DIAL, K.P; BUNDLE, M.W.; Univ. Montana, Missoula; Univ. Montana, Missoula: Wing-assisted incline running: Accelerometer and force plate data Birds are capable of orienting aerodynamic forces directed toward a sloped substrate, effectively acting like a spoiler on a race car, to improve traction. During wing-assisted incline running (WAIR), the hind limbs of gallinaceous birds generate the […]

The effects of incline on limb forces in a quadrupedal mammal
LAMMERS, A.R.; PARCHMAN, A.J.; EARLS, K.D.; BIKNEVICIUS, A.R.; REILLY, S.M.; STEVENS, N.J.; Ohio Univ., Athens: The effects of incline on limb forces in a quadrupedal mammal Animals habitually move on non-horizontal terrains yet most locomotion studies quantify movement on level substrates. Our goal was to compare substrate reaction forces in the fore- and hindlimbs of […]
Proximal muscle function during level and incline hopping in tammar wallabies
MCGOWAN, C.P.*; BIEWENER, A.A.; Concord Field Station, Harvard University: Proximal muscle function during level and incline hopping in tammar wallabies. MCGOWAN, C. P.* and BIEWENER, A. A. Concord Field Station, Harvard University, cmcgowan@oeb.harvard.edu Proximal muscle function during level and incline hopping in tammar wallabies. Kangaroos and wallabies are exceptional in their ability to minimize locomotor […]
Locomotion of lizards on inclines and perches Comparative three-dimensional hindlimb kinematics of an arboreal specialist (chameleon) and a terrestrial generalist
HIGHAM, T.E.*; JAYNE, B.C.; Univ. of Cincinnati; Univ. of Cincinnati: Locomotion of lizards on inclines and perches: Comparative three-dimensional hindlimb kinematics of an arboreal specialist (chameleon) and a terrestrial generalist Arboreal animals often traverse three-dimensional networks of narrow perches with variable inclines, but the effects of both incline and narrow surfaces on the locomotor movement […]
Ground Reaction Forces During Level, Incline, and Decline Trotting
DUTTO, D.J.*; HOYT, D.F.; WICKLER, S.J.; California State Polytechnic Univ., Pomona CA: Ground Reaction Forces During Level, Incline, and Decline Trotting Little is known of the relative contributions of quadruped forelimbs and hind limbs to locomotion up and down hills. Two runways, one level and one with a 5.7 deg slope were used to record […]
The paradox of palp removal in the spider Tidarren sysiphoides a performance advantadge
RAMOS, MM; IRSCHICK, D; CHRISTENSON, T; Tulane University, New Orleans,LA; Tulane University, New Orleans,LA; Tulane University, New Orleans,LA: The paradox of palp removal in the spider Tidarren sysiphoides: a performance advantadge? Autotomy, the casting off of a body part, has evolved independently in several groups of organisms, and is thought to increase the short-term fitness […]
Slipping on sandy slopes–physical determinants of antlion pit function
BOTZ, J.T.*; LOUDON, C.; BARGER, J.B.; OLAFSEN, J.S.; STEEPLES, D.W.; University of Kansas; University of Kansas; University of Kansas; University of Kansas; University of Kansas: Slipping on sandy slopes–physical determinants of antlion pit function The difficulty that insects have walking on inclined sand is used to advantage by antlions, which construct pits in sand for […]
Peristaltic Locomotion in Holothuroids (Echinodermata)
SPAIN, Diara D. *; KIER, W.M.; UNC Chapel Hill; UNC Chapel Hill: Peristaltic Locomotion in Holothuroids (Echinodermata) Although many vermiform soft-bodied invertebrates use a form of peristaltic locomotion, this mode of locomotion has not been widely studied. In particular, the kinematics of different forms of peristaltic locomotion have received little attention previously. Time-lapse videorecording was […]
Dynamics of cellular movements in the locomotion of the sponge Tethya wilhelma
NICKEL, M.*; VITELLO, M.; BR�MMER, F.; Biological Institute of University Stuttgart, Germany: Dynamics of cellular movements in the locomotion of the sponge Tethya wilhelma The globular sponge Tethya wilhelma SAR�, SAR�, NICKEL & BR�MMER 2001 (Porifera, Demospongiae, Hadromerida, � 5-30 mm) is capable of locomotion. Many sponges display very slow body dislocation, but several small […]
