Climate change affects life on Earth in many ways. This thesis contributes to understanding these effects through the analysis of stable isotopes, which provide insights into the ecology of red knots. Experiments with captive birds showed how isotopes from food are incorporated into tissues, enabling reconstructions of diets and timing of migration ...
