Photosynthates released by benthic primary producers (BPP), such as reef algae and scleractinian corals, fuel the dissolved organic carbon (DOC) production on tropical coral reefs. DOC concentrations near BPP have repeatedly been observed to be elevated compared to those in the surrounding water column. As the DOC release of BPP increases with increasing light availability, elevated DOC concent...
Two new species of the genus Rissoella Gray, 1847 are described from Venezuela, one from the National Park Morrocoy, Rissoella morrocoyensissp. n. and the other from the Wildlife Refuge Isla de Aves, Rissoella venezolanicolasp. n.Rissoella morrocoyensissp. n. has a deep umbilicus (partly closed), preumbilical cord, black head, hypobranchial gland marked by a pale yellow boomerang-shaped ribbon ...
Abstiact: When offered single species of seaweeds in excess amounts, the sea urchin Arbuciapunctulata (Lamarck) Philippi consumed significantly more Gracilana folijr,a (Forsskal) Borgrsen and Codium z3thmocladium Vickers than Sargassum filipendula C. Agardh, Padina vickersiae Hoyt, or Dictyota dichotomu (Hudson) Lamouroux. When all five species were offered to urchins simultaneously, patterns o...
Background: This study was done to determine the effect of root extract of Acalypha indica Linn (akar kucing) in protecting neuron viability of the rat hippocampus on tissue culture in hypoxic condition. Methods: This is an experimental study of in vitro primary cell culture of hippocampus of Sprague Dowley adult rat. The cultures were group into control (C) and exposure to root extract of Acal...
Marine brown alga Dictyota dichotoma (Dictyotaceae) collected from the Karachi coast of the Arabian Sea has yielded three new C-16 oxidized seco-dolastanes (diterpenoids) named dichotenol-A, B and C. Their structures have been characterized with the aid of 2D-NMR spectroscopic techniques.
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 ...
BACKGROUND Tamarindus indica L is one of the indigenous fruit tree species that traditionally contributes to food security and ecosystem stability in sub-Saharan Africa. We hypothesized that the indigenous people of Eastern Uganda have used T. indica for generations and developed practices that promote its conservation and therefore we expected that they possess an elaborate indigenous knowledg...
