Meeting Abstract 86-1  Monday, Jan. 6 10:30 – 10:45  Effects of Heat Exposure on Antioxidant Expression and Redox Status in the American Oyster: A Laboratory Study RAHMAN, MS*; RAHMAN, MS; University of Texas Rio Grande Valley mdsadequr.rahman01@utrgv.edu Increasing atmospheric temperatures significantly influence the physiological functions in aquatic organisms, particularly the marine invertebrates which are extremely susceptible to […]

Meeting Abstract 86-6  Monday, Jan. 6 11:45 – 12:00  Body Size Changes Across Lizards and Crocodylians Correspond to Climatic Changes Through Deep Time ELSHAFIE, SJ; University of California, Berkeley selshafie@berkeley.edu http://www.sara-elshafie.com Climate is known to influence body size in living reptiles. However, this relationship has not been investigated over geologic time intervals, nor compared among higher-order groups […]

Meeting Abstract 86-3  Monday, Jan. 6 11:00 – 11:15  Beetle Pupae Show Tradeoff Between Metabolic Depression and Body Size in Response to Increased Temperature Mean and Variance FLEMING, JML*; CARTER, AW; SHELDON, KS; University of Tennessee, Department of Ecology and Evolutionary Biology ; University of Tennessee, Department of Ecology and Evolutionary Biology ; University of Tennessee, Department […]

Meeting Abstract 86.6  Tuesday, Jan. 6  How Center-of-Mass Dynamics of Hexapedal Locomotion Collapses to a Single Leg Template Model SEIPEL, Justin E*; FULL, Robert J; Univ. of California, Berkeley jseipel@berkeley.edu Many running animals and some robots produce similar center-of-mass motions and force patterns, like a pogo-stick. We found that the simplest pogo-stick template models explain steady-state motion, […]

Meeting Abstract 86.4  Tuesday, Jan. 6  Fitting the closed-loop dynamics of human running on a split-belt treadmill LEE, J.*; CHOI, J.T.; BASTIAN, A.J.; COWAN, N.J.; Johns Hopkins University; Johns Hopkins University; Johns Hopkins University; Johns Hopkins University jsl@jhu.edu Healthy humans alter their gait when walking or running on a split-belt treadmill (i.e. a treadmill that allows independent […]

Meeting Abstract 86.5  Tuesday, Jan. 6  Enhancement of legged robot speed on granular media using kinematics which promote solidification LI, C.*; UMBANHOWAR, P.; KOMSUOGLU, H.; KODITSCHEK, D.E.; GOLDMAN, D.I.; Georgia Insitute of Technology; Georgia Insitute of Technology; University of Pennsylvania; University of Pennsylvania; Georgia Insitute of Technology chen.li@gatech.edu Model locomotors (e.g. legged robots) have begun to achieve […]

Meeting Abstract 86.3  Tuesday, Jan. 6  Effect of varying weight and inertia on maximum attainable running speed in humans BOWTELL, M V*; TAN, H; WILSON, A M; Royal Veterinary College; Royal Veterinary College; Royal Veterinary College mbowtell@rvc.ac.uk Attainable running speed in humans has been presented as limited by the amount of force which can be withstood by […]

Meeting Abstract 86.1  Tuesday, Jan. 6  Compass-gait mechanics constrains walking speed in bipeds USHERWOOD, JR; The Royal Veterinary College jusherwood@rvc.ac.uk The constraints to maximum walking speed and the underlying cause of the walk-run transition remains controversial. However, the motions of the body and legs can be reduced to a few mechanical principles, which, if valid, impose simple […]

Meeting Abstract 86.2  Tuesday, Jan. 6  Biomechanics of foot strike in habitually barefoot versus shod runners LIEBERMAN, DE*; WERBEL, W; DAOUD, A; Harvard University danlieb@fas.harvard.edu Hominins evolved to run long distances, possibly as much as 2 million years ago, and until recently, humans ran either barefoot or in soft sandals with minimal cushioning or arch support. Here […]
