Sentences with phrase «emit echolocation»

Microbats, the group of bats that emit echolocation signals from the larynx, came under close scrutiny because, surprisingly, some molecular studies divided them into two groups that diverged long ago, suggesting that echolocation evolved twice.

One way to avoid being eaten was to emit echolocation sounds that were difficult for killer whales to detect — thus an ability favored by evolution, «concludes Lee Miller and Magnus Wahlberg in their research article.

But why do many species of porpoises and other small toothed whales emit echolocation sounds at about 130 kHz?

Not exact matches

The detector picks up the echolocation calls emitted by bats and translates it to a frequency the human ear can hear.

The Pallas long - tongues bats (Glossophaga soricina) are an important pollinator in Central and South America and belong to a group of bats that are often called «whispering bats» because many emit relatively quiet echolocation calls to forage within dense vegetation.

Although the majority of those that use echolocation — emitting sound waves that bounce off objects — to hunt are usually lumped into one group, a new study suggests that some belong in a separate category.

These mammals make human speech look simple: In a behavior called echolocation, a bat must coordinate its nose, mouth, ears, and larynx to emit and receive calls, all the while executing flight maneuvers guided in part by these signals.

Boom Boxes Ultrasonic «boom boxes» that emit continuous high - frequency sounds from 20 to 100 kilohertz deter bats from getting too close to turbines by interfering with their echolocation.

As the bats search for a place to roost, the structure acts as an acoustic flag, bouncing back the ultrasonic calls the bats emit to navigate (a process known as echolocation) and waving the bats down to a comfortable home.

Since its discovery, researchers have found that the gene plays a role in the development of language (ScienceNOW, 14 August 2002), that mice need the gene to emit characteristic ultrasonic sounds (ScienceNOW, 21 June 2005), and that it plays a role in bat echolocation (ScienceNOW, 19 September).

Bats have an incredible ability to navigate using echolocation, weaving their way around obstacles and finding prey based on the bouncing around of the sounds they emit.
