MCLISTER, JD; DEARING, MD; University of Utah; University of Utah: Differences in juniper consumption among woodrat species is related to different rates of phase I biotransformation Herbivores may evolve the ability to consume a toxic plant either by developing specialized biotransformation pathways to deal with the secondary compounds specific to that plant (i.e., qualitative) or […]

HALEY, S*; DEARING, M.D.; University of Utah: Detoxification of plant secondary compounds by woodrat herbivores, genus Neotoma. Mammalian herbivores routinely consume diets laden with toxins, yet the way in which wild herbivores detoxify plant secondary compounds is largely unknown. We took a pharmacological approach to understanding how a specialist (Neotoma stephensi) and generalist (Neotoma albigula) […]

MCMILLAN, D.M.*; FEARNLEY, S.L; STRODE, E.P; RANK, N.E; DAHLHOFF, E.P; Santa Clara University; Sonoma State University; Santa Clara University; Sonoma State University; Santa Clara Universtiy: Survival, growth and metabolic rate depends on environmental temperature, Hsp70 expression and PGI genotype in larvae of a montane leaf beetle The willow beetle Chrysomela aeneicollis is found in thermally […]

HENRY, J.R.*; HARRISON, J.F.; Arizona State University, Tempe; Arizona State University, Tempe: Plastic and evolved responses of tracheal dimensions to varying atmospheric oxygen content in Drosophila melanogaster. Structural changes in the tracheal system during development have the potential to allow insects to compensate for varying atmospheric oxygen levels. We investigated how oxygen availability affects the […]

GIBBS, Allen G.; VANIER, Cheryl H.; Univ. of Arizona; Univ. of Arizona: Gene expression in desiccated and starved Drosophila We studied the effects of desiccation stress on gene expression patterns in Drosophila melanogaster. Because desiccation involves the removal of both food and water, we used two control treatments: flies with water but no food (starved […]

ALBERS, Melissa A; BRADLEY, Timothy J; University of California, Irvine; University of California, Irvine: Fecundity in Drosophila melanogaster populations selected for enhanced desiccation resistance We investigated the effect of dehydration and subsequent rehydration on fecundity in five populations of Drosophila melanogaster selected for enhanced desiccation resistance (D populations) and their five paired control populations (C […]

LOVE, O.P.*; WILLIAMS, T.D.; Simon Fraser University, British Columbia, Canada; Simon Fraser University, British Columbia, Canada: Corticosterone provides a link between maternal condition and sex-specific adjustment of offspring quality Sex allocation theory predicts that females in better condition are expected to invest in the more expensive sex (most often sons), while those in poor condition […]

ROSENBLUM, Erica Bree*; HOEKSTRA, Hopi E.; NACHMAN, Michael W.; University of California, Berkeley; University of California, San Diego; University of Arizona: Reptile Color Variation and Mc1r Recent advances in understanding the genetics of pigmentation make color variation a tractable system to study the molecular basis for ecologically relevant traits across vertebrates. Here, we evaluate the […]

MYERS, E.M.; JANZEN, F.J.; ADAMS, D.C.; Iowa State University; Iowa State University; Iowa State University: Quantitive Genetics of Shape Variation in the Slider Turtle (Trachemys scripta) Shape variation is widespread in nature and embodies both a response to and a source for evolution and natural selection. To detect microgeographic patterns of shape evolution, one must […]

PLACE, Aaron J.; Oklahoma State University: Is the current function of the rattlesnake rattle changing from an auditory to a composite auditory/visual signal? Rattlesnakes are an ideal model system in which to study the evolution of defensive behavior. I tested the hypothesis that large body size, the presence of conspicuous tail banding, and aggressive temperament […]
