Meeting Abstract 43.5  Jan. 6  SEX DIFFERENCES IN TELEOST CARDIAC BIOCHEMISTRY AND PHYSIOLOGY: WHAT HAVE WE BEEN MISSING? BATTIPROLU, Pavan K*; FARRAR, Richard S; HARMON, Kelli J; PIERSON, Nicholas S; RODNICK, Kenneth J; Idaho State University battpava@isu.edu Unlike numerous mammalian studies, studies of cardiac physiology and metabolism in fishes have paid little attention to sex or the […]

Meeting Abstract 43.3  Jan. 6  Protein Conservation in Spontaneous and Facultative Hibernators: the White-tailed Prairie Dog (Cynomys leucurus) and the Black-tailed Prairie Dog (Cynomys ludovicianus) COTTON, C.J.; University of Wyoming, Laramie ccotton@uwyo.edu White-tailed prairie dogs are spontaneous hibernators that undergo regular, low temperature torpor bouts throughout the winter, while black-tailed prairie dogs are facultative hibernators that utilize […]

Meeting Abstract 43.4  Saturday, Jan. 5  Turning Mechanics in Running Goats MORENO, C.A.**; BIEWENER, A.A.; Harvard University; Harvard University cmoreno@oeb.harvard.edu Terrestrial animals frequently must execute vigorous running turns, especially during predator-prey interactions. Though this behavior is critical for survival and places extreme demands on the musculoskeletal system, the mechanics of turning are not well understood. Despite recent […]

Meeting Abstract 43.3  Saturday, Jan. 5  Testing the generality of the cross-couplet locomotor system in marsupials REILLY, S. M.*; WHITE, T.D.; MCELROY, E.J.; Ohio University; Buffalo State College; Ohio University reilly@ohiou.edu Extant placental mammals differ from marsupials and many more basal mammalian groups in having �epipubic� bones projecting into the abdominal wall. Previously we showed that these […]

Meeting Abstract 43.1  Saturday, Jan. 5  Ontogeny of joint mechanics in squirrel monkeys (Saimiri boliviensis) YOUNG, J. W.; Univ. of Texas, Austin jesse.young@mail.utexas.edu Ontogenetic studies of a small, yet diverse, mammalian sample have shown negative allometry of bony lever arms, suggesting developmental declines in effective mechanical advantage (EMA: i.e., muscle moment arm/substrate reaction moment arm). Increased EMA […]

Meeting Abstract 43.6  Saturday, Jan. 5  Linking leg morphology, gait, whole-body and individual limb mechanics in terrestrial locomotion MCELROY, Eric J*; REILLY, Stephen M; Ohio University; Ohio University em386403@ohiou.edu Terrestrial locomotion occurs when the musculoskeletal system moves the legs producing coordinated footfall patterns (gaits), which output forces to the substrate resulting in center of mass movement (mechanics). […]

Meeting Abstract 43.2  Saturday, Jan. 5  Functional significance of plantigrade foot posture in humans: implications to the evolution of foot posture in great apes CUNNINGHAM, CB*; CARRIER, DR; University of Utah; University of Utah c.cunningham@utah.edu Plantigrade foot posture, in which the heel contacts the substrate during a step, is a derived character of great apes. We used […]

Meeting Abstract 43.5  Saturday, Jan. 5  A Clock-Controlled Hip-Torqued Model for Locomotion SEIPEL, Justin*; FULL, Robert J; Univ. of California, Berkeley jseipel@berkeley.edu Simple spring-mass models have been used to describe net center of mass forces and motions of a diverse array of animals and robots. For ranges of behavior realistic to animals and robots, classic uncontrolled and […]

Meeting Abstract 43.6  Monday, Jan. 5  The aerodynamic body drag of Drosophila melanogaster PEEK, M.Y.*; DICKSON, W.B.; DICKINSON, M.H.; California Institute of Technology; California Institute of Technology; California Institute of Technology martin@caltech.edu Research in Drosophila melanogaster aerodynamics has provided key insights in understanding how small insects fly. In many previous studies, dynamically-scaled models of flapping wings have […]

Meeting Abstract 43.1  Monday, Jan. 5  Integrating locomotor mechanics and transport costs in a free-ranging gliding mammal BYRNES, G*; LIM, N; SPENCE, A. J.; Univ, of California, Berkeley; National Univ. of Singapore; Royal Veterinary College byrnes@berkeley.edu Gliding has evolved independently at least six times in mammals. One hypothesis for the origin of gliding is that it is […]
