Estimation of the carbon pool in soil and above-ground biomass within mangrove forests in Southeast

We report the results of carbon stored in soil and aboveground biomass from the most important area of mangroves in Mexico, with dominant vegetation of Red mangrove (Rhizophora mangle L.), Black mangrove (Avicennia germinans L.), white mangrove (Laguncularia racemosa Gaertn.) and button mangrove (Conocarpus erectus L.). We sampled soils with high fertility during the dry season in 2009 and 2010 at three sites on Atasta Peninsula, Campeche. We used allometric equations to estimate above ground biomass (AGB) of trees. AGB was higher in C. erectus (253.18±32.17 t?ha-1), lower in A. germinans (161.93±12.63 t?ha-1), and intermediate in R. mangle (181.70±16.58 t?ha-1) and L. racemosa (206.07±19.12 t?ha-1). Of the three studied sites, the highest absolute value for AGB was 279.72 t?ha-1 in button mangrove forest at any single site. Carbon stored in soil at the three sites ranged from 36.80±10.27 to 235.77±66.11 t?ha-1. The Tukey test (p
