Percentage of variation in E s during a given period (ΔE s) in (a) Terra Firme forest (TFF, white box) and (b) seasonally flooded forest (SFF, gray box): long dry season 2007 (LDS07), transition between the dry and the wet period 2008 (DW-T08), long wet season 2008 (LWS08), transition between the wet and the dry period 2008 (WD-T08), long dry season 2008 (LDS08), and transition between the dry and the wet period 2009 (DW-T09). The symbols denote the mean pattern in ΔE s when it was significantly different from zero (p < 0.05), i.e., increase (+) or decrease (−). Overall, there was a significant effect of seasons on ΔE s (df = 490; F = 14.7; p < 0.001) and a significant interaction between habitat and seasons (F = 3.1; p = 0.009), but no significant effect of habitat alone on ΔE s (F = 1.4; p = 0.24)
