UT EEB undergraduate at STEM Education Research Conference
Sarah Wood, an EEB sophomore, was one of 9 undergrads from across the state of TN selected to present a poster and attend the MTSU 5th annual STEM Education Research Conference Funded by Tennessee Space Grant and MTSU. For more information see this article in the Tennessean.
UT EEB undergraduate teaches science on the National Mall
UTK EEB undergraduate Sarah Jeanne Wood recently participated in a 2-day Science Expo on the National Mall, where half a million people came to learn about science and engineering. Sarah presented on her research on intraspecific variation in Solidago, done in collaboration with postdoc Lara Souza and EEB assistant professor Aimée Classen. For a detailed story, please see this article from UTK’s Arts and Sciences magazine, Higher Ground.

REU supplement to Matheny grant
Brandon Matheny has gotten a Research Experiences for Undergraduates (REU) grant from the NSF for his existing grant for a revision of Australian species of Inocybaceae. Quoting from the NSF REU site, “The Research Experiences for Undergraduates (REU) program supports active research participation by undergraduate students in any of the areas of research funded by the National Science Foundation. REU projects involve students in meaningful ways in ongoing research programs or in research projects specifically designed for the REU program.”
Grad student Joshua Birkebak receives award for taxonomy

Grad student Mackenzie Taylor to become assistant prof. at Creighton U.
Mackenzie Taylor, a PhD student in Joe Williams’ lab, is off to an assistant professorship at Creighton University directly from grad school. Mackenzie studies evolution of the progamic phase in water lilies (the stage between pollination and fertilization).
Boyer Science paper
Alison Boyer, a new Research Assistant Professor in EEB, just published a paper in last week’s issue of Science.
The Evolution of Maximum Body Size of Terrestrial Mammals
Felisa A. Smith, Alison G. Boyer, James H. Brown, Daniel P. Costa, Tamar Dayan,
S. K. Morgan Ernest, Alistair R. Evans, Mikael Fortelius, John L. Gittleman,
Marcus J. Hamilton, Larisa E. Harding, Kari Lintulaakso, S. Kathleen Lyons,
Christy McCain, Jordan G. Okie, Juha J. Saarinen, Richard M. Sibly, Patrick R. Stephens, Jessica Theodor, Mark D. Uhen
Science 330, 1216 (2010);
DOI: 10.1126/science.1194830
Abstract:
The extinction of dinosaurs at the Cretaceous/Paleogene (K/Pg) boundary was the seminal event that opened the door for the subsequent diversification of terrestrial mammals. Our compilation of maximum body size at the ordinal level by sub-epoch shows a near-exponential increase after the K/Pg. On each continent, the maximum size of mammals leveled off after 40 million years ago and thereafter remained approximately constant. There was remarkable congruence in the rate, trajectory, and upper limit across continents, orders, and trophic guilds, despite differences in geological and climatic history, turnover of lineages, and ecological variation. Our analysis suggests that although the primary driver for the evolution of giant mammals was diversification to fill ecological niches, environmental temperature and land area may have ultimately constrained the maximum size achieved.
