Structure of adult trees and regeneration component of two mangrove forests of Parana/Estrutura do componente de regeneracao natural e arboreo de dois manguezais no estado do Parana

We analyzed the structures of two mangrove forests of Parana (Brazil) (Antonina Bay and Guaratuba Bay), considering adult trees and regeneration component. In each area, we marked three sub-areas and sampled five plots of 10 x 10 m, equivalent to 0.05 ha to adults trees and fifteen 1 x lm sub-plots...

Summary:We analyzed the structures of two mangrove forests of Parana (Brazil) (Antonina Bay and Guaratuba Bay), considering adult trees and regeneration component. In each area, we marked three sub-areas and sampled five plots of 10 x 10 m, equivalent to 0.05 ha to adults trees and fifteen 1 x lm sub-plots to assess the regeneration component. Avicennia schaneriana, Rhizophora mangle and Laguncularia racemosa exhibited distinct dominance and relative density between the areas. Mangroves of Antonina and Guaratuba differed both in the structure of natural regeneration as the tree component. The Principal Coordinates Analysis (PCoA) show that differences between areas in relation to abiotic variables of soil are strongly related to the structural parameters of trees. The different types of mangrove soil are the most significant factor in the differentiation between the mangrove areas since influences the salinity values and consequent adaptability of plants.
