Meeting Abstract P1.126 Jan. 4 Evaluating the phylogenetic significance of nematocyst ultrastructure for Cnidaria REFT, AJ; Ohio State Univ., Columbus ajreft@hotmail.com Nematocyst, intracellular capsules important for the capture of prey, defense against predators, and intraspecific aggression, are found in all cnidarians. Nematocysts vary in morphology, with more than 30 types currently recognized. However, because variation in nematocyst […]

Epinephrine Does Not Promote Cardiac Glycogen Depletion In Vitro In Rainbow Trout
Meeting Abstract P1.74 Jan. 4 Epinephrine Does Not Promote Cardiac Glycogen Depletion In Vitro In Rainbow Trout SORENSEN, Olav J.*; BATTIPROLU, Pavan K.; RODNICK, Kenneth J.; Idaho State University; Idaho State University; Idaho State University soreolav@isu.edu During stress, including environmental hypoxia and elevated swimming activity, circulating epinephrine increases in fishes. In mammals, it is known that epinephrine […]
Environmental and genetic effects on structural coloration in nestling bluebirds
Meeting Abstract P1.122 Jan. 4 Environmental and genetic effects on structural coloration in nestling bluebirds SIEFFERMAN, L.M.*; MCGLOTHLIN, J.W.; HILL, G.E.; Indiana University lsieffer@indiana.edu Sexually selected traits are expected to exhibit genetic variation and to be honest indicators of individual quality. Eastern bluebirds (Sialia sialis) have brilliant, structural blue-ultraviolet coloration that has been shown to be sexually […]

Meeting Abstract P1.92 Jan. 4 Effects of temperature acclimation on oxidative capacities and antioxidant enzymes in selected tissues from killifish, Fundulus heteroclitus GRIM, J.M.*; MILES, D.R.B.; CROCKETT, E.L.; Ohio University; Ohio University; Ohio University grimj@ohio.edu Changes in lipid composition coupled with an expansion of oxidative capacities may leave biological membranes at an elevated risk of lipid peroxidation […]
Effects of ontogenetic increases in size on muscle strain and activation patterns during goat locomotion
Meeting Abstract P1.44 Jan. 4 Effects of ontogenetic increases in size on muscle strain and activation patterns during goat locomotion BONVINI, Lauren*; GILLIS, Gary; Mount Holyoke College; Mount Holyoke College ggillis@mtholyoke.edu Size is known to have important consequences for the structural design and functional capacity of different physiological systems. The musculoskeletal system has been particularly well studied, […]

Meeting Abstract P1.65 Jan. 4 Effects of differing oxygen incubation levels on the physiology of ductus arteriosi in near-term chicken embryos COPELAND, J.M.*; DZIALOWSKI, E.M.; University of North Texas, Denton JenniferM_Copeland@yahoo.com The developing avian embryo has a left ductus arteriosus (LDA) and a right ductus arteriosus (RDA) that shunt pulmonary blood away from the lungs and to […]
Effects of atmospheric oxygen levels on embryonic growth of the American alligator
Meeting Abstract P1.40 Jan. 4 Effects of atmospheric oxygen levels on embryonic growth of the American alligator OWERKOWICZ, T.*; HICKS, J.W.; University of California, Irvine; University of California, Irvine towerkow@uci.edu Adequate oxygen supply to the embryo is necessary for normal growth and development. Hypoxia is known to constrain embryonic growth of endothermic vertebrates, but little data are […]
Ecdysone signaling controls fat-body remodeling during metamorphosis in Drosophila melanogaster
Meeting Abstract P1.7 Jan. 4 Ecdysone signaling controls fat-body remodeling during metamorphosis in Drosophila melanogaster BOND, N; HOSHIZAKI, DK*; Univ. of Nevada Las Vegas; Univ. of Nevada Las Vegas dkhosh@clark.nscee.edu The major signal for entry into metamorphosis is a high-titer pulse of the steroid hormone 20-hydroxy-ecdysone (herein referred to as Ecdysone) which triggers the induction of growth […]
