Chemotaxonomic study of the diterpenes from the brown alga Dictyota menstrualis Valéria Laneuville Teixeira*, Diana Negrão Cavalcanti, Renato Crespo Pereira Departamento de Biologia Marinha, Universidade Federal Fluminense, C.P. 100.644, 24001-970, Niterói, RJ, Brazil b Programa de Pós-Graduação em Quı́mica Orgânica, Instituto de Quı́mica, Universidade Federal Fluminense, 24020-150, Niterói, RJ, ...
Bioassay-guided fractionation of an ethanol extract of the brown alga, Dictyota dichotoma, led to the isolation of a novel chlorine-containing perhydroazulene diterpene together with two known diterpenes, dictyolactone and sanadaol. The structure of the novel compound, named dictyol J, was elucidated on the basis of spectroscopic information. Dictyolactone showed the highest algicidal activity ...
Live scleractinian corals are a prime microhabitat for many recruiting coral reef fishes, yet live coral cover has exhibited widespread declines, and the impact of this loss on recruiting fishes is not well understood. Although reduced recruitment rates of parrotfishes (Scaridae) have been observed after loss of coral cover, increased juvenile parrotfish abundance observed in connection with in...
