| description | In this study, we made a review about carbon stocks and fluxes in Mexican freshwater wetlands. Data for carbon storage in roots, soil and biomass has been reported for marshes, forested wetlands and flooded grasslands in southeast Mexico: Veracruz, Chiapas and Yucatán. The largest carbon stock in freshwater wetlands is the soil (150 Mg C ha-1 a 650 Mg C ha-1) and the forested wetlands showed the highest values. The carbon stock in the biomass ranges from 10 Mg C ha-1 to 162 Mg C ha-1, and forested wetlands showed the highest values. Carbon fluxes measured as litter fall has been reported for forested wetlands in Veracruz (6 Mg C ha-1 year-1 a 9 Mg C ha-1 year-1) only. Methane and carbon dioxide fluxes ranged from 0.01 mg C m-2 d-1 to 1244 mg C m-2 d-1, and 0.009 g C m-2 d-1 to 11 g C m-2 d-1 respectively for Veracruz and Tabasco wetlands. Such carbon fluxes increased up to ten times, when wetlands are transformed to grasslands. It is concluded that the number of publications and study sites on carbon dynamics in Mexican freshwater wetlands is still very small. Therefore, it is necessary to increase the research in this area and enact laws that protect these important carbon sinks. |

Este trabajo hace una revisión bibliográfica sobre los almacenes y flujos de carbono en humedales de agua dulce en México. Se encontraron datos sobre almacenes de carbono en suelo, biomasa aérea y raíces en humedales herbáceos (popales, tulares y carrizales), humedales arbóreos (selvas inundables y palmares) y en humedales transformados en potreros que aún se inundan, para tres estados del sureste mexicano: Veracruz, Yucatán y Chiapas. El mayor almacén de carbono se ha registrado para el suelo de las selvas inundables (150 Mg C ha-1 a 650 Mg C ha-1). Los almacenes de carbono en la biomasa área de las selvas inundables fueron de 10 Mg C ha-1 a 162 Mg C ha-1, siendo también los valores más altos. Con respecto a los flujos de carbono medidos como caída de hojarasca en selvas inundables, solo se encontraron datos para Veracruz (6 Mg C ha-1 año-1 a 9 Mg C ha-1 año-1). Los flujos de metano y bióxido de carbono estuvieron en el intervalo de 0.01 mg C m-2 d-1 a 1244 mg C m-2 d-1 y 0.009 g C m-2 d-1 a 11 g C m-2 d-1 respectivamente, para Veracruz y Tabasco, y dichas emisiones aumentan hasta 10 veces en humedales transformados en potreros. Se concluye que aún son muy pocas las publicaciones y pocos los sitios estudiados sobre la dinámica del carbono en humedales de agua dulce, por lo que hay que incrementar la investigación en esta línea, ya que los humedales son importantes sumideros de carbono y es necesaria una legislación que proteja las reservas de carbono en estos ecosistemas.
