Meeting Abstract 53.3  Thursday, Jan. 6  Reflexes and running: Modeling neural feedback in a running cockroach PROCTOR, Joshua/L*; HOLMES, Philip; Princeton University jproctor@princeton.edu We have developed an integrated model for insect locomotion that includes a central pattern generator (CPG), nonlinear muscles, hexapedal geometry and a representative proprioceptive sensory pathway. In previous work, we have investigated the role […]

Meeting Abstract 53.1  Thursday, Jan. 6  Neuroadaptive control algorithms for autonomous chemical plume tracking VOLYANSKYY, K.*; WEBSTER, D.R.; WEISSBURG, M.J.; Georgia Inst. of Techn., Atlanta; Georgia Inst. of Techn., Atlanta; Georgia Inst. of Techn., Atlanta gtg891s@mail.gatech.edu We designed and implemented a series of adaptive controllers for autonomous chemical plume tracking in a turbulent flow environment. In our […]

Meeting Abstract 53.2  Thursday, Jan. 6  Kinematics of tongue-flicking in garter snakes (Thamnophis sirtalis) RYERSON, W.G.*; SCHWENK, K.; Univ. of Connecticut; Univ. of Connecticut william.ryerson@uconn.edu The forked tongue of snakes is used to gather environmental chemicals (odorants) and to deliver them to the vomeronasal organs in the roof of the mouth. Snakes use two methods to sample […]

Meeting Abstract 53.6  Thursday, Jan. 6  Escape responses of larval fish to a predator’s strike FEITL, KE*; NGO, V; MCHENRY, MJ; Univ. of California, Irvine; Univ. of California, Irvine; Univ. of California, Irvine kfeitl@uci.edu Larval fish use the lateral line system to sense the water flow created by a predator’s strike. Despite its potential importance to survival, […]

Meeting Abstract 53.5  Thursday, Jan. 6  Building a virtual biomechanical model of the Bullfrog skeleton UYENO, Theodore A*; GILLES, Benjamin; SUEDA, Shinjiro; LEE, David; WILKINSON, Kit; GISZTER, Simon F. ; PAI, Dinesh K.; NISHIKAWA, Kiisa C. ; NAU; UBC; UBC; UNLV; NAU; Drexel Univ.; UBC; NAU ted.uyeno@nau.edu In developing a quantitative understanding of bullfrog motor control, we […]

Meeting Abstract 52.5  Thursday, Jan. 6  Warming up and cooling down after a very large hot drink by blood-sucking bugs (Rhodnius prolixus) LOUDON, C.*; BRADLEY, T.J.; Univ. of California, Irvine; Univ. of California, Irvine cloudon@uci.edu As small ectotherms, insects are subject to rapid changes in body temperature following changes in their thermal environment. Blood-sucking bugs of the […]

Meeting Abstract 52.4  Thursday, Jan. 6  Using sunglasses to find the best burger in town: Polarization vision as a camouflage breaker in pelagic predators JOHNSEN, S*; MARSHALL, N.J.; Duke Univ.; Univ. of Queensland sjohnsen@duke.edu Because light in the pelagic environment is partially polarized, it has been suggested that the polarization sensitivity found in certain pelagic species may […]

Meeting Abstract 52.1  Thursday, Jan. 6  Tidal ventilation of sea turtle nests HONARVAR, Shaya; O’CONNOR, Michael*; Drexel Univ.; Drexel Univ. mike.oconnor@drexel.edu Sea turtles bury their nests as much as 70-80 cm deep and the sand above the nest represents an important resistance to respiratory gas exchange. Tidal movements of the water table under the nest can ventilate […]

Meeting Abstract 52.6  Thursday, Jan. 6  Foraging activity of the whelk Nucella ostrina in manipulated tidal regimes CARRINGTON, E*; KULL, K; UW Friday Harbor Laboratories ecarring@uw.edu An important first step in developing a biophysical model to predict body temperature is to characterize the microhabitat in which the organism lives. This can be difficult for mobile organisms in […]

Meeting Abstract 52.2  Thursday, Jan. 6  Dietary calcium, maternal skeletal condition and lifetime reproductive performance of white-footed mice (Peromyscus leucopus) BOOHER SCHMIDT, C.M.*; HOOD, W.R.; Auburn University, Alabama; Auburn University, Alabama cmb0011@auburn.edu To maximize lifetime reproductive success, females must balance investment in current reproduction with the potential impact of that investment on her body condition. Several mammalian […]
