthew effect” world. With in‐depth insights into ecology our findings highlight adjusting conservation strategies for maintain functions services response rising

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

mBio, Journal Year: 2022, Volume and Issue: 13(3)

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.

Soil microbes, the main driving force of terrestrial biogeochemical cycles, facilitate soil organic matter turnover. However, influence fauna on microbial communities remains poorly understood. We investigated microbiota dynamics by introducing competition and predation among into two ecosystems with different fertilization histories. The interactions significantly affected rare including bacteria fungi. Predation enhanced abundance C/N cycle-related genes. Rare are important drivers functional gene enrichment. Key taxa, SM1A02, Gammaproteobacteria, HSB_OF53-F07, were identified. Metabolomics analysis suggested that increased may be due to specific metabolic activity mediated interactions. had a stronger effect genes, metabolism compared competition. Long-term fertilizer application resistance animal These findings provide comprehensive understanding community under biological interactions, emphasizing roles in ecosystems.

Land management shapes drought responses of dominant soil microbial taxa across grasslands

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 2, 2024

Soil microbial communities are dominated by a relatively small number of taxa that may play outsized roles in ecosystem functioning, yet little is known about their capacities to resist and recover from climate extremes such as drought, or how environmental context mediates those responses. Here, we imposed an situ experimental drought across 30 diverse UK grassland sites with contrasting management intensities found that: (1) the majority dominant bacterial (85%) fungal (89%) exhibit resistant opportunistic strategies, possibly contributing ubiquity dominance sites; (2) intensive decreases proportion drought-sensitive non-resilient bacteria-likely via alleviation nutrient limitation pH-related stress under fertilisation liming-but has opposite impact on fungi. Our results suggest potential mechanism which promotes bacteria over fungi implications for soil functioning.
