DALEY, M.A.; CARD, G.; BIEWENER, A.A.: Effective Mechanical Advantage of the guinea fowl hindlimb during steady and variable speed running Animals live in an unpredictable environment and rarely move at constant speeds. Thus, muscle function under non-steady conditions (acceleration, deceleration) is a critical component of locomotor system design. Previous studies have suggested that, during steady […]

Hedrick, T.L.*; Tobalske, B.W.; Biewener, A.A.: 3D Kinematic Analysis of Lift Production Over a Range of Speeds in Ring-necked Doves and Cockatiels A central problem limiting our understanding of the aerodynamics of avian flight is the lack of 3D kinematic data of wing motion. The lift generated by a wing is proportional to 1) the […]

Lee, D. V.: Relating limb geometry to ground reaction force in running quadrupeds: A design for stability? A defining characteristic of legged locomotion is forward movement of the body over the feet, which remain more-or-less fixed with respect to the ground. This mandates that, in quadrupeds, the limbs retract about their proximal joints (i.e., hip […]

Hsieh, S.T.: Ontogenetic 3-D kinematics of water running in green basilisk lizards (Basiliscus plumifrons) Most research on tetrapod locomotion has focused on movement over solid substrates. The question of how animals locomote on fluid substrates is just beginning to be explored. Basilisk lizards are known for their ability to run across the surface of water […]

CARRIER, D.R.*; LEE, D.V.; WALTER, R. M.: INFLUENCE OF ROTATIONAL INERTIA ON THE TURNING PERFORMANCE OF THEROPOD DINOSAURS. Turning agility of theropod dinosaurs may have been severely limited by the large rotational inertia of their horizontal trunks and tails. Bodies with mass distributed far from the axis of rotation have much greater rotational inertia than […]

CARRANO, M. T.: Homology and the evolution of non-avian dinosaur locomotion Non-avian dinosaurs diversified throughout the Mesozoic from a single bipedal, parasagittal-limbed ancestor. Their 140-my radiation spanned over three orders of magnitude in body size and included eight major clades. In spite of this, diversification within the dinosaurian locomotor apparatus appears to have been comparatively […]

Higham, T.E.*; Davenport, M.; Mattingly, W.B.; Jayne, B.C.: Effects of turning angle on sprinting performance of three ecomorphs of arboreal lizards Most studies on the locomotion of animals are for straight, steady speed movements; however, many species often perform maneuvering or intermittent locomotion in their natural habitats. Lizards, including several arboreal species, have been common […]

IRSCHICK, D.J.*; JAYNE, B.C.: A comparative field study of the arboreal locomotion of lizards Few studies have rigorously quantified the habitat and movements of arboreal animals, particularly in a comparative context. We quantified the available habitat, habitat use and movement patterns of three morphologically different arboreal Anolis lizard species at a field site in Jamaica […]

NISHIGUCHI, M.K.*: Reverse physiological patterns between sepiolid squids and their luminous bacterial symbionts: Host specificity examined from down under. Mutualistic associations between bacteria and their eukaryotic hosts have a variety of mechanisms that determine patterns of host specificity among symbionts during infection and colonization. Although most symbiotic bacteria are only capable of infecting their particular […]

Lickliter, C.L.*; Nishiguchi, M.K.: Phylogenetic characterization of the genus Vibrio based on morphological and molecular data. Vibrio fischeri and Vibrio logei are two species of luminous bacteria (GAMMA-Proteobacteria) that reside as symbionts in the light organs of a variety of sepiolid squids (Cephalopoda: Family Sepiolidae). These squids include the genera Euprymna and Sepiola, which are […]
