• Divergent rhizosphere microbial necromass dynamics between two plant species in response to water addition in a semi-arid region (2026) · Scientific Reports · doi

  Abstract Microbial necromass carbon influences soil organic carbon (SOC) persistence, yet its response to soil moisture change in semi-arid rhizospheres remains unclear.

• Solid‐phase organic matter reduction regulates anaerobic decomposition in bog soil (2013) · Ecosphere · cited 80× · doi

  However, for reasons which are not well understood, many peatland soils produce smaller amounts of CH 4 than theoretically predicted, and carbon dioxide (CO 2 ) produced during anaerobic decomposition in peatland soils cannot be accounted for by commonly measured microbial processes.

• Soil Respiration Response to Simulated Precipitation Change Depends on Ecosystem Type and Study Duration (2022) · Journal of Geophysical Research Biogeosciences · cited 29× · doi

  Abstract Soil respiration—the flow of biologically‐generated CO 2 from the soil surface to the atmosphere—is a major component of global carbon cycling, but the long‐term response of this flux to altered precipitation regimes remains uncertain, due to different responses of soil respiration in distinct ecosystems with varying degrees of water limitation.

• Extending the least-cost theory of stomatal regulation to include soil moisture stress (2026) · bioRxiv (Cold Spring Harbor Laboratory) · doi

  The lack of mechanistic grounding for soil moisture constraints on carbon and water fluxes in terrestrial biosphere models. The need for a more coherent alternative to existing soil moisture parameterisations.

• Reduced legacy precipitation decreases microbial community growth efficiency and alters soil organic carbon in a California grassland (2026) · Microbiome · doi

  The effects of reduced winter precipitation on microbial community growth efficiency and soil organic carbon are not well understood. There is a need for quantitative assessments of carbon allocated to new growth relative to CO2 production.

• Elevated CO2 Alters Plant–Soil Nutrient Dynamics and Exacerbates Nutrient Dilution: A Field Comparison of Legume and Non-Legume Crops (2026) · Agronomy · doi

  The responses among crop species with contrasting functional traits are not well understood. The effects of elevated CO2 on plant-soil nutrient dynamics and nutritional quality are not fully investigated.
