Bats Rely On Vision To Navigate, Echolocation To Catch Insects: Study
2013-12-13 07:34:50

April Flowers for redOrbit.com - Your Universe Online\ Bats rule the night skies, using the power of echolocation, or reflected sound. More than 1,000 species of echolocating bats exist, compared to just 80 species of nocturnal non-echolocating birds. It seems that normal vision works in tandem with echolocation to give bats an evolutionary edge, however, no one knows exactly how. A new study, led by Arjan Boonman and Yossi Yovel of Tel Aviv University's Department of Zoology, suggests...

Nectar Bat Uses Stealthy Moves To Catch Its Evening Dinner
2013-12-12 15:39:25

Lee Rannals for redOrbit.com - Your Universe Online New research shows the Pallas long-tongued bat is a very stealthy predator when it comes to catching insects. Previously, scientists believed the nectar-feeding bat ate insects in passing, but the latest research shows it targets its moving prey with stealthy precision. The team proved for the first time that the Pallas long-tongued bat uses a stealthier form of echolocation. Echolocation is a physical trait that involves the...

Echolocation - With Practice, Anyone Can Learn It
2013-08-30 04:23:17

redOrbit Staff & Wire Reports - Your Universe Online Humans can learn to use echolocation to navigate and to find objects, according to new research appearing in the latest edition of the biology journal Proceedings of the Royal Society B. Professor Lutz Wiegrebe of the Ludwig-Maximilians-Universitaet (LMU) Department of Neurobiology and colleagues have now shown how people can acquire the capacity for echolocation, though they emphasize doing so takes a considerable amount of time...

Moths Jam Bat Echolocation Systems

Brett Smith for redOrbit.com - Your Universe Online For years, the military has used radio signals to jam an enemy's radar and a new study in the journal Biology Letters suggests hawk moths use the same technique to evade predation by bats. According to the study's authors from the University of Florida, hawk moths emit sonic pulses from their genitals in response to the high-frequency echolocation that bats produce to locate prey. "This is just the first step toward understanding a...

Blind People Can Learn To Use Their Inner Bat
2013-05-21 05:51:25

April Flowers for redOrbit.com - Your Universe Online Researchers have known for a long time that blind and visually impaired people rely on other senses. A new study led by the University of Southampton, however, now shows that they have the potential to use echolocation, similar to that of bats and dolphins, to determine the location of an object. The researchers examined how hearing, particularly the hearing of echoes, could help blind people with spatial awareness and navigation....

A new study reveals that the way fruit bats use biosonar to 'see' their surroundings is significantly more advanced than first thought. The study, published September 13 in the online, open access journal PLoS Biology, examines Egyptian fruit bats (Rousettus aegyptiacus), which use echolocation to orient inside their caves and to find fruit hidden in the branches of trees. Their high-frequency clicks form a sonar beam that spreads across a fan-shaped area, and the returning echoes allow them...

Bats' remarkable ability to "Ëœsee' in the dark uses the echoes from their own calls to decipher the shape of their dark surroundings. This process, known as echolocation, allows bats to perceive their surroundings in great detail, detecting insect prey or identifying threatening predators, and is a skill that engineers are hoping to replicate. A team of British researchers has worked with six adult Egyptian fruit bats from Tropical World in Leeds to record and recreate their...

German scientists have discovered bats can use echolocation in identifying characteristics of other individual bats' voices to recognize each other. Researchers from the University of Tuebingen and the University of Applied Sciences in Konstanz said they first tested the ability of four greater mouse-eared bats to distinguish between the echolocation calls of other bats. After observing the bats learned to discriminate the voices of other bats, then they programmed a computer model that...

Bats can use the characteristics of other bats' voices to recognize each other, according to a study by researchers from the University of Tuebingen, Germany and the University of Applied Sciences in Konstanz, Germany. The study, published June 5 in the open-access journal PLoS Computational Biology, explains how bats use echolocation for more than just spatial knowledge.The researchers first tested the ability of four greater mouse-eared bats to distinguish between the echolocation calls of...

Annemarie Surlykke from the University of Southern Denmark is fascinated by echolocation. She really wants to know how it works. Surlykke equates the ultrasound cries that bats use for echolocation with the beam of light from a torch: you won't see much with the light from a small bulb but you could see several hundred meters with a powerful beam. Surlykke explains that it's the same with echolocating bats. Some have big powerful calls for perception over a long range, while others are said...
