Última Structure and floristic diversity of remnant semideciduous forest under varying levels of disturbance Acta Botanica Gris,Darlene; Temponi,Lívia Godinho; Damasceno Junior,Geraldo Alves. The perturbation of Neotropical forests generates large disturbances in biological communities. The species that suffer least from the resulting habitat fragmentation are the pioneers, because they possess greater ability to inhabit disturbed environments. Therefore, it is expected that species diversity will be greater in areas subjected to intermediate disturbance, such as the opening of gaps, because a large number of pioneer species will develop and coexist with species of more advanced successional stages. This study aimed to compare two forest remnants that differed in size and disturbance intensity, in order to determine the effects of disturbances on species diversity and the size ratios of individual trees. This was accomplished with comparative... Tipo: Info:eu-repo/semantics/article Palavras-chave: Intermediate disturbance; Species richness; Neotropical forest; Tree communities. Ano: 2014 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0102-33062014000400011 Influence of edaphic factors on the floristic composition of an area of cerradão in the Brazilian central-west Acta Botanica Bueno,Marcelo Leandro; Neves,Danilo Rafael Mesquita; Souza,Anderson Fernandes; Oliveira Junior,Elio; Damasceno Junior,Geraldo Alves; Pontara,Vanessa; Laura,Valdemir Antônio; Ratter,James Alexander. This study describes the influence of edaphic factors on the floristic composition of an area of cerradão (woodland savanna) in the city of Campo Grande, located in the Brazilian central-west. In 10 plots (5 × 20 m each), we evaluated all trees with a diameter at breast height > 4.77 cm. Soil samples were analyzed for each plot in order to determine edaphic variables correlated with species composition. We sampled 1180 individuals of 61 species. The evenness index was 0.74, which indicates uneven distribution of species, which was explained by a high abundance of Qualea parviflora, Curatella americana, Qualea grandiflora, Terminalia argentea and Astronium fraxinifolium. We registered more trees in the smallest diameter class and in the middle layer of...
