Topic:Florida Manatee (Trichechus manatus latirostris) Hearing and Boat Collisions: Integration of Laboratory and Field Studies
Boat strikes are responsible for half of adult manatee mortality. Here we integrate research on the hearing capabilities of manatees under laboratory conditions with field investigations of manatee-boat interactions to assess our understanding of manatee-boat collisions. Laboratory studies have evaluated manatee hearing sensitivities,critical ratios, and ability to localize sound sources. These studies indicate that manatees should be able to detect boat noise. Evidence from field studies indicates that manatees change their behavior in response to close-approaching boats most of the time. We discuss environmental, acoustic, and behavioral factors that increase the likelihood of collisions and identify important directions for future research.
