• Reciprocal influence of per- and polyfluoroalkyl substances (PFAS) and soil organic matter on their fate in soils (2025) · Environmental Science and Pollution Research · cited 18× · doi

  While PFAS sorption may depend on the quality of soil organic matter (SOM), their unique properties may also affect SOM dynamics in complex and poorly understood ways, impacting long-term soil quality.

• Contrasting effects of above and belowground litter inputs in shaping the soil microbiome worldwide (2025) · Plant and Soil · cited 1× · doi

  Abstract Background and aims Microbes are the primary decomposers of litter, yet how above and belowground litter inputs contribute to soil microbial structure and function remains unclear across global environmental gradients.

• Effect of soil microorganisms and labile C availability on soil respiration in response to litter inputs in forest ecosystems: A meta‐analysis (2020) · Ecology and Evolution · cited 84× · doi

  Litter inputs can influence soil respiration directly through labile C availability and, indirectly, through the activity of soil microorganisms and modifications in soil microclimate; however, their relative contributions and the magnitude of any effect remain poorly understood.
