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

Table 3 Mean ± 1 s.d. monthly total net ecosystem CO2 exchanges during daytime (-sum symbolNEEday) nighttime (sum symbolNEEnt), and daytime plus nighttime 24-h CO2 exchange (-sum symbolNEEtot) for dry (November to May) and wet (June to October) seasons before and after Hurricane Wilma. Similar letter superscripts in columns identify results that are not significantly different (P > 0.05) within each season using a two-sided t-test with Bonferroni correction.
