Mangroves are among the most productive and biologically complex ecosystems on Earth. For most plants, the seeds remain dormant until after they are dispersed to a favorable environment. They are also important because they provide a habitat for other species that live in the ecosystem, like fish and birds. >> All mangroves have evolved special adaptations that enable them to live in salty, oxygen-poor soil. Producers are organisms that create food from inorganic matter. ), oysters (Crassostrea spp. At smaller scales, bacteria and fungi are major decomposers in mangrove ecosystems.

The primary consumers of mangroves are usually the decomposers (e.g. The bats, mostly concerned with just getting a sweet meal, are unknowingly helping the mangroves by pollinating their flowers. The fish breathe by storing water in their mouth and gill chamber, and by keeping their skin damp they can also breathe air through their skin. the mangrove tree crab). They stabilize shores by trapping sediments and building land. Treating animal hides with tannin alters the hides protein structure so it becomes soft, pliable, and resistant to decomposition. /Parent 3 0 R This type of plant reproduction is called vivipary.

Detritivores (also known as detrivores, detritophages, detritus feeders, or detritus eaters) are heterotrophs that obtain nutrients by consuming detritus (decomposing plant and animal parts as well as feces ). These wetlands are often found in estuaries, where fresh water meets salt water and are infamous for their impenetrable maze of woody vegetation. Many kinds of birds nest, roost, and feed in mangroves. The salty soils of the intertidal pose an inhospitable barrier for most woody plants, but the mangrove is uniquely adapted for these conditions. Frogs cling to bark and leaves. Nutrients like carbon, nitrogen and phosphorous are key to the health of plants. As the salty water evaporates, noticeable salt crystals often form on the surface of the leaves. >> /RoleMap 25 0 R In the Americas, Aratus pisonii, the mangrove tree crab, can cling to tree bark as well as to wooden docks and pilings. >> /CropBox [0 0 612 792] In just the last decade, at least 35 percent of the world's mangroves have been destroyed.

Estuary - a partially enclosed body of water where two . Sometimes the crabs chase male competitors all the way back to their burrows. << Some species like Conocarpus erectus, the buttonwood, are often grouped with mangroves since they hug the upper edge of mangrove forests, however, they lack many of the characteristic adaptations of mangroves and are labeled mangrove associates. When all plants that live in a mangrove environment are accounted for, there are well over 80 mangrove species. Using their claws, they move the mud onto mounds aboveground, in some cases up to three meters tall. They cover between roughly 53,000 and 77,000 square miles (138,000 and 200,000 square km) globally, acting as a bridge connecting the land and sea. /URI (https://research.bangor.ac.uk/portal/en/researchers/christian-dunn\(fe8e7d0e-d788-47ba-9674-243648c382cb\).html) A 2006 study found the Mantang mangrove forest in West Malaysia supports fisheries worth 100 million dollars per year. Mangrove forests occurring at the interface of terrestrial and marine ecosystems represent a rich biological diversity of plants, animals and microorganisms.
