| O objetivo desse trabalho foi avaliar a regeneração natural e a abundância de espécies exóticas no sub-bosque de um plantio experimental de Araucaria angustifolia, em Viçosa, MG. A amostra correspondeu a 40 parcelas de 2 m x 2 m, onde mediu-se o diâmetro ao nível do solo (DNS) de todos os indivíduos arbustivo-arbóreos com diâmetro ≤ a 5,0 cm e altura ≥ a 0,5 m. Foram calculados os parâmetros fitossociológicos e os índices de diversidade e equabilidade. As espécies foram classificadas quanto à forma de vida, classe sucessional e síndrome de dispersão. Foram amostrados 980 indivíduos, sendo observada maior proporção de espécies arbustivas, típicas de sub-bosque e zoocóricas. A espécie exótica Archontophoenix cunninghamiana, conhecida como palmeira... |

| The objective of this study was to evaluate the natural regeneration, to characterize the syndromes of seed dispersal and successional classes, and the parameters of relative humidity, temperature and luminosity of a restored forest through planting, with 40 years old, in Viçosa, MG, Brazil. It was registered 33 families, 102 species plus one morphotype (vines) and 1,938 individuals, with high diversity (H '= 3.56) and low ecological dominance (J' = 0.77), higher percentage of early secondary successional category, at the species level (33.3%), and late secondary, level of individuals (37%) and predominance of the zoochorous dispersion. The layer of forest regeneration restored reached similar parameters to those found in natural semideciduous forests in... |

| With the objective to evaluate the soil seed bank of four distinct areas undergoing restoration activities of different intensities 30 samples of topsoil from 30 x 25 x 7.0 cm in deep were collected in each area and transported to greenhouse at 25 °C and relative humidity around 70%. The emerging seedlings were counted every two weeks for one year. Shannon diversity and Pielou evenness were calculate. The species were classified according to dispersal syndrome, life form and successional class. Considering the four areas, 323 individuals m-², emerged on average, belonging to 26 families and 69 species. Approximately 31% of the sampled individuals were Setaria vulpiseta, and it was present in all four areas. Areas 1 and 2 have low diversity and low... |
