Fig. 8: Conceptual diagram of how hydroclimate process influences N2O fluxes.
From: Global latitudinal patterns in forest ecosystem nitrous oxide emissions are related to hydroclimate
a Hydroclimate processes dominate soil drought and rewetting. b A comparative conceptual diagram of the four main potential mechanisms dominating N2O flux emissions in different forests. The dashed arrows of different colors represent the pathways of influence of different factors on N2O, the thicker the arrow, the greater the influence. Orange, purple, dark blue, and light blue represent the pathways of temperature, clay, wet and dry alternation, and ET effect on N2O flux, respectively. The red solid arrows represent N2O fluxes. Rin incoming shortwave radiation, MAT mean annual temperature, VPD vapor pressure deficit, MAP annual precipitation, ET evapotranspiration, WFPS water-filled pore space.
