In the dark world of the underwater ocean, whales need to locate their prey accurately and quickly. In low-vision conditions whales use echolocation to find fish swimming nearby, and now it has been discovered that they can focus their acoustical “vision” to accurately located slightly differing objects. For this study, Laura Kloepper from the University of Hawaii and her her PhD supervisor, Paul Nachtigall, utilized the help of Kina the False Killer Whale, a species related to...

False killer whales focus echolocation clicks Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. Laura Kloepper from the University of Hawaii, USA, explains that odontocetes produce their distinctive echolocation clicks in nasal structures in the forehead and broadcast them through a fat-filled acoustic lens, called the melon. 'Studies by other people showed...

Pacific Southwest Research Station/USDA Forest Service Science that makes a difference... An interactive tool developed by researchers from the USDA Forest Service´s Pacific Southwest Research Station (PSW) will help wind energy facility operators make informed decisions on efficient ways to reduce impacts on migratory bats. Fatalities of migratory bats at wind energy facilities have become a frequent occurrence. Bat migration patterns are poorly understood and the relationship...

New research reveals a right-hemispheric bias in bats when it comes to tackling navigation and a left-hemispheric advantage for communication Imagine listening to music while carrying on a conversation with friends. This type of multi-tasking is fairly easy to do, right? That's because our brains efficiently and effectively separate the auditory signals — music to the right side; conversation to the left. But what researchers have not been able to do in humans or animals is to see a...
