Relació entre la distribució de nutrients i oxigen dissolt i la composició elemental del fitoplàncton a la Mar Catalana (N - O Mar Mediterrània)

Abstract

Aquesta tesi ha estat realitzada gràcies al suport dels projectes : • CANYONS (Estudio multidisciplinar de la dinámica de un cañón submarino y su repercusión sobre la ecología del margen continental del Mediterráneo Noroccidental. 1999-2002, CYCIT, MAR99-1060-C03), • HABES (Harmful Algal Bloom Expert System, EU, EVK2-CT-2000-00092), • PUDEM (Morfodinámica de playas urbanizadas: integración de datos experimentales y modelos teóricos. 2003-2006, MEC, REN2003-06637-C02), i • CACO (Estudio del efecto del cambio global en comunidades marinas del Mediterráneo noroccidental, MEC, REN2002-01339/MAR) així com a la concessió d’una beca predoctoral I3P-Generales del CSIC, i una beca predoctoral del CSIC a càrreg del projecte CANESP (Population Dynamics and Toxicity of Harmful Microalgae in Coastal Embayments, MEC / National Research Council Canada, 2004 NRC/4) a Mariona Segura i Noguera. L’estança al Laboratori de Microscopia Electrònica i al Departament de Microbiologia de la Universitat de Bergen ha estat finançada amb una beca del Govern Noruec (Cultural Agreement between Norway and Spain, Norwegian Government Scholarship 2005/2006) concedida a Mariona Segura i Noguera

El present treball es planteja l’estudi de les relacions que s’estableixen entre els elements químics essencials des d’un punt de vista biològic, tant a l’interior de les cèl·lules del fitoplàncton, com a l’exterior, és a dir a la mar. Els elements essencials són el carboni (C), l’hidrogen (H), el nitrogen (N), l’oxigen (O), el fòsfor (P) i el sofre (S) (Reynolds, 1997). L’interès en l’estudi d’aquests elements rau en que permeten moure’ns entre diferents nivells d’organització biològica, mitjançant l’estudi de les relacions entre els elements (estequiometria), i mitjançant l’estima de fluxos i balanços de massa entre i des d’una gran varietat d’entitats biològiques, des d’orgànuls i cèl·lules fins a conques senceres o fins tota la biosfera (Sterner i Elser, 2002).
