Meeting Abstract 42.6 Jan. 6 Elastic properties of muscle during active shortening MONROY, J.A.*; GILMORE, L.A.; KREBS, L.; LAPPIN, A.K.; LINDSTEDT, S.L.; PIEROTTI, D.J.; NISHIKAWA, K.C.; Northern Arizona University Jenna.Monroy@nau.edu Recent work demonstrates that muscles themselves store elastic energy during isometric tetanus. When the force is reduced rapidly, muscles recoil elastically. Elastic recoil of muscle contributes to […]

Anatomy and Histochemistry of Golden Eagle Flight Muscles
Meeting Abstract 42.5 Jan. 6 Anatomy and Histochemistry of Golden Eagle Flight Muscles MEYERS, R.A.*; MCFARLAND, J.C.; Weber State University, Ogden, UT; Weber State University, Ogden, UT rmeyers@weber.edu Previous research in our laboratory and elsewhere has show that soaring birds such as albatrosses, vultures and pelicans possess a slow-contracting deep layer to the pectoralis that is presumed […]
Tail-induced Air-righting Maneuver Reorients Geckos
Meeting Abstract 42.3 Saturday, Jan. 5 Tail-induced Air-righting Maneuver Reorients Geckos. JUSUFI, A.**; REVZEN, S.; FULL, R.J.; Univ. of California, Berkeley ardianj@berkeley.edu Despite morphological and behavioral adaptations to enhance stability during climbing (Jusufi et al., 2007), falls occur frequently among arboreal reptiles. We observed that rapidly climbing geckos (Cosymbotus platyurus) that fell or jumped off the wall […]
Losing Stability Tail loss and jumping in the lizard Anolis carolinensis
Meeting Abstract 42.5 Saturday, Jan. 5 Losing Stability: Tail loss and jumping in the lizard Anolis carolinensis BONVINI, LA*; IRSCHICK, D; GILLIS, GB; Mount Holyoke College; Univ. of Massachusetts, Amherst; Mount Holyoke College ggillis@mtholyoke.edu Lizard tails are functionally versatile and play critical roles in energy storage, balance, and sexual display. However, in many species the tail can […]
Effect of Variation in Length and Width on Single Seta Force in Geckos
Meeting Abstract 42.1 Saturday, Jan. 5 Effect of Variation in Length and Width on Single Seta Force in Geckos PEATTIE, AM*; FULL, RJ; Univ. of California, Berkeley; Univ. of California, Berkeley apeattie@berkeley.edu Adhesive structures on gecko feet exhibit considerable morphological variation. To test the effect of this variation on adhesive performance, we measured single-seta force in eight […]
Dynamic response to sliding in isolated gecko setal arrays
Meeting Abstract 42.2 Saturday, Jan. 5 Dynamic response to sliding in isolated gecko setal arrays GRAVISH, NICK*; WILKINSON, MATT; AUTUMN, KELLAR; Lewis & Clark College; Lewis & Clark College; Lewis & Clark College gravish@lclark.edu Under most conditions, geckos adhere strongly and have no difficulty maintaining adhesive contact. Casual observations indicate that geckos can run on inverted surfaces […]
Do hindlimb joints serve multiple functions during jumping in the Cuban tree frog
Meeting Abstract 42.4 Saturday, Jan. 5 Do hindlimb joints serve multiple functions during jumping in the Cuban tree frog? HSIEH, S.T.*; ROBERTS, T.J.; Harvard University; Brown University sthsieh@post.harvard.edu Cuban tree frogs (Osteopilus septentrionalis) are some of nature�s best vertebrate jumpers, capable of exceeding 20 body lengths in one leap. Although these jumps are by necessity characterized as […]
The role of HSP70 expression in locomotion – Reduced sprint speeds after heat stress in Sceloporus occidentalis
Meeting Abstract 42.5 Monday, Jan. 5 The role of HSP70 expression in locomotion – Reduced sprint speeds after heat stress in Sceloporus occidentalis. MCMILLAN, D.M.*; REES, B; IRSCHICK, D; UMass Amherst; University of New Orleans; UMass Amherst mcmillan@bio.umass.edu The Western fence lizard, Sceloporus occidentalis is a geographically widespread lizard occurring throughout the western United States across many […]
