14. Report on the Malungo expedition to the Erepecuru river, Oriximiná, Brazil. Part I: is there a difference between black and white breu?
ABSTRACT Species belonging to Burseraceae produce an oleoresin known in the north of Brazil as breu. They comprise an essential oil with a complex composition, and are used in Amazonia for smoking the environment, to caulk boats and for medicinal purposes. Depending on its organoleptic characteristics and on the breu-producing species, they are called white

15. Xaraés palisadegrass remains productive after the disappearance of stylo in tropical legume-grass pasture
Gradual reduction of legumes in mixed tropical pastures requires periodic oversowing. Exploiting the carrying capacity of grass for an extra year after the disappearance of legumes can be economically advantageous to the farmer. This study aimed to evaluate the productivity of Xaraés palisadegrass (Brachiaria brizantha) pastures in response to its historica

16. Characterization saprobic fungi on leaf litter of two species of trees in the Atlantic Forest, Brazil
Abstract We investigated the composition and structure of fungal communities associated with leaf litter generated by Clusia nemorosa and Vismia guianensis that belong to phylogenetically-related botanical families and exist together in a remnant of the Atlantic Forest in Bahia, Brazil. Samplings were conducted during wet (June 2011) and dry (January 2013) s

17. Simaroubaceae family: botany, chemical composition and biological activities
The Simaroubaceae family includes 32 genera and more than 170 species of trees and brushes of pantropical distribution. The main distribution hot spots are located at tropical areas of America, extending to Africa, Madagascar and regions of Australia bathed by the Pacific. This family is characterized by the presence of quassinoids, secondary metabolites res

18. In situ rumen degradation kinetics as affected by type of pasture and date of harvest
Botanical composition affects the nutritive value and nutrient degradation kinetics of pastures. However, there is little information about pastures composed of various species. The present study was conducted to evaluate in situ degradation kinetics of dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) of a naturalized non fertilized past

20. Chemical and botanical characterization of Chilean propolis and biological activity on cariogenic bacteria Streptococcus mutans and Streptococcus sobrinus
Propolis is a non-toxic natural substance with multiple pharmacological properties including anticancer, antioxidant, fungicidal, antibacterial, antiviral, and anti-inflammatory among others. The aim of this study was to determine the chemical and botanical characterization of Chilean propolis samples and to evaluate their biological activity against the car

21. Caracterização da vegetação, desempenho e seletividade de ovinos em caatinga raleada sob lotação contínua, Serra Talhada-PE.
A vegetação da Caatinga é um importante recurso forrageiro para o rebanho da região semiárida brasileira. Objetivou-se caracterizar a vegetação e o desempenho animal, bem como a seletividade de ovinos, ao longo do ano, em Caatinga raleada, no município de Serra Talhada-PE. Para tal, a pesquisa consistiu em levantamento de dados da vegetação e dos o

23. Dynamics of sward condition and botanical composition in mixed pastures of marandugrass, forage peanut and tropical kudzu
This study was carried out to evaluate the dynamics of sward condition and botanical composition of a mixed pasture of marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides), rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight).

24. Avaliação dos impactos na vegetação após a exploração madeireira em floresta ombrófila densa de terra firme no Município de Caracaraí - RR
Changes on floristic composition and phytosociological and damage we evaluated in forest subjected to reduced-impact logging (RIL) in the municipality of Caracaraí in the state of Roraima. The experiment consisted in the installation of nine permanent plots (1 ha each), under the completely randomized design with three replications and three treatments (T1
