It’s the first study of seal stranding rates that takes into account genetics, as well as environmental and demographic factors like age and gender.  Duke research scientist David Johnston says that genetic fitness does not affect the rate of stranding.

Warmer temperatures in the North Atlantic over the last several decades have resulted in significantly higher mortality rates of baby harp seals. A new study out of Duke looked at satellite data of ice conditions in the Gulf of St Lawrence, a major breeding region and compared them to yearly reports of dead seal pups that washed up on shore. Lead researcher David Johnston is a scientist at the Duke University Marine Lab:


David Johnston:  These animals have evolved to take advantage of the advan tages of ephemeral surfaces like ice.
