Grants on effects of invasion on bats



EEB PhD student Jessica Welch, a grad student with Gary McCracken and Dan Simberloff, recently received grants to study how invasive species affect a bat. From her abstract:

Aguiguan, a small island in the Northern Mariana Islands, is home to the only known population of the Emballonura semicaudata rotensis, a subspecies of Pacific sheath-tailed bat. Immediate research is necessary to determine an appropriate approach to its conservation. Two ubiquitous invaders, feral goats and lantana shrub have dense populations on Aguiguan. It is unknown whether these invasive species affect the Pacific sheath-tailed bat.

The grants were funded by Sigma Xi and Bat Conservation International. Jess was also inducted into Sigma Xi as an associate member.

Bats go where the food is




A recent paper in PLOS ONE by dept. head Gary McCracken and colleagues, including former UTK EEB grad students Veronica Brown and Paula Federico, as well as UTK postdoc Melanie Eldridge, analyzed insect DNA in bat feces. Their work suggests that bats change foraging locations to match prey abundance. It also supports previous researchers' findings that bats contribute substantially to agriculture, providing services that can amount to 12% of the value of a crop.

Abstract: 
The role of bats or any generalist predator in suppressing prey populations depends on the predator's ability to track and exploit available prey. Using a qPCR fecal DNA assay, we document significant association between numbers of Brazilian free-tailed bats (Tadarida brasiliensis) consuming corn earworm (CEW) moths (Helicoverpa zea) and seasonal fluctuations in CEW populations. This result is consistent with earlier research linking the bats' diet to patterns of migration, abundance, and crop infestation by important insect pests. Here we confirm opportunistic feeding on one of the world's most destructive insects and support model estimates of the bats' ecosystem services. Regression analysis of CEW consumption versus the moth's abundance at four insect trapping sites further indicates that bats track local abundance of CEW within the regional landscape. Estimates of CEW gene copies in the feces of bats are not associated with seasonal or local patterns of CEW abundance, and results of captive feeding experiments indicate that our qPCR assay does not provide a direct measure of numbers or biomass of prey consumed. Our results support growing evidence for the role of generalist predators, and bats specifically, as agents for biological control and speak to the value of conserving indigenous generalist predators.

Study on teaching highlighted by Science

Recent work by grad student Denise Kendall and assistant professor Beth Schussler was selected as an Editors' Choice by Science


Article abstract: Graduate teaching assistants (GTAs) are used extensively as instructors in higher education, yet their status and authority as teachers may be unclear to undergraduates, to administrators, and even to the GTAs themselves. This study explored undergraduate perception of classroom instruction by GTAs and professors to identify factors unique to each type of instructor versus the type of classes they teach. Data collection was via an online survey composed of subscales from two validated instruments, as well as one open-ended question asking students to compare the same class taught by a professor versus a GTA. Quantitative and qualitative results indicated that some student instructional perceptions are specific to instructor type, and not class type. For example, regardless of type of class, professors are perceived as being confident, in control, organized, experienced, knowledgeable, distant, formal, strict, hard, boring, and respected. Conversely, GTAs are perceived as uncertain, hesitant, nervous, relaxed, laid-back, engaging, interactive, relatable, understanding, and able to personalize teaching. Overall, undergraduates seem to perceive professors as having more knowledge and authority over the curriculum, but enjoy the instructional style of GTAs. The results of this study will be used to make recommendations for GTA professional development programs.

Hunting for aliens



UTK EEB PhD student Sara Kuebbing was recently featured in the Knoxville News Sentinel for her work as part of the Tennessee Exotic Plant Pest Council. She uses an iPad app to identify and track species that are invading the US from elsewhere, typically after introduction by humans. Such species can dramatically affect functioning of ecosystems: examples in the United States include kudzu, zebra mussels, and pythons.

EEB grad students and NIMBioS staff meet with Se. Corker staff

(From left) Kelly Sturner (NIMBioS), Jessica Bryant (EEB), and Emily Austin (EEB) met with Hunter Bethea, a legislative assistant of Sen. Corker.




Ecology & Evolutionary Biology (EEB) Department graduate students Emily Austin and Jessica Bryant along with Kelly Sturner, NIMBioS Education & Outreach Coordinator, were invited to visit the office of U.S. Sen. Bob Corker (R-TN) to talk about NIMBioS’ and EEB’s involvement in the USA Science & Engineering Festival. The group spoke with Hunter Bethea, legislative assistant to Corker, about how participation in federally-supported science education and outreach programs, such as NSF research experiences for undergraduates and Department of Energy education programs, led them to pursue science careers, and now inspire them to give back through participating in science outreach.

EEB/NIMBioS at USA Science and Engineering Festival

Sarah Wood, undergraduate in the Classen lab, teaches elementary students how to measure plant traits.




The USA Science and Engineering Festival on April 28 and 29 in Washington, DC brought the excitement of science to people from around the country. EEB and NIMBioS teamed up and presented two booths in the festival. Emily Austin and Jessica Bryant, Classen lab graduate students, taught Science Fest attendees about fungal decomposition of wood using decaying logs in terrariums. Sarah Wood, an undergraduate in the Classen Lab, and Kelly Sturner, education and outreach coordinator in NIMBioS, taught visitors about intra- and inter-specific variation in Solidago plants by having them measure stem and leaf traits. Both booths encouraged observations, data collection and graphical analysis. Many Science Fest attendees were families with elementary or middle school-aged children, but several teachers were there to pick up science project ideas for their classrooms. In all, an estimated 300,000 people left the event having learned at least one thing: science is exciting!

PNAS paper on complex codon usage patterns



EEB grad student Premal Shah (now a postdoc in the Plotkin lab at the U. of Pennsylvania) and his adviser, Associate Prof. Mike Gilchrist, recently published a paper in the Proceedings of the National Academy of Sciences on "Explaining complex codon usage patterns with selection for translational efficiency, mutation bias, and genetic drift."

Abstract: The genetic code is redundant with most amino acids using multiple codons. In many organisms, codon usage is biased toward particular codons. Understanding the adaptive and nonadaptive forces driving the evolution of codon usage bias (CUB) has been an area of intense focus and debate in the fields of molecular and evolutionary biology. However, their relative importance in shaping genomic patterns of CUB remains unsolved. Using a nested model of protein translation and population genetics, we show that observed gene level variation of CUB in Saccharomyces cerevisiae can be explained almost entirely by selection for efficient ribosomal usage, genetic drift, and biased mutation. The correlation between observed codon counts within individual genes and our model predictions is 0.96. Although a variety of factors shape patterns of CUB at the level of individual sites within genes, our results suggest that selection for efficient ribosome usage is a central force in shaping codon usage at the genomic scale. In addition, our model allows direct estimation of codon-specific mutation rates and elongation times and can be readily applied to any organism with high-throughput expression datasets. More generally, we have developed a natural framework for integrating models of molecular processes to population genetics models to quantitatively estimate parameters underlying fundamental biological processes, such a protein translation.
