Residues of herbicides with the extensive applications may impact soil ecosystem and ultimately threaten agricultural sustainability. However, effects long-term herbicide residues on multifunctionality microbial community remain poorly understood. Here, we evaluated relationships between communities residual concentrations by surveying analyzing 62 black samples collected from an area in northeastern China. Total varied 35 to 568 μg/kg samples. The response increasing exhibited inverted U-shaped relationship a peak at approximately 310 μg/kg, net mineralized organic nitrogen (Nm) total (TN) exhibiting same trend. Microbial richness was significantly lower high (> HG) compared low (< LG). In addition, relative abundances specific keystone genera differed LG HG: norank_f_Acetobacteraceae, norank_f_Caldilineaceae, Candidatus_Alysiosphaera, Gonytrichum. these were also correlated multifunctionality. Structural equation models (SEMs) further showed that influenced affecting genera. Our study demonstrates soil, where stimulate while inhibit, underscoring need for reasonable application maintain health.

The present study was aimed at assessing the impact of azoxystrobin-a fungicide commonly used in plant protection against pathogens (Amistar 250 SC)-on soil microbiota and enzymes, as well growth development. laboratory experiment conducted three analytical terms (30, 60, 90 days) on sandy clay (pH-7.0). Azoxystrobin applied to doses 0.00 (C), 0.110 (F) 32.92 (P) mg kg

ABSTRACT Multifunctional redundancy, which measures the extent of loss in multiple ecosystem functions with decreasing biodiversity, stands as a crucial index for evaluating resilience to environmental changes. Previous studies have assessed functional redundancy by overlap traits or among taxonomic units, but quantifying these experimentally each unit is challenging and resource‐intensive, especially microorganisms. In this study, we aimed refine estimation multifunctional prokaryotic communities using marker‐gene‐based methodology. We used bioinformatic tool, PICRUSt2, predict KEGG ortholog (KO) composition Amplicon Sequence Variant (ASV) 16S rRNA gene community‐wide KO richness metric genomic multifunctionality. Additionally, introduced refined regression on vs. ASV curves, providing reliable estimate power‐law exponent within computational time constraints, serving index. To quantify variations between different species extinction scenarios, incorporated various non‐random scenarios alongside random one. Finally, elucidate potential mechanisms contributing applied our methodology prokaryote community Lake Biwa four its inlet rivers. Our was effectively validated quantified phenotypic application catchment revealed spatio‐temporal redundancy. analysis demonstrated lower compared rivers, aiding prioritising conservation targets inferring distinct assembly processes. Future directions include deeper exploration information detailed multifunctionality quantification refinement scenarios. This study demonstrates promising integration prediction modelling biodiversity loss, offering valuable tool effective management.
