Meeting Abstract 73.4 Sunday, Jan. 6 Testing for temperature trade-offs in lizards ADOLPH, S.C*; BADGER, M.; Harvey Mudd College; Harvey Mudd College adolph@hmc.edu Trade-offs in physiological performance between high and low temperatures are widely assumed to exist. However, temperature trade-offs in whole-organism traits have been surprisingly difficult to detect among individuals within populations. We tested for temperature […]

Molecular mechanisms of receptor-mediated yolk uptake underlying phenotypic variation in egg size
Meeting Abstract 73.6 Sunday, Jan. 6 Molecular mechanisms of receptor-mediated yolk uptake underlying phenotypic variation in egg size HAN, D*; WILLIAMS, T.D.; Simon Fraser University dongh@sfu.ca Natural selection acts on variation within species, and thus studying intraspecific or inter-individual variation is necessary to understand the evolution of phenotypic variation in life-history traits. However, our knowledge of the […]

Meeting Abstract 73.10 Sunday, Jan. 6 Geographic variation in the response of timekeeping systems to environmental cues in three populations of garter snakes (Thamnophis sirtalis): Common garden experiments LUTTERSCHMIDT, D.I.*; MASON, R.T.; Oregon State Univ., Corvallis; Georgia State Univ., Atlanta; Oregon State Univ., Corvallis Lutterschmidt@gsu.edu The ability to track changing environmental cues so that intrinsic processes are […]
Experimental manipulation of workload in European starlings effects on oxidative stress
Meeting Abstract 73.11 Sunday, Jan. 6 Experimental manipulation of workload in European starlings: effects on oxidative stress BOURGEON, S.*; WILLIAMS, T.D.; Simon Fraser University; Simon Fraser University sbourgeo@sfu.ca Oxidative stress is widely held to be one of the main proximate mechanism underlying ageing and costs of reproduction. We examined the effects of experimental manipulation of breeding effort […]

Effects of Long-term Calorie Restriction of the Host on Establishment, Survival and Resistance to Oxidative Stress of the Intestinal Nematode Heligmosomoides bakeri
Meeting Abstract 73.8 Sunday, Jan. 6 Effects of Long-term Calorie Restriction of the Host on Establishment, Survival and Resistance to Oxidative Stress of the Intestinal Nematode Heligmosomoides bakeri KRISTAN, Deborah M.*; ACOSTA, Wendy; California State University San Marcos dkristan@csusm.edu Long-term calorie restriction (CR) has many physiological benefits, including enhanced immune function. Despite immune benefits, long-term CR increases […]
Does community composition affect performance in Rivulus hartii
Meeting Abstract 73.2 Sunday, Jan. 6 Does community composition affect performance in Rivulus hartii? OUFIERO, Christopher E.*; WALSH, Matthew R.; DO, Tuan; U C, Riverside coufi001@student.ucr.edu The purpose of this study was to determine the effect of community composition on performance in Hart�s killifish (Rivulus hartii). R. hartii is an egg laying fish that occurs throughout the […]
Do long term changes in environmental temprature affect thermal tolerance in lizards
Meeting Abstract 73.5 Sunday, Jan. 6 Do long term changes in environmental temprature affect thermal tolerance in lizards? MCMILLAN, D.M*; IRSCHICK, D.J.; Univ. of Massachusetts, Amherst; Univ. of Massachusetts, Amherst mcmillan@bio.umass.edu In recent years, ecologists have emphasized studies on the effects of global climate change on naturally occurring animal populations. However, climatic changes are often subtle, and […]
