Captive and free‐living red knots Calidris canutus exhibit differences in non‐induced immunity that suggest different immune strategies in different environments
Experiments on captive animals, in which conditions can be controlled, are useful for examining complex biological phenomena such as immune function. Such experiments have increased our understanding of immune responses in the context of trade‐offs and pathogen pressure. However, few studies have ex...
