Annual cyclicity in high-resolution stable carbon and oxygen isotope ratios in the wood of the mangrove tree Rhizophora mucronata
Verheyden, A.; Helle, G.; Schleser, G. H.; Dehairs, F.; Beeckman, H.; Koedam, N. (2004). Annual cyclicity in high-resolution stable carbon and oxygen isotope ratios in the wood of the mangrove tree Rhizophora mucronata. Plant Cell Environ. 27(12): 1525-1536. dx.doi.org/10.1111/j.1365-3040.2004.01258.x
In the present study, the high-resolution stable carbon ((13)C/(12)C) and oxygen ((18)O/(16)O) isotope ratio profiles in the wood of the mangrove Rhizophora mucronata Lam., a tropical tree species lacking distinct growth rings, were investigated. Variations of both isotope ratios revealed a remarkable annual cyclicity with lowest values occurring at the latewood/earlywood boundary (April-May) and highest values during the transition from earlywood to latewood (October-November). Based on the current knowledge of the physiology of this mangrove species, as well as on the current literature available on high-resolution profiles of stable isotope ratios in tree rings, possible driving forces responsible for this seasonal pattern are discussed. The annual cyclicity, together with a conspicuous isotope pattern appearing in the El-Nino year 1997, promises great potential for tropical dendrochronology.
