14. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima

15. Micronutrientes e metais pesados tóxicos: do fertilizante ao produto agrícola / Micronutrients and toxic heavy metals: from fertilizer to agricultural product
The presence of toxic heavy metals in fertilizers has been a big concern. It has been indicated as one of the obstacles to sustainable food production. On the other hand, there is a growing demand for better-quality products, with high micronutrient content and low malnutrition factors, such as toxic heavy metals. In Brazil there are scarce number of studies

16. Efeito do extrato bruto e da fração alcaloídica de Erythrina velutina em camundongos submetidos ao labirinto em cruz elevado e ao modelo de esquiva inibitória do tipo descida da plataforma
In the popular therapy Erythrina velutina (EV), plant family Fabaceae, is used as an analgesic, anticonvulsant, anxiolytic or sedative and combating insomnia. Previous studies performed in rodents suggest that extracts of EV have anxiolytic and amnesic effect. In this context, the objective of this study was to investigate the effect of gross extract and alk

17. Frugivory of Ficus (Moraceae) by birds in areas with different levels of forest fragmentation in São Paulo State / Frugivoria de Ficus (Moraceae) por aves em paisagens com diferentes níveis de fragmentação florestal no Estado de São Paulo
Ficus (Moraceae) é o gênero mais importante para animais frugívoros nas florestas tropicais, considerado um recurso-chave durante períodos de escassez de frutos. Esses animais dispersam suas sementes e contribuem para a manutenção das populações de figueiras. A perda de hábitat e a fragmentação da paisagem podem afetar a sobrevivência de populaç

19. Cálcio e boro para soja-perene: características anatômicas e agronômicas e concentração de nutrientes / Calcium and boron for perennial soybean: anatomical and agronomic characteristics and nutrient concentrations
Forage legumes have been mixed with grasses and contributed to improve the sustainability of the soil- plant- animal system. Perennnial soybean (Neonotonia wightii) is one forage legume well adapted to the tropical areas. Calcium and boron have resulted in benefits for plant development, particularly in legume species. This study was set with the objectives

20. Exigências em proteína e energia e valor biológico de alimentos para o dourado Salminus brasiliensis / Protein and energy requirements and biological value of selected feedstuffs for the dourado Salminus brasiliensis
The dourado, Salminus brasiliensis, presents excellent farming characteristics, such as fast growth and excellent flesh quality. However, the lack of the knowledge on the species nutritional requirements and biological value of feedstuffs hamper the formulation of diets for optimized performance and, consequently, the speciesintensive farming. To determine d

24. Interações entre o morcego Sturnira lilium (Chiroptera: Phyllostomidae) e plantas da família Solanaceae / Interactions between the bat Sturnira lilium (Chiroptera: Phyllostomidae) and plants of the family Solanaceae
Bats have a high ecological importance in the Neotropics for they are highly diverse, very abundant and interact with many plant and animal species. Phyllostomid bats of the subfamily Stenodermatinae are specialized frugivores and important seed dispersers, and Sturnira lilium prefers fruits of the Solanaceae, a family of high ecological and economical value
