1. Soil-vegetation relationships and community structure in a "terra-firme"-white-sand vegetation gradient in Viruá National Park, northern Amazon, Brazil
ABSTRACT Viruá National Park encompasses a vast and complex system of hydromorphic sandy soils covered largely by the white sand vegetation ("Campinarana") ecosystem. The purpose of this study was to investigate a vegetation gradient of "terra-firme"-white sand vegetation at the Viruá National Park. Nine plots representing three physiognomic units were ins

2. Island effect on diversity, abundance and vegetation structure in the Chocó Region
The aim of this study was to evaluate the effect of island area and isolation on species richness and abundance, and vegetation structure of Isla Palma by comparing these parameters with those of the continental location, Playa Chucheros. By sampling vegetation at each locality using Gentry transects (10 50x2 m) we found 204 species of plants at Playa Chuche

3. Floristic and phytogeographic pattern of native field in southeastern Brazil
The waterlogging of soils creates selective environments for plant species. The frequency and duration of flooding influence the responses to ecological processes, determining the structure and floristic composition of vegetation formations. We investigated the relationship between floristic composition and environmental heterogeneity of native field, one ph

4. Fitossociologia de um fragmento florestal com monodominÃncia de Euterpe edulis Mart / Phytosociology of a forest patch with monodominance of Euterpe edulis Mart
The objective of this work was evaluating the structure of the shrub component of a forest patch with a monodominance of Euterpe edulis Mart. and identifying floristic groups by means of statistical multivariate techniques. Situated in the town of Inconfidentes in Minas Gerais State, for the study in a systematic form, 29 plots of 400 m2 distributed into six

5. Structure of the tree community in stands of Araucaria forests, in São Paulo state, Brazil / Estrutura da comunidade arbórea de trechos de florestas de Araucaria no estado de São Paulo, Brasil
The Ombrophilous Mixed Forest covered an ample area in the South and in part of the Southeast of Brazil. Since the 2Oth century, the increase of anthropic intervention has put the ecosystem in a critically threatened category and the Araucaria angustifolia (Bert.) O. Kuntze, the typical species of this ecosystem, in extinction prone. The goal of the present

6. Composição florística e estrutura da comunidade arbórea em duas áreas do cerrado Sensu stricto, em Uberlândia - Minas Gerais / Floristic composition and structure of tree community in two areas of cerrado sensu stricto in the Uberlândia, Minas Gerais
The cerrado covers about 23% of the Brazilian territory, and 70% of the cerrado area is stricto sensu physiognomy. To promote a better understanding of its physiognomic the cerrado study is of vital importance. With the objective to analyze and to compare two tree area of cerrado sensu stricto (brazilians savanna) in the Reserva Ecológica do Clube Caça e P

8. VariaÃÃes florÃsticas e estruturais em um fragmento de floresta paludosa no Alto Rio Pardo em Santa Rita de Caldas, MG. / Floristics and structural variations in a fragment of swamp forest from the high Rio Pardo River in Santa Rita de Caldas, MG.
A survey of the tree community of a swamp semidecidual Montana forest, situated in Santa Rita de Caldas, MG at the Upper Rio Pardo river (1156-1203 m of altitude, 22o 05â 44â S; 46o 21â 20â W) was accomplished with the purpose of assessing its environment and structural variation. The physiognomic (density, basal area and distribution of size of the tree

9. Floristica, Fitossociologia e Heterogeneidade em um povoamento com predominÃncia de Anadenanthera peregrina (Benth.)Speg. / FLORÃSTICS, PHYTOSOCIOLOGY AND HETEROGENEITY IN A STAND WITH PREDOMINANCE OF Anadenanthera peregrina (Benth.) Speg
The present study was developed in an ancient abandoned area of planting of Anadenanthera peregrina, on the campus of the Federal University of Lavras, MG of about 7,56ha. It was aimed to report the floristic composition of this area as well as its phytosociological structure, paying attention to the ecologic aspects of the species, as the regeneration, disp

Sensoriamento remoto e sistemas de informação geográfica como subsídio para levantamentos fisionômico - estruturais em floresta tropical úmida - estudo de caso: Estação Científica Ferreira Penna, PA / Remote sensing and geographic information system to study physiognomic and structural features in tropical rainforest - case study at Estação Científica Ferreira Penna (Pará state Brazil)
Recently a scientific station, Ferreira Penna, was set in the Caxiuanã National Forest (Pará State) giving to the Museu Paraense Emílio Goeldi the opportunity to start several scientific projects on techniques for forest management and biodiversity preservation. The present study was designed to contribute to a better definition of representative sampling
