Meeting Abstract 38.5  Monday, Jan. 5  Semicircular Canal Morphology as Evidence of Sensory Adaptation to Locomotor Environment in Amniotes GEORGI, Justin A; Midwestern University, Glendale, AZ jgeorg@midwestern.edu The vestibular system is a critical component of the neural control of locomotion in vertebrates. Integrated in the cerebellum with visual and proprioceptive inputs, the signals from the semicircular ducts […]

Meeting Abstract 38.4  Monday, Jan. 5  Optics of an alternative imaging system, the facial pits of Pitvipers (Viperidae: Crotalinae) COLAYORI, Samantha E*; BAKKEN, George S.; Indiana State University, Terre Haute gbakken@indstate.edu Facial pits are specialized organs possessed by pitvipers (Viperidae: Crotalinae) that detect emitted thermal radiation. Optically, they apparently function like a pinhole camera eye. The image […]

Meeting Abstract 38.2  Monday, Jan. 5  Decoding Cockroach Antennal Tactile Navigation Using Naturalistic and White Noise Stimuli in a Control Theoretic Framework SPONBERG, S.*; MONGEAU, J.M.; MILLER, J.P.; FULL, R.J.; Univ. of CA, Berkeley; Univ. of CA, Berkeley; Montana St. Univ.; Univ. of CA, Berkeley sponberg@berkeley.edu Control theoretic models for stabilization and navigation behaviors provide a framework […]

Meeting Abstract 37.1  Monday, Jan. 5  Worms as wedges: Effects of sediment mechanics on burrowing behavior DORGAN, Kelly M*; ARWADE, Sanjay R; JUMARS, Peter A; University of California, Berkeley; University of Massachusetts, Amherst; University of Maine kelly.dorgan@berkeley.edu Marine muds are elastic solids through which animals move by propagating a crack-shaped burrow. Fracture mechanics depend on material stiffness […]

Meeting Abstract 37.3  Monday, Jan. 5  Simultaneous correlation of odor-plume structure and behavior: II. Signal contrast at walking legs elicits steering in tracking blue crabs WEISSBURG, M.J*; DICKMAN, D.B.; PAGE, J.L; WEBSTER, D.R.; Georgia Inst. Technology; Georgia Inst. Technology; Georgia Inst. Technology; Georgia Inst. Technology marc.weissburg@biology.gatech.edu Animals may use different sensor populations to regulate specific tasks during […]

Meeting Abstract 37.6  Monday, Jan. 5  Sensory input for routine turns in larval zebrafish DANOS, Nicole; Harvard University ndanos@oeb.harvard.edu Early locomotor behavior in zebrafish is highly stereotyped. In this study, I investigate the effects of the physical environment on the development of this early locomotor behavior. Specifically, I seek to determine which aspects of normal behaviors are […]

Meeting Abstract 37.5  Monday, Jan. 5  Nonlinear integration of proprioceptive inputs to the lamprey central pattern generator for locomotion TYTELL, E.D.*; COHEN, A.H.; Univ. of Maryland, College Park; Univ. of Maryland, College Park tytell@umd.edu When animals move, they receive feedback from numerous proprioceptive sensors. These sensors relay information on body movement to the spinal cord and brain, […]

Meeting Abstract 37.2  Monday, Jan. 5  Antennae mediate an abdominal flexion response to body rotations in the hawkmoth Manduca sexta HINTERWIRTH, A.J.*; DANIEL, T.L.; University of Washington; University of Washington ahinterw@u.washington.edu The crepuscular moth Manduca sexta does not rely on vision alone for flight control. It uses mechanosensory information from its antennae to mediate rapid responses to […]

Meeting Abstract 36.7  Monday, Jan. 5  Studying cues for species identification using robotic lizards in the field ORD, TJ*; STAMPS, JA; Harvard University / Univ. of California, Davis; Univ. of California, Davis tord@oeb.harvard.edu Theory suggests that territorial animals should recognize and selectively respond to species-specific components of displays used in territorial defense. We examined whether the territorial […]

Meeting Abstract 36.4  Monday, Jan. 5  Sound Strategies: Acoustic Aposematism, Mimicry, and Sonar Jamming in the Bat-Moth Arms Race. CORCORAN, Aaron/J.; BARBER, Jesse/R.; CULLEN, Megan/A.; CONNER, William/E.*; Wake Forest University; Colorado State University; Wake Forest University; Wake Forest University conner@wfu.edu Moths have long engaged in an evolutionary arms race to avoid capture by bats. Tiger moths (Lepidoptera: […]
