In this project we propose the screening of the red macroalgae (Rhodophyta) biodiversity for the State of São Paulo (Brazil), which includes more than 50% of the diversity known for this group in the country. For that, the barcoding technique will be used, supplemented with morphological and geographic distribution. These data will be integrated to the data from BIOTA (1998/04955-3), to generate data, sample and DNA banks. Studies on the biodiversity of marine algae of São Paulo have been carried out since 1950; however, this knowledge is based only on morphological data and only sporadically supplemented with molecular data. The taxonomic identification of red algae is notoriously difficult due to: a relatively simple morphology and anatomy, which are convergent in many species; phenotypic plasticity; and complex life-cycles with heteromorphic stages. The comparisons of DNA sequences have been fundamental for biodiversity studies and for the inference of the relationships among the different groups of organisms. Molecular markers that allow the identification of species have been denominated "barcoding" The barcoding technique generates a great amount of data in relatively short time. These data, organized and available in databanks, can be used for many different types of research, including biodiversity screenings, conservation and the detection of cryptic and exotic species; development of DNA probes for various applications, taxonomy and phylogenetic studies, ecophysiology, forensics, etc. This project is pioneer in the country for algae, and might be used as a model for other similar projects in the country.
