COLLEGE PARK, Md., March 27, 2014 /PRNewswire-USNewswire/ -- Look up into the sky at dusk this spring and you're likely to see small groups of bats flitting here and there, gobbling up their insect meals in an intricately choreographed aerial dance. It's well known that echolocation calls keep the bats from hitting trees and each other. But now scientists have learned some bats emit another call: one that tells their comrades to "back off" from bugs they've claimed for themselves....

bats and light pollution
2014-03-11 10:22:41

Wiley These new findings were reported by scientists from the German Leibniz Institute for Zoo and Wildlife Research Berlin (IZW). The study – published in the British Ecological Society's Journal of Applied Ecology – is the first to show that seed-dispersing bats avoid feeding in light-polluted areas. Working in Costa Rica with Sowell's short-tailed bats (Carollia sowelli), Daniel Lewanzik from the IZW gave the bats a simple choice. He divided a flight cage into two compartments....

The tent-making bat Uroderma bilobatum

Brett Smith for redOrbit.com - Your Universe Online While scientists know that a superfamily of genes inside olfactory receptors is responsible for our sense of smell – we still don’t know the mechanism behind the interpretation of odor molecules into a particular smell. A new study published in the journal Molecular Biology and Evolution has found a distinct gene pattern in the olfactory receptors of fruit-eating bats – potentially shedding some light on the mechanism behind our...

Small Flying Vehicles, Complete with Flapping Wings, may Emerge from Study of Fruit Bats WASHINGTON, Feb. 19, 2014 /PRNewswire-USNewswire/ -- By exploring how creatures in nature are able to fly by flapping their wings, Virginia Tech researchers hope to apply that knowledge toward designing small flying vehicles known as "micro air vehicles" with flapping wings.

Building Better Aircraft Based On Bat Wing Motions
2014-02-18 12:57:54

[ Watch the Video: Bats Inspire Next-Gen Aircraft ] Lee Rannals for redOrbit.com - Your Universe Online Researchers are studying how bats flap their wings in hopes it will help in designing small flying vehicles in the future. The team studied how bats use their wings to manipulate the air around them and wrote about their findings in a paper published in the journal Physics of Fluids. Over 1,000 bat species have hand membrane wings in which their fingers are “webbed” and are...

Engineering Plus Evolutionary Analyses Used To Answer Natural Selection Questions
2014-01-24 14:45:08

University of Massachusetts at Amherst Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection, researchers report in the current issue of Evolution that the new tool opens a way of discovering evidence for selection for biomechanical function in very diverse organisms and of reconstructing skull shapes in long-extinct ancestral species. Evolutionary biologist Elizabeth Dumont and mechanical engineer Ian Grosse at the...

Ripple Effect Used By Bats When Hunting Frogs During Mating Season
2014-01-24 12:56:12

Brett Smith for redOrbit.com - Your Universe Online As male túngara frogs call from their puddles to attract females, they create ripples that spread across the water. According to researchers at the Smithsonian Tropical Research Institute (STRI) in Panama, these ripples are used by other male frogs to assess their competition – and also by bats looking for their next meal. If it sees a bat flying overhead, a male túngara will stop calling – yet ripples continue moving for several...

New Recording System Reveals Endangered Animals
2014-01-23 13:28:37

University of Southern Denmark Now biologists can get much more accurate information about endangered bats, birds and insects. A new recording system, developed at the University of Southern Denmark, has revealed many previously unknown and highly valuable details about bats. Gone are the days where biologists had to sit in tents for several days with binoculars and infrared cameras in order to register endangered animals.  A new monitoring system, which for two months has continuously...

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...

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....
