Organic carbon inputs2.1.. Mangrove ecosystem productivityThe most widely used proxy of mangrove productivity is annual litter fall, which is known to show a latitudinal gradient, being highest close to the equator (e.g., Twilley et al., 1992).Typical global average litterfall rates are in the order of 38 mol C m 2 year 1 (Twilley et al., 1992, Jennerjahn and Ittekkot, 2002).

However, rising temperatures and sea level due to climate change are allowing mangroves to expand their ranges farther away from the equator and encroach on temperate wetlands, like salt marshes. Mangroves categorized as secretors, including species in the black mangrove genus. Efforts to remove the invasive mangroves began in the 1980s and are still ongoing. In this Larger predatory fish, turtles, and crabs feed on the primary consumers. Mangrove swamps are coastal wetlands found in tropical and subtropical regions.

These adaptations are so successful that some mangroves are able to grow in soils that reach salinities up to 75 parts per thousand (ppt), about two times the salinity of ocean water.
