Neuromechanical events that trigger ballistic prey capture in toads
LAPPIN, A.K.*; PILARSKI, J.Q.; PIEROTTI, D.J.; HEMPLEMAN, S.C.; NISHIKAWA, K.C.; Northern Arizona University: Neuromechanical events that trigger ballistic prey capture in toads. Ballistic tongue projection in toads is an extremely rapid movement that depends upon the storage and recovery of elastic strain energy. Elastic energy is stored in the depressor mandibulae muscles and in-series connective […]
Forelimb and caudopelvic function during takeoff in Rana pipiens
ESSNER, R.L.*; NAUWELAERTS, S.; ROME, L.C.; University of Pennsylvania; University of Pennsylvania; University of Pennsylvania: Forelimb and caudopelvic function during takeoff in Rana pipiens The forelimbs of frogs are thought to play balancing or positioning roles during takeoff. However, they may also be important in raising the center of mass (CoM) via forelimb extension prior […]
Bioballistics The Scaling of Prelaunch Acceleration and Subsequent Trajectories
VOGEL, S; Duke University: Bioballistics: The Scaling of Prelaunch Acceleration and Subsequent Trajectories Biological projectiles, from spores to leaping mammals, range over 100,000-fold in length. If force available varies with length squared and projectile mass with length cubed, then acceleration should scale inversely with length. Thus the prodigious accelerations of small ones (approaching 1,000,000 g) […]
Allometry of avian flight performance contribution of legs and wings during maximal burst takeoff and vertical flight
JACKSON, B.E.*; DIAL, K.P.; Univ. of Montana, Missoula; Univ. of Montana, Missoula: Allometry of avian flight performance: contribution of legs and wings during maximal burst takeoff and vertical flight Previous work on bird takeoff and vertical flight has been relatively limited either by the selection of the performance variables or by the phylogenetic scope of […]
Swimming posture switches from visual to vestibular control in developing larval southern flounder
Meeting Abstract 56.1 Jan. 6 Swimming posture switches from visual to vestibular control in developing larval southern flounder SCHREIBER, A.M.; Carnegie Institution, Embryology schreiber@ciwemb.edu Flatfish transform from symmetric, upright-swimming larvae into asymmetric juveniles that swim on one side. Lateralized posture develops independent of eye position during metamorphosis, suggesting strong vestibular, as opposed to visual, involvement. This study […]
Relaxed selective constraints on Hox clusters of ray-finned fishes Patterns and frequencies of mobile DNA element insertions
Meeting Abstract 56.4 Jan. 6 Relaxed selective constraints on Hox clusters of ray-finned fishes: Patterns and frequencies of mobile DNA element insertions RAINCROW, J.R.*; GAO, L.Z.; AMEMIYA, C.; CHIU, C.H.; Rutgers University; Rutgers University; VMRC, Seattle, Washington; Rutgers University raincrow@biology.rutgers.edu Hox genes, which share sequence homology with the Hom-C genes of Drosophila, originated early in metazoan evolution […]
Position, distance and hydrodynamic effects on fertilization success of the green sea urchin Strongylocentrotus droebachiensis
Meeting Abstract 56.3 Jan. 6 Position, distance and hydrodynamic effects on fertilization success of the green sea urchin Strongylocentrotus droebachiensis. KREGTING, L.T*; YUND, P.O; THOMAS, F.I.M; GRABOWSKI, R.C; University of New England; University of New England; University of Hawaii; University of South Florida lkregting@une.edu The distance and location between free spawning invertebrates such as sea urchins can […]
