Israeli scientists fitted fruit bats with the world's smallest GPS devices GPS technology can make our travels easier and more efficient. But for many animals, the ability to successfully navigate a landscape is not just a matter of convenience "“ their very survival depends on it. Egyptian fruit bats, for instance, fly dozens of kilometers each night to feed on specific fruit trees, making the return trip the same night. To understand how the bats locate individual trees night after...

In a paper published recently in the journal Science, researchers at Brown University and from the Republic of Georgia have learned how bats can home in on a target, virtually dismissing other objects in their midst. The trick lies in their neurons: Bats can separate a cavalcade of echoes returning from their sonar blasts by distinguishing changes in amplitude "” the intensity of the sound "” between different parts of each echo within 1.5 decibels, to decide whether the object is...

Scientists have found a rainforest vine that has evolved dish-shaped leaves to attract the bats that pollinate it. Tests found that the leaves were supremely efficient at bouncing back the sound pulses the flying mammals used to navigate. The bats were found to be able to locate the plant when the leaves were present twice as quickly as when they were removed. This study is the first to find a plant with "specialized acoustic features" to help bat pollinators find them using sound. Bats...

The researchers discovered that a rainforest vine, pollinated by bats, has evolved dish-shaped leaves with such conspicuous echoes that nectar-feeding bats can find its flowers twice as fast by echolocation. The study is published today in Science. While it is well known that the bright colours of flowers serve to attract visually-guided pollinators such as bees and birds, little research has been done to see whether plants which rely on echolocating bats for pollination and seed dispersal...

University of Calgary research finds urban life not healthy for bats In the treeless, flat Prairie, you'd think a city would provide a good home for bats who like to snuggle up and roost in trees and buildings. But researchers at the University of Calgary made the surprising discovery that the urban landscape is far from ideal for these animals. "I was really surprised," says Dr. Joanna Coleman, a sessional lecturer and recent PhD graduate in biological sciences at the University of Calgary...

Echolocation in bats and dolphins is well known. Bursts of sounds are created and the echoes that bounce back are used to locate and detect objects in the environment. What is less well known is that people can echolocate, too. Blind people have been known to learn to make clicks with their mouths and to use the returning echoes from those clicks to sense their surroundings. Some of these people are so adept at echolocation that they can use this skill to go mountain biking, play basketball,...

Using a method based on geographic positioning systems that allowed them to characterize the topography of the bats' molars in a way similar to how geographers characterize mountain surfaces, the researchers calculated a measure of dental complexity that reflects how "rugged" the surface of the tooth is. They illustrate a trend from relative simplicity of the shearing molars in insect eaters and omnivores to high complexity of the crushing molars in fruit eaters. Working with field-collected...

(Ivanhoe Newswire) --Tired of the old pick up line "In a room full of people all I hear is you?"  Well, research reveals that may be true. A study found that brains of bats tell some neurons to 'shush' and others to 'yell louder' in order for key sounds to be heard above background noise"”a process that may be working in humans as well. "Some neurons seemed to know to yell louder to report communication sounds over the presence of background noise," Bridget Queenan, a doctoral...

Greater mouse-eared bat, Myotis myotis
2013-10-11 08:16:26

The greater mouse-eared bat is primarily found throughout Europe. It weighs about 1.6 ounces, has a wingspan of 14-18 inches and its body is 3-3.5 inches long. The Greater mouse-eared bat has a medium brown upper-body and a greyish belly. This species of bat does not use echolocation for hunting but rather catches its prey from the ground and water surfaces, a process known as gleaning. It finds its prey by listening for the noises that these animals usually make. Its menu consists of...

Brandt’s Bat, Myitus brandtii
2013-10-11 08:07:41

The Brandt’s bat has a large population in northwest of England but is endangered in Austria. The Brandt’s Bat has shaggy brown fur with a pale grey belly. This bat is not a large bat and weighs less than half an ounce and measures up to two inches long. Its wingspan is more than triple its body length at 7.5 to 9.5 inches. Brandt’s bat eats only insects (insectivorous) and is not blind. However, echolocation is used for “night-vision,” so that while hunting at night it does...

Lesser mouse-eared bat, Myotis blythii
2013-09-27 10:50:24

Populations have been found in southern Europe, southern central Europe and southwestern Asia. The lesser mouse-eared bat is a very social species therefore they travel and remain in groups rather than individually. These groups can be as large as 500 bats and could be mixed with the greater mouse-eared bat. Their feeding habitats are scrub areas, grasslands, farmland, and some gardens. It eats grass crickets and cockchafers. These insects are hunted by the lesser mouse-eared bat while...

Azores noctule, Nyctalus azoreum
2013-09-18 15:49:27

This species is a red listed endangered species. The Azores noctule bat lives in the dry forests of the Portugal islands known as the Azores. The endangerment of this species is directly connected to the loss of their habitat caused my human growth. The three primary habitats are haollow trees, caves, and buildings. The Azores noctule bat is a subspecies to the lesser noctule and the genetic differences are very minimal. The Azores bat is smaller in weight as well as length. The Azores also...

Greater noctule bat, Nyctalus lasiopterus
2013-09-18 15:41:29

The greater noctule bat is found in Europe, West Asia, and North Africa. This species of bat is a tree-dweller and roosts in high, hollow, deciduous trees year round. However, the greater noctule bat will roost in pine trees if there is a shortage of hollow trees. This bat chooses a roosting spot by characteristics of a tree more than type of tree; such as, decaying and high off the ground. Females will be found primarily in warmer climates that are ideal for fetal growth and milk production....
