HANCORNIA SPECIOSA GOMES COLONIZATION IN RESTINGA ENVIRONMENTS IN TROPICAL CLIMATE AREAS

Abstract

The presence of Hancornia speciosa Gomes (mangabeira) in tropical climate areas is linked to the edaphoclimatic conditions demanded by this specie that is found in Brazil, spread from the state of Amapá to Espírito Santo. The general objective of this study was to discuss the colonization of Hancornia speciosa Gomes in restinga environments in tropical climate areas. It is an research is applied type research, with a qualitative-quantitative approach, emphasising procedures as bibliographical and documentary research, besides 49 technical visits in the spatial between the years of 2013 and 2019, that it was included Master's and Doctoral studies, funded by CAPES and CNPq. The adoption of a geographic concept of restinga allowed a better visualization and analysis of this environment, which presents the ideal soil and climate conditions for mangrove development, eventhough it has been threatened to the detriment, mainly, of urban sprawl. It is worth mentioning the proposal of classification of the restinga environments, once it allows a better biogeographic analysis of these transition environments in the Dunas - Restinga - Mata Atlântica trinomial. These three formation are considered as the ecological niche of mangabeira. Nowdays, restingas, despite the intense environmental vulnerability process that has transformed the natural environment into an anthropic and fragmented landscape, climatic and soil conditions still produce significant environmental conditions for the development of this specie. It is concluded that the colonization of populations of Hancornia speciosa Gomes in restingas is possible due to the abiotic, biotic factors and the evolutionary capacity of the species, represented by the dispersion.
