Multi-year patterns in testosterone, cortisol and corticosterone in baleen from adult males of three whale species
Baleen from three adult male whales (North Atlantic right, bowhead and blue) contains regularly spaced areas of high testosterone content suggestive of annual testosterone cycles. Patterns in glucocorticoids (cortisol and corticosterone) show potential relationships with breeding-related stress as w...

Summary: | Baleen from three adult male whales (North Atlantic right, bowhead and blue) contains regularly spaced areas of high testosterone content suggestive of annual testosterone cycles. Patterns in glucocorticoids (cortisol and corticosterone) show potential relationships with breeding-related stress as well as with entanglement in fishing gear and possible disease episodes. |
