Brown algae from genus Cystoseira s.l. form dense underwater forests that represent the most productive areas in Mediterranean Sea. Due to combined effects of global and local stressors such as climate change, urbanization, herbivore outbreaks, there has been a severe decline brown algal Natural recovery depleted sites is unlikely due low dispersal capacity these species, efficient techniques r...

Canopy-forming brown algae support highly productive ecosystems whose decline has been attributed to the interplay of several anthropogenic disturbances. Climate change could have disruptive effects on biology these species, but role temperature in development early life stages is poorly understood. The aim this study was assess response Ericaria giacconei , a winter-reproducing Southern–Medite...

The ability of Cystoseira baccata algal biomass to remove Hg(II) from aqueous solutions is investigated. The mercury biosorption process is studied through batch experiments at 25 degrees C with regard to the influence of contact time, initial mercury concentration, solution pH, salinity and presence of several divalent cations. The acid-base properties of the alga are also studied, since they ...

Sodium alginates were extracted from brown seaweeds (Cystoseira schiffneri) collected a Tunisian island (Kerkennah, Sfax) in different seasons (December, April, July and September). The structural features antioxidant properties of C. schiffneri sodium (CSSA) characterized. Micro-elementary analysis showed the absence nitrogen sulfur alginate fractions. All isolates high uronic acids (47.4–66.4...

Cystoseira sensu lato marine forests, which are among the most productive and diverse systems in rocky intertidal subtidal habitats of Mediterranean Sea, experiencing a widespread decline throughout basin due to increasing human pressures. Yet it is still unclear whether Marine Protected Areas (MPAs) may represent effective tools for conservation these important habitat formers their associated...
