Meeting Abstract 26.3  Friday, Jan. 4  Sensory feedback loops in lamprey swimming TYTELL, E.D.*; COHEN, A.H.; Univ. of Maryland, College Park; Univ. of Maryland, College Park tytell@umd.edu In fishes, undulatory swimming is produced by sets of spinal interneurons constituting a central pattern generator (CPG). The CPG can produce the basic pattern for locomotion in the absence of […]

Meeting Abstract 26.2  Friday, Jan. 4  Multiple inputs mediate multiple outputs for flight control in Manduca sexta. HINTERWIRTH, Armin J*; DANIEL, Thomas L; University of Washington ahinterw@u.washington.edu The astounding aerodynamic ability of insects hinges upon the integration of multiple sensory modalities and upon motor outputs that drive multiple actuators (wings and abdominal motions correlate with sensory input). […]

Meeting Abstract 26.1  Friday, Jan. 4  Identification and characterization of chemoreceptive sensilla on the antennal flagellum of Palaemonetes pugio CASKEY, Jodi L*; WATSON, Glen M; University of Louisiana at Lafayette; University of Louisiana at Lafayette shrimpgirl@louisiana.edu Innervated structures (sensilla) on the external cuticle provide crustaceans with information about their external chemical environment. The antennules of crustaceans are […]

Meeting Abstract 26.4  Friday, Jan. 4  Genomic and gene regulatory signatures of cryptozoic adaptation in the red flour beetle Tribolium castaneum FRIEDRICH, Markus*; BAO, Riyue ; JACKOWSKA, Magdalena; LIU, Zhenyi; Wayne State University friedrichm@wayne.edu The many ways in which cryptozoic animals adapted to the light deprived biota of crevices, caverns, and caves arguably count as prime manifestations […]

Meeting Abstract 26.5  Friday, Jan. 4  Encoding characteristics of haltere mechanoreceptors FOX, J.L.*; DANIEL, T.L.; University of Washington; University of Washington jessfox@u.washington.edu Controlled dipteran flight requires rapid acquisition of mechanosensory information provided by gyroscopic structures known as halteres. Halteres are modified hindwings that experience gyroscopic torques resulting from Coriolis forces that arise during body rotations. Although biomechanical […]

Meeting Abstract 26.2  Monday, Jan. 5  The Origins and Evolution of Metazoan Phototransduction Pathways:A History of Paraphyly and Derivation PLACHETZKI, D/C*; OAKLEY, T/H; Univ. of California, Santa Barbara; Univ. of California, Santa Barbara plachetzki@lifesci.ucsb.edu How does evolution proceed from common starting points and go on to generate the biodiversity we see today? The evolutionary origin of novel […]

Meeting Abstract 26.7  Monday, Jan. 5  The Origin of Conserved Protein Domains and Amino Acid Repeats Via Adaptive Competition RORICK, M.M.*; WAGNER, G.P.; Yale University; Yale University molly.rorick@yale.edu Some proteins, such as homeodomain transcription factors, contain highly conserved regions of sequence. It has been recently suggested that multiple conserved functional domains overlap and together explain the high […]

Meeting Abstract 26.8  Monday, Jan. 5  The Nuclear Receptor Complement of the Cnidarian Nematostella vectensis REITZEL, Adam R.; TARRANT, Ann M.*; Woods Hole Oceanographic Institution; Woods Hole Oceanographic Institution atarrant@whoi.edu Nuclear receptors (NRs) are a superfamily of metazoan transcription factors that regulate diverse developmental and physiological processes. We have identified the complete set of seventeen nuclear receptors […]

Meeting Abstract 26.1  Monday, Jan. 5  Opsin diversity and extra-ocular photorecepion in the Metazoa MARLOW, Heather Q.*; SPEISER, Daniel I.; SEAVER, Elaine C.; MARTINDALE, Mark Q.; University of Hawaii at Manoa; Duke University; University of Hawaii at Manoa; University of Hawaii at Manoa marlow@hawaii.edu Bilaterian animals (protostomes and deuterostomes) sense light through the use of visual opsins, […]

Meeting Abstract 26.3  Monday, Jan. 5  Molecular evolution of light detection in a bioluminescent squid PANKEY, M.S.*; MCFALL-NGAI, M.N.; OAKLEY, T.H.; University of California, Santa Barbara; University of Wisconsin; University of California, Santa Barbara mpankey@lifesci.ucsb.edu Identifying the molecular bases of adaptive changes leading to novelty and increased complexity is one of the central goals of modern evolutionary […]
