When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by ...

Imagine searching for a gemstone in a dark cave: You use a flashlight, looking for a rainbow-colored glint in the darkness.

What do bats, dolphins, shrews, and whales have in common? Echolocation! Echolocation is the ability to use sound to navigate. Many animals, and even some humans, are able to use sounds in order to ...

Bats live in a world of sounds. They use vocalizations both to communicate with their conspecifics and for navigation. For the latter, they emit sounds in the ultrasonic range, which echo and enable ...

Researchers played simulated bat echolocation calls in the laboratory and found that egg-bearing A. nigrisigna stopped flying when exposed to high pulse repetition rates. This behavior could be ...

Bats are nocturnal hunters and use echolocation to orient themselves by emitting high-frequency ultrasonic sounds in rapid succession and evaluating the calls' reflections. Yet, they have retained a ...

For many nocturnal moths, hearing sound waves is a matter of survival in the night sky. Their ability to detect ultrasonic calls emitted by bats determines whether they escape or become prey. This ...

Sound plays an important role for many animals, helping them navigate and hunt. Echolocation is the ability of animals like bats and dolphins to locate objects by emitting sound waves and interpreting ...

Bats, as the main predator of night-flying insects, create a selective pressure that has led many of their prey to evolve an early warning system of sorts: ears uniquely tuned to high-frequency bat ...
