Abstract

Coastal upwelling produce contrasts in the pelagic environment due to the increase of the primary production, the generation of temperature oscillations and the variation of the patterns of the surface currents with important ecological implications to the coastal benthic communities. This process generates spatio-temporal variations of larval supply, as well as variations of the reproductive output of benthic populations. Due to the oceanographic dynamic at this region, we will study the effects of wave impact, emersion, temperature and Chl-a concentration on the spatio-temporal variability of both reproductive output and recruitment, and the relationship between them along the east Coast of Ilha Bela. Barnacles and bivalves will be used as biological models to describe the desired processes. The observations will be conduced biweekly for one year, using integrative sampling methods. The relationship among those oceanographic variables and recruitment and reproductive output will also be investigated. We believe that this study will contribute to a better comprehension of the relationship between recruitment and reproductive output at the study area, and it will generate spatio-temporal integrated data which could be used in ecological modeling.
