comprised populations that differ genetically in their response to the environment at spatial scales of around 600–800 km, undetected by microsatellite DNA variations. They caught cod from four populations within the Atlantic and looked at larval growth in the laboratory. Among all four populations, growth increased with food supply and temperature but the influence of changes in food and tempe...
