Description
Changxing Zhao's team used a meta-analysis of 2,100 site-years of root and germ respiration across 163 sites to ask how global change shifts belowground seasonal timing. Aboveground phenology is well tracked, but root and microbe calendars remain poorly characterised.
Root and germ seasons usually shifted asymmetrically, except for a symmetric advance of season onset under warming. Heat plus nitrogen lengthened root seasons, while germ seasons lengthened with warming and drying but shortened after partial vegetation removal. Warming-driven germ extension alone could raise global heterotrophic respiration by about two and a half petagrams of carbon yearly, a flux Earth system models should now represent.
