GOLEMAN, W. L.*; GENTLES, B.A.; HU, F.; CARR, J. A.; Texas Tech Univ., Lubbock; Texas Tech Univ., Lubbock; Texas Tech Univ., Lubbock; Texas Tech Univ., Lubbock: Evidence that adult frogs are less responsive to the thyroid disrupting effects of ammonium perchlorate. Recent data suggest that environmentally relevant concentrations of ammonium perchlorate (AP) retard metamorphosis by […]

BANTA, M.R.*; VAN SANT, M.J.; BAKKEN, G.S.; University of Northern Colorado; Indiana State University; Indiana State University : Evidence for metabolic substitution in swimming mallard (Anas platyrhychos) ducklings Substitution is the energetic phenomenon by which endotherms use heat generated during an activity such as digestion or locomotion for thermoregulation. This heat would otherwise have to […]

PARK, A.*; MORTIMER, J.A.; WIBBELS, T.; Univ. of Alabama at Birmingham; Ministry of the Environment, Republic of the Seychelles; Univ, of Alabama at Birmingham: Evaluation of incubation temperatures in hawksbill sea turtle nests on islands in the Republic of the Seychelles. Sea turtles, like many reptiles, possess temperature-dependent sex determination (TSD). Hatchling sex ratios resulting […]

DODD, K.L.*; MURDOCK, C.A.; WIBBELS, T.; University of Alabama at Birmingham; University of Alabama at Birmingham; University of Alabama at Birmingham: Evaluation of aromatase mRNA levels in brain tissue during temperature-dependent sex determination in a turtle. Some reptiles exhibit temperature-dependent sex determination (TSD), in which the incubation temperature of the egg determines the sex of […]

MAROM, S.; WOJCIECHOWSKI , M.; KORINE, C.; PINSHOW, B.; BEN GURION UNIVERSITY OF THE NEGEV; BEN GURION UNIVERSITY OF THE NEGEV; BEN GURION UNIVERSITY OF THE NEGEV; BEN GURION UNIVERSITY OF THE NEGEV: Energy metabolism and water loss in two sympatric microchiropteran species – a day:night comparison In this study, we compared body temperature, metabolic […]

BOEHM, M.C.*; SECOR, S.M.; University of Alabama, Tuscaloosa; University of Alabama, Tuscaloosa: Energy budget models of specific dynamic action for the amphibians Ambystoma tigrinum and Bufo cognatus A substantial portion of an ectotherm�s energy expenditure can be attributed to specific dynamic action (SDA), the accumulated energy expended on meal digestion and assimilation. Therefore, an estimate […]

PEFFER, Ben J.; LAYNE, JR., Jack R.; Slippery Rock University, PA; Slippery Rock University, PA: Effects of tissue freezing on hemolymph K concentration and water distribution in caterpillars of Pyrrharctia isabella. Tissue freezing causes substantial osmotic flux of water from cells and reduces aerobic-based production of ATP. These events could disturb ion homeostasis inside the […]

DAW, K.J.; RODNICK, K.J.; Idaho State University: Effects of sex and feeding status on energy substrates in tissues of rainbow trout Recent studies in mammals highlight sex differences in energy metabolism. Diets for carnivorous fish like rainbow trout consist primarily of proteins and lipids, and these fish are thought, unlike mammals, to be relatively intolerant […]

PETERSON, B.C.; WALDBIESER, G.C.; BILODEAU, L.; USDA/ARS; USDA/ARS; USDA/ARS: Effects of recombinant bovine growth hormone (rbGH; Posilac) on growth and mRNA expression of IGF-I and IGF-II in channel catfish. Growth is a valued trait for cultivated fish. Identifying genes involved in regulating growth may prove important to selecting fish for efficient lean growth. Expression of […]
