N₂O emission associated with shifts of bacterial communities in riparian wetland during the spring thawing periods.

ABSTRACT: Soil freeze-thaw processes lead to high nitrous oxide (N₂O) emissions and exacerbate the greenhouse effect. The wetlands of the Inner Mongolia Plateau are in the pronounced seasonal freeze-thaw zone, but the effect of spring thaw on N₂O emissions and related microbial mechanisms is still unclear. We investigated the effects of different periods (freeze, freeze-thaw, and thaw) on soil bacterial community diversity and composition and greenhouse gas emissions during the spring freeze-thaw in the XiLin River riparian wetlands in China by amplicon sequencing and static dark box methods. The results showed that the freeze-thaw periods predominantly impact on the diversity and composition of the bacterial communities. The phyla composition of the soil bacteria communities o
