Fire ants: Amazing subterranean architects
Daria Monaenkova, Postdoctoral Fellow
School of Physics

I will discuss the principles underlying the construction of underground nests by red imported fire ants. Large underground nests are crucial for fire ant survival, providing protection from severe weather and predators. Although fire ant nests are found in all soil types in both North America and South America, the areas with excessive soil moisture as well as the dry areas seems to be less favorable for a colony foundation.
The Complex Rheology and Biomechanics Lab, also known as the Crab Lab, has used x-ray computed tomography to study the effect of soil moisture content on the growth and architecture of fire ants nests. Because strong cohesion in wet soils leads to the competition between tunnel stability and the labor-intensity of the excavation, we have found an optimal soil wetness, which allows the most effective nest construction. This presentation will address the influence of moisture content and particle size on nest geometry, excavation techniques employed by fire ants, and show in-progress work on social aspects of nest construction.
Daria received her M.S. in Physics from Moscow State Aviation Technological University (Russia). In 2008 she joined the Micro- and Nanofluidic Research Laboratory at Clemson University as a research assistant and in 2012 she has successfully defended her PhD thesis in Material Science and Engineering there. That same year Daria accepted a Postdoctoral Fellow position at the School of Physics of Georgia Institute of Technology in the Complex Rheology and Biomechanics Lab.
Parking and Such
Java Vino is located diagonally across the street from Manuel's Tavern. There is parking behind the building and on Williams Mill Road across the street. Manuel's reserves the use of their lots at all times, but parking there hasn't presented a problem for our guests so far.
Enter the cafe on the street level and let them know that your order will count toward our minimum order requirement.
