A fish living in a tree sounds like a fictional childrens tale, however, in some mangrove forests in the Indo-Pacific Region, its the real deal. Since leaf cells can hold a large volume of water when compared to all other cells, salt is drawn to the leaves as a mechanism to balance the salt concentration. Initially, governments were ill-equipped to regulate this type of farming, and farmers were unaware of the destruction they were causing. The Sundarbans Forest, a UNESCO World Heritage site at the mouth of the Ganges, Brahmaputra, and Megha Rivers in the Bay of Bengal fronting India and Bangladesh, is a network of muddy islands and waterways that extends roughly 3,860 square miles (10,000 square km), two times the size of the state of Delaware.

Eventually, the leaves age and fall off the tree, taking the salt with them. Charcoal from mangroves is highly prized in Japan. In the Americas, Aratus pisonii, the mangrove tree crab, can cling to tree bark as well as to wooden docks and pilings. They in turn support their predators like bigger aquatic animals - amphibians . Based upon findings that seedlings do best when they are submerged for 30 percent of the time and dry for the remaining 70, Lewis and a team of engineers modified the coastal landscape by moving piles of dirt with bulldozers and backhoes away from the experiment site. The introduction of mangrove forests on Hawaii has particularly impacted native birds that are unable to roost in the mangroves and are preyed upon by nonnative rats and mongooses that hide in the mangrove roots.

Aquaculture, coastal development, rice and palm oil farming, and industrial activityare rapidly replacing these salt-tolerant trees and the ecosystems they support. 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. These shallow-water ecosystems support a rich food chain with plenty of toothy predators. http://www.olicognography.org/drawings/mangroveecosytem.jpg https://environmentaleducationasia.files.wordpress.com/2014/03/food-web-bio-revised-version.jpg Due to deforestation, they are, Dive underwater in the surprisingly clear waters that typify many mangrove forests, and a, suddenly take on the textures and hues of the multitude of marine organisms clinging to its bark. 10, percent.

The mangrove forests from the tip of Florida to the Carribean are home to another marine reptile, the American crocodile, a species once endangered but now, thanks to conservation efforts, is listed as, on the IUCN red list. 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. The trophodynamics difference of OPEs may be attributed to food chain length, feeding habits and habitat of organisms, and biotransformation of OPEs in organisms. Once the leaves and older trees die they fall to the seafloor and take the stored carbon with them to be buried in the soil. Food web structure in exotic and native mangroves: a Hawaii - PubMed Extensive mangrove diebacks in Australia along the Bay of Carpentaria in the Northern Territory and at Exmouth in Western Australia have been linked to a 14 inch (35 cm) drop in sea level, which when coupled with prolonged drought, left mangroves high and dry long enough to cause extensive mangrove death.
