Description:You’re invited to attend Lizzy Rylance’s Master’s Defense
  Seminar as she presents her research on one of nature’s most essential 
 pollinators:\n\n“Can Bees Handle the Heat? Effects of Genotype and Accli
 mation on Honeybee Thermal Responses”\n\nDate: Friday\, June 20\, 2025\n
 Time: 11:00 AM\nLocation: NR345\nVirtual Option: bit.ly/HotBuzz\n\nAdvised
  by Dr. Dhruba Naug\, Lizzy’s work explores how different honeybee genot
 ypes and acclimation strategies influence their ability to tolerate high t
 emperatures—an increasingly important question in the context of climate
  change.\n\nWhether you\\'re interested in insect physiology\, climate ada
 ptation\, or just want to support a fellow researcher\, we hope you’ll j
 oin us for this engaging presentation.\n\nVisit our website for more inf
 ormation on our seminars and follow us on social media for more announceme

 n\n“As global temperatures rise\, animals are increasingly exposed to st
 ressful conditions that challenge their physiological and behavioral perfo
 rmance. Genetic variation and phenotypic plasticity are two key factors th
 at influence how organisms respond to such environmental change. Here\, we
  investigated how thermal responses in honeybees (Apis mellifera) are infl
 uenced by (1) genotypic differences in a key metabolic enzyme and (2) shor
 t-term thermal acclimation. First\, we examined genetic variation at the m
 alate dehydrogenase (MDH-1) locus and its effects on metabolic rate\, loco
 motor activity\, and learning performance across a range of temperatures. 
 Next\, to assess plasticity\, bees were acclimated for 48 hours to either 
 cool or warm conditions and then tested at matching or mismatched temperat
 ures. Our results demonstrate that both genetic variation and thermal accl
 imation influence performance\, but their effects differ by trait. Genotyp
 e-specific performance differences across temperatures provide evidence th
 at MDH-1 variation may contribute to thermal adaptation\, and we discuss t
 hese results in the context of Slow-Fast behavioral phenotypes. In contras
 t\, short-term acclimation had limited capacity to buffer behavioral respo
 nses to changing temperatures. Together\, these findings emphasize the imp
 ortance of integrative approaches to evaluating thermal responses and have
  important implications for understanding pollinator performance and adapt
 ation in a warming world.”\n\n11:00 am
