Global rice methane emissions tripled over six decades amid declining emission intensity

Abstract Rice paddies are among the largest anthropogenic sources of methane (CH4), yet substantial uncertainties persist in the long-term magnitude and spatiotemporal dynamics of the emissions. Here we show a spatially explicit global estimate of rice CH4 emissions from 1961 to...

Fungal necromass dominates soil organic carbon accrual after decadal active restoration of alpine grassland

Active (seeding native grasses) and passive (natural recovery via degradation factor removal) restoration practices regulate soil organic carbon (SOC) recovery in degraded grasslands through distinct mechanisms. We quantified microbial- (amino sugars) and plant-derived (lignin ph...
