Tame behaviour, i.e. low wariness, in terrestrial island species is often attributed to low predation pressure. However, we know little about its physiological control and its flexibility in the face of predator introductions. Marine iguanas (Amblyrhynchus cristatus) on the Galapagos Islands are a good model to study the physiological correlates of low wariness. They have lived virtually without predation for 5-15 Myr until some populations were first confronted with feral cats and dogs some… CONTINUE READING
