Nine currently accepted species of the genus Sargassum (Phaeophyceae) have been recorded from the Mediterranean Sea: S. acinarium, S. desfontainesii, S. flavifolium, S. furcatum, S. hornschuchii, S. muticum, S. ramentaceum, S. trichocarpum and S. vulgare. Two of them, S. desfontainesii and S. furcatum, are Atlantic species, the Mediterranean range of which is restricted to the Alboran Sea, close to the Strait of Gibraltar. Three species, S. hornschuchii, S. ramentaceum and S. trichocarpum are endemic to the Mediterranean. The presence of S. flavifolium in the Mediterranean, a north-eastern Atlantic species, is at least in part based upon a misidentification and therefore requires confirmation. A taxon collected near Algiers and Annaba (Algeria), here referred to as ‘Sargassum sp. from Algeria’, although sharing most characters with S. flavifolium, also presents some distinctive characters. In the absence of genetic data, confirming or not its taxonomic value, and in the lack of studies on the herbaria containing the types of many species currently considered as synonyms of S. flavifolium, but which are possible candidates for accommodating the Algerian specimens, the authors prefer a conservative approach. They do not describe a new species, which would be premature, but draw attention to a taxon which may be more widely distributed in the Mediterranean rather than solely along the Algerian coasts.

This work presents the elemental, polysaccharide, and fatty acid compositions of benthic aggregates formed by the filamentous brown alga Acinetospora crinita, which are widely spread on the rocky bottoms of the Mediterranean Sea. The aggregates can be characterized as mineralized centers in which regeneration of nutrients and recycling of dissolved organic matter actively occur and favor the development of an abundant phytoplankton community. Analyses of the stable isotopes of C and N display their marine origin and could provide evidence of the processes that occur inside/outside of the aggregates. The monosaccharide compositions of Adriatic and Tyrrhenian mucilages produced by brown alga A. crinita were quite similar. In particular, the Adriatic sample compositions resembled the average composition of the Tyrrhenian high molecular weight exopolymers, and the observed differences could be ascribed to different degradation stages.The fatty acid patterns found for the aggregates were similar to those observed in the isolated A. crinita algae with variable contributions from embedded diatom species. The bacterial contribution to the fatty acid pool was quite low, most likely due to the known poor conditions for their heterotrophic growth.

“…Cauloids bear smooth ovoid tophules (Cormaci et al, 2012;Rodríguez-Prieto et al, 2013;Sauvageau, 1912;Serio, 1995b). Both taxa are endemic to the Mediterranean and are present all across the Mediterranean, including the Adriatic, Aegean and Levantine Seas (Ercegovic, 1980;Giaccone, 1978;Hereu et al, 2008;Ribera et al, 1992;Taskin et al, 2012;Tsiamis et al, 2013Tsiamis et al, , 2014. They are long-lived and display low growth rates and slow population dynamics (Ballesteros et al, 2009;Capdevila et al, 2015Capdevila et al, , 2016.…”

Photosynthetic performances of two deep‐water canopy‐forming fucoid algae across a depth gradient: Interspecific variability and short‐term adaptation to the light environment

Deep‐water canopy‐forming algae Gongolaria montagnei var. compressa and Ericaria zosteroides (Fucales: Ochrophyta) co‐exist in mixed populations, the first taxa dominating at the upper limit of distribution (20 m) and the second at the lower limit (40 m). This depth distribution pattern is consistent with the photosynthetic performances of both taxa, with E. zosteroides showing higher photosynthetic efficiency (α) and lower light at saturation (Ik) and compensation (Ic) than G. montagnei var. compressa. Neither photosynthesis at saturation (Pmax) nor dark respiration showed any significant change at the species level. G. montagnei v. compressa showed higher Pmax and α at 20 and 40 m, but E. zosteroides did not follow the same trend, although both Ik and Ic decreased with depth in this species, pointing to an increased capacity of E. zosteroides to show photo‐adaptation. Each species maintained its Psat values when transplanted from the depth where it was dominant to the depth where it was secondary, but in the case of G. montagnei var. compressa it decreased its Psat when transplanted from 40 to 20 m and in the case of E. zosteroides it increased its Psat when transplanted from 20 to 40 m. These results point to a better photosynthetic performance of E. zosteroides than G. montagnei var. compressa at low‐light conditions, information that can be used to improve success in restoration action plans.
