Brown-led team offers first look at how bats land

PROVIDENCE, R.I. [Brown University] People have always been fascinated by bats, but the scope of that interest generally is limited to how bats fly and their bizarre habit of sleeping upside down. Until now, no one had studied how bats arrive at their daytime perches. A Brown University-led re...

Whispering bats are 100 times louder than previously thought

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 cou...

Why fruit-eating bats eat dirt

Dont eat the green parts of tomatoes, cut the green off the potatoes. Any child would know that eating these parts of vegetables is a bad idea. The reason behind this is that they contain secondary plant compounds which may have detrimental effects on the consumer. Each night, tropical fruit-ea...

Smithsonian researchers show major role of bats in plant protection

Researchers at the Smithsonian Tropical Research Institute report that bats significantly reduce insect abundance and damage on plants. In a lowland tropical rainforest in Panama, bats can consume roughly twice as many plant-eating insects as do birds. This landmark study in the journal Science is...

Birds, bats and insects hold secrets for aerospace engineers

ANN ARBOR, Mich.---Natural flyers like birds, bats and insects outperform man-made aircraft in aerobatics and efficiency. University of Michigan engineers are studying these animals as a step toward designing flapping-wing planes with wingspans smaller than a deck of playing cards. A Blackbird ...

Researchers studying how singing bats communicate

COLLEGE STATION, Oct. 18, 2007 Bats are the most vocal mammals other than humans, and understanding how they communicate during their nocturnal outings could lead to better treatments for human speech disorders, say researchers at Texas A&M University. Thousands of bats native to Central Texas...

Scientists tackle the mystery of white-nose syndrome in bats

KNOXVILLE -- The mysterious disease that has killed more than 90 percent of wintering bats in some caves and mines from Vermont to Virginia during the last three years has raised numerous questions about the nature of the disease and how to control it. Leading experts in the fields of bat physi...

A 'private bandwidth' for communication in bats: Evidence from insular horseshoe bats

Oxford August 13, 2007 - Do bats use their ultrasonic echolocation calls to recognise their own species" A new study in the Journal of Biogeography by Danilo Russo and colleagues suggests that this is certainly the case for horseshoe bats (Rhinolophidae). These bats find their way in the dark and...

Vampire bats recognise their prey's breathing

Vampire bats, the only mammals to feed exclusively on blood, including human blood, recognize their prey by the sound of its breathing. In a study published today in the open access journal BMC Biology, vampire bats of the species Desmodus rotondus could recognise recorded human breathing sounds mu...

Cultural transmission in bats: When listening for dinner, bats learn from their neighbors

In an exciting study that provides new understanding of how animals learn--and learn from each other--researchers have demonstrated that bats that use frog acoustic cues to find quality prey can rapidly learn these cues by observing other bats. While numerous examples are known of instances where p...

Birds and bats sow tropical seeds

Restoring the rich diversity of trees that once characterized expansive tracts of tropical rainforest gets a helping hand from native birds and bats. Just how big a role these winged gardeners play is a question ecologists from the University of Illinois at Chicago and several Latin American univer...

Vampire bats keep out of trouble by running

Although most people think of bats as stealthy mammals that flit about in the night sky, at least one species has evolved a terrestrial trot never before seen in bats, according to a recent Cornell University study. It's known that the common vampire bats of Central and South America behave much ...
