Ulva lacinulata constitutes a critical yet often overlooked component of Mediterranean eutrophicated coasts. Investigating its physiological responses to weather events may enable environmental management and aquaculture applications. Field sampled U. lacinulata , a subtropical to water-temperate species, from the eutrophic Thessaloniki Bay, Greece, and studied it under laboratory conditions. Field seawater variables were corr...

Coastal protection from erosion is an important ecosystem service provided by marine vegetation. Seaweeds and seagrasses can attenuate wave action in coastal areas and increase sediment retention. Here we investigated for the first time the effects of erect Cystoseira sensu lato forests in attenuating the wave energy in two Mediterranean shallow areas (Greece and Tunisia). The hydrodynamic effects were measured using the disso...

Algal habitat-forming forests composed of fucalean brown seaweeds ( Cystoseira , Ericaria , and Gongolaria ) have severely declined along the Mediterranean coasts, endangering the maintenance of essential ecosystem services. Numerous factors determine the loss of these assemblages and operate at different spatial scales, which must be identified to plan conservation and restoration actions. To explore the critical stressors (n...
