Abstract An ex-situ 15 N–18O tracing experiment with soils collected from the valley and
slope, respectively, of a subtropical secondary karst forest with three N addition levels, ie, 0 …

Subtropical acidic forest soil is an important source of global nitrous oxide (N2O). However,
the rates of autotrophic nitrification and denitrification in such soil are less than in temperate …

Soil N 2 O responds differently to various soil variables; moreover these driving variables
usually have low explanatory capacity of soil N 2 O flux variability. Anthropogenic nitrogen …

Topography can influence nitrous oxide (N2O) emission via its influences on soil nutrient
availability, moisture, and microbial communities. Nevertheless, it is still unclear whether …

Atmospheric nitrogen (N) deposition is rapidly increasing in tropical regions. We
investigated how a decade of experimental N addition (125 kg N ha− 1 year− 1) to a …

Anthropogenic nitrogen (N) deposition may substantially affect the contributions of ammonia-
oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) to soil nitrous oxide (N 2 O) …

In tropical forests, multi-year studies on the impact of chronic nitrogen (N) enrichment on soil
N-oxide fluxes are lacking. Our objectives were to:(1) assess the changes in soil N-oxide …

Elevated nitrogen (N) deposition has induced substantial impacts on the emissions of
nitrous oxide (N2O) from forest ecosystems, but how soil microbes regulate the production …

Nitrous oxide (N2O) dynamics during denitrification, including N2O production and
reduction, particularly as related to soil depth, are poorly understood. The objective of this …

Acidic subtropical forest soils, receiving high atmospheric nitrogen (N) deposition, are
characterized by fast N turnover, making them potential “hot spots” for nitrous oxide (N 2 O) …
