#Flying foxes (Actually Bats) on Remote Island Studied for First time Flying foxes? Not really foxes. They're actually bats (and one of those animals with a pretty misleading name.
Flying foxes are the largest bats On earth and consist of more than 60 species that live throughout remote islands of the Indian
 Pteropus pelagicus a relatively small species of flying fox with a wingspan of about 2 feet (61 centimeters) inhabits the western Pacific Mortlock Islands within the Federated States of Micronesia.

The team also found that the bats breed year-round on the islands which separates them from most other flying fox species
Most flying foxes are seasonal in breeding patterns and maybe give birth to young over a couple month period Wiles said.
Some cultures hunt flying foxes and consider them a delicacy but residents of the Mortlock Islands do not generally hunt the animals the researchers say.
There are about 1200 species of bats in the world 20 percent of all known mammal species. The largest bat is the flying fox with a wingspan of six feet the smallest is the bumblebee bat that weighs less than a penny.
Two-thirds of bat species feed on insects and other small prey. Many bats are on nighttime pest patrol.
One Mexican free-tailed bat can eat about 1000 mosquitoes per hour. The large colony of 30 million bats in Bracken Cave in Texas consumes about 250 tons of insects every night.
Just 150 big brown bats can eat 33 million root worm pests. Without bats there would be more pests
Other bat species feed on flowers and fruits acting act as pollinators and seed dispersers especially in deserts and rain forests.
There also would be no tequila the agave plant from which tequila is made depends on the Mexican long-tongued bat to pollinate it.

megabats and microbats. Megabats (formally bats in the Megachiroptera suborder) include flying foxes and Old world fruit bats.
They tend to be larger than microbats (Microchiroptera suborder) but some microbats are actually larger than some megabats.
Flying foxes (Genus pteropus) are the largest bats. Some species have wingspans of 5 to 6 feet (1. 5 to 1. 8 meters)
and weigh up to 2. 2 lbs. 998 grams) according to the Oakland Zoo. One of the smallest megabats the long-tongued fruit bat (Macroglossus minimus) has a wingspan of only 10 inches (25.4 centimeters) according to the Smithsonian Institution.
This bat weighs about half an ounce (14 g). Among microbats the largest species is the false vampire or spectral bat (Vampyrum spectrum) with a wingspan of up to 40 inches (1 meter.
It weighs 5 to 6. 7 ounces (145 to 190 g). The smallest bat is the bumblebee bat according to the University of Michigan Museum of Zoology.
It grows to only about 1. 25 inches long (3 cm) and weighs about 2 grams (0. 07 ounces).
Bats live all over the world except for some islands and the Arctic and Antarctica. They mostly prefer warmer areas that are closer to the equator
In this short-term form of hibernation a bat reduces its metabolic rate lowers its body temperature and slows its breathing and heart rate.
and leaves though it depends on the type of bat. Megabats usually eat fruits and microbats generally eat insects.
The Malayan flying fox has a big appetite. It can eat half its body weight every day. The vampire bat outdoes even that though eating twice its weight in one day.
The brown bat can eat up to 1000 small insects in an hour according to the Defenders of Wildlife organization.
Some bats will squeeze fruits in their mouths and drink the juices. Vampire bats like a juice of a different type though.
They do indeed drink blood mainly from cattle and deer but they don't suck blood like the legends say Rather they make A v-shaped cut and then lick up the blood according to the San diego Zoo.
Bats have some unique mating behaviors not seen in other animals. Male and female bats meet in hibernation sites called hibernacula where they breed.

#Culling vampire bats to stem rabies in Latin america can backfireculling vampire bat colonies to stem the transmission of rabies in Latin america does little to slow the spread of the virus
Vampire bats transmit rabies virus throughout Latin america causing thousands of livestock deaths each year as well as occasional human fatalities.
since the 1960s in attempts to control vampire bat populations but those culling efforts have failed generally.
Last year a team of U-M researchers and their University of Georgia colleagues reported the results of a long-term vampire bat field study in Peru.
and data from infection studies using captive vampire bats to show that culling has minimal effect on containing the virus
The findings suggest that geographic coordination of vampire bat control efforts in Latin america--taking into account the interconnectedness of seemingly isolated colonies--might reduce transmission to humans and domestic animals.
The team's new paper scheduled for online publication in the Proceedings of the National Academy of Sciences on Dec 2 also establishes that rabies is usually not lethal among vampire bats.
In the paper last year we demonstrated that bat colony size wasn't a predictor of rabies prevalence
Developing effective control strategies for vampire bat-transmitted rabies virus in Latin america requires an understanding of the mechanisms that have allowed the highly virulent pathogen to persist
Then they tested the models against data from the University of Georgia-led field study of rabies exposures in wild vampire bat colonies across Peru.
That study tracked rabies exposures in individually marked Desmodus rotundus vampire bats from 17 colonies in four regions of Peru between 2007 and 2010 and yielded the most complete dataset on rabies exposure patterns ever collected for any bat
and the most successful models demonstrated that a single isolated vampire bat colony cannot maintain the rabies virus over time Frequent movement of infectious bats between colonies is needed to keep the rabies virus at levels consistent with the field observations.
The critical role of immigration between bat colonies predicted by our analysis indicates that current culling practices often reactive to outbreaks in livestock
or haphazardly implemented are unlikely to eliminate VBRV (vampire bat-transmitted rabies virus) the researchers said. While programs targeting specific colonies may limit local spillover from bats to humans
or domestic animals regional viral persistence will likely remain unaffected due to high connectivity between bat colonies Rohani said.
The bat study's other main finding is that the vast majority of rabies virus exposures among vampire bats--in
which an infectious bat bites a susceptible individual--are nonlethal and actually immunize the bitten bat
thus helping to prevent colony extinction and sustain the virus. The probability of a vampire bat developing a lethal infection upon exposure to rabies is around 10 percent much lower than the 50-to-90 percent mortality rate seen in previous experimental challenges studies that involved inoculating vampire bats with rabies virus
according to the researchers In Latin america coordinated efforts to eliminate human rabies transmitted by dogs began in 1983 and led to a roughly 90 percent reduction in human and canine rabies according to the U s. Centers for Disease Control and Prevention.
Since 2000 vampire bats have been the leading cause of human rabies there especially in remote areas of the Amazon region in Peru Ecuador and Brazil according to the CDC.
The combination of large vampire bat populations and frequent contact with livestock contributes to losses of about $30 million annually in Latin american livestock mortality Of more than 1200 species of bats worldwide only three are vampires
and all three live in Latin america according to Bat Conservation International. Two of the species feed primarily on the blood of birds
and one--the common vampire bat D. rotundus--prefers mammals especially livestock. Common vampire bats hunt only when it is fully dark
and listen for the regular breathing sounds of sleeping mammals which serve as their main food source.
Once a target is located the bat lands and approaches it on the ground. Vampire bats use heat sensors on their nose to locate warm spots where blood flows through vessels near the skin's surface.
They use razor-sharp upper incisors to create small wounds. An enzyme in the saliva prevents clotting as the bat feeds
and a specialized groove in the tongue keeps blood flowing without the need for sucking
Movies notwithstanding vampire bats do not suck blood. They lap it like kittens according Bat Conservation International.
Worldwide more than 55000 people die of rabies each year according to the World health organization. More than 95 percent of the human deaths occur in Asia
They did however come across additional evidence that the U s. strains share several genetic features with a bat coronavirus--findings which point to an evolutionary origin from bats and the potential for cross-species transmission.
and the Museum fuì r Naturkunde Berlin the new study reveals that two bat-infecting parasites are closely related to parasites in rodents that are used commonly to model human malaria in laboratory studies.
The DNA from several genes of the bat parasites was sequenced at the Museum's Sackler Institute for Comparative Genomics resulting in the most comprehensive evolutionary tree of life for malaria parasites of bats to date.
and Plasmodium cyclopsi show patterns of evolutionary jumps from the rodent lineage into bats and then likely a reverse jump with a bat parasite reinfecting rodent hosts.
The authors suggest that the bat hosts which roost in trees may have been exposed to the same mosquito vectors that transfer the parasites between the tree-dwelling rodent hosts.
'Only by viewing forest sites along a gradient of logging disturbance ranging from pristine to heavily degraded were the team able to detect a gradual decline of some key bat species. The research confirmed the most vulnerable bats were those that tend to live in the cavities of old growth trees.
By linking bat captures with vegetation measurements from nearby plots the researchers were able to reveal how these animals declined as successive rounds of logging took their toll on forest structure and crucially the availability of tree cavities.

The study is an important step toward treating WNS according to Mylea Bayless Bat Conservation International's director of conservation programs in the U s. and Canada.
A marked decline in bat populations in the eastern United states was documented in a study published last month in PLOS One by Sybill Amelon a research biologist with the Forest Service in Columbus Mo
The study found cumulative declines in regional relative abundance by 2011 from peak levels were 71 percent for little brown bats 34 percent for tricolored bat 30 percent in the federally-listed
endangered Indiana bat and 31 percent for northern long-eared bats. In 2009 researchers identified the culprit behind WNS as a member of the genus Geomyces resulting in its name Geomyces destructans or G. destructans.

Ulanovsky chose to study the Egyptian fruit bat a very common bat species in Israel. Because these are relatively large the researchers were able to attach the wireless measuring system in a manner that did not restrict the bats'movements.
Ulanovsky in cooperation with a US commercial company created a wireless lightweight (12 g about 7%of the weight of the bat) device containing electrodes that measure the activity of individual neurons in the bat's brain.
which tracked wild fruit bats using miniature GPS devices. One of the discoveries was that when bats arrive at a fruit tree they fly around it utilizing the full volume of space surrounding the tree.
To simulate this behavior in the laboratory--an artificial cave equipped with an array of bat-monitoring devices--the team installed an artificial tree made of metal bars
when the bat is located in that area. Together the population of place cells provides full coverage of the cave--left and right up and down.
