Cyanobacteria are thriving in many aquatic systems and have recently increased in abundance.To shed light on the reasons for and the consequences of their success we will carry out resurrection, evolutionary and model experiments. We will 1) investigate whether cyanobacteria have evolved to warmer environmental conditions, 2) quantify their evolutionary potential to cope with even higher temperatures and 3) assess their potential to dominate future phytoplankton communities in a seasonally-varying and overall warmer environment by taking into account ecosystem and biogeochemical feedback mechanisms. This study is the basis for improved climate projections, that include the evolutionary response of key organisms.
