Soil respiration is an important component of the carbon (C) cycle and a major contributor to
total ecosystem C efflux. Knowledge of the factors that drive soil respiration in drylands is …

The soil CO2 efflux (Fs) remains the least constrained component of the terrestrial carbon
cycle; its estimates are still largely uncertain, mainly because of its considerable variation …

In Mediterranean ecosystems, the soil biological crust (hereafter biocrust) plays a crucial
role in maintaining ecosystem functioning. In these ecosystems, soil water content can often …

Due to their large carbon storage capacity and ability to exchange subterranean CO2 with
the atmosphere, soils are key components in the carbon balance in semi‐arid ecosystems …

The metabolic activity of water-limited ecosystems is strongly linked to the timing and
magnitude of precipitation pulses that can trigger disproportionately high (ie, hot-moments) …

A better understanding of temporal and spatial variability of soil CO2 fluxes is essential to
improve model predictions of soil effluxes. To accomplish that goal, high‐frequency and long …

We seek to understand how biophysical factors such as soil temperature (Ts), soil moisture
(θ), and gross primary production (GPP) influence CO2 fluxes across terrestrial ecosystems …

Soil fluxes of CO2 (Fs) have long been considered unidirectional, reflecting the predominant
roles of metabolic activity by microbes and roots in ecosystem carbon cycling. Nonetheless …

The temperature dependance of soil respiration has most commonly been addressed using
surface flux data, despite the fact that surface flux measurements implicate CO2 transport …

There is growing evidence that dryland soils could act as substantial but so far disregarded
carbon sinks at the global scale. In drylands, potential abiotic processes of CO 2 uptake are …
