The Costa Concordia shipwreck permitted to assess how multiple disturbances affected marine biota at different spatial and temporal scales, evaluating the effects of mechanical and physical disturbances on Posidonia oceanica (L.) Delile, an endemic seagrass species of the Mediterranean Sea. To assess the impacts of the shipwreck and its salvaging from 2012 to 2017 at a population and a landscape level, a diversified approach was applied based on the application of a geographical information system coupled with seascape metrics and structural descriptors.

A new high-resolution pollen and NPP (non- pollen palynomorph) analysis has been performed on the sediments of Lake Dojran, a transboundary lake located at the border between Greece and the former Yugoslav Re- public of Macedonia (FYROM). The sequence covers the last 12500 years and provides information on the vegeta- tional dynamics of the Late Glacial and Holocene for the southern Balkans. Robust age model, sedimentological di- atom, and biomarker analyses published previously have been the base for a multi-perspective interpretation of the new palynological data.
