Meeting Abstract 63.6  Jan. 7  Resource allocation to testes in the walnut fly, Rhagoletis juglandis CARSTEN-CONNER, L.D.*; O’BRIEN, D.M.; University of Arizona; University of Alaska, Fairbanks carsten@email.arizona.edu Testes size often predicts whether a male will win during episodes of sperm competition. However, little is known about the source of nutrients allocated to testes development. Among holometabolous insects, […]

Meeting Abstract 63.3  Jan. 7  Exposing the embryo to maternal stress: an adaptive predictive mechanism or an unavoidable developmental cost? LOVE, Oliver/P*; WILLIAMS, Tony/D; Simon Fraser University, Canada; Simon Fraser University, Canada olovea@sfu.ca How and why maternal stress affects offspring phenotype has become a subject of considerable interest in studies spanning numerous vertebrate taxa. In birds, embryonic […]

Meeting Abstract 63.1  Jan. 7  Anemia associated with egg production is estrogen-dependent: a basis for the cost of reproduction? WAGNER, E.C.*; PREVOLSEK, J.S.; WYNNE-EDWARDS, K.E.; WILLIAMS, T.D.; Simon Fraser University; Simon Fraser University; Queen’s University; Simon Fraser University ewagner@sfu.ca The �cost of reproduction� (i.e. trade-offs between current reproduction and future fecundity and/or survival) is a central concept […]

Meeting Abstract 62.4  Jan. 7  Variation in gene expression among the brains of behaviorally distinct zebrafish strains: no evidence for parallel transcriptome evolution during domestication. ROBISON, B.D.*; DREW, R.E.; SETTLES, M.; CHURCHILL, E.; MORETZ, J.; MARTINS, E.P.; University of Idaho; University of Idaho; University of Idaho; University of Idaho; Indiana University; Indiana University brobison@uidaho.edu Fearfulness and anxiety […]

Meeting Abstract 62.1  Jan. 7  Evolution of avian personalities: adaptive variation or hormonal constraint? DUCKWORTH, R.A.*; SOCKMAN, K.W.; University of Edinburgh; University of North Carolina rad3@duke.edu The correlated expression of behavior across different contexts can reflect constraints to the independent evolution of behavior or a suite of behaviors favored by selection. Behavioral constraints are thought to result […]

Meeting Abstract 62.3  Jan. 7  Error in Non-Human Animals: the Effects of Motivation and Distraction on Animal Performance HOFFMAN, AM*; TUTTLE, EM; Indiana State University; Indiana State University hoffman@mama.indstate.edu In the everyday life of a human, mistakes are so common that they are reflected in numerous clich�s and proverbs, and a large body of research exists on […]

Meeting Abstract 62.2  Jan. 7  Behavioral syndromes and adaptation to captivity in the zebrafish, Danio rerio OSWALD, M.E.*; ROBISON, B.D.; University of Idaho; University of Idaho oswa2750@uidaho.edu Behavioral syndromes are defined as individual consistency in a suite of behaviors across multiple situations (e.g. being very bold regardless of whether predators are present or absent). The concept of […]
