“…Moreover, they are under surveillance by the IUCN (International Union for Conservation of Nature), the Berne Convention (Council of Europe, 1979) [53] and the Barcelona Convention (UNEP/MAP, 2009) [54]. Since these algae are particularly sensitive to variations of environmental factors [24,55,56], the Water Framework Directive (WFD, 2000/60/EC) [57] and the Marine Strategy Framework Directive (MSFD, 2008/ 56/EC) [58] considered them as reliable indicators of environmental quality in Mediterranean coastal waters [59,60]. Human pressures are increasingly limiting their distribution, and most of these algae are currently experiencing a severe decline in many Mediterranean regions [26,55,[61][62][63].…”

Biodiversity is undergoing rapid and worrying changes, partially driven by anthropogenic activities. Human impacts and climate change (e.g., increasing temperature and ocean acidification), which act at different spatial scales, represent the most serious threats to biodiversity and ecosystem structure and function. In the Mediterranean Sea, complex systems such as fucoid algae and seagrasses, characterized by a high associated biodiversity, are regularly exposed to natural and anthropogenic pressures. These systems, particularly sensitive to a variety of stressors, evolved several physiological and biochemical traits as a response to the different pressures which they are subjected to. For instance, they produce a huge quantity of secondary metabolites such as phenolic compounds, to adapt to different environmental stressors and to defend themselves from biological pressures. These natural products are receiving increasing attention due to their possible applications in a wide range of industrial sectors. In this paper we provide an overview on the ecological role of phenolic compounds from the genus Cystoseira sensu lato and Posidonia oceanica (L.) Delile, also highlighting their potential use as ecological biomarkers.

“…The highest level of macroalgal complexity in the NW Mediterranean Sea is represented by canopy‐forming Cystoseira sensu lato species (Fucales). These iconic Mediterranean Cystoseira forests are currently facing a decline, with important losses of the three‐dimensional habitat for local species, and important consequences for biodiversity and ecosystem functioning (Bulleri et al ; Thibaut et al ; Mangialajo et al ; Mineur et al ; Thibaut et al ; Blanfuné et al ; Gianni et al ).…”

Canopy-forming algae play a key role in temperate coastal ecosystems sustaining complex habitats that provide food and refuge for rich associated biotic communities. These macroalgae are in decline in many coastal areas, where overgrazing by herbivores can lead to the loss of these highly structured and diverse habitats toward less complex sea urchin barren grounds. Once established, low productive barren grounds are considered stable states maintained by several positive feedback mechanisms that prevent the recovery of marine forests. To revert this global decline, restoration efforts and measures are being encouraged by EU regulations and local actions. Here, we tested the success of active revegetation techniques as a tool to promote functional and productive Treptacantha elegans forests in sea urchin barren grounds under different restoration strategies (active, and combined active with passive strategies). Active revegetation was performed in 6 barren grounds, 3 located inside a Mediterranean No-Take marine reserve (active and passive strategy) and 3 outside (active strategy alone), following a three-step protocol: (1) sea urchin population eradication, (2) seeding with Treptacantha elegans, and (3) enhancement of T. elegans recruitment. Revegetation success was assessed 1 year later in the six barren grounds, but was only achieved after combining active with passive restoration strategies. Our results encourage revegetation of barren grounds to shift from less productive habitats to complex T. elegans forests, highlight the potential of the combined passive and active restoration strategies, as well as the important role of marine reserves not only in conservation but also in ecological restoration.
