Phi Kappa Phi award winners at EUReCA
Assistant Professor Brandon Matheny sponsored two undergraduates, Pawel Kosentka (biochemistry concentration) and Sarah Sprague (psychology major), in an undergraduate research project that examined the evolution of fungal toxins in the mushroom family Inocybaceae. This work was also performed in collaboration with Dr. Shawn Campagna and Amanda May in the Chemistry Department. Pawel and Sarah’s research was featured at the Exhibition of Undergraduate Research and Creative Achievement, also known as EUReCA. Of the 187 presentations, Pawel and Sarah’s poster won one of three Phi Kappa Phi awards. See https://news.utk.edu/2011/03/22/eureca-research-week/ for more information.
Science article on economic importance of bats
Bats in North America are under a two-pronged attack but they are not the only victim – so is the U.S. economy. Gary McCracken, head of the Department of Ecology and Evolutionary Biology at the University of Tennessee, Knoxville, along with lead author Justin Boyles of the University of Pretoria in South Africa, and coauthors Paul Cryan of the U.S. Geological Survey and Thomas Kunz of Boston University, analyzed the economic impact of the loss of bats in North America in agriculture and found it to be in the $3.7 to $53 billion a year range. This was published in the April 1 edition of Science.
Since 2006, more than a million bats have died due to a fungal disease called White-Nose Syndrome (WNS). At the same time, several migratory tree-dwelling species are being killed in unprecedented numbers by wind turbines. This hurts the economy because bats’ diet of pest insects reduces the damage the insects cause to crops and decreases the need for pesticides.
In fact, the researchers estimate the value of bats to the agricultural industry is roughly $22.9 billion a year, with the extremes ranging as low as $3.7 and $53 billion a year.
“These estimates include the reduced costs of pesticide applications that are not needed to suppress the insects consumed by bats. However, they do not include the downstream impacts of pesticides on humans, domestic and wild animals and our environment,” said McCracken. “Without bats, crop yields are affected. Pesticide applications go up. Even if our estimates were quartered, they clearly show how bats have enormous potential to influence the economics of agriculture and forestry.”
According to the researchers, a single colony of 150 big brown bats in Indiana eat nearly 1.3 million insects a year — insects that could potentially be damaging to crops.
WNS infects the skin of bats while they hibernate. Some species such as the little brown bat are likely to go extinct in parts of North America. The disease has quickly spread from Canada to Tennessee, Missouri and Oklahoma and actions to slow or stop it have proven unsuccessful.
It is unknown how many bats have died due to wind turbines, but the scientists estimate by 2020, wind turbines will have killed 33,000 to 111,000 annually in the Mid-Atlantic Highlands alone. Why migratory tree-dwelling species are drawn to the turbines remains a mystery.
Due to the economic and ecological importance, the researchers urge policy-makers to avoid a wait-and-see approach to the issue of widespread declines of bat populations.
“Not acting is not an option because the life histories of these flying, nocturnal mammals — characterized by long generation times and low reproductive rates — mean that population recovery is unlikely for decades or even centuries, if at all,” said McCracken.
According to McCracken, solutions will only be fueled in the next few years by increased awareness of the benefits of insectivorous bats among the public, policymakers and scientists.

Phylogenetics Summer of Code
PHYLOINFORMATICS SUMMER OF CODE 2011
http://informatics.nescent.org/wiki/Phyloinformatics_Summer_of_Code_2011
The Phyloinformatics Summer of Code program provides a unique opportunity for undergraduate, masters, and PhD students to obtain hands-on experience writing and extending open-source software for evolutionary informatics under the mentorship of experienced developers from around the world. The program is the participation of the US National Evolutionary Synthesis Center (NESCent) as a mentoring organization in the Google Summer of Code(tm) (http://code.google.com/soc/). EEB faculty member Brian O’Meara is one of the mentors of this program.
Students in the program will receive a stipend from Google (and possibly more importantly, a T-shirt solely available to successful participants), and may work from their home, or home institution, for the duration of the 3 month program. Each student will have at least one dedicated mentor to show them the ropes and help them complete their project.
NESCent is particularly targeting students interested in both evolutionary biology and software development. Initial project ideas are listed on the website. These range from visualizing viral epidemics to 3D protein structure evolution, rich annotation for TreeBASE content, exposing phenotype observations to the Encyclopedia of Life, to enhancing R packages for phylogenetic analysis. All project ideas are flexible and many can be adjusted in scope to match the skills of the student. We also welcome novel project ideas that dovetail with student interests.
TO APPLY: Apply online at the Google Summer of Code website (http://socghop.appspot.com/), where you will also find GSoC program rules and eligibility requirements. Each organization has a slightly different application format, and ours is at http://bit.ly/PhyloSoC2011-apptemplate. The 12-day application period for students opens on Monday, March 28th, and runs through Friday, April 8th, 2011.
INQUIRIES: phylosoc {at} nescent {dot} org. We strongly encourage all interested students to get in touch with us with their ideas as early on as possible. Working closely with potential mentors to develop your project proposal greatly increases your chance for acceptance. Do not underestimate the amount of time it takes to develop a competitive proposal.
