Resumen

La eutrofización marina, originada por un excesivo aporte de nutrientes, está considerada actualmente como un grave problema en numerosas áreas costeras de todo el mundo. En este estudio empleamos la capacidad de las macroalgas (Ulva y Enteromorpha) de integrar el régimen nutritivo de un cuerpo de agua para realizar una sectorización trófica de las bahías estudiadas. Los resultados de la sectorización trófica en función de las macroalgas fueron diferentes a la establecida en función de las concentraciones de nutrientes en agua. Las zonas más internas de las rías fueron las más enriquecidas en cuanto a nutrientes en agua, pareciendo estar las algas más afectadas por condiciones locales específicas, éstas no siguen el gradiente de concentración del interior al exterior que se observaba en el agua. La falta de correspondencia entre los nutrientes en agua y algas en este estudio puede ser debido a la gran heterogeneidad en las condiciones nutritivas que encontramos en áreas costeras, de forma que las muestras de algas intermareales no hayan reflejado adecuadamente los niveles de nutrientes del interior de las masas de agua estudiadas.
