ClearArchitecture of soil microaggregates: Advanced methodologies to explore properties and functions
This review covers advanced methodologies for exploring the three-dimensional architecture of soil microaggregates (particles smaller than 250 micrometers), including imaging techniques that reveal pore space, mineral-organic interfaces, and microbial habitats. Understanding microaggregate structure is key to linking soil physical properties with carbon cycling and microbial ecology.
Bacterial and fungal predator – prey interactions modulate soil aggregation
This study examined how predator-prey interactions between bacteria, fungi, and their microbial predators influence soil aggregate formation. While focused on soil ecology, the research is relevant to understanding how microplastic contamination — which alters microbial communities — could indirectly affect soil structure and stability.
Differences, links, and roles of microbial and stoichiometric factors in microplastic distribution: A case study of five typical rice cropping regions in China
Researchers investigated microplastic distribution across five major rice-growing regions in China, finding that microbial community composition and soil stoichiometric factors like carbon-to-nitrogen ratios significantly influenced microplastic accumulation patterns in agricultural soils.
