Leaf Gas Exchange and Nutrient Use Efficiency Help Explain the Distribution of Two Neotropical Mangroves under Contrasting Flooding and Salinity

Figure 4

Photosynthetic nitrogen use efficiency (PNUE) and leaf nitrogen (N) concentration of Laguncularia racemosa (L) and Rhizophora mangle (R) in response to tidal flooding (TF) or permanent flooding (PF) with 10 g/L (10S) or 40 g/L (40S) salinity. Values are means ±  1SE. Effects annotated with the same letter above the bar (for PNUE) indicate lack of significance ( ) after Bonferroni adjustment.
