An experimental model system to investigate microscale mechanisms behind the soil priming effect

This paper introduces a microfluidic model system to study soil microbial responses to labile substrate pulses, observing concentration-dependent decomposition and microbial behavior.

Arbuscular mycorrhizal fungal families and exploration-based guilds exhibit distinct responses to N, P and K deficiencies and imbalances

The paper examines how N, P, and K deficiencies and imbalances affect arbuscular mycorrhizal fungal (AMF) communities and their guilds in a long-term grassland experiment.

Model substrate particles uncover dynamics of microbial communities associated with particulate organic matter decomposition in soil

This study uses model substrate particles to investigate how chitin and cellulose influence microbial community dynamics in soil over time.

Microbial community regulation of extracellular enzyme production can mediate patterns of particulate and mineral-associated organic matter accumulation in undersaturated soils

The paper models microbial enzyme production and its impact on organic matter storage in soils, showing that social dynamics among microbes influence POM and MAOM formation.

Environmental context shapes microbial co-occurrence

The paper examines how environmental factors and sampling strategies influence microbial co-occurrence patterns using a simulated dataset.

Strengths of relationships among soil microbial and organic matter properties are scale-dependent

This study shows that relationships between soil microbial and organic matter properties vary with observation scale, with aggregates providing more accurate insights than bulk soil samples.

Soil bacterial neutral lipid fatty acids: Markers for carbon storage or necromass?

This paper investigates the origin of soil bacterial neutral lipid fatty acids (NLFAs), finding they primarily derive from carbon storage rather than necromass.

Soil microbes prefer organic acids over sugars in simulated root exudation

In intact meadow and forest soil cores, 13C-labelled acetate and succinate released by reverse microdialysis left the exudation spot faster and were respired more than glucose and fructose.

Distinct microbial communities are linked to organic matter properties in millimetre-sized soil aggregates

This study links microbial communities in millimetre-sized soil aggregates to their physico-chemical properties, showing distinct communities and environmental relationships.
