Study: Baltic Sea fish switch to lean diets when water temperatures rise. Small crustaceans, brittle stars, worms and molluscs serve as quickly available energy sources.
In the long term, the fish are less able to cover their energy needs than with larger, higher-calorie prey. The fish's adapted diet could therefore contribute to increased species extinction in times of climate change. Findings also apply to other animal groups, according to the researchers. lki.com.
