lakes and reservoirs. To test how different strains respond to changing carbon dioxide levels in water, Jef Huisman and his colleagues at the University of Amsterdam kept mixed populations
in the laboratory and aerated the water with bubbles containing low or elevated levels of CO2. In low CO2 conditions, strains whose carbon-uptake systems are efficient when carbon is limited
became dominant. When CO2 was elevated, however, strains that have systems with high uptake rates outcompeted the others. The team studied _Microcystis_ collected from Lake Kennemermeer in
the Netherlands and found that the abundance of each strain shifted with seasonal changes in CO2 availability. This is a preview of subscription content, access via your institution ACCESS
