Última Do population and community metrics tell the same story about recent changes in Northern Mediterranean fish communities? ArchiMer Rochet, Marie-joelle; Trenkel, Verena; Gil De Sola, Luis; Politou, Chrissi-yianna; Tserpes, George; Bertrand, Jacques. This document presents a comparative study of human impacts on the length-structure of fish communities across North-Mediterranean ecosystems. We use survey data to examine trends in length-based metrics and their consistency within and among the two levels of organisation populations and communities, and to suggest interpretations of observed trend combinations. We start from a set of population processes potentially affected by human pressures: fishing will induce mortality especially in target species, whereas the hydrological environment and eutrophication potentially affect recruitment and individual growth. How population changes will be reflected at the community level is expected to depend on community evenness. Based on this expectation, a...
