copepod species* that dominate zooplankton in Arctic waters to carbon dioxide concentrations which are nearly ten times higher than those today. “We started our tests with the toughest living conditions. In [...] next research questions are, therefore: What do copepods eat if their favourite food, diatoms, has nearly vanished already when the animals wake up from their winter dormancy? Can they also live on significantly
