WARD, C.K.*; MENDONCA, M.T.; Auburn University; Auburn University: The Effect of Coal Fly Ash on Corticosterone, Testosterone and Metabolism in the Southern Toads, Bufo terrestris At the Savannah River Site, South Carolina, Southern toads ( Bufo terrestris) bred in coal fly ash basins, which contain elevated levels of heavy metals in sediments. Toads in ash […]

HOPKINS, W.A.*; WINNE, C.T.; Savannah River Ecology Laboratory; Savannah River Ecology Laboratory: Swimming performance of neonate black swamp snakes (Seminatrix pygaea) exposed to an acetylcholinesterase-inhibiting pesticide Environmental contaminants have direct effects on organisms at the molecular, cellular, and tissue levels, but the net result of these sub-organismal effects are only consequential to exposed populations if […]

FORD, D.K.; Ohio University: Sublethal physiological effects of multiple stressors on energy allocation patterns of Malaclemys terrapin Stress is an environmental condition or external constraint that restricts the rate of resource acquisition and energy allocation that may ultimately reduce survivorship or fecundity. An organism incurs an energetic cost, such as an increase in metabolic rate, […]

KITANA, N.*; WON, S.J.; CALLARD, I.P.; Boston University; Boston University; Boston University: Environmental and hormonal impacts on reproduction and development in the freshwater turtles Previous observations on the freshwater turtle (Chrysemys picta) obtained from a Superfund site on Cape Cod, MA suggested endocrine disruption of reproductive processes. To determine the possible loci in the hypothalamic-pituitary-gonadal-hepatic […]

BARBEAU, T.R.*; University of Florida: Decreased Gonadal Steroidogenesis and Increased Plasma Insulin-Like Growth Factor-1 in Frogs Exposed to Aquatic Nitrates Contamination of aquatic ecosystems with anthropogenic sources of nitrates has become of increasing concern to researchers in the past few years. Aquatic nitrates in North America range from less than 1 to greater than 100 […]

LIGON, D. B.; HUSAK, J. F.; PETERSON, C. C.; Oklahoma State Univ.; Oklahoma State Univ.; The College of New Jersey: Variation in resting metabolic rate across season, class, and year in the eastern collared lizard The metabolizable energy an animal assimilates must meet a variety of costs. Increasing the metabolic efficiency of processes associated with […]

BOWLIN, M.S.; WIKELSKI, M.C.; COCHRAN, W.W.; Princeton University; Princeton University; Illinois Natural History Survey: The relationship between individual morphology, atmospheric conditions, and inter-individual variation in heart rate and wingbeat frequency during natural migration in the Swainson�s Thrush (Catharus ustulatus) Migratory flight, though less costly than early theoretical models predicted, still represents a significant investment in […]

WILLIAMS, T.M.; Univ. of California, Santa Cruz: Taking lab energetics to the field: How the physiology of large, carnivorous mammals is shaping marine and terrestrial ecosystems Large mammalian predators by virtue of their body size, mobility, carnivorous feeding habits and endothermic costs have exceptionally high energetic demands in comparison to other animal groups. Although the […]
