Meeting Abstract 125.1  Tuesday, Jan. 7 14:00  Shift in a life history trade-off linked with change in hormonal cross-talk ABOLINS-ABOLS, M*; KETTERSON, E D; Indiana University, Bloomington; Indiana University, Bloomington mabolins@indiana.edu Perhaps the most fundamental life history trade-off is that between reproduction and self-maintenance. This trade-off is mediated by the interaction of two major endocrine systems, the […]

NEMETH, Z*; SMEETS, M; RAMENOFSKY, M; Univ. of California, Davis; Rheinische Friedrich-Wilhelms-University; Univ. of California, Davis znemeth@ucdavis.edu Organisms are increasingly exposed to rapid changes in the environment, yet it remains difficult to predict their responses to such […]

Meeting Abstract 125-5  Thursday, Jan. 7 14:30  Thermal biology of insect immunity SINCLAIR, BJ*; SALEHIPOUR-SHIRAZI, G; FERGUSON, LV; Western University, Canada bsincla7@uwo.ca http://publish.uwo.ca/~bsincla7/ Research on overwintering insects often focuses on their tolerance to abiotic stress. However, animals are also part of complex ecological webs, including a range of pathogens that can threaten survival. Previous work hinted at […]
