Integrating Microbial Community Data Into an Ecosystem‐Scale Model to Predict Litter Decomposition in the Face of Climate Change Open
Litter decomposition is an important ecosystem process and global carbon flux that has been shown to be controlled by climate, litter quality, and microbial communities. Process‐based ecosystem models are used to predict responses of litte…

Agricultural Soil Carbon: A Call for Improved Evidence of Climate Mitigation Open
We identify the critical need for causal approaches to be employed at the scale of commercial agriculture to build high-quality evidence for measurement, monitoring, reporting and verification (MMRV) to quantify the effectiveness of soil c…

Microbe-induced coordination of plant iron–sulfur metabolism enhances high-light-stress tolerance of Arabidopsis Open
High-light stress strongly limits agricultural production in subtropical and tropical regions owing to photo-oxidative damage, decreased growth, and decreased yield. Here, we investigated whether beneficial microbes can protect plants unde…

A common ericoid shrub modulates the diversity and structure of fungal communities across an arbuscular to ectomycorrhizal tree dominance gradient Open
Differences between arbuscular (AM) and ectomycorrhizal (EcM) trees strongly influence forest ecosystem processes, in part through their impact on saprotrophic fungal communities. Ericoid mycorrhizal (ErM) shrubs likely also impact saprotr…

Investigating terrestrial biogeochemical responses to enhanced rock weathering for carbon capture in a whole-watershed experiment Open
Enhanced weathering (e.g., spreading crushed silicate rock on agricultural fields) is a promising approach for carbon sequestration. As rainwater weathers the crushed rock, atmospheric CO2 is converted to bicarbonate, which is transported …

Testing the feasibility of quantifying change in agricultural soil carbon stocks through empirical sampling Open
There is disagreement about the potential for regenerative management practices to sequester sufficient soil organic carbon (SOC) to help mitigate climate change. Measuring change in SOC stocks following practice adoption at the grain of f…

Integrating airborne remote sensing and field campaigns for ecology and Earth system science Open
In recent years, the availability of airborne imaging spectroscopy (hyperspectral) data has expanded dramatically. The high spatial and spectral resolution of these data uniquely enable spatially explicit ecological studies including speci…

The Snowmelt Niche Differentiates Three Microbial Life Strategies That Influence Soil Nitrogen Availability During and After Winter Open
Soil microbial biomass can reach its annual maximum pool size beneath the winter snowpack and is known to decline abruptly following snowmelt in seasonally snow-covered ecosystems. Observed differences in winter versus summer microbial tax…

Report from Lawrence Berkeley National Laboratory on the mechanisms of Actagro product - <em>Proximus</em> (AWD2725) Open
Under a collaborative research and development (CRADA) agreement, LBNL scientists investigated the effect of the semi-humic substance, Proximus, on nitrogen dynamics in two contrasting soils. We specifically tested four hypotheses that Pro…
