Digging deeper: Fine root responses to rising atmospheric [CO2] in forested ecosystems CO2 enrichment increases carbon and nitrogen input from fine roots in a deciduous forest. Increases in nitrogen uptake rather than nitrogen-use efficiency support higher rates of temperate forest productivity under ... Brief communication: Monitoring snow depth using small, cheap, and easy-to-deploy snow–ground interface temperature sensors Divide and conquer: using RhizoVision Explorer to aggregate data from multiple root scans using image concatenation and statistical methods Getting allometry right at the Oak Ridge free-air CO2 enrichment experiment: Old problems and new opportunities for global ch...
