- Marine ecosystems face several environmental changes in the future. Rising atmospheric CO2 levels increase the ocean CO2 concentrations by a process known as ocean acidification. This is of great concern for marine organisms and yet we know very little about the combined effects of ocean acidification and other stressors such as spreading of oxygen depleted (hypoxic) areas. The Norway lobster, Nephrops norvegicus,is one of the commercially most important shellfish species in Europe. It is found on coastal soft bottom sediments that are subjected to periodic hypoxia. Hypoxia may in turn lead to release of manganese from the sediment, which is accumulated in benthic organisms. Here we investigated behavioral effects on N. norvegicus after long-term exposure to elevated CO2, at concentrations postulated for year 2100, but also the combinational effect of elevated CO2 and hypoxia and manganese. We show several behavioral disturbances, including effects on food recognition, food search and CO2 avoidance. Our results are compared with CO2 induced behavioral disturbances previous found in fish.
