Meeting Abstract 100.4 Wednesday, Jan. 7 Does diet quality alter the temperature-size rule? DIAMOND, S.E.*; KINGSOLVER, J.G.; University of North Carolina, Chapel Hill; University of North Carolina, Chapel Hill sdiamond@email.unc.edu How does variation in diet quality and temperature interact to affect survival, size and development time in herbivores? We conducted laboratory experiments with the tobacco hornworm, Manduca […]

Distal-less regulates developmental stability in the flour beetle, Tribolium castaneum
Meeting Abstract 99.1 Wednesday, Jan. 7 Distal-less regulates developmental stability in the flour beetle, Tribolium castaneum SUZUKI, Yuichiro*; SQUIRES, Diego C.; RIDDIFORD, Lynn M.; Wellesley College, Wellesley, MA; University of Washington, Seattle, WA; Janelia Farms, Janelia Farm, Howard Hughes Medical Institute, Ashbrun, VA ysuzuki@wellesley.edu Organisms have an amazing capacity to develop normally in the face of environmental […]
Characterizing the biological activity of estradiol sulfate during embryonic development Inactive steroid metabolite or precursor for steroid production
Meeting Abstract 99.2 Wednesday, Jan. 7 Characterizing the biological activity of estradiol sulfate during embryonic development: Inactive steroid metabolite or precursor for steroid production? PAITZ, RT*; BOWDEN, RM; Illinois St. Univ.; Illinois St. Univ. rpaitz@ilstu.edu Steroids are known to play an important role in directing sexual differentiation of vertebrates. Traditionally, research has focused on the embryonic gonads […]
Trade-offs between force and accuracy in human performance
Meeting Abstract 98.6 Wednesday, Jan. 7 Trade-offs between force and accuracy in human performance IRSCHICK, DJ*; HENNINGSEN, J; University of Massachusetts at Amherst irschick@bio.umass.edu A simple yet profound functional trade-off involves force and accuracy. High levels of force would seem to necessarily result in lower levels of accuracy, and vice versa, but testing this functional trade-off is […]
The series elastic shock absorber tendon elasticity reduces peak muscle forces during active lengthening
Meeting Abstract 98.9 Wednesday, Jan. 7 The series elastic shock absorber: tendon elasticity reduces peak muscle forces during active lengthening ROBERTS, T.J.*; AZIZI, E.; Brown University thomas_roberts@brown.edu Tendons store and release mechanical energy when force is applied to them. This spring-like behavior can conserve muscle mechanical power for cyclical activities like running, or amplify it for high-power […]
The kinetics and kinematics of human performance Trade-offs between force and accuracy
Meeting Abstract 98.7 Wednesday, Jan. 7 The kinetics and kinematics of human performance: Trade-offs between force and accuracy ALMEDIA, Suellen*; IRSCHICK, Duncan; University of Massachusetts at Amherst; University of Massachusetts at Amherst salmeida@student.umass.edu The production of maximum force during difficult motor tasks is presumed to trade-off with accuracy, but we know relatively little about the nature of […]
Muscle performance during frog jumping influence of series elasticity on muscle length-tension behavior
Meeting Abstract 98.10 Wednesday, Jan. 7 Muscle performance during frog jumping: influence of series elasticity on muscle length-tension behavior AZIZI, E*; ROBERTS, TJ; Brown University; Brown University manny_azizi@brown.edu The remarkable jumping ability of most frogs cant be explained solely from muscle properties. The maximum power available from hindlimb muscles has been shown to be insufficient to power […]
