Checklist of Cyanobacteria from São Paulo State, Brazil

Abstract

Based on the literature about the cyanobacteria from Brazil and particularly from São Paulo State, the list of Brazilian flora and the data bank of herbaria collections, a total of 460 species were referred to Brazil and 378 to São Paulo State. Taking into account that the group of cyanobacteria presents around 2800 species, these numbers represent much less than 20% of the known species. Considering the diversity of environments and habitats in the tropical/subtropical biomes compared to the reduced number of known species, this biodiversity is certainly underestimated and should be much larger.
