Aridity-induced energy reallocation from green to brown food webs predicts grassland carbon storage (opens in new tab)

Proceedings of the National Academy of Sciences, Volume 123, Issue 25, June 2026. SignificanceAridity is intensifying across global grasslands, yet its impacts on soil food-web energetics governing soil carbon sequestration remain unclear. Using a 4,000-km natural aridity gradient across temperate and alpine grasslands, we show that ...
