Meeting Abstract 57.3  Jan. 6  Natural substratum topography and its relation to the prolific adhesive capacity of geckos RUSSELL, A. P.*; JOHNSON, M. K.; Univ. of Calgary; Univ. of Calgary arussell@ucalgary.ca Many taxa of gekkonid lizards have subdigital pads bearing fields of adhesive setae that allow them to bond to and climb on a wide variety of […]

Meeting Abstract 57.6  Jan. 6  Kinematics of level terrestrial and underwater walking in the California newt, Taricha torosa ASHLEY-ROSS, M.A.*; LUNDIN, R.; JOHNSON, K.L.; Wake Forest University rossma@wfu.edu Although fossil evidence indicates that the tetrapod limb predated the move onto land, underwater locomotion involving the limbs, and how it might differ from locomotion on land, is poorly […]

Meeting Abstract 57.2  Jan. 6  Effects of substrate on the terrestrial locomotion of the ropefish. PACE, C. M.*; GIBB, A. C.; Northern Arizona University; Northern Arizona University Cinnamon.Pace@nau.edu The ropefish, Erpetoichthys calabaricus, is an elongate polypterid that makes terrestrial excursions. Because ropefish rely on body-substrate interactions to produce forward thrust, the nature of the substrate likely affects […]

Meeting Abstract 57.5  Jan. 6  Effects of perch diameter and incline on the arboreal locomotion of snakes ASTLEY, H. C.*; JAYNE, B. C.; Univ. of Cincinnati; Univ. of Cincinnati astleyhc@email.uc.edu Moving in arboreal habitats poses several functional challenges including variable branch diameters, inclines, grasping, balancing and fitting onto the limited width of the perch. In contrast to […]

Meeting Abstract 57.4  Jan. 6  Distal hindlimb muscles play a key role in stability of running over rough terrain DALEY, M.A.*; BIEWENER, A.A.; University of Michigan, Ann Arbor; Harvard University, Cambridge mdaley@umich.edu Using a novel obstacle treadmill experiment, we test the hypothesis that distal limb muscles rapidly modify work output for stabilization tasks. We examine the in-vivo […]

Meeting Abstract 56.1  Jan. 6  Swimming posture switches from visual to vestibular control in developing larval southern flounder SCHREIBER, A.M.; Carnegie Institution, Embryology schreiber@ciwemb.edu Flatfish transform from symmetric, upright-swimming larvae into asymmetric juveniles that swim on one side. Lateralized posture develops independent of eye position during metamorphosis, suggesting strong vestibular, as opposed to visual, involvement. This study […]

Meeting Abstract 56.4  Jan. 6  Relaxed selective constraints on Hox clusters of ray-finned fishes: Patterns and frequencies of mobile DNA element insertions RAINCROW, J.R.*; GAO, L.Z.; AMEMIYA, C.; CHIU, C.H.; Rutgers University; Rutgers University; VMRC, Seattle, Washington; Rutgers University raincrow@biology.rutgers.edu Hox genes, which share sequence homology with the Hom-C genes of Drosophila, originated early in metazoan evolution […]

Meeting Abstract 56.3  Jan. 6  Position, distance and hydrodynamic effects on fertilization success of the green sea urchin Strongylocentrotus droebachiensis. KREGTING, L.T*; YUND, P.O; THOMAS, F.I.M; GRABOWSKI, R.C; University of New England; University of New England; University of Hawaii; University of South Florida lkregting@une.edu The distance and location between free spawning invertebrates such as sea urchins can […]

Meeting Abstract 56.2  Jan. 6  Functional analysis of cis-regulatory evolution in humans and other primates BABBITT, Courtney C.*; WRAY, Gregory A.; Center for Evolutionary Genomics, Institute for Genome Science and Policy, Duke University; Center for Evolutionary Genomics, Institute for Genome Science and Policy, Duke University courtney.babbitt@duke.edu Due to the extensive similarities in coding regions between humans and […]

Meeting Abstract 56.6  Jan. 6  Evolution of murine dentitions along the path of least developmental resistance KAVANAGH, KD*; EVANS, A; JERNVALL, J; University of Helsinki, Finland; University of Helsinki, Finland; University of Helsinki, Finland kathryn.kavanagh@helsinki.fi We report discovery of a developmental rule governing relative molar sizes in the mouse Mus musculus, and, by a macroevolutionary test, we […]
