Observations on Enhancement & Inhibition by Light of Triphosphopyridine Nucleotide Photoreduction in Preparations of Laurencia obtusa (Hudson) Lam.
The alga, Laturencia obtutsa (Hudson) Lam., was collected between 7 and 8 AM from an off-shore reef (Cayo Enrique) at La Parguera, Puerto Rico. All plants came from one location on the reef at ca. one foot depth. They were stored in open-sea water under daylight, and used within 6 hours of harvest. Terminal fronds of similar coloration from the same clump w-ere taken for each experiment. Severa...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Chemical Composition of Laurencia obtusa Extract and Isolation of a New C15-Acetogenin.
A new C15-acetogenin, sagonenyne (20), exhibiting an unusual single tetrahydropyran ring was isolated from an ethyl acetate extract of Laurencia obtusa collected on the Corsican coastline. Its structure was established by detailed NMR spectroscopic analysis, mass spectrometry, and comparison with literature data. Twenty-three known compounds were identified in the same extract by means of colum...

15 صفحه اولEcological roles of natural products of the Brazilian red seaweed Laurencia obtusa.
Laboratory and field experiments were performed to assess the ecological roles of natural products produced by the Brazilian red seaweed Laurencia obtusa. Laboratory assays revealed that the natural concentration of the crude organic extract of L. obtusa significantly inhibited feeding by two herbivores: the crab Pachygrapsus transversus and the sea urchin Lytechinus variegatus. It was verified...
