Breeding synchrony and predator specialization: A test of the predator swamping hypothesis in seabirds
Abstract Reproductive synchrony is a widespread phenomenon that is predicted to be adaptive for prey with specialist predators but not for those with generalist ones. I tested this prediction in three polar seabird species characterized by different levels of predator specialization. In the Antarcti...
