Importance of Mangrove Plants for Global Carbon Cycle
... An analysis of the impact of mangrove plants on marine carbon inventories suggests that the mangroves account for more than 10% of the terrestrially derived dissolved organic carbon transported to the ocean, while they cover only 0.1% of the continents’ surface. The worldwide rapid decline of mangro ...
