Image 1 - Bats Can Change Ear Shape To Make Their Hearing More Flexible
2011-11-15 05:24:09

"Certain bats can deform the shapes of their ears in a way that changes the animal's ultrasonic hearing pattern. Within just one tenth of a second, these bats are able to change their outer ear shapes from one extreme configuration to another," said Rolf Müller, associate professor of mechanical engineering at Virginia Tech. Müller and his students wrote a paper on their work that is appearing this week in Physical Review Letters, a prestigious peer-reviewed...

Researcher Links Fungus To Dropping Bat Population
2011-10-31 13:21:51

A University of Tennessee researcher helped confirm the link between the fungus Geomyces destructans and the dropping bat population. Over a million bats were killed in North American in 2006, and little has been done to try and save them due to lack of evidence for the alleged killer. However, a new study has discovered that the fungus Geomyces destructans is the agent of White-noise Syndrome (WNS), which is the fungal disease decimating the bat population. The fungus has been...

New virus could be the first filovirus to cause disease in bats A team of international researchers has discovered a new Ebola-like virus — Lloviu virus -- in bats from northern Spain. Lloviu virus is the first known filovirus native to Europe, they report in a study published in the journal PLOS Pathogens on Octobr 20th. The study was a collaboration among scientists at the Center for Infection and Immunity (CII) at Columbia University's Mailman School of Public Health, the...

Bats Have Fastest Known Mammal Muscle
2011-09-30 05:04:01

Bats derive their ability to use echolocation, the bouncing of sound waves off objects to produce an accurate representation of the environment in total darkness, from so-called “superfast” muscles, researchers reported in latest issue of the journal Science. These superfast muscles, which are located in the bats´ larynx, are a physical trait never before seen in mammals, and allow the bate to make a rapid series of calls as they home in on their prey.   They...

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...

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...

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....
