Listening in on manatees can determine population numbers
To successfully conserve and restore manatee populations, scientists need to know how many of them there are in a specific habitat. This isn’t always easy to find out, particularly in the Bocas del Toro province in Panama, where Antillean manatees live in turbid brackish waters, covered by thick aquatic vegetation.
Other methods, like aerial and sonar surveys, and infrared cameras, present logistical challenges and can be costly.
