Meeting Abstract 8.10 Jan. 4 Reconstructing the loading environment of long bones from in vivo strain data DEMES, Brigitte; Stony Brook University bdemes@ms.cc.sunysb.edu The in vivo strain measurement method has proven to be an important tool for exploring the interface between skeletal loading and bone shape. Strains recorded from multiple sites around the circumference of long bone […]

Quadrupedal walking, trotting, and galloping reveal different collisional patterns as assessed by center of mass velocity and whole-body ground reaction force vectors
Meeting Abstract 8.8 Jan. 4 Quadrupedal walking, trotting, and galloping reveal different collisional patterns as assessed by center of mass velocity and whole-body ground reaction force vectors LEE, David V.; Harvard University dvlee1@gmail.com The collisional perspective of Ruina, Bertram, and Srinivasan (2005) demonstrates that energetic losses can be reduced by employing several, sequenced collisions, instead of just […]
Musculoskeletal scaling of the hindlimb of kangaroos and wallabies (Superfamily Macropodoidea)
Meeting Abstract 8.3 Jan. 4 Musculoskeletal scaling of the hindlimb of kangaroos and wallabies (Superfamily Macropodoidea) MCGOWAN, C. P.*; SKINNER, J.; BIEWENER, A.A.; University of Colorado at Boulder; University of South Australia; Harvard University mcgowac@colorado.edu This study seeks to extend prior analysis of the locomotor mechanics and physiology of marsupial hopping by examining how the hindlimb musculoskeletal […]
Mechanics of dog walking compared with a passive, stiff-limbed, 4-bar linkage model, and their collisional implications
Meeting Abstract 8.7 Jan. 4 Mechanics of dog walking compared with a passive, stiff-limbed, 4-bar linkage model, and their collisional implications USHERWOOD, J.R.; The Royal Veterinary College, London jusherwood@rvc.ac.uk This study presents a simple stiff-limbed passive model of quadrupedal walking, compares mechanics predicted from the model with those observed from forceplate measurements of walking dogs, and considers […]
Maneuvering Obstacles on a Treadmill by Hopping Kangaroo Rats, Dipodomys ordii
Meeting Abstract 8.4 Jan. 4 Maneuvering Obstacles on a Treadmill by Hopping Kangaroo Rats, Dipodomys ordii HYDE, Martha L.; West Texas A&M Univ, Canyon mhyde@mail.wtamu.edu The unpredictability of kangaroo rat locomotion is remarkably adapted to predator avoidance. Neural control mechanisms may allow for these rodents to effectively elude predators and still maneuver in a habitat that can […]
Limb Bone Strain Rates Across Diverse Locomotor Modes Hopping, Jumping and Walking
Meeting Abstract 8.1 Jan. 4 Limb Bone Strain Rates Across Diverse Locomotor Modes: Hopping, Jumping and Walking. CIRILO, S.R.*; ESPINOZA, N.R.; PRUETTE, M. E.; WRIGHT, K. M.; GOSNELL, J. S.; BUTCHER, M. T.; BLOB, R.W.; Erskine College; Erskine College; Clemson Univ.; Clemson Univ.; Clemson Univ.; Clemson Univ.; Clemson Univ. scirilo@erskine.edu Previous studies have found that when bones […]
Is arm swing active or passive during human walking and running
Meeting Abstract 8.11 Jan. 4 Is arm swing active or passive during human walking and running? PONTZER, Herman*; RAICHLEN, David A.; LIEBERMAN, Daniel E.; Washington University; University of Arizona; Harvard University hpontzer@artsci.wustl.edu Humans habitually swing their arms in phase with the contralateral leg during walking and running. This arm motion is generally thought to counteract the torque […]
External joint work modulation in goats during climbing jumps
Meeting Abstract 8.5 Jan. 4 External joint work modulation in goats during climbing jumps YOO*, E. H.*; LEE, D. V.; BIEWENER, A. A.; Harvard University, Concord Field Station edwinyoo@eecs.harvard.edu We wish to understand how multi-jointed legs are able to meet different terrain conditions and mechanical demands during vertical climbing jumps. We recorded ground reaction forces and hindlimb […]
Strain environment, bone histomorphology, and growth in the emu femur and tibiotarsus
Meeting Abstract 8.1 Thursday, Jan. 3 Strain environment, bone histomorphology, and growth in the emu femur and tibiotarsus MAIN, Russell P; Cornell University rpm74@cornell.edu A close relationship between skeletal form and mechanics has long been hypothesized. However, many studies have only examined these relationships in adult animals, while skeletal morphology is likely influenced by interactions between skeletal […]
Skeletal Development of the Vertebral Column in the Miniature Hylid Frog Acris crepitans, with Comments on Vertebral Anomalies
Meeting Abstract 8.5 Thursday, Jan. 3 Skeletal Development of the Vertebral Column in the Miniature Hylid Frog Acris crepitans, with Comments on Vertebral Anomalies PUGENER, L.A.; MAGLIA, A.M.*; Missouri S&T, Rolla; Missouri S&T, Rolla magliaa@umr.edu Although the vertebral column of anurans has received much attention in the last 150 years, few detailed studies exist of their skeletal […]
