Bernat Hereu

Bernat Hereu Fina is the junior coordinator of the group and a lecturer at the University of Barcelona’s Department of Ecology. He began his scientific career with biological monitoring of the Medes Islands Protected Area, which allowed him to develop his thesis on trophic interactions among fish, urchins and algae. Before rejoining the University of Barcelona, he undertook postdoctoral stages at the Université de Nice-Sophia Antipolis (France) and at Moss Landing Marine Laboratories (USA), where he further developed his studies on the ecology of algae communities. His current research focuses on two central issues: the study of the dynamics and functioning of algae communities from a conservationist point of view, and the efficiency of marine reserves for the recovery of fish populations and their exploitation. In this research he uses visual, marking and telemetry techniques.
