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

Table 2 Mean ± 1 s.d. of daytime (10:00-14:00 h) half-hourly sensible (H) and latent (LE) heat fluxes, ratios of net to solar irradiance (Rnet/Kin), H/Rnet, LE/Rnet, soil heat fluxes (G), and energy closure ((H + LE)/(Rnet - G)) 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 > 0.01) within each season during daytime or nighttime periods using a two-sided t-test with Bonferroni correction.
