In mangroves as well as in other forest ecosystems, the importance of assessing carbon storage and flows is recognized by the contributionthat they may have in mitigation of the effects of CO2 emissions. This study evaluated the relationship between salinity as a hydrologicalcontroller and the carbon storages and flows in fringe mangroves of a geomorphologic karstic scenario with saline gradient like that ofthe Celestún lagoon. Two sampling sites were established in the fringe mangrove, one in the low salinity zone (< 20 psu, internal) and theother in the high salinity zone (> 40 psu, mouth). The structure of the vegetation between sites is different; the dominant species of mangrovein the zone of lower salinity was Laguncularia racemosa, whereas in the high salinity zone it was Avicennia germinans. In the fallof leaf litter there were no significant differences between sites, although it was greater in internal area (4.7 Mg C ha-1 year-1 ± 0.77 Mg Cha-1 year-1) with respect to the area of the mouth (4 Mg C ha-1 year-1 ± 0.38 Mg C ha-1 year-1). It was observed that the concentration ofinterstitial salinity had a significant effect on the total carbon storage, being greater in the Internal zone (375 Mg C ha-1 ± 9.6 Mg C ha-1).In the Internal zone the litterfall decomposition rates are lower (t50 > 130 days), causing that, together with greater fall of leaf litter andlower export by the flow-ebb of the tide the accumulation of organic matter on the ground is favored.

En los manglares, como en otros ecosistemas arbóreos, es importante evaluar los almacenes y flujos de carbono orgánico por la contribuciónque pueden tener para mitigar los efectos de las emisiones atmosféricas de CO2. En este estudio se evaluó la relación entre la salinidad,como controlador hidrológico, y los almacenes y flujos de carbono en manglares de franja de un escenario geomorfológico cársticocon gradiente salino como el de la laguna de Celestún. Se establecieron dos sitios de muestreo en el manglar de franja, uno en la zona debaja salinidad (< 20 ups, interna) y otro en la zona de alta salinidad (> 40 ups, boca). La estructura de la vegetación entre sitios es diferente;en el manglar de la zona de menor salinidad la especie dominante fue Laguncularia racemosa, mientras que en el de alta salinidadfue Avicennia germinans. En la caída de hojarasca no se registraron diferencias significativas entre sitios. En la zona interna se obtuvoun valor de 4.7 Mg C ha-1 año-1 ± 0.77 Mg C ha-1 año-1 con respecto a la zona de la boca (4 Mg C ha-1 año-1 ± 0.38 Mg C ha-1 año-1).Se observó que las condiciones contrastantes en la salinidad intersticial tuvieron efecto significativo en el almacén de carbono total, siendomayor en la zona interna (375 Mg C ha-1 ± 9.6 Mg C ha-1). En esta misma zona las tasas de descomposición de hojarasca fueron másbajas (t50 > 130 días), lo cual, junto con una mayor caída de hojarasca y una menor exportación por el flujo-reflujo de la marea, favorecela acumulación de materia orgánica en el suelo.
