(a) Compound specific isotopic analysis (δ¹⁵N) of bound amino acids in fresh dwarf Red mangrove (open circles; n = 1) and fresh tall Red mangrove (solid dots; n = 1) leaves. The lines represent the δ¹⁵ N of the bound hydrolysate fraction extracted from dwarf red mangrove (light gray line) and tall red mangrove (dark gray line) leaves. (b) Compound specific isotopic analysis (δ¹⁵N) of bound amino acids in 'PL dwarf' (open circles; n = 1) and 'PL tall' (solid dots; n = 1). The lines represent the δ¹⁵N of the bound hydrolysate fraction extracted from 'PL dwarf' (light gray line) and 'PL tall' (dark gray line).
