The rapid increase in coastal urbanization is a major threat to global biodiversity and ecosystem functioning. The abundance, composition and distribution of species has been modified with the urban sprawl, which has contributed to the loss of local biodiversity, introduction of non-native species and changes in the biological processes of communities. A major issue associated with urbanization is the contamination of coastal waters. The increase load of pollutants is one the main factors that has been associated with changes in the structure of benthic communities. However, there is a lack of knowledge on the interactive effects of stressors, even though, in natural communities, stressors rarely act alone. Thus, understanding the effects of multiple stressors on benthic communities and their effects on ecosystem functioning is key to inform decision makers on effective management strategies to prevent or reduce anthropogenic impacts on coastal systems to maintain their current ecosystem functioning and services. Rocky shores are the important coastal ecosystems in Brazil and in the world. This ecosystem supports a high diversity of species and provides numerous goods and services to humans. Considering the ecological and economical value of rocky shores and the current threat of coastal urbanization to this system, this project aims to: 1) indentify environmental stressors of rocky shores in natural and urbanized areas; 2) evaluate the 2a) abundance and distribution patterns on benthic communities in natural and urbanized areas, and 2b) their ecological functions and potential processes driving those patterns; and 3) investigate the effects of multiple stressors on benthic community by field experimental manipulations.
