MORSE, M. P.; University of Washington, Seattle: A Model for Undergraduate Biology Education Scholarship Numerous faculty members at universities and colleges have an abiding interest to improve biology learning for all undergraduates. Due to attention to research scholarship, maintaining active research laboratories and a general lack of time few of these faculty members are familiar […]

COUGHLIN, DJ; CAPUTO, ND; BOHNERT, KL; WEAVER, FE; Widener University; Widener University; Widener University; Widener University: Troponin-T and Longitudinal Variation in the Contractile Properties of Trout Muscle The red or aerobic muscle from the anterior of rainbow trout (Oncorhynchus mykiss) activates (generates force) more quickly than that from the posterior. An analysis of the expression […]

KING, A.J.*; ADAMO, S.A.; Dalhousie University, Halifax, Canada: Pulling for the greater good – elements of cuttlefish ventilatory and circulatory systems work together to circulate blood or to aid crypsis. Cephalopod blood is ~ 30% more viscous than human blood, and their hearts make up only 0.1 to 0.3% of their body weight (vs. 0.6% […]

BAUCHINGER, U; BIEBACH , H; University of Munich (LMU), Germany; Max-Planck-Institute for Ornithology: Phenotypic flexibility of organs and its releationship to body mass changes during migration Long-distance migration across ecological barriers necessitates substantial internal resources. Deposition of those resources can result in a doubling of body mass. Fat is the dominating fuel for flight, but […]

VILLARIN, J.J.*; SCHAEFFER, P.J.; CARLSEN, R.C.; Univ. of California, Davis; Washington Univ School of Medicine; Univ. of California, Davis: Non-Contractile Functions in Skeletal Muscle: Adaptation and Interactions Vertebrate skeletal muscle is most often discussed in the context of contractile function, which provides a broad range of functions: locomotion, breathing, posture, feeding, sound production, and so […]

KINSEY, Stephen T.; BOYLE, Kim-Laura; Univ. of North Carolina at Wilmington: Mitochondrial distribution and glycogen dynamics suggest diffusion constraints in muscle fibers of the blue crab, Callinectes sapidus. The scaling of mitochondrial distribution, citrate synthase activity and post-contractile glycogen recovery was examined in muscle fibers of the blue crab, Callinectes sapidus. The fast-twitch muscle fibers […]

M.*; ROURKE, B.C.; BENNETT, A.F.; HICKS, J.W.; University of California-Irvine; University of California-Irvine; University of California-Irvine; University of California-Irvine: Effects of aerobic exercise training on myosin heavy chain isoform expression in the Savannah Monitor Lizard Varanus exanthematicus Prior investigations indicate that reptiles do not demonstrate phenotypic plasticity in the oxygen transport system in […]

ERICKSON, J.R.; MOERLAND, T.S.; Florida State University; Florida State University: Calcium-binding characteristics of parvalbumin isolated from the Arctic cod (Boreogadus saida) The calcium-binding protein parvalbumin (PV) is highly abundant in muscle and is thought to sequester intracellular Ca2+ after a contraction, thus facilitating relaxation. The dissociation constant (Kd) of Ca2+ from PV isolated from the […]

BENOWITZ-FREDERICKS, Morgan; KITAYSKY, Alexander S.; HATCH, Scott A.; Univ. Alaska, Fairbanks; Univ. Washington, Seattle; Univ. Alaska, Fairbanks; U.S. Geological Survey, Alaska Science Center : Yolk androgens in Black-legged kittiwakes: Consequences of food supplementation Black-legged kittiwakes are seabirds that frequently face food shortages during reproduction. Siblicide resulting in loss of the beta chick reduces competition among […]
