Vanderbilt researcher finds evidence for ant caste systems driven by chemo-sensing responses
Mar. 13, 2023—By Andy Flick, Evolutionary Studies scientific coordinator Stephen Ferguson, first-author of a new paper with his postdoctoral advisor, Laurence Zwiebel, Cornelius Vanderbilt Chair in Biological Sciences, and two undergraduates associated with the lab, Isaac Bakis (alumnus) and Nicholas Edwards, confirmed the existence of a specialized soldier caste within an ant species in a paper titled,...
Vanderbilt researchers bring paleoecology into the 21st century
Jul. 7, 2022—By Andy Flick, Evolutionary Studies scientific coordinator Science is an inherently collaborative endeavor. When a respected colleague courteously disagrees with your point of view, it can lead to great new papers, perspectives and collaborations. In that same vein, feedback from editors and reviewers of academic journals is an often-understated driver of new research directions. Assistant...
“The Hunger Games: E. coli edition” demonstrates how mutualism and cooperative behavior shape species
May. 20, 2022—Andy Flick, Evolutionary Studies Initiative scientific coordinator Bacteria, not unlike humans, can take up more resources than necessary. When this happens, synthesized byproducts can leak into the environment. This allows the nearby bacteria to evolve cooperative behaviors, such as using the byproducts as nutrients. Cooperation in bacterial communities has also been previously observed with behaviors...
