Seaweed have gained increased interest due to their promising applications within food, cosmetic and health industries. In addition to macroalgae obtained by harvesting or cultivation, beach-cast macroalgal wracks can be an alternative source of added-value compounds. In several coastal areas, thousands of tons of macroalgae are cast on beaches and shorelines. Although these phenomena play a part in coastal ecology, the occurrence of massive amounts of decaying biomass in these areas conflict with human use.

These massive amounts of biomass are usually removed to dumping grounds or the sea, which is both costly and a waste of a resource so, it would be very interesting if this biomass could be removed, allowing the extraction of added-value compounds. In this context, the European project MacBioBlue is in progress and the results are presented below.

In the present work, extracts from beach-cast macroalgae from Gran Canaria, Spain were prepared and antiaging and anticholinesterasic activities of those extracts were assessed. The extracts were further fractionated and the most active fractions were characterized. Very interesting activities were obtained from the majority of the extracts and fractions prepared, which indicates the anti-aging potential of this natural resource and shows the potential of using beach-cast macroalgal wracks for the isolation of new added-value compounds.

The objective of this course is to introduce participants to the details of communicating science to non-specialized audiences, including, but not exclusive to, public and private stakeholders, students and teachers, and media professionals.

Conversa com Galopim de Carvalho.

The course aims at providing an introduction to stable isotopes ratios as tools to understand global, ecosystem and community level bio/geo cycles; light isotopes: H, N, C, O and S isotopes, geo cycles and ecological significance; sampling and analytical methodologies in stable isotope analysis.

This course aims to evidence the importance of natural history collections for the study of biodiversity, to show new tools and approaches to extract and disseminate biodiversity data from natural history collections and to increase awareness of young researchers for the scientific and cultural value of Natural History Museums.
