| Understanding the plant communities affected by human activities related to urbanization is an important tool to conserve these. In this way, this study on an urban forest fragment aimed to evaluate, through a phytosociological study and investigation of the germination of the seed bank, the current forest structure, the successional strata, and the regenerative capacity of the remnant. Three different stages comprised this research, the first with a floristic survey of the entire forest remnant, then the phytosociological study of the canopy (PAP above 10 cm) and regeneration strata (PAP 5-10 cm), and at last, the study on the seed bank. The phytosociological survey of the canopy stratum presented 1,368 individuals, with 41 species distributed into 24... |

| This paper is a floristic and phytosociological study of the dry forest communities of the Dominican Republic. A total of 69 relevés in dry forest biotopes were carried out. The samples were subsequently subjected to Detrended Correspondence Analysis for the determination and study of possible groupings. The study does not cover tree formations growing on serpentines, nor the so-called semideciduous forests, peculiar to areas with higher rainfall. A total of nine phytocoenoses were identified. The most significant results led to the description of six new phytosociological associations: Simaroubetum berteroani(thorny dry forest on coastal dunes), Phyllostylo rhamnoidis-Prosopidetum juliflorae (southern Dominican disturbed dry forest), Consoleo... |

| The State of Rio de Janeiro still holds unknown portions of the Atlantic Forest, which represent gaps in the knowledge of this ecosystem. Paracambi and neighbor municipal districts comprise a vast stretch of virtually unknown forest that makes up part of the Serra do Mar biodiversity corridor. The following study describes the tree community structure in a stretch of the ombrophilous Atlantic Forest, in the Parque Natural Municipal do Curió (Curio MNP), Paracambi, Rio de Janeiro, which serves as the basis to evaluate species diversity and conservation status. The altitudes in the area ranges from 100 to 690 m and the climate varies from mild subtropical to tropical hot and humid. Forty plots (10x10m) were randomly placed along the area, where all the stems... |

| Phytosociological structure was studied in limestone mining quarries at Rio Claro, São Paulo, Brazil. Quarries presented a chronosequence, ranging 1 to 40 years old, with focus on vegetation community organization, floristic similarity and plant diversity of three areas in different successive stages, devastated by limestone mining. A total of 1957 individuals distributed in 32 botanical families and 91 species were sampled. Low species diversity was obtained, ranged among quarries ages. In the early-established quarries, Leguminosae, Malvaceae and Sterculiaceae were the families most representative in number of species, while for the age 27, Asteraceae and Poaceae were the most representative. Diversity indices indicated that species diversity changed... |

| The Baturité Mountain Range, located in the State of Ceará (BRA), displays on its highest levels a vegetation viewed as a disjunction from the Atlantic Forest in the East of Brazil. Among the various attributes associated with this vegetation, the abundance of water resources and a high biodiversity have a more outstanding relevance. However, in view of the current accelerated deforestation process, those attributes may be threatened in a near future. Therefore, the present work is a comparative study with its focus on vegetal community organization (tree sinusiae) and the floristic similarity and the phytodiversity of two areas in different successive stages, preserved and deforested 24 years ago. The aim of that intent was to obtain information that... |
