Benthic marine algae from Cabo Frio region and surroundings: synthesis of knowledge

ABSTRACT

At the last decades, several studies were done about benthic marine algae from Cabo Frio region (RCF), meanwhile the obtained information is scattered in specific publication, monographs and thesis. In this context, the aim of this work is to revise the literature about marine algae from RCF, providing a detailed list of taxa, and analyzing the floristic composition and geographical distribution of benthic marine algae of this importance region from the Brazilian coast. It was found 339 infrageneric taxa, distributed in 76 Chlorophyta, 60 Ochrophyta and 203 Rhodophyta. The municipalities with higher number of taxa were Armação dos Búzios (212) and Arraial do Cabo (207). It was found that 20 of the 339 taxa listed presented distribution restricted to RCF when comparing with the taxa registered to the Brazilian coast and that 8 taxa presented affinities with temperate waters. The species Pseudolithoderma moreirae Yoneshigue & Boudouresque and Gracilaria yoneshigueana Gurgel, Fredericq & J. Norris are endemic to RCF. From the obtained data that indicates an elevate species richness and the presence of number species with restricted and discontinued distribution we can affirm that RCF is one of the most important diversity center of marine algae in Brazil.
