Floristic study on benthic marine algae of Bahia Concepcion, B.C.S., Mexico

Abstract

Results are presented of a study on the algae from the waters of Bahía Concepción, B.C.S., in the Gulf of California. The floristic list includes data on the species found, the state of reproduction, tidal levels, type of coast, substrate and epiphytism. Sixty-three species of Rhodophyta, 22 species of Phaeophyta and 18 species of Chlorophyta were identified. The presence of various species in relation to light, temperature and substrate is discussed. The Rhodophyta dominated in terms of species diversity. The algal flora of Bahía Concepción is tropical and its greatest species diversity is found in spring.
