Pigmentos carotenoides del camarón Artemesia longinaris Bate (Crustacea, Decapoda, Penaeidae)
Provedor de dados: 20
Autores: Carreto, J.I.; Carignan, M.O.
Caronetoids from caparace and internal organs of Artemesia longinaris were isolated and identified. The following carotenoid pigments were found in caparace: luteine, tunaxanthin diester, astaxanthin monoester and free astaxanthin. A much greater variety of pigments was isolated from internal organs: Ó- doradexanthin, a fucoxanthin derivate, chlorophylls degradation products and various xanthophylls in trace amounts. These pigments are of dietary origin. In the natural environment, A.longinaris takes preformed astaxanthin from the diet and transfers it to body tissues.

Phytoplankton composition in coastal lagoons of different trophic status in Northern Colombia determined by microscope and HPLC-Pigment analysis
Provedor de dados: 20
Autores: Gocke, K.; Meyerhöfer, M.; Mancera P., J.E.; Vidal, L.A.
The regional differences in the composition of the phytoplankton assemblages in several coastal lagoons of the “Outer Delta of the Río Magdalena” (Caribbean coast of Colombia) were determined using microscopic counting and HPLC-pigment measurements. The study sites can be classified as 1) a group of limnic lagoons with relatively low (5.5-19 µg/l) chlorophyll a (chl a) concentrations and high inorganic suspension loading, 2) a group of brackish lagoons with high (62-90 µg/l) chl a concentrations and high amounts of organic seston, (two further lagoons form a transition between group 1 and 2, and 3) a fully marine Caribbean bay with very low (0.3 µg/l) chl a and seston concentrations. The regional variations in salinity of the lagoons are due to inflow of...

Distribución de clorofila "a" y feopigmentos en el Estrecho Bransfield, Bahía Chile y Paso Drake durante el verano de 1998 (Antártica)
Provedor de dados: 20
Autores: Torres Ch., G.
Se estima la productividad primaria en concentración de clorofila "a" y feopigmentos, como indicativo de la calidad del primer nivel trófico-fitoplancton, registradas en el Estrecho Bransfield, Bahía Chile (Noreste de la Isla Greenwich) y en el Pacífico Drake, durante la VII Expedición Ecuatoriana a la Antártida a bordo del B/I ORION durante el verano austral de 1998. La biomasa fitoplanctónica superficial de clorofila "a" en el Estrecho Bransfield, registró las mayores concentraciones (0.7-08 mg/m3) hacia el noreste del estrecho, y las menores concentraciones de 0.2 mg/m3 se localizaron hacia el centro. A nivel subsuperficial de los 20 m se registraron las más altas concentraciones de toda la columna de agua (0-100 m), con una distribución latitudinal...
