Hurricane Disturbance and Recovery of Energy Balance, CO2 Fluxes and Canopy Structure in a Mangrove Forest of the Florida Everglades

Table 4 Mean ± 1 s.d. of the differences between modeled (Eq. (1)) and observed monthly total daytime net CO2 exchange -(sum symbolNEEday,mod - sum symbolNEEday,obs), nighttime net CO2 exchange (sum symbolNEEnt,mod - sum symbolNEEnt,obs), and net daytime plus nighttime 24-h CO2 exchange -( sum symbolNEEtot,mod - sum symbolNEEtot,obs) after Hurricane Wilma. P-values were determined by comparing mean differences in modeled and measured values to zero using a one-sided t-test.
