Meeting Abstract 6.2  Wednesday, Jan. 4  Length, force and changes in the elastic behavior of active muscle. GILMORE, L. A.*; NISHIKAWA, K. C.; Northern Arizona University leslie.gilmore@nau.edu Previous studies have examined how muscle force and shortening velocity change with length changes in active muscle. However, few studies have examined how elastic behavior changes with muscle length. Using […]

Meeting Abstract 6.6  Wednesday, Jan. 4  Female pheromones modulate muscle activation patterns for pre-flight warm-up in male moths CRESPO, J. G.*; VCIKERS, N. J.; GOLLER, F.; University of Utah, Salt Lake City, Utah jose.crespo@utah.edu In Helicoverpa zea, the pheromone-mediated upwind flight of males is elicited by a two-component pheromone blend. Efficient upwind locomotion may require that moths […]

Meeting Abstract 6.10  Wednesday, Jan. 4  Contractile Properties and Myosin Expression in Swimming and Feeding Muscles of Centrarchid Fishes COUGHLIN, D. J.*; MISTRY, H.; CAMPION, L. A.; CHOI, S.; Widener Univ.; Widener Univ.; Widener Univ.; Widener Univ. djcoughlin@widener.edu In centrarchid fishes, such as bluegill and largemouth bass, the contractile properties of feeding and swimming muscles show different […]

Meeting Abstract 6.2  Friday, Jan. 4  Where’s the catch? Examining the catch mechanism in anuran jumping using inverse dynamics. ASTLEY, H. C.*; ROBERTS, T. J.; Brown University henry_astley@brown.edu Many animals use catapult mechanisms to produce extremely rapid movements for escape or prey capture, resulting in power outputs far beyond the limits of muscle. In these catapults, muscle […]

Meeting Abstract 6.6  Friday, Jan. 4  Three-dimensional joint mechanics and kinematics of jumping lizards OLBERDING, JP*; HIGHAM, TE; Univ. of California, Riverside; Univ. of California, Riverside jolbe001@ucr.edu Hindlimb kinematics are often examined and related to locomotor performance in lizards, but establishing a causal link between individual joint movements and whole-animal performance requires an understanding of joint mechanics. […]

Meeting Abstract 6.1  Friday, Jan. 4  The basic mechanics of pronking, bounding or frog-hopping �” the costs of pitching accounts for much of the diversity of fast quadrupedal gaits. USHERWOOD, JR; The Royal Veterinary College jusherwood@rvc.ac.uk Quadrupeds show a fascinating range of gaits, both between species and across speeds. Accounting for the selection of these gaits, and […]
