Michael Harper for redOrbit.com — Your Universe Online Have you ever tried to tell the difference between 34 different bat species? Like a fingerprint or the specific pitch and timbre of a person´s voice can differentiate one human from another, so, too, can the subtleties in squeaks and squelches set one bat apart from the others. Now, a team of ecologists have built an echo-location tool which can identify specific bats based on their vocal signatures. The new tool,...

UK scientists will measure the effect on the marine environment and wildlife of devices that harness tide and wave energy using sonar technology that has, for the first time, been successfully deployed on the seabed. Renewable energy from tidal currents can be generated using turbines in the tidal flow, and wave energy can be captured in a number of different ways. FLOWBEC (Flow and Benthic Ecology 4D) is a three-year, £1.2 million project that brings together a consortium of...
