Do gray whales count calories? Comparing energetic values of gray whale prey across two different feeding grounds in the eastern North Pacific

Creator:

Hildebrand, Lisa, Bernard, Kim S., and Torres, Leigh G.

Abstract:

Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most...

Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:

Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.

Abstract:

Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...
