1. Produção secundária e aspectos reprodutivos de copépodes pelágicos ao largo de Ubatuba (SP, Brasil) / Secondary production and reproductive aspects of pelagic copepods off Ubatuba (São Paulo, Brazil)
The present study evaluates how the pelagic copepod community structure and production from the inner shelf off Ubatuba (SP, Brazil) responded to environmental variability from July 2005 to June 2008. During these three years copepod secondary production was studied by the application of growth empirical models and weight-specific growth estimates obtained t

2. Fluctuating silicate:nitrate ratios and coastal plankton food webs
Marine diatoms require dissolved silicate to form an external shell, and their growth becomes Si-limited when the atomic ratio of silicate to dissolved inorganic nitrogen (Si:DIN) approaches 1:1, also known as the “Redfield ratio.” Fundamental changes in the diatom-to-zooplankton-to-higher trophic level food web should occur when this ratio falls below 1
