Bat vocal communication encompasses a diverse array of acoustic signals ranging from echolocation pulses that facilitate spatial mapping to complex social calls used in foraging, mating, and ...

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 ...

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 ...
