Tracking the invisible: carbon dioxide flux in an ecotonal wetland
Blog By: Amanda Richey Check out Contributing Bloggers  for Bio   The salty is getting saltier .  A ll around the world, change s in fresh water flow  combined with  intruding saltwater is salinizing coastal freshwater  and brackish wetlands . Salinization  is stressing these transitional habitats , which  leads to  vegetation  loss  and with it, the carbon stored in stems, leaves, and root systems.  Additionally, l ush, freshwater plant communitie s are being replaced  by more salt tolerant species .  Th e variation  in  coastal wetland response to salinization due to water level changes  makes the fate of these systems  uncertain ,  as well as  the fate of the carbon t hey store.  Understanding  carbon dynamics in coastal vegetated ecosystems is essential because  these ecosystems are globally important carbon sinks, and they are at  risk of being lost.       Saltmarsh, mangrove forests, and seagrass meadows are  all  known as “blue carbon” ecosystems because  they  are effi...
