Past research on dolphin echolocation has shown that dolphins can adaptively control the frequency and amplitude of echolocation clicks. The degree to which click production is controlled and the relationship between click variation and echolocation task remains uncertain. This thesis describes a research protocol for studying the adaptive control of dolphin echolocation. The protocol builds on past studies to investigate the manner in which the spectral characteristics of clicks and the overall number of clicks produce for a given task vary in relation to the type of task being performed.

Nine bottlenose dolphin (Tursiops truncatus) calves that stranded in Virginia in 1996 and 1997 died of severe blunt-force trauma. Injuries were concentrated on the head and chest and multiple rib fractures, lung lacerations, and soft tissue contusions were prominent. Skeletal and/or soft tissue trauma occurred bilaterally in all of the calves. One had a bite wound across the left mandible that exhibited deep punctures consistent with the tooth placement in an adult bottlenose dolphin. The lesions were not compatible with predation, boat strike, fisheries interactions, rough-surf injury, or blast injury. However, they were similar to traumatic injuries described in stranded …
