In the Azores archipelago we try to discover why devil rays gather around Princess Alice Sea Mountain in large numbers every summer. In northeast Turkey, we track bears in an overcrowded forest and learn that some have taken to feeding from the local rubbish dump. In France we join scientists working to prove that guardian dogs can effectively protect flocks of sheep from wolves.
