1. Temporal changes in species composition, diversity, and woody vegetation structure of savannas in the Cerrado-Amazon transition zone
ABSTRACT Vegetation in the transition between tropical forest and savanna is hyperdynamic and there is evidence that in the absence of fire, forest advances over savanna. Between 2008 and 2013 we evaluated changes in species composition and diversity and in the structure of the woody vegetation of savanna physiognomies in the transition between the Cerrado a

2. Contributions of the complexity paradigm to the understanding of Cerrado's organization and dynamics
ABSTRACT The Brazilian Cerrado is a vegetation mosaic composed of different physiognomies. Discussions remain open regarding the factors and processes responsible for the dynamic and spatial organization of the Cerrado - in its different physiognomies. The contributions of the complexity paradigm in this context are still less exploited, despite its great po

3. Heterogeneity of bird communities in a mosaic of habitats on a restinga ecosystem in southeast Brazil
ABSTRACT Restinga occurs as a narrow band of coastal habitats throughout the Atlantic Forest, although it presents considerable variation in vegetation structure, which likely contributes to heterogeneity in species inhabiting this endangered ecosystem. The goal of this study is to examine how variation in vegetation and abiotic conditions in the restinga ec

4. The Dynamic of some Biochemical Indicators at Species of Medicinal Plants from Areas of Suceava County, Romania, Emerged under the Mining Pollution Influence
ABSTRACT It is known the fact that the mining causes huge damages on the environment having negative biologic effects extremely severe on some groups of organisms of the food chain. The pollutants causes major damages at the level of leaves' cuticles, the vegetation reacting through irreversible modifications at the tissue's level and at substances and energ

5. Geotechnology application for data acquisition for agricultural and environmental management of the municipality of Vitória Brazil-SP
ABSTRACT The present study aimed at associating geoprocessing procedures for analysis of land use and native vegetation for municipal management, using an easy access and low cost methodology to the public administration of the municipality of Vitória Brazil/SP. Initially, the land use and the land occupation were evaluated, being delimited the municipal hy

6. Structure of Humic Substances from Some Regions of the Amazon Assessed Coupling 3D Fluorescence Spectroscopy and CP/PARAFAC
The Amazon rainforest presents one of the greater biodiversity in the world and a huge and dynamic carbon reservoir, both in the vegetation and in the soil pools, so it is an attractive subject of study. In the present paper, humic acids from a toposequence of an Oxisol-Spodosol system associated with kaolin was studied using fluorescence emission-excitation

7. Spatial and temporal dynamics of drosophilid larval assemblages associated to fruits
The study of organisms and their resources is critical to further understanding population dynamics in space and time. Although drosophilids have been widely used as biological models, their relationship with breeding and feeding sites has received little attention. Here, we investigate drosophilids breeding in fruits in the Brazilian Savanna, in two contras

8. COMPORTAMENTO DE TALUDE DA MARGEM DO RIO SÃO FRANCISCO SUBMETIDO À TECNICA DE BIOENGENHARIA DE SOLOS. / BEHAVIOR OF THE SLOPE OF THE SÃO FRANCISCO RIVER SUBJECTED TO THE SOIL BIOENGINEERING TECHNIQUE.
The lower San Francisco river had changed their hidrossedimentological behavior by changes in river channel through the impoundment of water reservoirs for the implementation of large hydropower projects. These direct impact on the stability of river banks, demands actions to mitigate the erosion resulting from soil mass movements. Soil bioengineering, which

9. Matéria orgânica e atributos químicos em solo de tabuleiros costeiros sob diferentes coberturas vegetais / Organic matter and chemical attributes of an Coastal Tableland soil under different vegetation covers
The conversion of native vegetation in agricultural and forest crops results in changes in soil properties. The aimed was to assess the dynamic attributes of a Yellow Oxisol under differents vegetation covers in the Coastal Tableland. Soil samples were collected at depths of 0-10, 10-20 and 20-40 cm in June 2011 in Sooretama, ES, considering four soil vegeta

10. Dinâmica estrutural e reprodutiva da vegetação lenhosa de uma floresta paludosa em Bauru/SP / Reproductive and structural dynamic of woody vegetation in a swamp forest in Bauru/SP
Estudos sobre a dinâmica de comunidades florestais que avaliam a interação de fatores bióticos e abióticos num determinado intervalo de tempo, expresso pelas diferenças nos valores de mortalidade, recrutamento e crescimento dos indivíduos amostrados, podem fornecer informações sobre a estrutura, mudanças temporais e espaciais, além de fornecer inf

11. Um problema de interação oceano-atmosfera-biosfera: alterações potenciais na vegetação da América do Sul devidas ao aquecimento global
One of the expected consequences of global warming is change in the distribution and structure of vegetation. Few studies have evaluated the dynamic behavior of tropical vegetation against a backdrop of elevated CO2, with mixed results for the vegetation in South America. One possibility to explain the opposite results are different patterns of sea surface t

12. UTILIZAÇÃO DE MODELO MATEMÁTICO NA BUSCA DO MANEJO SUSTENTÁVEL DAS PASTAGENS NATURAIS / USE OF MATHEMATICAL MODEL IN THE SEARCH OF SUSTAINABLE MANAGEMENT OF NATURAL GRASSLANDS
O objetivo deste trabalho foi modelar em uma escala espaço-temporal a dinâmica vegetacional de pastagens naturais caracterizada por tipos funcionais quando submetidas a diferentes distúrbios, visando predizer padrões na vegetação de inventários futuros pela análise da dimensão fractal associada ao modelo de autômatos celulares. Assim, inicialmente
