Primary tropical forests generally exhibit large gaseous nitrogen (N) losses, occurring as
nitric oxide (NO), nitrous oxide (N2O) or elemental nitrogen (N2). The release of N2O is of …

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 …

Nitrogen (N) deposition is projected to substantially increase in the tropics over the coming
decades, which is expected to lead to enhanced N saturation and gaseous N emissions …

Increasing nitrogen (N) deposition in subtropical forests in south China causes N saturation,
associated with significant nitrate (NO3−) leaching. Strong N attenuation may occur in …

Globally, tropical forest soils represent the second largest source of N 2 O and NO. However,
there is still considerable uncertainty on the spatial variability and soil properties controlling …

Studies that quantify nitrous oxide (N 2 O) fluxes from African tropical forests and adjacent
managed land uses are scarce. The expansion of smallholder agriculture and commercial …

Recent atmospheric studies have evidenced the imprint of large N 2 O sources in
tropical/subtropical lands. This source might be attributed to agricultural areas as well as to …

Nitrogen (N) enrichment of tropical ecosystems is likely to increase with rapid industrial and
agricultural development, but the ecological consequences of N additions in these systems …

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 …

The isotopic signatures of 15N and 18O in N2O emitted from tropical soils vary both spatially
and temporally, leading to large uncertainty in the overall tropical source signature and …
