O plancton do rio Maria Rodrigues (Cananéia): I. Diatomáceas e Dinoflagelados

J. Paiva Carvalho

Resumo

The author studies seventeen surface level samples of Diatoms and Dinoflagellates collected between June 7 and October 28, 1949, by the São Paulo Oceanographic Institute, on the southern inshore region ol São Paulo State, Brazil. Thirty-two species of diatoms distributed among twenty-four genera were present in the samples collected. Neritic forms of northerly and southerly temperate habitats predominated, varying very little from those found commonly in the open ocean. Coscinodiscus excentricus and C. radiatus were the most prominent species. Chaetoceros curvisetum, Coscinodiscus grani, Thalassionema nitzschioides and Thalassiotrix frauenfeldii occurred in very large numbers in the samples. Certain regions are shown to be consistently more productive than others at the surface level. The species of diatoms represented throughout .the region were cosmopolitan; in character. Dinoflagellate population was represented by 8 species distributed, among 3 genera, but at no time did they occur in large numbers.

SUMMARY

The author studies seventeen surface level samples of Diatoms and Dinoflagellates collected between June 7 and October 28, 1949, by the São Paulo Oceanographic Institute, on the southern inshore region ol São Paulo State, Brazil.

Thirty-two species of diatoms distributed among twenty-four genera were present in the samples collected. Neritic forms of northerly and southerly temperate habitats predominated, varying very little from those found commonly in the open ocean.

Coscinodiscus excentricus and C. radiatus were the most prominent species. Chaetoceros curvisetum, Coscinodiscus grani, Thalassionema nitzschioides and Thalassiotrix frauenfeldii occurred in very large numbers in the samples.

Certain regions are shown to be consistently more productive than others at the surface level. The species of diatoms represented throughout .the region were cosmopolitan; in character.

Dinoflagellate population was represented by 8 species distributed, among 3 genera, but at no time did they occur in large numbers.
