Abstract

This work represents the first methodical phycologycal survey in which was determined the specific composition of the community of macroalgae and their spatial and temporary variation at the Ojo d eLiebre lagoon, B.C.S., during 1995. We identified 73 species: 34 of the Rhodophyta division, 27 of the Chlorophyta and 12 of the Phaeophyta. The localities with hard substrate presented a greater richness of species than characterized by soft substrate, being Isla Brosa the one which presented the greatest number of species (47) and Campo Ejidatario the one that presented the smallest one (24). Of the species, 20 were exclusives of someone locality and generally were present during only someone specific season. Changes inthe richness of species were not so evident between the seasons, where the gratest number of species (52) was found in summer and the fwest in spring (39). About composition of species, sesonl changes were more evident, where each locality presented a precise pattern. The species that were widely distributed in the lgoon and were present throughout the season were: Spyridia filamentosa (Wulfen) HArvey, Hypnea valentiae (Turner) Montagne, Chondria dasyphylla (Woodward) C. Agardh, Dasya baillouviana (Gmelin) Montagne, Polysiphonia pacifica Hollenberg and Ectocarpus commensalis Setchell y Gardner, though each one of them was seasonally different. 43% of the species were of wide distribution, 36% with temperature affinity and 21% with tropical affinity. This indicates that the phycoflora of the lagoon is representative of a temperate-warm transition zone.
