BIOGEOGRAFIA DOS MANGUEZAIS
Resumo
Os manguezais são ecossistemas localizados entre o mar e a terra
firme, ao longo de boa parte dos litorais tropicais e subtropicais de
todo o mundo. Este ecossistema, sujeito à influência de diversos fatores
geoecológicos, em especial à hidrodinâmica flúvio-marinha, possui uma
imensa importância para a biota de diversos ambientes, especialmente
para os organismos marinhos, que encontram nele abrigo, local para
reprodução, descanso e alimentação. Além da variada função ecológica, os
manguezais também são importantes para o próprio homem, fornecendo-o
recursos alimentares, madeira e proteção contra algumas catástrofes
naturais, como tsunamis. Por outro lado, os manguezais são destruídos no
mundo inteiro pela ação antrópica, que disputa com este ecossistema o
valorizado espaço costeiro. Sob esta perspectiva, este trabalho buscou,
através de uma revisão bibliográfica básica, trazer de maneira sucinta
algumas das características destes ecossistemas costeiros, através de um
enfoque biogeográfico e ecológico, bem como a sua importância
ecológica, benefícios que oferece ao homem e as ameaças deste aos
manguezais.

Biogeography of mangroves
Mangroves ecosystems are located between sea and land, along much of coastal tropical and subtropical regions around the world. This ecosystem, subject to the influence of several geoecological factors, the fluvial-marine hydrodinamic particularly, has an immense importance to the biota of the several environments, especially for marine organisms, which find him shelter for reproduction, rest and feeding. Besides the varied ecological function, mangroves are important also for man, providing food resources, wood and some protection against natural disasters, such as tsunamis. Furthermore, the mangroves are destroyed worldwide by human action, that this dispute with the valued ecosystem space on the coastal environment. From this perspective, this study searched, through of the basic review bring some of characteristics of the ecosystem, during a biogeographical and ecological focus as well as their ecological importance, benefits and offers to the man, and the human threats to mangroves.
