Large biases in the frequency of water limitation across Earth system models - Communications Earth & Environment
CMIP6 Earth system models overestimate the frequency of water-limited conditions on land, by about 14% globally and 26% in the tropics, according to analyses using solar-induced fluorescence, satellit...

Long‐Term Atmospheric Nitrogen Deposition Enhances Forest Production by Suppressing Microbial Competition for Phosphorus
Ecological stoichiometry predicts that long-term nitrogen (N) deposition intensifies phosphorus (P) limitation, yet this remains untested in canopy N addition (CN) experiments that consider critical ...
