Nitrous Oxide Emissions from Ephemeral Wetland Soils are Correlated with Microbial Community Composition.

ABSTRACT: Nitrous oxide (N(2)O) is a greenhouse gas with a global warming potential far exceeding that of CO(2). Soil N(2)O emissions are a product of two microbially mediated processes: nitrification and denitrification. Understanding the effects of landscape on microbial communities, and the subsequent influences of microbial abundance and composition on the processes of nitrification and denitrification are key to predicting future N(2)O emissions. The objective of this study was to examine microbial abundance and community composition in relation to N(2)O associated with nitrification and denitrification processes over the course of a growing season in soils from cultivated and uncultivated wetlands. The denitrifying enzyme assay and [Formula: see text] pool dilution methods were used to compare
