Meeting Abstract 49.1  Thursday, Jan. 5  What are walking and running, and why? Modeling optimization tested against gravity manipulation BERTRAM, JEA*; HASANEINI, SJ; University of Calgary jbertram@ucalgary.ca Simulated reduced gravity studies indicate a fundamental difference between human walking and running. The metabolic cost of running decreases directly with decrease in gravity and kinematic patterns change substantially and […]

Meeting Abstract 49.2  Thursday, Jan. 5  Walking in children – the story of an additional gait HUBEL, Tatjana Y*; USHERWOOD, James; Royal Veterinary College, London, UK; Royal Veterinary College, London, UK thubel@rvc.ac.uk Observations of walking in small children show that they move quite differently from what one would expect from downsized adults. Human adults are able to […]

Meeting Abstract 49.6  Thursday, Jan. 5  Gait transitions independent of speed in Lesser Egyptian Jerboa MOORE, TY*; COOPER, KL; BIEWENER, AA; Harvard Concord Field Station; Harvard Medical School; Harvard Concord Field Station tymoore@fas.harvard.edu Terrestrial locomotion is well documented and characterized by distinct gait transitions with increasing speed, which can optimize locomotor economy. Past research on bipeds indicates […]

Meeting Abstract 49.5  Thursday, Jan. 5  Describing gait transitions and the role of symmetry in control WILSHIN, S.D.*; HAYNES, G.C.; PORTEOUS, J.; SPENCE, A. J.; Royal Veterinary College; University of Pennsylvannia; Royal Veterinary College; Royal Veterinary College swilshin@rvc.ac.uk Gait transitions represent a natural perturbation away from steady state behaviour. As such they provide insight into how control […]

Meeting Abstract 49.4  Thursday, Jan. 5  Center of mass mechanics in the squirrel monkey Saimiri sciureus MILLER, CE*; GRANATOSKY, MC; O’NEILL, MC; BISHOP, KL; SCHMITT, D; Duke; Duke; Stony Brook University; Florida International University; Duke charlotte.miller@duke.edu The significance of whole body center of mass mechanics has been well studied in a range of bipedal and quadrupedal animals, […]

Meeting Abstract 48.5  Thursday, Jan. 5  Metabolic rates of an aquatic tardigrade, Dactylobiotus nuovo species. MEADE, Mark/E*; ROMANO, Frank; SEWELL, Susan; Jacksonville State University mmeade@jsu.edu We report here the use of a fiber optic, micro-respirometry system to monitor oxygen consumption rates in aquatic tardigrades. The system is highly sensitive (accuracy ±0.15% at 1% air saturation with a […]

Meeting Abstract 48.6  Thursday, Jan. 5  Metabolic physiology of the stream minnow, Campostoma oligolepis, inhabiting a polluted stream. CORDLE, M.E.*; MEADE, M.E.; NICHOLS, A.; Jacksonville State University; Jacksonville State University; Jacksonville State University mecordle@gmail.com Snow creek, Oxford, Alabama, was a victim of industrial heavy metal and PCB contamination in the 1970s. In those years, high concentrations of […]

Meeting Abstract 48.4  Thursday, Jan. 5  Do body composition drives winter variations of metabolic performance in black-capped chickadees (Poecile atricapillus)? PETIT, M*; VEZINA, F; Université du Québec à Rimouski; Université du Québec à Rimouski Magali.Petit@uqar.qc.ca Throughout the year, resident birds species living at northern latitudes exhibit changes in metabolic performance in response to seasonal variation in climatic […]

Meeting Abstract 48.3  Thursday, Jan. 5  Comparative metabolic rate and assimilation between an endemic rattlesnake and an invasive boa: implications for invasive species success GOESSLING, J.M.*; LUTTERSCHMIDT, W.I.; REINERT, H.K.; ODUM, R.A.; Sam Houston State University; Sam Houston State University and the Texas Research Institute for Environmental Studies; The College of New Jersey; Toledo Zoological Society goessling@auburn.edu […]

Meeting Abstract 48.1  Thursday, Jan. 5  Are intraspecific correlations between minimum and maximum metabolic output in birds consistent with the aerobic capacity model for the evolution of endothermy? SWANSON, David L*; THOMAS, Nathan E.; Univ. of South Dakota, Vermillion; Shippensburg Univ., Shippensburg, PA david.swanson@usd.edu The underlying assumption of the aerobic capacity model for the evolution of endothermy […]
