Abstract

Since Cabral arrival Brazilian coast passed by huge changes. Urbanization, agriculture and industrialization in coastal areas changed physiognomies and composition of shallow flora. Last decades ocean acidification (OA) and Ocean Warming (OW) appear as stressor that should have enormous impacts on marine coastal organisms across the globe, however, there are still many open questions regarding the responses that photoautotrophs will have.  Biological interactions between global and local stressors, as well phenotypic plasticity, expressed by morpho/physiological and ecological adaptations, represent questions that deserve major attention in South Atlantic.  Our group, from the Laboratory of  Phycology, Federal University of Santa Catarina (south of Brazil), manipulated multiple variables (CO2, temperature and local stressors) in laboratório, field and in marine mesocosm facilities in North and southern Brazil in order to test the magnitude of the effects of multiple stressors on the physiology of common photoautotrophs from shallow marine coastal ecosystems in Brazil. In this talk, I bring some case studies about the ecophysiological behavior of marine primary producers under threat of global change stressors.
