Supporting evidence — 8 representative gaps

• Consecutive melon monocropping is associated with microbial community homogenization and reduced bacterial network complexity (2026) · Frontiers in Microbiology · doi

  The long-term associations between bio-organic fertilizers and microbial community structure and ecosystem functioning are not fully understood. The effects of consecutive melon monocropping on soil microbial communities, using Bacillus subtilis-based bio-organic fertilizer, are not well studied.

• Divergent group-specific pathways of microbial diversity and network complexity maintain soil multifunctionality during alpine grassland restoration (2026) · Frontiers in Plant Science · doi

  The study identifies a gap in our understanding of the group-specific pathways linking microbial diversity, community assembly, and network complexity to soil multifunctionality during alpine grassland restoration. The research highlights the need for a more nuanced understanding of the relationships between microbial communities and ecosystem functioning in the context of restoration.

• Perennial vegetative strips promote spillover of beneficial soil microorganisms into adjacent crop field (2026) · Scientific Reports · doi

  The below-ground influence of PVS on soil microbial communities is not well understood. Prior work has not fully addressed the effects of PVS on soil microbial communities. There is a need to understand the mechanisms of microbial spillover and its potential applications for sustainable agricultural management.

• Pioneer vegetation shapes soil microbial community assembly and ecosystem functions in riparian sand mining sites (2026) · Scientific Reports · doi

  The study identifies the challenge of understanding the complex relationships between pioneer vegetation and soil microbial communities. The paper notes the difficulty of elucidating the regulatory mechanisms of pioneer vegetation on soil microbial communities and ecosystem functions. The study highlights the need to investigate the specific mechanisms by which pioneer vegetation modulates soil microbial communities.
