BERKE, S. K.; MILLER, M.; WOODIN, S. A.; University of South Carolina; University of South Carolina; University of South Carolina: Modeling Behavior through Reproductive Value Historically, behavioral modeling has been largely limited to simulations and dynamic programming models, perhaps because it is easier to write �rules� for individual behavior than to write continuous equations describing […]

ELSTROTT, J.*; IRSCHICK, D. J.; Tulane University; Tulane University: Evolutionary correlations among morphology, habitat use, and clinging performance in Caribbean Anolis lizards A central issue in evolutionary biology concerns whether morphology, performance, and habitat use have co-evolved. We investigated evolutionary relationships among the size of the subdigital toepad, clinging ability, and perch height in 12 […]

GOMEZ-MESTRE, I.*; WARKENTIN, K.M.; Boston University; Boston University: Embryo response to risk varies among species of leaf-breeding treefrogs, genus Agalychnis Arboreal embryos of red-eyed treefrogs, Agalychnis callidryas, hatch prematurely in response to various egg-stage risks, including attack by egg-eating snakes and wasps, infection by pathogenic fungus, and submergence underwater (risk of drowning). Early hatching is […]

MINER, Benjamin G; Univ. of California, Davis: Effects of environmental variation on the evolution of phenotypic plasticity The ability of an organism to change its phenotype in response to environmental (i.e. phenotypic plasticity) is ubiquitous in nature. In many cases phenotypic plasticity is adaptive and allows individuals of a population to cope with environmental variation. […]

WELCH, A. M.; University of North Carolina-Chapel Hill: Ecological genetics of larval and metamorphic traits: how do populations respond to fluctuating selection? A population�s response to selection depends on the quantitative genetic basis of traits under selection. When populations experience variable environmental conditions, response to selection also depends on the degree to which a given […]

BEAUMAN, R. L.; KAHN, P. F.; MENDON�A, M. T.; Auburn University: Short-term effects of burrow collapse on corticosterone levels and immune response of gopher tortoises The gopher tortoise is a federally listed species in the western portion of its range, and a species of concern elsewhere. Their burrows are often collapsed and tortoises become entombed […]

MCNABB, F.M.A.; QUERAL-KIRKPATRICK, L.T.; Virginia Tech; Virginia Tech: Endocrine Disruption and Thyroid Adaptation in Quail We studied the effects of sustained ammonium perchlorate (AP) exposure (.013-4,000 mgAP/l [ppm] in drinking water) for up to 8 weeks on chicks and adult bobwhite quail. AP competitively inhibits iodide uptake into the thyroid gland. We measured plasma thyroid […]
