Meeting Abstract S11.2  Wednesday, Jan. 6  Genetic architecture of body shape divergence in sticklebacks PEICHEL, Catherine L; Fred Hutchinson Cancer Research Center cpeichel@fhcrc.org Fishes exhibit enormous diversity in body shape. The ability to evolve such different shapes may have contributed to the successful radiation of fishes and their ability to exploit a wide variety of aquatic habitats. […]

Meeting Abstract S11.6  Wednesday, Jan. 6  From optimized swimming performance to optimal body shapes TOKIć, Grgur*; YUE, Dick K.P.; Massachusetts Institute of Technology; Massachusetts Institute of Technology yue@mit.edu We address the question of whether the body geometry and motion characteristic of fish can be deduced directly from mechanical and hydrodynamical considerations. The mechanics and fluid mechanics of […]

Meeting Abstract S11.3  Wednesday, Jan. 6  Environment, Additive Genetic Variance and Evolvability of Body Shape in Threespine Stickleback (Gasterosteus aculeatus) MCGUIGAN, K*; NISHIMURA, N; CURREY, M; HURWIT, D; CRESKO, WA; Univ. Queensland; Univ. Oregon; Univ. Oregon; Univ. Oregon; Univ. Oregon k.mcguigan1@uq.edu.au Numerous examples of rapid adaptation of populations to novel habitats have been documented. An unanswered question […]

Meeting Abstract S11.9  Wednesday, Jan. 6  Eddies: Potential impacts of turbulence on fish-swimming form and function WEBB, Paul W*; COTEL, Aline J; University of Michigan, Ann Arbor; University of Michigan, Ann Arbor pwebb@umich.edu Ideas on the relationships between water flow and form of fishes over the past century are derived largely from assumptions of relatively steady flow. […]

Meeting Abstract S11.4  Wednesday, Jan. 6  Axial Elongation in Fishes: Using Morphological Approaches to Elucidate Developmental Mechanisms in Studying Body Shape WARD, A. B.*; MEHTA, R. S.; Adelphi University; Univ. of California, Davis award@adelphi.edu Fishes are highly variable in body shape: from nearly spheroidal in some Tetraodontiformes to extremely elongate in Anguilliformes. The elongate body shape has […]

Meeting Abstract S11.10  Friday, Jan. 7  Wing Assisted Locomotion of a 25 g Running Robot PETERSON, K.*; BIRKMEYER, P.; DUDLEY, R.; FEARING, R. S.; University of California, Berkeley; University of California, Berkeley; University of California, Berkeley; University of California, Berkeley kevincp@eecs.berkeley.edu Current arguments for both cursorial and arboreal theories of vertebrate flight origins derive from limited fossil […]

Meeting Abstract S11.4  Friday, Jan. 7  The evolution of the vestibular system and controlled aerial descent in non-specialized arboreal squamates HERREL, A*; BOISTEL, R; LOSOS, J; VANHOOYDONCK, B; MNHN/CNRS; Universite de Poitiers; Harvard University; University of Antwep anthony.herrel@mnhn.fr Controlled aerial descent has evolved at least 30 times independently in different vertebrate and invertebrate lineages. A whole suite […]

Meeting Abstract S11.6  Friday, Jan. 7  The Evolution of Gliding Performance in Flying Lizards (Draco) MCGUIRE, J A*; DUDLEY, R; Univ. of California, Berkeley mcguirej@berkeley.edu The flying lizards of the genus Draco are arboreal gliders that occur throughout the dipterocarp-dominated rainforests of SE Asia. The assemblage is comprised of approximately 45 species, all of which share a […]

Meeting Abstract S11.11  Friday, Jan. 7  Swifts have an edge on drag reduction LENTINK, D*; DE KAT, R; Wageningen University; Delft University of Technology david.lentink@wur.nl Bird wings are buildup by overlapping feathers, which gives the wing a wavy surface with distinct edges formed by the rachis. The aerodynamic function of this wavy surface roughness is unclear. To […]

Meeting Abstract S11.7  Friday, Jan. 7  Ecological and biomechanical insights into the origins of gliding in mammals BYRNES, G.*; SPENCE, A. J.; University of Cincinnati; Royal Veterinary College byrnesgt@ucmail.uc.edu Gliding has evolved independently at least six times in mammals. Multiple untested hypotheses have been proposed to explain the origins of gliding. These include predator evasion, economical locomotion […]
