• Elevation modulates the effects of tourism disturbance on soil fungal and bacterial communities in a cold-temperate montane forest (2026) · Frontiers in Microbiology · doi

  The effects of tourism disturbance on soil microbial communities are unclear. The interactions between elevation and tourism disturbance on soil microbial communities are not well understood. The relationships between soil physicochemical properties and microbial community composition require further investigation.

• Elevation modulates the effects of tourism disturbance on soil fungal and bacterial communities in a cold-temperate montane forest (2026) · Frontiers in Microbiology · doi

  The study faced challenges in selecting representative sampling units due to the complex terrain and vegetation conditions. The research required careful consideration of the interactions between elevation and tourism disturbance on soil microbial communities. The paper mentions the need to account for differences in sequencing depth among samples, but does not elaborate on the challenges faced.

• Shelter for microbes? Quantitative insights into soil microbial communities in shelterbelt agroforestry systems (2026) · Agroforestry Systems · cited 1× · doi

  Soil microorganisms are sensitive to environmental conditions. The choice of soil sampling depth can strongly influence results. There is a lack of quantitative insights into the effects of shelterbelts on soil microorganisms.

• The illusion of diversity: sampling design drives conflicting estimates of soil bacterial richness (2026) · bioRxiv · doi

  The impact of sampling design on soil microbial diversity estimates is not well understood. The effects of physical homogenization on diversity estimates are not well characterized. There is a need for a framework to evaluate the impact of sampling design on soil microbial diversity estimates.
