13. Behavior of rubber tree clones to the South American Leaf Blight (SALB) and potential impact of global climatic changes on the disease occurrence / Comportamento de clones de seringueira ao mal das folhas e potencial impacto das mudanças climáticas globais na ocorrência da doença
The unsuccessfulness of the natural rubber cultivation (Hevea spp.) on the cultivation areas in Brazil is due, mostly, to the occurrence of the rubber tree South American Leaf Blight (SALB), caused by the fungus Microcyclus ulei (P.Henn. v. Arx.). The strategies of the disease management are based on the genetic resistance of plants to the SALB, on the pheno

14. Climatic changes: what if the global increase of CO2 emissions cannot be kept under control?
Climatic changes threaten the planet. Most articles related to the subject present estimates of the disasters expected to occur, but few have proposed ways to deal with the impending menaces. One such threat is the global warming caused by the continuous increase in CO2 emissions leading to rising ocean levels due to the increasing temperatures of the polar

15. Leituras, limites e possibilidades de gráficos do ENEM no contexto do aquecimento global e das mudanças climáticas / Readings, limits and possibilities of ENEM graphs in the context of global warming and climate change
This research sought to understand how among issues of ENEM, graphs in the context of global warming and climate change, regardless of the focus in discussion, contribute to the significance of the issues and even for the same context, and what are the basic characteristics of the reader of the graphs that questions presume. To this end, a clip was made that

16. Um novo horizonte de correlação para o triássico superior do Rio Grande do Sul
A new biozone - called Ictidosaur Assemblage Zone - is proposed to the Upper Triassic Caturrita Formation from Southern Brazil, based on the discovery of a distinct tetrapod association characterized by the presence of little non-mammalian cinodonts including Riograndia guaibensis, Brasilodon quadrangularis and Brasilitherium riograndensis. Besides, the adva

17. Global climatic changes, a cse study of air temperature variation and its impacts in the municipal district of Ubatuba, north coasth of São Paulo / Mudanças climáticas globais, um estudo de caso da variação da temperatura do ar e seus impactos no município de Ubatuba, litoral Norte de São Paulo
This work aims to provide a forecast of the air temperature for future climatic scenarios with an estimation of sea level rise and its environmental consequences in the municipality of Ubatuba. The adopted methodology is based on the use of air temperature simulated data from HadCM3 Model from Hadley Center from United Kingdom (from 2000 until 2099) consider

18. Sustainable business: the concept of governance change - application a company in the petrochemical / Sustentabilidade empresarial: o conceito da governança climática aplicação a uma empresa do ramo de petroquímica
With vital significance, the greenhouse effect gases (GEG), as carbon dioxide and methane, among others, retain sun heat in the atmosphere. This fact avoids sun radiation from dissipating, without letting the Planet being warm enough to keep right conditions for live existence of Earth. However, mankind activities are increasing concentration of these gases

19. Uso de um modelo regional de clima-vegetação para estimativa dos componentes da evapotranspiração sob condições climáticas atuais e futuras de aquecimento global / Use of a regional model of climate-vegetation for estimate of components of the reference evapotranspiration under current and future climatic conditions of global warming
O objetivo do presente estudo foi analisar a distribuição espacial dos componentes da evapotranspiração de referência (ETo) no Brasil e posteriormente a variabilidade temporal por meio da técnica da análise harmônica, sendo para isso foi feito inicialmente uma análise de variância, fase e amplitude para o tempo presente (1980-2000) e, posteriorment

20. Paradigms for the maritime works project in the context of climate change. / Paradigmas para os projetos de obras marítimas no contexto das mudanças climáticas.
Global warming and the consequent increase of the mean sea level rise will be a challenge to the maintenance and development of offshore structures in the coming decades. Both global climate change and the fact that the extreme storms are experiencing substantial changes have profound consequences for the society and the environment. The study aimed to prese

21. Analise espaço-temporal das condições meteorologicas e incidencia de gripe e pneumonia no municipio de São Paulo / Temporal-spatial analysis of the relationships between meteorological data and incindence of the influenza (flu) and pneumonia in the São Paulo metropolis
Everywhere in the world, the popular culture associates the alterations in meteorological data - rain, wind, temperature, humidity - with the behavior of human health. Scientific studies have been conducted in the aim to relate the meteorology and climate to the occurrence of human diseases, specifically of the circulatory and respiratory systems. The Sao Pa

22. Análise de imagens do satélite ALOS PALSAR (Banda L, modo polarimétrico) para discriminação de coberturas de terras no Distrito Federal
Land cover maps are important source of data for environmental monitoring, biodiversity conservation, social, economic and environmental zonning, and local and global climatic changes, among other activities. In the Federal District of Brazil (FD), land cover mappings have been obtained from optical images. However, radar data are valuable alternative for th

23. Macroecology of the genus Uca (Crustacea, Decapoda): patterns of diversity, distribution and responses to global climate change / Macroecologia do gênero Uca (Crustacea, Decapoda): padrões de diversidade, distribuição e respostas às mudanças climáticas globais
Macroecology of the genus Uca (Crustacea, Decapoda): Patterns of diversity, distribution and responses to global change. The genus Uca, composed by 97 species, has a worldwide distribution on coastal marine regions, mainly in tropical environments. Many researches have used the genus Uca as a model of study, although the actual scientific knowledge about thi

24. Interdecadal variability of precipitation in the Western Brazilian Amazon / Variabilidade interdecadal da precipitação na Amazonia Ocidental brasileira.
The present work focused on the interdecadal variability of precipitation in the Western Brazilian Amazon in order to help improve this knowledge and, in addition, to analyze, study and evaluate the low-frequency variability of the hydrological cycle in this region. To this end, we used data collected from conventional rain gauge stations 5, available at the
