Microbial survivability during repeated extreme dry-wet cycles determines CO2 emissions after rewetting of dried soils in humid temperate forests

Shifts in precipitation patterns with less frequent rain events accompanied by global warming will trigger soil drying and rewetting, even in humid regions. Because rewetting of dried soil provokes pulse carbon dioxide (CO2) emissions from soils, the chronic soil dry-wet cycle (DWC) in humid regions may provide positive feedback, contributing to global warming. In this study, we aimed to reveal the effects of repeated DWCs on soil CO2 emissions, and the factors affecting emissions after rewettin
