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 73.11  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 […]

Meeting Abstract 73.3  Sunday, Jan. 6  Endurance Capacity of Mice Selectively Bred for High Voluntary Wheel Running MEEK, T.H.*; HANNON, R.M.; LONQUICH, B.; MARSIK, R.L.; WIJERATNE, R.S.; GARLAND, T.Jr.; Univ. of California, Riverside; Univ. of California, Riverside; Univ. of California, Riverside; Univ. of California, Riverside; Univ. of California, Riverside; Univ. of California, Riverside tmeek001@ucr.edu Mice from 4 […]

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 […]

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 […]

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 […]

Meeting Abstract 73.9  Sunday, Jan. 6  Cutaneous water loss and sphingolipids in the stratum corneum of house sparrows from desert and mesic environments MU�OZ-GARCIA, Agust�*; RO, Jennifer; BROWN, Johnie C; WILLIAMS, Joseph B; OSU; OSU; Applied Biosystems; OSU munoz-garcia.1@osu.edu Because cutaneous water loss (CWL) represents over a half of the total water loss in birds, selection pressures […]
