[email protected]. EVOLUTIONARY INNOVATIONS IN ANTS TO THERMALLY STRESSFUL ENVIRONMENTS A Dissertation Presented by Andrew D. Nguyen to The Faculty of the Graduate College of The University of Vermont In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy Specializing in Biology May, 2017 Defense Date: March 29, 2017 Dissertation Examination Committee: Sara Helms Cahan, Ph.D., Co-advisor Nicholas J. Gotelli, Ph.D., Co-advisor Jill Preston, Ph.D., Chairperson Brent Lockwood, Ph.D. Cynthia J. Forehand, Ph.D., Dean of the Graduate College ABSTRACT Temperature is a fundamental environmental force shaping species abundance and distributions through its effects on biochemical reaction rates, metabolism, activity, and reproduction. In light of future climate shifts, mainly driven by temperature increases, how will organisms persist in warmer environments? One molecular mechanism that may play an important role in coping with heat stress is the heat shock response (HSR), which protects against molecular damage.
