Scientific experiments using animals frequently involve the marking of animals that artificially changes their phenotype. For instance, penguins with flipper bands have been used to study climate change. However, as Saraux et al. show, this banding reduces penguins’ survival rate. Consequently the study may mix up the effects of banding with other changes in penguin […]

Each prey species they feed on requires special hunting skills and there have been observational reports […]
