1. El Niño-Southern Oscillation impacts on grape yields in Santana do Livramento, Brazil: understanding and early warning of crop failure conditions
ABSTRACT El Niño-Southern Oscillation (ENSO) is an important source of year–to–year fluctuations in the whole global climate system and in the southern Brazilian climate. El Niño events affect this region, imposing unfavorable weather conditions (rainy/humid/overcast) during critical grapevine phenological stages, compromising yields in the current and

2. Estimation of Air Temperature Using Climate Factors in Brazilian Sugarcane Regions
Resumo Este estudo visava estimar as temperaturas mínimas e máximas mensais do ar nas regiões canavieiras do Brasil. Uma série histórica de 30 anos (1988-2018) de temperaturas máximas (Tmax) e mínimas (Tmin) do ar da plataforma da NASA/POWER foi utilizada para 62 locais que produzem cana-de-açúcar no Brasil. A regressão linear múltipla foi utiliza

3. AVALIAÇÃO QUÍMICA DE LENHOS CARBONIZADOS DE Araucaria columnaris SOB DIFERENTES CONCENTRAÇÕES DE OXIGÊNIO COMO COMPARATIVO DE ANÁLISE DE charcoal FÓSSIL
In the face of environmental changes concerns, the study of climate change becomes essential to understand the life trajectory of planet earth. For this purpose, this work seeks to understand climate change and fluctuations in the amount of atmospheric oxygen across geological ages, carbonizing the Araucaria columnaris wood in varying oxygen concentrations,

4. Incidence and spatial distribution of cases of dengue, from 2010 to 2019: an ecological study
ABSTRACT BACKGROUND: Dengue is an arbovirus that has caused serious problem in Brazil, putting the public health system under severe stress. Understanding its incidence and spatial distribution is essential for disease control and prevention. OBJECTIVE: To perform an analysis on dengue incidence and spatial distribution in a medium-sized, cool-climate and

5. The dark side of the rain: self-pollination setbacks due to water exposure in Pavonia varians Moric (Malvaceae), a species with rain-dependent flowering
ABSTRACT Plants that occur in arid or semi-arid environments may restrict their flowering to the rainy season to ensure water availability for reproductive functions. However, the exposure of flowers to rainfall can compromise their functionality, such as complex self-pollination mechanisms. We experimentally tested how rainfall exposure affects the sequence

6. INFLUENCE OF SOIL TEXTURE, CLIMATE AND VEGETATION COVER ON SECONDARY SOIL SALINIZATION IN PAMPAS PLAINS, SOUTH AMERICA
ABSTRACT Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. Secondary salinization was observed after afforestation at the Northern and Eastern subregions of the Río de la P

7. APLICAÇÃO DE NANOPARTÍCULAS DE FERRO ZERO-VALENTE (nFeZ) NA REMEDIAÇÃO DE SOLOS E ÁGUAS SUBTERRÂNEAS CONTAMINADAS: UMA REVISÃO
The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an im

8. Repeated geophysical measurements in dry and wet soil conditions to describe soil water content variability
ABSTRACT: There is an increasing interest in the application of geophysical surveys to assess the soil water content (SWC) variation in both spatial and temporal scales. In this work, a geophysical survey was carried out at an experimental farm in dry and wet conditions. We determined the SWC data measured with the gravimetric method, apparent electrical con

9. Longer crop cycle lengths could offset the negative effects of climate change on Brazilian maize
ABSTRACT Maize (Zea mays) is considered one of the most important crops for world food security. Globally, Brazil is the second largest maize producer and the fourth largest maize consumer. The climate variables is one of the main determining factors for crop yield. Given the possibility of future climate changes, our objective was to evaluate the impact of

10. Rootstock-scion interaction:6. Phenology, chilling and heat requirements of Cabernet Sauvignon grapevine
Resumo A fenologia da videira depende de vários fatores, como genética, características do solo, condições climáticas, pragas e doenças, e práticas culturais do vinhedo. Dentre estas, o porta-enxerto pode ter influência no comportamento da copa. Devido a isso, este experimento foi conduzido por dois anos para determinar o efeito do porta-enxerto na

11. Comparação entre variáveis microclimáticas de local aberto e florestal em um bioma da Mata Atlântica, sul do Brasil
Resumo Na região subtropical do Brasil, o ambiente é naturalmente caracterizado pelo clima quente e úmido. Essas condições são fatores preponderantes para a ocorrência da formação florestal na região, o bioma Mata Atlântica. Associa-se que qualquer condição diferente daquela que não seja natural, pode receber de forma diferenciada a condição

12. Climate Scale for Creativity in the Classroom: Evidence of Factorial Validity in the Portuguese Context
Resumo Habilidades criativas são um requisito para a atualidade e podem ser intencionalmente promovidas desde o início do percurso de vida. O ambiente escolar surge como privilegiado nessa promoção, sendo a facilitação de um clima criativo em sala de aula uma das formas de operacionalizá-la. Esse clima pode ser investigado sob a ótica dos alunos. O o
