The effects of nitrogen and phosphorus enrichments on phytoplankton in the region of Ubatuba (Lat. 23º30'S - Long. 45º06'W), Brazil

Abstract: (1968).The enrichments with surface waters reveal that nitrogen may be the major limi ting factor for phytop lankton biomass -6 en6U Liebig.

“…The Ubatuba region on the northern coast of São Paulo State-Brazil has been studied with relation to the phytoplankton and the primary production specially in coastal stations (Kutner, 1961;Tundisi et ai., 1978;Sassi, 1978;Kutner & Sassi, 1979;Sassi & Kutner, 1982;Oliveira, 1980;Teixeira & Tundisi, 1981;Teixeira, 1973;Perazza, 1982;Teixeira & Gaeta, 1990;Gaeta et ai., 1990); and in the shelf by Soares (1983) and Susini-Zilmanri (1990). Available data on environmental forcing in this region is restricted to surface sampling at a fixed station inside the Flamengo Bay, a well protected environment under the peculiar hydrodynamic mechanisms ofvery shallow waters (Teixeira, 1986).…”

“…Para alguns autores, o fósforo é o nutriente que controla o crescimento do fitoplâncton. Teixeira & Tundisi (1981), em trabalho realizado na região de Ubatuba, São Paulo, relatam que a adição de somente nitrogênio estimula o crescimento do fitoplâncton em termos de clorofila a enquanto que a adição somente de fósforo não resulta em diferentes crescimento, já a adição de nitrogênio e fósforo pode produzir um acentuado aumento da clorofila a. Aidar et al (1993), também mencionam sobre a limitação do nitrogênio para a biomassa fitoplanctônica na plataforma continental de Ubatuba, São Paulo.…”

“…The Ubatuba region is referred to as an oligo-mesotrophic system, limited mainly by inorganic nitrogen sources (Teixeira, 1973(Teixeira, , 1979Teixeira & Tundisi, 1981;Braga, 1989). Phosphorus limitation is attenuated in relation to that of nitrogen (Teixeira & Tundisi, op.…”
