Exploring the overflow tap theory: linking forest soil CO2 fluxes and individual mycorrhizosphere components to photosynthesis
A study of a temperate deciduous oak forest in south east England analyzed the components of soil CO2 efflux (Rs), finding that autotrophic respiration (Ra)—comprising root (Rr) and mycorrhizal hyphae (Rm) respiration—contributes 56% of the total flux, with Rm acting as a carbon "overflow tap" linked to gross primary productivity (GPP).

Soil respiration: implications of the plant-soil continuum and respiration chamber collar insertion depth on measurement and modelling of soil CO2 efflux rates in three ecosystems
This research paper examines how the depth of soil collar insertion affects the measurement of soil CO2 efflux across three different ecosystems, finding that collar insertion typically underestimates total soil respiration by severing surface roots.
