Marine macrophytes: diversity and applications

Abstract

The research activity deals with several aspects of biology, systematics and ecology of marine macrophytes, with a special focus on macrophytes inhabiting the Mediterranean Sea. In particular, the research focuses on: 1) Marine alien macrophytes (e.g. Caulerpa, Asparagopsis, Halophila) and their interactions with autochthonous macrophytes, with particular attention to Marine Protected Areas. 2) Coralline red algae (Rhodoliths, Lithophyllum byssoides), characterized by a carbonate thallus, which form complex structures that increase the habitat biodiversity and are a key component in the cycle of carbonate budget. Thus, they are of high interest for conservation. 3) Brown algae belonging to the genus Cystoseira sensu lato, considered important habitat formers in the Mediterranean Sea, form communities of great ecological value but at the same time highly threatened. 4) Inter and intraspecific variations of secondary metabolites produced by brown algae as chemical defences, and their biologiccal applications. 5) Citizen science activities on the monitoring of marine alien macrophytes.
