MILLER, Christine W.*; EMLEN, Douglas J.; University of Montana; University of Montana: Maternal effects shift the allometry of a sexually selected trait in the heliconia bug Sexually selected traits are especially sensitive to environmental conditions. Mothers frequently influence the environment experienced by their offspring, and, thus, play an important role in the expression of sexually […]

FERRIS, M. T.*; BURCH, C. L.; University of North Carolina, Chapel Hill; University of North Carolina, Chapel Hill: Host range evolution of the bacteriophage &Phi 6: Are trade-offs required? Viral adaptation to novel hosts can alter fitness on other hosts, and this change depends on the host-specific effects that mutations exhibit. Here we show that […]

Rennes, France; Univ. Rennes, France; Univ. Rennes, France; Univ. Rennes, France; Univ. Rennes, France: Histology and histochemistry of the uterine glands and eggshell of the reproductively bimodal lizard, […]

WELCH, A.M.; College of Charleston: Heritability of lipid reserves in gray tree frog metamorphs Condition-dependence has emerged as an important assumption in models of sexual selection and life history evolution. Condition has been defined as a measure of physiological state that reflects the ability of an organism to acquire, store, and/or use resources to enhance […]

BOWDEN, R.M.*; JANZEN, F.J.; Illinois State Univ.; Iowa State Univ.: Growth and Reproduction During a Transitional Life History Stage Ontogenetic changes in reproductive characters can impact organismal life history. A variety of factors including reproductive frequency, clutch size, and egg size have been shown to increase with female age or body size in turtles. Previous […]

COX, Robert*; BARRETT, Michele; ZILBERMAN, Viktoriya; JOHN-ALDER, Henry; The Ohio State University; Rutgers University; Rutgers University; Rutgers University: Effects of sex and castration on growth of Yarrow�s Spiny Lizards (Sceloporus jarrovii) are reduced or absent in laboratory common-garden experiments Adult males average about 10% larger (longer in snout-vent length) than adult females in natural populations […]

KINGSOLVER, J.G.*; MASSIE, K.R.; RAGLAND, G.J.; SMITH, M.H.; Univ. of North Carolina, Chapel Hill: Breaking the temperature-size rule: Rapid population divergence in thermal reaction norms The temperature�size rule is a common pattern of phenotypic plasticity in which higher temperature during development results in a smaller adult body size (i.e., a thermal reaction norm with negative […]

BOBACK, S.M.*; GUYER, C.; Auburn University; Auburn University: A test of reproductive power in snakes Reproductive power is a contentious concept among ecologists and the model has been heavily criticized on theoretical and empirical grounds. Despite these criticisms, this model has successfully predicted the modal (optimal) size in three large taxonomic groups and shape of […]

LANDRY, S..O.; State University of New York, Binghamton: Venous Drainage in Short- and Long-faced Mammals In mammals, the venous drainage of the head proceeds through two major channels. The veins of the rostrum unite to form the facial vein, which picking up the linguo-facial and the superficial temporal vein, becomes the external jugular vein. (Humans […]

MCHENRY, MJ*; VAN NETTEN, SM; Univ. of California, Irvine; Univ. of Groningen: The mechanical design of the superficial neuromast in zebrafish The superficial neuromast (SN) is a microscopic structure within the lateral line system of fish that is used to detect water flow. The morphology and material properties of these delicate structures are not well […]
