“…The following taxa have been cited in the literature as bloomforming species, some of them as potentially toxic (according to Hallegraeff et al 2003, Fukuyo et al 1990, Odebrecht et al 2002, Moestrup 2004 Although some of them have been recorded for many years, only A. glacialis has been implicated in patch formation on the surf-zone that has caused a negative effect to tourism (M.C. Villac, personal observation) and was possibly associated with a fishkill event in Itanhaém in 1978(Zavala-Camin & Yamanaka 1980. The recent report of C. wailesii, a large size and thus conspicuous diatom, is in conformity with the contention of Fernandes et al (2001) that this is indeed a recently introduced species to the Brazilian coast.…”

Abstract:The objective of this study is to compile the inventory of nearly 100 years of research about the phytoplankton species cited for the coast of the state of São Paulo, Brazil. A state-of-the-art study on the local biodiversity has long been needed to provide a baseline for future comparisons. This type of data is scattered in old scientific journals and in the so-called "grey literature", and are in need of nomenclature updating. Twentysix publications are considered. The earliest sampling record is from 1913 (?) and the most recent from 2002. This checklist compiled from the literature was complemented with primary data collected between August 2004 and July 2006, recent surveys of the surf-zone of 20 beaches located along the coast and of a mariculture farm at the Cocanha Beach, Caraguatatuba. The complete species list includes 572 taxa: most are diatoms (82%), seconded by dinoflagellates (16%), with a minor contribution of silicoflagellates, coccolithophorids, ebriideans and cyanobacteria. The most investigated areas were: Ubatuba, São Sebastião, Santos and Cananéia. The recent surveys have a broader spatial coverage. The objectives of the studies have changed over the years from purely taxonomic to process-oriented investigations. Therefore, the longest species lists and most first records for the area were published before the 1980's and later publications, even those in which cell counts were performed, mention only the most abundant/frequent species. Electron microscopy was used for the first time in the present surveys, and new records include 38 diatoms, 42 dinoflagellates, 1 silicoflagellate, 1 ebriidean and 2 cyanobacteria. The use and interpretation of this species list require the perception of some constraints. It is not our role to question the identification made by other researchers. On the other hand, the ability to sample, analyze and identify species has evolved over the years and some considerations in this regard are presented.
