Abstract

The effects of climate change on the world`s oceans are not limited to changes in carbonate chemistry but other parameters such as temperature, salinity and environmental distribution of chemical toxicants are also expected to change, especially in coastal areas. It is known that organisms have strategies to acclimate or even adapt to ocean acidification, however, whether this adaptation is extended when other stressors act jointly is not yet well understood. In this study the interaction of ocean acidification and the metals Copper and Zinc will be evaluated by performing experiments with the mussel Mytilus californianus. Toxic responses of organisms collected from two sites with different pH fluctuation will be compared in order to understand the role of local adaptation on this interaction. The results of this research will be important to give new insight on the extend of adaptation strategies of organisms to ocean acidification when metal contamination is acting as co-stressor. (AU)
