Introduction
Is the bat population all of sudden dying? Is it the end of the lives of the only vital flying
mammal in the world?
Recently, over the last four years, thousands of bats have been facing death due to amysterious disease that has hunted and killed bats by the thousands not only in the upper
northeastern part of the U.S such as New York, Connecticut, and Massachusetts but
Pennsylvania alone. Scientists and researchers four years ago diagnosed the disease as White
Nose Syndrome (WNS), but further research to find a cure for this disease remains unknown. InPennsylvania, research has been gathered in the past two years by biologists and researchers by
visiting caves testing bats for WNS. Surprisingly, according to statistics WNS in Pennsylvania
has increased in the last two years as more shocking discoveries are seen as more bats are beingfound dead inside caves and outside on the landscape. It is certain that in the past four years
(2006-2010) WNS has almost wiped out large bat populations in the northeast and it has become
a concern that WNS is becoming unstoppable as it spreads out West as well.
Having lived and survived for up to 50 million years, bats have become a great source andhelpful hand in improving agricultural aspects, never the less, replenishing ecosystems. If it were
not for bats, insect populations will sky rocket increasing the spread of malignant diseases,
agriculture will have an enormous impact by lowering its productivity due to insect infestation,and habitats and niches in rainforests or deserts will decline without bat pollination of flowers
and fertilization of fecal matter to replenish ecosystems.
I will start off the article by first, explaining briefly basic information about bats such aswhere they live and what they eat. Moreover, I will explain the significance that bats have on the
planet being pollinators, pest control agents, and seed dispersers. I will then move on to making a
brief introduction of White Nose Syndrome, the fungus responsible for causing the disease, andfurther explain in detail its effect on bats. Furthermore, I will talk about the discoveries of WNS
starting from the year that it was first discovered in the United States (2006) to where it is
affecting bats in the present day. Then, I will talk about bat observations made by biologists and
researchers when visiting the caves in Pennsylvania, moreover observations and actions madeand taken by the Pennsylvania Game Commission to help prevent the spread of WNS. Finally, I
will talk about the actions that the public can take to prevent white nose syndrome and treatments
that researchers have been trying to come up with to cure WNS in bats.

Credentials
Moving onto my senior year and being an Animal Science major at Penn State University, I
believe that I can be a great candidate for this article. Not knowing much about white nose
syndrome in bats before researching to write this article I have learned a lot through web articles
and newspaper documents on the disease. Interning at Centre Wildlife Care, a wildliferehabilitation near Shaver’s Creek Pennsylvania, I have learned a lot from wildlife rehabber Robyn Graboski. Founder and director of Centre Wildlife, Robyn Graboski has rehabilitated
wildlife for almost twenty two years. Among the wildlife, Robyn knows about bats to give meenough information about WNS. Although most of my research was found from articles on the
web, I was able to grab some information on WNS from Robyn, explaining that WNS was
confirmed as a disease not an illness and it is affecting most of the bat in cave hibernacula inPennsylvania. In close contact with the Pennsylvania Game Commission (PGC), Robyn has been
able to give me some email updates from the PGC concerning WNS along with information on
WNS and how one help save them. With her help I have been able to gather enough information
on WNS in bats. Furthermore, I researched through newspaper articles and Proquest articles
through the Penn State Library website finding detailed information on bat behavior, deaths, andareas affected by WNS.
With my prior research and time management skills, along with your help and our English
instructor, and PSU libraries, this article has the potential to be informative, persuasive, and
intriguing. My strong interest for writing this article builds my hope to spark the reader with
interest as well as allowing the reader to find it entertaining to read. Furthermore, the topic andarticle I am writing for the PA Center for the Book Project will be completed and in a manner
that is acceptable to your standards.
Research
No books on White Nose Syndrome in bats have been published due to being a recent
discovery of the disease. However, my research includes newspaper articles, journals, aninterview, and the web articles on WNS. As I mentioned before, I have researched and gathered
enough information through the Penn State library website. These sources include NewsBank andProquest articles. From the Newsbank Access World News, I found information on updates of WNS in the past four months and observations made a year ago by researchers on WNS when
caves were visited in Pennsylvania. Furthermore, there is information based on recent treatments
that scientists are experimenting with to find a cure for WNS as actions taken by PGC to preventthe spread of WNS as well as ways that the public can help to reduce the spread of the disease.
There are other several articles that discuss, as reported by biologists and researchers, normal
hibernating behavior in bats compared to bats that have been affected by WNS. The Proquest
articles discuss statistics of increasing bat deaths in upper northeastern states such as New York,Connecticut, Massachusetts along with bat deaths in Pennsylvania.
Aside from researching in the PSU library website, I found a variety of images depicting what
WNS looks like on bats. Moreover, I picked out several photos showing the physical conditions
of bats to provide the public with an idea of how serious this disease has affected bats.Furthermore, speaking with wildlife rehabber Robyn Graboski about WNS allowed me to
understand and learn more about the disease. In close affiliation with the Pennsylvania Game

Commission, Centre Wildlife Care has received recent updates through emails sent on the spread
and number of bats deaths in Pennsylvania caused by WNS.
Technical Description
White Nose Syndrome (WNS) is a deadly fungal disease that affects bats in hibernacula, cave
or mines where bats hibernate. For the past four years, WNS has been spreading affecting bats
from New England to as far west as Missouri. As of now, the fungal disease remains untreatableand as concerns keep rising, the disease will continue to spread.
Four years ago (2006) in Albany, New York, it the first discovery ever made when hundreds of bats were found dead by biologists exploring nearby caves in the winter. The same physiological
characteristics were seen on the bats dead or alive: the
white fungus appearing on their muzzle and wing
membranes (sometimes appearing on ears). As more
and more investigations were made by biologistsvisiting caves, more dead bats were found on the
landscape near or inside the caves. The white fungaldisease took off into spreading from northeast to New
England and south to into eastern Pennsylvania and
New Jersey, which soon gave the outbreak the nameWhite- nose Syndrome. (close-up of map onhttp://scienceblogs.com/zooillogix/2010/04/white_nose
_syndrome.php )
The white fungus, belonging in the genus Geomyces
distructans, usually appears on the muzzle (around the
nose area) on bats. Up close, the small patches appearlike fuzzy white mold, such as that found on rotten
fruit. In other cases, the fungus is seen on the backs of
bats and appears like white snowflakes bound to theback. However, as seen by researchers and biologists,
the fungus appears on the ears, nose, and wing
membranes the majority of the time.Geomyces distructans the name given to the fungus,
had not been known to man and science before,
remaining undiscovered until the outbreak of WNS in
caves and mines in 2006. It is given the possibility thatEuropean travelers had introduced the fungus in North
America when visiting nearby caves by carrying the
fungal spores on their clothing. Yet, little is known if the fungus came from a different country
or remained undiscovered by residing in the cool temperatures in caves in North America. Ateam of scientists lead by David Blehert and Andrea Gargas, experimented and studied the
fungus carefully monitoring its growth and different temperatures (published in 2008).
8/9/2019 WNS Proposal
http://slidepdf.com/reader/full/wns-proposal 4/11
Surprisingly the slow growing fungus grew better at 37°F
and 45°F rather than at 75°F (showed no growth). These
cold temperatures were similar to that found in infected batcaves.
In the winter seasons, bats usually hibernate in the deep
darkness of caves or mines and awaken once or twice every15-30 days to urinate, drink, and mate. Interestingly, bats
lower their temperatures to a range of 35-50° F barely above
the ambient cave temperature while simultaneously
lowering their immune response. Since Geomyces grows in
cold temperatures, there is the explanation why it is growingon bats. With white nose syndrome affecting bats,
hibernating behavior in bats has changed dramatically.
According to witnesses in Chester Mines, Massachusetts in
2009, bats were spotted active in the months of January-through mid March flying during the daylooking for food and water. In Mifflin county mines in Pennsylvania, bats were interestingly and
strangely discovered dead on the snow in a ring around trees. For many biologists andresearchers, there is strong evidence that WNS has affected hibernating behavior in bats.
Working at a lab at Bucknell University in Pennsylvania, biology professor Dr. DeeAnn
Reeder, studies and performs field work on immune responses in hibernating bats. Over the past
three years, Reeder has been questionably studying and testing periodic arousals of bats duringhibernation. Strangely enough, bat arousal time affected with WNS rouse bats every three or four
days depleting their fat reserves, which explains why bats appear dehydrated and most of the
time emaciated. When a bat is dehydrated the wing membranes appear shriveled up similar towhen a leaf has not been exposed to water in a long
time. According to Reeder, “Sometimes we find dead bats in a ring around trees. We’re not sure exactly, but
I think their body fat gets so lean they wake up andthink it’s spring and it’s time to feed, but don’t find
any insects in winter, roost in a tree, die and fall.”While visiting the caves in Mifflin County with
students last year, Reeder has felt overwhelmed to seethese creatures die in increasing numbers. Reeder
hypothesized that bats have an immune-surveillance
system which means that during hibernation, batsincrease their body temperature to fight off any
diseases and then lower their temperature again. These
periodical warm-ups is what boosts the bat’s
physiological system. WNS however, arouses bats,thus leading bats to awaken frequently causing them to
expend their stored energy in search for food.
Working alongside with Dr. Reeder, Greg Turner, a
biologist with the Game Commission’s WildlifeDiversity Section, had also investigated and researched
the Mifflin County mines in 2008 counting the number of bats that so far had survived in the
cave. “There’d be about 2,000 to 3,000 bats in the area. So far, we’ve counted about 500 and a
8/9/2019 WNS Proposal
http://slidepdf.com/reader/full/wns-proposal 5/11
lot of them are dead. This past fall we began to examine the health of our bats to see if they came
into hibernation…using telemetry gear and data-loggers to monitor the body temperatures and
arousal patterns…” According to Reeder, the two biologists along with the Pennsylvania Game
Commission estimated about 80-90% mortality in some of the caves in the area in 2008.
The Pennsylvania Game Commission (PGC) has take action to prevent the spread of WNS.
Caverns including the Aitkin Cave, a wellknown hibernation site in a 43-acre preserve
in Mifflin County, PA have been banned
entry and are closed to the public. Althoughthe disease is not contagious and harmful to
humans, pets and even livestock, the fungal
spores are capable of clinging onto clothingor fur. To make bat hibernacula save, it is
better to keep caves closed to prevent further
spread and contamination. Caving in the
northeast and areas where WNS has settled,
has been banned by the National Park Service, the U.S. Department of Agriculture
Forest Service and The Nature Conservancyto prevent further spread of WNS.
The Game Commission in general performs field work in caves instate every year. In the past
two years (2008-2010) however, the Commission has dived further surveying 20 to 30
hibernacula between January and March monitoring for WNS. Moreover, the agency assistedresearchers in investigating bats by looking for normal metabolic rate of hibernating bats,
studying normal immune response capabilities of bats, and measuring if there is sufficient fat
stores in bats before hitting hibernation. It is important, not only for the Game Commission, butbiologists and bat researchers to note these hibernating characteristics in bats since hibernation
has become critical ever since the spread of WNS.
Conclusion
After providing an introduction on WNS in bats, discussing my credentials, informing you on
my current research, and writing a technical description, I hope you are convinced of my ability
to write about this topic to the highest level. I intend to write in a way that the reader willunderstand my topic fully. Any questions or concerns feel free to write any comments or advice I
would greatly appreciate it. I therefore requests your permission to continue my research and
writing on WNS for the article. Thank you for your time Allen.
