Joint Seminar: Ocean acidification: knowns, unknows, and perspectives

The growing evidence of potential biological impacts of ocean acidification affirms that this global change phenomenon may pose a serious threat to marine organisms and ecosystems. Despite a wealth of information on specific effects of acidification on the physiology of individual marine taxa, many uncertainties still remain. Because the majority of studies are based on single species experiments, little is presently known about possible impacts on natural communities, food webs and ecosystems. Moreover, few studies have addressed possible interacting effects of environmental changes occurring in parallel with ocean acidification, such as ocean warming and deoxygenation. Also practically unknown at present is the potential for evolutionary adaptation to ocean acidification. In my presentation I will outline the knowns and unknows in ocean acidification research and highlight a few case studies representing our current state of understanding of ocean acidification impacts.
