The use of digital photography for the definition of coastal biotopes in Azores.
Álvaro, Nuno V.; Wallenstein, Francisco; Neto, Ana I.; Ferreira, João G.; Nogueira, Eunice M.; Santos, Catarina I.; Amaral, A. F.Copyright © Springer Science+Business Media B.V. 2007. ; Sampling benthic communities usually requires intensive field and lab work which is generally performed by skilled staff. In algal dominated communities, like those on the shores of the Azores, biotope characterization studies focused on the more conspicuous algae categories, thus reducing the skills required for species identification. The present study...
Algae-based biotopes of the Azores (Portugal): spatial and seasonal variation.
Wallenstein, Francisco; Neto, Ana I.; Álvaro, Nuno V.; Santos, Catarina I.Copyright © Springer Science+Business Media B.V. 2007. ; The increasing importance of coastal management created the need for a systematic classification and characterization of marine communities. Accurate quantitative methodologies for rocky shore algae-based biotope definition, were developed and tested on the Islands of São Miguel and Santa Maria (Azores). Shores of both islands were surveyed, covering all...

Synthesis of tricyclic isoindoles and thiazolo[3,2-c][1,3]benzoxazines
Pinho e Melo, Teresa M. V. D.; Santos, Catarina I. A.; Rocha Gonsalves, António M. dA.; Paixão, José A.; Beja, Ana M.The thermolysis of (3R,9bS)-5-oxo-2,3,5,9b-tetrahydrothiazolo[2,3-a]isoindole-3-carboxylic acids in Ac2O led to novel 3-methylene-2,5-dioxo-3H,9bH-oxazolo[2,3-a]isoindoles and chiral (9bS)-5-oxo-2,3,5,9b-tetrahydrothiazolo[2,3-a]isoindoles were obtained on FVP. Starting from -cysteine methyl ester (3R,10bR)-5-oxo-2,3-dihydro-10bH-[1.3]thiazolo[3,2-c][1,3]benzoxazines were obtained as single stereoisomers. The t...
Synthesis of novel tricyclic isoindole derivatives
Melo, Teresa M. V. D. Pinho e; Santos, Catarina I. A.; Gonsalves, António M. d'A. Rocha; Paixão, José A.; Beja, Ana M.; Silva, Manuela RamosNovel 3-methylene-2,5-dioxo-3H,9bH-oxazolo[2,3-a]isoindoles were prepared from the thermolysis of (3R,9bS)-5-oxo-2,3,5,9b-tetrahydrothiazolo[2,3-a]isoindole-3-carboxylic acids in acetic anhydride. The structure of 3-methylene-2,5-dioxo-3H,9bH-oxazolo[2,3-a]isoindole 6a was determined by X-ray crystallography. ; http://www.sciencedirect.com/science/article/B6THS-49PXCD9-X/1/45bd0f04f44115a1e7b644d727569da1
