Summary:

Emissions of the nitrogen trace gases nitrous oxide (N(sub 2)O) and nitric oxide (NO) were analyzed at five sites which form a 200 to 4.5 million year chronosequence in Hawaiian montane rainforest. The increasing emissions of N(sub 2)O + NO were associated with increasing soil nitrification and mineralization fluxes. Seasonal and intersite patterns of rainfall and soil density were a strong influence on the magnitude of N(sub 2)O and NO emissions. Root growth and leaf litter assays indicate that mitrogen supply to the plant community may be highest in intermediate age sites.
