13. Papel de sinais cromáticos na identificação de parceiros sexuais em sagüi comum (callithrix jacchus)
The literature concerning color vision shows a trichromatic advantage in detecting ripe fruits and young leaves, but there are contradictory results. There is also the suggestion of this type of vision being adapted to perceive socio-sexual signals. Indeed, Old World primates utilize the skin color of conspecifics as a factor of attraction. But in New World

14. Determinação do perfil de compostos voláteis e avaliação do sabor e aroma de bebidas produzidas a partir da erva-mate (Ilex paraguariensis)
Volatile compounds from green and roasted yerba mate were analyzed by gas chromatography/mass spectrometry and the flavor profile from yerba mate beverages was determined by descriptive quantitative analyses. The main compounds tentatively identified in green mate were linalool, alpha-terpineol and trans-linalool oxide and in roasted mate were (E,Z)-2,4-hept

15. In vitro antioxidant activity of extracts of green and roasted mate (Ilex paraguariensis) and green tea (Camellia sinensis) / Avaliação da atividade antioxidante in vitro de extratos de erva-mate (llex paraguariensis) verde e tostada e chá verde (Camellia sinensis)
Objetivo. Diversos produtos de origem vegetal vêm sendo estudados por serem fontes de antioxidantes, podendo ser uma alternativa aos antioxidantes sintéticos. Este trabalho avaliou a atividade antioxidante in vitro de extratos de erva-mate (Ilex paraguariensis) verde e tostada e de chá verde (Camellia sinensis). Métodos. Extratos aquosos, etanólicos e e

16. Rapid evolution of sex-related genes in Chlamydomonas
Biological speciation ultimately results in prezygotic isolation—the inability of incipient species to mate with one another–but little is understood about the selection pressures and genetic changes that generate this outcome. The genus Chlamydomonas comprises numerous species of unicellular green algae, including numerous geographic isolates of the spe

17. Yeast Chromatin Assembly Complex 1 Protein Excludes Nonacetylatable Forms of Histone H4 from Chromatin and the Nucleus
In yeast, the establishment and maintenance of a transcriptionally silent chromatin state are dependent upon the acetylation state of the N terminus of histone proteins. Histone H4 proteins that contain mutations in N-terminal lysines disrupt heterochromatin and result in yeast that cannot mate. Introduction of a wild-type copy of histone H4 restores mating,
