RESUMO

The mangrove is defined as a coastal ecosystem of transition between terrestrial and marine environments and is characterized by salinized environment and the constant flooding caused by tides. With emphasis in the area of coastal systems Cananéia - Iguape, its importance is more related to the production of biomass, inserted in the natural bioenergy system, that increases the productivity of the coastal zone with the introduction of organic particles. Represent plant communities adapted to different physical conditions in coastal areas, including the weather. This study aimed to analyze the changes of the attributes climate (air temperature, relative humidity, solar radiation, wind and rainfall) in the mangrove at the barra of Ribeira-Iguape/SP, checking if the variation is related to the main characteristics of vegetation, more specifically with the presence of the canopy at the environment. Was installed a tower containing two microclimatic weather stations to obtain an analysis of changes in climatic attributes above and below the canopy of mangrove. It was also analyzed the structural characteristics of mangrove, aiming to compare with the attributes climate. This research contributed to understanding the variation on the attributes of climate and its influence in the mangrove vegetation. It was found that, on the scale of work microclimatic, the attributes of climate have a direct influence on the spatial distribution of vegetation. Furthermore, the characteristics of the canopy are the main control for this variation, mainly in distribution of rainfall below the canopy and the amount of solar radiation, which consequently influences the distribution of plant species of the environment.
