5. Overall change of gases fluxes following rewetting and thawing

An analysis of published field and laboratory studies showed that CO2, CH4, N2O, NO and NH3 fluxes increase on average 7.6 times (± standard error 1.1) following rewetting and thawing with no significant difference between these events (R2 = 0.896, P < 0.001; Fig. 3). Similarly, laboratory studies showed that CO2 and N2O fluxes increase on average 5.8 times (± standard error 1.5) following rewetting and thawing with no significant difference between these events (R2 = 0.726, P < 0.001; Fig. 3).
