Community structure and species composition of a periodically flooded Restinga forest in Caraguatatuba, São Paulo, Brazil Biota Neotropica
Pansonato,Marcelo Petratti; Lima,Renato Augusto Ferreira de; Oliveira,Alexandre Adalardo de; Bertoncello,Ricardo; Martini,Adriana Maria Zanforlin.
Abstract: The aim of this study was to characterize the structure and composition of the tree and shrub community in a 77-ha fragment of Restinga forest in Caraguatatuba, São Paulo, Brazil. In this fragment, forty 20 × 20-m plots (1.6 ha) were systematically allocated and all trees with a stem diameter at breast height (DBH) ≥4.8 cm were sampled. Sixteen plots were randomly chosen to also sample individuals with a DBH of between 1 and 4.8 cm. All individuals were tagged, identified to species level, and their diameters and heights were measured. A total of 2587 individuals (1616 ind./ha) from 119 species and 42 families were found with a DBH >4.8 cm, and 2659 individuals (4154 ind./ha) from 125 species and 38 families were found with a DBH >1 cm. The...

Community structure of vascular plants in treefall gaps and fire-disturbed habitats in the Atlantic rainforest, southern Bahia, Brazil Rev. Bras. Bot.
Martini,Adriana Maria Zanforlin; Santos,Flavio Antonio Maës dos; Prado,Paulo Inácio; Jardim,Jomar Gomes.
The effects of disturbances on plant community structure in tropical forests have been widely investigated. However, a majority of these studies examined only woody species, principally trees, whereas the effects of disturbances on the whole assemblage of vascular plants remain largely unexplored. At the present study, all vascular plants < 5m tall were surveyed in four habitats: natural treefall gaps, burned forest, and their adjacent understorey. The burned area differed from the other habitats in terms of species composition. However, species richness and plant density did not differ between burned area and the adjacent understorey, which is in accordance to the succession model that predict a rapid recovery of species richness, but with a different...

Structure, diversity, and spatial patterns in a permanent plot of a high Restinga forest in Southeastern Brazil Acta Botanica
Lima,Renato Augusto Ferreira de; Oliveira,Alexandre Adalardo de; Martini,Adriana Maria Zanforlin; Sampaio,Daniela; Souza,Vinícius Castro; Rodrigues,Ricardo Ribeiro.
We assessed the structure, diversity and distribution of tree species in a 10.24-ha permanent plot of high Restinga forest (HRF) in southeastern Brazil. We sampled 15,040 individuals belonging to 45 families, 87 genera and 116 species (density= 1,468 trees ha-1, and basal area= 28.0 m² ha-1). Mean richness was lower than other types of tropical forests and other HRFs that have been less intensively sampled, which is probably due to the younger age and hydromorphy of the soils in the study site. Tree density, basal area, species composition, and diversity all varied considerably depending on the size class considered. The studied plot had a density similar to other tropical forests but with a smaller basal area (fewer individuals > 60 cm in diameter),...
