Penguins, whales and many fish rely on krill, a small crustacean, as a staple part of their diets. This project uses 30 years of data on penguin population sizes and breeding success from field studies in Antarctica to evaluate the relationship between krill abundance and penguin reproduction and survival on the Antarctic Peninsula.
