1. Reproductive phenology of aquatic macrophytes in the Cerrado-Pantanal ecotone
ABSTRACT Studies of plant phenology have been performed predominantly with terrestrial species and rarely so with aquatic communities. Such plants are fundamental for the aquatic ecosystems, representing a valuable source of resources when they are scarce in terrestrial environments for the fauna. Studies of phenology help to understand the reproduction rhyt

2. Ideal harvesting point of ‘Limeira-IAC382’ trifoliate orange fruits for seed extraction
Resumo O trifoliata é um dos porta-enxertos de maior uso no mundo, principalmente por proporcionar produção de frutos de excelente qualidade. Dentre os fatores que determinam a qualidade fisiológica das sementes está a colheita de frutos na época correta. Objetivou-se com este trabalho monitorar alterações físico-químicas em frutos de trifoliata L

3. Phytodesalination of a moderately saline soil combined with two inorganic amendments
ABSTRACT The shortage of water and the increasing salinity are the main limiting environmental factors that directly affect the establishment and the development of crops. In this research, phytodesalination capacity of Sesuvium verrucosum was evaluated alone and in combination with agricultural gypsum (CaSO4·2H2O) and Polisul-C, in order to remedy a modera

4. Relationship of Neotropical otter vestiges with environmental and anthropogenic factors
RESUMO A lontra neotropical, Lontra longicaudis é um mustelídeo semiaquático que usa seu habitat de diferentes formas. Para entender a influência relativa de fatores antrópicos e ambientais sobre a distribuição de lontras neotropicais, nós conduzimos monitoramentos sistemáticos de vestígios de lontras na região do médio Rio Guamá, Pará, Amazôn

5. Challenges to improve the biopharmaceutical properties of poorly water-soluble drugs and the application of the solid dispersion technology
ABSTRACT The oral solid dosage forms are extremely relevant to drug therapy and responsible for much of the pharmaceutical industry turnover worldwide. However, the development of medicines in solid form involves significant challenges, including obtaining formulations with appropriate bioavailability for low aqueous solubility drugs (classes II and IV of th

6. Does the landscape surrounding streams affect the occurrence of freshwater crabs? A case study of the genus Aegla (Crustacea: Decapoda: Anomura) in subtropical basins
ABSTRACT Changes in the landscape where watersheds are located may affect the stream biota in different ways. In order to explore this idea, we collected freshwater crabs of the genus Aegla Leach, 1820 in subtropical region of southern Brazil. We also measured a number of landscape features and physico-chemical variables in the collection streams and surroun

7. The contribution of environmental factors to fish assemblages in the Río Acahuapa, a small drainage in Central America
ABSTRACT The ichthyofauna of the Río Acahuapa was analyzed sampling 17 sites that included the basin main channel and its tributaries. Fish were collected using dip-nets, seine-nets and electrofishing. Fish standard length and species abundance were recorded. Species origin and salinity tolerance criteria were used to classify fish species. Water physicoche

8. PROPIEDADES FISICOQUÍMICAS DE MIELES MONOFLORALES DE ENCENILLO DE LA ZONA ALTOANDINA EN BOYACÁ, COLOMBIA
Honey is the natural product with sweetening properties more widely known, is produced by bees from the nectar of flowers and secretions from the plants. Its physicochemical properties depend on the season of harvest, environmental factors prevailing in the harvest period and the biogeographic zones. The aim of this work was focused in honeys produced by Wei

9. Physicochemical and sensory characteristics of pan bread samples available in the Brazilian market
Pan bread samples available in the Brazilian market were evaluated for their physicochemical and sensory characteristics. Twelve pan breads, seven white and five whole grain breads, were evaluated. Moisture, water activity (Aw), firmness, and color (L*, a*, b*) of the crumb were evaluated on the first, fourth, seventh, and tenth days after purchasing the bre

10. Effects of open drainage ditch design on bacterial and fungal communities of cold waterlogged paddy soils
A field experiment established in 1980 was conducted to evaluate the effects of open drainage ditch applied for water removal on bacterial and fungal communities of cold waterlogged paddy soils in 2011. In this experiment, traditional plate counting and temperature gradient gel electrophoresis were employed to characterize the abundance and diversity of soil

11. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct

12. Obtenção e caracterização do extrato seco Padronizado de Vernonanthura ferruginea (LESS.) H. Rob., Asteraceae (Assa-Peixe) / Obtaining and chacterization of santadardized dry extract of Vernonanthura ferruginea (LESS.) H. Rob., Asteraceae
Vernonanthura ferruginea (Less.) H. Rob. (Asteraceae), a typical plant of the Brazilian savannah, popularly known as assa-peixe, presented analgesic, antiedematogenic, antioxidant and antiulcer activities in scientific studies. But in literature there are no works related to the production of dried extracts of this plant species. In this work, standardized s
