Quiénes Somos

Las líneas de investigación se centran en la Interacción Organismo – Medio ambiente; Efecto toxinas dinoflagelados sobre fisiología moluscos, y Respuestas funcionales de los organismos marinos frente a variables ambientales.

Se estudia el grado de plasticidad fisiológica de los organismos frente a fluctuaciones naturales y/o alteraciones antropogénicas del medio ambiente. Se incluyen mediciones de procesos fisiológicos relacionados con la adquisición (filtración, ingestión, absorción) y utilización (respiración, excreción) de energía por parte de los organismos, tanto bajo condiciones ambientales como bajo condiciones controladas de laboratorio. Esta información permite integraciones fisiológicas, tales como el potencial de crecimiento (scope for growth), eficiencia de crecimiento neto (K2) y relación Oxígeno/Nitrógeno (O/N) en invertebrados marinos, índices que permiten evaluar la adecuación biológica de los organismos en determinadas etapas de su ciclo de vida.
