Wing Reduction and Flight Biomechanic in Stick Insects (Insecta Phasmatodea)
Meeting Abstract 98.6 Saturday, Jan. 7 Wing Reduction and Flight Biomechanic in Stick Insects (Insecta: Phasmatodea) ZENG, Yu*; DUDLEY, Robert; Univ. of California, Berkeley; Univ. of California, Berkeley dreavoniz@berkeley.edu Many unresolved questions in insect flight evolution relate to the transition between flightless and flying insects. Functional analysis of transitional forms using anatomical intermediates may help to explain […]
Resilin and the morphological basis of flexible wing dynamics in flying insects
Meeting Abstract 98.5 Saturday, Jan. 7 Resilin and the morphological basis of flexible wing dynamics in flying insects MOUNTCASTLE, AM*; COMBES, SA; Harvard University mountcastle@fas.harvard.edu Flexible insect wings undergo considerable shape changes during flapping flight, and the importance of these emergent deformations to force production and aerodynamic efficiency has been the focus of many recent studies. Relatively […]
Relative role of hindlimbs and forelimbs during take-off and landing in different species of birds
Meeting Abstract 98.1 Saturday, Jan. 7 Relative role of hindlimbs and forelimbs during take-off and landing in different species of birds PROVINI, Pauline*; ABOURACHID, Anick; Muséum National d’Histoire Naturelle, Paris; Muséum National d’Histoire Naturelle, Paris provini@mnhn.fr Although take-off and landing are crucial components of avian flight, few studies have focused on these two phases and consequently the […]
Free-flight dynamics of peregrine and pigeon – predator and prey
Meeting Abstract 98.3 Saturday, Jan. 7 Free-flight dynamics of peregrine and pigeon – predator and prey. USHERWOOD, JR; The Royal Veterinary College jusherwood@rvc.ac.uk Newly developed GPS and inertial loggers record high rate and quality in a small package. This allows direct measurements of free flight and flock dynamics in birds down to the size of pigeons. Findings […]
Dragonfly versus fruit fly Biomechanics, behavior and strategy during aerial predator-prey encounters
Meeting Abstract 98.4 Saturday, Jan. 7 Dragonfly versus fruit fly: Biomechanics, behavior and strategy during aerial predator-prey encounters COMBES, S.A.*; RUNDLE, D.E.; IWASAKI, J.M.; Harvard University scombes@oeb.harvard.edu Despite extensive research on the ecology and population dynamics of predator-prey systems, our understanding of the physical interaction between animals and the factors that determine the outcome of an encounter […]
A new look at the avian wishbone
Meeting Abstract 98.2 Saturday, Jan. 7 A new look at the avian wishbone BAIER, D.B.*; GATESY, S.M.; DIAL, K.P.; JENKINS, F.A. Jr.; Providence College; Brown University; University of Montana; Harvard University dbaier@providence.edu The V-shaped avian furcula (fused clavicles) spans between the shoulders and is known to be capable of considerable bending in most species. Earlier studies of […]
The silent flight of owls
Meeting Abstract 97.2 Saturday, Jan. 7 The silent flight of owls BACHMANN, Thomas; Technische Universität Darmstadt, Germany bachmann@sla.tu-darmstadt.de Barn owls are nocturnal birds of prey that detect prey mainly by using acoustic information. To improve the localization of prey owls evolved a slow and silent flight. Here, anatomical adaptations of barn owl wings to low speed and […]
Measurement of the aerodynamic stability and control effectiveness of human skydivers during free fall and directed aerial descent
Meeting Abstract 97.5 Saturday, Jan. 7 Measurement of the aerodynamic stability and control effectiveness of human skydivers during free fall and directed aerial descent EVANGELISTA, D.*; CARDONA, G.; RAY, N.; TSE, K.; WONG, D.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley devangel@berkeley.edu We examined […]
Flow visualization, kinematics, and metabolic rates of Anna’s Hummingbird hovering in ground effect
Meeting Abstract 97.3 Saturday, Jan. 7 Flow visualization, kinematics, and metabolic rates of Anna’s Hummingbird hovering in ground effect WOLF, Marta*; ORTEGA-JIMENEZ, Victor M.; KIM, Erica; DUDLEY, Robert; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley marta.wolf@berkeley.edu Animals in flight potentially benefit from an aerodynamic ground effect when moving […]
