1. Application of Markov chains to Standardized Precipitation Index (SPI) in São Francisco River Basin
Resumo Este trabalho objetivou avaliar períodos secos e chuvosos nas sub-regiões da Bacia Hidrográfica do Rio São Francisco (BHSF) utilizando o Índice de Precipitação Padronizado (SPI) e cadeias de Markov. Cada sub-região da BHSF possui características físicas e climáticas específicas, dessa forma foram utilizadas quatro estações pluviométrica

2. Morfodinâmica da embocadura da Lagoa do Peixe e da linha de praia adjacente
The investigation of morphological change in lagoonal inlets and shorelines can be instrumental to describe the influence of short term coastal processes. The Lagoa do Peixe (LP) is set within the Parque Nacional da Lagoa do Peixe (PNLP), 344 km², located on the mid-section of the Rio Grande do Sul coastal plain. The objective of this work was to describe t

3. Eventos extremos de precipitação no leste da Amazônia. / Extreme events of rainfall in Eastern Amazon.
The aim of this study was to characterize the extreme events of rainfall in Eastern Amazon, to analyze on ocean-atmosphere conditions in global scale associated with intense occurrence periods of these events, to contribute for temporal variation comprehension of rainfall extreme events, as well as of determinant phenomena to its occurrence and to make furth

4. Identificação da ocorrência em Bagé (RS) entre 1961 – 2009
As estiagens fazem parte da história do clima do Rio Grande do Sul (RS) e a frequência desse fenômeno não é baixa. O desenvolvimento socioeconômico de uma região pode ser afetado pela falta dos recursos hídricos necessários para as atividades como a agrícolas e uso doméstico. Estudos climáticos têm buscado compreender a dinâmica da distribuiç�

5. Variabilidade de precipitação em Taubaté, Vale do Paraíba, SP / The variability of the precipitacion in Taubaté, Vale do Paraíba, SP
It is a known fact that the process of nature transformation became faster from the second half of the eighteenth century, with the industrial revolution, marked by the use of steam machinery. The process of urbanization triggered by industrialization caused a negative impact to the environment and climate changes. This work aims to relate changes in climati

7. Nitrogen losses by emissions of nitrous oxide (N2O) and its relation with litterfall and fine root dynamics in the Atlantic Forest, Brazil / Perdas de nitrogênio pela emissão de óxido nitroso (N2O) e sua relação com a decomposição da serapilheira e biomassa de raízes na floresta de Mata Atlântica
Soils of tropical ecosystems are considered one of the major natural sources of nitrous oxide (N2O) to the atmosphere. Most of the N2O in soils is produced by two microbial processes, denitrification and nitrification. Litterfall and fine root dynamics are believed to contribute to the labile carbon (C) and nitrogen (N) and also contribute to the production

8. O uso de ferramentas fractais e redes complexas no estudo da variabilidade pluviomÂetrica do Nordeste do Brasil
Brazil Northeastâs climate is usually described as semi-arid, characterized by hard dry seasons intermingled by hard rainfall seasons. Some areas of Northeast present annual pluviometric measure about 400 mm in mean, while in others the annual pluviometric measure is about 2000 mm. Rain events result from interplay of several physical phenomena, most of whi

9. Análise da variabilidade de indicadores climáticos para a precipitação pluvial no Rio Grande do Sul / Climate indicators of variability analysis to pluvial precipitation in Rio Grande do Sul
Foram calculados dez índices de freqüência e de intensidade da precipitação pluvial a partir de dados dessa variável, de treze estações meteorológicas bem distribuídas no Rio Grande do Sul, para os meses da primavera e verão, entre 1961 e 2005. Através de um modelo de regressão linear simples foram determinadas as tendências desses índices e f

10. RESPOSTAS ECOFISIOLÓGICAS E BIOQUÍMICAS DO Ocimum basilicum L. CULTIVADO EM DIFERENTES NÍVEIS HÍDRICOS / Reposts ecophysiological and biochemical of the Ocimum Basilicum cultivate under water deficit.
The sustainable development of northern agroecosystems requires, among other factors, the use of species adapted to region the edafoclimtic conditions. Plants able to support water deficits are more indicated, considering to no regular distribution of pluviometric precipitation the high evapotranspiration are characteristic northest region of Brazil.

11. Avaliação de genótipos de arroz de terras altas na Zona da Mata de Pernambuco.
Rice (Oryza sativa L.) is one of the most cultivated and consumed crop in all continents. In Brazil, it is one of the basic sources of food, but the Brazilian productivity average is considerad low. That is due to inappropriate cultivation practices in some regions and mainly because there is not a sufficient number of evaluated and recommended cultivars for

12. Estádios larvais e ocorrência saxonal de imaturos de Psaroniocompsa incrustata (Lutz,1910)(Diptera:Smimuliidae) no Rio Pium, município de Nísia Floesta, RN
The larval instars, seasonal occurrence and environmental factors influence on Psaroniocompsa incrustata (Lutz, 1910) (Diptera: Simuliidae) immature were studied according to its physical and chemical aspects of breeding water. Four collects were made at vegetal substrate from margin, middle and floating on the Pium river, city of Nísia Floresta, state of R
