Meeting Abstract S7-1.2.1 Jan. 6 Short- and long-term adaptation of the motor pattern for walking PEARSON, K.G.*; MCVEA, D.A.; University of Alberta, Edmonton; University of Alberta, Edmonton keir.pearson@ualberta.ca An obvious feature of animal locomotion is the ability to rapidly change motor patterns to adapt movements to a changing environment. Less obvious is the capacity to modify motor […]

Obstacle avoidance during walking
Meeting Abstract S7-1.2.2 Jan. 6 Obstacle avoidance during walking MCVEA, DA*; PEARSON, KG; University of Alberta; University of Alberta dmcvea@ualberta.ca Two basic features of animal locomotion are 1) avoidance of obstacles that either impede progress or endanger the animal, and 2) withdrawal responses from obstacles that unexpectedly contact the animal. In walking mammals, the former depends primarily […]
Form and Function of Identified Insect Motoneurons
Meeting Abstract S7-1.3.1 Jan. 6 Form and Function of Identified Insect Motoneurons DUCH, Carsten; Arizona State University carsten.duch@asu.edu Understanding complex neural circuitry requires an understanding of the functions of its basic components – individual neurons. A single neuron�s dendritic tree may receive thousands of input synapses. Input integration and computation are strongly affected by synapse distributions, dendritic […]
Changing Speeds in a Central Pattern Generator
Meeting Abstract S7-1.1.1 Jan. 6 Changing Speeds in a Central Pattern Generator SATTERLIE, Richard; University of North Carolina Wilmginton satterlier@uncw.edu Several common threads run through the fabric of central pattern generator networks, including those at the circuit level, such as reciprocal inhibition, at the cellular level, such as postinhibitory rebound, and at the molecular level, such as […]
An Inhibitory Spinal Reflex Between Elbow Flexor Synergists
Meeting Abstract S7-1.4.2 Jan. 6 An Inhibitory Spinal Reflex Between Elbow Flexor Synergists BARRY, BK*; ENOKA, RM; Univ. of Colorado, Boulder; Univ. of Colorado, Boulder Benjamin.Barry@colorado.edu Decades of work on spinal reflexes in humans based on measuring Hoffmann (H) reflexes in muscles of the forearm and lower leg has provided a relatively limited understanding of the modulation […]
The role of spatial and ontogenetic morphological variability in the spread of a tropical alga across barrier reefs and oceanic islands
Meeting Abstract S7-1.2 Saturday, Jan. 5 The role of spatial and ontogenetic morphological variability in the spread of a tropical alga across barrier reefs and oceanic islands STEWART, H.L.; Friday Harbor Labs, University of Washington hstewart@u.washington.edu Hydrodynamic conditions on barrier reef systems range from wave-driven flow on the forereef to slow unidirectional flow in protected lagoons. This […]
Swimming dynamics of squids throughout ontogeny
Meeting Abstract S7-1.3 Saturday, Jan. 5 Swimming dynamics of squids throughout ontogeny BARTOL, I.K.; Old Dominion University, Norfolk, VA ibartol@odu.edu Squids encounter vastly different flow regimes throughout ontogeny as they undergo critical morphological changes to their two locomotive systems: the fins and jet. Squid hatchlings (paralarvae) operate at low and intermediate Reynolds numbers (Re) and typically have […]
Size-dependent mode choices in aquatic locomotion
Meeting Abstract S7-1.1 Saturday, Jan. 5 Size-dependent mode choices in aquatic locomotion VOGEL, Steven; Duke University svogel@duke.edu All active fliers get about in a similar fashion, with oscillating wings; but aquatic locomotion, less constrained by gravity, offers a complex set of choices. Should swimming be done on the surface or submerged? If on the surface, should […]
Predictability of morphological differentiation across flow regimes in fishes
Meeting Abstract S7-1.5 Saturday, Jan. 5 Predictability of morphological differentiation across flow regimes in fishes LANGERHANS, Brian; Harvard University langerhans@oeb.harvard.edu Fish inhabit environments greatly varying in the intensities of water velocities experienced, and flow regime is generally believed to be of major evolutionary significance. While a sizeable volume of research has examined morphological variation across flow gradients […]
Morphological Selection in a Distinctive Flow Environment Body Shape and Waterfall-climbing Success in Hawaiian Stream Fishes
Meeting Abstract S7-1.4 Saturday, Jan. 5 Morphological Selection in a Distinctive Flow Environment: Body Shape and Waterfall-climbing Success in Hawaiian Stream Fishes BLOB, R.W.**; SCHOENFUSS, H.L.; MAIE, T.; CEDIEL, R.A.; PTACEK, M.B.; BRIDGES, W.C.; Clemson Univ.; St. Cloud State Univ.; Clemson Univ.; St. Cloud State Univ.; Clemson Univ.; Clemson Univ. rblob@clemson.edu Many fish species living in streams […]
