Ocean Acidification

In the BMBF-funded joint project BIOACID (Biological Impacts of Ocean Acidification), which ran for three three-year funding periods and was coordinated by Ulf Riebesell, our working group investigated

• the sensitivity of physiological processes at the organism level
• the evolutionary adaptation potential
• the effects of organism reactions on trophic relationships
• the consequences of ecological changes for biogeochemical cycles

Methodologically, we used

• rate measurements with pure cultures
• long-term experiments over 2000 generations to clarify the evolutionary adaptation potential
• incubation experiments at the population level
• mesocosm experiments with a volume of 60,000 liters at the ecosystem level
