Meeting Abstract 57.4  Monday, Jan. 5 14:15  Injury, infaunal activity and soft sediment community ecology: New insights and new directions LINDSAY, S.M.; University of Maine, Orono slindsay@maine.edu In 1984, Sally Woodin reported the effects of injury (posterior segment or feeding palp loss) on activity of arenicolid, maldanid and spionid polychaetes [Biol Bull 166:558-573]. Tissue loss reduced defecation […]

Meeting Abstract 57.6  Monday, Jan. 5 14:45  Discussion

Meeting Abstract 57.1  Monday, Jan. 5 13:30  Biogeography of range edges in intertidal populations – effects of larval transport WETHEY, DS; Univ South Carolina, Columbia wethey@biol.sc.edu The barnacle Semibalanus balanoides and the polychaetes Diopatra neapolitana and Diopatra biscayensis have multiple geographic limits in France, Spain, and Portugal. Population densities near range edges decay exponentially with distance from […]

Meeting Abstract 57-2  Tuesday, Jan. 5 10:30  Scaling of power and work accounts for scaling of animal posture, and walking and running mechanics from toddler to adult. USHERWOOD, JR*; HUBEL, TY; The Royal Veterinary College, London; The Royal Veterinary College, London jusherwood@rvc.ac.uk https://sites.google.com/site/jimusherwoodresearch/ Larger terrestrial animals tend to support their weight with more upright limbs. This makes […]

Meeting Abstract 57-5  Tuesday, Jan. 5 11:15  Ontogenetic changes in locomotor mechanics and performance in fire salamanders RANKIN, JW*; VELO-ANTÓN, G; NICIEZA, AG; HUTCHINSON, JR; The Royal Veterinary College, UK; University of Porto, Portugal; University of Oviedo, Spain; They Royal Veterinary College, UK jrankin@rvc.ac.uk Salamanders undergo a highly derived developmental cycle that requires a transition from an […]

Meeting Abstract 57-4  Tuesday, Jan. 5 11:00  Limbless Locomotion Control in Unstructured Terrains TRAVERS, M*; SCHIEBEL, P; GOLDMAN, D; CHOSET, H; Carnegie Mellon; Georgia Tech; Georgia Tech; Carnegie Mellon mtravers@andrew.cmu.edu We are interested in uncovering the fundamental elements that enable limbless locomotors to move in unstructured terrestrial environments. This is challenging because while it is possible to […]

Meeting Abstract 57-3  Tuesday, Jan. 5 10:45  Estimating predictive dynamical models of legged locomotion from data BANJANIN, B*; BURDEN, SA; MOORE, TY; REVZEN, S; FULL, RJ; University of Washington, Seattle; University of Washington, Seattle; Harvard University; University of Michigan, Ann Arbor; University of California, Berkeley sburden@uw.edu We seek dynamical models of legged locomotion that provide quantitative predictions […]

Meeting Abstract 57-7  Tuesday, Jan. 5 11:45  Center of mass dynamics in the bipedally running brown basilisk (Basiliscus vittatus) FATH, M.A.*; HSIEH, S.T.; Temple University; Temple University tuf77090@temple.edu It is well-known that among terrestrial animals with parasagittal limb postures, center of mass (CoM) potential and kinetic energies fluctuate out-of-phase when walking, but fluctuate in-phase during running. Lizards […]

Meeting Abstract 57-6  Tuesday, Jan. 5 11:30  Alligator (Alligator mississipiensis) shoulder girdle motion during walking BAIER, D*; MORITZ, S; CARNEY, R; GARRITY, B; Providence College; Brown University; Brown University; Providence College dbaier@providence.edu Alligators have played a significant role in evolutionary studies of archosaurs. Given that several major shifts in forelimb function (including 2 of the 3 origins […]

Meeting Abstract 57-1  Tuesday, Jan. 5 10:15  3D kinematics and pelvic motion during walking locomotion in the red-legged running frog (Kassina maculata) COLLINGS, AJ*; PORRO, LB; RICHARDS, CT; Royal Veterinary College, United Kingdom; Royal Veterinary College, United Kingdom; Royal Veterinary College, United Kingdom ajcollings@rvc.ac.uk Kassina maculata retain the characteristic anuran body plan and jumping ability, however employ […]
