ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability. Soil microfauna nematode, protozoa, arthropoda) stabilized entire through top‐down control. rather than or biodiversity predicted dynamics multifunctionality. Specifically, stable communities, both organism groups archaea, bacteria, fungi, arthropoda, viridiplantae, viruses), support high In particular, had more contributions multifunctionality microbial communities. This result was further supported by analysis, which modules 1 4 greater numbers explained Our study highlights should be considered key factor improving sustainability crop productivity context global intensification.

Increasing pesticide diversity impairs soil microbial functions

Proceedings of the National Academy of Sciences, Год журнала: 2025, Номер 122(2)

Опубликована: Янв. 9, 2025

Pesticide application is essential for stabilizing agricultural production. However, the effects of increasing pesticide diversity on soil microbial functions remain unclear, particularly under varying nitrogen (N) fertilizer management practices. In this study, we investigated stochasticity microbes and multitrophic networks through amplicon sequencing, assessed community related to carbon (C), N, phosphorus (P), sulfur (S) cycling, characterized dominant bacterial life history strategies via metagenomics along a gradient two N addition levels. Our findings show that higher enriches abundance specialists opportunists capable degrading or resisting pesticides, reducing proportion generalists in absence addition. These shifts can complicate networks. Under increased diversity, selective pressure may drive bacteria streamline their average genome size conserve energy while enhancing C, P, S metabolic capacities, thus accelerating nutrient loss. comparison, was found reduce niche differentiation at mitigating impacts network complexity functional traits associated with ultimately alleviating results reveal contrasting different input scenarios emphasize strategic mitigate ecological use systems.

Microbial Biotic Associations Dominated Adaptability Differences of Dioecious Poplar Under Salt Stress

Plant Cell & Environment, Год журнала: 2025, Номер unknown

Опубликована: Янв. 2, 2025

How different stress responses by male and female plants are influenced interactions with rhizosphere microbes remains unclear. In this study, we employed poplar as a dioecious model plant quantified biotic associations between microorganisms to explore the relationship microbial adaptation. We propose health index (HI) comprehensively characterize physiological characteristics adaptive capacity of under stress. It was found that poplars demonstrated higher salt tolerance than females, root-secreted citric acid significantly in rhizospheres poplars. Positive association among bacteria increased HI stress, while fungal cross-domain (bacteria-fungi) did not. further identified keystone bacterial taxon regulating association, ASV_22706, which itself regulated positively correlated host HI. The abundance taxa negatively Compared poplars, enriched more prebiotics probiotics This work primarily reveals adaptation differences plants, suggests approach improve adaptability conditions.

The Identification of Patterns in the Relation Between Biodiversity and Mutualistic Ecosystem Function Based on Network Resilience

Entropy, Год журнала: 2025, Номер 27(3), С. 231 - 231

Опубликована: Фев. 24, 2025

Identifying the relation between biodiversity and mutualistic ecosystem function has been a longstanding concern. In this study, we present an interpretive model to evaluate impact of each species on functions. By analyzing network resilience, derive average abundance tipping point represent Based order collapse, is classified according F-core. The quantitatively evaluates influence functions in scenarios where are removed from ecosystems. We propose criterion for identifying redundant species: considered if its removal negatively impacts without affecting point. To validate model, introduce twenty-four Our numerical simulations analytical analyses reveal two distinct patterns: one indicating presence redundancy other suggesting that essential. Additionally, ecosystems characterized by redundancy, specialist more likely be identified as redundant.
