HOLM, E.R.; ORIHUELA, B.; RITTSCHOF, D.; Naval Surface Warfare Center, Carderock Division; Duke University Marine Laboratory; Duke University Marine Laboratory: Genetic variation in adhesive tenacity and adhesive plaque characteristics in the barnacle Balanus amphitrite Silicone fouling-release coatings represent a reputedly non-toxic alternative to current toxic antifouling coatings, for controlling hull fouling. In contrast to antifouling […]

MARTONE, P.T.; Hopkins Marine Station, Stanford University: Adapting to wave forces: tissue strengthening in an intertidal, articulated coralline alga The decalcified joints (genicula) in the articulated coralline alga Calliarthron cheilosporioides are composed of a tissue that is much stronger than tissues from fleshy macroalgae. This tissue strength may contribute to the ability of articulated fronds […]

DIAL, K.P.*; TOBALSKE, T.W.; Univ. of Montana, Missoula; Univ. of Portland, Portland: WAIR Flow: Ontogeny of wing aerodynamics during incline running in birds. A survey of diverse avian clades (e.g, Tinamiformes, Galliformes, Columbiformes, and Passeriformes), shows wing-assisted incline running (WAIR) to be a plesiomorphic locomotor behavior. This includes Australian brush turkey chicks that are capable […]

BISHOP, K.L.; Brown University: Kinematics and performance in two species of mammalian gliders, Glaucomys volans and Petaurus breviceps Gliding has evolved independently in at least six lineages of mammals, all resulting in similar morphology and behavior. Investigations of the relationship between kinematics and gliding performance can provide insight into the mechanics of mammalian gliding. In […]

CLARK, Christopher J*; DUDLEY, Robert; UC Berkeley: Effects of tail length on hummingbird top speed, power curve, and parasite drag Hummingbirds (Trochlidae) exhibit enormous variation in their tail morphology and this variation is largely driven by sexual selection. One aerodynamic effect of an elongated tail may be to increase parasite (body) drag, by increasing the […]

TOBALSKE, B.W.**; WARRICK, D.R.; POWERS, D.R.; Univ. of Portland; Oregon State Univ.; George Fox Univ.: Effect of Wing Design on Wake Structure in Small Flying Birds Two species, rufous hummingbird (Selasphorus rufus , 3 g) and zebra finch (Taeniopygia guttata, 16 g) represent opposites with regard to wing design and kinematics among small birds. The […]

BUTLER, L. K.**; ROHWER, S; Burke Museum, University of Washington, Seattle; Burke Museum, University of Washington, Seattle: Correlations between flight demands and the structure of contour feathers in small birds Many studies have illustrated adaptations in birds to reduce the large aerodynamic and metabolic costs of flight, but no study has examined the relationship between […]

MILLER, L. A.; University of Utah: Clap and peel in insect flight with flexible and bristled wings In ‘typical’ insect flight, lift is produced when a leading edge vortex (LEV) is formed and remains attached to the wing and a trailing edge vortex (TEV) is formed and separates from the wing during each stroke. The […]

Meeting Abstract 43.1  Jan. 6  Variable Gearing in Pinnate Muscles AZIZI, E.*; ROBERTS, T.J.; Brown University; Brown University manny_azizi@brown.edu Pinnate muscles are characterized by short fibers that attach at an angle relative to the muscle�s line of action. Recent studies have shown that as obliquely oriented muscle fibers shorten they also rotate. Fiber rotation during a muscle […]
