Variation in pup vocalisations and mother-pup behaviour between harp seal whelping patches: effects of climate or geography?
Harp seals breed in pack-ice, a substrate which can vary substantially between whelping patches depending on differing environmental and oceanographic conditions. This study demonstrates clear site differences in pup vocalizations and mother pup behaviour between Northeast (Greenland Sea) and Northw...
