| description | Coastal wetlands are dynamic, and exhibit spatial variation associated to the intensity of the land-ocean interactions. These wetlands are highly productive, and support relevant environmental services related to anthropogenic climate change mitigation. From a landscape point of view, and assuming that connectivity among coastal processes does exist among coastal processes, the evaluations of the aboveground and belowground C stocks were carried out in eight landscape units, along a wetland continuum located at the northern coast of Yucatan, called “coastal transverse corridor”. The ecosystem C stock for the corridor was 3 837 160 Mg C. The dwarf mangrove presented the largest total carbon stock per unit area (371 Mg C ha-1), being also the dominant in extension. The gradient of the aboveground C stocks followed flood patterns, the elevation of the wetland, interstitial salinity, and the specific tolerance of the species. The mangroves stored more carbon per hectare than wetlands dominated by emergent herbaceous and submerged vegetation. The first ones were dominated by production and accumulation rates of C, while the other two, were dominated by the production, and the recycling which caused a low C storage. The results of this study contribute to the understanding of the C stocks patterns in the salinity and topographic gradients along karst coastal wetlands. The results could be used to evaluate the potential of local and regional effects in the medium and long term caused by natural and anthropogenic impacts. |

Los humedales costeros son dinámicos y su variación depende de la intensidad e interacción entre los procesos continentales y marinos que los influencian. Estos humedales son altamente productivos y sustentan servicios ambientales relevantes para la mitigación de los efectos del cambio climático antropogénico. Considerando un enfoque paisajístico de conectividad entre los procesos costeros, se llevó a cabo la evaluación de los almacenes de C aéreo y subterráneo en ocho humedales. Estos conforman un paisaje continuo en la costa norte de Yucatán denominado corredor transversal costero. El almacén de C para el corredor correspondió a 3 837 160 Mg de C. El humedal de manglar chaparro presentó el mayor almacén de carbono total por unidad de área (371 Mg C ha-1), siendo también el dominante en extensión. El gradiente en el almacén de C aéreo entre humedales obedeció a patrones de inundación, elevación topográfica, salinidad intersticial y la tolerancia específica de las especies. Los manglares almacenaron más carbono por hectárea que los humedales dominados por herbáceas emergentes y por la vegetación sumergida. Los primeros estarían dominados por procesos de producción y acumulación de C, mientras que en los segundos la producción y el reciclamiento serían los más importantes, repercutiendo en una menor acumulación de C. Los resultados contribuyen al entendimiento de los patrones de almacenamiento de C en un gradiente salino y topográfico en paisajes integrados por humedales costeros cársticos. Los resultados podrán utilizarse para evaluar las afectaciones regionales potenciales en el mediano y largo plazo ocasionados por impactos naturales y antropogénicos.
