1. CROP MODELING WITH LESS DATA: THE FAO MODEL FOR SOYBEAN YIELD ESTIMATION
ABSTRACT Crop growth simulation models such as WOFOST and DSSAT are useful, but require several inputs that sometimes are not available, especially in developing areas. In addition, measured data is usually time and labor-intensive. In search of faster and easier methods for soybean estimates, this study presents a lower input requiring methodology for yield

2. CONTROLLED RELEASE FERTILIZER IN THE ROOTING AND PERFORMANCE OF CLONES OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native forest species of great economic and ecological interest, currently at risk of extinction. In addition to the difficulty of finding adult individuals of this species, plant production is limited, so the use of mini-cuttings can facilitate the spread of P. peroba. Thus, the objective of this study was to analyse the effe

4. 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

6. 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

7. HUNTING ACTIVITIES IN THE SEMIARID POTIGUAR UNDER THE STUDENTS PERSPECTIVE
Resumo Em áreas de Caatinga, a caça é considerada uma ameaça à fauna e ao equilíbrio ecológico, sendo o estudo da atividade cinegética relativamente importante para elaboração de estratégias de conservação. Baseado nesta premissa, esta pesquisa visa identificar os animais silvestres capturados, suas formas de uso e técnicas de caça em dois mun

8. 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

9. Influence of Helicobacter pylori culture supernatant on the ecological balance of a dual-species oral biofilm
Abstract Dental caries is a chronic progressive disease occurring in the tooth hard tissue due to multiple factors, in which bacteria are the initial cause. Both Streptococcus mutans and Streptococcus sanguinis are main members of oral biofilm. Helicobacter pylori may also be detected in dental plaque, playing an important role in the development of dental c

10. INTEGRATED ENVIRONMENTAL FOOTPRINT INDEX (IEFI): MODEL DEVELOPMENT AND VALIDATION
ABSTRACT: Freshwater is a valuable resource worldwide given the growing demand of the global population. This study aimed to develop and validate an integrated assessment model by means of environmental footprint indices (water, ecological, and carbon), which measure the environmental sustainability of heterogeneous communities, people, and countries. An env
