13. Productivity and crude protein concentration of Tifton 85 pasture-based mixed with pinto peanut
RESUMO Sistemas forrageiros constituídos pelo consórcio gramínea-leguminosa equilibram a oferta de forragem e minimizam impactos ambientais, pela redução da fertilização nitrogenada. O amendoim forrageiro tem várias características que são adequadas aos consórcios forrageiros, mas ainda não foram adequadamente explorados. O objetivo deste trabalh

14. Elevated atmospheric CO2 concentration improves water use efficiency and growth of a widespread Cerrado tree species even under soil water deficit
ABSTRACT Changes in atmospheric CO2 levels are accompanied by ecological interactions involving other environmental factors, such as drought, which can severely alter the water balance of plants, thereby influencing sap flow, gas exchange, and plant growth. The objective of this study was to evaluate the water use economy, leaf gas exchange, and growth of yo

16. Preprocessing procedures and supervised classification applied to a database of systematic soil survey
ABSTRACT: Data Mining techniques play an important role in the prediction of soil spatial distribution in systematic soil surveying, though existing methodologies still lack standardization and a full understanding of their capabilities. The aim of this work was to evaluate the performance of preprocessing procedures and supervised classification approaches

17. Effect of observed individual data of performance and excretion on life cycle assessment of piglets
ABSTRACT: The objective was to evaluate the impact of producing piglets fed diets with different crude protein (CP) levels through life cycle assessment and experimental data. In Trial I (performance), 28 crossbred barrow piglets, with an initial average weight of 15.3 ± 1.15 kg were divided into a randomized block design with four treatments, seven replica

18. Technical contributions to territorial planning and the use of ecosystemic services in a hydrographic basin with a water deficit in the Atlantic Rainforest of Brazil
Resumo A bacia do rio Dois Rios (R2R) (3.159 km²) recolhe os efeitos climáticos e ambientais típicos de zonas situadas a sotavento de cadeias montanhosas. Tem balanço hídrico deficitário, havendo poucos e específicos locais úmidos. Este estudo identifica, espacializa, caracteriza e agrupa as planícies de inundação com maior habilidade em produzir

19. Food web and ecological models used to assess aquatic ecosystems submitted to aquaculture activities
RESUMO: Ecossistemas aquáticos continentais desempenham papel fundamental no desenvolvimento econômico e social, entretanto, são vulneráveis à degradação ambiental devido às diversas pressões a que estão submetidos. Entre as principais atividades antrópicas a interferir nestes ambientes, podemos destacar a aquicultura. A modelagem matemática de

20. Dynamics of solar radiation and soybean yield in agroforestry systems
Abstract Soybean (Glycine max L.) monocropping have had a great socio-economic and environmental impact on the world and agroforestry systems has been considered an alternative for more sustainable production. The aim of this study was to evaluate the effect of different arrangements of agroforestry systems of the species E. urophylla x E. grandis and P. dub

21. The Brazilian Federal Government's Role in the Prioritization of EU Foreign Direct Investment and its Environmental Agenda
As a result of Foreign Direct Investment (FDI) from the European Union (EU), the environmental governance structure in Brazil has been challenged, bringing to light a legal ambiguity in the ecological obligations between the EU and Brazil. The article hypothesizes that this legal ambiguity is caused by the complex political and legal system that characterize

23. Do container size and predator presence affect Culex (Diptera: Culicidae) oviposition preferences?
ABSTRACT Organisms with complex life cycles typically do not exhibit parental care. Hence, the ability of adult females to choose quality oviposition sites is critical for offspring success. Gravid females of many insect taxa have the capability to detect environmental conditions in water-holding containers (e.g., resource level, presence of competitors or p

24. Population and development in the Amazon: A longitudinal study of migrant settlers in the Northern Ecuadorian Amazon
ABSTRACT This paper examines changes over time for a full generation of migrant settlers in the Northern Ecuadorian Amazon (NEA). Data were collected from a 2014 household survey covering a subsample of households surveyed previously in 1990 and 1999. We observed changes in demographic behavior, land use, forest cover, and living conditions. As the frontier
