Abstract
There is considerable interest in documenting diets and trophic interactions within and among marine mammal species since such information provides critical insight into their basic ecology, including their movements, nutrition, and exposure to contaminants (Hobson 1999, Ben-David and Flaherty 2012, Foote et al. 2012). Variation in diets and use of habitats among individuals and how individual dietary patterns may change seasonally are also intricately linked to movements and behaviors of regional populations. Understanding such intricacies within populations is crucial to the conservation and management of marine mammals species.
