Wing muscle function in the pigeon (Columba livia) during short free-flights
Meeting Abstract 51.2 Thursday, Jan. 6 Wing muscle function in the pigeon (Columba livia) during short free-flights BERG ROBERTSON, AM*; BIEWENER, AA; University of Houston; Harvard University angelabergrobertson@gmail.com To understand the different requirements of takeoff, midflight and landing, we compared the motor patterns of flight muscles in the pigeon during flight between two perches. We recorded muscle […]
Pectoralis contractile activity during WAIR and flight in pigeons
Meeting Abstract 51.3 Thursday, Jan. 6 Pectoralis contractile activity during WAIR and flight in pigeons JACKSON, Brandon E.*; TOBALSKE, Bret W.; DIAL, Kenneth P.; Univ. of Montana, Missoula brandon.jackson@mso.umt.edu Wing-assisted incline running (WAIR) in birds combines use of the wings and hindlimbs to ascend obstacles. It is a means of escape in precocial birds before they can […]
Neuromuscular Control of Yaw Turns in the Hawkmoth Manduca sexta
Meeting Abstract 51.1 Thursday, Jan. 6 Neuromuscular Control of Yaw Turns in the Hawkmoth Manduca sexta SPRINGTHORPE, D*; FERNANDEZ, MJ; HEDRICK, TL; Univ. of North Carolina at Chapel Hill; Univ. of North Carolina at Chapel Hill; Univ. of North Carolina at Chapel Hill dwight@email.unc.edu Recent models of turning in flapping flight suggest that yaw turns are highly […]
Molecular and structural evidence for temperature dependent elastic energy storage in Manduca sexta
Meeting Abstract 51.4 Thursday, Jan. 6 Molecular and structural evidence for temperature dependent elastic energy storage in Manduca sexta GEORGE, N.T.*; HSU, H.M.; IRVING, T.C.; DANIEL, T.L.; Univ. of Washington ntgeorge@u.washington.edu Heat production in locomotor muscles and surface heat loss leads to a temperature gradient. Thus in the dominant flight muscles driving wing depression (dorsolongitudinal muscles: DLM1) […]
Effects of temperature on in vitro muscle dynamics of chameleon feeding muscles
Meeting Abstract 51.5 Thursday, Jan. 6 Effects of temperature on in vitro muscle dynamics of chameleon feeding muscles ANDERSON, C.V.*; DEBAN, S.M.; Univ. South Florida, Tampa cvanders@mail.usf.edu Despite the strong effect of body temperature on muscle contractile velocity, and thus movement performance, chameleons are known to feed using high-powered ballistic tongue projection at low body temperature. In […]
The Effects of Serotonin on Leech Muscle Mechanics
Meeting Abstract 50.5 Thursday, Jan. 6 The Effects of Serotonin on Leech Muscle Mechanics GERRY, S.P.*; ELLERBY, D.J.; Wellesley College; Wellesley College sgerry@wellesley.edu The longitudinal body wall muscle of leeches (Hirudo verbana) supplies mechanical power during three distinct behaviors: swimming, crawling and suction feeding of blood. We quantified longitudinal muscle strain during these behaviors in vivo using […]
Forelimb muscle architecture of the American badger (Taxidea taxus) and groundhog (Marmota monax)
Meeting Abstract 50.6 Thursday, Jan. 6 Forelimb muscle architecture of the American badger (Taxidea taxus) and groundhog (Marmota monax). MOORE, A.L.*; BUTCHER, M.T.; Youngstown State Univ. almoore@student.ysu.edu The arrangement and orientation of muscle fibers reflect functional specializations of muscle. Relating muscle architecture with function is fundamental to understanding the roles of limb muscles. Limb muscles are often […]

PACE, CM*; MONROY, JM; METOYER, A; ALDRIDGE, C; WANG, J; NISHIKAWA, KC; Northern Arizona University; Northern Arizona University; Northern Arizona University; Northern Arizona University; Northern Arizona University; Northern Arizona University Cinnamon.Pace@nau.edu The protein titin is known to contribute to the elastic properties of […]
Diversification of triggerfish (Teleostei Balistidae) cranial shape and jaw biomechanics
Meeting Abstract 50.2 Thursday, Jan. 6 Diversification of triggerfish (Teleostei: Balistidae) cranial shape and jaw biomechanics MCCORD, Charlene *; WESTNEAT, Mark ; University of Chicago; Field Museum of Natural History cmccord@uchicago.edu The subdivided adductor mandibulae muscles of triggerfishes provide an excellent experimental model upon which to analyze the biomechanical consequences of differential oral jaw morphology. We surveyed […]
