| dc.description.abstract | The benthic algal communities of two subtidal sites, located on opposite coasts of São Miguel island (São Roque in the south and São Vicente on the north coast), were studied over a 2 year period (September 1993-September 1995). At both sites the sublittoral region was surveyed from low-tide level down to a depth of 15 m. Qualitative and quantitative changes are described. A depth-related gradient in species diversity and biomass was found at both localities. In general, red algae such as corallines and Pterocladiella capillacea predominated in the shalow sublittoral (5 m) while brown algae such as Zonaria and Stypocaulon were more abundant at 15 m. Multivariate analyses emphasized the existence at each study site of two communities (5 and 15 m depth), separated by a large transition zone. The 15 m community on the south coast site showed the largest number of species (52), whereas the lowest diversity (30 species) also occured at this site in the 5 m community. A clear seasonal pattern of biomass change could be discerned only at São Vicente wherethe highest biomass was recorded in spring-summer. Nomajor inter-annual variations could be detected, indicaring relatively stable communities at least on a short-term basis. | en |
