| Abstract | Nowadays, many anthropogenic perturbations threaten the Mediterranean Sea. Posidonia oceanica , its endemic phanerogam, is often used as a pollution descriptor but does not react very fast because of its low turnover rate. This research project proposes to use the microbenthic loop (bacteria, organic matter, meiofauna and microphytobenthos) present in this ecosystem to detect perturbations earlier and enter those results in the calculation of the exergy index (Fig.1). This index expresses the distance of an ecosystem, at a given state, from its equilibrium. The higher it is, the closer from its optimum state (climax) the ecosystem is.
