1. Assessment of the dendrochronological potential of Licaria bahiana Kurz, an endemic laurel of lowland Atlantic forests in Brazil
ABSTRACT The Atlantic Forest of southeastern Brazil has been considered to have the highest number of tree species per hectare in the world. Assessing the influence of climate on tropical tree species is a priority in the face of ongoing climate change, and for which dendrochronological studies have been important. We address the dendrochronological potentia

2. Stability of Soil Moisture Patterns Retrieved at Different Temporal Resolutions in a Tropical Watershed
ABSTRACT Above and underground hydrological processes depend on soil moisture (SM) variability, driven by different environmental factors that seldom are well-monitored, leading to a misunderstanding of soil water temporal patterns. This study investigated the stability of the SM temporal dynamics to different monitoring temporal resolutions around the borde

3. Time-space characterization of droughts in the São Francisco river catchment using the Standard Precipitation Index and continuous wavelet transform
RESUMO Este artigo enfatiza a caracterização espaço-temporal de secas na bacia do rio São Francisco, com base na análise de ondaletas de séries temporais do Índice Padronizado de Precipitação (SPI). Para melhorar a estimação do SPI, os procedimentos para análise regional por momentos-L foram empregados na delimitação de regiões estatisticament

4. Construção e aplicação de um índice de vulnerabilidade humana à mudança do clima para o contexto brasileiro: a experiência do estado do Espírito Santo1
Resumo A mudança do clima representa séria ameaça para a população humana, causando impactos em diferentes setores. Conhecer os fatores que elevam a vulnerabilidade do ser humano à mudança do clima permite identificar pontos críticos e direcionar ações imediatas para reduzi-la. Assim, este estudo desenvolveu e aplicou um índice de vulnerabilidade

5. HOW STRONG IS THE RELATIONSHIP BETWEEN RAINFALL VARIABILITY AND CAATINGA PRODUCTIVITY? A CASE STUDY UNDER A CHANGING CLIMATE
ABSTRACT Despite the knowledge of the influence of rainfall on vegetation dynamics in semiarid tropical Brazil, few studies address and explore quantitatively the various aspects of this relationship. Moreover, Northeast Brazil is expected to have its rainfall reduced by as much as 60% until the end of the 21st Century, under scenario AII of the IPCC Report

6. Estabilidad de la estimación de la onda anual en escala diaria de la temperatura
The choice of estimation of deterministic effect method in climate series is usually the starting point for most studies on climate variability. This decision is more sensitive when the presence of nonlinear phenomena is explored. Therefore, this paper analyzes the robustness and stability of different methods to estimate the annual cycle in time series of d

7. Some aspects of chicken behavior and welfare
Brazil is the world leader in broiler production and export. It achieved this position mainly to its excellent supply chain structure and climate, which favor poultry and grain production throughout its territory. Although Brazilian egg production is not as important as broiler production, this segment presents great potential of increasing its share in the

8. Contribuição dos Distúrbios Ondulatórios de Leste para a chuva no Leste do Nordeste do Brasil: evolução sinótica média e simulações numéricas / Easterly Waves contribution for the eastern Northeast Brazil precipitation: mean synoptic evolution and numerical simulations
This study purpose was to verify the contribution of Easterly Wave Disturbances (EWDs) in the observed precipitation over the eastern part of Northeast Brazil (ENEB) during rainy season (AMJJ) and evaluate seasonal rainfall forecasts from RegCM3 (Regional Climate Model version 3). For the EWDs subjective identification it was used infrared satellite images a

9. A Influência do El Niño e La Niña nos depósitos lamíticos e na dispersão sedimentar na Praia do Cassino e na desembocadura da Lagoa dos Patos, Rio Grande, RS-Brasil
A Praia do Cassino, localizada no sul do Brasil, é freqüentemente coberta por extensivos depósitos de lama, ocasionando importantes efeitos de curta e longa duração. Alterações no volume das precipitações interferem diretamente no escoamento fluvial e, conseqüentemente, no volume de sedimentos que aportam na Lagoa dos Patos. Dados do regime de prec

10. Atmospheric patterns associated with concentrations of tropospheric ozone in the metropolitan region of Sao Paulo / Padrões atmofésricos associados a concentrações de ozônio troposférico na região metropolitana de São Paulo
In the past few years, tropospheric ozone has been noticed to exceed the states environmental agency (CETESB) air quality standards more than any other air pollutant in the Sao Paulo Metropolitan Area (SPMA), Brazil. Its assumed that different atmospheric patterns are responsible for different impacts on ozone concentrations, due to already known phenomena c

11. Consequências climáticas da desertificação parcial do semi-árido do nordeste brasileiro / Climatic consequences of gradual desertification of the semi-arid region of northeast Brazil
The climatic impacts of partial desertification in the Semi-arid region of Northeast Brazil (SANEB) are evaluated by regional model (MM5) simulations. Maps of natural vegetation (without human influence; SANEB covered predominantly by dry shrubland known as caatinga), total desertification (replacement of the natural vegetation by desert in SANEB), partial d

12. Measures of the interannual marine variability on southeast Brazilian bight and its relationship to the spawning areas of Brazilian sardine (Sardinella braziliensis) / Medidas da variabilidade interanual marinha sobre a plataforma continental sudeste do Brasil e sua relação com áreas de desova da sardinha-verdadeira (sardinella brasiliensis)
This work aims to investigate the relation of marine interannual variability in a region located in southern coast of Brazil, also known as the Southeast Brazilian Bight (SBB) and the spawning areas of the Brazilian sardine (Sardinella braziliensis) in SBB. SBB marine ecosystems are related to a strong influence of a coastal upwelling system. Variables used
