SANGER, T; GIBSON-BROWN, J; LOSOS, J; Washington Univ.: A developmental staging series for the lizard Anolis sagrei: a model system for the integration of development, evolution, and ecology. Integrating detailed studies of ecology and evolution with modern techniques of developmental genetics and molecular biology has the potential to be one of the most informative approaches […]

PORTER, S.S.; ECKERT, G.; BYRON, C.; FISHER, J.; University of California, Berkeley; University of Alaska, Southeast; University of Wisconsin, Madison; Moss Landing Marine Laboratory: A comparison of light traps and plankton tows We compared the efficiency of light-aggregation devices (light traps) and plankton tows for sampling crab larvae off the dock in Bartlett Cove, Glacier […]

ALURU, N*; VIJAYAN, M.M.; Univ. of Waterloo, Waterloo,ON: β-Naphthoflavone impacts interrenal corticosteroidogenesis in rainbow trout. The objective of the study was to investigate the impact of aryl hydrocarbon receptor (AhR) on interrenal steroidogenesis in rainbow trout (Oncorhynchus mykiss). We used β-napthoflavone (BNF) and α-napthoflavone (ANF) as agonist and antagonist of AhR, respectively. Fish were given […]

PIERCE, V.A.; MANGOGNA, J.; College of Staten Island/CUNY, NY: Urea Uptake Rates Respond to Changing Food Concentrations in Urea-Resistant and Susceptible Drosophila Populations We are using laboratory-selected D. melanogaster populations to investigate physiological mechanisms of toxin resistance. Larvae from replicate fly populations selected for resistance to 300 mM urea take up urea more slowly during […]

HILL, Peggy S M; HOFFART, Cara; BUCHHEIM, Mark; Univ. of Tulsa: Tracing relationships in the Gryllotalpidae Male prairie mole crickets (Gryllotalpa major) aggregate their acoustic burrows in a lek arena where they display for females. Individuals produce a loud advertisement call of chirps just at sunset on spring evenings in the south-central prairies of the […]

WU, S.H.*; MILLIGAN, C.L.; The University of Western Ontario, London: To eat or not to eat: The effect of food on metabolic recovery from a bout of exhaustive exercise in adult and juvenile rainbow trout white muscle Exhaustive exercise depletes muscle glycogen in both juvenile (~ 5g) and adult (~ 160g) trout. In adult fish, […]

ELWOOD, J.R.L.*; SPOTILA, J.R.; Drexel University, Philadelphia, PA; Drexel University, Philadelphia, PA: Tissue level hsp70 varies in laboratory acclimated and field acclimatized salamanders along geographic and climatic gradients Tissues from salamanders representing twelve populations of the Plethodon glutinosus complex varied in hsp70 levels measured using ELISA. We selected populations along both geographic and climatic gradients. […]
