(a) The difference between the carbon isotopic composition (Δδ¹³C) of bound amino acids in fresh leaves from dwarf and tall Red mangrove, range bars are representative biosynthetic variation between the three leaves from each red mangrove stand. (b) The difference between the carbon isotopic composition (Δδ¹³C) of bound amino acids in 'PL dwarf' (n = 3) and 'PL tall' (n = 3). error bars are representative of ± one standard deviation from the mean. Key: alanine (ala), threonine (thr), serine (ser), valine (val), iso-leucine (ileu), hydroxy-proline (hyp), proline (pro), aspanic acid (asp), glutamic acid (glu), phenylalanine (phe), lysine (lys), tyrocine (tyr).
