-1 - BIOMECHANICAL AND STRUCTURAL MODELING OF HEARING IN BALEEN WHALES
Introduction Anthropogenic noise may be a major source of habitat degradation for cetaceans. To assess and mitigate the effects of noise pollution on marine mammals, we need information on how and what they hear. Although hearing in odontocetes, or toothed whales, is well studied, few data are avail...
