MARBEC MARine Biodiversity, Exploitation and Conservation, est une unité de recherche qui regroupe des personnels de 4 organismes : l’IRD, l’Ifremer, l’UM et le CNRS. Son objectif est l’étude de la biodiversité marine des écosystèmes lagunaires, côtiers et hauturiers à différents niveaux d’intégration, depuis les aspects moléculaires, individuels, populationnels et communautaires, et des usages de cette biodiversité par l’Homme.
