La comunidad de "Cystoseira baccata" (Fucales, Ochrophyta) en el noroeste ibérico

Abstract

Summary The biology and phycology biodiversity of the community of Cystoseira baccata in the northwest of the Iberian Peninsula is studied, an exclusive Atlantic species, widely distributed along the coast but little known. Information is provided from 30 locations sampled from March 2015 to July 2018 at a depth interval from the lower intertidal to the subtidal (5 m). We obtain the biometric data of 2264 specimens of C. baccata and the epiphytes of 941 plants have been analyzed. In total, 230 epilithic and epiphytic species have been cataloged. With all the information, the biology and habitat of C. baccata has been characterized, as well as the phycological diversity of the community. The changes produced in the community in different periods, both short and long term, were also analyzed. In addition, the seasonal dynamic of the biological characteristics of C. baccata and its associated flora, both substrate and epiphyte, was studied. This work provides information necessary for the knowledge and management of the community of C. baccata in the Iberian northwest.
