Individual dolphin calls used to estimate population size and movement

An international team of scientists has succeeded in using the signature whistles of individual bottlenose dolphins to estimate the size of the population and track their movement.

The research, led by the University of Plymouth and Stellenbosch University, marks the first time that acoustic monitoring has been used in place of photographs to generate abundance estimates of dolphin populations.

Writing in the Journal of Mammalogy, researchers say they are excited by the positive results yielded by the method, as the number of dolphins estimated was almost exactly the same as estimated through the more traditional photographic mark-recapture method. MORE
