N(2) Fixation Associated with Decaying Leaves of the Red Mangrove (Rhizophora mangle).
N(2) (C(2)H(2)) fixation was associated with decaying leaves of Rhizophora mangle. The process was predominantly anaerobic, with about two-thirds of the nitrogenase activity being light dependent. Average N(2) fixation rates in the light were 11 mug of N per g (dry weight) per h for leaves that had decayed for 2 to 3 weeks. This nitrogen input is probably significant in the estuarine, detrital food chains linked to R. mangle.
