Abstract
Changes in the concentration of total lipid and fatty acids (FAs) during the decomposition
of mangrove leaves were investigated by field experiments using yellow leaves
of Bruguiera gymnorrhiza (L.) Lamk. and Kandelia candel (L.) Druce, in order to
quantify mangrove contribution to lipid and fatty acid inputs to marine sediments.
Total lipid and total FA in the fresh (green and yellow) and decomposing leaves of
both species were significantly higher during winter than summer. During decomposition,
total lipid content and FA concentration, in particular branched chain fatty
acids (BrFAs) and bacterial fatty acids (BFAs), increased to a maximum concentration
in 45 days during winter and in 17 days during summer. Lipids were lost faster in
K. candel leaf detritus than in B. gymnorrhiza leaf detritus in which >90% of the total
lipid original weight was lost during the summer experiment and <60% during the
winter experiment. The changes in the concentrations of total lipids and FAs in the
decomposing leaves also indicate that mangrove leaves are significant sources of fatty
acids and probably other lipid compounds to estuarine ecosystems and that tidal waters
transport the lipids and FAs adsorbed to particulate matter from mangroves to adjacent
estuarine sediments and the ocean.
