Meeting Abstract 59.6 Jan. 7 Crocodylian Phylogeny & Cranial Ecomorphology SADLEIR, R.W.; Univ. of Chicago, Field Museum rsadleir@uchicago.edu Conflicting phylogenetic signals, character homoplasies, and character atavisms typify crocodylian phylogeny. Most phylogenetic ambiguity involves Gavialis and Tomistoma, for whom a secondary signal showing 70% of the characters supporting incongruent topologies is associated with their slender skull. Slender-snout skulls […]

Are radular tooth characters of the gastropod Conus informative for taxonomy and phylogeny
Meeting Abstract 59.1 Jan. 7 Are radular tooth characters of the gastropod Conus informative for taxonomy and phylogeny? KOHN, A.J.*; MEYER, C.P.; Univ. of Washington, Seattle; Univ. of California, Berkeley kohn@u.washington.edu Conus radular teeth are independently operating, hypodermic needle-like structures that inject paralytic neuropeptides to overcome prey. We tested the hypotheses that 1) they are sufficiently complex […]
A Systematic Revision of the Agriochoeridae (Cetartiodactyla Oreodontoidea)
Meeting Abstract 59.4 Jan. 7 A Systematic Revision of the Agriochoeridae (Cetartiodactyla: Oreodontoidea) LUDTKE, JA; San Diego State University joshualudtke@gmail.com Oreodonts, despite being a common component of Tertiary North American terrestrial faunas, lack a firm phylogenetic placement within Cetartiodactyla. Most workers agree that they are an early diverging`group, but disagreement exists as to whether oreodonts are more […]
Wing bending is modulated during flight and affects the induced flow field of Manduca sexta
Meeting Abstract 59.1 Saturday, Jan. 5 Wing bending is modulated during flight and affects the induced flow field of Manduca sexta. MOUNTCASTLE, A.M.*; DANIEL, T.L.; Univ.Washington, Seattle; Univ.Washington, Seattle danielt@u.washington.edu Most computational and physical models of insect flight assume that wings are rigid. However, many insect wings flex passively during flight. Large wing deformations occur in the […]
Unsteady aerodynamics of a flapping bird model
Meeting Abstract 59.2 Saturday, Jan. 5 Unsteady aerodynamics of a flapping bird model HUBEL, Tatjana*; TROPEA, Cameron; Darmstadt University of Technology; Darmstadt University of Technology tatjana_hubel@brown.edu This study investigates unsteady effects within the characteristic range of bird and large insect flight (Re 104 to 105). The influence of flapping frequency, angle of attack and amplitude was analyzed […]
The effect of loading on flight kinematics of bats a case of kinematic plasticity
Meeting Abstract 59.5 Saturday, Jan. 5 The effect of loading on flight kinematics of bats: a case of kinematic plasticity IRIARTE, J.**; RISKIN, D.K.; SWARTZ, S.M.; Brown University; Brown University; Brown University jose_iriarte@brown.edu All bats experience daily and seasonal fluctuation in body mass. Presumably, an increase in mass requires changes in flight kinematics to produce the extra […]
Proper orthogonal decomposition of bat flight kinematics
Meeting Abstract 59.6 Saturday, Jan. 5 Proper orthogonal decomposition of bat flight kinematics RISKIN, D. K.*; WILLIS, D. J.; HEDRICK, T. L.; IRIARTE-DIAZ, J.; LAIDLAW, D. J.; BREUER, K. S.; SWARTZ, S. M.; Brown University; Massachusetts Institute of Technology; University of North Carolina; Brown University; Brown University; Brown University; Brown University dkr8@brown.edu It is not known how […]
Perturbation compensation in hovering flight
Meeting Abstract 59.4 Saturday, Jan. 5 Perturbation compensation in hovering flight HEDRICK, TL; University of North Carolina at Chapel Hill thedrick@bio.unc.edu Biological locomotor systems are often lauded for their robustness, or their ability to reject perturbations to their trajectory or orientation. However, the underlying properties of organisms that enable robustness are not well understood but likely involve […]
Effects of experimental wing wear on standard and maximal flight performance in the European honey bee (Apis mellifera)
Meeting Abstract 59.3 Saturday, Jan. 5 Effects of experimental wing wear on standard and maximal flight performance in the European honey bee (Apis mellifera) VANCE, Jason T.*; ROBERTS, Stephen P.; Univ. of Nevada, Las Vegas; Univ. of Nevada, Las Vegas jason.vance@unlv.edu The wings of bees and other insects degrade over time, which affects foraging behavior and increases […]
Specialist and generalist herbivores regulate food intake on diets containing novel plant compounds
Meeting Abstract 59.2 Tuesday, Jan. 6 Specialist and generalist herbivores regulate food intake on diets containing novel plant compounds TORREGROSSA, A-M*; AZZARA, A. V.; DEARING, M.D.; University of Utah, Salt Lake City, UT; University of Utah, Salt Lake City, UT; Bristol Myers Squibb, Princeton, NJ torregrossa@biology.utah.edu Specialist herbivores are predicted to have evolved biotransformation pathways that can […]
