13. Variabilidade do ambiente térmico em galpão para frangos de corte e sua influência nas respostas fisiológicas e comportamento das aves / Variability of thermal environment in barn for broilers and its influence on physiological responses and behavior or birds
The experiment was conducted in a barn with 21,000 Cobb male broilers, in order to characterize the variability of the thermal environment in a broiler barn and verify if the physiological responses and behavior are influenced by it. The treatments consisted of five 25 m-long sections (S1, S2, S3, S4 and S5) along the hall, set in ascending order from the ai

14. Avaliação do impacto da variabilidade/mudanças climáticas sobre Euschistus heros, Telenomus podisi e ferrugem asiática na soja, no Região Sul do Brasil / Risk assessment of variability/climate change on the Euschistus heros, Telenomus podisi and asian soybean rust of soybean, in the southern region of Brazil
Brazil is the second largest soybean producer, however, biotic and abiotic factors affect the crop, causing serious damage, with significant economic impact. Among these problems, Euschistus heros and asian soybean rust. For biological control of the insects, the parasitoid Telenomus podisi has been described as one of the potential agents in MIP programs. T

15. Precipitação pluvial e temperatura do ar no Estado de São Paulo: periodicidades, probabilidades associadas, tendências e variações climáticas / Rainfall and air temperature series of the State of São Paulo, Brazil: periodicities, associated probabilities, trends, and climate variations
The socio-economic relevance of São Paulo State agribusiness, and the vulnerability of agriculture atmospheric events indicate the need for constant study of the dynamics of the climate system of the State of São Paulo, Brazil. The propose of this work was to study the statistics of time series of rainfall (PRE), maximum air temperature (Tmax), and minimum

16. Variabilidade subinercial das correntes na plataforma continental ao largo de Cabo Frio (RJ): observações / Subtidal variability of the currents on the continental shelf off Cabo Frio (RJ): observations
This work was developed within the context of the continental shelf hydrodynamics, with the aim of studying the subtidal variability of the currents in the far north of the South Brazil Bight (SBB). The area of the study is located in the vicinity of Cabo Frio (RJ) and Arraial do Cabo (RJ) (approximately 23º S / 42º W). Despite being a well known and studi

17. Storm-track na América do Sul e vizinhanças: climatologia, variabilidade e mudanças climáticas / Storm-tracks over South America and adjacent areas: climatology, variability and climate change
This study deals with an extratropical cyclone climatology for South America (SA), Antarctic Peninsula and adjacents oceans in the austral winter and summer seasons for the current and future climate. An automatic and objective method to monitoring specific features of meteorological fields of the "European Centre for Medium Range Weather Forecast"(ECMWF) an

18. Características da precipitação pluviométrica do nordeste brasileiro e seus padrões de acoplamento com as TSM do Pacífico Equatorial e Atlântico Sul. / Rainfall characteristics in northeastern brazil and their patterns coupling with sst equatorial Pacific and South Atlantic.
The eastern coast of the Northeast Brazil (NEB) is a region where transient weather systems interact with local systems, modulating their frequency and intensity. Understanding the mechanisms of such interactions may be instrumental in explaining the observed precipitation patterns in this region. The objective of this work is quite within this scope and tak

19. Relation between the Antarctic Sea ice concentration and low temperatures in South America / Relação entre a concentração de gelo marinho Antártico e a temperatura mínima na América do Sul
The Antarctic Sea Ice Concentration (ASIC) is thought to be an important element in the analysis of the world climate. However, few studies have investigated its relation to other climatic elements. Thus, the aim of this study was to verify the relation between the ASIC and low temperatures in South America through two approaches. The first, regional, invest

20. Space-temporal behavior of rainfall in Southern Brazil using TRMM and SRTM data / Comportamento espaço-temporal da precipitação na Região Sul do Brasil utilizando dados TRMM e SRTM
This work investigates the space-temporal behavior of rainfall in Southern Brazil during the 1988 and 2007 period. The evaluation was based on three features: 1) climatological aspects, 2) geographic trends from relief features, and 3) main variability modes. Two complementary data sets of rainfall were used: rain gauges and rainfall estimates from the Tropi

21. Temporal and spatial variability of rainfall and water balance in the state of Rondônia, Brazil: characterization tendency analysis / Variabilidade temporal e espacial das chuvas e do balanço hídrico no estado de Rondônia: caracterização e análise de tendência
Amazon deforestation rate has been significant, resulting in a great concern about the effect that the reduction of the forest can have on the climatic dynamics in this region, as well as in other brazilian locations. In such context, the present work aimed to verify if the current rate of deforestation in Rondônia, last 30 years has been contributed for ch

22. Sugarcane crop efficiency in the State of São Paulo between growing seasons of 1990/1991 and 2005/2006. / Eficiência da produção agrícola de cana-de-açúcar no Estado de São Paulo entre as safras 1990/1991 e 2005/2006
The sugarcane is an important resource for food and energy production with scale to help the economy of fossil fuels and the development of new guidelines for socio-economic development in sustainable basis. The State of São Paulo is a region of great potential to meet the sugarcane demand in terms of sugar, ethanol and energy, since it has a long tradition

23. Conidia aerobiology and cercosporiosis management of soybean (Glycine max) / Aerobiologia de conídios e manejo das cercosporioses da soja (Glycine max)
The cercospora leaf blight and the frogeye leaf spot are two important diseases of soybean culture. Due to the high variability of both pathogens, the search for new sources of resistance and for efficient control methods is necessary. Therefore, this work, divided into five chapters, had as general objectives: (a) the evaluation of soybean genotypes reactio

24. Distribuição geográfica da Sigatoka Negra da bananeira estimada por modelos de mudanças climáticas globais
Global climatic changes will potentially influence plant diseases and the efficacy of their management options. One of the most likely impacts of climate change will be felt by the geographical distribution of plant diseases. Black Sigatoka is considered the most damaging and costly disease of banana. The socio-economic impact of this disease has continued t
