Abstract:
This is a commentary on Brookshire et al. 26, 5404-5413 For the Northern Great Plains, Brookshire, Stoy, Currey, and Finney (Global Change Biology, 2020) analyze satellite-based reconstructions of greenness and foliar nutrition and isotopic composition from herbarium samples. Their results of greater productivity coupled with reduced N availability are part of an inflection in our understanding of the global N cycle as much of the terrestrial biosphere appears to be experiencing reduced N availability.
