Meeting Abstract 101.2 Saturday, Jan. 7 FOSSILS, MOLECULAR PHYLOGENIES, AND MODELS OF TRAIT EVOLUTION SLATER, G.J.*; HARMON, L.J.; ALFARO, M.E.; Univ. of California, Los Angeles; Univ. Idaho; Univ. of California, Los Angeles gslater@ucla.edu Evolutionary biologists are increasingly interested in assessing the fit of evolutionary models to phylogenetic comparative data. By identifying the best-fitting model of trait evolution, […]

Early evolution of elevated growth and metabolic rates in archosaurs
Meeting Abstract 101.3 Saturday, Jan. 7 Early evolution of elevated growth and metabolic rates in archosaurs WERNING, S*; IRMIS, RB; NESBITT, SJ; SMITH, ND; TURNER, AH; PADIAN, K; Univ of California, Berkeley; Univ of Utah; Univ of Washington; The Field Museum; Stony Brook Univ; Univ of California, Berkeley swerning@berkeley.edu Birds exhibit much higher growth and metabolic rates […]
Analyzing continuous character evolution on a phylogeny
Meeting Abstract 101.4 Saturday, Jan. 7 Analyzing continuous character evolution on a phylogeny REVELL, Liam J.; Univ. of Massachusetts Boston liam.revell@umb.edu Recent years have seen the development of likelihood-based phylogenetic methods that allow researchers to test the hypothesis that a discrete character trait (for example, habitat type or trophic level) influences the rate of evolution for a […]
The role of head stabilization in the flight control system of hawkmoths
Meeting Abstract 101.2 Sunday, Jan. 6 The role of head stabilization in the flight control system of hawkmoths WINDSOR, S.P.*; TAYLOR, G.K.; Univ. of Oxford; Univ. of Oxford shane.windsor@zoo.ox.ac.uk During flight many insects actively stabilize their head relative to their surroundings. Gaze stabilization acts to significantly simplify the processing and extraction of relevant visual information but in […]
Moths respond to inertial yaw rotations with lateral abdominal movements
Meeting Abstract 101.4 Sunday, Jan. 6 Moths respond to inertial yaw rotations with lateral abdominal movements. DICKERSON, BH*; HOWELL, DB; DANIEL, TL; University of Washington bdicker@uw.edu Multimodal sensory information processing is a key component of insect flight control. While visual information is crucial, mechanoreception serves an equally important role because of its relatively fast processing time. For […]
How the hawkmoth Manduca sexta moves left and right
Meeting Abstract 101.1 Sunday, Jan. 6 How the hawkmoth Manduca sexta moves left and right GREETER, JSM*; HEDRICK, TL; Univ. of North Carolina at Chapel Hill jgreeter@live.unc.edu Understanding flight control strategies in insects is essential for drawing a complete picture of the evolutionary and biomechanical underpinnings of flapping flight. Many flying animals can produce lateral “sideslip” maneuvers, […]
Efficiency of lift production in six species of hawk moths
Meeting Abstract 101.3 Sunday, Jan. 6 Efficiency of lift production in six species of hawk moths HENNINGSSON, P.*; BOMPHREY, R. J.; Univ. of Oxford, UK; Univ. of Oxford, UK per.henningsson@zoo.ox.ac.uk The efficiency of lift production is important for all flying animals because it directly influences the limits of performance. For both fixed-wing vehicles and flapping animals the […]
Agile airframes II closing the loop on abdominal actuation
Meeting Abstract 101.6 Sunday, Jan. 6 Agile airframes II: closing the loop on abdominal actuation COLMENARES, DJ*; DYHR, JP; MORGANSEN, KA; DANIEL, TL; Univ. of Washington; Univ. of Washington; Univ. of Washington; Univ. of Washington djc26@uw.edu Flying organisms achieve flight stability by employing a multitude of control surfaces, most notably the wings. However, airframe deformations, such as […]
Agile airframes I maneuverability from abdominal actuation
Meeting Abstract 101.5 Sunday, Jan. 6 Agile airframes I: maneuverability from abdominal actuation DYHR, JP*; COWAN, NJ; MORGANSEN, KA; DANIEL, TL; Univ. of Washington; Johns Hopkins Univ.; Univ. of Washington; Univ. of Washington jdyhr@uw.edu Flying animals face trade-offs between maintaining stability versus the ability to accomplish quick maneuvers. Unlike terrestrial or aquatic locomotion, flight requires the active […]
Using 3-D printing technology to investigate the function of cranial lateral line canals in fishes during rheotaxis
Meeting Abstract 101.1 Wednesday, Jan. 7 08:00 Using 3-D printing technology to investigate the function of cranial lateral line canals in fishes during rheotaxis LIAO, JC*; AKANYETI, O; The Whitney Lab for Marine Bioscience, U. Florida Gainesville jliao@whitney.ufl.edu http://www.liaolab.com/ The cranial lateral line canals (CLLC) of fishes are a mechano-receptive sensory system that can detect pressure gradients […]
