Meeting Abstract 9.6 Jan. 4 Changes in the mandible with age in carnivorans BINDER, W/J; Loyola Marymount University wbinder@lmu.edu As individuals age, skull morphology has been shown to change and reflect new force distributions. This type of change is especially interesting in carnivoran (members of the Order Carnivora) teeth and jaws, as feeding is so important and […]

Bite and grip performance in relation to killing behavior of North American accipiters and falcons
Meeting Abstract 9.4 Jan. 4 Bite and grip performance in relation to killing behavior of North American accipiters and falcons SUSTAITA, Diego*; HERTEL, Fritz; University of Connecticut; California State University, Northridge diego.sustaita@uconn.edu Raptors exhibit a wide diversity of attack strategies to disable and/or procure their prey, but ultimately kill using either their beaks or talons, or both. […]
Zig-zag locomotion alters shape of the murine limb bone diaphysis
Meeting Abstract 8.6 Jan. 4 Zig-zag locomotion alters shape of the murine limb bone diaphysis CARLSON, KJ*; JUDEX, S; Universitaet Zuerich; Stony Brook University carlson@aim.unizh.ch Many terrestrial animals incorporate rapid turns as a part of predator avoidance behavior, while arboreal animals encounter irregularly spaced substrates necessitating frequent turns during daily travel. Yet consequences of turning behavior on […]
Single Limb Forces in Jumping Frogs Implications for Limb Bone Loading
Meeting Abstract 8.2 Jan. 4 Single Limb Forces in Jumping Frogs: Implications for Limb Bone Loading BLOB, R.W.**; ESPINOZA, N.R.; PRUETTE, M.E.; WRIGHT, K.M.; CIRILO, S.R.; GOSNELL, J.S.; Clemson Univ.; Erskine College; Clemson Univ.; Clemson Univ.; Erskine College; Clemson Univ. rblob@clemson.edu The explosive jumps of frogs represent a dramatic locomotor behavior that might be expected to place […]
Reconstructing the loading environment of long bones from in vivo strain data
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 […]
