Geographic Differences in Blainville’s Beaked Whale (Mesoplodon densirostris) Echolocation Clicks

April 01, 2023

We use acoustic recordings collected over broad time and space scales to investigate whether global variability in echolocation frequency could make clear population structure in Blainville's beaked whale.

Understanding cetacean species' distributions and population structure over space and time is necessary for effective conservation and management. Geographic differences in acoustic signals may provide a line of evidence for population-level discrimination in some cetacean species.
