Meeting Abstract 122.2 Monday, Jan. 7 Histamine functions and distribution in gastrulation and skeletogenesis of the sea urchin S. purpuratus NGUYEN, J; HEYLAND, A*; University of Guelph, Guelph aheyland@uoguelph.ca Earlier studies established a novel function of histamine signaling (HA) in metamorphic competence of the sea urchin Strongylocentrotus purpuratus. Preliminary results suggests that several neuron like cells synthesize […]

Gene interactions in the sex differentiation pathway of Oncopeltus fasciatus (Heteroptera)
Meeting Abstract 122.4 Monday, Jan. 7 Gene interactions in the sex differentiation pathway of Oncopeltus fasciatus (Heteroptera) LASLO, M*; ANGELINI, DR; American University; Colby College mlaslo09@gmail.com The regulation and development of sex is a classic subject in developmental biology. The biological importance of sex suggests that sex determination mechanisms could be conserved among sexually reproducing species; however, […]
The soft serve What tennis players can tell us about optimal performance in vertebrates
Meeting Abstract 122.4 Tuesday, Jan. 7 14:15 The soft serve: What tennis players can tell us about optimal performance in vertebrates WILSON, R S*; BROWN, C; WHEATLEY, R; University of Qld; University of Qld; University of Qld r.wilson@uq.edu.au Intuitively, we expect animals to use their maximum locomotor capabilities during key survival, reproductive and foraging behaviours – yet […]
Phase driven models of unperturbed locomotion
Meeting Abstract 122.5 Tuesday, Jan. 7 14:30 Phase driven models of unperturbed locomotion WILSHIN, S*; REVZEN, S; Royal Veterinary College; University of Michigan swilshin@rvc.ac.uk A major paradigm in contemporary biomechnics is the use of perturbation studies to probe animal movement. Such studies either implicitly or explicitly compare perturbed animal motions to some estimate of how an unperturbed […]
How do movement speed and terrain visibility influence neuromuscular control of bipedal locomotion
Meeting Abstract 122.1 Tuesday, Jan. 7 13:30 How do movement speed and terrain visibility influence neuromuscular control of bipedal locomotion? GORDON, J.C.*; RANKIN, J.W.; WILSON, A.M.; DALEY, M.A.; Royal Veterinary College, UK; Royal Veterinary College, UK; Royal Veterinary College, UK; Royal Veterinary College, UK jcgordon@rvc.ac.uk Bipedal locomotion requires dynamic stability accomplished via complex interactions of sensory information, […]
Ground-bird running in non-rigid terrain deducing task-level priorities in locomotion
Meeting Abstract 122.2 Tuesday, Jan. 7 13:45 Ground-bird running in non-rigid terrain: deducing task-level priorities in locomotion HUBICKI, C*; SPROEWITZ, A; HURST, J; DALEY, M; Oregon State University; Royal Veterinary College; Oregon State University; Royal Veterinary College hubickic@onid.orst.edu Terrestrial animals including ground birds regularly traverse terrain of irregular geometry and rigidity. We postulate that these diverse behaviors […]
Developmental plasticity of locomotor morphology in an animal model for the quadrupedal-to-bipedal transition
Meeting Abstract 122.3 Tuesday, Jan. 7 14:00 Developmental plasticity of locomotor morphology in an animal model for the quadrupedal-to-bipedal transition FOSTER, AD; University of Arizona adfoster@email.arizona.edu The evolution of bipedalism in the human lineage involved significant changes in musculoskeletal morphology to accommodate the locomotor shift from quadrupedalism to upright walking. However, the evolutionary mechanisms that underpin this […]
Bad Posture and its Effects on the Neck and Shoulder Suspension Apparatus of Humans A 3D Biomechanical Analysis
Meeting Abstract 122.6 Tuesday, Jan. 7 14:45 Bad Posture and its Effects on the Neck and Shoulder Suspension Apparatus of Humans: A 3D Biomechanical Analysis OSBORN, M.L.*; GE, J.; MELANCON, K.P.; RAU, A.R.P.; HOMBERGER, D.G.; Louisiana State University, Baton Rouge; currently University of Georgia, Athens; Louisiana State University, Baton Rouge; Louisiana State University Health Sciences Center, New […]
Twist and Flex Locomotor Variation in Elongate Fishes
Meeting Abstract 122-3 Thursday, Jan. 7 10:45 Twist and Flex: Locomotor Variation in Elongate Fishes DONATELLI, CM*; SUMMERS, AP; TYTELL, ED; Tufts University; University of Washington; Tufts University cassandra.donatelli@tufts.edu http://ase.tufts.edu/biology/labs/tytell/ Fish swim by passing a wave of motion from their heads, through the body, to the tail which produces thrust. In addition to the yaw motion of […]
Three-dimensional flow patterns around swimming lamprey Petromyzon marinus
Meeting Abstract 122-4 Thursday, Jan. 7 11:00 Three-dimensional flow patterns around swimming lamprey Petromyzon marinus LEHN, A.M.*; COLIN, S.P.; COSTELLO, J.H.; TYTELL, E.D.; MIT; Roger Williams University; Providence College; Tufts University lehn@mit.edu Unlike many bird and insect wings, the fins of fishes have a very low aspect ratio: their span is small compared to their chord length, […]
