New Zelndia

The majority of the manguezais places it 30 degrees of the equator, but some resistant types if adaptam the tempering climates as the fens of the New Zelndia, distant of the tropical sun. But, where it wants that the fens live, a thing have in common: TALENT Adapt fen possesss a system of ultrafiltering that hinders the absorption of good part it salt and a complex system of roots that allows it to survive in the zone entremars. Some possess called, hollow pneumatforos roots as one snorkel1, that they are projected on the silt and they allow the breath of> plant. Others use adventitious roots as shoring to exactly keep its erect trunk in the soft sediments of the edge of the tide. In Brazil, the manguezais distribute since the extremity north of the Amap until the city of Lagoon in Santa Catarina, occupying an area esteem in 26000 km2, being composed for 6 typical, pertaining arbreas species the 3 sorts: Rhizophora mangle (red fen), Rhizophora harrisonii, racemosa Rhizophora, aschaueriana Avicennia (black fen, cano), Avicennia germinans (fen siriba) and racemosa Laguncularia (white fen) .2. Importance of manguezalO high value of the manguezais inhabits in the protection to the shoreline that they offer, in the maintenance of the quality of the water, in its raised biological productivity and the condition to propitiate shelter, habitat and feeding to a great number sea and terrestrial species. These ecosystems are between most productive and are considered ecosystem-key since it comes a great variety from natural resources and services ambient that they give to support the economic activities and they assure ambient integrity in tropical coastal areas. Due to wealth of available organic substance, a great variety of vegetal and animal beings will go to use it: hundreds of different types of very small beings, called plncton. The vegetal fraction of plncton, called fitoplncton, removes leaves them nutrients the water and, through the photosyntheses, it grows and if it multiplies.
